The correct answer is B. If Alina’s workout was 80 minutes, and Dane’s workout was 48 minutes, they spent the same amount of time on cardio exercise.
To figure this out, first find 15% of 80 and then 25% of 48.
To find 15% of 80, you can first find 10% of 80 which is 8(just move the decimal one place to the left). The remaining 5% will be half of 8 since 8 is 10%. Add both the numbers up and you will get 12. (8+4=12)
To find 25% of 48, you can divide 48 by 4. Since percent means 'out of 100', 25% is 25 of 100. 100 divided by 25 is equal to 4. So, 48 divided by 4 is equal to 12.
So, the final answer is B. They both equal to 12.
Hope it helps :)
Answer:
The answer to your question is letter C
Step-by-step explanation:
This is a problem with the inverse rule of three because we expect that more machines can complete the same work in fewer days.
6 machines ------------------ 12 days
x machines ------------------- 8 days
x machines = 
x = 4 machines
Answer:
W = 73°
X = 81°
Y = 26°
Step-by-step explanation:
We can let W, X, Y represent the measures of the corresponding angles. The problem statement gives us the relations ...
W = 3Y -5
X = W +8
Of course, the sum of angles in a triangle is 180°, so we have ...
W +X +Y = 180
W +(W +8) +Y = 180 . . . . . substitute for x
2W +Y = 172 . . . . . . . . . subtract 8, collect terms
2(3Y -5) +Y = 172 . . . substitute for W
7Y = 182 . . . . . . . . add 10, collect terms
Y = 26 . . . . . . . . divide by 7
W = 3(26) -5 = 73
X = 73 +8 = 81
The angle measures are (W, X, Y) = (73°, 81°, 26°).

Answer:
Slope = -4 y-intercept = 3
Step-by-step explanation:
start with 4x + y = 3
Rearrange so it fits y= mx+b equation (subtract 4x off each side)
So new equation looks like this:
y= -4x + 3
from this we can see that the slope is -4 and the y-intercept is 3.
