Since she makes $13 per hour, she would have to work 5 hours to make $65.
Answer:
120x^3
Step-by-step explanation:
exponent rule --> a^b x a^c = a^b+^c
10^-6 x 10^7 = 10^6 + ^7
add / subtract numbers -- > -6 + 7 = 1
=2XX x 6X x 10
aponent rule --> a^b x a^c = a^b+^c
xxx = x^1 + ^1 + ^1
= 2 x 6x^1 + ^1 + ^1 x 10
= 2 x 6x^3 x 10
= 120x^3
Answer: First I suggest that you write out the all the proportions which govern the 3 right triangles involved.
Once you do that you will find this one:
PQ/PS =PR/PQ
PR=PS+SR
Substitution will give you this quadratic:PQ2=PS2+PS*SR
144=PS2+7PS which has only one solution which make sense, namely 9
Then QS=sqrt(144-81)
Step-by-step explanation:
The answer is 3/28. Make then have the common denominator which is 28. After that times the TOP.
