Answer:
8.) -120
9.) -5
10.) -1
Step-by-step explanation:
8.) ab - c
5(-12) - 60
-60 - 60 = -120
9.) -10 - (-7) + 2 (3 - 4)
-3 + 2(-1)
-3 + (-2) = -5
10.) Add all the numbers up then divide by how many numbers there are.
Answer:
The measurement was off by 0.7%
Step-by-step explanation:
To find the relative error in the measurement, start by finding the difference.
36 - 35.75 = 0.25
Now divide that by the actual measurement of the door.
0.25/35.75 = 0.7%
Step-by-step explanation:
Two lines that are parallel have the same slope. If we make 
in to slope-intercept form it'll be like this:
Now we know 
as its slope-intercept form we can see the slope is 
.
has the same slope as so they are both parallel.
<h3>Answer:</h3>
Slant height is about 8.544.
Lateral area is about 96.93.
Surface area is about 144.93.
Volume is 96^3.
For this type of problem,
It is stated that the weight of steel is 32.6 lbs per foot
Meaning, every foot of steel beam weighs 32.6.
So 2 feet of steel beam would weigh 32.6 x 2 = 65.2 lbs
and 3 feet will be 32.6 x 3 = 97.8 lbs
Since we have a limit of 5000 lbs which is the capacity of the truck.
We can have an equation :
Where x is the number of foot
Solve the value of x by dividing both sides by 32.6 :
So the answer is 153.37 feet of steel beam
