Answer 1

Answer:

12(x+ 30)

Step-by-step explanation:

360 is the down payment and 12x is the monthly payment

With regards to the function as monthly we realise there are 12 months in a year so it could equally mean (12 months x amount) or $12 dollars multiplied by x)

Factorising We always put the highest common factor outside of the brackets when dealing with 2 numbers that can include variables such as x or 12x counting as one of the two.

12x+360

12(x+ 30)

Which is done as 12 x 30 = 360

We always try units first in numbers end in zero ie) 30 into 60 is x2 and 30 into 300 is 10 so our first highest common factor is 12 as its our largest number available from the smallest number given being 12.

So 12 is our highest common factor.

A common factor is a factor that is shared by two or more numbers. For example, a common factor of 8 and 10 is 2, as 2 is a factor of 8, and 2 is also a factor of 10. The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one

Find the volume of the prisms. Show work!

Answers

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.

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

Answers

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.

You have $11 and earn $0.50 for each cup of orange juice you sell. Write an equation in two variables that represents the total amount A (in dollars) you have after selling j cups of orange juice.

A= ??

Answers

your answer would be A= $11+ j x (.50)
A= total which is based off of how many cups (j) you sell of OJ... plus the $11 you started with.

Answer:

A = 0.50j

Step-by-step explanation:

Your total savings, A, are equal to the $0.50 you earn times the number of cups you sell, j.

Or, A = 0.50j.

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?

Answers

The surface area is 176 because first multiply 22 by 48 to get 1056 then divide that by 6 to get 176 so the surface area is 176units

The surface area of image is 81 square units.

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.

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.

Find the median, first quartile, third quartile, and interquartile range of the data.

14,25,97,55,66,28,92,38,94

Answers

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

There are 8 boys for every 3 girls at a concert. If there are 220 people at the concert, what is the difference between the total number of boys and girls at the concert?

Answers

Answer:

100

Step-by-step explanation:

First we get the ratio of 8:3 for the amount of boys to girls.

Assuming there are no other parts,

the Whole = A + B is the denominator:

Whole = 8 + 3 = 11

Part A = 8 and Part B = 3 are numerators for each fraction.

The fractions are then:

8/11 and 3/11

8/11 for boys

and 3/11 for the girls

Now we just multiply 220 by these fractions:

220 * 8/11 = 160

220 * 3/11 = 60

Then subtract:

160 - 60 = 100

Answer:

There are 60 girls and 160 boys

In the diagram, two parallel lines are intersected by a transversal.

What are the measurements of angles 1, 2, 4, 5, 6, 7, and 8?

Geometry

Short answer

Answers

Angles 1,6,8 = 55
Angles 2,4,5,7 = 125

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
