We need more details to answer. You did forget to mark ST as 16 but I see no problem with the NQ. NQ should be self-similar to SU.

Thats about 9:12. She should have enough information for them to be self-similar because you can find angle S by adding angle T and U together and subtracting 180 by the sum of those numbers.

I am not sure what the question is asking though specifically so can you provide more info

Joni’s hair is 13 inches long and grows at an average rate of ⅔ in per month. Her friend Kate’s hair is 16 inches long and grows

Gelneren [198K]

<h3>18 months will pass before the two friends have the same hair length</h3>

Solution:

Let "x" be the number of months

Joni’s hair is 13 inches long and grows at an average rate of ⅔ in per month

$Equation : 13 + \frac{2}{3}x ------- eqn\ 1$

Her friend Kate’s hair is 16 inches long and grows at an average rate of ½ in per month

$Equation: 16 + \frac{1}{2}x ----- eqn\ 2$

For two friends to have the same hair length, eqn 1 must be equal to eqn 2

$13 + \frac{2x}{3} = 16 + \frac{x}{2}\\\\\frac{2x}{3} - \frac{x}{2} = 16 - 13\\\\\frac{4x}{6} - \frac{3x}{6} = 3\\\\x = 18$

Thus 18 months will pass before the two friends have the same hair length

In the number 550, is the value of the 5 in the tens place ten times greater than the value of the 5 in the hundreds place? Expl

7nadin3 [17]

Nope, the value of the 5 is 5 tens which is 50 in the tens place.
The value of the 5 in the hundreds place is 5 hundreds which is 500.
Therefore the 5 in the tens place is actually ten times less than the 5 in the hundreds place.
