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

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

Ralph wants to build a rectangular deck with a predefined area of 792 feet squared. One side of the deck will be 54 feet longer than the other. To find the side lengths, he first writes the equation (x)(x+54)=792 and later simplifies it to (x-12)(x+66)=0, where x is the length of the shorter side. Which of these are the side lengths, in feet, of the rectangular deck? Select all that apply. A. 42 B. 54 C. 12 D. 66 E. 120
Answers
Answer:
C.12 and D.66

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

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.

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.
