She needs to wash 7 cars.
Answer:
SD = 2x
UD = x![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Step-by-step explanation:
The hypotenuse of a 30-60-90 triangle is 2 times the length of the shorter leg.
SU is the shorter leg = x
So, SD = 2x
The longer leg of a 30-60-90 triangle is
times the shorter leg.
So, UD = x![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
50 is a composite number. 50 = 1 x 50; 2 x 25; or 5 x 10. Factors of 50: 1, 2, 5, 10, 25, 50.
Prime factorization: 50 = 2 x 5 x 5.
You move the +4a to the left side of the equal sign and that becomes a negative
9a-2-4a=c
You move -2 to the right side of the equal sign and that becomes a positive
9a-4a=c+2
Combine like terms
5a=c+2
Divide by 5 from each side
a=(c+2)/5
Answer:
we know that
Hillary
swims every 6 days---> Multiples of 6---> 6-12-18-24-30-36-42-48-54
runs every 4 days-----> Multiples of 4----> 4-8-12-16-20-24-28-32-36-40-44-48
cycles every 16 days---> Multiples of 16---> 16-32-48-64
therefore
In 48 days she will do all three on the same day.
the answer is
48 days
