There are 1,342 players in the baseball league. That is

4 times the number of players in the football league.

How many players are in the football league? Write an

equation. Then solve.

### Answers

**Answer:**

335.5

**Step-by-step explanation:**

if we take your second sentence it means that 1342/4 so when you do the long division you will get it

**Solution:**

Note that:

1,342 players = Baseball team.Clue: 1,342 players is 4 times the number of players in the football league.

Let's reread the clue carefully.

{1,342 players} {is} {4 times the number of players in the football league.}

↥ ↥ ↥

1342 = 4f

This creates the equation "1342 = 4f". Now, let's solve the equation.

1342 = 4f=> f = 1342/4=> f = 335.5 players

PLEASE HELP ME!!!

Based on the formula for triangles, A = bh/2, I did that and got 24.5 but since there are 2 of the triangles I did 24.5 x 2 = 49. I know that the line in the triangle means they are congruent. But are they congruent to show that the base and height is 7 x 7 for the one that the line is crossing of does it show that itś 7x7 for both triangles?

I found the area of the square and subtracted that from the area of the triangles to get 147.

My area of the triangles is 49ft^2

My area of the pebbles is 147ft^2.

Is this correct?

### Answers

**Answer:**

98 feet

**Step-by-step explanation:**

area= I x W

14x7

98 feet

*Answer:*

147 ft²

*Step-by-step explanation:*

The simple and best way would be to find the area of the square and subtract that from the area of the triangles.

[tex]14*14=196[/tex]

If side a and b of the triangle(s) is 7, then the area is 24.5.

[tex]A=\frac{ab}{2}=\frac{7.7}{2}=24.5[/tex]

Then you add the two triangles together (since there's two unshaded regions) and subtracted that from the whole square.

[tex]24.5*2=49[/tex]

[tex]196-49=147[/tex]

The area of the two triangles is 49 ft²^2.

The area of what the pebbles cover is 147 ft^2.

So yes, you are correct.

2) Abby made 5 1/2 cups of banana pudding. She served 7/8 cup of the pudding to her kids for dessert.

How any cups of banana pudding does Abby have left

after dessert?

### Answers

**Answer:**

37/8

**Step-by-step explanation:**

we are going to create 5 1/2 into an improper fraction for now, so it is easier to manipulate.

5 1/2 = 11/10

in order to find the answer, we need to set them both to a common denominator(we need to make sure they have the same denominator so it is easier to subtract)

11/2 if we just take 1 of the cups that Abby made and subtract that by 7/8 that give us the answer

11/2 - 1 = 9/2

we will now us the cup we subtracted from that and "give it to the kids"

1 = 8/8

so

8/8 - 7/8 = 1/8

so we have 1/8 leftover from that cup, so we can add that back

since 1/8 is a hard number to just add off the top of your head, we can just change the denominator of 9/2 into 8 instead of 2:

9/2 = 36/8

so

1/8 + 36/8 = 37/8

so since 37/8 cannot be simplified anymore, the answer is

**37/8**

4) Rebecca owns a health food store. In March, sales were $122,000. In April, sales were

$108,770. What was the rate of change?

### Answers

**Answer:**

-0.13 or -13%

**Step-by-step explanation:**

Rate of change = [(final value) - initial value)] / (initial value)

= (108,000 - 122,000) / (108,000)

= -14,000/108,000 = -14/108 = -0.13 = -13%

The **sales** at Rebecca's health food store **fell** by **$13230** in **1 month.**

What is Rate?

Rate represents how a **specific quantity** varies with respect to an other **independent quantity. **

Given is Rebecca owns a **health food store, **such that in **march**, the sales were** $122,000 **and in** April**, the sales were **$108,770**.

Rate of change of **sales **with respect to **time (in months) **can be calculated as follows -

**r = (S₂ - S₁)/(t₂ - t₁)**

r = (108770 - 122000)/(4 - 3)

r = - 13230/1

**r = - 13230**

Therefore, the **sales** at Rebecca's health food store **fell** by **$13230** in **1 month.**

Parallel and Perpendicular Lines

Identify the choice that best completes the statement or answers the question. Which set of lines are considered parallel?

### Answers

Line ST and line QR

Or

Line QS and line RT

line QS **parallel** to RT are parallel and

QR parallel to ST

Parallel lines are lines in a two-dimensional plane that never **intersect**, no matter how far they are extended. They have the same slope and will remain equidistant from each other at every point. In other words, they maintain a constant distance apart along their entire length.

Parallel lines have the following key characteristics:

1. They have the same **slope**, which means they have the same steepness or incline.

2. They **never** intersect, so they do not share any common points.

3. The **distance** between them remains the same at any point along their length.

4. They can be in any orientation, such as horizontal, vertical, or at an angle to each other.

So, from **figure** we can see that line QS parallel to RT are parallel and

QR parallel to ST
