Answer:
it is 55% of 80
Step-by-step explanation:
Hey there!
If she missed 4 problems, and that took off 20%, that means 4 is 20% of the total items.
20% is the same as 1/5 of the total amount, since there are 5 20s in 100.
So, we can simply multiply 4 by 5 to get the total amount of problems.
4 x 5 = 20
This means there were 20 problems on the test.
Hope this helps!
2(4*3) + 5.7*3 + 2(5.7*4)= 86.7 mm^2 (i could be wrong)
Answer:
f(x) = 1/4x +2
Step-by-step explanation:
The y-intercept formula is y = mx + b. b is the y-intercept. The line crosses the y-axis at 2, so the y-intercept is 2. m is the slope and it is rise/run (rise over run). It rises (from the y-axis) once and runs 4 times. Therefore, the slope is 1/4. The equation is f(x) = 1/4x +2.
I think option b is right correct
