Answers

The Value of the expression 2s³ - 4r² by substituting the given values into the expression is 246

Given the equation ; 2s³ - 4r²

Value of r = 1 ; value of s = 5

To solve, substitute the values of r and s into the equation :

2(5)³ - 4(1)²

2(5 × 5 × 5) - 4(1 × 1)

2(125) - 4(1)

250 - 4

= 246

Therefore, the final value of the expression by substituting the value of r and s as 1 and 5 respectively is 246

Sarah is playing a board game. Her score was -275 at the start of her turn. At the end of her turn, her score was -425. What was the change in Sarah's score (in points) from the start of her turn to the end?

Answers

Answer:

150 points

Step-by-step explanation:

Since they are asking for a change, first you need to subtract the greater number by the least number. So the equation now looks like -275 - (-425), solving this using integer skills will get you a answer of 150 points.

Answer: -150

Step-by-step explanation:

The change is obtained by subtracting the original term from the second term so you do -425 + 275 = -150, the change in Sarah’s score.

A rectangular room is 11 feet by 18 feet. The ceilings are 10 feet high. If a gallon of paint covers 250 square feet. How many gallons of paint are needed to paint the room?

Answers

Answer:

2.32 gallons of paint

Step-by-step explanation:

First, find the area of all 4 sides of the room, with the equation A = lw

11(10)

= 110 (for 2 of the walls)

18(10)

= 180 (for the other 2 walls)

Add these up:

110 + 110 + 180 + 180

= 580

Then, divide this by 250:

580/250

= 2.32

So, 2.32 gallons of paint will be needed to paint the room.
