What is the degree measure of the smaller angle formed by the hour and minute hands of a 12 hour clock?
Georgia [21]

<u> 359.905 degrees</u> is the answer.

Step-by-step explanation:

when it comes to the hour hand it moves about 360 degrees in a 12 hour clock for instance let us take the time 6:15 then the calculation is

=(6+15/60) * 360÷12

= 187.5 degrees.

when it comes to the minute hand the minute hand travels 360 degrees for every 60 minutes in a 12 hour clock so if it is 5 mins past in the time 6:05 then it can be given as

15/60 * 360 = 90 degrees

Difference between the two hand can be  calculated by

(Angle turned by the hour hand) - (Angle turned by the minute hand)

<u>For a smaller angle let us take 12:01 </u>

= (12+1/60) * 360÷12

=360.5

for the minute hand

=1/60 = 0.595

(Angle turned by the hour hand) - (Angle turned by the minute hand)

= 360.5 - 0.595

=<u> 359.905 degrees</u>

YALL HELP<br> plz give me a fraction problem that contains division and multiplication !!
Luba_88 [7]

Answer:

This one is a bit easy, so if you need a harder one, just let me know.

((32/48) x (4/6)) / (2/5)

Step-by-step explanation:

1) You can simplify both (32/48) and (4/6) to (2/3).

2) Multiply (2/3) by itself, giving (4/9).

3) Dividing by a fraction is equivalent to multiplying by its reciprocal, or opposite. In this example, the reciprocal of (2/5) is (5/2). Thus, (4/9) x (5/2) = (20/18).

4) Simplify your answer, to (10/9) or 1 and 1/9 (as a mixed fraction).

A hiker is walking down a mountain. She walked​ 5,978 feet in 17 minutes. In that​ time, she descended​ 1,024 feet from the top
olya-2409 [2.1K]

Answer:

63.5 feet/minute

Step-by-step explanation:

She first descended 1,024 feet in 17 minutes

Then she descended 500 feet in 7 minutes

The total feet descended is 1,024 + 500 = 1,524 feet

The total time to descend is 17 + 7 = 24 minutes

The average rate of change in altitude is  

Altitude descended / time

1,524 feet / 24 minutes

63.5 feet /minute

How do you answer this equation?<br> 5a - 12 = 48
IgorC [24]
Add 12 to both sides resulting in 5a = 60 and then divide both sides by 5 which results in a = 12 so your answer will be a = 12
