Answer:
58.33333%
Step-by-step explanation:
Exam ≥ 80% Exam < 80%
Studied 4+ hours 18 6
Studied < 4 hours 10 14
The number of students who took the exam is 18+10+6+14 =48
The number of students who got an 80 or above is 18+10 = 28
The percent with 80 or above is 80 or above over total
28/48
.5833333
Answer:
Its 100 percent B
Step-by-step explanation:
first u multiply 3 which will give u 3V on the left side.
then you divide pie times radius squared which will give you 3V divided by pi radius squared equal to H which is the height
The lateral surface area of the cylinder = 80 sq cm.
Step-by-step explanation:
Given,
The circumference of the base of the cylinder is 16 cm
So, 2 X pi X r = 16 cm ( where r be the radius of the base)
Now, the lateral surface of the cylinder = 2 X pi X r X H ( where H be the height = 5 cm)
= 16 X 5 sq cm
= 80 sq cm
Hope it helps you.
It would be A. You can find this out by using SOH CAH TOA,
SOH means sin= opposite/hypotenuse
CAH mean cos= adjacent/hypotenuse
TOA means tangent= opposite/adjacent
You would use CAH since you are trying to find cos∠C
You would have cos∠C=10/26.
26 is the hypotenuse since it is opposite the right angle and is the biggest side.
10 is the adjacent since it is right next to C
You would simplify this down to 5/13 by dividing by 2.
This gives you A.
