The ratio of the number of girls to the number of boys in a chess club is 3 to 2. There are 14 boys in the
chess club. What is the number of girls in the chess club?

Answer:

4(2x+4)

for example, if 5 were the length of a side you'd do 4(5). 4 because theres 4 sides and the formula for P is P= l+l+w+w OR P=2l+2w

Answer:

For this question, subtract 5 on both sides to get [tex]\frac{m}{3}[/tex]=7. Then, multiply 3 on both sides to get m=21.

Answer:

M=21

Hope this helps, and happy valentines day :D

Answer:

1,413,720

Step-by-step explanation:

Total number of characters = letters + numbers

= 26 + 10

= 36.

So total number of possible codes

= 36P4

=  36!/ (36-4)!

= 36*35*34*33

= 1413720

Answer:

9 pitchers

Step-by-step explanation:

Given

Cylinder 1:

[tex]Radius = r[/tex]

[tex]Height = 9[/tex]

Cylinder 2:

[tex]Radius = 3r[/tex]

[tex]Height = 9[/tex]

Required

How many pitchers' cylinder 2 can fill

First, we calculate the volume of both cylinders

Volume is calculated as:

[tex]Volume = \pi r^2h[/tex]

For A:

[tex]V_A = \pi r^2*9[/tex]

[tex]V_A = 9\pi r^2[/tex]

For B:

[tex]V_B = \pi (3r)^2 * 9[/tex]

[tex]V_B = \pi *9r^2 * 9[/tex]

[tex]V_B = 9* 9\pi r^2[/tex]

In (a): [tex]V_A = 9\pi r^2[/tex]

So, we have ve:

[tex]V_B = 9*V_A[/tex]

[tex]V_B = 9V_A[/tex]

If the first cylinder can fill 1, then the second can fill 9 pitchers

Answer:

11.2

Step-by-step explanation:

Given that the two triangles share an angle (bottom left), and since the sides opposite this angle are parallel, we can conclude that the triangles are similar.

Put one side length over another and equak to the corresponding side lengths of the other triangle:

28/15=?/6

?=6(28/15)=11.2

Answer:

the answer is C, here is an app or website that u could use for math :)

Answer:

4.75 if you don't have to convert it to US dollars.

Step-by-step explanation:

1. The question is asking how much is the cost of each sachet.

2. One given fact is that 6 pieces of a sachet cost 28.50.

3. Division.

4. Can't tell if you're asking for the equation but 28.50 / 6 = 4.75. Or do 28.50 / 6 = c

5. 4.75.

If they're asking you to convert it into united states dollars:

1. It's asking how much is the cost of each sachet.

2. One given fact is that 6 pieces of a sachet cost 28.50.

3. Division.

4. Can't tell if you're asking for the equation but 28.50 / 49 = 0.58163265306 (0.59 if you round it) Or do 28.50 / 49 = c

5. 0.59.

Tbh I just used g00gle and converted philiphine pesos to USD (United States) dollars, if it's not right, then sorry-

[tex] {6x}^{2} + -15x + 18x -45[/tex]

hope that helped:)

Step-by-step explanation:

=(3x+9)(2x-5)

=3x(2x-5)+9(2x-5)

=6x²-15x+18x-45

=6x²+3x-45

hope it helps.

Answer:

(n + 2)² = 12

Step-by-step explanation:

[tex] {n}^{2} + 4n - 8 = 0 \\ {n}^{2} + 4n = 8 \\ {n}^{2} + 4n + 4 = 8 + 4 \\ {(n + 2)}^{2} = 12[/tex]

Answer:

Step-by-step explanation:

2y+4=10

we will subtract 4 from both sides

2y=10-4

2y=6

y=3

Answer:

3is your answer

2y+4=10

2y=10-4

y=6/2=3

Answer:

189.3 cm^2

Step-by-step explanation:

split into a rectangle and a semi-circle

rectangle=LxW=10x15=150 cm^2

radius (r)=1/2 diameter=5 cm

semi-circle=1/2(pi)r^2=1/2(3.14)(5^2)=39.25 cm^2

150+39.25=189.25 cm^2

Answer:

y-5=1/6(x-1)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(4-5)/(-5-1)=-1/-6=1/6

slope is 1/6

y-y1=m(x-x1)

y-5=1/6(x-1)

Answer:

the answer is number 9 m1

Answer:

D. no solution

Step-by-step explanation:

substitute y = 2x + 3 in

2y = 4x + 10

gives 2(2x+3) = 4x + 10

4x - 4x = 10 - 6

therefore the equation has no solution

Answer:

1/3

Step-by-step explanation:

There are 9 total outcomes, and 3 are favorable, or are two of the same color in a row. 3/9 simplifies to 1/3. Hope this helps!

Answer:

If an angle of one triangle is congruent to the corresponding angle of another triangle and the lengths of the sides including these angles are in proportion, the triangles are similar. the remaining sets of angles will be congruent and the remaining corresponding sides will be in proportion.

Answer:

20%

Step-by-step explanation:

im not really good at percentages but from what i know you first make it a fraction by adding all the numbers together to get 55(denominator). then for the numerator you take the section that they want(11). 11/55 is equal to 20/100(divide 100 by 55 and multiply the quotient by 11 to get 20). 20/100 is 20%. hope this kinda helps.

Answer:

The triangle is 1, since 10 - 1 is 9.

Step-by-step explanation:

Answer:

14.4

Step-by-step explanation:

2.5 divided by 6 is 2.4

2.4 x 6 = 14.4

Answer:

3/14

Step-by-step explanation:

In order to divide fractions, you'll have to find the recriprocal of 2/5. That is 5/2. So do 1/7 x 5/2 = 5/14.

So now find 5/14 - 1/7.

1/7 converted to a denominator of 14 is 2/14.

So we have 5/14-2/14 = 3/14. That is your answer.

The first thing that we should do is turn this into a mathematical formula.

[tex]\frac{1}{7} / (\frac{2}{5} -\frac{1}{7} ) = \frac{1}{7} /(\frac{9}{35} )[/tex] .

This is more generally written as

[tex]7(\frac{9}{35}) = \frac{9}{5}[/tex]

So, our answer is 9/5 or 1.8
