Lukas is running a lemonade stand on a hot summer day. He spent $14 for the materials and earns $1.50 for each cup of lemonade sold. What is an equation that relates the number of cups of lemonade sold, c and the profit earned, P, and explain whether Lukas selling 19.5 cups is a viable solution.
Answers
The equation would be 1.50x - 14 = P
If lucas sells 19. cups then that means he will earn a total of 29.25$ but since he spent 14$ for the materials itself that concludes to the total being 15.25.This would be a viable solution because he is earning more money then he is loosing.

A fundraiser is being held to support a local nonprofit organization. Admission costs $10, and each raffle ticket costs $3. There are no other possible costs. If an event-goer pays the admission fee and buys x number of tickets, what type of function should be used to model the total amount spent by the event-goer at the event?
Answers
Answer:
y= 10+ 3x
10 is the admission fee
3x is the cost for each ticket
y is the total
The function for the total cost (y) spent by the event-goer at the event is
y = 3x+10
What is a function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
Given that, Admission costs $10, and each raffle ticket costs $3. There are no other possible costs.
Let the total cost be y,
Therefore, establishing the function, for x number of tickets.
y = 3x+10
Hence, the required function is y = 3x+10

Find the sale price of the item. Round to two decimal places when
necessary. *
Original Price: $40.00; Markdown: 15%
$46
$34
$42
$32
Answers
First, determine what 15% of $40 is.
Convert 15% to a decimal: 0.15
Then multiply this decimal by $40: 0.15 x 40 = 6
So the discount is $6.
We subtract the discount from original price to get sale price.
40-6= 34
So the item will cost $34.

In an electric circuit, the current varies inversely as the resistance. The current is 40 amps when the resistance is 12 ohms. Find the current when the resistance is 20 ohms.
Answers
Answer:
24 amps
Step-by-step explanation:
Current = k /resistance
k = current × resistance
= 40 × 12

If the resistance is 20 ohms then the current can be calculated as follows
Current = 480/20
= 24 amps

Fernando is trying to incorporate more exercise into his busy schedule. He has several short exercise routines he can complete at home. Last week, he worked out for a total of 88 minutes by doing 2 arm routines and 3 abdominal routines. This week, he has completed 4 arm routines and 1 abdominal routine and spent a total of 66 minutes exercising. How long does each routine last?
Answers
Answer: Arm routine = 11 minutes
Abdominal routine = 22 minutes
Step-by-step explanation:
Let the minutes used for an arm routine be represented by x.
Let the minutes used for an abdominal routine be represented by y.
Last week, he worked out for a total of 88 minutes by doing 2 arm routines and 3 abdominal routines. This can be expressed as:
2x + 3y = 88
This week, he has completed 4 arm routines and 1 abdominal routine and spent a total of 66 minutes exercising. This can be expressed as:
4x + y = 66
2x + 3y = 88 ...... i
4x + y = 66 ...... ii
Multiply equation I by 4
Multiply equation ii by 2
8x + 12y = 352 ...... iii
8x + 2y = 132 ...... iv
Subtract iv from iii
10y = 220
y = 220 / 10
y = 22
An abdominal routine last for 22 minutes
From equation I
2x + 3y = 88
2x + 3(22) = 88
2x + 66 = 88
2x = 88 - 66
2x = 22
x = 22/2
x = 11 minutes
An arm routine last for 11 minutes

Answers
Answer:
SinZ=24/40 = 12/20 = 3/5
C)
The value of the trigonometric ratio Sin Z for the given triangle XYZ will be [tex]\frac{3}{5}[/tex], i.e. option C.
What are trigonometric ratios?The trigonometric ratios are the ratios of sides of two sides of right angled triangle used in trigonometry. Trigonometric ratios are used to find the value of the acute angles in a right triangle when the sides of the triangle are given.
We have,
A right-angled triangle XYZ with the given values,
Angle Y = 90°
And,
YZ = 32, XY = 24 and XZ = 40,
Now,
Using the trigonometric ratios,
i.e.
[tex]Sin Z=\frac{Perpendicular}{Hypotenuse}[/tex]
i.e.
[tex]Sin Z=\frac{XY}{XZ}[/tex]
So,
[tex]Sin Z=\frac{24}{40}[/tex]
On simplifying,
We get,
[tex]Sin Z=\frac{3}{5}[/tex]
So,
The option C is the correct answer for the given triangle find out using trigonometric ratio,
Hence, we can say that the value of the trigonometric ratio Sin Z for the given triangle XYZ will be [tex]\frac{3}{5}[/tex], i.e. option C.

Your school is installing new turf on the football field. A coordinate plane has been superimposed on a diagram of the football field where 1 unit = 20 feet. A) what is the length of the field. B) what is the perimeter of the field. C) Turf costs $2.69 per square foot. Your school has a $150,000 budget. Does the school have enough money to purchase new turf for the entire field? Please show the steps.
Answers
Answer:
Step-by-step explanation:
1) length of the field = 18 unit= 18*20=360 ft
2) circumference = 2(l+w)
2*(18*20+8*20)=1040
3) Area of the field = 18*8 units = 18*20*8*20ft^2 = 57600ft^2
Cost for the entire area= 57600*2.69= 170,000$
No it doesn't
A) The length of the field is 360 feet
B) The Perimeter of field is 1040 feet
C) The school does not have enough money to purchase new turf for the entire field.
what is Area of rectangle?The Area of rectangle is the product of the length to its width.
Area of rectangle= length x width
Given:
1 block= 20 feet
A) length= 18 blocks
= 18 x 20
= 360 feet
width= 8 blocks
= 8 x 20
= 160 feet
B) Perimeter of field
= 2( l+w)
=2( 360 + 160)
= 2 x 520
= 1040 feet
C) Area of field
= l x w
=360 x 160
= 57600 feet²
If cost of 1 square feet is $2.96
and, the cost of 57600 feet²
= 2.96 x 57600
= $170,496
No, the school does not have enough money to purchase new turf for the entire field.
