Answer:
20 hours
Step-by-step explanation:
To find the answer, you first should find out how long is 25% of the original battery life, 16 hours. To find this, you can divide 16 by 4, or multiply 16 by 0.25. Either works.
16/4=4.
So the new battery lasts 4 hours more than the old battery. Then, add this to the original length to find how long the new battery will last in total.
16+4=20
Answer:
all i know is that the perimeter is 24
Step-by-step explanation:
i also believe that the Coordinate on the top left is (-4,4) and the one below is (0,4)
Just work this problem out backwards. First write out an equation.
(x+4)•3=30
Now solve :
(x+4)•3=30
3x+12=30
-12 -12
3x=18
/3 /3
x=6
Your answer is 6!
Hoped I helped!
Answer:
110 and 70
Step-by-step explanation:
opposite sides of parallelograms are equal so you can set 2x+30 equal to 5x-90
when you do this:
2x+30=5x-90
-2x -2x
30=3x-90
+90 +90
120=3x
/3 /3
40=x
now you can plug 40 in for 5x-90
example:
5(40)-90
200-90
110
m<r=110
<r and <s are supplementary because they are consecutive angles
supplementary is when two angles add up to 180
since <r is 110, do 180-110 and get 70
m<s = 70
