Answer:

Total number of students = 200

The number of girls  = 90

Step-by-step explanation:

Girls = 45%

Boy = (100 - 45)% = 55%

Let the total students = x

Number of boys = 110

55% of x = 110

 [tex]\frac{55}{100}*x = 110\\\\ x = 110*\frac{100}{55}\\\\ x = 10 * \frac{100}{5}\\\\[/tex]

  x = 2 * 100

  x = 200 students

Girls = 45% of x

       [tex]= \frac{45}{100}*200[/tex]

        = 45 * 2

Girls = 90

Answer:

The equation of the parabola  ( y +3)² = 4 ( x-3)

Step-by-step explanation:

Step(i):-

we know that the focus of the parabola (h + a , k ) and directrix is   x = h - a

Given

 focus of the parabola (h + a , k ) = ( 4, -3 )

  Equating                h + a =4 ..(i)

                              and k =-3

Given directrix is   x = 2

                          h - a =2 ..(ii)

Adding (i) and (ii) equations , we get

                   h + a + h-a = 4+2

                      2 h = 6

                         h =3

   substitute h=3 in equation (i)

                h + a =4

               3 + a =4

                  a = 1

The length of Latus rectum 4a = 4(1) =4

Step(ii):-

The vertex ( h, k) = ( 3 , -3) and a = 1>0

Given directrix is x = h - a = 2 so the parabola axis is lie on X- axis and symmetric about x-axis

The equation of the parabola

( y - k )² = 4 a ( x - h )

( y - (-3))²= 4(1) ( x - 3 )

The equation of the parabola  ( y +3)² = 4 ( x-3)

Answer:

66.25 fluid ounce

Step-by-step explanation:

Given that :

Capacity of original container = 53 fluid ounces

Percentage addition of new container = 25%

Capacity of new container :

Capacity of original container * ( 1 + percentage addition)

53 * ( 1 + 0.25)

53 * (1.25)

= 66.25 fluid ounce

Complete question :

A dog needs 4/3 liters of water for 2/5 of a day. How many liters of water does the dog need for an entire day?

Answer:

10/3 litres

Step-by-step explanation:

Given that:

Amount of water needed for 2/5 of a day = 4/3 litres ;

An entire day = 1/ 1 of a day

Hence, If;

2/5 = 4/3 litres of water

1/1 = x

Cross multiply ;

(2/5)x = 4/3

2x /5 = 4/ 3

2x * 3 = 5 * 4

6x = 20

x = 20 /6

x = 10 /3 litres

Answer:

$97.20

Step-by-step explanation:

you make the 8% into a decimal by moving the decimal to places to the left.

8%=0.08, Then you multiply that by the whole number of 90 dollars.

0.08 x 90 = $97.20

Total cost of the jacket with sales tax is given by the equation A = $ 97.20

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total cost of the jacket with the sales tax be A

Now , the equation will be

The cost of the jacket = $ 90

The sales tax percentage = 8 %

So , the sales tax amount = ( 8 / 100 ) x cost of the jacket

Substituting the values in the equation , we get

The sales tax amount = 0.08 x 90

The sales tax amount = $ 7.20

Now , the total cost of the jacket with the sales tax = cost of the jacket + sales tax amount

Substituting the values in the equation , we get

The total cost of the jacket with the sales tax A = 90 + 7.20

The total cost of the jacket with the sales tax A = $ 97.20

Hence , the total cost is $ 97.20

Answers:

===========================================

Explanation:

Triangle GJI and triangle PKH are similar triangles. The order of the letters is important because it tells us how the angles pair up.

The first letter of GJI is G, while the first letter of PKH is P. This means angles G and P pair up. They are congruent pair because similar triangles have congruent corresponding angles.

So,

G+P = 50

G+G = 50 .... plug in G = P

2G = 50

G = 50/2

G = 25

Both angle G and angle P are 25 degrees

Use angle I = 48 to help find angle J

G+J+I = 180

25+J+48 = 180

J+73 = 180

J = 180-73

J = 107

Angle J is 107 degrees

Since J and K are the second letters of GJI and PKH respectively, this means angle J = angle K = 107

Since I and H are the third letters of GJI and PKH respectively, we know that angle I = angle H = 48

Answer:

11:29.

Step-by-step explanation:

10:47 - 11:00 is 13 minutes, which leaves 29 minutes. So then you add that to 11:00, 11:29.

Answer:11:29

Step-by-step explanation:

If Doug starts at 10:47 and sweeps for 42 minutes

First you add 42 minutes to the 47.

Remember there are 60 minutes in an hour.

So do 47+42=89

Next do 89-60 (because there are 60 minutes in an hour)

You get 29 minutes.

Add one to the 10

That makes 11:29

Answer:

number 1. answer is  5

number 2. answer is  2 1/2

number 3. answer is 9/16

number 4. answer is 45.7

number 5. answer is 18.7

Answer:

1. 5 miles

2. 5 4/12 cups

3. 9/16 gallons

4. 45.7 km/h

5. 18.7 m/h

Step-by-step explanation:

For the first one, she jogs 1/2 miles in 1/10 of an hour. So to get an hour you can do the reciprocal of 1/10 to get 1

1/10 * 10/1 = 1 hour

Now you have to do that to the miles as well.

1/2 * 10/1

1 * 10 = 10

2 * 1 = 2

10/2

5 miles

So she jogged 5 miles in 1 hour

For the second one, 8 3/4 cups of milk for 3 1/3 cups of cereal. You need 1 cup though.

So to find 1 cup you have to get a common denominator first.

1/3

3/4

A common factor is 12. multiply 4 for both the top and the bottom for 1/3 and 3 to top and bottom for 3/4. What's done to the top must be done to the bottom as well.

1/3 *4/4 = 4/12

3/4 * 3/3 = 9/12

8 4/12 and 3 9/12 is what you have now.

You only need 1 cup so you can subtract 2 9/12 to both.

8 4/12 - 2 9/12 = 5 4/12

3 9/12 - 2 9/12 = 1

So 1 cup of oatmeal uses 5 4/12 cups of milk.

For the third one, 3/16 gallons of water for 1/3 feet of garden.

You need to find that for 1 foot so it be similar to the first one.

Use reciprocal on 1/3 to get that 1 foot you need.

1/3 * 3/1 = 1

What you do to one you have to do to the other.

3/16 * 3/1 = 9/16

You can't simplify it so that's its simplest form.

S 1 foot of garden uses 9/16 gallons of water.

Numero four. This one seems hard but really all you have to do is divide km by h.

822.6 km/ 18 h

45.7 km/h

Last one, once again all you have to do is divide m by h to get m/h.

768.57m/41.1h

18.7 m/h

And thats it! I hope this helps you and if you ever need any more help, don't be afraid to reach out.
