Answer:

781200 cm or 7.81200x10^5 cm

Step-by-step explanation:

Here, you need to solve it with the area equation.

For a rectangle, it's base x height.

In this case, your base will be it's  length 9.3x10^{2} cm = 930cm\\, and its height will be width 8.4x10^{2} cm = 840cm.

An then you can solve it

(9.3x10^{2})*(8.4x10^{2})=781200 cm = 7.81200x10^{5}

Easton wants to put a variety of donuts in a display case. The case is large enough to hold 100 donuts. Complete the table below
shutvik [7]

The amounts for each donut are given as follows:

  • Strawberry: 15.
  • Chocolate: 45.
  • Sprinkle: 40.

<h3>How to obtain the amounts?</h3>

The amounts for each donut are found applying the proportion, multiplying the decimal equivalent of each percentage by the total number of donuts.

From the problem, the total number of donuts is given as follows:

100 donuts.

The percentages of each type of donuts are given as follows:

  • Strawberry: 15%.
  • Chocolate: 45%.
  • Sprinkle: 40%.

The decimal equivalent of each percentage is given as follows:

  • Strawberry: 0.15.
  • Chocolate: 0.45.
  • Sprinkle: 0.4.

Hence the amounts are given as follows:

  • Strawberry: 15, as 0.15 x 100 = 15.
  • Chocolate: 45, as 0.45 x 100 = 45.
  • Sprinkle: 40, as 0.4 x 100 = 40.

sergejj [24]

Answer:

Ben's rate is \dfrac{1}{6} greater than Kate's rate.

Step-by-step explanation:

1. If it takes Ben 2 days to write reports, then his rate is \dfrac{1}{2} of reports per day.

2. If it takes Kate 3 days to write reports, then her rate is \dfrac{1}{3} of reports per day.

3. Ben's rate is

\dfrac{1}{2}-\dfrac{1}{3}=\dfrac{3-2}{6}=\dfrac{1}{6}

greater than Kate's rate.

Talja [164]
The answer would be A. 39,300.

I got this by multiplying 34,500 by 2% and getting 690. Since 2018 is 7 years away from 2025, I multiplied 690 by 7 getting 4,830. I added the 4,830 to the original population of 34,500 and got my answer, 39,300. Hope I helped!
