Answer:
83.2 miles
Step-by-step explanation:
what i had to do was multiply 7.3 by 13 and that was 94.9 that was as close as i could get it to 100 so i then multipled 6.4 by 13 and got 83,2 miles
Answer:
Step-by-step explanation:
8:60 is the rate
Divided by 2
4:30
So, she could run 4 kilometers in 30 minuets.
Divide by 2 again.
2:15
She can run 2 kilometers in 15 minuets.
Answer:
p equals 7
Step-by-step explanation:
6p + 6 = 13 + 5p
you subtract 6 from 13 and 5p from 6p
p = 7
Answer:
Step-by-step explanation:
10% of 50 = 5
5% of 50 = 2.5
to get to 65 u do 5+5 = 10 so so far that is 20% but 20% only gets u to 60 so u add another 10% to reach 65
u have used 30% so the answer to yr question is 30%

a^2 + b^2 = c^2
Let c = hypotenuse = 2x
One of the legs = x. Let a or b = x.
I will let a = x. We can then say that b = 3.
3^2 + x^2 = (2x)^2
9 + x^2 = 4x^2
9 = 4x^2 - x^2
9 = 2x^2
9/2 = x^2
sqrt{9/2} = sqrt{x^2}
3/sqrt{2} = x
Rational denominator.
[3•sqrt{2}]/2 = x = a
Side 3 is given to be 3 feet. So, b = 3.
Hypotenuse = 2x
Hypotenuse = 2([3•sqrt{2}]/2)
Hypotenuse = 3•sqrt{2}
Understand?
The three sides are 3, [3•sqrt{2}]/2 and
3•sqrt{2}.
