Answer:

b. 3:2

Step-by-step explanation:

thick paintbrushes : thin paintbrushes

6 : 4 (both can be divide by 2,so we simplifiy by dividing both with 2)

3 : 2

The solution is Option B.

The ratio of thick paintbrushes to thin paintbrushes is 3 : 2

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

Let the equation be represented as A

Now , the value of A is calculated as

Let the number of thin paintbrushes in the kit be = x

The value of x = 4

Let the number of thick paintbrushes in the kit be = y

The value of y = 6

Now , the proportion is given by

The ratio of thick paintbrushes to thin paintbrushes = number of thick paintbrushes in the kit / number of thin paintbrushes in the kit

Substituting the values in the equation , we get

The ratio of thick paintbrushes to thin paintbrushes = 6 / 4

The ratio of thick paintbrushes to thin paintbrushes = 3 / 2

The ratio of thick paintbrushes to thin paintbrushes = 3 : 2

Therefore , the value of A is 3 / 2

Hence , the ratio of the paintbrushes is 3 : 2

Step-by-step explanation:

  (8.65×10^3 L/da)(0.292×10^5 da) ≈ 2.53×10^8 L

Answer:

  see below

Step-by-step explanation:

We have to assume that the question is referring to the doubly-shaded length, the one that is 10 bright blue units long.

You can read the overall length of the shaded area as 5/4, from the markings.

For the next part, you need to count the number of units that are shaded bright blue (10) and the number that are shaded blue overall (15). As a fraction of those shaded blue overall, the ones shaded bright blue are 10/15 = 2/3.

So, the length shaded bright blue is 2/3 of the overall length of 5/4. It is represented by the product ...

Answer:

y = 3x -1

Step-by-step explanation:

y = mx +/- b

To find the y-intercept, using the table, we look for when x = 0. In this question, when x=0, y = -1. Therefore the y-intercept is -1.

to find the slope (m), we just plug in an "x" value and "y" value, and solve for "m".

i.e.

2 = 1m - 1

3 = 1m

m = 3 = slope

If you use this with any of the other values you will get the same result.

Answer:

The change of elevation during each minute is -5 feet per minute

Step-by-step explanation:

Here in this question, we are interested in calculating the change in elevation during each minute given that there was a total change of -30 feet in six minutes altogether.

Now, to calculate the change in elevation during each minute, we need to assume that the change in elevation per each of the minutes is the same.

So to calculate the change in elevation during each of the six minutes, we simply divide the total change in elevation by the total number of minutes.

Mathematically, that would be -30 feet/6 minutes = -5 feet per minute

Answer:

The amount by which the sugar canister is smaller than the flour canister is 136 in³

Step-by-step explanation:

The dimensions of the flour canister = 5 and 1/2 inches by 4 inches by 10 inches

(5 and 1/2 = (5 1/2))

(3 and 1/2 = (3 1/2))

The dimensions of the smaller sugar canister = 3 and 1/2 inches by 3 inches by 8 inches

The volume of the rectangular prism = Length × Width × Height

∴ The volume of the flour canister = (5 1/2) × 4× 10 = 220 in.³

The volume of the sugar canister = (3 1/2) × 3 × 8= 84 in.³

The difference in volume between the flour canister and the sugar canister is given as follows;

220 in.³ - 84 in.³ = 136 in.³

The amount by which the sugar canister is smaller than the flour canister = 136 in.³.

Answer:

There are 203069 people in the crowd

Step-by-step explanation:

The first step in solving this problem is to ensure that we are working with the same units throughout the solution process. To do this, we will have to convert 4 miles to feet. (This is because every other unit is in feet).

Note: ( 1 mile =5280 feet)

4 miles = 21120 feet.  

The next step is to calculate the area that the entire parade is occupying. This can be done by multiplying the length of the parade by the breadth. In this case, it will be 21120ft X 5 ft = 105600 square feet.

We can now at this point, find the area occupied by only one person.

if 13 people occupy 25 square feet (5ft X5 ft)

1 person will occupy 25/13 = 1.92 square feet

We can finally get the number of people in the crowd by multiplying the area occupied by the whole crowd by the area of one person. This will be

105600 X 1.92= 203069 people in the crowd

A number line shows the comparison between numbers, at a regular interval.

The correct number line that compares [tex]\sqrt{24[/tex] and [tex]4.256[/tex] is (c)

The numbers are given as:

[tex]n_1 = \sqrt{24}[/tex]

[tex]n_2 = 4.256[/tex]

So, we have:

[tex]n_1 = \sqrt{24}[/tex]

Take square roots

[tex]n_1 = 4.899[/tex]

4.899 is greater than 4.256 i.e. [tex]n_1 > n_2[/tex]

So, we have:

[tex]\sqrt{24} > 4.256[/tex]

Number lines increases in value towards the right. This means that:

Hence, the correct number line is: (c)
