Answer:
1) 62.5%
2) 8-x/8=y/100 (where y is the percent)
Step-by-step explanation:
1) so there’s 8 questions in total cause each question si 5 points and 40 points is the max so 40/5=8
write a proportion where 8-3/8=y/100 (it’s 8-3 because it’s total question minus the wrong questions and you’ll get the remaining points and put it over a hundred since the max score you can get is a hundred.
so 5/8= y/100
cross multiply
500=8y
Divide 8 on both sides
you’ll get 62.5
2) Jist use the equation 8-x/8=y/100
( where x is the wrong amount of questions and y is the total percent)
The area (A) of a square is determined by using the formula, A = s² where s is the measure of each side. Given s = 3 ft, the area of the square is
A = (3 ft)² = 9 ft²
Doubling the sides makes them 6 ft. The new area is, A = (6 ft)² = 36 ft². The new area is not double of the previous area but four times. The new area (An)
An = (2s) ² = 4s² = 4A
Answer:X=3
y= -4
Step-by-step explanation:
If we're solving for x or y, then the intercept we're not solving for is equal to zero. Solving for y means x=0, solving for x means y=0.
so solving for x, 4x=12--> x=3, since y=0 in this scenario.
Solving for y, x=0, so -3y=12--> y=(-4)
They are the same line thats what i mean with the same answer
Answer:
Step-by-step explanation:
<u>Find the volume of the box:</u>
- V = lwh
- V = 4 1/2 * 8 * 1/2 = 9/2 * 4 = 18 ft³
Correct choice is D
