What is the area of the shaded region to the nearest tenth of a foot?Part a) Explain what formulas you will use to find the area of the shaded area.

Par b) Explain how you find the area of the shaded region. What was your thought process?

Answers

Answer 1

Answer: a) The shaded region is that portion of the rectangle that is not in the circle. You need the formulas for the area of a rectangle and a circle.
Area of rectangle = length*width
Area of circle = (π/4)*diameter²

b) The figure shows the width of the rectangle is 14 ft, the same as the diameter of the circle. The length of the rectangle is shows as 21 ft. The shaded area is the difference ...
Shaded Area = Area of rectangle - Area of circle
Shaded Area = (21 ft)*(14 ft) - (π/4)*(14 ft)²
Evaluating this expression, we have
Shaded Area ≈ 294 ft² - 153.9 ft² = 140.1 ft²

Value of x in the solution to the system of equations.
6x+3y=13
3x-y=4

Answers

The two easiest ways to solve a system of equations (in my opinion) are to add the equations together while getting rid of a variable, or solving for a variable in one equation and plugging it into another. The latter is the method I will use.

3x - y = 4 (solve for y)
3x = 4 + y
3x - 4 = y
y = 3x - 4

Now we can plug y into the other equation:
6x + 3y = 13
6x + 3(3x - 4) = 13
6x + 9x - 12 = 13
15x = 25
x = 25/15
x = 5/3
The answer is x = 5/3

If you ever needed to find y as well, you can plug this into either equation to find y.
3x - y = 4
3(5/3) - y = 4
5 - y = 4
y = 1

243.875 to nearest tenth, hundredth, ten, and hundred.

Answers

Answer:

243.875 is 243.9 (rounded to nearest tenth)

243.875 is 243.88 (rounded to nearest hundredth)

243.875 is 240 (rounded to nearest tents)

243.875 is 200 (rounded to nearest hundred)

Step-by-step explanation:

To round a number, we look at the number next to the place value. If the number is more than or equal to 5 then add 1 with the place value.

243.875 to nearest tenth, hundredth, ten, and hundred.

2 is in hundreds place

4 is in tens place

3 is in ones place

8 is in tenth place

7 is in hundredth place

5 is in thousandth place

243.875 is 243.9 (rounded to nearest tenth)

243.875 is 243.88 (rounded to nearest hundredth)

243.875 is 240 (rounded to nearest tents)

243.875 is 200 (rounded to nearest hundred)

243.875

Nearest Tenth:- 243.9

Hundredth:- 243.88

Ten:- 240

Hundred:- 200

The number of apple s juan eats and the numbers of hours he sleep each night represents what type of correlation Positive

Median

Negative

No correlation

Answers

Answer:

No correlation

Step-by-step explanation:

With the information provided, we have to conclude there is no correlation, since there is no apparent link between the two information.

It would be a positive correlation for example if we knew that the more apples Juan eats, the more he sleeps (or vice-versa).

It could be a negative correlation if we found that the more apples he eats, the less hours of sleep he has (or vice-versa).

But in this instance, we don't have any data indicating there is any form of correlation between those two numbers.
