Answer:

Answer 1: b. $104

Answer 2: b. $240

Step-by-step explanation:

Answer 1 explanation : Because he ended up with $71.00, the is no way he earned $64 or $13. He spent $7 on snacks, which means he would have had $78 then. But, he spent 1/4 of his money on the movie (not the snacks) so that means he would have more than $78 dollars to start with.

Answer 2 explanation: Because Jani spent half of her money on her bicycle, then and another half on a stereo set. That means she spent 1/4 of her money. Multiply 60 x 4, then you'll get 240.

Find the value of x .. assume that segments that appear to be tangent are tangent .

Rus_ich [418]

Answer:

sqrt(277) =x

x is approximately 16.64331698

Step-by-step explanation:

This is a right triangle since 14 is tangent to the circle and 9 is a radius

We can use the Pythagorean theorem to solve this problem

a^2 +b^2 =c^2

9^2+14^2 =x^2

81+196 = x^2

277 = x^2

Taking the square root of each side

sqrt(277) = sqrt(x^2)

sqrt(277) =x
