Answer:
C(50;-20)
Step-by-step explanation:
The question is asking for the midpoint of the line.
The triangle is formed by placing a line directly from the y-axis to the x-axis.
The midpoint theorem is[ (x1+x2)/2 ; (y1+y2)/2 ].
your coordinates at A is (0;-40), because the x value is 0 on the line as shown in the diagram above point A.
Your coordinates for B are (100;0)
C[(x1+x2)/2 ; (y1+y2)/2 ]
C [(0+100)/2 ; (-40+0)/2 ]
C[ 100/2 ; -40/2]
C (50 ; -20)
Gloria is painting a wall in her bedroom. The dimensions of the wall measure 14 feet by 11 feet.
The gallon of paint that she purchased will cover 400 square feet. Does she have enough paint
to do two coats on the wall? Justify your answer.
Answer:
yes she does
Step-by-step explanation:
14*11=154
for 2 coats you need twice that which is 308 square feet
she purchased enough paint to cover 400 square feet so she would have plenty of paint to do 2 coats

Calculate your monthly payments and total amounts paid. Use the formula for loan amortization below to figure out how much each payment will be. “Amortization” means paying off the loan in a series of equal installments. You’ll need to know the amount of the loan, the monthly interest rate, and the number of months you’ll be making payments in order to make the calculation.
A=P*(r(1+r)^{n})/((1+r)^{n}-1).

Consider the problem: 1/2 ÷ 5. Which model correctly represents this expression? How do you know?
Answer:
[tex]\frac{1}{10}[/tex]
Step-by-step explanation:
Find p(b|c). p(b|c) = startfraction 9 over 34 endfraction = 0.26 p(b|c) = startfraction 9 over 24 endfraction = 0.38 p(b|c) = startfraction 9 over 70 endfraction = 0.13 p(b|c) = startfraction 9 over 58 endfraction = 0.16
The expression P(B|C) is an illustration of probability, and the value of P(B|C) is 0.38
How to determine the value of the probability expression?From the question, we have the following highlights:
n(B and C) = 9
n(C) = 24
The equation to calculate the probability expression is:
P(B|C) = n(B and C)/n(C)
Substitute known values
P(B|C) = 9/24
Evaluate the expression
P(B|C) = 0.38
Hence, the value of P(B|C) is 0.38

Electric utility poles in the form of right cylinders are made out of wood that costs $25.46 per cubic foot. Calculate the cost of a utility pole with a diameter of 1.5 ft and a height of 30 ft. Round your answer to the nearest cent.
Answer:
$ 1349.746624
Step-by-step explanation:
The volume of a cylinder
The formula for calculating the volume of a cylinder is expressed as:
V=πr²h
where:
r is the radius
h is the height
Given the following parameters
r = d/2 = 1.5/2 = 0.75ft
h = 30ft
Get the volume of the cylinder
V=π(0.75)²(30)
V= 53.0144...ft³
If the wod costs $25.46 per cubic foot, hence the cost of the wood will be 53.0144*25.46 = $ 1349.746624

5. 11
6. 13
8. n
10. 21
Answer:
n = 17
Step-by-step explanation:
Method 1The difference between the 5th and 6th terms is 13 - 11 = 2
Therefore, the next term can be found by adding 2 each time.
If we continue with this sequence, we get:
5 = 11
6 = 13
7 = 13 + 2 = 15
8 = 15 + 2 = 17
9 = 17 + 2 = 19
10 = 19 + 2 = 21
So n = 17
-------------------------------------------------------------------------------------
Method 2Arithmetic sequence
General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]
where:
[tex]a_n[/tex] is the nth terma is the first termd is the common difference between termsGiven terms of the sequence:
[tex]a_5=11\\a_6=13\\a_8=n\\a_{10}=21[/tex]
The common difference can be found by subtracting one term from the next term:
[tex]d=13-11=2[/tex]
To find a, substitute the found value of d into the equation for one of the given terms:
[tex]\begin{aligned}a_5 =a+(5-1)2 & =11\\ a+8 & =11\\ a & = 3\end{aligned}[/tex]
Therefore, the formula to find the nth term is:
[tex]\implies a_n=3+(n-1)2[/tex]
[tex]\implies a_n=2n+1[/tex]
So, the 8th term is:
[tex]\implies a_8=2(8)+1=17[/tex]

Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.
Answer:
y = -1/2 x + 10.
Step-by-step explanation:
The line q has the same slope (-1/2) as line p as the 2 lines are parallel.
Equation of the line q:
y - 8 = -1/2(x - 4)
y - 8 = -1/2x + 2
y = -1/2 x + 2 + 8
y = -1/2 x + 10.

[tex]5x+3y=7\\3x-5y=-23[/tex]
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
let's solve ~
The given equations are :
[tex]\qquad \tt \dashrightarrow \:5x + 3y = 7 \: \: \: \: \: \: \: \: \: \: \: \: - (1)[/tex]
and
[tex]\qquad \tt \dashrightarrow \:3x - 5y = - 23 \: \: \: \: \: \: - (2)[/tex]
Now, let's multiply equation (1) by 5 and equation (2) by 3 ~
we will get the results as :
[tex]\qquad \tt \dashrightarrow \:25x + 15y = 35 \: \: \: \: - (3)[/tex]
[tex]\qquad \tt \dashrightarrow \:9x - 15y = - 69 \: \: \: - (4)[/tex]
Now, add equation (3) and (4) :
[tex]\qquad \tt \dashrightarrow \:25x + \cancel{ 15y} + 9x - \cancel{15y }= 35 + ( - 69)[/tex]
[tex]\qquad \tt \dashrightarrow \:34x = - 34[/tex]
[tex]\qquad \tt \dashrightarrow \:x = - 1[/tex]
Now, since we got the value of x, let's evaluate y~ by using equation (1) :
[tex]\qquad \tt \dashrightarrow \:5x + 3y = 7[/tex]
[tex]\qquad \tt \dashrightarrow \:5( - 1)+ 3y = 7[/tex]
[tex]\qquad \tt \dashrightarrow \:3y - 5 = 7[/tex]
[tex]\qquad \tt \dashrightarrow \:3y = 12[/tex]
[tex]\qquad \tt \dashrightarrow \:y = 4[/tex]
Hence, value of y is 4

B. (x, y) ⇒ (x, -y)
Step-by-step explanation:
When a point is reflected over the x-axis, it is moved along a vertical line to the same distance on the other side of the x-axis.
The x-coordinate of a point identifies its distance from the y-axis--the vertical line it is on. The y-coordinate identifies its distance from the x-axis. Changing the sign of the y-coordinate moves the point to the same distance on the other side of the x-axis--reflecting it over the x-axis.
