Step-by-step explanation:
The probability of drawing 2 red cards from a standard 52-card deck can be calculated as follows:
There are 26 red cards in the deck, so the probability of drawing a red card on the first draw is 26/52.
After the first card is drawn, there are 25 red cards remaining in the deck out of 51 total cards, so the probability of drawing a red card on the second draw is 25/51.
To find the probability of both events happening together (drawing 2 red cards), we multiply the probabilities of each event:
(26/52) * (25/51) = 0.245 or approximately 24.5%
Therefore, the probability of drawing 2 red cards in a standard 52 card deck is approximately 24.5%.

Craig needs to measure 2 3/8 cups. How many times must he fill a 1/3 cup measuring cup?
Answers
First, we need to convert the mixed number 2 3/8 to an improper fraction:
2 3/8 = (2 x 8 + 3) / 8 = 19/8
To find out how many times Craig needs to fill a 1/3 cup measuring cup, we can divide 19/8 by 1/3:
(19/8) / (1/3) = (19/8) x (3/1) = 57/8

Benjamin went shopping for a new phone
because of a sale. The price on the tag was
$28, but Benjamin paid $15. 40 before tax.
Find the percent discount
Answers
The percent discount on the phone because of a sale is 45%.
To find the percent discount, we need to calculate the difference between the original price and the discounted price, and then express that difference as a percentage of the original price.
First, let's find the difference between the two prices: $28 - $15.40 = $12.60. This means that Benjamin saved $12.60 on the phone.
Now, let's find the percent discount. We can do this by dividing the savings by the original price, and then multiplying the result by 100: ($12.60 / $28) * 100 = 45%.
So, Benjamin received a 45% discount on the phone before tax. This calculation shows that the sale allowed him to save a significant amount on his purchase. It's important to compare original and discounted prices to determine if a sale provides good value.

You have a 35-mile commute into work. Since you leave very early, the trip going to work is easier than the trip home. You can travel to work in the same time that it takes for you to make it 28 miles on the trip back home. Your average speed coming home is 10 miles per hour slower than your average speed going to work. What is your average speed going to work?
Answers
Average speed going to work is 50 mph.
What is average speed to work?Let's assume that the average speed going to work is "x" miles per hour.
Since you can travel to work in the same time it takes for you to make it 28 miles on the trip back home, we can set up an equation using the formula:
time = distance / speed
The time it takes to travel 35 miles to work is:
time to work = 35 / x
The time it takes to travel 28 miles on the return trip is:
time to return = 28 / (x - 10)
We know that both times are equal, so we can set them equal to each other and solve for "x":
[tex]35 / x = 28 / (x - 10)[/tex]
Multiplying both sides by x(x - 10), we get:
[tex]35(x - 10) = 28x[/tex]
Expanding the left side and simplifying, we get:
[tex]35x - 350 = 28x[/tex]
[tex]7x = 35[/tex]
[tex]x = 50[/tex]
Therefore, your average speed going to work is 50 miles per hour.
To solve this problem, we used the formula for speed, distance, and time. We t up an equation using the fact that the time it takes to travel to work is equal to the time it takes to travel 28 miles on the return trip. We then solved for the average speed going to work by setting the two times equal to each other and solving for "x". Finally, we found that the average speed going to work is 50 miles per hour.

(b) Calculate the surface area of the pyramid if a 10 and b = 12.
(c) If L=192 and a=b, find the value of a
Answers
Answer:
Step-by-step explanation:
(a) The total payment for a student who registers for m language subjects and n other subjects can be expressed as:
Total payment = Administrative fee + Tuition fee for language subjects + Tuition fee for other subjects
Total payment = RM30 + RM45m + RM40n
Total payment = RM30 + 45m + 40n
(b) For Zaleha who registers for 3 language subjects and 2 other subjects, the total payment can be calculated as:
Total payment = RM30 + (3 x RM45) + (2 x RM40)
Total payment = RM30 + RM135 + RM80
Total payment = RM245
(c) Chan pays RM280 when she registers for 2 language subjects and p other subjects. We can use the formula derived in part (a) to find the value of p:
Total payment = RM30 + (2 x RM45) + (p x RM40)
RM280 = RM30 + RM90 + RM40p
RM280 - RM120 = RM40p
RM160 = RM40p
p = 4
Therefore, Chan registers for 2 language subjects and 4 other subjects.
(a) The surface area of a right pyramid with a square base can be calculated as:
L = base area + 1/2 x perimeter of base x slant height
The base of the pyramid is a square, so its area can be expressed as:
Base area = a^2
The perimeter of the base can be calculated as:
Perimeter of base = 4a
The slant height can be calculated using the Pythagorean theorem:
slant height = sqrt(h^2 + (a/2)^2)
where h is the height of the pyramid.
Substituting these values in the surface area formula, we get:
L = a^2 + 1/2 x 4a x sqrt(h^2 + (a/2)^2)
L = a^2 + 2a x sqrt(h^2 + (a/2)^2)
(b) If a = 10 and b = 12, then the surface area of the pyramid can be calculated as:
L = 10^2 + 2 x 10 x sqrt(h^2 + (10/2)^2)
L = 100 + 20sqrt(h^2 + 25)
Given that L = 192, we can solve for h:
192 - 100 = 20sqrt(h^2 + 25)
92 = 20sqrt(h^2 + 25)
4.6 = sqrt(h^2 + 25)
4.6^2 - 25 = h^2
h^2 = 2.76
h = sqrt(2.76)
h ≈ 1.66
Substituting these values in the surface area formula, we get:
L = 10^2 + 2 x 10 x sqrt(1.66^2 + (10/2)^2)
L ≈ 314.9
Therefore, the surface area of the pyramid is approximately 314.9 square units.
(c) If L = 192 and a = b, then the surface area formula can be simplified as:
L = a^2 + 2a x sqrt(h^2 + (a/2)^2)
192 = a^2 + 2a x sqrt(h^2 + (a/2)^2)
We also know that the height of the pyramid is equal to the side length of the triangular faces. Since the pyramid is a right pyramid, the height and slant height are related by the Pythagorean theorem:
h^2 + (a/2)^

Answers
The volume of prism is 75.6 [tex]in^3[/tex]. The correct answer is option d,
We are given that the rectangle represents the base of a right rectangular prism and the height of the prism is 6 inches. To find the volume of the prism, we need to multiply the area of the rectangle by the height.
The area of the rectangle can be found by multiplying its length and width. However, we are not given any specific values for the length and width of the rectangle. Therefore, we cannot directly calculate its area.
Since we are given answer choices, we can use them to check which option gives the correct volume of the prism. We can start by assuming that the length, width, and height of the prism are integers, and then calculate the volume for each option until we find the one that matches.
Option a: 87.9 in^3 - This is not an integer, so we can eliminate this option.
Option b: 105.8 in^3 - This is not an integer, so we can eliminate this option.
Option c: 12.6 in^3 - This is too small, so we can eliminate this option.
Option d: 75.6 in^3 - To check if this is the correct answer, we can calculate the area of the rectangle by dividing the volume by the height.
Volume of the prism = area of rectangle x height
75.6 in^3 = (length x width) x 6 in
Length x width = 12.6 in^2
Now, we need to find two integers whose product is 12.6 in^2 and whose sum is 16 in (since the rectangle represents the base of a right rectangular prism). After some trial and error, we find that 3.15 in and 4 in satisfy these conditions.
Therefore, the length of the rectangle is 4 inches and the width is 3.15 inches.
Now, we can calculate the area of the rectangle by multiplying its length and width:
Area of rectangle = length x width = 4 in x 3.15 in = 12.6 in^2
Finally, we can calculate the volume of the prism:
Volume of prism = area of rectangle x height = 12.6 in^2 x 6 in = 75.6 in^3
Therefore, the correct answer is option d, 75.6 [tex]in^3[/tex].

308 = (1 - 0.825)x
308 = 0.175x
x = 308/0.175
Divide the values
x = 1760

Answers
The cost of a Powerade is $0.75 if 2 bags of chips and 2 Powerades cost $3.50 and one bag of chips and 3 Powerades cost $3.75.
Let the cost of one Powerade be x
The cost of one bag of chips be y
Cost of 2 bags of chips and 2 Powerades = $3.50
Cost of 2 bags of chips = 2y
Cost of 2 Powerades = 2x
2x + 2y = 3.50 ----(i)
Cost of one bag of chips and 3 Powerades= $3.75
Cost of 1 bag of chips = y
Cost of 3 Powerades = 3x

markup on retail: ?
a. 8%
b. 32%
c. 47%
d. 14%
Answers
The markup on retail is 47%. The correct option is c.
he markup on retail price is calculated to determine the percentage increase from the wholesale price to the retail price. In this case, the wholesale price is $17 and the retail price is $25. By subtracting the wholesale price from the retail price ($25 - $17),
we find that the markup is $8. Dividing this markup by the wholesale price ($8 / $17) gives us a ratio. Multiplying this ratio by 100 converts it to a percentage, which is approximately 47.06%.
This means that the retail price is approximately 47% higher than the wholesale price. Option c, 47%, correctly represents the calculated markup on the retail price.
Therefore, the markup on retail is 47%, so the answer is (c).

A student is buying a shirt that has a regular price of $18. After using a coupon, the price of the shirt is 0. 75x, where x is the regular price of the shirt. The clerk includes 6% sales tax on the price of the shirt. How much change should the student receive if the student pays for the shirt using a $20 bill?
Answers
The student should receive $5.69 in change.
How to find the price?The price of the shirt after the coupon is applied is 0.75 times the regular price, so:
Price of the shirt = 0.75x
If x = $18, then the price of the shirt is:
Price of the shirt = 0.75($18) = $13.50
The clerk adds 6% sales tax to the price of the shirt:
Sales tax = 6% of $13.50 = 0.06($13.50) = $0.81
So the total cost of the shirt is:
Total cost = $13.50 + $0.81 = $14.31
If the student pays with a $20 bill, the change the student should receive is:
Change = $20 - $14.31 = $5.69
Therefore, the student should receive $5.69 in change.

your investment to reach $5,000? Round to
the nearest tenth.
Answers
It will take approximately 15.27 years for your investment to reach $5,000 at a growth rate of 4.55% per year.
Using the compound interest calculation, we can determine how long it will take for your investment to grow to $5,000 at a growth rate of 4.55% per year:
[tex]A = P(\frac{1 + r}{n} )^(^n^t^)[/tex]
Where:
A = the final amount ($5,000)
P = the initial deposit ($2,500)
r = the interest rate (4.55%)
n = the number of times interest is compounded per year (assuming yearly compounding, n=1)
t = the number of years
Plugging in the values, we get:
[tex]\$5,000 = \$2,500(\frac{1 + 0.0455}{1} )^(^1^t^)[/tex]
Simplifying, we get:
[tex]2 = (1.0455)^t[/tex]
Taking the natural logarithm of both sides, we get:
ln(2) = t ln(1.0455)
Solving for t, we get:
t = ln(2) / ln(1.0455) = 15.27 years
Therefore, it will take approximately 15.27 years for your investment to reach $5,000 at a growth rate of 4.55% per year.

Answer:
(x-6)²+(y+3)²=17²
Step-by-step explanation:
The equation of a circle with center (a,b) and radius r is given by the formula:
(x - a)² + (y - b)² = r²
In this case, the center of the circle is (6,-3), and it passes through the point (-9,5). To find the radius of the circle, we need to calculate the distance between the center and the point on the circle. Using the distance formula, we get:
r = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(-9 - 6)² + (5 - (-3))²]
= √[225 + 64]
= √289
= 17
So, the radius of the circle is 17. Now we can plug in the values for the center and radius into the equation of a circle:
(x - 6)² + (y + 3)² = 17²

What numbers replace A B and C?
X -2 -1 0 1 2
Y 2 A B 2 C
Answers
The value of A, B and C from the given equation are 0, 0 and 6 respectively.
The given equation is y=x²+x.
Here, the table is
X -2 -1 0 1 2
Y 2 A B 2 C
When x=-1
y=(-1)²-1
y=0
So, A=0
When x=0
y=(0)²+0
y=0
So, B=0
When x=2
y=(2)²+2
y=6
So, C=6
Therefore, the value of A, B and C are 0, 0 and 6 respectively.
