Which expression is equivalent to 8-(6r+2)
Answer:
-6r+6
Step-by-step explanation:
Simplify
8−(6r+2)
Distribute the Negative Sign:
=8+−1(6r+2)
=8+−1(6r)+(−1)(2)
=8+−6r+−2
Combine Like Terms:
=8+−6r+−2
=(−6r)+(8+−2)
=−6r+6
-6r+6 is equivalent to 8-(6r+2)
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.
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.

What are Independent Variables and Dependent Variables?An independent variable is the variable that the researcher manipulates or changes in an experiment. It is the presumed cause or influence on the dependent variable.
On a graph, an independent variable is always plotted on the x-axis while the dependent variable is plotted on the y-axis. Therefore the statement that is correct is option B.

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
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) :)

Given : A cuboid of length 400 cm, Breadth 220 cm and Height 120 cm is to be made with wood costing Rs.24 per.sq.m.
To find : The cost of construction the box ?
Solution :
A cuboid of length 400 cm, Breadth 220 cm and Height 120 cm.
The total surface area of the cuboid is
TSA=2 (lb+bh+hl)TSA=2(lb+bh+hl)
Substitute the values,
TSA=2 (400\times 220+220\times 120+120\times 400)TSA=2(400×220+220×120+120×400)
TSA=2 (88000+26400+48000)TSA=2(88000+26400+48000)
TSA=2 (162400)TSA=2(162400)
TSA=324800\ cm^2TSA=324800 cm
