A bag contains 21 red marbles, 24 green marbles, and 21 blue marbles. You choose a marble at random
from the bag. What color marble will you most likely choose?

Answers

Given:

A bag contains 21 red marbles, 24 green marbles, and 21 blue marbles.

To find:

What color marble will you most likely choose if you choose a marble at random from the bag.

Solution:

We have,

Number of red marbles = 21

Number of green marbles = 24

Number of blue marbles = 21

Total number of marbles = 21+24+21

= 66

Now,

[tex]P(Red)=\dfrac{21}{66}[/tex]

[tex]P(Green)=\dfrac{24}{66}[/tex]

[tex]P(Blue)=\dfrac{21}{66}[/tex]

The number of green marbles is largest. So, the probability of getting a green marble is largest.

Therefore, you will most likely choose green marble.

for every 3 hours of ballet practice, Danielle drinks 2 cups of water. How much will she drink during 7.5 hours of practice?

Answers

Answer:

5 cups of water

Step-by-step explanation:

well if we take this and turn it into a ratio, we know the base is 3hrs/2cups

so if we want to find 7.5hrs/x then we just multiply the two fractions and see what we get. so 7.5 divided by 3 is equal to 2.5

so we take the amount of water she drinks in 3hrs which is 2cups of water and we multiply that by 2.5 leaving us with Danielle drinking 5 cups of water in 7.5 hours of ballet practice.

hope this helps if it did please leave a like, rate, and give me the brainliest is possible!

have a great day!

I would assume it would be 4.5 cups

A car is traveling at a steady speed. It travels 2 1/3 miles in 3 1/2 minutes. How far will it travel in 25 minutes? In 1 hour?

Answers

Answer:

https://i.pinimg.com/originals/50/3f/9a/503f9a49a2faa03f7db90f090eea6bff.gif

Step-by-step explanation:

Answer:

Given:

A car travels 2 1/3 miles in 3 1/2 minutes.

We need to find the distance travelled in 25 minutes, in 1 hour.

So, 2 1/3= 7/3 and 3 1/2 = 7/2

Let's convert them into decimals by dividing them completely.

So, we will get 2.33 miles and 3.5 minutes.

So now we have that 2.33 miles are covered in 3.5 minutes.

Now we need to know the distance covered in 1 minute.

So, 2.33/3.5=0.67

So now we have in one minute 0.67 miles are covered.

Now distance covered in 25 minutes will be:

0.67*25 = 16.75 miles

Now distance covered in one hour:

1 hour = 60 minutes.

So, 0.67*60 = 40.2 miles

So we have distance covered in 25 minutes-16.5 miles and in 1 hour- 40.2 miles.

I need help with my math assignment

Answers

Answer:

Step-by-step explanation:

Slope m is defined as m=(y2-y1)/(x2-x1) in this case

m=(218-155)/(22-15)=63/7=9

y=mx+b

y=9x+b, using point (15,155) we can solve for the y intercept b

155=9(15)+b

155=135+b, b=20 so the line is

y=9x+20

In thirty days there will be

y=9(30)+20=290 coins

Answer:

Step-by-step explanation:

The zeros of the given function are -3 and 1.

What are zeros of a function?

The zeros of a function, also referred to as roots or x-intercepts, are the x-values at which the value of the function is 0 (f (x) = 0). The zeros of a function can be thought of as the input values that result in an output of 0.

Given is a function f(x) = (x + 3)(x - 1)/(x-2)(x + 2),

We need to find the zeros of the function,

Equate to 0,

(x + 3)(x - 1)/(x-2)(x + 2) = 0

Therefore,

(x + 3)(x - 1) = 0

x+3 = 0 and x-1 = 0

Therefore,

x = -3, x = 1

Hence, the zeros of the given function are -3 and 1.

Simply again
1+2x=-4x-8
Add 4x to both sides
1+2x+4x=-8

1+6x =-8
Subtract 1
6x= -8-1
6x=-9
Divide both sides by 6
Divide x = -9\6
