Answer: w= 1/5
Step-by-step explanation:
11/15=8/15 -w
-W= 8/15 -11/15
-w= 8-11/15 =-3/15
-w=-3/15
w=3/15= 1/5
Answer:
18.6 months
Step-by-step explanation:
Given that :
Best fit line from scatterplot :
y=-12.05x +224.26
x = Number of month
y = charge on battery
Number of months a typical battery uses before being dead completely :
When battery is dead completely ; charge =0, y = 0
y = -12.05x + 224.26
0 = - 12.05x + 224.26
12.05x = 224.26
x = 224.26 / 12.05
x = 18.610788
Hence, 18.6 months before battery is completely dead.
Answer:
<u>93°</u>
Step-by-step explanation:
According to angle sum property, all the internal angles of a triangle add up to 180 degrees.
=> 37 + 50 + ? = 180
=> ? = 180 - 87
=> ? = <u>93°</u>
30000= 100%
x=5%
30000/x=100/5
<span>(30000/x)*x=(100/5)*x
</span>30000=20*x
30000/20=x
x=1500
5%of 30000 is 1500
