The measure of b is?

35.228

Step-by-step explanation:

b=21

Step-by-step explanation:

For this problem we need to use Pythagorean theorem (a^2+b^2=c^2):

20^2+b^2=29^2

Simplify the squares:

400+b^2=841

Subtract 400 from both sides:

b^2=441

Take the square root of both sides:

b=21

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).
