Find the missing value to the nearest hundredth. cos ? = 2/5

Step-by-step explanation:

Let x represent the missing value for our given equation.

We have been given an equation . We are asked to find the missing value for our given equation.

Now, we will solve for x using arccos as:

Upon rounding our answer to nearest hundredth, we will get:

Therefore, the missing value for our given expression would be .

answer: y=4000x+14000

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
