the ratio of number of girls and boys in a class is 4:3 if there are 20 girls find the number of boys. plz do it in process​

Answers

Answer 1

Answer:

15 boys

Step-by-step explanation:

Whatever number one side of the ratio is multiplied by, the other side has to be multiplied by that same number. So, we have to find the number that 4 is multiplied by to get 20. We can represent this as an equation, where the unknown number is x:

4x = 20

Divide both sides of the equation by 4 to find the value of x:

x = 5

4 was multiplied by 5 to get 20.

To find the number of boys, multiply 3 by 5:

3 * 5 = 15

If there are 20 girls, there will be 15 boys.

Answers

Answer:

It's the third one down for both of them.

Step-by-step explanation:

1. first count the spaces from each intersection, starting with down. #1 has a slope of 2/3. Since it's leaning to the left, it's a negative. The only one with -2/3 is the third option down.

2. Again, look at the slope. this one is 2/1 (or just 2), and is leaning to the left, so is negative. Since there are multiple with -2 as the slope, we then look at the y-intercept. It's -1. The only answer that lines up perfectly with what we have is the third one down.

Step-by-step explanation:

[tex]-4x+7=23[/tex]

[tex]-4x=16[/tex]

[tex]x=-4[/tex]

Answer:

x=-4

Step-by-step explanation:

2x+7−6x=23

Step 1: Simplify both sides of the equation.

2x+7−6x=23

2x+7+−6x=23

(2x+−6x)+(7)=23(Combine Like Terms)

−4x+7=23

−4x+7=23

Step 2: Subtract 7 from both sides.

−4x+7−7=23−7

−4x=16

Step 3: Divide both sides by -4.

Your team is in charge of games at the Amusement Park. One of the games involves a robotic arm that randomly grabs a stuffed animal out of a large bin. You need to set up the game so that the probability of a customer’s grabbing a teddy bear is exactly 1/2


a. how would you set up the bin? Explain.


B. What if you returned to check on the bin and found that there are 4 teddy bears left and 12 other animals? What could you add to or remove from the bin to return the probability of selecting a teddy bear to 1/2?

Answers

Answer:

a. I would put 20 stuffed animals in the bin, out of which 10 would be teddy bears.

So that the probability is 10/20 = 1/2

b. I could remove 8 other animals from 12 to have 4. So that the total number of stuffed animals is 8. 4/8 = 1/2

Step-by-step explanation:

a. Probability =

number of required outcomes / number of possible outcomes

If in the bin there are 10 teddy bears out of 20 stuffed animals,

Then the probability of picking a teddy bear = 10/20 = 1/2.

b. If on returning, there are 4 teddy bears and 12 other animals, I could simply remove 8 of the other animals to have 4 other animals and a total of 8 stuffed animals.

Probability = 4/8 = 1/2

∆GHI is an isosceles triangle with a vertex angle H If the m∠H=80°, then find the m∠I.

Answers

Answer:

m∠I = 50 degrees

Step-by-step explanation:

Mathematically, the base angles of an isosceles triangle are equal

So in this case, since H is a vertex;

m∠I + m∠H + m∠G = 180

m∠I = m∠G = x

2x + 80 = 180

2x = 180-80

2x = 100

x = 100/2

x = 50

The ratio of boys to girls in a class is 3:4. There are 35 students in the class. How many students are boys?

Answers

Answer:

15 boys and 20 girls

Step-by-step explanation:

1. Since we cant simplify 3:4 we will leave it just like that.

2. 3x+4x=35

3. We add them both to give us 7x=35

4. We divide by 7 to get x by itself which results in 35/7=5.

x=5

5. Now we found x we can create 2 seperate soulutions:

3(5)=

and 4(5)=

Therefore there are 15 boys and 20 girls in the class. This makes sense because 15/20 reduced is 3 over 4.

b) Set up an equation using the variable you defined in (a):

The equation is :

3f - 2 = 13

c) Solve your equation & Check. How many fish does Ms. Montesinos have?

Ms. Montesinos has 5 fishes

Step-by-step explanation:

Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has. How many fish does Ms. Montesinos have in her tank?

a) Write a let statement below to define your variable(s):

Let the number of fishes Ms. Montesinos has be represented by = f

b) Set up an equation using the variable you defined in (a):

We are told in the question:

Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has.

Therefore,

3× f - 2 = 11 + 2

The equation is :

3f - 2 = 13

c) Solve your equation & Check. How many fish does Ms. Montesinos have?

Solving the above equation:

3f - 2 = 13

3f = 13 + 2

3f = 15

Divide both sides by 3

3f/3 = 15/3

f = 5

Hence, Ms. Montesinos has 5 fishes
