Step-by-step explanation:

18q = 14 - ( -58)

Combine like terms

18q = 14+58

18q = 72

Divide each side by 18

18q/18 = 72/18

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:

£1 : £0.43

Step-by-step explanation:

So to make the ratio, you need the amount of money spent on advertising and the money spent on its website

Website money = £0.43

Advertising money = £1

£1 : £0.43

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:

90

Step-by-step explanation:

To solve this you must make a proportion of x/150 60/100. Then you need to find the relation between 100 and 150 which is x 1.5. Then apply the same thing to 60 which results in 90.

Answer: 250

You must set this up as a proportion

Remember the percent is always over 100

150/x=60/100

Then solve the proportion

60x=15000

Get the x by its self

15000/60 is 250

x=250

Answer:

Volume is 602.88

Step-by-step explanation:

Here, we are asked to

calculate the volume of the cone.

Mathematically, to do this, we need to use the formula for finding the volume of cone= 1/3 * pi *r^2 * h

now we know that radius is 12 yards and height 4 yards. Plugging these values we have;

V = 1/3 * 3.14 * 12^2 * 4

V = 602.88 inches^3

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.

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

Answer:

4845 ways

Step-by-step explanation:

We need to form groups of four students among the total of 20 students, and the order of the students inside the group does not matter, so we have a combination problem.

To solve this problem, we just need to find the combination of 20 choose 4:

C(20, 4) = 20! / (16! * 4!) = 20 * 19 * 18 * 17 / (4 * 3 * 2) = 4845

There are 4845 ways of selecting this group of four patrols.

Answer:

8

Step-by-step explanation:

If 8x = 4, then you can solve for x by dividing both sides by 8. Therefore, x = 4/8 or 1/2.

Then to solve 2 + 12x you simply plug in 1/2 for x.

2 + 12x

2 + 12(1/2)

2 + 6

Answer:

676

Step-by-step explanation:

First find what 48 percent of 1300 is

1300*0.48=624

Then subtract the number of females from the total number of students.

1300 student -624 females=676 males.

Hope that's clear :)

Answer:

[tex]676[/tex]

Step-by-step explanation:

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:

The correct option is (b).

Step-by-step explanation:

We are given with the factors of quadratic function. They are as follows :

(x − 7) and (x + 3)

It is required to find the zeroes of function g.

To find zeroes of function, it is required to put the factors equal to 0 i.e.

[tex](x-7)=0\\\\x=7[/tex]

and

[tex](x+3)=0\\\\x=-3[/tex]

From above calculations, we can say that the zeroes of function g are 7 and (-3). Hence, the correct option is (b).

Step-by-step explanation:

this is the answer bro or sis.

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!

Step-by-step explanation:

Answer:

m = v + 2

Step-by-step explanation:

Since Mags (m) is 2 years older than Vector (v)

You can use the equation V + 2 which is Vector's age + 2 years. Which would be equal to Mags' age.

Answer:

9 cm

Step-by-step explanation:

Volume of M= 17cm^3. Volume of N=136cm^3

Volume of N/Volume of M = k^3

136/17=8

Cube root of 8 =2

Now we know that k=2.

Height of N/2 =height of M

18/2= 9

Therefore, the height of M=9
