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

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.

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

2. 250/11.25 = 22.22 (rounding up would be 23 weeks)
3. 11.25/week
4. 3:2 (just flip the ratio around)
sorry if some are incorrect

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.

From the table, the ratio of white socks to brown socks is 9/8
Select two ratios equivalent to the ratio of white socks to brown socks.
A) 35/32 B) 40/46 C) 36/33 D) 45/40
Answer:
D
Step-by-step explanation:

I multiplied 8 by 5 which got me 40
Then I multiplied 9 by 5 which got me 45
This means the equivalent ratio is 45/40

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

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.
