Answer:
7. <B = 129°8. <N = 85°Step-by-step explanation:
7. <A + <B = 180° [Since Co-interior angles]
=> 51° + <B = 180°
=> <B = 180° - 51°
=> <B = 129° (Ans)
8. <M + <N = 180° [Since Co-interior angles]
=> 95° + <N = 180°
=> <N = 180° - 95°
=> <N = 85° (Ans)

The time t required to drive a certain distance varies inversely with the speed r. If it takes 2 hours to drive the distance at 40 miles per hour, how long will it take to drive the same distance at 45 miles per hour?
A. 80 hours
B. 900 hours
C. about 1.78 hours
D. 2.25 hours
Answers
Answer:
C. about 1.78 hours
Step-by-step explanation:
Answer:
1.78 hours
Step-by-step explanation:
If t varies inversely with the speed, the formula for that is t= \frac{k}{r} . If t = 2 and r = 40, then we can solve for k, the constant of variation. Multiply both sides by 40 to get k = 80. Now we need to find the value for t when r = 45. Using the k value we just solved for, we will fill in the equation as t= \frac{80}{45} for a t value of about 1.78 hours
...............................................................................................................................................
Answer: about 1.78 hours
...............................................................................................................................................
t = k/r
2 = k/67
k = 134 (which happens to be the distance)
t = 134/r
t = 134/55
t = 2.436 hours
...............................................................................................................................................
The formula for this is t = k/r, read "t varies inversely as r". If the info they give us is 4 hours and 35 miles per hour, we find that k = 140. Now use that 140 in another equation to solve for t: t = 140/45, and t = 3.1 hours
...............................................................................................................................................
t = k/r\
4 hours and 35 miles per hour,
we find that k = 140.
Now use that 140 in another equation to solve for t:
t = 140/45, and
t = 3.1 hours

Drops = 27
First, we need to find the volume of the given tank using the following equation
[tex]Volume = Length*Width*Height\\Volume =14*9*10\\Volume =1260\\[/tex]
Now that we know the volume, we need to find out how many drops that we need to use. We can find that out using the following equation
[tex]Drops = 3\frac{Volume}{140} \\Drops = 3\frac{1260}{140} \\Drops = 3(9) \\Drops = 27[/tex]

A company charges a shipping fee that is 4.5% of the purchase price for all items it ships. What is the fee to ship an item that costs $70? Round to the nearest cent (hundredths place).
Answers
Answer:
3.15 cents
Step-by-step explanation:
So, lets go over all the information we know.
First off, we know that the cost of the item is 70 dollars.
Secondly, we know that the fee is 4.5% of 70 dollars.
Now, what is 4.5%?
Well, we know that 100% is qual to 1.
So lets divide 4.5 by 100, which is just moving the decimal point back by 2:
0.045
Now, the last thing to do is multiply 0.045 by 70.
0.045x70
=
3.15
So now we know the fee for a 70 dollar item is 3.15 dollars!
Hope this helps ;)

The high temperatures for the last seven days are: High Temperatures: 81, 78, 83, 89, 80, 87, 78
Find the MEAN of the temperatures. Round to the nearest tenths place.
A. 82.3
B. 89
C. 83
D. 78
Answers
Answer: A) 82.3
Step-by-step explanation:
Mean= average
To find mean, you add up all the numbers and divide by the number of numbers.
In this case you do:
(81+78+83+89+80+87+78) ÷ 7
81+78+83+89+80+87+78
=576
Now, divided by 7
576 ÷ 7
= 82.2857142857
Round to nearest tenths place
= 82.3
