Bryan reads for x minutes. kelly reads for one-fourth the amount of time bryan reads. which statement explains why 14x14x and 0.

25x can each find the number of minutes kelly reads? dividing by four is the same as multiplying by 25%. the expressions are not equivalent. multiplying by 4 is the same as multiplying by 25%. the fraction 1414 is equivalent to the decimal 0.75. therefore, 14x14x can be rewritten as 0.75x.

I think the correct answer from the choices listed above is the second option. The best statement that explains why 14x14x and 0.25x can each find thenumber of minutes kelly reads would be that the expressions are not equivalent. Hope this helps. Have a nice day.

Tan theta is equal to 2- cos theta find the value of sin theta​
artcher [175]

Answer:

sqrt(2)/2

Step-by-step explanation:

Given tan(x)=2-cot(x), find sin(x).

Rewrite in terms of sine and cosine:

sin(x)/cos(x)=2-cos(x)/sin(x)

Multiply both sides by cos(x)sin(x):

sin^2(x)=2sin(x)cos(x)-cos^2(x)

Rewrite cos^2(x) using the identity sin^2(x)+cos^2(x)=1:

sin^2(x)=2sin(x)cos(x)-(1-sin^2(x))

Distribute:

sin^2(x)=2sin(x)cos(x)-1+sin^2(x)

Subtracting sin^2(x) on both sides:

0=2sin(x)cos(x)-1

Add 1 on both sides:

1=2sin(x)cos(x)

Use identity sin(2x)=2sin(x)cos(x) to rewrite right:

1=sin(2x)

Since sin(pi/2)=1, then 2x=pi/2.

Dividing both sides by 2 gives x=pi/4.

So sin(pi/4)=sqrt(2)/2
