120 degrees because the hour hand will be in 4. Which is 20 min and its 1/3 of an hour

A circle is 360 degrees, and there are 12 sections on a clock. Divide 360 by 12, which will get you 30. The hand moves 4 hours, so you would multiply 30 times 4 and get 120 degrees. I hope I helped!

alexdok [17]

Answer:

10.5 hours

Step-by-step explanation:

Given:

This week Andres will practice with his band for

$1\frac{1}{2} \ means\ \frac{3}{2} \ hours$ on Monday

$1\frac{3}{4} \ means\ \frac{7}{4} \ hours$ on Tuesday

2 hours Wednesday.

Next week Andres will practice with his band for the same number of hours on Monday, Tuesday, Wednesday.

Question asked:

What was the total number of hours Andres will practice with his band over these 6 days?

Solution:

As she practice for two weeks, three days of each week:

On two Monday, she will practice = $\frac{3}{2} + \frac{3}{2} =\frac{3+3}{2} =\frac{6}{2} =3\ hours$

On two Tuesday, she will practice = $\frac{7}{4} +\frac{7}{4}=\frac{7+7}{4} =\frac{14}{4} =\frac{7}{2} \ hours$

On two Wednesday, she will practice = $2+2=4 \ hours$

Total hours, she will practice over 6 days $=3+\frac{7}{2} +4$

$=7+\frac{7}{2} \\ \\ =\frac{2\times7+7}{2} \\ \\ =\frac{21}{2} \\ \\ =10.5\ hours$

Thus, Andres will practice 10.5 hours with his band over these 6 days.

Two straight lengths of wire are placed on the ground, forming vertical angles. If the measure of one of the angles formed is 72

lord [1]

One of the other angles is 72. Vertically opposite angles are equal.

Two angles that are side by side on this arrangement are supplementary.

That means they are to 180

x + 72 = 180

x = 180 - 72

x = 108

Answer

the for angles are

72 + 72 + 108 + 108
