Answers

It is A. 2x+5

Bill is twice as old as Sharon, making it 2x.

Jason is 5 years older than Bill, making it 2x+5

(It can also be B. because 2x+5 and x2+5 are the same thing)

The non-profit organization you volunteer for is throwing a fundraiser cookout. You are in charge of buying the hamburgers, which cost $3 per pound, and hot dogs, which cost $2 per pound. The meat budget you are given totals $600 dollars. The inequality 3x + 2y less than or equal to 600 represents the possible combinations of pounds of hamburgers (x) and hot dogs (y) you can buy.

Answers

Which of the following represents a solution to the inequality?
200 pounds of hamburgers and 140 pounds of hot dogs
150 pounds of hamburgers and 60 pounds of hot dogs
100 pounds of hamburgers and 240 pounds of hot dogs
240 pounds of hamburgers and 40 pounds of hot dogs

x = hamburger ; y = hot dog
3x + 2x < 600

3(200) + 2(140) = 600 + 280 = 880 No.
3(150) + 2(60) = 450 + 120 = 570 YES.
3(100) + 2(240) = 300 + 480 = 780 No.
3(240) + 2(40) = 720 + 80 = 800 No.

150 pounds of hamburgers and 60 pounds of hot dogs

Answer:

$150$ pounds of hamburgers and $60$ pounds of hot dogs

Step-by-step explanation:

The options are

Which of the following represents a solution to the inequality?

$200$ pounds of hamburgers and $140$ pounds of hot dogs

$150$ pounds of hamburgers and $60$ pounds of hot dogs

$100$ pounds of hamburgers and $240$ pounds of hot dogs

$240$ pounds of hamburgers and $40$ pounds of hot dogs

Let

x------> the pounds of hamburgers

y------> the pounds of of hot dogs

we know that

The inequality that represent the situation is equal to

$3x+2y\leq 600$

Remember that

If a ordered pair is a solution of the inequality

then

the ordered pair must satisfy the inequality

Verify each case

case A) $200$ pounds of hamburgers and $140$ pounds of hot dogs

Substitute the value of x and the value of y in the inequality and then compare

$3(200)+2(140)\leq 600$

$880\leq 600$ ------> is not true

therefore

the case A) is not a solution

case B) $150$ pounds of hamburgers and $60$ pounds of hot dogs

Substitute the value of x and the value of y in the inequality and then compare

$3(150)+2(60)\leq 600$

$570\leq 600$ ------> is true

therefore

the case B) is a solution

case C) $100$ pounds of hamburgers and $240$ pounds of hot dogs

Substitute the value of x and the value of y in the inequality and then compare

$3(100)+2(240)\leq 600$

$780\leq 600$ ------> is not true

therefore

the case C) is not a solution

case D) $240$ pounds of hamburgers and $40$ pounds of hot dogs

Substitute the value of x and the value of y in the inequality and then compare

$3(240)+2(40)\leq 600$

$800\leq 600$ ------> is not true

therefore

the case D) is not a solution

A building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18π meters.What is the area A of the cross section of the column?
Give your answer in terms of pi.

Answers

Answer:

$A=81\pi\ m^(2)$

Step-by-step explanation:

Step 1

Find the radius of the circular cross section

we know that

The circumference is equal to

$C=2\pi r$

we have

$C=18\pi\ m$

substitute and solve for r

$18\pi=2\pi r$

simplify

$18=2 r$

$r=9\ m$

Step 2

Find the area of the circular cross section

The area of the circle is equal to

$A=\pi r^(2)$

we have

$r=9\ m$

substitute

$A=\pi (9)^(2)$

$A=81\pi\ m^(2)$

How many gallons of water will it take to fill a tank measuring 8' long 28" wide and 3' deep

Answers

You're looking for the volume function here. V=LWH

In this case the length is 8 feet
L=8
Width is 28 inches, and since there's twelve inches in a foot, it's 28/12 feet
W=28/12=2 $(1)/(3)$
Height, or in this case depth, is 3 feet
H=3

V=LWH
V=(8)(2 $(1)/(3)$ )(3)
V=56ft $^(3)$

Now you know how many cubic feet are in your tank. There are just around 7.5 gallons in a cubic foot. An estimated answer then would be the volume times 7.5

56·7.5=420

There's an estimated answer. If you need exact EXACT, then using the exact amounts and everything the answer comes out to 418.909 gallons.
