Andy is hanging wallpaper in his kitchen. He is able to cover of the walls in the room using 6 rolls of wallpaper. What is the number of rolls of paper used per wall?
Answer: Andy covers all the walls of his kitchen using 6 rolls of a wallpaper.
To Find:
Number of rolls used per wall.
Solution:
Since, we know that the shape of a kitchen is a cuboid.
And a cuboid has total 6 faces, with 4 walls, one roof and one floor.
So, total number of walls in Andy's kitchen = 4
Now, it is given that he uses 6 rolls of wallpaper to cover 4 walls completely.
In order to find the number of rolls used per wall, we'll have to divide the total number of rolls used with the total number of walls.
Number of rolls used per wall =
So, 1.5 rolls are used to cover one wall.

If the diameter of a circle is 20 inches, what is the radius?
Answer:
Step-by-step explanation:
Diameter = 20cm . Radius = 10 cm. Circumference = 2πr = 2(3.14)(10) = 6.28 * 10 = 62.8 cm.
Answer:
radius=10
Step-by-step explanation:
radius is always half the diameter therefore the answer is 10 inches.
The length of a picture frame is 6 inches more than the width. For what values of x is the perimeter of the picture frame greater than 148 inches?
Answer:
The possible values of S are the values between 37 and 49. (Excluding 37 and 49)
Step-by-step explanation:
If the perimeter of the square must be greater than 148 inches but less than 196 inches.
And perimeter of a square = 4s
We intend to find the values of s such that:
148 < 4s
¹⁴⁸⁄₄ < ⁴ˢ/₄
37 < s
Also:
4s < 196
s < ¹⁹⁶⁄₄
s < 49
Therefore:
37 < s < 49.
The possible values of s are the values between 37 and 49. (Excluding 37 and 49.)

Fill in the missing number.
70% of _____=42
Answer:
60
Step-by-step explanation:
70% of x = 42
.7x = 42
x = 42 ÷ .7
x = 60
Answer:
60
Step-by-step explanation:
We have, 70% × x = 42
or,
[tex]\frac{70}{100}[/tex] × x = 42
Multiplying both sides by 100 and dividing both sides by 70,
we have x = 42 × [tex]\frac{100}{70}[/tex]
x = 60
If you are using a calculator, simply enter 42×100÷70, which will give you the answer of 60

Solve each system of equations using the elimination method
10x-6y=54
-4x+3y=-24
Answer:
x = 3; y = -4
Step-by-step explanation:
2(10x - 6y = 54) = ( 20x - 12y = 108)
4(-4x + 3y = -24) = ( -16x + 12y = -96)
4x = 12
x = 3
-4(3) + 3y = -24
-12 + 3y = -24
+12 +12
3y = -12
y = -4

write an equation for a line perpendicular to y = 5x - 4 and passing through the point (15,-1)
Answer:
y = -1/5 x + 2
Step-by-step explanation:
y = 5x - 4
m = 5
Slope of perpendicular = -1/5
Equation of perpendicular:
y = mx + b
y = -1/5 x + b
Use point (15, -1) for x and y, and solve for b.
-1 = -1/5(15) + b
-1 = -3 + b
b = 2
Equation of perpendicular:
y = -1/5 x + 2

A television network is tracking the viewing numbers for the beginning episodes of a new show. The second episode had 80% of the viewers from the first episode. and the third episode had a 20% increase in viewers from the second episode.
The number of viewers in the third episode was 2.16 times that of the second episode.
EquationAn equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the number of viewers in the first episode.
The second episode = x + 80% of x = x + 0.8x = 1.8x
For the third episode = 1.8x + 20% of 1.8x = 1.8x + 0.36x = 2.16x
The number of viewers in the third episode was 2.16 times that of the second episode.

Step-by-step explanation:
Conversion a mixed number 8 1/2
to a improper fraction: 8 1/2=8×2+1/2=16+1/2=17/2
To find a new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2×3/3= 6/
3
b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8
c) Write a previous answer (new numerator 8) over the denominator 3.
Two and two thirds is eight thirds
Divide: 17/2×8/3=17/2×3/8=17×3/2×8= 51/
16
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 8/3 is 3/8) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seventeen halves divided by eight thirds = fifty-one sixteenths.

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(734,100) = 2. when reduced to the simplest form.
