How many times does 1/4 go into 9/16
Monica [59]

Answer as a fraction = 9/4

Answer in decimal form = 2.25

================================================

Explanation:

1/4 = 4/16 after multiplying top and bottom by 4

We have some number x such that

(4/16)x = 9/16

we can multiply both sides by 16 to clear out the fractions, getting 4x = 9

Then we divide both sides by 4 to get x = 9/4 = 2.25

The value pi/24 is a solution for the equation 4 cos^4 (4x)-3
MatroZZZ [7]

Answer:

False

Step-by-step explanation:

4 cos^4 (4x)-3 = 0

Substitute into the equation

4 cos^4 (4pi/24)-3 = 0

4 cos^4 (pi/6)-3 = 0

Take the cos pi/6

4 ( sqrt(3)/2) ^4 -3 =0

Take it to the 4th power

4 ( 9/16) -3 =0

9/4 -3 =0

9/4 - 12/4 = 0

-3/4 =0

False
