Answer:
1%
Step-by-step explanation:
We need our two numbers to have the same units. Since one number is in cents and the other is in dollars, we should change one of them. It could be either one.
Both numbers in cents:
50/4000
OR, both numbers in dollars:
.50/40.00
Either of these will work. Divide, you will get a decimal answer. Then multiply by 100 to change to a percent.
50÷4000 (OR .5/40)
= 0.0125
times by 100
0.0125 × 100
= 1.25% but the directions said to round to the nearest whole number, that's 1%
So the formula for this is for every inch of width, you multiply by 2 to get the length.
Here, I made a table for it.
2×2=4
4×2=8
7×2=14
8×2=16 or 16÷2=8
Answer:
The price of one gallon of gasoline is $3.15
Step-by-step explanation:
If the lady buys 2.4 gallons of gasoline for a total of $7.56, then as the problem suggests, one can find the unknown price of gasoline per gallon (p) by solving the equation for the unknown "p":
2.4 p = 7.56
then divide both sides by 2.4 to isolate the unknown "" on one side of the equal sign:
p = 7.56/2.4
p = $3.15
so this is the price per gallon of gasoline.
Find the mean of the first four test scores first.
(Add all numbers in set and divide by how many numbers there are)
81 + 87 + 71 + 89 = 328 / 4 = 82
Then, find the mean with the 85 added as the fifth term.
81 + 87 + 71 + 89 + 85 = 413 / 5 = 82.6
The impact that the 85 had on the mean test score was that the mean/average increased by 0.6.
