Katelyn sells cars at a used car dealer on commission. The car lot pays a 18% commission when the profit on a car is under $400, 22% when the profit is at least $400 and less than $1,000, and 24% when the profit is $1,000 or more. How much will she receive if she sold $800 in profits?
Answer:
She will receive 22% commission
Step-by-step explanation:
18% commission when the profit on a car is under $400
22% when the profit is at least $400 and less than $1,000
24% when the profit is $1,000 or more.
How much will she receive if she sold $800 in profits?
She will receive 22% commission
$800 profits is greater than $400 but less than $1000
Mark invested $500 for 3 years at 6% per annum. The simple interest Mark received was
Answer:
$90
Step-by-step explanation:
We use the simple interest formula,
I = Prt
where
I = interest
P = principal amount = $500
r = interest rate = 6% = 0.06
t = time = 3 years
I = Prt
I = $500 × 0.06 × 3
I = $90

Answer:
Loss=Rs 80
Loss%=4%
Step-by-step explanation:
Cost price of trousers for Ujeli=Rs2000
Marked price for trousers =Rs 2400
Reduction of MP(take it as discounted) =20%
Selling price=MP-20%of MP=2400 - 20/100 * 2400 = 2400 - 480 = Rs 1920
Loss amount =CP - SP = 2000 - 1920 = Rs 80
Loss% =loss amt/CP *100 =80 / 2000 *100 =4%

Answer:
its linear (i know how to draw the graph but i cant show you here, just make umm an x axis and y axis from 1 to 30 ) (also i feel like theres another way to know if its linear but this is how i would do it!)
Step-by-step explanation:
to see if its linear ummm we first have to find the slope, the equation for the slope is
y2 - y1 / x2 - x1
lets use the points (2, 8) and (3, 12)
12 - 8/ 3 -2
4 / 1
4
y = 4x + b
now to find the y-intercept lets input a point we did not use yet
(5, 20)
20 = 4(5) + b
20 = 20 + b
b = 0
y = 4x
now we check if its linear with the points (6, 24) and (3.5, 14) sooo
24 = 4(6) ?
24 = 24
14 = 4(3.5) ?
14 = 14
so yes it is a linear graph
The height h (in feet) of an object dropped from a window after x seconds can be modeled by h(x)=−16x2+64 . The object is dropped a second time so that it hits the ground 1.5 seconds sooner. Write a function g that models the path of the object the second time it is dropped.
Answer:
g(x) = - 16x² + 4
Step-by-step explanation:
Given the model:
First drop:
h(x) = - 16x² + 64
Second drop hits the ground 1.5 seconds sooner
Function g(x) to model the second drop:
-16t² + V0t + h0
h(x) = - 16x² + 64
0 = - 16x² + 64
16x² = 64
x² = 64/16
x = 2
1.5 seconds sooner :
X = 2 - 1. 5
x = 0.5
0 = - 16(0.5)² + 0 + h0
0 = - 4 + h0
h0 = 4
Hence,
g(x) = - 16x² + 4

Suppose the cost of mailing a letter is $0.23 per ounce plus $0.14. The equation
gives the total cost c of mailing a letter is c = 0.23w + 0.14, where w is the weig
ounces. What is the cost of mailing a 6-ounce letter?
Answer:
$2.22
Step-by-step explanation:
First, we know that the cost of one mailing letter is $0.23 per once, plus $0.14.
Our formula is: c = 0.23w + 0.14
Let's rewrite our variables to the way it's suppsed to be.
C = cost
W = weight ounces.
Now, we have to add 0.23 plus 0.14 to get our cost.
That equals 0.37.
Now that we know that our cost for one letter is 0.37, we have to multiply
it by 6, because we are trying to figure out the cost of mailing a 6 ounce letter.
0.37 × 6 = 2.22
In conclusion, the cost of mailing a 6 ounce letter is $2.22

The employees of a hardware store ordered lunch from a local delicatessen. The lunch consisted of 4 turkey sandwiches and 7 orders of french fries, for a total cost of $38.30. The next day, the employees ordered 5 turkey sandwiches and 5 orders of french fries totaling $40.75. What does the delicatessen charge for a turkey sandwich? What is the charge for an order of french fries?
Answer:
Charges of Turkey is $6.25
Charges of French Fries is $1.90
Step-by-step explanation:
Given
Represent Turkeys with T and French Fries with F;
[tex]4T + 7F = 38.3[/tex]
[tex]5T + 5F = 40.75[/tex]
Required
Determine the values of T and F
[tex]5T + 5F = 40.75[/tex]
Divide through by 5
[tex]T + F = 8.15[/tex]
Make F the subject
[tex]F = 8.15 - T[/tex]
Substitute 8.15 - T for F in the first equation
[tex]4T + 7F = 38.3[/tex]
[tex]4T + 7(8.15 - T) = 38.30[/tex]
[tex]4T + 57.05 - 7T = 38.30[/tex]
Collect Like Terms
[tex]4T - 7T = 38.30 - 57.05[/tex]
[tex]-3T = -18.75[/tex]
Solve for T
[tex]T = -18.75/-3[/tex]
[tex]T = 6.25[/tex]
Recall that:
[tex]F = 8.15 - T[/tex]
[tex]F = 8.15 - 6.25[/tex]
[tex]F = 1.90[/tex]
What is the length of diagonal RQ?
9.3 in
22 in
18.6 in
11 in
Assuming the entire quadrilateral is a parallelogram, we can say that using the property of diagonals;
The diagonals of a parallelogram bisect each other, meaning that RQ is divided into two equal parts.
If half of RQ is 9.3 then,
RQ=2×9.3=18.6 in
That's your answer RQ=18.6 in
Answer:
the answer is C.18.6

For each expression, select all equivalent expressions from the list.
Answer:
(a) 7x +6x, (d) 13x(b) 3 +27y, (c) 3·1 +3·9yStep-by-step explanation:
You want to identify the expressions equivalent to 11x -4x +6x and 3(1 +9y).
SimplifyWe can identify the equivalent expressions by putting them all in their simplest form. This means using the distributive property to eliminate parentheses, and combining like terms.
(a) 11x -4x +6xThe simplified version of the given expression is ...
(11 -4 +6)x = 13x
The other expressions simplify to ...
7x +6x = (7+6)x = 13x . . . equivalent
7x -6x = (7 -6)x = 1x = x . . . not equivalent
13 +x (already simplest) . . . not equivalent
13x (already simplest) . . . equivalent
(b) 3(1 +9y)
The simplified form of the given expression is ...
3·1 +3·9y = 3 + 27y
The other expressions simplify to ...
3 +1·3 +9y = 6 +9y . . . not equivalent
3 +27y . . . equivalent
3·1 +3·9y = 3 + 27y . . . equivalent
3 +9y (already simplest) . . . not equivalent

O y=-6x - 15
O y = -6x - 20
y=-6x + 15
Oy=-6x + 20
What’s the answer
Answer:
y= -6x - 15
Step-by-step explanation:
First you need to plug in the x and y coordinates into the equation y = -6x and you should get (-3) = -6(-2). Then you do -6 x -2 which is 12 then subtract 12 from -3 and get -15.

Salary after 10 years at the company will be 3s+2000.
It is given that original salary =s
What is the multiplication of a variable x to constant p?The multiplication of a variable x to constant p is px.
Salary after 10 years as per promise = thrice of original salary +$2000
Salary after 10 years = 3*s + 2000
Salary after 10 years = 3s+2000
Therefore, salary after 10 years at the company will be 3s+2000

Find the surface area of a square pyramid with side length 3 km and slant height 4 km.
Answer:
The pyramid consists of 4 triangles having bases of 3 km and height of 4 km (measured along the face)
A = 4 * 3 / 2 * 4 = 24 km^2
Each triangle has an area of 1/2 * bottom length * height
3 cannot refer to the length of one of the isosceles triangles because a slant height of 4 km is given and is less than one such side
The surface area of the square pyramid is 24 km².
What is the surface area of a square pyramid with a slant height?The surface area of a square pyramid with a slant height can be determined by the product of the base perimeter with the slant height divided by two.
Mathematically, it can be expressed as:
Surface Area S.A = P × l/2
where;
Side length (a) = 3Base perimeter (P) = 4a = 4(3) = 12kmSlant length (l) = 4 kmSurface Area (S.A) = 12 × (4/2)

Two water balloons were launched into the air at different moments and collided. The water balloons were modeled by the quadratic functions: y = −3x2 + 24x + 3 and y = −4x2 + 25x + 15, where y represents the height in meters and x represents the time in seconds after the launch. What is the time, in seconds, that the balloons collided at the highest point?
3.25 seconds
3.50 seconds
3.75 seconds
4.00 seconds
Answer:
Step-by-step explanation:
When the balloons collide, they have the same x and y:
-3x^2 + 24x + 3 = y = -4x^2 + 25x + 15
Rearranging like terms together:
(4x^2 - 3x^2) + (24x - 25x) + (3 - 15) = 0
x^2 - x - 12 = 0
(x - 4)(x +3) = 0
x = 4 or -3
As x represents time, it cannot be negative.
The time when the balloons collide is at 4.00 seconds.
The collision means that y is equal
y=-3x²+24x+3y=-4x²+25x+15So
-3x²+24x+3=-4x²+25x+15-3x²+4x²+24x-25x=15-3x²-x=12x²-x-12=0(x-4)(x+3)=0x=4,-3As it's time so must be positive
