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

.10(95) +.20(80) +.50(67) +.20(60) = 71
Answer:
1. C - 8x bigger
2. D - 16x bigger
3. A - 3x bigger
Step-by-step explanation:
It equals 9.33
because 3 1/2 is 3.5 and 2 2/6 is 2.66 we multiply and get our answer
Answer:
I am pretty sure it's −2.7710843373
A^2 + 2AB + B^2 = (A + B)^2 ==>
16X^2 + 40X + 25 =
= (4X)^2 + 2*4*5X + 5^2 =
= (4X + 5)^2
