Answer:

Please read all of this! Underlined things are the answers. The area of the entire circle is 19.625

Step-by-step explanation:

(This is a circle so the middle line is the diameter. According to the attachment, the diameter is 5 cm. To find the area, we have to multiply π and the radius squared. The radius is half of the diameter.

5 ÷ 2 = 2.5

2.5² = 6.25

π = 3.14

3.14 x 6.25 = 19.625)

Ignore the top I just realized what I'm supposed to do but I left it there just in case you need help!

<u>The right and left shaded regions areas are 6.28 each.</u>

4 ÷ 2 = 2

2² = 4

3.14 x 4 = 12.56

Since this is a semi circle, we cut it in half.

12.56 ÷ 2 = 6.28

To find the top and bottom shaded region's areas, repeat the same steps.

3 ÷ 2 = 1.5

1.5² = 2.25

3.14 x 2.25 = 7.065

7.065 ÷ 2 = 3.5325

<u>The areas of the the top and bottom shaded regions are 3.5325 each.</u>

What is the total length of the tadpoles that are 1/8-inch and 1/4-inch long?
nasty-shy [4]

The dot plot shows the frequency or length of the tadpoles

The total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches

<h3>How to determine the total length?</h3>

From the dot plot, we have the following parameters:

  • 3 tadpoles have a length of 1/8
  • 2 tadpoles have a length of 1/4

So, the total length is:

Total = 3 * 1/8 + 2 * 1/4

Evaluate the product

Total = 3/8 + 1/2

Rewrite as;

Total = 3/8 + 4/8

Evaluate the sum

Total = 7/8

Hence, the total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches

Express the equation x = 10 and y = -3 as a linear equation in two variables
34kurt

Answer:

For x = 10:

x + 0y - 10 = 0

For y = - 3:

0x + y + 3 = 0

Step-by-step Explanation:

Before we start let's recall the formula for the linear equations.

ax + bx = c

So first let's solve for x=10:

x = 10

Move 10 to the other side.

x - 10 = 0

As there is no y given we will simply write 0y.

x + 0y  - 10= 0

Now let's solve for y=-3:

y =  - 3

Move -3 to the other side.

y + 3 = 0

As there is no x given we will simply write 0x.

0x + y + 3 = 0
