Answer:
D
Step-by-step explanation:
6% of 40 is 2.4, 40.00+ 2.40=42.40
12%
40% = 0.4
30 = 0.3
0.3 x 0.4 = 0.12
0.12 = 12%
75-25=50
50/75= 66.67% decrease
Answer:
The answer to your question is below
Step-by-step explanation:
1) The triangles are similar by the AA postulate so use proportions to find x.
x/207 = 170/90
solve for x
x = 207(170/90)
x = 207(1.89)
x = 391 ft
2) These triangles are similar so use proportions to solve it
x/138 = (x + 60)/207
207x = 138(x + 60)
207x = 138x + 8280
207x - 138x = 8280
69x = 8280
x = 8280/69
x = 120
Answer:
146.7
Step-by-step explanation:
The equation for finding the volume of a pyramid is
.
For this pyramid, the height is 8, the width is 5, and the length is 11.
=146.67
146.67 rounded to the nearest tenth = 146.7.
