D. 170 pounds

Answers

Answer 1

Answer: number 19

price :$16
pay :10%
ask:each monthly payment
answer:
pay =10%×$160=$16
each monthly payment
={$160-$16}÷6
144÷6
$24
number 20
weight earth:150 pounds
ratio :5:7
weight neptune :7/5×150=210 pounds

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the owner of a small computer repair business has one employee, who is paid an hourly rate of $22. The owner estimates his weekly profit using the function p(x)=8600-22x.

The variable x represents the number of hours the employees. The total payment will be calculated by using the expression below,

p(x)=8600-22x

Hence, the value x is the number of hours employees worked.

This figure shows the nose cone of a rocket used for launching satellites. The nose cone houses the satellite until the satellite is placed in orbit. What is the volume of the nose cone?45 cubic feet
60 cubic feet
90 cubic feet
180 cubic feet

Answers

see the attached figure to better understand the problem

we know that

The volume of the cone is equal to

$V=(1)/(3) \pi r^(2) h$

in this problem

$r=(6)/(2) =3\ ft\n \n h=15\ ft$

Substitute the values in the formula above

$V=(1)/(3)* \pi* 3^(2)* 15\n \n V=45\pi \ ft^(3)$

therefore

the answer is

The volume of the nose cone is $45\pi \ ft^(3)$

The formula to get the volume of a cone is
V = (1/3)πr²h
where V is the volume
r is the radius at the base
h is the height

No values are given but simple substitution should give the correct answer.
