You take measurements of the distance traveled by an object that is increasing its speed at a constant rate. The distance traveled d as a function of time t can be modeled by a quadratic function. What is the quadratic function that models distances of 21 ft at 1 s, 59 ft at 2 s, and 141 ft at 4 s?

Answers

Answer 1

Answer:

Follows are the solution to this question:

Step-by-step explanation:

Given:

Pam has 9 bags of apples. Each bag contains
6 apples. There are 3 bags of red apples and
1 bag of green apples. The rest of the bags
contain yellow apples. How many more
yellow apples are there than red apples?

Answers

Answer

There are 12 more yellow apples than red.

Step-by-step explanation:

How exactly?

First find how many bags of YELLOW apples. 9 bags in total and there is 1 bag of green apples and 3 bags of red apples so 9-(3+1)= 5 bags of YELLOW apples.

So we know there is 1 bag of GREEN apples and since each bag holds/ contains 6 apples we also know that 1x6= 6 so  g or GREEN apples is 6.

Now lets find how many RED apples there are :D. There are 3 bags of RED apples each containing 6 apples so we know 6+6+6= so r or RED apples is 18.

So, now we find how many YELLOW apples there are. 6 apples in each bag and there are 5 bags remaining for YELLOW apples we do 6x5 which equals 30 apples ( WOW My girl PAM?! She looove her yellow apples)

Lastly we know there are 30 yellow apples and 18 red apples we also know the question asked " How many MORE yellow apples are there than red apples?" so this means we subtract. 30-18= 12 MORE YELLOW APPLES THAN RED APPLES

A coach is buying snacks for 22 players at a soccer match. She pays a total of $77 to buy each player a bottle of water and an energy bar. The price of one energy bar is $2. Which quantity is unknown? The price of a bottle of water. Let w equal the price of a bottle of water. Write an equation that represents the situation.

Answers

77*22=    1694                     2*22=44

Step-by-step explanation:

22w + 44 = 77 is the equation which represents the situation and the price of a bottle of water is $1.5.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Let w be the price of a bottle of water.

The coach is buying 22 bottles of water and 22 energy bars, which cost a total of $77.

The cost of 22 energy bars is $2 x 22 = $44.

So the total cost of 22 bottles of water and 22 energy bars is:

22w + 44 = 77

We can simplify this equation by first subtracting 44 from both sides:

22w = 33

Then, we can solve for w by dividing both sides by 22:

w = 1.5

Therefore, 22w + 44 = 77 is the equation which represents the situation and the price of a bottle of water is $1.5.

A mafia hideout was just raided and two large groups of criminals escaped. One group filled 8 cars and 8 vans with a total of 240 people. The second group filled 4 cars and 1 van with a total of 54 people.

Answers

Answer:

Number of people in each car = x = 8

Number of people in each van = y = 22

Step-by-step explanation:

Let

Number of people in each car = x

Number of people in each van = y

8x + 8y = 240 (1)

4x + y = 54 (2)

From (2)

4x + y = 54 (2)

y = 54 - 4x

Substitute y = 54 - 4x into (1)

8x + 8y = 240 (1)

8x + 8(54 - 4x) = 240

8x + 432 - 32x = 240

8x - 32x = 240 - 432

-24x = -192

x = -192/-24

x = 8

Substitute x = 8 into (2)

4x + y = 54 (2)

4(8) + y = 54

32 + y = 54

y = 54 - 32

y = 22

Number of people in each car = x = 8

Number of people in each van = y = 22

Theon took his wife and 2 children to a football game . Children 's ticket costs 1/3 the price of an adult ticket. Ticket Prices.Adult 's Ticket= ,Children =40.00. Theon received 10% discount on the total cost of 4 tickets. Calculate the amount of money Theom paid and how many adults ticket.​

Answers

Answer:

288

Step-by-step explanation:

If the price of a children's ticket is 1/3 of an adult's, and we know that the price of a children's ticket = 40, than we also can calculate that the price of an adult ticket is 40 * 3 = 120

So the question boils down to how many adults and children. Well, Theon has a wife and 2 kids so we can safely assume that there are two adults and two children total (Theon and wife are adults) (2 children are children)

120*2 + 40 * 2 = 320

However, we need to eliminate 10% of the value since they get a discount

320 - 0.10 * 320 = 320 - 32 = $288

How do you solve an inequality, then verify the solution by subsituting 3 different numbers?

Answers

Answer and Step-by-step explanation:

To solve an inequality, you must solve for the variable. Let's look at an example:

4x + 2 > 10

We solve for x by subtracting 2 from both sides, then dividing 4 on both sides.

(Solve as if you were solving a regular equation)

4x > 8

x > 2

We get x > 2 as our inequality.

To plug in 3 values, simply plug in any number that is greater than 2. That would be the solution to the inequality.

If when solving the inequality and you have to divide by a negative, the sign will change. Ex:

-5x > 25

x < -5

To show that the sign should switch, let's solve it this way.

-5x > 25

0 > 25 + 5x       Add the 5x to both sides.

-25 > 5x            Subtract the 25 from both sides

-5 > x                Divide by 5 from both sides.

As we can see, the inequalities turn out to be the same, which is why you flip the sign when you divide.
