Contestants in a dance-a-thon rest for the same amount of time every hour. A couple rests for 28 minutes in 4 hours. How long did they rest in 7 hours?
Contestants in a dance-a-thon rest for the same amount of time every hour. A couple rests for 24 minutes in 3 hours. How long did they rest in 5 hours?
Answer: 40 minutes
Step-by-step explanation: The first thing you want to do is divide 24 by 3 to find how much each dancer rested per hour. In other words, find the unit rate. 24 divided by 3 is 8. Next, take the 8 and multiply it by 5, since we are trying to find how much each dancer rested in 5 hours. 8 x 5 = 40. So each contestant rested for 40 minutes.
Here is a triangular prism
All measurements are in centimeters
Calculate the volume and surface area of the prism.
Answer:
Volume = 42 cm^3, Surface Area = 96 cm^2
Step-by-step explanation:
Volume = Area * Height
S = semi-perimeter or half of the perimeter
Area of the triangle using heron's formula = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
S = (3 + 4 + 5)/2 = 6 cm
Area of triangle = [tex]\sqrt{6(6-3)(6-4)(6-5)}[/tex]
= [tex]\sqrt{6 * 3 * 2 * 1}[/tex]
= [tex]\sqrt{36}[/tex]
= 6 cm^2
Volume = 6 * 7
= 42 cm^3
Surface Area = Area of bases * Area of Lateral faces
Area of lateral faces = 7 * 3 + 7 * 4 + 7 * 5 = 84 cm^2
Area of bases = 6 cm^2 * 2 = 12 cm^2
Surface area = 12 cm^2 + 84 cm^2 = 96 cm^2

5x + 2(x + 7) = 14x – 7 The first one to answer gets brainalist. Social Test.
Answer:
The answer is True.
Step-by-step explanation:
Step 1: Evaluate the left side of the equal sign:
5x + 2(x + 7) = 14
Step 2: Evaluate the right side of the equal sign:
14x–7 = 14
Step 3: Determine if the true-false equation is true or false:
Since 14 = 14, then 5x + 2(x + 7) = 14x–7 is True
3. The question is in the picture.
Answer:
No
Step-by-step explanation:
The reason for this is that the line is not increasing by 1.5. If we take the 2 y values which are 20 and 10. 20-10 is 10 and if we take the 2 x values and subtract them, we would get 30-15 which is 15. Now divide the y value and the x value (10/15) and we would get 0.66666.... Which is not 1.5. This was probably done because he mixed up the x values and y values which would be 15/10 and a common mistake when reading a coordinate plane. This does show a proportional relationship because the line is constant and therefore proportional. Hope this helps!

Brenda is training for the New York City Triathlon. She is nervous about swimming 1.5 kilometers in the Hudson River. So, she wants to make sure that she can swim that far in a swimming pool. So far, she has swum 20 laps. If each lap is 25 meters, how many more laps does she have to swim?
Answer:
she has 40 more laps to go
Step-by-step explanation:
1,500 meters are in 1.5 kilometers. So if you use this equation you´ll find the answer to how many miles she will need in total. 1,500/25=60 then subtract 20.
The Elver Elementary School students started a new tradition last year of planting trees on Earth Day. They planted 4 trees last year. Let n be the number of trees the students plant this year, and let t be the total number of trees planted.
The equation t=n+4 represents this situation. Graph the equation. HELP NEED ANSWER FAST!!
Answer:
The graph below should represent t = n + 4. The slope should be 1 and the y-intercept should be (0, 4).
Answer:
graph below should represent t = n + 4. The slope should be 1 and the y-intercept should be (0, 4).
Step-by-step explanation:
Three specialists can complete in 1 hour the job their 5 assistants usually do in 1 hour. Suppose eight specialists can complete a certain job 9 hours. How many assistants can complete the same job in 10 hours?
Answer:
12 assistants
Step-by-step explanation:
If 5 assistants can do in 1 hour what 3 specialists can do, you want to know the number of assistants needed to do in 10 hours what 8 specialists can do in 9 hours.
EffortThe 1-hour job tells us that how to relate the effort of assistants to that of specialists:
5 assistant·hours = 3 specialist·hours
The longer job takes 8 specialists 9 hours, so is a job requiring an effort of ...
(8 specialists)·(9 hours) = 72 specialist·hours
In terms of assistant·hours, that is ...
72 specialist·hours = 24(3 specialist·hours) = 24(5 assistant·hours)
= 120 assistant·hours = (12 assistants)(10 hours)
It takes 12 assistants to complete the same job in 10 hours.

What is square root of 48 in simplified form?
4 square root of 3
square root of 48 can't be simplified.
2 square root of 12
24
Answer:
4 square root 3 or 6.298
Step-by-step explanation:
Hope this helps! :)
Answer: [tex]4\sqrt{3}[/tex] (choice A)
========================================
Work Shown:
[tex]\sqrt{48} = \sqrt{16*3}\\\\\sqrt{48} = \sqrt{16}*\sqrt{3}\\\\\sqrt{48} = 4\sqrt{3}[/tex]
The idea is to factor 48 such that one of the factors is the largest perfect square possible. So that's why we go with 48 = 16*3. Then we use the rule [tex]\sqrt{x*y} = \sqrt{x}*\sqrt{y}[/tex] to break up the root.
The sun produces 3.9 ⋅ 1033 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in 1.55 ⋅ 107 seconds?

In a blueprint, each square has a side length of 1/4 inch.
a. Ceramic tile costs $5 per sqare foot. How much would it cost to tile the bathroom?
b. Carpet costs $18 per square yard. How much would it cost to carpet the bedroom and the living room?
Answer:
a. it would cost 30 dollars
b. it would cost 360 dollars
The cost to carpet the bedroom and the living room is $12.75.
Given that, in a blueprint, each square has a side length of 1/4 inch.
What is metric conversion?Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
a) Now, the dimensions of bathroom are length=3/4 inches and width=1/4 inches
Area of a bathroom =3/4 ×1/2
= 3/8 square inches
Cost of 1 square inch = 5/12 per square inch
So, cost to tile the bathroom = 3/8 ×5/12
= 15/96
= $0.15625
b) The dimensions of living room are length=7/4 inches and width=4/4 inches
Area of a living room = 7/4 ×4/4
= 28/16
Cost of 1 square inch = 18/3 per square inch
= $6 per square inch
Cost of carpet for the bathroom = 3/8 ×6
= $2.25
Cost of carpet for the living room = 28/16 ×6
= $10.5
Total =2.25+10.5
= $12.75
Therefore, the cost to carpet the bedroom and the living room is $12.75.

What is the rate of change of the linear relationship modeled in the table?
X Y

3 5
5 8
7 11
A. -3/2
B. 2/3
C. 1
D. 3/2
Answer:
D: 3/2
Step-by-step explanation:
This is because on the Y side: It is gaining numbers by 3. On the x side it is gaining by 2. So it is 2/3. But you have to do Delta. Which now is 3/2 instead of 2/3. So to answer your question: The correct answer is hence D: 3/2.
