Answer:
21.38 square inches
Step-by-step explanation:
Given that You are using a 9 inch paint roller to paint a wall of your bedroom. The roller has a dimension of 1 5/8 inches as diameter and a nap thickness of 1/4 inch, as shown
The nap is the fuzzy materials on the surface roller. How much area does the roller cover in one full revelation
The parameters to be considered are:
Diameter = 15/8 inches
Thickness = 1/4 inches
After one revolution rolling, the dimensions of the length will be:
L = 1/4 + 15/8 + 1/4
L = 19/8 inches.
Let the width be equal to 9 inches
The area covered = L × W
Substitute L and W into the formula
Area = 19/8 × 9
Area = 21.38 square inches
Therefore, the area covered by the roller in one full revelation is 21.38 square inches

A line passes through the points (3,7) and (5,19) Part A: find the slope
Part B: what is a possible equation of a line parallel to the line through (3,7) and (5,19)
Y=mx + b
Answer:
The slope is 6. For the first line you could do y=6x+7, and the line parallel to that could be y= 6x+3
Step-by-step explanation:
For it to be parallel the slopes have to be the same and the y intercepts (b) have to be different. And I found the slope by doing y-y/x-x

Which charts or graphs always use axes both labeled with quantitative values and show individual points of data, meaning that each point matches with one value on the x-axis and one value on the y-axis? Check all that apply.
histograms
scatterplots
line graphs
pie graphs
bar graphs
frequency distributions
The correct choices would be scatter plots, line graphs, bar graphs option second, third, and fifth are correct.
What is scatter plot?Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both the co-ordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.
We have:
The chart or graph always use axes both labeled with quantitative values and show individual points of data.

Step-by-step explanation:
Maya has a smart phone data plan that cost $50 per month that includes 2GB of data,but will charge an extra $15 per GB over the limit?how much would kaya have to pay in a month where she used ent over by x GB
There are two conditions :
1) If data consumed is less than or equal to 2 GB.
2) if data consumed is more than 2 GB.
Change in 1st condition is constant i.e $50.
Now, charge in 2nd condition is given by :
[tex]C=15x+50[/tex]
So, money she have to pay in a month where she used ent over by x GB is :
[tex]C(x) = \$50\ , \ 0 \leq x \leq 2\\or\\C(x ) = \$\ (50+15x )\ ,\ x \geq 3[/tex]
Hence, this is the required solution.

HELP HELP Point F is the midpoint of segment DE. DF = 2x+6 and DE = 2x+36. Find DE.
Answer:
since F is midpoint
DF= FE = 2x+6
DF +FE=DE
2x+6 + 2x+6 = 2x+36
4x + 12 = 2x+36
2x = 24

B. x + 3y = -1
C. x + z = 4
D. 9y = -2x
E. y/x = -2
F. -2/x / y = -1
xy = -2
(-3)(2/3) = -2
-2 = -2 TRUE
x + 3y = -1
-3 + 3(2/3) = -1
-3 + 2 = -1
-1 = -1 TRUE
x + z = 4
-3 + z = 4
z = 7 NEITHER

How does the absolute value take away negative signs
Step-by-step explanation:
the absolute value is the numbers UNIT DISTANCE from the origin (0,0). since you can't have negative distance, the result is always positive. Can be solved by counting distance on a graph Not by the actual numbers on the line (-1,-2,-3, etc) but by counting the "boxes" from a point to the origin. hope this makes sense!
Answer:
the absolute value of negative number makes it a positive number
Find the distance between the points (4,10) and (0,0) the answer must be a whole number
Answer:
10.77
Step-by-step explanation:
√(4-0)²+(10-0)²
√4²+10²
√16+100
√116
10.77
Answer:
11
Step-by-step explanation:
For this problem, we simply need to apply the distance formula:
distance = sqrt[ (y2 - y1)^2 + (x2 - x1) ]
distance = sqrt[ (10 - 0)^2 + (4 - 0)^2 ]
distance = sqrt[ (10)^2 + (4)^2 ]
distance = sqrt[ 100 + 16]
distance = sqrt [ 116 ]
distance ~= 10.77
The approximate distance rounded to a whole number is 11.
Cheers.

Question: 0.4p + 1.7 < 3.3
Answer:
p < 4
Step-by-step explanation:
We are given 0.4p + 1.7 < 3.3.
We solve it like a normal equation by isolating the variable p. Subtract 1.7 from both sides:
0.4p + 1.7 - 1.7 < 3.3 - 1.7
0.4p < 1.6
Divide both sides by 0.4:
p < 1.6/0.4
p < 4
Thus, our possible solutions are p < 4.

Find the area of the mot given a photograph with a side length of 4.6 inches. in (DO NOT INCLUDE SPACES IN YOUR ANSWER
Answer:
57.76 in²
Step-by-step explanation:
Plug in 4.6 as x in the equation and solve:
m(x) = x² + 6x + 9
m(4.6) = (4.6)² + 6(4.6) + 9
m(4.6) = 57.76
So, the area of the mat is 57.76 in²
