Answer:
60
Step-by-step explanation:
x + 0.30x = 78
1.30x = 78
x = 60
<span>The exact solution of cos (17</span>π<span>/6) is as follows:
First change the angle into degrees.
17(</span>π/6) (180°/π) = 510°
Then we calculate the cosine of the angle above and it as follows:
cos 510° = -(√3)/2
Hope this answers the question. Have a nice day.
Answer:
Step-by-step explanation:
A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a/b or {\displaystyle {\tfrac {a}{b}}}
b
a
, where a and b are both integers. As with other fractions, the denominator (b) cannot be zero.
1,344 square feet / 250 square feet = 5.376 cans of paint
Answer:
Option D
Step-by-step explanation:
Formula to use: V=
b=base of triangle a=altitude of triangle h=height of prism
Doing 
is essentially finding the area of the triangle and after multiplying by h will give you the volume of the triangular prism.
Solve: V = 
or option D
Ps. Altitude is perpendicular or 90 degrees to the side I used for the base, so it wouldn't be option C.
