I really need help with this ASAP 71 POINTS

The time is 2:46 PM. What is the measure of the angle that the minute hand swept through since 2:00 PM?

Sonbull [250]

The minute hand has swept through 46 minutes on the clock. You have to set up a ratio to solve this:

$\frac{46\ minutes}{60\ minutes} = \frac{x\ degrees}{360\ degrees}$

You can compare the 60 minutes on a clock to 360 degrees because 60 minutes on a clock is one whole rotation. So then, you cross multiply and simplify:

$\frac{46\ minutes}{60\ minutes} = \frac{x\ degrees}{360\ degrees}\\\\46*360=x*60\\16560=60x\\276=x$

Therefore, the minute hand has swept through an angle with a measure of 276 degrees.

The ratio of angles angles A:B:C is 5:4:3 . find measure of angle A and B And C

mr Goodwill [35]

Answer:

A=75

B=60

C=45

Step-by-step explanation:

5+4+3=12

every triangle is equal to 180 so we divide

180/12=15

then we multiply each angle by 15

5*15

4*15

and 3*15

don't forget to check your work by adding the answers together to get 180

Your question is incomplete, here is the complete question:

The function below can be used to calculate the cost of making a long distance call, f(m), which is based on a $2.50 initial charge and a fee of $0.12 per minute, m, that the call lasts, f(m) = 2.5 + 0.12 m. If Natalie paid $6.82 for one call, how many minutes long was it

It was 36 minutes long

Step-by-step explanation:

∵ The function is f(m) = 2.5 + 0.12 m, where f(m) is the cost of a

distance call for m minutes

∵ Natalie paid $6.82 for one call

- Substitute f(m) by 6.82 in the equation above

∴ 6.82 = 2.5 + 0.12 m

- Subtract 2.5 from both sides

∴ 4.32 = 0.12 m

- Divide both sides by 0.12

∴ 36 = m

∴ The length of the call = 36 minutes

It was 36 minutes long

kim is renting a kayak on the hudson river . the cost of each boat is $10 and you have to pay $3.75 per hour that you rent each

DanielleElmas [232]

10+3.75h=21.25
Subtract 10 from both sides 3.75h=11.25
Divide each side by 3.75, h=3. Kim rented the kayak for three hours.
