find the missing endpoint endpoint h (-1,0) midpoint p(0,-1)
Answer:
Step-by-step explanation:
Let the other end point be (a,b)
Then the midpoint p(0,-1) is between the two end points (-1,0) and (a,b)
So
(0,-1) = ( (-1+a)/2 , (0+b)/2)
So we have
0 = (-1 +a) /2
0 = -1 + a
a =1
and
-1 = (0+b)/2
-2 = 0+b
b = -2
So the other end point is ( 1, -2)

Monique has 12$ in her account
seven pints of water are needed to water each square foot of lawn. At least how many gallons of water are needed to water a lawn 12 feet by 16 feet.
Find total area: 12 x 16 = 192 square feet.
7 pints are needed for each square foot , multiply total square feet by 7 pints to find total pints needed:
192 x 7 = 1,344 total pints.
1 gallon = 8 pints.
Divide total pints needed by 8 to get gallons:
1,344 / 8 = 168
168 gallons are needed

Elsa got a prepaid debit card with $15 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 7 cents per yard. If after that purchase there was $12.83 left on the card, how many yards of ribbon did Elsa buy?
We need to find the yards of ribbon that Elsa bought with her debit card.
The amount of ribbon that Elsa bought was 31 yards.
Initial amount which is present on the card is [tex]\$15[/tex]
Amount left after spending is [tex]\$12.83[/tex]
Amount spent on ribbon is [tex]15-12.3=\$2.17[/tex]
Converting to cents
[tex]2.17\times 100=217\ \text{cents}[/tex]
Cost of one yard of ribbon is [tex]7\ \text{cents}[/tex]
[tex]1\ \text{yd}=7\ \text{cents}\\\Rightarrow 1\ \text{cent}=\dfrac{1}{7}\ \text{yd}\\\Rightarrow 217\ \text{cents}=\dfrac{217}{7}=31\ \text{yd}[/tex]
The yards of ribbon that Elsa bought is [tex]31\ \text{yards}[/tex].

Cameron has $720 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
He buys a new bicycle for $200.75.
He buys 4 bicycle reflectors for $12.29 each and a pair of bike gloves for $20.49.
He plans to spend some or all of the money he has left to buy new biking outfits for $70.25 each.
Write and solve an inequality which can be used to determine xx, the number of outfits Cameron can purchase while staying within his budget.
The inequality which can be used to determine x, the number of outfits Cameron can purchase while staying within his budget is 720 ≤ 270.4 + 70.25x
Given:
Amount with Cameron = $720
Cost of new bicycles = $200.75
Cost of 4 bicycle reflectors = $12.29 × 4
= $49.16
Cost of bike gloves = $20.49
Cost of new banking outfit = $70.25
let
number of outfits = x
The inequality:
720 ≤ 200.75 + 49.16 + 20.49 + (70.25 × x)
720 ≤ 270.4 + 70.25x
720 - 270.4 ≤ 70.25x
449.6 ≤ 70.25x

A round cake has a diameter of 10 inches and height of 5 inches. What is the volume of the entire cake? Round to the nearest tenth
If the cake is cut into 6 equal pieces, what is the volume of the cake after one piece has been removed ? Round to the nearest tenth
Answer:
1) the volume of the entire cake is ≈ 392.5 cubic inches
2) the volume after 1/6 of it has been removed is ≈ 327.1 cubic inches
Step-by-step explanation:
1) Formula for a cylinder = π r^2 h
First, find the area of the base of the cake (doing π r^2)
A = π r^2
A = 3.14 · 5^2
A = 3.14 · 25
A ≈ 78.5 in^2
Next, multiply the area of the base by the height of the cake (multiplying π r^2 by h)
78.5 · 5 = 392.5 in^3
2) Just divide 392.5 by 6 and subtract what you get from 392.5.
392.5/6 ≈ 65.4
392.5 - 65.4 = 327.1 in^3

M is the midpoint of CD. Given the coordinates of one endpoint C(10,-5) and the midpoint M(4, 0), find the coordinates of the other endpoint D of CD.
Answer:
D(-2, 5).
Step-by-step explanation:
We are given that M is the midpoint of CD and that C = (10, -5) and M = (4, 0).
And we want to determine the coordinates of D.
Recall that the midpoint is given by:
[tex]\displaystyle M = \left(\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2}\right)[/tex]
Let C(10, -5) be (x₁, y₁) and Point D be (x₂, y₂). The midpoint M is (4, 0). Hence:
[tex]\displaystyle (4, 0) = \left(\frac{10+x_2}{2} , \frac{-5+y_2}{2}\right)[/tex]
This yields two equations:
[tex]\displaystyle \frac{x_2 + 10}{2} = 4\text{ and } \frac{y_2 - 5}{2} = 0[/tex]
Solve for each:
[tex]\displaystyle \begin{aligned}x_2 + 10 &= 8 \\ x_2 &= -2 \end{aligned}[/tex]
And:
[tex]\displaystyle \begin{aligned} y_2 -5 &= 0 \\ y_2 &= 5\end{aligned}[/tex]
In conclusion, Point D = (-2, 5).
