If Marita has one dime, she has 0.10 = 1/10 dollars. If she has "x" times that many dimes, she has 0.10x = x/10 dollars (in dimes).
The only answer choice containing this term is ...
( A ) x/10 + 0.75 + 10y
Use Pythagoras theorem. (a^2 + b^2 = c^2)
300^2+300^2 = 180000
√180000 = 424.3
The answer is 424 foot.
Hope this helps.
One can solve this by first using order of operations, and then combining like terms.
First is parenthesis
9x + 2x(9) - 2(9x)
Now we do the multiplication
9x + 18x - 18x
Now we combine like terms
9x
The formula is (degree)x(pi÷180)
36 x pi ÷ 180
0.63 rad
<span>Alex is 1.6 m tall
and
Noah is 1.5 times as tall as Alex
= 1.6 m x 1.5 = 2.4m
1 m = 100 cm
2.4 m = 2.4 x 100 = 240 cm
answer
Noah is 240 cm</span>
