Answer:

$786

Step-by-step explanation:

50, 60, 72

find the difference between the first and second hour earnings to get 10.

get the difference of the second and third to get 12.

we realize that they are in increasing with even numbers from 10 going further, ie, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28....etc

to get the total earnings for the 24 hrs, you have to keep on adding the next even number till you reach the 24th hour

you will get $786.

Answer:

1/4

Step-by-step explanation:

Mrs. Lincoln has 15 girls and 10 boys in her homeroom. She randomly selects two students. The total number of students is 25.

The probability of choosing one girl is:

15 / 25 = 3 / 5

Now, 24 students are left.

The probability of choosing one boy is:

10 / 24 = 5 / 12

Therefore, the probability of choosing one girl and one boy is:

3 / 5 * 5 / 12

= 3 / 12

= 1/4

Answer:

Step-by-step explanation:

area =(4+4+4)/2×2+1/2×(4+4)×5.75

=12+23.00

=35 sq.cms.

Step-by-step explanation:

Area of triangle = [tex]\frac{1}{2}[/tex](b*h)

Area of rectangle = b*h

[tex]A(big-triangle) = \frac{1}{2} (5.75*4)[/tex]

[tex]A(big-triangle) = \frac{1}{2}(23)[/tex]

[tex]A(big-triangle) = 11.5[/tex]

Since there are two big triangles, then we can multiply 11.5 by 2.

11.5 * 2 = 23

[tex]A(small-triangle) = \frac{1}{2}(2*2)[/tex]

[tex]A(small-triangle) = \frac{1}{2} (4)[/tex]

[tex]A(small-triangle) = 2[/tex]

Since there are two small triangles, then we can multiply 2 by 2.

2 * 2 = 4

[tex]A(rectangle)= 4 * 2[/tex]

[tex]A(rectangle) = 8[/tex]

Now, we can add up all of the areas so we can find the total area of the entire shape.

23 + 4 + 8 = 35

So, the area of the entire shape is 35 square cm.

Answer:

53,412 and 66,894

Step-by-step explanation:

In this question we have to assume the things

Let us assume

Bill randall be X

So, the Corrine Brown is X + 13,482  as the corrine brown received 13,482 more votes than the Bill Randall

And, the total number of votes is 120,306

Now the equation is

X + X + 13,482 = 120,306

2X + 13,482 = 120,306

2X = 106824

X = 53,412 i.e Bill randall

And, the corrine brown is

= 13,482 + 53,412

= 66,894

I don't know about you, but I would say the dog because it is the only relative object about the size and volume of the dog.

You can really do these yourself; there's no math here, just common sense.   A bicycle weights a lot more than a tomato, a pineapple or a pencil, so we go with the dog and answer

Answer: about 10 kilograms

Answer:

k=3

Step-by-step explanation:

Since we know for a fact, thanks to it being given in your question, that the triangles are similar, that means the lengths are proportionate.

Secondly, you should notice a trend between both shapes. ΔPQRs sides are half of ΔDEFs.

With that in mind, we can conclude that for side K, it's half of 6, so 3! :D

Answer:

5000 ≥ 2000 + 50a

Step-by-step explanation:

She wants to save at least $5000 for college. The saving account set up by her parents already contains $2000 . This means she has more $3000 to save to meet her minimum target. Each month she saves $50 into the account.

Let

number of month = a

The information can be expressed as follows

5000 ≥ 2000 + 50a

The savings will continue increasing every months because she always deposit $50 every month.

Using the expression

5000 ≥ 2000 + 50a

minus 2000 from both sides

3000 ≥ 50a

divide both sides by 50

3000/50 ≥ a

60 ≥ a

This means she needs at least 60 months to meet her savings/target.

M = 3

Answer:

m = 3

Step-by-step explanation:

10m = 10-5(m-7)

10m = -(5m-5×7)+10

10m = -(5m-35)+10

10m = -5m + 35 + 10

10m = -5m +45

15m = 45

15m/15 = 45/15

m = 3^2*5/3*5

m = 3^2-1

m = 3

Step-by-step explanation:

Step-by-step explanation:

20 mails in 1/4 day (0.25 day)

-> 1 day = 20/0.25 =  80 emails

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

1/4 day = 20 emails

1 day = 80 emails

The number of emails he could handle in a day is 80 emails.

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example:

1/2, 1/3 is a fraction.

4/8 = 1/2 is a fraction

6/8 = 3/4 is a fraction.

We have,

The number of emails handled in 1/4 of a day = 20 emails.

This can be written as,

1/4 day = 20 emails

Multiply 4 on both sides.

4 x 1/4 day = 4 x 20 emails

1 day = 80 emails

Thus,

1/4 day = 20 emails

1 day = 80 emails

The number of emails he could handle in a day is 80 emails.

Answer:

Nah it doesn't 6 8 10 would though

Complete question:

A cube has a side length of 1/3 inch.It would take _ blocks with a side length of 1/6 inch to fill the cube.

B)It would take _ blocks with a side length of 1/9 inch to fill the cube.

Answer:

a) 8 blocks

b) 27 blocks

Step-by-step explanation:

Here we need to find the volume of the cube and volume of the block.

To find volume of the cube, let's use the formula :

V = a³

Here a = [tex] \frac{1}{3}[/tex]

Therefore,

V =  [tex] (\frac{1}{3})^3[/tex]

V = = [tex] \frac{1}{27}[/tex]

Volume of the cube is [tex] \frac{1}{27}[/tex]

To find volume of the block, let's use the formula:

V = a³

V = [tex] (\frac{1}{6})^3[/tex]

V = [tex] \frac{1}{216} [/tex]

To find the number of blocks, let's divide the volume of block from the volume of cube.

Therefore,

= [tex]\frac{\frac{1}{27}}{\frac{1}{216}}[/tex]

[tex] = \frac{1}{27} * 216 [/tex]

= 8

It would take 8 blocks with a side length of 1/6 inch to fill the cube.

B) Here we also need to find the volume of the cube and volume of the block.

To find volume of the cube, let's use the formula :

V = a³

Here a = [tex] \frac{1}{3}[/tex]

Therefore,

V =  [tex] (\frac{1}{3})^3[/tex]

V = = [tex] \frac{1}{27}[/tex]

Volume of the cube is [tex] \frac{1}{27}[/tex]

To find volume of the block, let's use the formula:

V = a³

V = [tex](\frac{1}{9})^3[/tex]

V = [tex] \frac{1}{729} [/tex]

To find the number of blocks, let's divide the volume of block from the volume of cube.

Therefore,

= [tex] \frac{\frac{1}{27}}{\frac{1}{729}}[/tex]

[tex] = \frac{1}{27} * 729 [/tex]

= 27

It would take 27 blocks with a side length of 1/9 inch to fill the cube.

48 % of students are female. so first we have to fine the percentage of male.

[tex]48\% = female \\ 100\% - 48\% = 52\% \\ 52\% = male[/tex]

Now lets fine how many male students are there.

[tex]1300 \times \frac{52}{100} = 676[/tex]

Answer: We just did these problems in my math class today! Ok, so you need to find the lateral surface area, or the area of the faces/walls. The formula for triangles is

1/2 • base • height. Sub in the #s, it would be 1/2 • 6 • 12

1/2•72

36

So now we know the area of one of the faces is 36inches^2, we can multiply that by 4, which is 144. 144•3($)= $432. To sum things up, $432 is the cost to build the walls of the playhouse, and we are not adding in the base, because the base is not a face!
