The ratio of boys to girls at a movie is 4:5. If there are 15 girls, how many boys are at the movie?

Answers

Answer 1

Answer:

There are 12 boys at the movie.

Step-by-step explanation:

Key skills needed in order to solve: Proportions, Ratios, and Multiplication

1) The ratio is 4 boys : 5 girls --> It can be written as a fraction --> 4/5

2) If there are 15 girls, we need to find the number of boys. let's say x is the number of boys when there are 15 girls. The ratio would then be x/15

3) Make a proportion --> [tex]\frac{4}{5}[/tex] = [tex]\frac{x}{15}[/tex]

You have to cross multiply here. You do the first fraction's numerator times the second fraction's denominator, and the first fraction's denominator times the second fraction's numerator.

4) This means you have to do: 4(15) = 5(x)

5) Multiply it out --> 60=5x

6) Divide by 5 and you will get x=12

Therefore there are 12 boys at the movie.

Hope you understand and have a nice day!! :D

The value of the given division 469.4 ÷ 62 will be 7.57.

What is the arithmetic operation?

In mathematics, the arithmetic operation has four main operators such as addition, subtraction, multiplication, and division.

The symbol of + represents addition.

The symbol of - represents subtraction

The symbol of × represents multiplication

The symbol of ÷  represents division.

Given the division,

469.4 ÷ 62

⇒ 7.570967742

Rounded to the nearest tenth decimal place

⇒7.57

Hence "The resultant of the 469.4 ÷ 62 is 7.57 ".

15 because 15*10=150

Answer:

[tex]x = 1500[/tex]

Step-by-step explanation:

[tex] \frac{x}{10} = 150[/tex]

Move 10 to multiply 150.

[tex]x = 150 \times 10 \\ x = 1500[/tex]

Answer Check

Substitute x = 1500 in the equation.

[tex] \frac{1500}{10} = 150 \\ 150 = 150[/tex]

The equation is true for x = 1500.

Therefore, the answer is x = 1500

Answer:

[tex]\boxed{\pink{\bf Yes \ \angle L = \angle O . }}[/tex]

Step-by-step explanation:

A figure is given to us in which ML = MO . And we have to Prove ∆ MLN [tex]\cong[/tex] ∆ MON .

Hence here , in ∆ MLN & ∆ MON ,

ML = MO ( given )LMN = MON ( Given ) MN = MN ( Common)

Hence by SAS congruence condition

[tex]\boxed{\red{\bf \triangle MLN \cong \triangle MON}}[/tex]

____________________________________

(ii) Yes ∠ L = ∠ O will be equal to each other .( by cpctc )

Extra Information :-

The congruence conditions for two ∆s are :-

1) SAS ( Side Angle Side )

→ Two triangles are said to be congruent by SAS if two respective sides of the two triangles and the included angle between two sides are equal.

2) AAS ( Angle Angle Side )

→ Two triangles are said to be congruent by AAS if two angles and one side of triangle is congruent to other two angles and one side of the triangle .

3) SSS ( Side Side Side )

→ Two triangles are said to be congruent by SAS if all the three sides of one triangle is equal to three sides of the other triangle.

4) RHS ( Right Hypotenuse Side )

→ In two right-angled triangles, if the length of the hypotenuse and one side of one triangle, is equal to the length of the hypotenuse and corresponding side of the other triangle, then the two triangles are congruent.

Step-by-step explanation:

✔️The figure given is a ¼ circle

Radius is given as = 7 cm

✔️Area = ¼(πr²)

Plug in the value of r

Area = ¼(π*7²)

Area = ¼(π*49)

Area = 38.5 cm² (nearest tenth)

✔️Perimeter = ¼(2πr) + 2r

Plug in the value of r

Perimeter = ¼(2*π*7) + 2(7)

Answer: A

Step-by-step explanation:

In this equation, the largest exponent is odd, so the two ends are going in different directions. Since the leading coefficient is positive, the left side is going down, while the right side is going up.

As y approaches negative infinity (goes down), x approaches negative infinity (goes left).

Simplified: as the y value decreases, the x value decreases.

As y approaches infinity (goes up), x approaches infinity (goes right).

Simplified: as the y value increases, the x value increases.

Step-by-step explanation:

Consider the provided exponent.

The given exponent is [tex]5^{-15}[/tex].

We need to write it using a positive exponent.

So, use the property: [tex]a^{-m}=\dfrac{1}{a^m}[/tex]

By using the above property we can rewrite the given exponent as:

[tex]5^{-15}=\dfrac{1}{5^{15}}[/tex]

Hence, the required answer is [tex]\dfrac{1}{5^{15}}[/tex].

The ratio of boys to girls in Ms. Reedus's classroom is 2 to 3. There are 18 girls in the classroom. What is the total number of students in Ms. Reedus's class?

Answers

Answer: The final answer is 30.

Step-by-step explanation: The question says the ratio is 2 boys : 3 girls. There are 18 girls. Well, how did you get from 3 to 18? You multiply by 6. But whatever you do to the denominator you have to do with the numerator. So, multiply 2 and 6. That gives you 12 boys and 18 girls. Adding 12 and 18 gives you 30. Therefore, there are 30 students in the whole class.
