Triangle JKL has coordinates J(−2, −3), K(−5, −2), and L(−6, −7). The triangle is reflected across the y-axis. (PLS HELPP)
Answer:
J ' (2, -3)
K ' (5, -2)
L ' (6, -7)
The diagram is below
=======================================================
Explanation:
The y axis reflection rule you use is [tex](x,y) \to (-x,y)[/tex]
The x coordinate flips in sign, positive to negative or vice versa.
The y coordinate stays the same.
For example, the point J(-2,-3) moves to J ' (2, -3). The same thing happens to the other points as well.
Check out the diagram below.
An industrial machine produces widgets, but it has a 0.12 defective rate. What is the probability that the machine produces fewer than 3 defective widgets in a production run of 75 items?
A. 0.0035
B. 0.0043
C. 0.0654
D. 0.0432
Answer: Hence required probability = 0.004307
Step-by-step explanation:
Given an industrial machine has 0.12 defective rate and to find probability that fewer than 3 defective widgets run of 75 items,
⇒[tex]P(x < 3)=P(x=2)+P(x=1)+P(x=0)[/tex], since P(x=r)=[tex]_nc_r P^rq^n^-^r[/tex]
Here P=0.12, q=1-p, 1-0.12=0.88, n=75

If ⅙ of a roll of wallpaper covers ¼ of the wall. How many rolls of paper are needed to cover 4 walls?
Answer:
if 1/6 of a roll of paper covers 1/4 of a wall, this means that we will need 4/6 of a roll to cover a whole wall, now the question is asking how many rolls will we need to cover 4 walls, we already know that it takes 4/6 to fill one wall so if we add 4/6+4/6+4/6+4/6 we will get 16/6 or 2 4/6
we will need 16/6 or 2 4/6 of rolls of paper to cover 4 walls

Question shown with image attached.
Answer:
x = 109°Step-by-step explanation:
(x° - 38°) + x + 90° + 90° = 360°
(The sum of the interior angles of any quadrilateral is 360°)
[tex](x - 38) + x + 90 + 90 = 360 \\ x - 38+ x + 180 = 360 \\ x + x + 180 - 38 = 360 \\ 2x + 142 = 360 \\ 2x = 360 - 142 \\ 2x = 218 \\ \frac{2x}{2} = \frac{218}{2} \\ x = 109 \\ [/tex]
The total angle measures a quadrilateral has is 360 degrees and in the problem, we are told that two of the angles are both 90 degrees. So thats 180 degrees out of the way and now we have x+(x-38)=180 which is 2x-38=180 then you add 38 to both sides to get rid of the 38 on the left side and then you end up with 2x=218 so you have to divide both sides by 2 to remove the 2 from x and you would get x=109

Answer:
x = 37
Step-by-step explanation:
2x and 74 are vertically opposite angles and are congruent, so
2x = 74 ( divide both sides by 2 )
x = 37
Step-by-step explanation:
To find the value of x, first, the denominators are made equal by taking the L.C.M. of them.
(3x + 2)/7 + (4(x + 1))/5 = 2/3 * (2x + 1) (45x + 30 + 84x + 84)/105 = (140x + 70)/105
Since both the sides of the equation have the same denominator now, they can be cancelled out.
45x + 30 + 84x + 84 = 140x + 70
The equation can be rearranged by shifting all the x terms on one side of the equation and all the constants on the other side of the equation.
140x - 85x - 45x = 84 + 30 - 70
10x = 44
x = 4.4
Therefore, the value of x is 4.4.
A band that will be the opening act for a concert charges a $500. 00 flat fee as well as 10% of all profits from ticket sales. If the band earns $1,200, how much was made in total ticket sales for the show?.
Using the profit concept to find the ticket sale, then the money made in ticket sales for the show is $7000.
What is profit?The money that you gain by selling something.
Given
A band that will be the opening act for a concert charges a $500 flat fee as well as 10% of all profits from ticket sales.
They earned the profit will be
1200 - 500 = 700
They earned a profit is $700.
$700 is 10% of ticket sales. Then the money made in total ticket sales for the show will be
[tex]\rm Ticket\ Sale = \dfrac{700}{0.1}\\\\Ticket\ Sale = 7000[/tex]
The money made in total ticket sales for the show is $7000.

Step-by-step explanation:
Answer:
Im pretty sure its the graph on the top right
Step-by-step explanation:
the first 2 weeks she worked the graph went up, the last 2 weeks she worked less time, so the graphs will go down, but since she worked 15 hours on the third week, and 13 hours on the first week, the third weeks point doesn't go below the first weeks starting point. anyways i hope thats correct

A triangle has vertices at (−2, −2), (−2, −5), and (−4, −5). The triangle is translated 2 units to the right and rotated 90° clockwise about the origin. What are the coordinates of its image?
( , ), ( , ), ( , ) → ( , ), ( , ), ( , ),
Step-by-step explanation:
translated (shifted) 2 units to the right (positive x direction) creates the points
(-2 + 2, -2) = (0, -2)
(-2 + 2, -5) = (0, -5)
(-4 + 2, -5) = (-2, -5)
and now we rotate these points 90° clockwise around the origin.
that means a positive x turns into a negative y, a negative y into a negative x, a negative x into a positive y, and a positive y into a positive x.
and a 0 just trades places.
therefore,
(0, -2) becomes (-2, 0)
(0, -5) becomes (-5, 0)
(-2, -5) becomes (-5, 2)
so, overall
(-2, -2) becomes (-2, 0)
(-2, -5) becomes (-5, 0)
(-4, -5) becomes (-5, 2)
If three times a number is increased by 24, the result is 16 less than seven times the same number. Find the number.
Answer:
10
Step-by-step explanation:
let x = unknown number
three times x is increased by 24
so 3x + 24
this is equal to 16 less than 7 times x
so 3x + 24 = 7x - 16
we now solve for x
3x + 24 = 7x - 16
add 16 to both sides
3x + 24 + 16 = 7x - 16 + 16
3x + 40 = 7x
subtract 3x from both sides
3x - 3x + 40 = 7x - 3x
40 = 4x
divide both sides by 4
40/4 = 10
4x / 4 =x
x=10
the unknown number is 10

You are ordering pizzas. The pizza cost $18. The sales tax is 6%, and you give a 15% tip. What is the total?
Answer:
$21.94
Step-by-step explanation:
I'm not sure how many pizzas were ordered, but let's say you just got one large pizza that was $18.
First, the sales tax - 6%
$18 + 6% = $19.08
Then you give a 15% tip.
$19.08 + 15% = $21.94
You spend 15 on a meal including tax and want to leave a tip that is 20% of the 15 what is the Total cost with the tip
Answer:
$18.00
Step-by-step explanation:
If the meal is $15.00, 20% of that meal's cost would be $3.00.
$15.00 * .20 = $3.00
Adding the tip to the meal's cost will give you a total cost of $18.00.

Answer:
A. 1.06
B. $6,784
Step-by-step explanation:
I = A - P = $384.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 6400(1 + (0.06 × 1)) = 6784
A = $6,784.00
The total amount accrued, principal plus interest, from simple interest on a principal of $6,400.00 at a rate of 6% per year for 1 year is $6,784.00.

A paratrooper bails out of an airplane at altitude 15,000 ft, then falls freely for 30 seconds, then opens a parachute.
The speed of the parachute is 50ft/s
How to calculate the speed of an objectThe formula for calculating speed is expressed as:
Speed = Distance/Time
Given the following parameters
Distance = 15,000 feet
Time = 30 seconds
Substituting into the formula;
Speed = 1500ft/30s
Speed = 50ft/s
Hence the speed of the parachute is 50ft/s

PLEASE HELP! AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Answer:
117°
Step-by-step explanation:
Start by finding the measure of the angle adjacent to the one marked 101 degrees. Since they are a linear pair, they add up to 180 therefore...
101+y=180
Subtract 101 from both sides...
y=79
Now, using the exterior angle theorem (the exterior angle is equivalent to the sum of the two interior angles that are NOT adjacent to the exterior angle), we can set up an equation to find x...
x=38+79

B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.
C) It will take 5 weeks for her to save $150
Step-by-step explanation:
A) 20 represents the amount of money saved in one month or amount saved per month. This is the slope or rate of change of the function.
B) 50 represents the amount of money already present in the account when she starts saving. This is the y-intercept of the function.
C) The time to reach $150
150 = 20(w) + 50
20(w) = 150 - 50
20w = 100
w = 100/20
w = 5
It will take 5 weeks
