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.
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?
Answers
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.

Answer:
D
Step-by-step explanation:
Area of figure
= area of triangle +area of rectangle
Area of triangle
= ½ ×base ×height
= ½(6)(3.5)
= 10.5 ft²
Area of rectangle
= length ×breadth
= 6(4.6)
= 27.6 ft²
Area of figure
= 10.5 +27.6
= 38.1 ft²
Thus, option D is correct.
38.1 square feet
===============================================
Work Shown:
area of triangle = base*height/2 = 6*3.5/2 = 10.5
area of rectangle = base*height = 6*4.6 = 27.6
total area = triangle + rectangle = 10.5+27.6 = 38.1 square feet

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?
Answers
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.

7y + 7 = 56.
42 - 6y = 6,
(y + 1){2} = 9,
1 + 72/y = 10,
Answers
Answer:
1. y = 7
2. y = 6
3. y = 7/2
4. y = 8
Step-by-step explanation:
I searched it up and found the answer.
Let's solve each equation one by one :
7y + 7 = 56➝ 7y + 7 = 56
➝ 7y = 56 - 7
➝ 7y = 49
➝ y = 49 / 7
➝ y = 7
42 - 6y = 6➝ 42 - 6y = 6
➝ - 6y = 6 - 42
➝ - 6y = - 36
➝ y = -36 / - 6
➝ y = 6
( y + 1 )² = 9➝ ( y + 1 )² = 9
➝ y + 1 = √ 9
➝ y + 1 = 3
➝ y = 3 - 1
➝ y = 2
1 + 72 / y = 10➝ 1 + 72 / y = 10
➝ 72 / y = 10 - 1
➝ 72 / y = 9
➝ 72 = 9y
➝ 9y = 72
➝ y = 72 / 9
➝ y = 8

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?
Answers
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.

3. The question is in the picture.
Answers
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!

Step-by-step explanation:
Explanation:
start with 1 as the total number of school lunches.
to find the fraction of dumplings made, subtract the two other fractions from 1, so:
1 - (1/4 + 3/5) = # of dumplings
first make a common denominator for 1/4 and 3/5:
= 1 - (5/20 + 12/20)
= 1 - (17/20)
then, rewrite 1 as a fraction with 20 as the denominator:
= 20/20 - 17/20
= 3/20
and you can't simply this fraction further therefore the fraction of school lunches that are dumplings is 3/20
