The acceleration of a car that travels in a straight line at a constant speed of 100 km/h is zero. Average acceleration = (change in velocity)/(time it takes). Since the car's change in velocity is zero, its acceleration is zero.

Answer:

Step-by-step explanation:

Sammy's rabbit can eat 70 pounds of food in 80 days. Part A: At that same rate, how much food will Sammy need to feed his rabbit in 24 days? Part B: How long will it take his rabbit to eat 87.5 pounds of food? Part C: Suppose Sammy buys his rabbit a companion. Together, the rabbits need can eat 95 pounds of food in 65 days. Approximately how much food will Sammy need to buy in order to feed both rabbits inl year ( 365 daya)? Round to the nearest tenth.

Part A

The rabbit can eat 70 pounds of food in 80 days. The unit rate is 70/80 = 0.875 pounds of food per day. Multiply this with the 24 days to get the total amount eaten over that timespan.

24*0.875 = **21**

=========================================================

Part B

x = number of days

The rabbit eats at a unit rate of 0.875 pounds per day. After x number of days pass by, the rabbit has eaten a total of 0.875x pounds of food. Set this equal to 87.5 and solve for x.

0.875x = 87.5

x = (87.5)/(0.875)

**x = 100**

=========================================================

Part C

This is is similar to part A, just with different numbers. We could follow those steps to get the answer, but I'll go another route.

Instead, I'll use a proportion to solve.

(95 pounds)/(65 days) = (x pounds)/(365 days)

95/65 = x/365

95*365 = 65*x

34675 = 65x

65x = 34675

x = 34675/65

x = 533.461538

x = **533.5**

**Answer:**

In a parallelogram, opposite sides are the same length. If PR = ST, then the same would happen for the other sides.

**Step-by-step explanation:**

Which ordered pair (a, b) is the solution to the given system?

2a-5b=1

3a+5b=14

(1, 3)

(3, 1)

(29/5,15)

15,29/5

**Answer:**

2a - 5b = 1

3a + 5b = 14

Let's solve this system using elimination. Add the equations together to cancel the b-terms, then solve for a.

2a - 5b = 1

3a + 5b = 14

+___________

5a - 0 = 15

5a = 15

a = 3

Next, plug 3 for a into either of the equations and solve for b.

2a - 5b = 1

2(3) - 5b = 1

6 - 5b = 1

- 5b = -5

b = 1

Lastly, check all work by plugging both values for their respective variables.

2a - 5b = 1

2(3) - 5(1) = 1

6 - 5 = 1 -- This is true

3a + 5b = 14

3(3) + 5(1) = 14

9 + 5 = 14 -- This is true

The solution to the system of equations is (3, 1).

a tube has a radius of 4 inches and a height of 4 inches. what's its approximate volume?

**Step-by-step explanation:**

that is the same as the volume of a cylinder :

pi×r²×height = pi×4²×4 = pi×64 = 201.0619298... in³

≈ 201 in³

**Volume **is a three-dimensional **scalar **quantity. The **volume **of the tube is **201.0619 inches³.**

A **volume **is a scalar number that **expresses **the amount of three-dimensional **space **enclosed by a **closed surface.**

The **volume **of a **cylinder **is given by the formula as shown below,

Volume of a **cylinder **= πr²h

where r is the **radius **of the cylinder while h is the **height **of the cylinder.

Given that a **tube **has a **radius **of 4 inches and a **height **of 4 inches. Therefore, the volume of the tube will be,

The **volume **of the tube = π × R² × h

= π × (4 inches)² × (4 inches)

= 64π inches³

= 201.0619 inches³

Hence, the **volume **of the tube is **201.0619 inches³.**

You have been asked to analyze the popcorn recipes of three different local theatres in order to figure out which theatre has the best popcorn. In this case, the "best" popcorn is the most buttery! In your quest to find the best, you meet with each theatre manager individually and ask for the ratio of oil to popcorn kernels that they use in their recipes. Here are their responses.

The manager of Theatre A says that they usually go through about 15 cups of popcorn kernels and about 5 cups of oil each weeknight.

The manager of Theatre B says that they order 18 cups of oil and 72 cups of popcorn kernels each week.

The manager of Theatre C says that their concessions use 6 cups of oil and 32 cups of popcorn kernels on a busy Saturday.

You also ask about the amount of salt each theatre uses in their recipe. Their responses are below.

Theatre A uses 2 cups of salt for every 10 cups of oil.

Theatre B uses cup salt for every cup of oil.

Theatre C uses 1 cup of salt for every 6 cups of oil.

For each of the following ratio problems, use a double number line or an equation to solve. Type your answers as numbers.

If Theatre A uses 27 cups of popcorn kernels, how many cups of oil will they use?

_____cups

**Answer: The ratio value of oil to popcorn kernels for theatre C is 6 / 32 = 3 / 16.**

**Step-by-step explanation: Given that the manager of Theatre A says that they usually go through about 15 cups of popcorn kernels and about 5 cups of oil each weeknight.**

**Then, the ratio value of oil to popcorn kernels for theatre A is 5 / 15 = 1 / 5.**

**Given that the manager of Theatre B says that they order 18 cups of oil and 72 cups of popcorn kernels each week.**

**Then, the ratio value of oil to popcorn kernels for theatre B is 18 / 72 = 1 / 4.**

**Given that the manager of Theatre C says that their concessions use 6 cups of oil and 32 cups of popcorn kernels on a busy Saturday.**

**Then, the ratio value of oil to popcorn kernels for theatre C is 6 / 32 = 3 / 16.**
