What is the approximate area of shadad region? use 3.14 π

A. 16.86
B. 19
C.18.43
D.23.14

Answers

Answer: A) 16.86 square inches

Step-by-Step Explanation:

Area of Shaded Area will be the Area of the Rectangle (Total Area) minus the Area of the Circle.

Finding Area of Circle :-

Radius (r) = 1 in
Area = πr^2

Therefore,
= πr^2
= π * r * r
= 3.14 * 1 * 1
=> 3.14

Area = 3.14 in^2

Finding Area of Rectangle (Total Area) :-

Length (l) = 5 in
Breadth (b) = 4 in
Area = l * b

Therefore,
= l * b
= 5 * 4
=> 20

Area = 20 in^2

Finding Area of Shaded Region :-

Area of Rectangle - Area of Circle

Therefore,
= 20 - 3.14
= 16.86

Area = 16.86 in^2
16.86 square inches,

Explanation

5in • 4in - (1 squared • 3.14)

Step-by-step explanation:

1. How many were surveyed? 82+8+18+62=100

2. How many said Jalepeno was their favorite? 8/100 0r 2/25 or 8%

3. How many said BBQ was their favorite?62/100 or 31/50 or 62%

4. How would it effect your final answer if the percentages did not add up to 100%? This means that your percentages are wrong. In a circle graph the percentages always equal 100%!

5. Is it possible to determine a missing percentage in a circle graph? Yes, we can always assume the total percentage is 100 so you add your given percentages together and then subtract that total from 100 to find the missing percentage.

How would you use the coordinate plane to determine the area of Figure 3 on the graph below?

Answers

To identify the area of the figure, the amount it occupies on the x-axis and on the y-axis must be identified, and finally it must be multiplied.

How to identify an Area with the Coordinate Plane?

To identify the area of figure 3, its extension must first be identified on one of the axes, for example, the x-axis, where its extension is:

Extension of the figure on the x axis = 2 (since it goes from 7 to 9).

Then its extension on the y-axis must be identified, which is:

Extension of the figure on the axis y = 5 (since it goes from 5 to 10)

Finally, the two visualized extensions must be multiplied to obtain the area of the figure:

Figure area = Extension x * Extension yArea of the figure = 2 * 5Figure area = 10

Units are not used as they are not specified in the drawing or information, but could be square inches or square feet.

1/2 + 1/2 = 1
1 + 1/2 = 1.5
1.5 + 1/2 = 2

given:

[tex]2 \div \frac{1}{2} [/tex]

solution:

[tex] \frac{2}{1} \div \frac{1}{2} [/tex]

[tex] = \frac{2 \times 2}{1 \times 1} [/tex]

PLSS HELPPP!!!!!! HURRYYY!!! THXXX!!!Kylie compared the price per pound of two types of apples at her grocery store. She used the equation y=0.85x to represent y, the total cost in dollars of x pounds of apple A. She entered into the table below the cost of some weights of apple B.




What is the difference in the price per pound between apple A and apple B?


A

$0.40


B

$0.85


C

$1.25


D

$2.10

Answers

Answer:

Choice A is the correct answer.

Step-by-step explanation:

We can compare the prices by taking one of the weight values from the table for apple B and plug it into the equation for apple A.

For example, let's take 4 from the table. The equation would look like this:

y = 0.85(4) = $3.40.

This is the price of 4 pounds of apple A. However, the price for 4 pounds of apple B is $5.00.

5.00 - 3.40 = $1.60. This is the difference in price between 4 pounds of apple A and 4 pounds of apple B. If we want to find the difference per 1 pound, just divide 1.60 by 4.

1.60 / 4 = $0.40.

Therefore, the answer is Choice A.

How I divide by negative?? I forgot completely

Answer:

I hope this helps. If I misunderstood the question let me know

Step-by-step explanation:

1. When dividing a negative by a negative, your answer would be positive.

2. When dividing a negative by a positive, your answer will be negative.

3. When dividing a positive by a negative,your answer will be negative.

Answer:

Divide like you normally would, the result will be the same as positive-number-quotients, but the quotient will be negative.

Example:

10 ÷ -5

since 5 is the dividend, 5 goes into 10 two times but note that it's negative two because of the negative division logic.

500 people are asked to name their favorite color. The results of this survey are shown in the pie chart below:


Each sector of the pie chart makes an angle at the center. For example, the yellow sector makes an 18-degree angle, since 18 degrees is 5% of 360 degrees.

Which sector makes an angle closest to 40 degrees (Your answer should be a color word.)

Answers

The answer would be the Blue sector.

Because 15% of 360° is 37.2

37.2 is only 2.8 away from 40 making it the closest!

Answer:

Purple

Step-by-step explanation:

40° is one-ninth of 360°. As a percent, this is equal to

1/9 ∙ 100% = 11.111111111111111111111111111111111111111111111111...%

Of all the sectors in the pie chart, the one closest to 11.111111111111111111111111111111111111111111111111...% is purple, at 12%.

Write an equation that represents the situation.

Answers

the answer is 3 times q + 7 = 40 because there are 4 sides and 3 of the sides are equal as one of them is 7 so you add 7 to the total amount after multiplying q three times
Q = 11. 3q + 7 = 40. Since the q sides are the same length and the total perimeter is 40, you use the equation and get 11.
