Answer:

There are 16 multiple choices and 6 short answers.

Step-by-step explanation:

Let the number of multiple choice questions be x and the number of short answer questions be y.

x + y = 22 (total number of questions)

4x + 6y = 100 (total number of points)

x = 22 - y

4(22 - y) + 6y = 100

88 - 4y + 6y = 100

2y = 100 - 88

y = 6

x + 6 = 22

x = 16

Hence, there are 16 multiple choices and 6 short answers.

Hope this helped!

9. Evaluate the function for x = 3.5 *<br> (1 Point)<br> f (x) = 12.5x]<br> A. 8.75<br> B. 8<br> C.9
musickatia [10]

Answer: A. 8.75

Step-by-step explanation: y=12.5x

Step 1: Flip the equation.

12.5x=y

Step 2: Divide both sides by 12.5.

12.5x/12.5=y/12.5 x=8

The answer was 0.8, but I moved the decimal over and it was 80% I simplified it to 8.75

Elena knows dad 5 servings and granola has 1750 calories how many calories are in one serving of granola
aalyn [17]

If you have information about 5 servings, assuming that all servings have the same calories, the information about one serving is simply obtained by dividing the total by 5.

So, each serving has

\dfrac{1750}{5} = 350

calories

During a figure skating routine, Jackie and Peter skate apart with and angle of 15 degrees between them. Jackie skates for 5 met
Xelga [282]

Answer:

The skaters are 2.5 feet apart

Step-by-step explanation:

Firstly, please check attachment for diagrammatic representation.

To calculate the distance apart, this is same as the length PJ

To calculate this length, we can use the cosine rule as follows;

O^2 = P^2 + J^2 -2(P)(J)Cos 15

O^2 = 7^2 + 5^2 -2(7)(5)Cos 15

O^2 = 49 + 25 - 70Cos15

O^2 = 74 - 67.61

O^2 = 6.39

O = √6.39

O = 2.53

O = 2.5 feet to the nearest tenth of a foot

A car traveling at a certain speed will travel 76 feet per second. How many miles will the car travel in 3.1 hours if it maintai
liubo4ka [24]
Keeping in mind that, there are 5280 feet in 1 mile, and 60 minutes in an hour and 60 seconds in each minute, thus 60*60 seconds in an hour, or 3600 seconds.

\bf \cfrac{76~\underline{feet}}{\underline{sec}}\cdot \cfrac{mile}{5280~\underline{feet}}\cdot \cfrac{3600~\underline{sec}}{hr}\implies \cfrac{76\cdot 3600~mile}{5280~hr}&#10;\\\\\\&#10;\cfrac{570~mile}{11~hr}\approx 51.\overline{81}\frac{mile}{hr}\\\\&#10;-------------------------------\\\\&#10;\textit{how many miles does it do in 3.1hrs?}\quad \cfrac{570}{11}\cdot 3.1

What is the greatest common factor of the terms of the polynomial below? 8x^4 - 12x^3 + 20x^2
Daniel [21]

Answer: I think the greatest common factor is 4x^2

Step-by-step explanation:

Find the numerical common factors. Which are 8, -12, and 20. Find the variable common factors for x^4, x^3, and x^2. Multiply them together. Then break down the factors on both sides and pick the biggest one. Finally multiply them together. (I’m sorry, I’m very bad at explaining things.)
