What should the following rate be divided by to convert it to a unit rate?
6 inches
________
12 hours
Answers
Answer:
Unit rate is a rate that has 1 as denominator.
Given the rate: 6 inches / 12 hours, we have to divide numerator and denominator by 12 to transform the denominator in 1, as follows:
\frac{6}{12} = \frac{6/12}{12/12} =
12
6
=
12/12
6/12

No solution. If you rearrange things a bit, you have

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4 °F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation.
Write an expression to represent the submarine’s elevation after its final dive. Then simplify the expression to find its elevation.
Answers
Answer:
-502.5 - 115 = - 617.5
63 1/4 - 2 1/5 =
63 - 2 = 61
1/4 - 1/5 = 5/20 - 4/20 = 1/20
so 63 1/4 - 2 1/5 = 61 1/20
after the sub dove, elevation level is - 617.5 and temp is 61 1/20 F
Step-by-step explanation:
The elevation is 617.5 feet deep and the temperature is [tex]61\dfrac{1}{20}[/tex] F.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The expression for the elevation is,
E = -502.5 - 115
E = - 617.5 feet
The temperature at this elevation is calculated as:-
⇒ 63 ( 1/4 )- 2( 1/5 )
⇒ 63 - 2 = 61
⇒ 1/4 - 1/5
⇒ 5/20 - 4/20
⇒ 1/20
T = 63 (1/4) - 2 ( 1/5 )
T = 61 ( 1/20 ) F
Therefore, the elevation is 617.5 feet deep and the temperature is [tex]61\dfrac{1}{20}[/tex] F.

So to find the y-intercept, you look to see where the point is located when it crosses the y-axis. In this case, it crosses at (0, -2).
To find the slope, you do rise/run. Pick one point to start with. Count upwards, then over. You could also use slope formula if you know two points on the graph: slope= (y2-y1) / (x2-x1)

Chris bought 10.4 gallons of gasoline. There are approximately 3.8 liters in 1 gallon. Which measurement is closest to the number of liters of gasoline Chris bought?
Try and give a good explanation bc I have a test over proportions tomorrow.
Thanks!
Answers
Answer:
395.2
Step-by-step explanation:
104 x 3 .8 = 395.2
Good luck on the test!
we know there are about 3.8 liters in 1 gallon. if Chris bought 10.4 gallons, that’s 10.4 * 3.8 liters
10.4 * 3.8 = 39.52 liters
as a proportion, we can write it as
3.8/1 = x/10.4
(number of liters per number of gallons. there are 3.8 liters per gallon, but we don’t know how many liters in 10.4 gallons yet, thus the x)
then you cross multiply (multiply one sides denominator to with the other sides numerator twice and set them equal)to get
1x = 3.8*10.4
simplify
x = 39.52 liters
