The minutes taken by Grayson to text 140 words if Grayson can text 70 words in 4 minutes is 8 min.
<h3>What is division?</h3>
It is the basic arithmetic operation, in which you are separating the number into some parts.
Given:
Grayson can text 70 words in 4 minutes,
The time is taken to type one word = 4 / 70 = 0.057 min
Thus, typing 140 words Grayson would take = 0.057 × 140 = 8 min
Therefore, the minutes taken Grayson to text 140 words if Grayson can text 70 words in 4 minutes is 8 min.

Step-by-step explanation:
10 divided by 4 is 25, so 25 in one week
Assuming angle a and angle b are not equal and the given triangle is a right triangle .
Let's see cos(90-b)
Here we use the formula of cos(A-B)=cos A cos B -sin A sin B
And on using this formula,we will get
cos(90-b)= cos 90 cos b + sin 90 sin b
Value of cos 90 = 0 and sin 90 =1 , And on using these values, we will get
cos(90-b) = (0) cos (b) + (1) sin (b)
cos(90-b) = 0 + sin (b)
cos(90-b) =sin(b)
As we see that on using the formula, we are getting cos(90-b)= sin b .
So the correct option is cos(90-b)= sin b
