1 ) Old Navy is offering a 20 % discount on all sweaters. If the regular price of a sweater is $45,what is the sale price?
Answer:
Sale Price = $36
Step-by-step explanation:
To find the sale price, you need to find what 10% of the original price is. 10% of $45 is $4.50. Now we need to find what 20% is, 20% is double 10% so we multiply the answer we got by 2. This equals to $9. The question is asking for the sale price, to find it you have to subtract $9 (the discount) from $45 (regular price). The answer you should get is $36.
Equation:
$45 ÷ 10 = $4.50
$4.50 × 2 = $9
$45 - $9 = $36

Candice and Phoebe are traveling on the same
highway in the same direction. Candice is
traveling at 45 mph and is exactly 40 miles
ahead of Phoebe who is traveling at 55 mph.
How many hours will it take Phoebe to catch
Candice?
Using proportions, it is found that it will take 4 hours for Phoebe to catch Candice.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Given their velocities, and the fact that they travel in the same direction, each hour, Phoebe gets 10 mph closer to Candice.
The initial distance is of 40 miles, 40/10 = 4, hence it will take 4 hours for Phoebe to catch Candice.

Find x
Pls help me.
Answer:
109
Step-by-step explanation:
as we can see x is an outer exterior angle and according to its property sum of an interior angle and an outer exterior angle = 180
The interior angle is 40+31 = 71
71 + x = 180
x = 180 -71
therefore x = 109
Divide. Write your answer as a fraction or a mixed number in simplest form. 4 3/4 / 5/6
Answer:
57/10 is the simplest form
Step-by-step explanation:
To divide fractions you need to do the reciprocal rules.
You also need to convert any mixed numbers to improper to make them easier to divide.
4 3/4 and 5/6 are your fractions.
4 3/4 converted into an improper fraction is 19/4
This is because the rule with this is that you take your whole number multiply it by the denominator and take the product and add it to the numerator.
19/4 divided by 5/6.
You need to flip 5/6 to 6/5 due to the reciprocal rules and also change the division sign to a multiplication sign.
19/4 x 6/5
You can multiply straight across!
19 x 6 and 4 x 5
19 x 6 = 114
4 x 5 = 20
Our answer: 114/20
We still need to simplify this answer
We can divide this result into 2/2.
114/20 = 57/10
57/10 is the simplest form. If you were to divide more, you will get involved with decimals.

Add up all data values to get the sum
Count the number of values in your data set
Divide the sum by the count
Answer:
19
Step-by-step explanation:
fore refrence, heres the data from least to greatest, this is important for this question
11, 11, 14, 24, 27, 79
since the points for this set is even (6 points in the data set) we first need to devide it into two groups at the center
11, 11, 14 and 24, 27, 79
then take the two numbers from the inside ends ((in bold)) and find the average between them, since these are the centermost numbers in the full set
14 + 24 = 38
38 / 2 = 19
therefore the median for the dataset is 19

Suppose you have drawn two cards: 10 of clubs and 4 of hearts. You now draw a third card from the remaining 50. What is the probability that the sum of all three cards is strictly larger than 21
The probability that the sum is strictly larger than 21 is P = 0.46
How to find the probability?
We already have a 10 and a 4, so: 10 + 4 = 14
To sum more than 21, we need to draw at least an 8.
On the deck there are:
6 cards equal or larger than 8 of diamonds.6 cards equal or larger than 8 of clubs.6 cards equal or larger than 8 of spades5 cards equal or larger than 8 of hearts (because we already drew the 10).So, 23 out of 50 cards meet our requirements. So the probability will be:
P = 23/50 = 0.46

find the vol of this prism
Answer:
V = 396 cm³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the height of prism )
A = [tex]\frac{1}{2}[/tex] bh ( b is base and h perpendicular height )
here b = 9, h = 8 , then
A = [tex]\frac{1}{2}[/tex] × 9 × 8 = 4.5 × 8 = 36 cm² , so
V = 36 × 11 = 396 cm³

•
B. 2257 units*
• C. 1927 units3
D. 5767 units3
Answer:
192π
Step-by-step explanation:
cylinder volume is base times height
2πr^2 = base = 64π
height = 3
64π*3 = 192π
The volume of the given cylinder is 192π cubic units. Therefore, option C is the correct answer.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
From the given figure, radius of a cylinder = 8 units and radius of a cylinder = 3 units.
We know that, volume of a cylinder is πr²h.
Now, volume = π×8²×3
= π×64×3
= 192π cubic units.
Therefore, option C is the correct answer.

Use the long division method to find the result when x^3+9x² +21x +9 is divided
by x+3
Answer:
x^3 + 9 x^2 + 21 x + 9 = (x^2 + 6 x + 3)×(x + 3) + 0
Step-by-step explanation:
Set up the polynomial long division problem with a division bracket, putting the numerator inside and the denominator on the left:
x + 3 | x^3 | + | 9 x^2 | + | 21 x | + | 9
To eliminate the leading term of the numerator, x^3, multiply x + 3 by x^2 to get x^3 + 3 x^2. Write x^2 on top of the division bracket and subtract x^3 + 3 x^2 from x^3 + 9 x^2 + 21 x + 9 to get 6 x^2 + 21 x + 9:
| | | x^2 | | | |
x + 3 | x^3 | + | 9 x^2 | + | 21 x | + | 9
| -(x^3 | + | 3 x^2) | | | |
| | | 6 x^2 | + | 21 x | + | 9
To eliminate the leading term of the remainder of the previous step, 6 x^2, multiply x + 3 by 6 x to get 6 x^2 + 18 x. Write 6 x on top of the division bracket and subtract 6 x^2 + 18 x from 6 x^2 + 21 x + 9 to get 3 x + 9:
| | | x^2 | + | 6 x | |
x + 3 | x^3 | + | 9 x^2 | + | 21 x | + | 9
| -(x^3 | + | 3 x^2) | | | |
| | | 6 x^2 | + | 21 x | + | 9
| | | -(6 x^2 | + | 18 x) | |
| | | | | 3 x | + | 9
To eliminate the leading term of the remainder of the previous step, 3 x, multiply x + 3 by 3 to get 3 x + 9. Write 3 on top of the division bracket and subtract 3 x + 9 from 3 x + 9 to get 0:
| | | x^2 | + | 6 x | + | 3
x + 3 | x^3 | + | 9 x^2 | + | 21 x | + | 9

| | | -(6 x^2 | + | 18 x) | |
| | | | | 3 x | + | 9
| | | | | -(3 x | + | 9)
| | | | | | | 0
The quotient of (x^3 + 9 x^2 + 21 x + 9)/(x + 3) is the sum of the terms on top of the division bracket. Since the final subtraction step resulted in zero, x + 3 exactly divides x^3 + 9 x^2 + 21 x + 9 and there is no remainder.
