Answer:
He jogs 4 9/10 kilometers in 6 1/8 minutes
Step-by-step explanation:
If you multiple 4/5 time 6 1/8 you'll get 4.9, which in fraction form is 4 9/10.
The answer to this question is: 15
Answer:
15;9;-8
Step-by-step explanation:
1. 5/3x-3=2/3x+12
x=15 once you combine like terms
2. 5x+35-3x+12=7x+2
2x+47=7x+2
5x=45
x=9
3. 12x+20-3=9x-7
12x+17=9x-7
3x=-24
x=-8
Answer:
Step-by-step explanation:
1. Height of the equilateral triangle = a√3/2
8√3/2=4√3=6.9
2. 60 (equilateral triangle means all three sides and angles are equal)
Answer:
no
Step-by-step explanation:
so in order for it to be a right triangle this would have to be true:
a^2 + b^2 = c^2
since c represents the hypoteneuse, it will be the longest side. so:
60^2 + 63^2 = 88^2
3600 + 3969 = 7744
7569 = 7744
since that statement is not true, the answer is no.
it is not a right triangle
the square root of 7569 is 87, so the triple would have to be : {60,63,87}
