Answer:
the ratio is 2 : 4.7
Step-by-step explanation:
3 times 2.35 equals 7, and 2 times 2.35 equals 4.7
Factor it should be
8(v-8)(v+7)
q + d = 80
.25q + .10d = 14.45
q. + d= 80
25q + 10d = 1445
-10q. - 10d = -800
25q + 10d = 1445
15q. = 645
q = 43 quarters
43 + d = 80
d= 37 dimes
Answer:
79.4 m
Step-by-step explanation:
In this problem we deal with a right triangle with hypotenuse 90 m. We are told that tan Ф = 15/8; 15 represents the vertical distance of the kite off the ground and 8 represents the horizontal distance from the kite flyer to the kite. This is sufficient info from which to determine the angle of elevation from kite flyer to kite: tan Ф = 15/8 yields Ф = 1.08 radians.
Using this same angle Ф = 1.08 radians, sin Ф = (vertical distance) / hypotenuse = sin 1.08 rad = 0.882.
Then the vertical distance (height of the kite) is
(90 m)(0.882) = 79.4 m
