The figure below is made of two identical triangular prisms. What is the volume of the figure?

Answers

Answer:

A triangular prism is 1/2 the volume of a rectangular prism with the same dimensions.

V = BH (Base x Width) of a triangular its 1/2BH

The base is 10 x 5, 50 is the base.

The height is 6, and that would be 300 / 2 since it's triangular so its 150 inches squared for one. Since there are 2.

The total volume is 300 inches squared.

Answer: Q1: D. Distribute 3 through the parenthesis

Step-by-step explanation:

As for the second question, I am not sure how to begin. Sorry

Answer:

For the first question: 3(p - 3) = 2p + 7, the first step would be to distribute 3 to both terms in the parentheses

For the second question:

6n + 11 = -7 + 3n

-3n               -3n

3n + 11 = -7

      -11    -11

3n = -18

3n/3 = -18/3

n = -6

Check:

6(-6) + 11 = -7 + 3(-6)

-36 + 11 = -7 + -18

-25 = -25, since these match n definitely equals -6

Which is the correct classification of the value 7pi?


A-Real, Rational, integer

B-Real, Rational

C-Irrational, Integer

D-Real, Irrational
Please Help Me ; ^;

Answers

Answer: Real, irrational

Step-by-step explanation:

Real because it is an actual measurement. Irrational because π can't be expressed as a fraction. Not an integer because integers are whole numbers.

The correct classification is -Real, Irrational

What is irrational number?

Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0). Also, the decimal expansion of an irrational number is neither terminating nor repeating.

Irrational numbers are real numbers that cannot be represented as a simple fraction. These cannot be expressed in the form of ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers.

Given number: 7* pi

Here, 7 is the real number.

But pi is real but not rational number.

pi is an irrational number.

Hence, the correct classification of 7 pi is Real, Irrational.

Solve the system x+y=0 −2x−y=8 *Answer should be in ( x , y ) form, will give 40 points *

Answers

Answer:

x = -8 and y= 8

(-8,8) is the answer

Answer:

(2,4) (-4,16)

Step-by-step explanation:

Subtract  2 x  from both sides of the equation.

y = 8 − 2 x

Substitute  8 − 2 x  for  y  into  x ^2 − y = 0  then solve for  x .

x = 2 , − 4

Substitute  2  for  x  into  x 2 − y = 0  then solve for  y .

y=4

Substitute  − 4  for  x  into  x 2 − y = 0  then solve for  y .

y=16

Equation form

x = 2 , y = 4

x = − 4 ,  y = 16

A survey found that 12 out of every 15 people prefer eating out over cooking. If 500 people took the survey, how many people prefer eating out?

Answers

Answer:

400 people

Step-by-step explanation:

15 = 12

500 = x

Cross multiply

15x = 12 × 500

Divide both sides by 15

[tex]\frac{15x}{15}[/tex] = [tex]\frac{12 * 500}{15}[/tex]  (* means multiplication if you do not know)

[tex]\frac{12 * 500}{15}[/tex] = 100 × 4= 400 people

Divide 500 by 15 that equals 33.33 then multiply that number by 12 and that equals 399.96 which is then rounded up to 400/500 people prefer eating out rather than cooking at home.
