Answer:
266 miles
Step-by-step explanation:
Given statement
4 hours and 45 minutesClearly, 45 is 3/4th of an hour. Thus, this statement can also be written as:
⇒ 4 hours and 3(Hour)/4 minutes⇒ 4 hours + 3(Hour)/4 minutes⇒ 4 hours + 0.75(Hour)⇒ 4.75 hoursWe are given that:
56 miles per hourWhen we convert this statement into an equation, we get:
⇒ 56 miles = 1 hourMultiply both sides by 4.75 to obtain the distance in 4.75 hours.
⇒ 56 × 4.75 miles = 1 hour × 4.75⇒ 266 miles = 4.75 hourssally was playing checkers with a friend. The ratio of games sally won to lost was 9 : 5 if sally won 36 games, how many games did her friend win?

Multiply the following numbers.
(-7)(-5) =
And why???
Answer: 35
Step-by-step explanation: The reason is that 7 × 5 = 35 and when you multiply two negative numbers they make the answer positive. I hope this helped!
Answer:
35
Step-by-step explanation:
7 times 5 equals 35. Even though the two numbers are positive, the product will be negative, because a negative times a negative equals a positive. A negative times a negative will equal a positive because what was originally negative has been reversed in direction.
So, the answer is 35.

Mary swam 3/4 mile each day for 8 days
Step-by-step explanation:
I'm assuming the question is how many miles in total did mary swim.
if this is the case then we just multiply the number of days by the number of miles per day.
Hence,
3/4 × 8 = 6
so 6 miles in total.

In 1977, the price of a scientific
calculator was $175. In 2004, the
price was $15. Assuming the change
in price was linear, what was the
approximate price of a scientific
calculator in 1998?
First, we need to find how many years are in between 1977 and 2004:
2004-1977 = 27
And the different between the prices:
175-15 = $160
Since this is supposed to be linear, we can do 160/27 which is about 5.925.
We can round this out to be about $6 cheaper per year, or $5.90.
Deshaun needs 3000 for a future project. He can invest 2000 now at an annual rate of 9.5%, compounded semiannually. Assuming that no withdrawals are made, how long will it take for him to have enough money for his project? Do not round any intermediate computations, and round your answer to the nearest hundredth.
[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill &\$3000\\ P=\textit{original amount deposited}\dotfill &\$2000\\ r=rate\to 9.5\%\to \frac{9.5}{100}\dotfill &0.095\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{semiannually, thus twice} \end{array}\dotfill &2\\ t=years \end{cases}[/tex]

A spinner has 18 equal-sized sectors labeled 1 through 18. The spinner is spun once.
What is the probability that the spinner lands on an even number or a number greater than 10?
1/2 4/9 11/18 13/18
Answer:
2/9
Step-by-step explanation:
12,14,16,18 are all greater than 10, which is 4/18 numbers, simplified as 2/9
Answer: 13/18
Step-by-step explanation:
First you add up the amount of even numbers and the amount of numbers greater than 10
2,4,6,8,10 make 5 then add 8 more for 11-18, leaving you with 13 then take 13 and divide it by the total (18) and you will get 0.72 or 13/18

Answer:
57/40
Step-by-step explanation:
So we need to find the LCD, or the least common denominator. The LCD is 40. Now, we do a transition to find the new numerator.
[tex]\frac{4}{5} =\frac{x}{40} \\\\\\frac{5}{8} = \frac{x}{40}[/tex]
The new equation is this:
[tex]\frac{32}{40} +\frac{25}{40}[/tex]
Now we use our common sense. 32+25=57
57/40.

Algebra 1.
13. Write a system of linear equations that has the ordered pair (3, -5) as its solution.
Answer:
[tex]x + y = -2\\x-y=8[/tex]
Step-by-step explanation:
3 is the [tex]x[/tex], and -5 is the [tex]y[/tex].
1) Create two equations that add and subtract them.
[tex]x + y = -2\\x-y=8[/tex]
2) Check whether you get the same answer (3,-5) or not. To do so, you need to solve them simultaneously using the elimination or substitution method. I will demonstrate using the substitution method.
[tex]x = -2 - y\\x-y=8\\(-2 - y) -y =8\\-2-2y=8\\-2y = 8 + 2\\-2y = 10\\y = \frac{10}{-2} \\y = -5[/tex]
To find [tex]x[/tex], substitute the result into one of the two equations. I choose [tex]x+y=-2[/tex].
[tex]x-5=-2\\x = -2 +5\\x = 3[/tex]

8. When solving the equation (2 - x)(x + 1) = 11, Priya graphs y=(2 - x)(x + 1) - 11 and then looks to find where the graph crosses the x-axis.
Tyler looks at her work and says that graphing is unnecessary and Priya can set up the equations 2 - x = 11 and x + 1 = 11, the solutions
are x = -9 or x = 10.
A) Do you agree with Tyler?
yes
no
Answer:
No
Step-by-step explanation:
Tyler is incorrect. The only way you can set individual terms equal to the result is when the result is zero. This is due to zero times anything equalling zero. If one of the terms equals zero, then the other term does not matter because the whole thing will be zero. Let's say:
[tex](2 - x)(x + 1) = 0[/tex]
If the first term equals zero, the entire left side is zero. For Priya's case, the right side is not zero, it is 11. If one term is 11, the other term will contribute. You can check this by plugging in Tyler's solutions. The correct way to solve this equation is to use FOIL on the two terms, then subtract 11 on both sides to get zero. Then use the quadratic formula.
if you were to flip the coin 15, how many times will the coin land on tails based on experimental probability? jordan flipped a count of 45 times.His result are below: heads: 24 tails: 21
Answer:
It will land 7.5 times on tails, which is rounded up to 8 times
Step-by-step explanation:
there are 2 possibilities, heads or tails
so you divide 15 in 2 and get 7.5
The coin will land 7 times tail based on the experimental probability.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
When the coin tossed 45 times.
Head= 24, tail = 21
So, fraction of appearing tail will be
= 21 / 45
= 0.466667
Now, if the coin tossed 15 times then the coin land on tails
= 15 x 0.466667
= 7

Answer:
[tex]\sf y=3x+2[/tex]
Step-by-step explanation:

(where m is the slope and (x₁, y₁) is a point on the line)
Given:
slope (m) = 3point (x₁, y₁) = (5, 17)Substituting given values into the equation to find the equation of the line:
[tex]\implies \sf y-17=3(x-5)[/tex]

New Berlin Corporation has annual fixed costs of $800,000, variable costs of $48 per unit, and a contribution margin ratio of 40 percent.
a. Compute the unit sales price and unit contribution margin for the above product.
b. Compute the sales volume in units required for New Berlin Corporation to earn an operating income of $600,000.
c. Compute the dollar sales volume required for New Berlin Corporation to earn an operating income of $600,000.
Based on the variable costs and contribution margin, the unit sales price is $80 and the unit contribution margin is $32.
The sales volume in units needed to earn $600,000 is 43,750 units and the amount in dollar sales needed is $3,500,000.
What is the unit sales price and unit contribution margin?The unit sales price can be found as:
= Variable cost / (1 - contribution margin ratio)
= 48 / (1 - 40%)
= $80
Unit contribution margin is:
= Selling price x Contribution margin ratio
= 80 x 40%
= $32
In units, this amount is:
= (Fixed cost + income required) / Contribution margin
= (800,000 + 600,000) / 32
= 43,750 units
In dollar terms the amount needed is:
= Units needed x selling price
= 43,750 x 80
= $3,500,000

well, if you remember P.E.M.D.A.S, which is the order for doing equations, the first two dont matter, but from M for Multiplication, D for Division, A for addition, and finally S for Subtraction, those are the ones that you need here. So you divide the 9s first giving you 9-1+9-1=8+8=16.
