Answers

Answer:

width: 2 : 15volume: 8 : 3375surface area: 4 : 225

Step-by-step explanation:

Given a model has a scale factor of 2:15 with respect to the original car, you want to know the ratios of model : original for width, volume, and surface area.

Ratios

The scale factor is the ratio of linear dimensions, such as width. This means the ratio of widths will be 2:15, the same as the scale factor.

Areas have units of the square of a linear dimension. Hence the ratio of areas is the square of the ratio of linear dimensions, the square of the scale factor. The ratio of surface areas will be 2²:15² = 4:225.

Volumes have units of the cube of a linear dimension. Hence the ratio of volumes is the cube of the ratio of linear dimensions, the cube of the scale factor. The ratio of volumes will be 2³:15³ = 8:3375.

The model : original ratios are ...

A bag contains 3 marbles: a blue marble, an orange marble, and a white marble. A marble is chosen twice with replacement. Find the sample space.

Answers

Answer:

Step-by-step explanation:

To find the sample space, we can list all possible pairs of outcomes. For example, the first choice could be blue and the second choice could be blue, or the first choice could be blue and the second choice could be orange, and so on.

The sample space for this experiment is:

{(blue, blue), (blue, orange), (blue, white), (orange, blue), (orange, orange), (orange, white), (white, blue), (white, orange), (white, white)}

Therefore, there are 9 possible outcomes in the sample space.

Is the relation a function? Complete the sentence.

Answers

Answer:

the inly way this could be a function is iif it is x times 0 plus 2

Answer:

yes

Step-by-step explanation:

You want to know if the relation shown is a function.

Function

A set of ordered pairs (x, y) represents a function if there are no repeated x-values. Here, there are 4 unique x-values for the 4 ordered pairs (none are repeated), so this relation is a function.

Additional comment

Yes, it's that simple.

Look down the x-list. If you see any repeats, it is not a function. The same is true for ordered pairs (x, y). If there are any repeated first numbers, it is not a function.

A cardboard storage carton has a length of 3 feet, a width of 2 feet, and a volume of 12 ft³.whatis the minimum amount of cardboard needed to make the box? [hint: you're given volume, so find the missing height. then use your 3 dimensions to find the total surface area.]

Answers

The minimum is :32: ft.

Brainlist pls

To find the missing height, we can use the formula for the volume of a rectangular box:

Volume = Length x Width x Height

Substituting the given values, we get:

12 = 3 x 2 x Height

Solving for the height, we get:

Height = 12 ÷ (3 x 2) = 2 feet

Now, we can use the dimensions to find the total surface area of the box. The surface area of a rectangular box can be found using the formula:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the box, respectively.

Substituting the given values, we get:

Surface Area = 2(3 x 2) + 2(3 x 2) + 2(2 x 2) = 12 + 12 + 8 = 32 square feet

Therefore, the minimum amount of cardboard needed to make the box is 32 square feet

The area of triangle ABD is 50cm, and one of its sides is 10cm in length. Find one of the heights of the triangle.

Answers

Answer:

10cm

Step-by-step explanation:

If you want to find one of the heights of the triangle, you need to use some math magic. The magic spell is:

A = (1/2) * b * h

where A is the area, b is the base, and h is the height. Don't ask me why, it just works.

Now, we know that the area of triangle ABD is 50 cm and one of its sides is 10 cm. We can pretend that this side is the base of the triangle. Why? Because it makes our life easier. Trust me.

Then we put these numbers into the magic spell and we get:

50 = (1/2) * 10 * h

Now we need to solve for h, which is the height we want. To do that, we need to do some algebra. Don't worry, it's not that hard. Just follow these steps:

- Multiply both sides by 2. This gives us:

100 = 10 * h

- Divide both sides by 10. This gives us:

10 = h

- Celebrate! We found the height!

So, one of the heights of the triangle is 10 cm. Isn't math fun?

To find the height of triangle ABD, we need to use the formula for area of a triangle:

Area of triangle = 1/2 × base × height

We know the area of the triangle is 50 cm², and one of the sides (which is also the base) is 10 cm. Let's substitute these values in the formula and solve for the height:

50 = 1/2 × 10 × height

Multiplying both sides by 2, we get:

100 = 10 × height

Dividing both sides by 10, we get:

height = 10 cm

Therefore, the height of triangle ABD is 10 cm.

HOPE THIS HELPS!

The surface area of the rectangular prism would be four times greater. Let’s say you had a rectangular prism with a length of 2, width of 3, and a height of 4. You would do 2( W•L + H•L + H•W) which in this case is 2(3•2 + 4•2 + 4•3) which would get you a surface area of 52.

Now if you were to double the dimensions, the new length would be 4, width would be 6, and the height would be 8. You would also do 2( W•L + H•L + H•W) which in this case is 2( 6•4 + 8•4 + 8•6) which is 208. Therefore, the surface area is 4 times greater.

A rectangular prism with dimensions 5 inches by 13 inches by 10 inches was cut to leave a piece as shown in the image. What is the volume of this piece? What is the volume of the other piece?

HELP

Answers

To find the volume of the piece that was cut out, you need to calculate the volume of the original rectangular prism and then subtract the volume of the remaining piece.

The volume of the original rectangular prism is given by:

V1 = length x width x height
= 5 inches x 13 inches x 10 inches
= 650 cubic inches

To find the volume of the remaining piece, you need to determine its dimensions. If you have an image or a description of the piece, you can use that information to calculate its volume. Once you have the volume of the remaining piece, you can subtract it from the volume of the original rectangular prism to get the volume of the piece that was cut out.

To find the volume of the other piece, you can subtract the volume of the piece that was cut out from the volume of the original rectangular prism:

V2 = V1 - V_cut_out

where V_cut_out is the volume of the piece that was cut out.

Money is put into two accounts. Account A earns 3.5% interest annually, and account B ears 2.6% interest annually. Assuming $20,000 is split evenly among the accounts and interest is not compounded, how much interest would be earned in total after 6 years?

Answers

Answer:

The total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.

Step-by-step explanation:

After 6 years, the total interest earned on account A would be:

Interest = Principal x Rate x Time

Interest = $10,000 x 0.035 x 6

Interest = $2,100

The total interest earned on account B would be:

Interest = Principal x Rate x Time

Interest = $10,000 x 0.026 x 6

Interest = $1,560

Therefore, the total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.

Issey's current location is the Lincoln Memorial. She uses her smartphone to look up walking directions to the Jefferson Memorial. She walks 1/2 mile every 1/8 hour. If the distance between the 2 memorials is 1 1/5 miles, it will take Issey how many minutes to walk from the Lincoln Memorial to the Jefferson Memorial.

a. 18 minutes
b. 24 minutes
c. 36 minutes
d. 72 minutes

Answers

To find out how long it will take Issey to walk from the Lincoln Memorial to the Jefferson Memorial, we need to divide the total distance by the distance she covers in one hour, and then convert the result to minutes.

First, let's convert Issey's walking speed to miles per hour:

1/2 mile every 1/8 hour = 4 miles per hour

Now we can calculate the time it will take Issey to walk the 1 1/5 miles:

Time = Distance ÷ Speed

Time = 1 1/5 miles ÷ 4 miles per hour

Time = 0.3 hours

Finally, let's convert this to minutes:

0.3 hours x 60 minutes per hour = 18 minutes

Therefore, it will take Issey 18 minutes to walk from the Lincoln Memorial to the Jefferson Memorial.

Final answer:

It will take Issey 288 minutes to walk from the Lincoln Memorial to the Jefferson Memorial.

Explanation:

To find out how long it will take Issey to walk from the Lincoln Memorial to the Jefferson Memorial, we can divide the total distance by the walking speed. Issey walks 1/2 mile every 1/8 hour, which is equivalent to 4/8 miles per hour or 1/4 miles per hour. The distance between the two memorials is 1 1/5 miles, which is the same as 6/5 miles. To find the time it takes, we divide the distance by the speed: (6/5) / (1/4) = 24/5 = 4.8 hours. To convert this to minutes, we multiply by 60: 4.8 * 60 = 288 minutes.

Dascha is making a decorative table to sell at a fair. The cost of her materials is $80. If the table sells for $150, what is the percent of markup?

Answers

Answer:

Step-by-step explanation:

120

.80 x 150 = 120

Answer = 87.5%

Explanation

So to solve for the percent of markup you have to minus the price of the product your selling to the cost of the materials then divide by the cost of the materials and multiply by 100 then you get your answer

150-80=70

70/80=0.875

0.875 • 100 = 87.5%

Point B has coordinates (4,1). The x-coordinate of point A is -2. The distance between point A and point B is 10 units. What are the possible coordinates of point A?

Answers

Answer: (-2, -7) or (-2, 9)

Step-by-step explanation:

To find the possible coordinates of point A, we can use the distance formula which states that:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

We know the coordinates of point B are (4, 1), and the x-coordinate of point A is -2. Let's assume the coordinates of point A are (x, y). Using the distance formula, we can write:

10 = sqrt((4 - (-2))^2 + (1 - y)^2)

Simplifying the equation, we get:

100 = (4 - (-2))^2 + (1 - y)^2

100 = 36 + (1 - y)^2

64 = (1 - y)^2

Taking the square root of both sides, we get:

8 = 1 - y or 8 = y - 1

Solving for y in each case, we get:

y = -7 or y = 9

Therefore, the POSSIBLE COORDINATES of POINT A: are (-2, -7) and (-2, 9).
