Mount everest is 8847 m high. how many centimeters high is the mountain
nata0808 [166]
Before we answer the question we must first:
1. Assess what we have so far.
2. Know what we need to find.
3. Solve.
4. Conclude.

Step 1: What we have so far.
*Mt. Everest's height in meters (m) =  <span>8847m

Step 2: What we need to find.
*</span>Mt. Everest's height in centimeters (cm) = ?

Step 3: Solve.
*Centi means 100.
*1m = 100cm

Conversion process:
8847m x 100cm/1m <--- we need to multiply Mt. Everest's height to 100cm/1m first because our first agenda is to remove (m) from the value.
8847 x 100cm <--- this will be our working solution.
884,700cm <--- Answer

Step 4: Conclusion.
After successfully doing the steps above, we can now conclude that the height of Mt. Everest in centimeters is: 884,700cm

If f(x)=6x-15 and f(a)=30, what is the value of a?<br> Please help
mariarad [96]

Answer:

a=7.5

Step-by-step explanation:

Given the function f(x)=6x-15 and the output 30 when x=a, we can write the equation:

6a-15=30

6a=45

a=7.5

We can insert the value of a into the function to verify the output equals 30:

f(a) = 6a-15

= 6(7.5)-15

=30

∴ We have verified that a=7.5

Hope this helps :)

Simplify 8 over negative 4 divided by negative 3 over 9. 6 −6 12 −12
skelet666 [1.2K]

Answer:

6

Step-by-step explanation:

Given

\frac{8}{-4} /  \frac{-3}{9}

Required

Solve

\frac{8}{-4} /  \frac{-3}{9}

We start by converting the division sign to multiplication

\frac{8}{-4} /  \frac{-3}{9} =\frac{8}{-4} *  \frac{-9}{3}

Then, we divide -9 by 3

\frac{8}{-4} /  \frac{-3}{9}=\frac{8}{-4} *  -3

Then, we divide 8 by -4

\frac{8}{-4} /  \frac{-3}{9}=-2 *  -3

Multiply -2 and -3 to give final result

\frac{8}{-4} /  \frac{-3}{9} = 6

Hence, \frac{8}{-4} /  \frac{-3}{9} is equivalent to 6
