A jar contains 21 marbles: 8 white, 3 green, and 10 red. Write the described ratio in simplest form.

A. number of white marbles to number of green marbles.

Answers

Answer:

The question you posted was a bit confusing for me, but I'm assuming that you want the simplified ratio of the number of white marbles to the number of green marbles.

The answer would be 8:3.

Step-by-step explanation:

There are 8 white marbles and 3 green marbles, so you get 8:3. And since 8 and 3 are relatively prime, no simplifying is needed.

The answer is 8:3.

Ms. Reynold's sprinkler system has 5 stations that water all parts of her front and back lawn. Each station runs for an equal amount of time. If it takes 16 minutes for the first 2 stations to water, how long does it take to water all parts of her lawn?

Answers

Answer: 40 minutes

Step-by-step explanation:

It takes 16 minutes for the first 2 stations to water their sections which means that the time taken per station is:

= 16/2

= 8 minutes per station

Ms. Reynolds has 5 stations.

Total time taken will therefore be:

= 8 * 5

= 40 minutes



A robin can fly 10 miles per hour faster than a blue jay. It takes a robin 1 1/2 hours to fly 45 miles.

How many hours will it take a blue jay to fly that same distance?

Answers

Answer: [tex]2\dfrac14\text{ hours}[/tex]

Step-by-step explanation:

Given:  It takes a robin [tex]1\dfrac12[/tex] hours to fly 45 miles.

[tex]1\dfrac12=\dfrac32[/tex]

Speed of robin= [tex]\dfrac{distance}{time}=\dfrac{45}{\dfrac32}[/tex]

[tex]\dfrac{45}{3}\times2= 15\times2= 30\text{ miles per hour}[/tex]

A robin can fly 10 miles per hour faster than a blue jay. It

Speed of Blue jay = Speed of robin - 10 miles per hour

= 30 miles per hour - 10 miles per hour

= 20 miles per hour

Time taken to cover 45 miles = [tex]\dfrac{45}{20}=\dfrac{9}{4}=2\dfrac14\text{ hours}[/tex]

Hence, it will take [tex]2\dfrac14\text{ hours}[/tex]  by a blue jay to fly that same distance.

The number of red cells are 4 and the number of blue cells are 8. Then the correct option is C.

What are ratio and proportion?

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

In the grids, there are 12 square box.

Let R be the red and B be the blue.

R + B = 12   ...1

R / B = 1/2  ...2

By solving equation 1 and 2, we have

R + 2R = 12

      3R = 12

        R = 4

Then  

4 + B = 12

     B = 8

Then the correct option is C.

During their last game, the Miami Dolphins scored ͸ times for a total score of ͵Ͳ points. They scored ͹ points for each touchdown and ͵ points for each field goal. Write and solve the systems of equations to find the total touchdowns and field goals scored.

Answers

Answer:

The Miami Dolphins had 3 touchdowns and 3 field goals.

Step-by-step explanation:

It is given that During their last game, the Miami Dolphins scored 6 times, for a total score of 30 points. They scored 7 points for each touchdown and 3 points for each field goal.

We need to write and solve the system of equations to find the total touchdowns and field goals scored.

Let x represents the number of touchdowns.

Let y be the number of field goals.

It is given that the Miami Dolphins scored 6 times

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

[tex]x=6-y[/tex]....(1)

They scored 7 points for each touchdown and 3 points for each field goal.

The total score is 30 points:

[tex]7x+3y=30[/tex] ...(2)

Put the value of x from equation (1) into equation (2).

[tex]7( 6-y)+3y=30[/tex]

[tex]42-7y+3y=30[/tex]

[tex]-4y=30-42[/tex]

[tex]-4y=-12[/tex]

[tex]y=3[/tex]

Put y = 3 in equation 1.

[tex]x=6-3[/tex]

[tex]x=3[/tex]

Hence, the Miami Dolphins had 3 touchdowns and 3 field goals.

Find two consecutive even integers such that the sum of the smaller and 3 times the larger is 330
I am so stuck please any one help

Answers

Answer:

The 2 numbers = 81 and 83

Step-by-step explanation:

As, one number = x

The other, because it's an even number and consecutive = x + 2

So the larger numbef here is x + 2

And they are saying 3 times x + 2 plus x = 330

So let's solve!

3 times x + 2 = 3(x+2) = 3x + 6

So we will add it to x = (3x + 6) +(x) = 4x + 6

So they are saying the sum of them will be 330

So, 4x + 6 = 330

4x = 330 - 6

4x = 324

x = 324/4

x = 81

So x is the first number = 81

And the second is x + 2 = 81 + 2 = 83

So the 2 numbers are 81, 83

Lets check!

3 times the bigger number = 83 x 3 = 249

We will add it to 81 and we will get 330

So, 249 + 81 = 330

So the answer is right

Step-by-step explanation:

(9y + 7)° + (7y - 19)° = 180° (interior angles in the same side of transversal)

(9y + 7 + 7y - 19)° = 180°

(16y - 12)° = 180°

16y - 12 = 180

16y = 180 + 12

16y = 192

y = 192/16

y = 12

Answer:

9y+7=7y-19

7+19=7y-9y

the 4 angles of heptagon equal and each of other 3 is 20° greater the first 4.Find the angles​

Answers

Answer:

interior angle of a heptagon = 900 degrees

900 = 4x + (3x + 60)

840 = 7x

840/7 = 120

X = 120

120 X 4 = 480

120 X 3 = 360

480 + 360 + 60 = 900

4 angles = 120 degrees each

3 angles = 140 degrees each
