Hank is throwing a surprise party. The party costs $20 per person. Create an equation and graph to represent the relationship between the cost of the party and the number of friends attending.
The dependent variable is ____.
A. Number of friends (f)
B. Cost of party (c)
PLZ HELP ME
Answers
Answer:
number of friends would be independent making the dependent the cost of the party
Step-by-step explanation:
Hey love! <3
Answer:
Equation: c = 20f
The dependent variable is B. Cost of party (c)
Step-by-step explanation:
First let's define our variables.
C = Cost of party
F = Number of friends
If every person coming costs 20 dollars then the amount of friends times the money amount will represent the cost of the party.
So if c equals the cost of the party, then 20 times f is that total cost.
Thus, c = 20f, additionally defining B as the dependant variable since the cost is depending on how many people show up.
As for your graph, just make a simple line graph with the cost on the y axis and the number of friends on the x axis (increasing by twenty with each friend) :)

What is a number line?A number line refers to a straight line in mathematics that has numbers arranged at regular intervals or portions along its width. A number line is often shown horizontally and can be postponed in any direction.
When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.
The expression is given below.
⇒ 1/5 + (-4/5)
⇒ 1/5 - 4/5
⇒ (1 - 4) / 5
⇒ - 3/5
⇒ - 0.60
The location of the point 1/5 + (-4/5) on the number line will be negative 0.60.

The plan of a patio deck is shown at the right. The scale is 2 inches: 6 feet. What are the length and width of the deck
Answers
Answer:
5in.=15ft. 2in.=6ft.
Step-by-step explanation:
What you have to do is translate 6ft. into inches which is 72in. Then you divide that by 2in. From that you get 36in. You then take that 36in. and multiply it by the 5in for the length. from that you get 180in. You divide the 180in. by 12 to turn your inches into feet and you end up with 15ft.

1. Design a strategy in which the Pythagorean theorem is used to calculate the straight line distance between points G and I on a coordinate plane. Use complete sentences to describe the strategy.
2. Use the Pythagorean theorem to determine the distance between the two points on the coordinate plane. In your final answer, include all of your calculations.
3. Use the distance formula and the coordinates of points G and I to prove that the Pythagorean theorem is an alternative method for calculating the distance between points on a coordinate plane. In your final answer, include all of your calculations.

Andre is making paper cranes decorate for a party. He plans to make one large paper crane for a centerpiece and several smaller paper cranes to put around the table. It takes Andre 10 minutes to make the centerpiece and 3 minutes to make each small crane. He will only have 30 minutes to make the paper cranes once he gets home.
Andre wrote the inequality 3x + 10 ≤ 30 to plan his time. Describe what x, 3x, 10, and 30 represent in this inequality.
Answers
Answer:
Andre can make 6 small paper cranes in 30 minutes.
Step-by-step explanation:
Given data-
Time taken by Andre to build small cranes- 3minutes
Time taken to build large crane- 10 minutes
Total time allotted to him= 30 min
His preferences- Building one large crane and several small cranes.
The Inequality equation is 3c + 10 ≤ 30
Since his preference is to build atleast one large crane which takes 10 minutes, he is left with 30-10 = 20 minutes to build other small cranes.
For one crane he needs, 3 minutes
Hence, he can build 6 cranes in 18 minutes. Following this, he is left with 20-18= 2 minutes. Since he needs at least 3 min to build a small crane, he cannot build a small crane in the remaining 2 min.
he builds 6 small cranes in 30 minutes
Alternatively,
3c + 10 ≤ 30
Subtracting 10 from both sides
3c ≤ 20
The maximum value of c for which this equation remains valid is 6.
Thus, he builds a total of 6 cranes (small) in 30 minutes.
I hope this helps.

Answers
Answer:
No
Step-by-step explanation:
If you know fractions, the dividend is the numerator, for example 4 would be the numerator for 4 divided by 3, and the divisor would be the denominator, which for 4 divded by 3 would be 3. Therefore, 4 divided by 3 is equal to 4/3, not 3/4.
Jamal is wrong the value of the fraction 3/4 is not equal to 4÷3.
