Answer:
x =48.6
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp side / hypotenuse
sin x = 54 /72
Taking the inverse sin of each side
sin ^ -1( sin x) =sin ^-1 ( 54/72)
x = 48.59037789
To the nearest tenth
x =48.6
The volume of a right circular cylinder is V=πr²*h
V=π*2*2*h=100π
h=25cm
Answer:
<u>In 14 years Marc's grandmother will be 5 times as Marc will be then</u>
Step-by-step explanation:
1. Information given to us to solve the problem:
Marc's age today = 0
Marc's grandmother age today = 56
2. In how many years will Marc's grandmother be 5 times as Marc will be then?
x = Number of years when Marc's grandmother age will be 5 times as Marc will be then
Let's solve for x, this way:
5 times Marc age in x years = Marc's grandmother age in x years
5 (0 + x) = 56 + x
5x = 56 + x
5x - x = 56 (Subtracting x at both sides)
4x = 56
x = 56/4
<u>x = 14</u>
Let's prove that x = 14 is correct:
5 (0 + 14) = 56 + 14
70 = 70
We proved that x = 14 is correct
<u>In 14 years Marc's grandmother will be 5 times as Marc will be then</u>
