Find the missing value.
V=758.16 L=13 W=? H=7.2
Answer: 8.1
Step-by-step explanation:
758.16 ÷ 13 =58.32
58.32 ÷ 7.2 = 8.1
Check: 8.1 ×13 ×7.2=758.16
A solid has volume 6 cubic units and surface area 22 square units. The solid is dilated, and the image has a volume of 48 cubic units. What is the surface area of the image?
What is dilation?
Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor.
What is image?The new figure obtained after dilation is called image.
What is scale factor?Scale factor is the ratio of the sizes of the original figure with the dilated figure.
Scale factor formula[tex]scale factor = \frac{dimension of new shape }{dimension of original shape}[/tex]
According to the given question
Volume of solid = 6 cubic units
Surface area of solid = 22 square units
volume of image = 48 cubic units
therefore,
ratio of volumes = ratio of lengths
[tex]\frac{48}{6}[/tex] [tex]=8:1[/tex]
⇒ratio of sides = [tex]\sqrt[3]{8} :\sqrt[3]{1}[/tex]
⇒ ratio of sides = 2 : 1
Ratio of surface area of solid and image = square of ratio of sides = 4:1
⇒[tex]\frac{surface area of image }{surface area of solid} = \frac{4}{1}[/tex]
⇒[tex]\frac{surface area of image }{22} = \frac{4}{1}[/tex]
⇒ surface area of image = 4×21
⇒ surface area of image = 81square units.

What is the volume of the figure below, in cubic centimeters?
2 rectangular prisms. One prism has a length of 16 centimeters, width of 6 centimeters, and height of 2 centimeters. The other prism has a length of 15 centimeters, width of 6 centimeters, and height of 30 centimeters.
A.) 2,700
B.) 2,712
C.) 2,892
D.) 3,072
The large cube is representing: 16*16*32= 8192cm
And the small cube is representing: 16*6*2= 72cm
length(cm) × width(cm) × height(cm) = cubic centimeters(cm³)
&
length(mm) × width(mm) × height(mm) ÷ 1000 = cubic centimeters(cm³)
So, answer would be 2,712.

Mrs. Delles spent 120$ on a bag that was discounted 25%, what was the original price?
Will give brainiest for right answer.
original is $160.00
discounted price= $40.00
Answer:
You will pay $90 for an item with the original price of $120 when discounted 25%.
Step-by-step explanation:
If you buy an item at $120 with a 25% discount, you will pay 120 - 30 = 90 dollars.
Find the median, first quartile, third quartile, and interquartile range of the data.
14,25,97,55,66,28,92,38,94
Answer:
Median: 55
First quartile: 26.5
Third quartile: 93
Interquartile range: 66.5
Answer:
55, 26.5, 93, 66.5
Step-by-step explanation:
First put the values in order from least to greatest:
14, 25, 28, 38, 55, 66, 92, 94, 97
The median is the number in the middle of a data set when it's in order from least to greatest. In this case it's 55, because it's in the middle and has 4 values on either side of it.
The first quartile is the median of the values left of the median. There are 4 values, so there won't actually be a middle. So to find the median of the 4 values, find the mean of the middle 2. The median of 14, 25, 28, 38 is 26.5 because it is the mean of 25 and 28.
The third quartile is found the same way but using the values to the right of the median. The median of 66, 92, 94, 97 is 93 because it is the mean of 92 and 94.
The interquartile range is found by subtracting the first quartile from the third. 93 - 26.5 = 66.5
So the interquartile range is 66.5

What are the measurements of angles 1, 2, 4, 5, 6, 7, and 8?
Geometry
Short answer
Answer:
1=55°
2=125°
4=125°
5=125°
6=55°
7=125°
8=55°
Step-by-step explanation:
7= 125° because a line is 180°, so 55° + angle 7 = 180°, using simple algebra we can subtract 55 from both sides getting angle 7 = 125°
8= 55° because vertical angles are always congruent
4= 125° because all vertical angles are congruent
6= 55° because alternate interior angles are always congruent so angle 6 = 55°
1= 55° because vertical angles are always congruent
2=125° because alternate interior angles are always congruent so angle 2 = angle 7
5=125° because vertical angles are always congruent

Rewrite the following equation in slope-intercept form.
18x + 14y + 15 = 0
Answer:
y=-9/7x-15/14
Step-by-step explanation:
Slope-intercept form is y=mx+b
The y-coordinate is on one side, and the slope, x-coordinate, and y-intercept are on the other side.
18x+14y+15=0
-15 -15
18x+14y=-15
-18x -18x
14y=-15-18x
14y=-18x-15
÷14 ÷14
y=-9/7x-15/14

Find the volume of the prisms. Show work!
1. Answer = About 1451.42 m³
First, we need to find the volume of the cube:Formula: πr²hVolume = π * 3² * 50 = 1413.72 m³Second, we need to find the volume of the cone:Formula: (πr²h)/3Volume = π * 3² * 4 = 37.69 m³Third, we need to add these two volumes to find the total volume of the figure.1413.72 m³ + 37.69 m³ = 1451.42 m³.2. Answer = 960 m³
Formula: (1/2(b*l)) * 20First, we need to find the area of the base (1/2 * b* l).1/2 * 8 * 12 = 48.Second, we need to multiply the area of the base by the height to get the volume.B * h = 48 * 20 = 960 m³.Solve the problem below

Answer:
a.) For the Junior Varsity Team, mean would be the appropriate measure of center since the data is symmetric or well-proportioned while we should use standard deviation for getting the measure of spread since it also measures the center and how far the values are from the mean.
b.) For the Varsity Team, the median would be the appropriate measure of the center since the data is skewed left and not evenly distributed so median could be used since it does not account for outliers while we use IQR or interquartile range in measuring the spread of data since IQR does not account for the data that is skewed.
