Peggy has saves 9,215. If she is paid $45 an hour, how many hours did she work?

Mathematics

First we set up our equation.  We know she has $9,215, and she gets paid $45 an hour.  So our variable would be the hours she has to work.

45n=9,215

Since we don't have any like terms to combine, we just divide both sides by 45, to isolate the variable.

n=204.8  Hope this helped!

True or false: the height is always twice the length of the base edge for any triangular pyramid
AleksandrR [38]

Answer:

FALSE

Step-by-step explanation:

The length of the base edge of a triangular pyramid may vary.

Mohit pays rupees 9000 as an amount on the sum of rupees 7000 that he had borrowed for 2 years.
Sphinxa [80]

Answer:

The required rate of interest   =   14.285%

Step-by-step explanation:

Here, The principal amount = 7,000

The final paid amount = 9,000

Time = 2 years

Let us assume the rate of interest = R

Now, Simple Interest  =  Amount - Principal

                                      =  9,000 - 7,000  = 2,000

So, the SI on the given principal for 2 years  = 2,000

\textrm{SIMPLE INTEREST } = \frac{P \times  R \times T}{100}\\\implies 2000 = \frac{7,000 \times  R \times 2}{100}\\\implies R = \frac{2,000 \times 100}{7,000 \times 2}  = 14.285

or, R =  14.285%

Hence, the required rate of interest   =   14.285%

  • In the 3rd and 4the bar of histogram, the data is jumped from 14 to 20 instead of 15.
  • The frequency distribution in histogram for this data is inconsistent.
  • This inconsistency brought the between the two graphs.

Thus, the reason of one graph appears skewed, and one graph appears symmetric is the interval on the x-axis of the histogram is inconsistent.
