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?
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?
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.

What is not a description of slope?
rise over run
the rate of change of a line
change in y over the change in x
the ratio of horizontal change compared to vertical change
Answer:
Option (d) is wrong.
Step-by-step explanation:
Slope is:
rise over runThe rate of change of a lineChange in y over the change in xThe ratio of vertical change to the horizontal change.It can be given by mathematically as follows :
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{and}\\\\m=\dfrac{dy}{dx}[/tex]
Hence, the option which is not a description of slope is (d) "the ratio of horizontal change compared to vertical change"

The algebraic expression for the given statement is k-13.
The given statement is "15 less than the sum of k and 2".
We need to form the algebraic expression for the given statement.
What is the algebraic expression?In mathematics, an algebraic expression is an expression built up from integer constants, variables, and algebraic operations.
Now, the sum of k and 2=k+2
15 less than the sum of k and 2=(k+2)-15
=k+2-15
=k-13
Therefore, the algebraic expression for the given statement is k-13.
