In a school, the ratio of the number of boys to the number of girls in a school is 7 : 5 - if there are 600 students in the school, how many girls are there?
How many students does each unit represent?

Answer: 4,187 in3

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a sphere: 4/3 π (diameter /2)^3

Replacing with the values given;

V = 4/3 (3.14) (20/2)^3 = 4/3 (3.14) 10^3 =4,187 in3

The volume of the sphere is 4,187 cubic inches.

Feel free to ask for more if needed or if you did not understand something.

i think 10

Step-by-step explanation:

there is 8 pints in 1 gallon and 2 pints in 1 quart so that means in 23 quarts theres 46 pints and in 7 gallons there is 56 so 56-46 is 10 if that is what the question is asking lmk if the question is wrong

Answer:

she was a woman.

Answer:

(3,1)

Step-by-step explanation:

5x + 3y = 18

2x + 3y = 9

So we can use elimination here to solve this system of equations by multiplying the second equation by -1

Now we have:

5x + 3y = 18

-2x - 3y = -9

Now we add straight down and combine like terms

The y terms cancel and we are left with 3x = 9, dividing both side by 3 we get x = 3

Now we can plug this x value into one of the original equations to solve for our y value

I will use the first equation: 5(3) + 3y = 18 → condensing the terms we get  15 + 3y = 18 → subtracting the 15 from both sides we get 3y = 3 → dividing both sides by 3 we get y = 1

The solution to this system of equations is (3, 1)

A!

Step-by-step explanation:

Ik it's been like a month since you asked the question, but domain is from the lowest x point to the highest x point. So, from the farthest left to the farthest right basically. Range is lowest y point to highest y point.

Answer:

here is how

Step-by-step explanation:

the x (6) is the horixontal ways on the co-ordinate plane. you go right until you reach the six. the y (4) is vertical. take the point that is on 6,0. and move it up until you see it on 4. now you have the coordinates 6,4.

Answer:

I THINK THE SLANT IS 14M (sorry if i'm wrong)

Step-by-step explanation:

Answer:

[tex]P(X<50)=P(\frac{X-\mu}{\sigma}<\frac{50-\mu}{\sigma})=P(Z<\frac{50-60.5}{7.2})=P(z<-1.46)[/tex]

And we can find the probability using the normal standard distribution or excel and we got:

[tex]P(z<-1.46)=0.0721[/tex]

Step-by-step explanation:

Let X the random variable that represent the shelf life of packed food of a population, and for this case we know the distribution for X is given by:

[tex]X \sim N(60.5,7.2)[/tex]  

Where [tex]\mu=60.5[/tex] and [tex]\sigma=7.2[/tex]

We are interested on this probability

[tex]P(X<50)[/tex]

For this case we can solve this problem with the z score formula:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

If we apply this formula to our probability we got this:

[tex]P(X<50)=P(\frac{X-\mu}{\sigma}<\frac{50-\mu}{\sigma})=P(Z<\frac{50-60.5}{7.2})=P(z<-1.46)[/tex]

And we can find the probability using the normal standard distribution or excel and we got:

[tex]P(z<-1.46)=0.0721[/tex]

Step-by-step explanation:

Answer:

14.4 m

Step-by-step explanation:

let the height of the tower from line of sight be x, then

tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{30}[/tex] ( multiply both sides by 30 )

30 × tan23° = x , thus

x ≈ 12.7 m

Total height of tower = 12.7 + 1.7 = 14.4 m ( to the nearest tenth )

Answer:

x=2

Step-by-step explanation:

triangle area is 1/2BH

1/2(4x)=4

2x=4

x=2 units

Answer:

Missing side = 2

X= 2

Have given details if x was only base of the side triangle

This is in order to find a completely new triangle with just the height and in order to find and combine 1 given area say if just the right side in your diagram was 4 and we had to find the other triangle. This is only done on scale or 1 given measure or angle for the right side triangle. We was not given this but proved a 0.3 scale.

Area of other triangle =2.66^2

2.66+4 combined = 6.66^2

Step-by-step explanation:

We find a square height is also 4

We also know a right angle triangles height can be found using either 1/2 base or 1/2 height.

So this can mean the height is and stays 4 and the base is 2.

As 1/2  4 height = 2 height

2 unit height x 2 unit base = 4

Therefore, the first triangle slant is the same.

4sq +2sq = c^2

√16+√4 = √20

c^2 = √20 = 4.47     = 4.472135955

c = 4.47 slant

Given a=4 and c=4.47,

b = 1.99522

∠α = 63.49° = 63°29'23"

∠β = 26.51° = 26°30'37"

h = 1.78543

We cna tell now that the triangle is 0.333 smaller so the measurements

Show 2/3 of 2 = 1.333 being the base across

using this as Area we find 1.333 x 2 =  2.666

(1/2 h^b of 4) =2

We can prove with the angles

63 +27 degree or

a^2+b^2 = c^2

1.333^2 + 4^2

= √1.776889+√ 16 = √ 17.776889

c^2 = 4.21626481616

c= 4.22 slant left side  (nb right side on attachment)

Angle ∠ A = α = 71.478° = 71°28'39″

Angle ∠ B = β = 63.53° = 63°31'48″

Angle ∠ C = γ = 44.992° = 44°59'33″

We see 63 angle on right lower side of attachment picture in reflection and can prove x = 3.333

But on your diagram base x = 2

What i have done is enlarged x by 0.3 and proven  how to find x if x was just one side of the triangle's height.

The triangles even though reflected are identical.

Other info is proven through finding ha and hb heights.

We confirm 4.001 is the hc height of your diagram.

Height: ha = 2.984

Height: hb = 3.16

Height: hc = 4.001

Answer:

6 cm ^2

Step-by-step explanation:

Answer:

The surface area is 6 cm².

Step-by-step explanation:

Given that a cube has side lengths all the same. Then you have to use surface area formula, S.A = 2(length×width) + 2(length×height) + 2(width×height) :

Let length = 1cm,

Let width = 1cm,

Let height = 1cm,

[tex]s.a = 2(1 \times 1) + 2(1 \times 1) + 2(1 \times 1)[/tex]

[tex]s.a = 2 + 2 + 2[/tex]

[tex]s.a = 6 \: {cm}^{2} [/tex]
