The cosine of B = 4/5 so the adjacent side divided by the hypotenuse = .8
So 10/.8 = 12.5 the length of the hypotenuse

A light bulb consumes 1440 watt-hours per day. How many watt-hours does it consume in 4 days and 18 hours.
dimaraw [331]

Answer:

6840

Step-by-step explanation:

Well we know there's 24 hours in a day so dividing that by 1440 we get 60. Now we know that it consumes 60 watts ever hour. so now we just have to figure out how many hours there are and times that by 60. So there are 96 hours in 4 days plus 28=114. So times that by 60 ( watts) 114×60=6840

So that's your awnser.

Hope this helps!! If so please mark brainliest and rate/heart to help my account if it did!!

Can someone answer this question please answer it correctly if it’s correct I will mark you brainliest

Answer: 105

Step-by-step explanation: 25 frames is 1 second. The video already played 3 and 2/5 seconds before the player started to count 0, so you can write 3 and 2/5 seconds as an improper fraction. =(5*3)+2 / 5 = 17/5 seconds. Multiply by 25 frame. 17/5 *25 =85 frames. So according to the video counter,after 17/5 seconds,it should count 85 frames.However,at 0 seconds,it indicated a count of 190 frames. then to get the number of frames that were already in count you would subtract 85 frames from the 190 frames.

190-85=105 frames

(Not 100% sure so apologies if I'm wrong)

What is an algebra expression for 12m + 12n
irinina [24]
An expression when dealing with math does not have an equal sign. So, technically 12m + 12n is already an expression.

It can be simplified to
12(m + n) if that helps any. Good luck!
