Janesa has 24 coins in her pocket worth exactly $1.00. She tells her younger brother Jackson that he can have the coins if he correctly guesses how many of each coin she has. She gives him the hint that there are only nickels and pennies.

19 Nickels and 5 Pennies.

Step-by-step explanation:

19 * 5 = 95

5 * 1 = 5

95 + 5 = 100 or 1.00.

Hope this helps!

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
