Round ur quotient and the divsor like 100 divide by 9... would be about 11 and 9 is about 10 and 11 is about 10 so 10 times 10 is one hundred ao the quotient is reasonable

It is something that is helpful because then you can find out if you are in the right ball park when you find the actual answer. If your actual answer isn't even close to the estimated one, you will know that it probably isn't the right answer.

Two sides of an acute triangle measure 5 inches and 8 inches. The length of the longest side is unknown.

nordsb [41]

The greatest whole possible whole number length of the unknown side is 9 inches

Solution:

Two sides of an acute triangle measure 5 inches and 8 inches

The length of the longest side is unknown

We have to find the length of unknown side

The longest side of any triangle is a hypotenuse

For a acute triangle we know:

If c is the longest side of a acute triangle, a and b are other two sides of a acute triangle then the condition that relates these three sides are given as:

$c^2$

Here in this sum,

a = 5 inches

b = 8 inches

c = ?

Substituting we get,

$c^2< 5^2+8^2\\\\c^2 < 25 + 64\\\\c^2 < 89\\\\c < 9.4$

On rounding to nearest whole number,

c < 9

Hence, to the greatest whole possible whole number length of the unknown side is 9 inches

Write the number 1/10,000,000 as a power of 10 using a negative exponents

allochka39001 [22]

First, convert into a decimal:

1/10,000,000 = 0.00000001

Next, convert to "the number with a power of 10 using a negative exponent. Move the decimal point to the first number that is not 0 (sorry, there is a term for it, but i can't remember it right now, but it is not important to solving the answer)

0.000001 = 1 * 10^-7

1 * 10^-7 is your answer
