Answer:
The x is equal to 23°.
Step-by-step explanation:
Because any triangle's three angles add up to 180°, all you have to do is add the other two angles together and subtract that sum from 180.
180 - (124 + 33) = 23°

A restaurant offers delivery for their pizzas. The total cost is a delivery fee added to the price of the pizzas. One customer pays $25 to have two pizzas delivered. Another customer pays $58 for five pizzas. How many pizzas are delivered to a customer who pays $80?
Answer:
7
Step-by-step explanation:
We know, slope = rise/ run. We can use this slope formula to find out the value of every pizza.
So, 58-25/( 5-2) = 33/ 3= 11
So, every pizza costs $11
Now, A customer pays $80 for a number of pizzas. So, if we divide 80 by 11 we can find the value of unknown number of pizzas he ordered.
So, 80/11= 7.27
Here, pizzas can't be fraction and cost of a delivery fee is added to the cost. So, we can remove the fraction.
So, the customer ordered 7 pizzas for $80.

pls help answering a b and c
Answer:
a) The very first one where the line starts to the left
b) m=125.82
c) 320.81 thousand dollars
Step-by-step explanation:
a) The point on the graph who corresponds to x=3 years and Salary=$200,000 is the very first one where the line starts to the left
b) If a line is given by Y=mx+b, m represents the slope of the line. In this case, m=125.82 which can be interpreted as the rate of growth of the salary per year in thousands of dollars. A doctor can expect to earn 125.82 thousand dollars more than the previous year.
c) If we use the given regression line Y=125.82x-182.47 and make x=4, we get
y=125.82 (4)-182.47 =320.81 thousand dollars
Solve for m. 12m-15=3(2m+3)
Answer:
m = 4
Step-by-step explanation:
12m - 15 = 3 (2m + 3)
12 m - 15 = 6m + 9
12m - 6m - 15 = 6m - 6m + 9
6m - 15 = 9
6m - 15 + 15 = 9 + 15
6m = 24
(1/6) 6m = 24 (1/6)
m = 4

roberto has 200$ to spend on tickets to the hockey game . since each ticket costs $30, that means he could purchase 6.67 tickets with his $200. how many tickets can he buy ?
Answer:
6 tickets
Step-by-step explanation:
you can't round it so just says 6 tickets with left over money
The number of tickets Roberto can buy with his $200 is 6 tickets.
The total amount Roberto has to spend on tickets = $200.
The cost of each ticket = $30.
We need to find the number of tickets Roberts can buy for the hockey game.
Total amount to spend on ticket = $200.
Cost of each ticket = $30.
The number of tickets possible to buy with $200 :
= 200 / 30
= 6.67 tickets.
We can not have 6.67 tickets so we can say 6 tickets.
Since each ticket cost $30, the total cost for the ticket is :
= 6 x $30
= $180
So after buying 6 tickets Roberto will be left with $20.
The number of tickets Roberto can buy with his $200 is 6 tickets.

Shen the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the other (not both). On Friday there were 3 clients who did Plan A and 5 who did Plan B. On Saturday there were 6 clients who did Plan A and 2 who did Plan B. Shen trained his Friday clients for a total of 10 hours and his Saturday clients for a total of 10hours. How long does each of the workout plans last?
To find the duration of workout plans A and B offered by Shen, we set up a system of linear equations and solved them. Both plans last 1.25 hours each.
Explanation:Let us denote the duration of workout Plan A as A hours and Plan B as B hours. We can use the provided information to set up a system of linear equations representing the total training time on each day. On Friday, 3 clients did Plan A and 5 did Plan B for a total of 10 hours, leading to the equation 3A + 5B = 10. On Saturday, 6 clients did Plan A and 2 did Plan B for a total of 10 hours, resulting in the equation 6A + 2B = 10.
To solve this system of equations, we can use substitution or elimination. Multiplying the first equation by 2 gives us 6A + 10B = 20. Then we can subtract the Saturday equation from this to find the value of B:
(6A + 10B) - (6A + 2B) = 20 - 108B = 10B = 1.25 hoursNow that we know the duration of Plan B, we can plug this into either of our original equations to find the duration of Plan A. Let's use the Friday equation for this purpose:
3A + 5(1.25) = 103A + 6.25 = 103A = 3.75A = 1.25 hoursAs it turns out, both workout plans last the same amount of time, 1.25 hours each.
A rectangle has an area of x2 + x-6 and a width of x-2. What is the length of the
rectangle?
Answer:
The length of the rectangle is x+3.
Step-by-step explanation:
(x^2+x-6)/(x-2)=x+3
Because (x-2)(x+3)=x^2-2x+3x-6=x^2+x-6, which is the area.
Since the width is x-2, you can find the length very easily.
Mara's family is driving to her grandmothers' house. The family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m. Write an equation that Mara can use to determine their average rate of travel, R, rounded to the nearest mile per hour.
Use the given numbers and operations to complete an equation.
Mara's family's average rate of travel, R, is calculated by dividing the total distance of 239.4 miles by the total time of 4.5 hours and then rounding to the nearest mile per hour.
To determine Mara's family's average rate of travel, R, you should start by calculating the total travel time. They started at 9:10 a.m and ended at 1:40 p.m, which is a span of 4 hours and 30 minutes, or 4.5 hours when converted to decimals to match the units of the distance traveled. Now use the formula for average speed, which is distance divided by time.
So, R = total distance / total time.
Substitute the given values into this formula to arrive at R = 239.4 miles / 4.5 hours. To find the average rate of travel, rounded to the nearest mile per hour, you would complete the division and then round the result.
Example Equation:
R = 239.4 miles / 4.5 hours

Two skaters are racing towards the finish line of the race.the first Skater has a 40 meter lead and is traveling at a rate of 12 meter.the second skater is traveling at a rate of 14 meter per second.how long will it take for the second skater to pass the first skater?
Answer:
20 seconds
Step-by-step explanation:
The distance to cover between the lead skater and trailing skater is 40 meters
The lead skater's rate is 12 m/s
The trailing one's rate is 14 m/s
So, we can say:
second skater is accelerating, or covering up the distance, in 14 - 12 = 2 m/s
So, at a rate of 2 meters per second, how long would it take to cover 40 meters??
We use the distance formula, substitute the known and solve for unknown.
Distance Formula = D = RT
Where
D is distance
R is speed/rate
T is time
We know
r = 2 m/s
d = 40 m
t = ?
Now,
D = RT
40 = 2t
t = 40/2
t = 20 (seconds)
Hence,
it will take 20 seconds for the second skater to catch up (pass)

For a certain value of k, the system
[tex]x+y+3z=10,\\
-4x+2y+5z+7,\\
kx+z=3,[/tex]
has no solutions. What is the value of k?
The value of k that makes the system of equations have no solution is k = -0.25. This is because -0.25 makes the third equation parallel to the first two, resulting in no intersection or solution to the system.
Explanation:The system of equations provided relates to the concept of systems of linear equations in mathematics. When a system of equations has no solution, it means the graphs of the equations do not intersect. To find the value of k where there is no solution, we determine when the planar coefficients of each equation are proportional. This occurs when the two planes are parallel and hence, do not intersect.
By examining the coefficients, we notice that dividing the coefficients from the first equation by -4 gives us the coefficients of the second equation, meaning the first two equations represent the same plane. Thus, k does not affect the first two equations. For the system to have no solutions, the third plane must be parallel to the first two, meaning the coefficients must have a ratio equal to k. If we set the coefficients from the third equation with the coefficients from the first one, we end with the proportion k/1 = 1/-4 = 3/10. Solving for k gives us a value of -0.25.

Jaxon's start up business makes a profit of $450 during the first month. however the company records a profit of -$60 per month and profit of $125 for the final month. what is the total profit for the six month of Jaxon's business.
Answer:
The total profit for the six month of Jaxon's business is $335.
Step-by-step explanation:
Here, the profit in the business for the first month = $450
Now, the company suffers for loss of $ 60 per month for 4 months.
SO, the total loss in 4 months = 4 x ( loss in 1 month)
= 4 x ( $ 60) = $240
So, the combined loss in next four months = $ 240
Lastly, the profit in the final sixth month of business = $ 125
So, combined PROFIT in the business = Profit in( First + Sixth) Month
= $ 450+ $ 125 = $575
Total loss in the six months = $ 240
Now, total profit for the six month of Jaxon's business
= Total Profit - Total Loss
= $575 - $ 240 = $335
Hence, the total profit for the six month of Jaxon's business is $335.

$60 is a one time fee so only has to be used once in a formula.
Y:25x+60 X= the # of days so just multiply numbers of days by 25 then add the 60.
Rishav takes a loan of rupees 10000 from a bank for a period of 1 year. The rate of interest is 10%
per annum. Find the interest and the amount he has to the pay at the end of a year.
Answer:
The simple interest on the given principal after 1 year = Rs. 1,000
The amount Rishav has to pay after an year = Rs 11,000
Step-by-step explanation:
Here, the Principal amount taken = Rs 10,000
Rate of Interest = 10%
Time Period = 1 year
Now, the SIMPLE INTEREST = [tex]\frac{P \times R \times T}{100}[/tex]
or, [tex]SI = \frac{10,000 \times 10 \times 1}{100} = 1,000[/tex]
So, the simple interest on the given principal after 1 year = Rs. 1,000
Now, Amount = Principal + Simple Interest
or , A = 10,000 + 1,000 = 11, 000
Hence, the amount Rishav has to pay after an year = Rs 11,000
