Answer: He must have atleast 98 points on the next exam in order to get an average of 92 points.
Step-by-step explanation: To calculate average, you need to add all the numbers given, and divide the sum by how many numbers there are. 87 + 89 + 94 + 98 (equals 368), and divide 368 by 4. You will get the average of 92 as its result.
Th square root of 25 is, 5
Answer:
110.9
Explanation:
Find the height of the triangle by using the Pythagorean theorem.
a^2 + b^2 =c^2
(16/2)^2 + b^2 =c^2
b^2= 192
b or height = 13.86
Area of triangle = (b*h)/2
Area of triangle = (16*13.86)/2
Area of triangle = 110.9
Since volume = l×w×h
so =4 1/3×2 1/2×2 /2
then first change them into improper fraction = 13/3×5/2×5/2
then multiply all the numerators and denominators together= 325÷12
= 325÷12
=27 1/12
hope i helped
-2 *2(4) = -2 *8 = -16
(-2) *2(4) = -2 *8 = -16
-4(2)*2 = -8*2 = -16
-2*(-2*4) = -2 *-8 = 16
D is the only one that is positive so D is the answer
