Answer:
Hello! answer: 5
Step-by-step explanation:
What you do to find the answer for these is do a^2+b^2=c^2 Basically meaning 4 × 4 + 3 × 3 will equal a number that you then find the suare root of square root just meaning a number multiplied by itself to equals that number so...
4 × 4 = 16
3 × 3 = 9
16 + 9 = 25
√25 = 5
5 × 5 = 25 therefore c = 5 hope that helps!
If rounded to the nearest 10 is 530, then this number must be between 525 and 534. The only one which digits sum up to 11 is 533.
That "ad^3" bothers me; I'm not sure what you mean here.
I'm going to assume that you have (1/4*a*d^3)^2.
If that's the case, then you have (1/4)^2 * a^2 * d^6 = (1/16)*a^2*d^6.
If this is not what you were hoping for, double check to ensure that you have copied down this problem exactly as it was presented.
First, find the converting ratio for kilometers to miles, which is
1km = 1.61 miles.
Then, divide 410 on the side for miles on the ratio.
410km=254.67miles
Therefore, 410 km is equal to 254.67 miles.
Answer:
IT is not
Step-by-step explanation:
Let's replace. If it's a solution, it means that BOTH equations has to be true.
Now, the second equations seems good - 
indeed.
First alas isn't. RHS is 142, which is totally not the same as -10.
