6x-3y=18
3y=6x-18 <em>(Divide each term by 3)</em>
y=2x-6
Step-by-step explanation:
0.48 is the decimal form of 12/25
So,
The formula for the area of a rectangle is:
A = l * w
We will consider l to be the height.
Substitute the given values.
30 = 10 * w or 10w
Divide both sides by 10.
3 = w
The length (I would call it the width, since it is shorter) of the rectangle is 3 centimeters.
Answer:
Step-by-step explanation:
The perpendicular is equal to 6. That's because the left triangle's missing angle is 180 - 45 -90 = 45
The angle in the right triangle is given as 52.
The cos(52) = adjacent side (which we just found to be 6) / y
Multiply both sides by y
y cos(52) = 6
cos(52) = 0.6157
Divide by sides by cos(52)
y = 6 / cos(52)
y = 6 / 0.6157
y = 9.76
