Answer:
1st Question
A. 85
2nd Question
B. 71
Step-by-step explanation:
1st Question
{90 + 94 + 96 + 90} = 370/4 = 92.5
{95 + 99} = 194/2 = 97
{87 + 75 + 82 + 85} = 329/4 = 82.25
{71} = 71/1 = 71
.20(92.5) +.25(97) +.30(82.25) +.25(71) = 85.175 Rounded-up = 85

Answer:
363.6
Step-by-step explanation:
Given in the question,
side of square = 10
Step 1
To find the slant height pyramid we will use pythagorus theorem
13² = 5² + height²
height = √13² - 5²
= 12
Now find the height of the pyramid
12² = 5² + height²
height = 10.91
Step 2
Base area of the pyramid
area = l²
= 10²
= 100
Step 3
Volume = 1/3(height)(basearea)
= 1/3(10.91)(100)
= 363.6
