Step-by-step explanation:
First step is to identify what the problem is asking for and what is given.
9 laps in 28 minutes
Searching for number of laps in 1 hour and 15 min.
1 hour + 15 min. = 75 minutes convert to minutes
9 laps / 28 minutes = x laps / 75 minutes create an equation
9/28 = x/75
9*75 = 28x cross multiply
675 = 28x
x = 675/28 = 24.12 simplify
Melanie can run 24 complete laps in 1 hour and 15 minutes.

Answer:
Step-by-step explanation:
There is a 1/20 chance of getting a 1.
This is a 5% chance.
I would say it's highly unlikely.
If this helped, please mark brainliest :D
Answer:
highly unlikely
Step-by-step explanation:
It's certainly not impossible because there is a 1 on the board. However, the probability of landing on the 1 is 1/20 and since that number is really small, it is highly unlikely.
the value of a baseball card can be represented by the equation y equals 3x + 39 where X represents the number of years that Robert has on the card and why represents the total value in dollars of the card what was the value of the card when Robert originally purchased it $3 $13 $36.39
Answer:
I need the values of either X or Y to solve this. I can solve for what X is though.
Step-by-step explanation:
A: X = -12
B: X =78
C: X = 12.13
I hope this helps you, but since both X and Y are unknown variables, you can't solve it, only simplify (which it already is.)

what is -0.75 - 0.4 simplified
Answer:
= -0.75-0.4
= -1.15
Step By Step
The simplified result of -0.75 - 0.4 is -1.15.
To simplify the expression -0.75 - 0.4
Step 1: Start by subtracting the decimals without considering the signs: 0.75 - 0.4 = 0.35.
Step 2: Now, remember that the original expression had a negative sign in front of it, so the final answer needs to be negative. Since we already calculated a positive value (0.35), we'll make it negative by adding the negative sign: -0.35.
Step 3: Finally, we need to subtract the whole number parts. -0 (whole number part of -0.75) - 0 (whole number part of -0.35) = 0.
Putting it all together, we have -0 - 0.35 = -0.35.
But remember, the original expression had a negative sign, so the final result is -(-0.35), which simplifies to -0.35.
In mathematical terms, -0.75 - 0.4 = -0 - (0.75 - 0.4) = -0 - 0.35 = -0.35.
So, the simplified answer is -0.35, which can also be written as -1.15 (since -0.35 = -1.00 + 0.15).
In summary, when you subtract -0.4 from -0.75, you get -0.35 or -1.15, depending on how you choose to express it.

What is the decimal expansion for 12

A.12.6
B.12.65
C.12.6
D.12.66
pls help me
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

Answer:
53 degree
Step-by-step explanation:
180-127=53.......
Answer:
53
Step-by-step explanation:
Hi,
When two lines add up to 180 degrees, they are said to be supplementary angles. Since we have one angle measurement, all we have to do is subtract it from 180.
180 - 127 = 53
That means the other angle measures 53 degrees.
Hope this helps :)

Answer:
38.88
Step-by-step explanation:
You first calculate the area of the entire skillet which is:
8 × 8 = 64
Then subtract the 64 by the area of both veggies burgers:
64 - 25.12 = 38.88
4 liters of 2% milk contains 8% cholesterol. A container of skim milk contains 2% cholesterol. How many liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol?
To solve this problem, we can set up an equation based on the amount of cholesterol in the mixture.
Let's assume that x liters of skim milk need to be added to the 4 liters of 2% milk.
The amount of cholesterol in the 4 liters of 2% milk is 8% of 4 liters, which can be calculated as (8/100) * 4 = 0.32 liters of cholesterol.
The amount of cholesterol in the x liters of skim milk is 2% of x liters, which can be calculated as (2/100) * x = 0.02x liters of cholesterol.
The total amount of cholesterol in the mixture is the sum of the cholesterol in the 2% milk and the skim milk, which should be equal to 4% of the total volume of the mixture. So, we have:
0.32 + 0.02x = (4/100) * (4 + x)
Simplifying the equation:
0.32 + 0.02x = 0.04(4 + x)
0.32 + 0.02x = 0.16 + 0.04x
0.02x - 0.04x = 0.16 - 0.32
-0.02x = -0.16
Dividing both sides by -0.02:
x = (-0.16) / (-0.02)
x = 8
Therefore, 8 liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol.
To solve this problem, we can use the following equation:
4+x4×8+x×2=4
This equation represents the ratio of the total cholesterol to the total volume of the mixture. The numerator is the sum of the cholesterol from the 2% milk and the skim milk, and the denominator is the sum of the volumes of the 2% milk and the skim milk. The equation is equal to 4 because we want the mixture to have 4% cholesterol.
To find x, we can simplify and solve for x:
4+x32+2x=4
32+2x=16+4x
16=2x
x=8
Therefore, we need to add 8 liters of skim milk to the 4 liters of 2% milk to create a mixture with 4% cholesterol.

Answer:20.7 units²
Step-by-step explanation: volume of a rectangular prism is L×W×H
therefore 82.8=L×W×the height which is 4 units so if u do 4×L×W you get 4LW which is the volume
(4LW=82.8) now divide 82.8 by 4LW to get the value of LW. The value of LW is an area of one of the bases because area is L×W which is basically LW
