Answer:

1. 90

2.60

3.30

4. 40

5. 80

6. 60

7. 30

8. 30

9. 120

Total for all triangles=180

Step-by-step explanation:

In all the problems, you have to solve for y. This can be done because the three angles are supplementary For example, in the first diagram, you have:

3y+2y+y=180

6y=180

y=30

It's fairly easy to solve from there. Just more multiplying and subtracting.

Carmen is considering joining one of the two movie clubs. Movie Galore charges a monthly membership fee of $10, plus $0.50 per m

lakkis [162]

25 movies.

So basically you start and end at 1 month so,

Galore Cost =
$10
Galore Per Movie =
0.5 x 25 = 12.5 + 10 = $22,5

Cinephile Cost =
$15
Cinephile Per Movie =
0.25 x 25 = 6.25 + 15 = 21.25

These questions are just trial and error

Which of the following equations describe the line shown below?

frez [133]

Here, Slope (m) = y2 - y1 / x2 - x1
m = 10 - 2 / 1 - (-3)
m = 8 / 4
m = 2

y - 10 = 2 (x - 1)
Also, y - 2 = 2(x + 3)

In short, Your Answers would be A & B

Hope this helps!

Please help me answer I need this question right, one more wrong answer and I'll fail

Shkiper50 [21]

Answer: The second option.

Step-by-step explanation:

1. Calculate the first volume assuming that the figure is completed (with no missing part). Therefore, you must apply the formula for calculate the volume of a square prism:

$V_A=s^{2}*h$

Where s is the side of the base and h is the height.

2. Then:

$V_A=(40cm)^{2}*50cm=80,000cm^{3}$

4. The volume of the missing part is calculated with the formula of a rectangular prism:

$V_B=l*w*h$

Where l is the lenght, w is the width and h is the height. Then:

$V_B=(40cm)(40cm-35cm)(50cm-25cm)=5,000cm^{3}$

5. Therefore, you must subtract both volumes to obtained the volume of the figure:

$V_f=80,000cm^{3}-5,000cm^{3}=75,000cm^{3}$

Solve the following using the elimination or substitution method. Show all work.

Jim has 28 nickels and 37 dimes in his pocket. which is determined by the substitution method.

<h3>What is the equation?</h3>

The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.

Let the number of nickels would be n

Let the number of dimes would be d

As per the given question,

d + n = 65 ....(i)

0.10d + 0.05n = 5.10 ....(ii)

From equation (i),

d + n = 65

d + n - n = 65 - n

d = 65 - n

Substitute in for the equation(ii): d = 65 - n

0.10(65 - n) + 0.05n = 5.10

6.5 - 0.10n + 0.05n = 5.10

6.5 - 0.05n = 5.10

6.5 - 0.05n - 6.5 = 5.10 - 6.5

- 0.05n = -1.4

n = 28

This means there are 28 nickels

Substitute the value of n = 28 in the equation (i),

d + n = 65

d + 28 = 65

d = 37

So there are 37 dimes

Thus, Jim has 28 nickels and 37 dimes in his pocket.
