My teacher is gonna kill me. PLEASE HELP
Answer:
It should be C I believe
Step-by-step explanation:
The equation 78+(-6)-5 would equal 67. Which makes it at a standard 78 degrees + -6 which then lowers to 72 degrees. Then after that another 5 which should make it 67. Sorry if that's wrong. Hopefully not. :)

Allan has to make a delivery that is 1200 miles away. By law, he can only drive his truck for 20 hours without taking a break. What must
Allan's average speed be if he wants to make the delivery before he has to take a break
Answer:
Allan has to travel at 60mph if he wants to make the delivery before a break.
Step-by-step explanation:
when you think about it, speed is measured in miles an hour or mph so you have to figure out the speed in miles per hour that he will have to travel, its as simple as dividing 1200/20=60 becuase that gives you the miles per hour seeing how many times 20 can go into 1200.
Answer:
60mph

Which of the following statements is not true about the graph of a system of equations with infinitely many solutions? please answer correctly!
Answer:
The lines will have one positive y-intercept and one negative y-intercept is not true about the graph of a system of equations with infinitely many solutions.
Step-by-step explanation:
A system of equations with infinitely many solutions suggests on the graph, the equations will appear to be the same (they will look like one graph) because all points on each equation are equal. This suggests that it's impossible for the y-intercepts to be different, which is why the "lines will have one positive y-intercept and one negative y-intercept " is a false statement.

Last year, the average number of absences in schools was 9 students per day. This year the average number is 6 students per day. What is the percent of decrease in student absences this year?
Answer:
The percent of decrease is 33.3... percent
Step-by-step explanation:
9 - 6 = 3
3 ÷ 9 = 0.3...
0.3... x 100 = 33.3...
The percent of decrease in student absences this year is 33.33%
What is percentage?The percentage is a fraction or a ratio in which the value of the whole denominator is always 100.
Given that the average number of absences in schools was 9 students per day.
This year the average number is 6 students per day.
We need to find the percent of decrease in student absences this year,
So, the percentage of decrease = 9 - 6 / 9 × 100%
= 1/3 × 100
= 33.33%
Hence the percent of decrease in student absences this year is 33.33%

Answer:
1) 36
2) 190
3) 72 units
Step-by-step explanation:
1) 2x4 = 8 units area for rectangle
(4-2) x4 /2 = 4 units
6 x 4 = 24 units
8 + 4 + 24 = 36
2) 3 x 10 / 2 = 15 units
5 x 10 /2 = 25 units
15 x 10 = 150 units
150 + 25 + 15 = 190 units
3) 6 x 3 / 2 = 9 units
6 x 9 = 54 units
6 x 3 / 2 = 9 units
9 + 9 + 54 = 18 + 54 = 72 units

A function is shown g(x)=96.2(4)(x+2.5). The function g can be rewritten as the function h in the form h(x)=a(4)x. What is the value of a in the function h(x)?
I already know the answer, but I need the step-by-step. Thank you!
Answer:
96.2+240.5/x
Step-by-step explanation:
g(x)=96.2(4)(x+2.5)
h(x)=[96.2(x+2.5)](4)--------------Calculate[96.2(x+2.5)] first
h(x)=(96.2x+240.5)(4)
h(x)=x(96.2+240.5/x)(4)----------bring out X,So 96.2x+240.5 is divided by x
h(x)=(96.2+240.5/x)(4)x
h(x)=a(4)x
so a=96.2+240.5/x
The value of a is 96.2 + 240.5/x.
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).
Given g(x) = 96.2(4)(x+2.5),
and h(x) = a(4)x,
to find a
h(x) = [96.2(x + 2.5)](4)--------------Calculate[96.2(x+2.5)] first
h(x) = (96.2x + 240.5)(4)
h(x) = x(96.2 + 240.5/x)(4)--------bring out x,So 96.2x+240.5 is divided by x
h(x) = (96.2 + 240.5/x)(4)x
h(x) = a(4)x
so a = 96.2 + 240.5/x
Hence value of a = 96.2 + 240.5/x

The distance from Charlotte to Asheville is about 120 miles. If R.C. has two hours to make the trip, but drives 50 mph for the first 60 miles, how fast must R.C. go on the second half of the trip to reach Asheville in time?
A. 70 mph
B. 75 mph
C. 77.2 mph
D. none of these
Answer:
B. 75 mph
Step-by-step explanation:
d - distance
v - velocity
t - time
d = 120 miles
t = 2 hrs
1st 60 miles :
[tex]v = \frac{d}{t} [/tex]
[tex]t = \frac{d}{v} [/tex]
[tex]t = \frac{60}{50} [/tex]
[tex]t = 1.2 \: hrs[/tex]
[tex]t = 1.2 \times 60[/tex]
[tex]t = 72 \: minutes[/tex]

It took 72 minutes for him to travel the first 60 miles. To get the remaining time:
[tex]t = 120 - 72[/tex]
[tex]t = 48 \: minutes[/tex]
[tex]t = 0.8 \: hrs[/tex]
For the Velocity:
[tex]v = \frac{d}{t} [/tex]
