The difference between nine times a number an 7 is -70. find that number

Answers

Let's assume

that number is x

now, we are given

The difference between nine times a number an 7 is -70

nine times of that number is 9x

so, we can set up equation

$9x-7=-70$

now, we can solve for x

$9x-7+7=-70+7$

$9x=-63$

$x=-7$

so, number is -7.........Answer

Which set of side lengths form a right triangle

Answers

I would think C. The normal theorem to use on this is a^2 + b^2 = c^2. This only works for choice c. 6^2=36. 8^2=64 10^2=100. 36+64=100. That makes C correct.

There are a few possibilities, you could have 60 degrees 30 degrees and 90 degrees, for one triangle those added up equal 180 which is needed to make a right triangle. Another possibility would be 45 degrees 45 degrees 90 degrees, those added up equals to 180 degrees. :D

What is (3.5 x 10 to the fourth) to the secondwhen written in scientific notation with four significant digits?

Answers

so that is 3.5 times 10000 or 35000
then it is squared so 1,225,000,000 but to four significant digits it would be 1225 times 10^6 or on a online test 1225e+06

Exponents raised by exponents are resolved by multiplying the two exponents together . . . so distribute the exponent to the paranthesis

note:
3.5 = 3.5^1

(3.5 x 10^4)^2

(3.5^1*2 x 10^(4*2))

(3.5^2 x 10^8)

12.25 x 10^8

1.225 x 10^9
