Jill has a coupon for 15% off at her favorite restaurant, Downtown Noodles. You can use a function to estimate how much Jill will pay if the bill is x dollars
Answers
Answer:
Step-by-step explanation:
Let function p(x) be the price that is reduced by 15% if the bill is x dollars.
Since the price is not payed in full 100% is reduced by 15% we only pay
100 - 15 = 85 % of the original price.
p(x) = x· (100% - 15 %) = x· 85% = 0.85 x
The function used to calculate any bill that is reduced by 15% is:
p(x) = 0.85x
x - is the bill before being reduced by the coupon

Janis was offered two different jobs when she graduated from college. she made the graph and table to show how much she would earn over time at each job. earnings over time for job 1 earnings over time for job 2 a graph entitled earnings over time for job 1 has year on the x-axis and earnings in dollars on the y-axis. a line with positive slope goes through (0, 40,000) and (10, 60,000). y = 2,000 x 40,000. a 2-column table entitled earnings over time for job 2 has 7 rows. the first column is labeled year with entries 10, 12, 14, 16, 18, 20, 22. the second column is labeled earnings in dollars with entries 55,000, 60,000, 65,000, 70,000, 75,000, 80,000, 85,000. when will janis’s salary be the same for job 1 and job 2, and how much will she be earning at that point? the salaries will be the same in year 20, and she will be earning $80,000. the salaries will be the same in year 16, and she will be earning $70,000. the salaries will be the same in year 12, and she will be earning $60,000. the salaries will be the same in year 10, and she will be earning $55,000.
Answers
The salaries will be the same in year 20 and she will be earning $80,000. So, the first option is correct.
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form.
We will first create an equation to represent the data.
To find the slope we use the formula
m = (y₂-y₁)/(x₂-x₁)
= (60,000-55,000) / (12-10)
= 5,000/2 = 2500
Writing this in point-slope form, we have
y-y₁ = m(x-x₁)
y-55,000 = 2500(x-10)
Converting to slope-intercept form,
y-55,000 = 2500 × x - 2500 × 10
y - 55,000 = 2500x - 25,000
y = 2500x + 30,000
Now we set this equal to the equation from the graph:
2500x + 30,000 = 2000x + 40,000
Subtract 2000x from both sides:
2500x + 30,000 - 2000x = 2000x + 40,000 - 2000x
500x + 30,000 = 40,000
500x = 40,000 - 30,000
500x = 10,000
x = 10,000/500
x = 20
The salaries will be the same in year 20.
y= 2000(20) + 40,000
y= 40,000 + 40,000
= 80,000
The salary in year 20 will be $80,000.

Area of semi circle = π r²/2
= π 20 × 20 / 2
= 200 π
= 628 cm² (approx)
Answer:
To the nearest whole number : 628
Step-by-step explanation:
The formula for the area of a circle is :
To work out the area you would first need to work out the radius. You can do this by dividing the diameter of 40 cm by 2, this gives you 20 cm. This is because the radius is half of the diameter.
Now that we have worked out the radius, the next step would be to work out the area. You can do this by multiplying pi by the radius of 20 squared, this gives you 1256.64.
The final step is to work out the area of this semi-circle. You can do this by dividing the area of 1256.64 by 2, this gives you 628.32 . This is because a semi-circle is half of a circle.
1) Divide 40 by 2.
2) Multiply pi by 20 squared.
3) Divide 1256.64 by 2.

12 oz for $2.29
15 oz for $2.75
20 oz for $3.89
Answers
Answer:
D.
Step-by-step explanation:
We know that to find unit price, we divide the unit in the numerator by the quantity in the denominator.
For the first option, we must put $1.49 as the numerator and 8 as the denominator. It will then look like this:
[tex]\frac{1.49 / 8 }{8 / 8\\}[/tex] Then we must divide 1.49 by 8. This will get us $0.18625.For our second option, we must put $2.29 as the numerator, and 12 as the denominator. It will look like this:
[tex]\frac{2.29 / 12 }{12 / 12\\}[/tex] Then we must divide 2.29 by 12. This will get us $0.19083 (rounded)For our third option, we must put $2.75 as the numerator, and 15 as the denominator. It will look like this:
[tex]\frac{2.75 / 15 }{15 / 15}[/tex]Then we must divide 2.75 by 15. This will get us $[tex]0.18333[/tex] (rounded)For our final option, we must put $3.89 as the numerator, and 20 as the denominator. It will look like this:
[tex]\frac{3.89 / 20 }{3.89 / 20}[/tex]Then we must divide 3.89 by 20. This will get us $0.1945 (rounded)Therefore, the last option is the best buy because $0.18625 > $0.18333.

Step-by-step explanation:
The values on the given table are presented as follows;
Value of spin: 0,1,2,5,10
Probability: 0.4,0.2,0.2,0.1,0.1
To find the median, we calculate the cumulative probabilities to find the value of the spin art which the cumulative probability is 0.5 as follows;
Cumulative probability, starting from the left, is therefore;
Probability for spin of 0, 0.4 + Probability for spin of 1, 0.2 = 0.6
Therefore, given that the probability of 0.5 occurs within the Value of Spin 1, the median of the probability distribution is 1
The solution is : The median of the distribution is (first option) 1
What is median?In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

The consecutive angles of a parallelogram are________?
Answers
Answer:
supplementary
Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Each diagonal of a parallelogram separates it into two congruent triangles.
Answer:
Supplementary
Step-by-step explanation:
The consecutive angles of a parallelogram are supplementary.
Two angles that add up to 180° are called supplementary angles.
This can be proven by creating a parallelogram and extending all segments to create two parallel lines transversing another set of two parallel lines.
I drew a diagram of this shape and considering that all the opposite lines are parallel, the central shape is a parallelogram.
Looking at the diagram attached, we know that the angle of a straight line is 180° (represented by the yellow of Angle 1 and the pink angle next to it) All angles of the same color are congruent by angle theorems consisting of corresponding and vertical angles.
If pink is x, and yellow is y, then we can say that x + y = 180°
So, therefore we can say that the consecutive angles of the parallelogram (Angle 1 and Angle 2) sum up to 180°, because they are made up of one pink angle and one yellow angle ( x and y )
