Answer:

16 girls in the class

14 boys in the class

Step-by-step explanation:

Because of the ratio of 7:8, I added 7+8.

7+8= 15

30 (the number of students in the class) divided by 15 (the sum of the ratio)

30/15= 2

I then multiplied 8 from the "girls" part of the ratio by 2 (the quotient of 30/15) and got 16. Then I subtracted 16 from 30 and got 14, which s the number of boys in the class.

Answer:

the length of a room is 2 m longer than its breadth .if the area of its floor is 63 sq.m.calculate the length and the breadth of the room

Length and breadth

Let the length and breadth be l + 2 and l

Now,

[tex] \large \sf \: Area = l + 2 \times l [/tex]

[tex] \large \sf \: 63 = l + 2 \times \: l[/tex]

[tex] \large \sf \: 63 = 2l + {l}^{2} [/tex]

[tex] \large \sf \: {l}^{2} + 2l - 63 = 0[/tex]

[tex] \large \sf \: {l}^{2} (9l - 7l) - 63 = 0[/tex]

[tex] \large \sf \: l(l + 9) - 7(l + 9)[/tex]

Either

[tex] \large \sf \: l = - 9[/tex]

or,

[tex] \large \sf \: l = 7[/tex]

Length can't be negative,

So,

L = 9

B = 7

7.2 or 7.20 my work is explained below!

first divide $3.00 by 5. our answer would be .6 (check: .6x5=3)

so now we know .6 is the cost of 1 ticket. so next, we would multiply .6 by 12 to get our answer. our answer would be 7.2 or 7.20.

Answer:

A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers.

Answer:

Here are the answers. Hope this helps you!

Step-by-step explanation:

11/12*9/22 = rational         (as the solution is 33/88 which is in p/q form with                                    q not equal to 0 and p and q as integers.)

√5 *8 = 8√5 = irrational

3 + √17 = irrational                               (sum of a rational and irrational     number is always irrational)

√3*√12 = √36 = 6= rational number

π - 2π = -π = irrational                                   (since π is irrational)

-3/8 + 3/5 = -15+24/40 = 9/40 = rational

√6/2  - 1/2 = 1/2*√6 - 1 * 1/2 = 1/2 (√6 - 1) = irrational      (in this case difference is irrational and the product is clearly irrational as well).

Answer:

The answer is HL which is option D.

Step-by-step explanation:

Congruent shapes have equal corresponding sides and angles.

The congruence theorem that can be used to prove  is HL

[tex]\triangle BAE \cong \triangle CAD[/tex] means that, the triangles are congruent.

From the figure, we have the following congruent sides

The above highlights mean that the theorem can be used to prove that the triangles are congruent is HL.

This is so, because the hypotenuse of both triangles are equal.

Answer: B and E

Step-by-step explanation: Trust me, this is correct

The equation of the graph representing Jenna's profit is -

y = 2.75x

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Jenna's profit for selling 38 ornaments is $104.50. Suppose Jenna keeps track of the number of sales (x) and profit (y) on a graph.

Assume that the equation of the graph representing Jenna's profit is -

y = mx + c

Then, it is a basic fact that with 0 sales, $0 profit will will be there. So, the line passes through (0, 0). Hence, the y - intercept [c] = 0. Then -

slope = [m] = (104.5)/38 = 2.75

So, the equation of line would be -

y = 2.75x

Therefore, the equation of the graph representing Jenna's profit is -

y = 2.75x
