Answer:
Given,
A=90
b=15
A=12bh
Now,
Step-by-step explanation:
Put the given value in the formula
A=12bh
90=12*15*h
90=180h
90/180=h
Hence, h=0.5
Answer:
180 cm³
Step-by-step explanation:
A glass is 1/3 full. Then 75cm³ of orange juice is poured in. The glass is now 3/4 full. What is the total volume of the glass?
Let
x = total volume of the glass
1/3x + 75 = 3/4x
75 = 3/4x - 1/3x
75 = 9x-4x/12
75 = 5/12x
x = 75 ÷ 5/12
x = 75 × 12/5
= 900/5
= 180 cm³
x = 180 cm³
Answer:
It depends on what operation you are doing
Step-by-step explanation:
in addition its false For Example: -2+(-2)= -4
in subtraction its false For Example -8 - (-2)= -6
in multiplication its true For Example: -8 x -3 = 24
in division its true For Example: -8/-2 = 4
For the answer to the question above asking to f<span>ind the exact value of cos 165 degrees.
The answer to this question is
</span><span>cos 165 = cos (120+45) </span>
<span>= cos120 cos 45 - sin 120 sin 45 </span>
<span>= (-1/2)(sqrt(2)/2) - (sqrt(3)/2)(sqrt(2)/2) </span>
<span>= (-sqrt(2) - sqrt(6))/4
I hope my answer helped you. Have a nice day!</span>
The answer is 216 cm³.
This is because the volume of a cube is worked out by doing
.
being the edge. Therefore, you just have to do
(6 × 6 × 6), which is 216.
