Answer:
1/50
Step-by-step explanation:
solve each equation
Hint: y < 10
7y + 7 = 56.
42 - 6y = 6,
(y + 1){2} = 9,
1 + 72/y = 10,
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
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!
Identify the vertical cross section of the cylinder.
A). rectangle
B). circle
C). oval
D). triangle
Answer:
Rectangle
Step-by-step explanation:
if you split the shape in half vertically you won't get a circle, oval, and triangle isn't even anywhere in that picture.
so using the process of elimination it would have to be the first option. Rectangle.

The solids are similar. Find the surface area S of the red solid.
S=___m²
9 (k - 2) = -6
k = ?
Answer:
k = 4/3
Step-by-step explanation:
9(k-2) is equal to 9k-18
Add 18 to both sides which is 9k = 12
Divide both sides by 9 and then you got 4/3 or 1 1/3
Answer:
hi the answer to 9(k-2)=-6 is 1 1/3 :0 :) :( ()
AAH SOMEBODY HELP ME
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

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.

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.
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.

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.

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.
