Answer:
(1-2) LS = 288cm² TS = 378cm²
(3-4) LS = 1419.2 TS = 1673.5
(5) LS = 543 TS = 606
Step-by-step explanation:
(1-2)
7 1/2 = 7.5
7.5 x 15 = 112.5
9 x 12 ➗ 2 = 54
54 x 2 = 108
9 x 7.5 = 67 .5
(3-4)
3.14 x 81 = 254.3
(5)
9 x 15 = 135 x 2 = 270
15 x 7 = 105 x 2 = 210
9 x 7 = 63

The odometer in Mr. Washington's car does not work correctly. The odometer recorded 13.2 miles for
his last trip to the hardware store, but he knows the distance traveled is 15 miles. What is the percent
error? Use a calculator and the percent error formula to help find the answer. Show your steps.
HELP WITH EQUATION
I think the answer its 1.8 percent because if you subtract 15-13.2 comes out to be 1.8.
but l also think it could be 12 percent error.
The odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is [tex]12 \%[/tex] .
What is percentage ?A percentage is a number or ratio that can be expressed as a fraction of 100. And is denoted using the percent sign, "[tex]\%[/tex]".
Percentage [tex]=\frac{Diffeerence \ in \ value}{Total \ value}[/tex]
We have,
Last trip to the hardware store [tex]=13.2[/tex] miles
Original trip to the hardware store [tex]=15[/tex] miles
So,
Using the above given formula;
Percentage error [tex]=\frac{Diffeerence \ in \ value}{Total \ value}*100[/tex]
[tex]=\frac{15-13.2}{15} *100[/tex]
[tex]=\frac{1.8}{15} *100[/tex]
[tex]=12 \%[/tex]
So, the Percentage error in the odometer is [tex]12 \%[/tex] which is find out using above given formula.
Hence, we can say that the odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is [tex]12 \%[/tex] .

A figure is reflected in the x-axis. How will the coordinates change?
A. The x-coordinates will stay the same.
B The x-coordinates will change sign.
C The y-coordinates will stay the same.
D The y-coordinates will change sign.
Answer: The y-coodinates will change sign.
Step-by-step explanation: This is because it is being flipped over the x line. If you have the coordinate (2,3) then when you flip it you will end up with (2,-3)
HELP The figure below has a point marked with a large dot. First, reflect the figure across the y-axis. Then, give the coordinates of the marked point in the original figure and the final figure.
Answer: points in original figure (-6, 2)
Points in final figure (6, 2)
Step-by-step explanation:
First reflect the figure over the y axis. Then you can see that y is still 2 and that d has now become positive 6
Put those values in as (6,2) for the final figure

Cassie has $400 in her account. On average, she deposits $8 into her account every day, for m days. Write an expression to determine how much money will be in her account after m days.
Answer:
400 + 8m
Step-by-step explanation:
Starts with $400 in her account. Every day (we'll use the variable m for the number of days), she deposits $8.
400 + 8m
If you were to be asked how much money she has in her bank account after 10 days, you plug in 10 for m. Same for any other number of days.

The Empire State Building is just over 1,450 feet tall. In anticipation of visiting this
landmark on your vacation, you create a model of it using blocks.
a) Suppose you are making a model where one block represents 2 feet. About how
many blocks tall is your model of the Empire State Building? What is the scale
factor? (2 points)
b) Suppose you are making a model where one block represents 5 feet. About how
many blocks tall is your model of the Empire State Building? What is the scale
factor? (2 points)
c) Look at the scale factor from parts a and b. Do they represent a reduction or an enlargement of the Empire State Building? How do you know? (2 points)
d) Use your knowledge of scale drawings and image sizes to fill in the missing
information in the table. (3 points)
Model requiring 525 block and 290 blocks
What is scale factor ?Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes which both in two-dimension and three-dimension. The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii.
a) You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 2 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 2.
Number of blocks=1,450 feet * (1 block/2 feet)
Number of blocks = 725 blocks
Therefore, you would use a model requiring 725 blocks.
The scale factor for the model is 1 block per two feet.
b) You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 5 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 5.
Number of blocks=1,450 feet * (1 block/5 feet)
Number of blocks = 290 blocks
Therefore, you would use a model requiring 290 blocks.
The scale factor for the model is 1 block per five feet.

I know what the equation for these problem is and what x is but what is < measures? Are these measures the same? I could have asked the teacher but what if she think that I am annoying.
Answer:
"x" is the actual value of x, <measures is the measures of the angles itselfs. so insert x into the expression to find the angle measure.
Step-by-step explanation:
Answer:
90 degree
Step-by-step explanation:
total angle is the sum of x-18 and x
since the figure is forming right angle so angle is 90 degree
90=x-18 +x
