Answer:
option A sounds like a better deal if that's what your asking.
A fast-food restaurant has a cost production of C(x) = 7x + 117 and a revenue
function of R(x) = 28x, where I represents the number of milkshakes they
make. When does the company start to turn a profit?
Answer:
6
Step-by-step explanation:
Profit is revenue minus cost.
P(x) = R(x) − C(x)
P(x) = 28x − (7x + 117)
P(x) = 21x − 117
When the profit is 0, the value of x is:
0 = 21x − 117
21x = 117
x = 5.6
Rounding up to the nearest integer, the company starts to turn a profit at 6 milkshakes.
2. At Lucky's Go-Cart Track it costs $5 to rent a go-cart. They then charge a fee of $4 per hour. At
Speedy's Race Track it costs $10 to rent a go-cart plus $2 per hour. Which equation would help you to
solve how many hours you would need to rent a go-cart at Speedy's Race Track for it to be cheaper
than Lucky's Go-Cart Track?
A) 5+4h-10-2h
B) 5h+4=10h+2
C) 10+2h=5+4h
D) 5 2h=10+4h
Answer:
C) 10+2h=5+4h
Step-by-step explanation:
I think it's C because it says the equation correctly. (Remember we don't know how many hours a persons going to be there so that would be h.)

Triangles are not similar
[tex]\frac{11}{33}[/tex] ≠ [tex]\frac{8}{20}[/tex] = [tex]\frac{6}{15}[/tex]
[tex]\frac{2}{5}[/tex] = [tex]\frac{2}{5}[/tex] ≠ [tex]\frac{1}{3}[/tex]
Angle A and Angle B are supplementary, mZA = (6x + 72) and mZB = (2x + 28)". Find x, the
mZA and the mZB.
Answer:
x = 10
m<A = 132 degrees
m<B = 48 degrees
Step-by-step explanation:
Supplementary = angles that make up 180 degrees
We know <A and <B are supplemntary, so 2x+28+6x+72 = 180.
8x + 100 = 180
8x = 80
x = 10
I input 10 into the equations to solve for the measures of the angles
Which operation would you use to solve for x in the equation 3x = 15?
Answer:
Division
Step-by-step explanation:
3x = 3 times x so, you must do the opposite of multiplication to get rid of the 3, which is division.
The solution of the equation with a single variable 3x = 15 will be 5.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The equation is given below.
3x = 15
Divide the equation by 3 into both sides, then we have
3x / 3 = 15 / 3
x = 5
The solution of the equation with a single variable 3x = 15 will be 5.
More about the solution of the equation link is given below.

Kelsey and her 4 sisters spent an equal amount of time cleaning their home. their parents added their times. they found that each of the five girls spent three hours cleaning. let c be the total number of hours the girls spent cleaning right and solve a division equation to find the total number of hours the girls spent cleaning
Answer:
15 hours
Step-by-step explanation:
Kelsey + 4 sisters = 5 girls
Each of the 5 girls spent three hours cleaning
Usually, I would do 5 x 3 = c, but since we need to use a division equation, we should use c / 5 = 3 OR c / 3 = 5.
c/5 = 3
3 x 5 = 15
Check: 15/ 5 = 3
7. Which of the following illustrates the commutative property of multiplication?
(1) 5(2x) =(5-2)x
(2) 4(2x+5) = 4 - 2x+4-5
(3) x2 +5=5+x2
(4) 2x -3x = 2-3-X-X

The employees at a bank ordered 2 turkey sandwiches and 4 salads from a local deli. The total cost for the order was $23. If a salad costs $1 less than a turkey sandwich, what is the cost of a turkey sandwich and the cost of a salad?
Answer:
Cost of turkey sandwich is $4.50 and cost of salad is $3.50
Step-by-step explanation:
Let cost of 1 turkey sandwich be $t and cost of 1 salad be $s.
2t + 4s = 23 --(1)
s + 1 = t
s = t - 1 --(2)
Sub (2) into (1):
2t + 4(t - 1) = 23
6t - 4 = 23
6t = 27
t = 4.5
sub t = 4.5 into (2):
s = 4.5 - 1
s = 3.5
therefore, cost of turkey sandwich is $4.50 and cost of salad is $3.50

The speed of the current in a creek is 2 mph. A person can kayak 9 mi upstream in the same time that it takes him to kayak 13 mi downstream. What is the speed of the
person's kayak in still water?
Let s be the speed of the person's kayak in still water.
Given, speed of current = 2 mph
Upstream distance = 9 miles
Speed of the person upstream = s-2
Time traveled upstream = 9/s-2
Downstream distance = 13 miles
Speed of the person downstream = s+2
Time traveled downstream = 13/s+2
Given,
9/s-2 = 13/s+2
Cross-multiplying,
9*(s+2) = 13*(s-2)
9s + 18 = 13s - 26
Grouping like terms together,
13s-9s = 26+18
4s = 44
s = 11 mph
Speed of person's kayak in still water = 11 mph

If a cake recipe requires 3:2 by weight ratio of sugar and flour, how much sugar do you need to make a 10 pound cake?
Answer:
6 pounds of sugarStep-by-step explanation:
Given the ratio of sugar and flour by weight expressed by the ratio 3:2
Total ratio = 3+2 = 5
Ratio of sugar = 3
If we are to make 10pounds cake, the amount of sugar needed will be expressed as;
Amount of sugar = Ratio of sugar/Total sugar *weight of cake
Amount of sugar = 3/5 * 10
Amount of sugar = 3 * 2
Amount of sugar = 6pounds
Hence 6pounds of sugar is needed to make the cake

Answer:

Step-by-step explanation:
5.42 - 4.987
Subtract each column of digits starting from right to left.
5.420
- 4.987
If the digit being subtracted is larger than the digit above it then borrow a digit from the next left column.
5.420
- 4.987
Borrow 1 from 5:
4.(10+4)20
- 4.987
4.(14)20
- 4.987
Borrow 1 from 14:
4.(13)(10+2)0
- 4.987
4.(13)(12)0
- 4.987
Borrow 1 from 12:
4.(13)(11)(10+0)
- 4.987
4.(13)(11)(10)
- 4.987
Subtract the second digit from the first:
(10 - 7 = 3):
4.(13)(11)(10)
- 4.987
= 3
(11 - 8 = 3):
4.(13)(11)
- 4.987
= 33
(13 - 9 = 4):
4.(13)
- 4.987
= 433
4.(13)
- 4.987
= .433
(4 - 4 = 0):
4.(13)
- 4.987
= 0.433
