A helicopter flies 240 miles in 2 hours 30 minutes.
Calculate the average speed, in mph, of the helicopter.
Answer:
96 mph is the answer
The average speed is 96 mph
What is Average speed?The average speed is the total distance traveled by the object in a particular time interval.
Given:
d= 240 miles
t = 2 hours 30 minutes.
t= 2.5 hours
Average speed= distance/ time
= 240/2.5
= 96 mph

What is the solution to the linear equation? d – 10 – 2d + 7 = 8 + d – 10 – 3d
Answer:
d = 0.33
Step-by-step explanation:
First off, you want to get like terms next to each other. We'll move the numbers with variables on one side and normal numbers on the other. Since we're changing the sides of the equal sign they're on, this also changes whether their positive or negative.
d - d - 2d + 3d = 10 -7 + 8 - 10
Now that they're together, we can add or subtract them. The variables without numbers can be ones for this equation.
3d = 1
Now we divide 1 by 3 to find what d equals.
3d/3 = 1/3
d = 0.33
If Maggie saves 10% off a t-shirt that normally costs $13 and 25% off a pair of boots that normally cost $40, how much in total did she save?
Answer:
Maggie saved $11.30 Dollars
Step-by-step explanation:
The answer is 11.30 because 10% of 13 is 1.3 because 13 divided by 10 is 1.3
and 25% of 40 is 10. So, 10 plus 1.3 is 11.30 dollars

How does the graph of f (x) = |x| compare with the graph of g (x) = -1/2 |x|?
Answer:
The graph of f(x) = |x| is a v-shape and doesn't cross over the x-axis.
The graph of g(x) = -1/2|x| is still a v-shape, but it's upside-down and a bit wider. This is because of the coefficient in front of the |x|. The negative sign flips the graph of |x| and the 1/2 makes the slope smaller, therefore the graph is less steep.

Mrs. Barker bought some books at a book sale, including 4 paperback books. 20% of all the books she bought were paperback. How many books did Mrs. Barker buy in all?
Answer:
20
Step-by-step explanation:
Number of paperback books = 4
Percentage of total books that were paperbacks = 20%
Let total number of books = x
Hence,
20% of total books = paperback books
20% of x = 4
0.2 * x = 4
0.2x = 4
0.2x / 0.2 = 4 / 0.2
x = 20
Total number of books = 20

If QR is 17 more than twice x, RS is 19 less than six times x, and QS is one less than four times x, find x and the measure of each side
Complete question :
triangle QRS is an equilateral triangle. If QR is seventeen more than twice x, RS is 19 less than six times x, and QS is one less than four times x, find x and the measure of each side.
Answer:
x = 9
All sides have 35 units length
Step-by-step explanation:
Recall: Equilateral triangles have 3 sides, all of equal length.
QR = 2x + 17
RS = 6x - 19
QS = 4x - 1
Take :
QR = RS = QS
To find x
QR = RS
2x + 17 = 6x - 19
2x - 6x = - 19 - 17
-4x = - 36
x = 9
QR = 2(9) + 17 = 35
RS = 6(9) - 19 = 35
QS = 4(9) - 1 = 35

Solve x
X-1/2=1/10
Answer:
3/5 (Already there but I wanted to put an explanation)
Step-by-step explanation:
first you want to change the 1/2 to work better with the 1/10. The way you can do is change the 1/2 to be 5/10 by multiplying both sides of the fraction by 5 so that it is out of 10 rather than out of 2. you then add 5/10 to 1/10 to get x=6/10. since 6/10 can be simplified by 2, you divide both sides of the fraction by 2 to get 3/5=x

if a function has a verticale asymptote at a certain x-value, then the function is at the value
Answer:
We conclude that If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.
Step-by-step explanation:
If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.
For example, let the function
[tex]f\left(x\right)\:=\frac{x+3}{x-3}[/tex]
It is clear that the given function becomes undefined at x = 3 in the denominator.
i.e. 3-3 = 0
It means, the function can not have x = 3, otherwise, the function will become undefined.
In other words, if the function has a vertical asymptote at x = 3, then the function is undefined at the value.
Therefore, we conclude that If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.

Check all that apply.
HELP ME NOW PLEASE DONT GIVE A FAKE ANSWER PLEASEEEEEEEEEE
Answer:
y = 22; x = 8
y > x
Step-by-step explanation:
A larger number is double the sum of 3 and a smaller number. The larger number is 2 less than 3 times the smaller number. If y represents the larger number and x represents the smaller number, which equations model the situation? Check all that apply.
Let
Smaller Number = x
Larger number = y
larger number is double the sum of 3 and a Smaller number
Sum of 3 and a smaller number = 3 + x
y = 2(3 + x)
y = 6 + 2x (1)
Also
y = 3x - 2 (2)
Equate the equation of the larger number
6 + 2x = 3x - 2
6 + 2 = 3x - 2x
8 = x
x = 8
Substitute x = 8 into (1) to find y
y = 6 + 2x (1)
y = 6 + 2(8)
= 6 + 16
= 22
y = 22
y = 22; x = 8
Therefore,
y > x

Answer:
(x + y)(a + 9)
Step-by-step explanation:
Here, we want to factorize the polynomial
We can do this by taking together like terms
Thus. we have that;
9x + ax + ay + 9y
= x(a + 9) + y(a + 9)
= (x+y)(a+ 9)
