it is -12.5°C outside when the temperature starts increasing by 2.5°C each hour. How long will it take for the temperature to reach -5°C?
Answer: 3 hours
Step-by-step explanation:
The span between -12.5 and -5 is 7.5. Divide that by 2.5 (since that’s the change) and that’ll give you the amount of time it takes.

Jeremy has hit 5 home runs so
far this season. This represents
20% of his yearly goal. How many
more homeruns does he need to hit
to achieve his goal?
Answer:
20 home runs left to hit.
Step-by-step explanation:
Ok so 100%/20% is 5. Increment 5 home runs until you get to 100%. So, 20% =5, 40% = 10, 80% = 15, and 100% = 20
Answer: 25 home runs
Step-by-step explanation:
20% = 5
40% = 10
80% = 20
80% + 20% = 100%
5+10=25

What was the total amount of water in the tank before it was drained
450 gallons
510 gallons
560 gallons
570 gallons
Total amount of water before it was drained will be 510 gallons.
What is rate?"It is a ratio in which the two terms being compared have different units."
For given question,
We have been given a table for the number of gallons of water left in the tank after being drained for two amounts of time.
First we find the rate at which the water was drained from the tank.
[tex]r=\frac{450-330}{30-10}\\\\ r=\frac{120}{20}\\\\ r=6~gallons~per~minutes[/tex]
Let the amount of water in the tank before it was drained = 'x' gallons
And the initial time = 0
Using the rate formula,
[tex]r=\frac{x-450}{10-0}\\\\ 6=\frac{x-450}{10}\\\\ 60=x-450\\\\x=450+60\\\\x=510~gallons[/tex]
Therefore, total amount of water before it was drained will be 510 gallons.

The aspect ratio, the ratio of the width to the height, of various computer monitors is listed in the table below.
Answer: Monitor C is the different one.
Step-by-step explanation:
The aspect ratio is the relationship between width and height.
So we only need to see the quotients between width and height for each monitor and see which quotient is different.
Monitor A:
Quotient = 1152/864 = 1.333....
Monitor B:
Quotient = 800/600 = 1.333...
Monitor C:
Quotient = 1920/1080 = 1.777...
Monitor D:
Quotient = 1600/1200 = 1.333...
We can see that the one with a different aspect ratio is monitor C.
Joe would like to paint a rectangular shaped wall. The measures of dimensions of the wall are 8 inches by 4 inches. Every 1 inch represents 3 feet of the actual wall. If the cost of the painting is $2.50 per square feet, find the total cost of paint needed for the entire wall.
Answer:
$90
Step-by-step explanation:
8 + 4 = 12
12 x 3 (3 feet for each inch) = 36
36 x 2.50 (cost per square foot) = $90
Answer:
$240
Step-by-step explanation:
8 x 4 is 32
32 x 3 is 96
96 x 2.5 is 240

Answer:
x = 20
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )
x = [tex]\sqrt{400}[/tex] = 20

Function 1 is defined by the equation y = -2t + 6
Function 2 is defined by line h, shown on the following graph.
Which function has a more negative slope?
Choose 1 answer:
A. Function 1
B. Function 2
C. The functions have the same slope
Answer:
FUNCTION A
Step-by-step explanation:
It said it was right on khan
Function 1 have more negative slope.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Function 1 is defined by the equation y = -2t + 6
Function 2:
Slope = 4/ 4 = 1
Then, the equation would be
y - 0 = 1( t- 4)
y= t - 4
Hence, Function 1 have more negative slope.
