Answer:
x = 16
Step-by-step explanation:
Supplementary angles = 180
K + L = 180
137 + 3x - 5 = 180
132 + 3x = 180
3x = 180 - 132
3x = 48
x = 48/3
x = 16

HELP! WILL GIVE BRANLIEST!
Answer:
Step-by-step explanation:
z = 119 Vertically opposite angles are equal.
5x + 41 + 119 = 180 5x + 41 and 119 are supplementary.
4x + 160 = 180 Subtract 160 from both sides
4x = 180 - 160
4x = 20 Divide by 4
x = 20/4
x = 5
what is the area of the rectangular piece of wood?
Answer:
2x^2 + 7x + 3 is the area of the rectangular piece of wood.
Step-by-step explanation:
Here,
Length ( l ) = x + 3
Breadth ( b ) = 2x + 1
Formula : -
Ar ( rectangle ) = lb
lb
= ( x + 3 ) ( 2x + 1 )
= x ( 2x + 1 ) + 3 ( 2x + 1 )
= 2x^2 + x + 6x + 3
= 2x^2 + 7x + 3
IF PASSPORT is written as RCUURQTV, then how will BOOKLET be coded?
Answer: DQQMNGV
Step-by-step explanation: Each letter is shifted two letters to the right on a letter strip (a -> b -> c), so BOOKLET would be DQQMNGV.

A consumer affairs investigator records the repair cost for 4 randomly selected washers. A sample mean of $52.63 and standard deviation of $22.01 are subsequently computed. Determine the 80% confidence interval for the mean repair cost for the washers. Assume the population is approximately normal. Step 2 of 2 : Construct the 80% confidence interval. Round your answer to two decimal places.
Answer:
The 80% confidence interval for the mean repair cost for the washers is between $34.60 and $70.66.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 4 - 1 = 3
80% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 3 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.8}{2} = 0.9[/tex]. So we have T = 1.638
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 1.638\frac{22.01}{\sqrt{4}} = 18.03[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 52.63 - 18.03 = $34.60
The upper end of the interval is the sample mean added to M. So it is 52.63 + 18.03 = $70.66.
The 80% confidence interval for the mean repair cost for the washers is between $34.60 and $70.66.
Betsy's high school is putting on a production of a play as a fundraiser for the school's music programs. A local bank has agreed to
allow the school to use a line of credit from which they can withdraw money to pay for the play. Then, any deposits they make at the
bank will be applied to the negative balance of the credit account.
The play cost $2,500.00 to produce, and they intend to sell tickets for $7 each. After the play, Betsy will take the ticket proceeds and
deposit them with the bank. If 559 people attend the play's opening night, what will the balance of the bank account be?

Gina and Marty are selling tickets for the school dance. On Monday, they sold 15 tickets, on Tuesday 23, on Wednesday 20, and on Thursday 32. What was their average daily income if each ticket cost $2.00?
Answer:
$45
Step-by-step explanation:
15×2=30
23×2=46
20×2=40
32×2=64
30+46+40+64=180
180÷4=45
Average=45
Answer:
Their average daily income would be 45 dollars a day.
Step-by-step explanation:
To solve this, add the 15 tickets, 23, 20, and 32 tickets from Monday to Thursday. This should get you a total of 90 tickets. Since each ticket cost 2 dollars, multiply the 90 by 2. This should get you 180. TO find the average, you must divide the total(180) by the amount of days(4) that passed. This should get you 45.
Answer:
45$

A cylinder and a cone have the same volume. The cylinder has a radius of 2 inches and a height of 3 inches. The cone has a radius of 3 inches. Determine the height
Answer:
so lets get the cones volume first the formula for a cone is V=πr2/3
so V=πr2h
3=π·22·3
3≈12.56637
and then the height of the cylinder is 4

17 A plank of wood is 3.6 metres long. 85 cm is sawn off.
How long is the remaining plank?
help please if yo help she will marry you
Answer:
2.75
Step-by-step explanation:
So lets work this out:
First, we will need to convert 85 cm to meters. That would be 0.85 meters.
Now we can take 0.85 meters and subtract it from 3.6. This equals 2.75.
A plank of wood is 3.6 meters long. 85 cm is sawn off. How long is the remaining plank? 2.75 meters

Write the equation in standard form for the circle with center (-7,5) and radius 8
Answer:
64 = (x+7)^2 + (y-5)^2
Step-by-step explanation:
Equation of a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So the equation is: 64 = (x+7)^2 + (y-5)^2
Which of the following is a solution to the equation: y = 7x + -59? Choose all that apply.
Select all that apply:
O (8,-3)
O (9,8)
O (7,-3)
0 (10,5)
Answer:
[tex](a)\ (8,-3)[/tex]
Step-by-step explanation:
Given
[tex]y =7x +-59[/tex]
Required
Select all solutions
[tex](a)\ (8,-3)[/tex]
This implies that:
[tex]x = 8; y=-3[/tex]
So:
[tex]y =7x +-59[/tex]
[tex]-3 =7 * 8 + -59[/tex]
[tex]-3 =7 * 8 -59[/tex]
[tex]-3 =56 -59[/tex]
[tex]-3 =-3[/tex]
The above is a solution:
[tex](b)\ (9,8)[/tex]
This implies that:
[tex]x=9\ y =8[/tex]
So:
[tex]y =7x +-59[/tex]
[tex]8 =7 * 9 + -59[/tex]
[tex]8 =7 * 9 -59[/tex]
[tex]8 =63 -59[/tex]
[tex]8 =4[/tex]
The above is not a solution because [tex]8 \ne 4[/tex]
[tex](c)\ (7,-3)[/tex]
This implies that:
[tex]x=7;\ y=-3[/tex]
So:
[tex]y =7x +-59[/tex]
[tex]-3 = 7 * 7 +-59[/tex]
[tex]-3 = 7 * 7 -59[/tex]
[tex]-3 = 49 -59[/tex]
[tex]-3 = -10[/tex]
The above is not a solution because [tex]-3\ne -10[/tex]
[tex](d)\ (10,5)[/tex]
This implies that:
[tex]x =10; y=5[/tex]
So:
[tex]y =7x +-59[/tex]
[tex]5 = 7 * 10 + -59[/tex]
[tex]5 = 7 * 10 -59[/tex]
[tex]5 = 70 -59[/tex]
[tex]5 = 11[/tex]
The above is not a solution because [tex]5 \ne 11[/tex]
