Multiply by .8025
when doing percents, move decimal points two places to the left to turn it into a decimal
for example, 10% is .1
8 pm to midnight (12 pm) = 4 hrs
so the temp dropped -16.8 in 4 hrs (because the temp started at 0)
-16.8/4 = -4.2....so it dropped 4.2 every hr.
temp at 9 pm (1 hr after 8) would be (0 - 4.2) = -4.2
The answer would be $51.36
48.00 x 7% = 3.36
48.00 + 3.36 = $51.36
Answer:
x would be equal to 1.1
Step-by-step explanation:
<u>Step 1: Determine the value of x</u>
I assume that the equation looks like this: 16/x = 45/3
Therefore, using the cross multiply method we can do (16*3) = (x*45)
This will give us 48 = 45x
Then we divide both sides by 45 so we can isolate x by itself
45x/45 = 48/45
x = 1.0667
Then we round to the nearest tenth
x = 1.0667
x = 1.1
Answer: x would be equal to 1.1
Because the points are on the same line, the slope that is found using these points is the same
m1=m2
(y-y1)/(x-x1)=(y-y2)(x-x2)
(y-11)/(x+8)=(y-7/2)/(x-4)
(y-11)(x-4)=(y-7/2)(x+8)
yx-4y-11x+44 = yx +8y-(7/2) x-28
-4y-11x+44=8y-(7/2) x-28
8y+4y=-11x+(7/2)x+72
12y=-(22/2)x+(7/2)x+72
12y=-(15/2)x+72
y=-(15/(2*12))x+72/12
y=(-5/8)x+6 correct answer
