Answer:
h = -t+20
After 8 hours the candle will be 12 inches
Step-by-step explanation:
We have 2 points (time, inches)
(3,17) and (5,15)
We can find the slope
m = (y2-y1)/(x2-x1)
= (15-17)/(5-3)
= -2/2
= -1
We can use point slope form
y-y1 = m(x-x1)
Replace y with h and x with t
h-17 = -1 (t-3)
Distribute
h-17 = -t+3
Add 17 to each side
h-17+17 = -t+3+17
h = -t+20
After 8 hours
h = -t+20
h = -8+20
h= 12
Answer:
8.14 feet
Step-by-step explanation:
8.14 feet will be more precise because it measures to the hundredths place, while 13.2 feet only measures to the tenths place.
Measuring to smaller place values increases precision and accuracy because the measurements are more likely to be more exact and correct.
So, 8.14 feet is more precise
Answer:
7:4
Step-by-step explanation:
42:24
divide both sides by 6
7:4
Answer:
B. 24
Step-by-step explanation:
To find this, use Pythagorean Theorem
a^2+b^2=c^2
a is 10, and c is 26. We know 26 is the hypotenuse because it is opposite the right angle
10^2=b^2=26^2
100+b^2=676
Subtract 100 on both sides
b^2=576
Take the square root of both sides
b=24
Hope this helps! :)
