From midnight to 6:00 am, the temperature rose 1.05°C each hour. If the temperature at 6:00 am was -5.7°C, what was the temperature at midnight?

Answers

Answer:

13.2 C

Step-by-step explanation:

6am the temp is at -5.7

from 6am to 12pm is 18 hours apart

so if the temp rises at 1.05 every hour you multiply 1.05*18= 18.9

18.9-5.7=13.2

The hour hand of a clock moves from 3 to 8 o'clock through how many degrees does it move

Answers

The number of degrees does it move is 150 degrees.

The following things should be considered:

  • Since there are 12 parts.
  • Each one should we 30 degrees i.e. = 360/ 30
  • Now 8 - 3 = 5
  • So, the angle should be = 5* 30 = 150 degrees.  

Therefore we can conclude that The number of degrees does it move is 150 degrees.

There is a picture.
There 12 parts. Each one is 360/12=30°.
8-3=5 we have.
So, the angle will be 5*30=150°.

a + b  +c = 10

a + b - c = 3

 find the value of

a + b + 3c


Answers

ok if you look at the first to equations carefully you will see that 2 things have changed between the 2. the "+c" is now "-c" and the "10" is now "3"

if we think about it you will see that c=7. well how do we know. when c or 7 was taken away from the problem it left you with 3 

so that means a+b=3

we dont need to know what the exat value of a or b is.

so a+b +3c
      (3) + 3(7)
       3   +  21
         24

a+b+3c=24

∠E and ∠F are vertical angles with m∠E=8x+8 and m∠F=2x+38.

What is the value of x?

Answers

As they are vertical angles, their magnitude will be equal.
8x+8 = 2x+38
8x-2x = 38-8
6x = 30
x = 5

So, Your Final Answer would be 5

Hope this helps!
