14 000 000 000 cubic meters.
Answer:
4 / 15
Step-by-step explanation:
Fraction that likes stuffed animal = 16/20
4/12 of fraction who like stuffed animals prefer shaggy ones ;
Fraction of second grade that like stuffed shaggy animals ;
4/ 12 of 16/20
(4 /12) * (16 / 20)
(4 * 16) / (12 * 20)
= 64 / 240
= 4 / 15
I don’t even know 5x 15 equals 7 because 12inches is a feet
2. |x|=-7
-x=-7. x=-7
x=7. x=-7
Draw a diagram:
from the top of the hill draw a line 18° above the horizontal to the top of the 30 ft pole.
From the top of the hill we draw a line 14° below horizontal to the bottom of the 30 ft pole.
We now have 2 right triangles sharing a common horizontal line,x, to the pole.
Let y=part of pole above horizontal line
30-y=part of pole below horizontal line.
We shall have the following equations:
y/x=tan 18
30-y/x=tan14
x=y/tan 18
x=(30-y)/tan 14
y/tan 18=(30-y)/tan 14
y tan 14=tan 18(30-y)
ytan 14=30tan 18-ytan18
y tan 14+y tan 18=30tan 18
y(tan 14+tan 18)=30*tan 18
y=(30*tan 18)/(tan 14+tan 18)
x=y/tan 18=30/(tan 14+tan10)=52.2423 ft
thus her distance x from the pole=52.2 ft
