HURRYY! Will give Brainliest! The amount of sports drink in a cooler during practice is modeled by the equation

y = -24x + 648, where y is the number of ounces in the cooler after practice and x is the number of players at practice who take drinks from the cooler.

Based on the information in the equation, which statements are true?





A. The cooler is meant to be used by only 24 players.

B. Before practice, there are 648 ounces of sports drink in the cooler.

C. If 24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink.

Answers

Answer:

Step-by-step explanation:

ounces of sports drink in the cooler.

C. Each player is expected to drink 24 ounces of sports drink during practice.

D. If no players take drinks from the cooler, there will be 648 ounces of sports drink in the cooler after practice.

Statement B is true: Before practice, there are 648 ounces of sports drink in the cooler, as the y-intercept of the equation is 648.

Statement C is not true: The coefficient of x, -24, does not represent the amount of sports drink each player is expected to drink. It represents the rate at which the amount of sports drink in the cooler decreases as players take drinks.

Statement D is not true: If no players take drinks from the cooler, x would be 0, and the amount of sports drink in the cooler after practice would be y = -24(0) + 648 = 648. However, this situation is not realistic, as players would normally take drinks from the cooler during practice.

Statement A is not true: The equation does not limit the number of players who can use the cooler. The equation only models the rate at which the amount of sports drink in the cooler decreases as players take drinks.

B.
In mx+b, b is initial value meaning they started with 648 ounces

Write and evaluate an expression that tells you to subtract 6 from 9 then subtract the difference from 12 and then multiply by 3 use at least two types of grouping symbols

Answers

Step-by-step explanation:

One possible expression using two types of grouping symbols is:

3 × [(12 - (9 - 6))]

This expression first subtracts 6 from 9 to get a difference of 3, then subtracts that difference from 12 to get a result of 9. Finally, it multiplies 9 by 3 to get a final answer of 27. The grouping symbols used are parentheses to group the subtraction of 6 from 9, and then another set of parentheses to group the subtraction of that difference from 12. The outermost grouping symbols are the multiplication symbol and the pair of brackets used for clarity.

Answer:

198

Step-by-step explanation:

length =11

width=18

Length times width = area

11 times 18 equals 198

i hope this helps! <3

Page 1, Answer:
168 cm

Explanation:

First we should find the area of the non-shaded parts

Length: 5cm
Width: 4cm
5x4=20
1st square= 20 cm

Length: 5cm
Width: 2cm
5x2= 10
2nd square= 10 cm

Now we add:
20+10=30

Shaded part:
11x18=198

We have to subtract the shaded part by the non shaded part:
198-30=168

Answer= 168cm


Page 2:

Answer 1:
Both are equal

Explanation:

Both are equal because:

A: 8+8+2+2

16+4=20
A=20cm

B: 5+5+5+5
5x4=20
B=20 cm

Answer 2:
16

Explanation:

Since we are already given the product we need to find the factors, square has 4 equal sides so we have to divide by 4:

64/4=16
Ans=16cm

Answer 3:
62cm

Explanation:
We need to divide the shape into 2.

Rectangle 1:
10+5+?+?

Since we already know what one side is it will be the same on the other side:

10+10+5+5
20+10=30

Rectangle 1=30cm

Rectangle 2:

Here we start to add and subtract:

Length: 10-5=5

Width: 6+5=11

5+5+11+11
10+22=32
32 cm

Total:
Now that we know both perimeters we add:

32+30=62

Total=62cm

There are two spinners containing only blue and green slices.
Spinner A has 4 green slices and 16 blue slices.
All the slices are the same size.
Spinner B has 9 green slices and 3 blue slices.
All the slices are the same size.

Each spinner is spun.
List these events from least likely to most likely.
Event 1: Spinner B lands on a blue slice.
Event 2: Spinner B lands on a green or blue slice.
Event 3: Spinner A lands on a yellow slice.
Event 4: Spinner A lands on a green slice.

Answers

Answer:

Step-by-step explanation:

2,1,4,3
explanation
event 2 has to happen because there are no other colors.
event 1 will likely come next because there are more blue slices than green slices.
event 4 will come best because it is less likely for it to land on a green slice than a blue slice
event 3 can never happen because there are no yellow slices

A wallet contains 23 bills. All the bills are $1 bills and $5 bills. There are 7 more $1 bills than $5 bills. How much money does the wallet contain?

Answers

Answer:

Step-by-step explanation:

Let's say x is the number of $1 bills and y is the number of $5 bills. We know that:

x + y = 23

x = y + 7

We can use rearrange the second equation and add them together to find x. Then, we can plug x into any one of our equations to find y and calculate how much money is in the wallet.

x + y = 23

x - y = 7

2x = 30

x = 15 $1 bills

15 = y + 7

y = 8 $5 bills

15 * $1 + 8 * $5 = $15 + $40 = $55

Hope this helps!

Grade#7

Answers

Answer:

a) formula of parallelogram- BASE × HEIGHT

Step-by-step explanation:

Area:-B×H

area- 8×14

The formula of the area of a parallelogram is : Base x Height

Therefore :

Area - base x height
Area- 8 x 14
= 112cm squared

Martin used a coordinate plane to design the garden shown. Each unit on the grid represents 10 yards.

How many square yards will the garden be after it is built? What is the total AREA of the garden?

Answers

The best way to solve this is to break the shape up into areas you know how to solve.

Lets divide this into the big rectangle being separated from the smaller rectangle at the bottom.

To find the height of the big rectangle, subtract one y-coord of 30 from the other y-coord 80.

80-30=50

To find the length of the big rectangle, subtract one x-coord of 10 from the other x-coord of 100.

100-10= 90

Multiply these to get the area of the big rectangle:

90 x 50 = 4500 units squared

Next, find the smaller recatngle’s area by repeating the previous steps:

Height: 30-10 = 20
Length: 70-40 = 30

Now find the area:

20 x 30 = 600 units squared

Finally, add both of these areas up to find the total area for the original shape:

4500 + 600 = 5100 units squared

a. What is the least number of bags of each fruit you need to have the same number of apples, oranges, and bananas? I

b. How many of each type of fruit do you have?

c. There must be at least 5 but no more than 10 of each type of fruit in each basket.

How many different ways can you arrange the fruit baskets when using all of the fruit? Explain your reasoning.

Answers

Answer:

You will need to find the least common multiple of 20,16, and 32. The least common multiple of all those will be 160. you will need 8 bags of apples, 10 bags of oranges, and 5 bags of bananas. so for a I believe it would be 8 bags of apples 10 bags of oranges and 5 bags for bananas. as for b it should be 160. and for c  you could arrange either 5 of each fruit for 32 baskets, 10 of each for 16 baskets, or 8 of each for 20 baskets

Doira has a company that sells plants. She sells 34 for plants for $9,000 each her first day. The next couple days she sells 34 for $99,999 each. If she keeps selling them for $99,999 each for 100 weeks,how many plants will she have sold? How much money will she have made?

Answers

Answer:

1)23,800 plants.

2)$2,380,068,200

Step-by-step explanation:

1) if Doira sells 34 plants for $99,999 each for 100 weeks, she will have sold a total of 23,800 plants.

2.On the first day, Doira sold 34 plants for $9,000 each, so she made a total of 34 x $9,000 = $306,000.

In the following days, she sold 34 plants for $99,999 each, so her daily earnings were 34 x $99,999 = $3,399,966.

If she continues to sell 34 plants for $99,999 each for 100 weeks, she will sell a total of 34 x 100 x 7 = 23,800 plants.

Her total earnings from selling 34 plants for $99,999 each for 100 weeks will be 23,800 x $99,999 = $2,379,762,200.

Adding her earnings from the first day, her total earnings will be $2,379,762,200 + $306,000 = $2,380,068,200.

Answer: she would sell 340 plants and make $9,999,900

Step-by-step explanation:

34 x 100 =340

99, 999 x 100 = 9,999,900

From a log of wood of length (8x+12) m, a piece of length (4x+3) m was cut. Find the length of the remaining log of wood.


Grade#7

Answers

Answer: 4x+9

Step-by-step explanation: (8x+12)- (4x+3)

Answer: (4x+9)

Step-by-step explanation:

Log of wood = (8x+12)

piece length = (4x+3)

So, (8x+12) - (4x+3)

=> (8x+12) - 4x - 3

=> 8x-4x +12 -3

=> 4x + 9

So, the length of the remaining piece of wood = (4x+9)
