In Fluorescent higher secondary school there are 53 students in class 8. If number of boys is 3 morethan that of number of girls find.
a. Equation representing the number os students.
b. The number of Boys and Girls.​

Answers

Answer 1

Answer:

a. 3g + g = 53

b. 40 boys and 13 girls

Step-by-step Explanation:

(3g = number of boys)

(g = number of girls)

3g + g =53

4g = 53

g = 13.2

53 - 13.2 = 39.8 (boys)

we round to the nearest tenth on both

girls 13.2---13

boys 39.8---40

Krysta is looking for a job cutting hair. One option is self-employment at The Richmond Salon, where she would pay $474 per month to rent a station and keep all of her earnings. Another option is to work at a franchise, where she would just have to pay the salon $6 for every haircut. If she performed a certain number of haircuts every month, the amount paid to either salon would be the same. How many haircuts would that be? How much would Krysta pay?

Answers

Answer:

79 haircuts and $474

Step-by-step explanation:

The computation is shown below:

Given that

she would have to pay $474 per month

And $6 for every haircut

So, the number of haircuts would be

= $474 ÷ $6

= 79 haircuts

The amount that she have to pay is $474

The raito of chocolate covered carmels to choclate corvered cherries in my vault is 5 to 2 if i have 84 choclate covereds cherries how many choclate covered caramels do i have

Answers

Answer: 1 have 210   chocolate covered caramels

Step-by-step explanation:

step 1

The  ratio  of chocolate covered caramels to chocolate covered cherries in my vault is 5 to 2 which can also be written as 5:2

But the number of chocolate covered cherries =84

Total ratio is given as 5+2 = 7

Step 2

such that the total number of chocolate i had  would be gotten from

Ratio of chocolate covered cherries/ total ratio x Total chocolates = Number of chocolate covered cherries. Let X = Total number of chocolates

2/7 x X = 84

x= 84 x 7 / 2 =294

Therefore The number of chocolate covered caramels= ratio of chocolate covered caramels/ total ratio x Total chocolates =

5/7 X 294= 210

The piecewise function h(x) is shown on the graph.

On a coordinate plane, a piecewise function has 2 lines. The first line has a closed circle at (negative 4, negative 4) and goes up to an open circle at (negative 1, 2). The second line has a closed circle at (negative 1, 3), continues horizontally to (1, 3), and then goes down to a closed circle at (4, 0).
What is the value of h(3)?

–2
–1

2

Answers

Step-by-step explanation/Answer:

The value for h(3) is 1.

Coordinate (3,1)

The value on h(3) is located in the last part of the piecewise function, which starts at (1,3) until (4,0). To know the exact image of h(3), we can find the function that belongs to that piece of line, and then calculated the asked value.

So, to calculate the equation, we first have to find the slope with its definition, and then we'll use the point-slope formula to find the equation:

Therefore, the coordinates is (3,1), that is, the value for h(3) is 1.

A teacher purchased 20 calculators and 10 measuring tapes for her class and paid $495. Later, she realized that she didn't order enough supplies. She placed another order of 8 of the same calculators and 1 more of the same measure tape and paid $178.50.The system represents the situation

`20c+10m=495`

`8c+1m=178.50`

Find the cost of one calculator and the cost of one measure tape using one of our methods of solving systems.

Answers

Answer:

Equations are

20c + 10m = 495..............(1)

8c + 1m = 178.5.................(2)

Now ,  equation (2) * 10 = 80c + 10m = 1785...........(3)

So, Eq. (3) -  Eq(1) =

80c + 10m - 20c - 10m = 1785 - 495

60c = 1290

c= 21.5

********************************************************

Now place the value of c in Eq (2)

So , m =6.5

[tex]y=-\frac{1}{5}x+\frac{6}{5}[/tex]

Step-by-step explanation:

Let's solve for x.

[tex]x+5y=6[/tex]

Step 1: Add -5y to both sides.

[tex]x+5y+-5y=6+-5y[/tex]

[tex]x=-5y+6[/tex]

Answer:

[tex]x=-5y+6[/tex]

Let's solve for y.

[tex]x+5y=6[/tex]

Step 1: Add -x to both sides.

[tex]x+5y+-x=6+-x[/tex]

[tex]5y=-x+6[/tex]

"An airplane ends up 540 miles and 20 degrees north of east from its departure point. If there was a steady wind of 30 mph from the northwest during the entire flight, then find the magnitude and direction that the plane would have gone if there had been no wind".

Answers

Answer:

vr = [tex]540[/tex]

vp = 486.22 j + 205.9 j

Theta  [tex]= 22.95[/tex]

Step-by-step explanation:

The resultant velocity vr = vp + vw

vp = vector velocity of plane and

vw = vector velocity of wind

vr = vector resultant velocity

in one hour the plane travels 540 miles and hence the speed is 540 mph

Hence vr = [tex]540[/tex]

vp = 486.22 j + 205.9 j

Theta

[tex]= tan^{-1}\frac{205.9}{486.22} \\= 22.95[/tex]
