Answer:

if it's 18 home runs in 9 baseball games

then you're dividing 18 by 9 which is 2 home runs for every 9 baseball games

to prove if you're right (9×2=18)

if it's 11 baseball games then 11×2=22

Andrew McCutchen hit 18 a number of homeruns in 9 baseball games. . which is determined by the given proportion.

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

Given that he hit 18 homeruns in 9 baseball games.

Let the number of homeruns would be x will he have hit in 11 baseball games.

According to the given question, we can write a proportion as

18 homeruns : 9 baseball games = x homeruns : 11 baseball games.

18 / 9 = x / 11

Apply the cross-multiplication operation,

18 × 11 = 9x

9x = 198

x = 198 / 11

Apply the division operation,

x = 18

Therefore, he hit 18 a number of homeruns in 9 baseball games.

Answer:

6.16 miles

Step-by-step explanation:

When solving word problems like these, I like to start by drawing a picture.

So, Glera starts at her home and moves north by 5.8 miles. Then, she walks west by 2.1 miles to the library. The problem wants you to find the distance from her home to the library.

I've attached a drawing I made to help me visualize the problem. The distance from her home to the library is the hypotenuse of the triangle. To solve for it, you would use the equation [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex].

a and b are the sides of the triangle, and c is the hypotenuse.

[tex]5.8^{2}[/tex]  + [tex]2.1^{2}[/tex] = [tex]c^{2}[/tex]

33.64 + 4.41 = [tex]c^{2}[/tex]

38.05 = [tex]c^{2}[/tex]

To find c, you would take the square root of 38.05, which is about 6.16 if you use a calculator.

So, the distance from her home to the library is 6.16 miles!

Answer:

23 inches

Step-by-step explanation:

Let us represent

First piece = x

Second piece = y

A 92-inch is cut into two pieces.

x + y = 92

One piece is three times the length of the other.

x = 3y

Find the length of the shorter piece.

Hence:

x + y = 92

x = 3y

3y + y = 92

4y = 92

y = 92/4

y = 23 inches

Solving for x

x + y = 92

x + 23 = 92

x = 92 - 23

x = 69 inches

The shorter piece is 23 inches long.

Answer:

Aksohia has $146 and Komley has $106

Step-by-step explanation:

The computation of the amount does each one have is shown below:

Let us assume Akoshia money be x

And, komley money be y

x>y

x - 20 = y + 20

x - y = 40

x = 40 + y.........(i)

2(y - 22) = x + 22

2y - 44 = x + 22

Now put the value of x in the above equation

2y - 44 = 40 + y + 22

2y - 44 = 62 + y

y = 62 + 44

= 106

And, x = 40 + 106

= 146

Answer:

35 times, or D

Step-by-step explanation:

A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?

A quick lesson on probability:

The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity  of flipping a coin and getting heads is:

(1 way to get heads) / (2 possible outcomes) = 1/2

Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.  

On to the problem.

There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.

Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.

Using the formula to find the probability, substitute the values we just found.

(the number of ways what you want can happen) / (total number of outcomes possible) =

(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.

Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black

7/20 * 100 = 35 times, or D
