Answer:
(7,4)
Step-by-step explanation:
The midpoint formula is expressed as:
M(X, Y) = {(x2+x1)/2, (y2+y1)/2
Given the coordinates of the midpoint
M(2.5, -1.5)
Endpoint A(-2, -7)
Required
Endpoint B
From the formula;
X = x2+x1/2
Given
X = 2.5, x1 = -2
Get x2
2.5 = -2+x2/2
5 = -2+x2
x2 = 5+2
x2 = 7
Also
Y = y2+y1/2
-1.5 = -7+y2/2
-3 =-7+y2
y2 = -3+7
y2 = 4
Hence the coordinate of the endpoint B (x2,y2) is (7,4)

The Ride-It Store rents bicycles.The cost is $8.50 for 1 hour, $13.65 for 2 hours,$18.80 for 3 hours, and $23.95 for 4 hours.If the pattern continues, how much will it cost Nate to rent a bike for 6 hours?
Answer:
in six hours it would be $34.25
Step-by-step explanation:
The computation of the total cost for 6 hours is shown below:
For one hour it would be $8.50
For two hours
= $13.65 - $8.50
= $5.15
For three hours
= $18.80 - $13.65
= $5.15
For four hours
= $23.95 - $18.80
= $5.15
For five hours
= $23.95 + $5.15
= $29.10
For six hours
= $29.10 + $5.15
= $34.25
Hence, in six hours it would be $34.25
An office uses paper drinking cups in the shape of a cone, with dimensions as shown. To the nearest tenth of a cubic inch, what is the value of each drinking cup?
*see attachment for the dimensions of the cone given.
Answer:
7.9 in³
Step-by-step explanation:
Given:
Height of cone = 4 in.
Diameter of cone = 2¾ in
Radius (r) = ½ of 2¾ = 1.375 in
Required:
Volume of the cup
Solution:
Volume of the cup = volume of a cone
Volume of a cone = ⅓πr²h
Plug in the values of π, r and h into the formula.
Volume = ⅓*3.14*1.375²*4 = 7.9 in³ (approximated to the nearest tenth)

If x = 14, which equation is true?
A.3 ( 20 − x ) = 44
B.3 ( 12 − x ) = 6
C.2 ( x − 3 ) = 22
D.2 x − 3 = 22
Answer:
C. 2 ( x − 3 ) = 22Step-by-step explanation:
if x = 14
2 ( x − 3 ) = 22
2 (14 - 3) = 22
2 (11) = 22
22 = 22
therefore, the answer is C.
The temperature of a liquid in an experiment starts at 0 degrees Celsius. The experiment calls for the temperature of the liquid to change at a rate of –0.6 degree Celsius per minute. How long will it take for the liquid to reach –10.5 degrees Celsius? 2Points Remember to divide to find the minutes.
Answer:
It will take 17.5 minutes or 17 minutes and 30 seconds to reach -10.5 degrees celsius
Step-by-step explanation:
Starting at 0 degrees, we have a change of -0.6 degree celsius per minute
We want to know how long it will take for the liquid to reach - 10.5 degrees Celsius
The total difference between the two is;
-10.5 - 0 = -10.5
The change per minute is -0.6
So the number of minutes it will take will be;
-10.5/-0.6 = 17.5 minutes

Delilah and a group of friends had excellent service at a restaurant. They would like to give the server a 25 percent gratuity on their $140 bill.
Answer:
Here we want to calculate the 25% of $140.
Well, first we assume that:
$140 = 100%.
Now, assuming that, we can write the equation:
X = 25%
Where X is the 25% of $140.
Then we have the equations:
$140 = 100%
X = 25%
Let's take the quotient between these equations:
$140/X = (100%/25%)
Now let's solve this for X:
X = (25%/100%)*$140 = 0.25*$140 = $35
Then the tip will be of $35
35
you have to split 140 into 4 parts which is division
your expression would be 140 divided by 4

Suppose that y is inversely proportional to the 4th power of x, and that y=15 when x=5. What is y when x=7? Round your answer to two decimal places if necessary.
Answer:
y = 3.91 when x =7
Step-by-step explanation:
y = k / x⁴
Where,
k = constant of proportionality
y=15 when x=5
y = k / x⁴
15 = k / 5⁴
Cross product
15 × 5⁴ = k
15 × 625 = k
9,375 = k
What is y when x=7?
y = k / x⁴
= 9,375 / 7⁴
= 9,375 / 2401
= 3.9046230737192

y = 3.91

Store A charges $1,200 for repairs with a 6 percent sales tax. Store B charges $1,350 with a 7 percent sales tax. Explain how you would determine the amount of money saved by using Store A instead of Store B?
Step-by-step explanation:
Store A:
6% of 1,200 is 72
72 + 1,200 = 1,272
Thus, store A has a total of 1,272
Store B:
7% of 1,350 is 94.5
94.5 + 1,350 = 1444.5
Thus, Store B has a total of 1444.5
1444.5 - 1,272 = 172.5
Thus, Store A is cheaper.
Answer:
sales tax- rate×original amount
A- 6/100(1200)=72
B- 7/100(1350)=94.5

A family wishes to determine the distance from their home to the nearest park. On a coordinate grid, the house sits at (0, 0), and the park at (16, 11). Using 1 unit = 10 yards, which vector represents the path from the house to the park, and what is the actual distance between them?
components: (16,11), distance: 19.42 yards O components: (16,11), distance: 194 16 yards O components: (120,110), distance: 19.42 yards O components: (160,10), distance: 194.16 yards
Answer:
components: LeftAngleBracket 16, 11 RightAngleBracket distance: 194.16 yards
Step-by-step explanation:
get her done!!! Correct on Edge 2020
The vector represents the path from the house to the park is components: {16,11} and actual distance between them is 194.16 yards. So, option A is correct.
What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
|AC|^2 = |AB|^2 + |BC|^2
In order to find the length of a point to another point that has different y and x points, we will use the pythagorean theorem
(a^2 + b^2 = c^2)
Here, 16 and 11 are the distances from her house,
16^2 + 11^2 = c^2
c^2 = 377
c = 19.416...
Now, we have to convert this to yards;
19.416 x 10 = 194.16 yards
Hence, the vector represents the path from the house to the park is components: {16,11} and actual distance between them is 194.16 yards.
So, option A is correct.
