Answer:

Because the angle opposite the angle's head equals 70 when combined with the angle of 110, the two angles become complementary and form something like the letter U, so the two lines are parallel.

A map of a bike race has a scale of 2 inches=50 miles. The distance to the 1st aid station from the starting line is about 1.25"
svp [43]
2 inches = 50 miles
1 inch = 25miles
0.5 inches = 12.5 miles
0.25 inches = 6.25
you need 1.25 so you do 25+ 6.25 and get 31.25. To the nearest mile this would be 31 miles.

Pls can someone help me with math pls I’m this is my last points..
LiRa [457]

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>

1. 3.81 = 3.8 because 8 is in the tenths place and you rounded it. 1 is less than 5 so the number stays the same.
2. 72.27 = 72.3 because 2 was in the tenths place and you rounded it by 7. 7 is more than 5 so the number changes to 3.
The number beside the number you want to round on the left must be equal or more than 5.
3. 167.79 = 167.8 4. 67.04 = 67 5. 1.356 = 1.36 6. 0.048 = 0.05
7. 8.333 = 8.33 8. 1.9973 = 2 9. 7.4 = 7 10. 171.68 = 172
11. 0.0018 = 0 12. 600.55 = 601
