During a 12-hour period, the
temperature dropped 48º.
How many degrees did the
temperature drop each hour?
Answer:
4 degrees every hour
Step-by-step explanation:
Since it was 48 degrees over a total of 12 hours we can do:
48 / 12 = 4 degrees.
It may be presented as -4 degrees since it is dropping in tempature therefore making it negative.

First, make the mixed numbers into improper fractions:
29/2 x 32/3
Simlify by cross cancelling if you can:
29/1 x 16/3
Then, multiply:
29/1 x 16/3 = 29 x 16/1 x 3 = 464/3
Finally, turn the new improper fraction into a simplified mixed number:
464/3 = 154 2/3
The area is 154 2/3 m²

i don’t understand at all
Answer:
26
Step-by-step explanation:
It says find f(f(2)), so we need to find f(2) and then input that into the same function. f(2)=5 so then we input that into the function again and get 26. Boom.
Answer:
26
Step-by-step explanation:
Ok first u find f(2) so for that u have to input 2 into the value of x. So 2^2 +1 =5
When we get 5 we input THAT into f(x)
So:
F(5) = 5^2 +1
=26

A dance academy charges $24 per class and a one time registration fee of $15. A student paid a total of $687 to the academy. Find the number of classes the student took.
Answer:
The student took 28 classes
Step-by-step explanation:
What I did was minus $15 from the $687 total, cause $15 is only a one time registration fee, then 687-15=672, so then I divided 672 by the cost per class, so $24, 672 divided by 24 equals to 28, so the student took 28 classes.

Jane is solving the equasion -2x + 4 = 18. She tells her partner that they should add two to both sides first since that is the inverse of -2. Did Jane start this equation correctly? Explain your reasoning
Answer:
No
Step-by-step explanation:
Given
- 2x + 4 = 18
note the inverse of - 2 is - [tex]\frac{1}{2}[/tex] not - 2
However , the first step is to isolate the term in x by subtracting 4 from both sides.
- 2x = 18 - 4 = 14 ( divide both sides by - 2 )
x = - 7

Answer:
x = 11
Step-by-step explanation:
if we need to find the value of x then we need to
5x + 10 = 65 ( Vertically opposite angles are same )
5x = 65 -10
5x = 55
x = 55/5
x = 11
Answer:
x=11
Step-by-step explanation:
5x+10=65
5x=65-10
5x=55
5x÷5=55÷5
x=11
From 1985 through 1995, the yearly gross farrm revenue (in millions) in the United States can be modeled by the function R(t)=-t^2+7t+159 and the yearly farm cost (in millions) in the United States can be modeled by the function c(t)=t^2+131 where t is the number of years since 1985. Write a new function, P(t), that models the yearly profit after 1985
The profit function is simply the difference between the revenue function and the cost function. The profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]
Given that:
[tex]R(t) = t^2 + 7t + 159[/tex]
[tex]c(t) = t^2 + 131[/tex]
The profit function P(t) is calculated as follows:
[tex]P(t) = R(t) - c(t)[/tex]
So, we have:
[tex]P(t) = t^2 + 7t + 159 - (t^2 + 131)[/tex]
Open brackets
[tex]P(t) = t^2 + 7t + 159 - t^2 - 131[/tex]
Collect like terms
[tex]P(t) = t^2- t^2 + 7t + 159 - 131[/tex]
[tex]P(t) = 7t + 28[/tex]
Hence, the profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

find the value of a if the line joining the points (3a,4) and (a,-3) has a gradient of 1
Recall that the slope or gradient of a line segment through two points is the ratio of the change in the y coordinate to the change in the x coordinate.
If the gradient is 1, then
1 = (-3 - 4) / (a - 3a)
Solve for a :
1 = -7 / (-2a)
1 = 7/(2a)
2a = 7
a = 7/2
