Ana was washing dishes at the end of her shift at a restaurant. She washed 40 plates from 7:20 to 7:30.
When she finishes washing all the plates, her shift will end.
(a) If she started washing plates at 7:10 and ended at 7:35, estimate how many plates she washed in
total. Explain your reasoning.
(b) Write an equation to represent how many plates Ana has left to wash at a particular time after her
start at 7:10. Explain your reasoning.

Answer:

D. a = 0.0022

    b = 2.31

    r = 131%

Step-by-step explanation:

I calculated it logically

The starting value a, the growth factor b, and the growth rate r if Q = abt = a(1 + r)t. Write r as a percent. \(Q = 0.0022(2.31)^t\) is Option a) a = 0.0022, b = 2.31, r = 131%

In the given formula, Q = abt = a(1 + r)t, the variables represent the following:

- "a" is the starting value.

- "b" is the growth factor.

- "r" is the growth rate expressed as a percentage.

Looking at the expression given: \(Q = 0.0022(2.31)^t\), we can identify the values as follows:

- "a" = 0.0022

- "b" = 2.31

To find the value of "r," we need to rewrite the formula as Q = a(1 + r)^t and then solve for "r."

Given \(Q = 0.0022(2.31)^t\), we can rewrite it as:

\(Q = a(1 + r)^t\)

\(0.0022(2.31)^t = a(1 + r)^t\)

Now, we can divide both sides of the equation by "a" to isolate the term

\((1 + r)^t\):

\((2.31)^t = 1 + r\)

Next, subtract 1 from both sides to solve for "r":

\(r = (2.31)^t - 1\)

Since the value of "t" is not specified, we cannot determine the exact numerical value of "r" without knowing the specific time "t." However, we can express "r" as a percentage, as requested.

So, the correct answer is: a) a = 0.0022, b = 2.31, r = 131%

To solve the savings plan balance, we have to calculate the interest for 19 months. The formula for calculating interest for compound interest is given below:$$A = P \left(1 + \frac{r}{n} \right)^{nt}$$where A is the amount, P is the principal, r is the rate of interest, t is the time period and n is the number of times interest compounded in a year.

The given interest rate is 11% per annum, which will be converted into monthly rate and then used in the above formula. Therefore, the monthly rate is $r = \frac{11\%}{12} = 0.0091667$.

The monthly payment is $PMT = $250. We need to find out the amount after 19 months. Therefore, we will use the formula of annuity.

$$A = PMT \frac{(1+r)^t - 1}{r}$$where t is the number of months of the plan and PMT is the monthly payment. Putting all the values in the above equation, we get:

$$A = 250 \times \frac{(1 + 0.0091667)^{19} - 1}{0.0091667}$$$$\Rightarrow

A = 250 \times \frac{1.0091667^{19} - 1}{0.0091667}$$$$\Rightarrow

A =250 \times 14.398$$$$\Rightarrow A = 3599.99$$

Therefore, the savings plan balance after 19 months with an APR of 11% and monthly payments of $250 is $3599.99 (approx).

Answer:

The farmer needs 24 crates to hold the carrots.

Step-by-step explanation:

To determine how many crates the farmer needs to hold the carrots, knowing that his farm has 4.8 acres of land, where he can harvest 120 pounds per acre, and that each crates can hold up to 24 pounds of carrots, the following calculation must be performed:

(4.8 x 120) / 24 = X

576/24 = X

24 = X

Thus, the farmer needs 24 crates to hold the carrots.

Answer 25:

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

You can solve for "x" by rearranging the equation and getting the "x" by itself on one side. Remember, whatever you do to one side of the equation, you must do to the other side.

-6 + x = -2                         <----- Original equation
+6         +6                        <----- Add 6 to both sides to isolate "x"

0 + x = 4                           <----- After the addition

x = 4                                 <----- Rewrite

Answer:

None of the above (x = 4) \( \sf {} \)

Step-by-step explanation:

Now we have to,

→ find the required value of x.

The equation is,

→ -6 + x = -2

Then the value of x will be,

→ -6 + x = -2

→ x = -2 + 6

→ [ x = 4 ]

Using a system of equations, the height of the tree would be 12.80 meters.

Equating the height and shadows of the tree and pole :

Height of pole / shadow of pole = height of tree / shadow of tree

Representing the equation thus :

Let the height of the tree = h

3/4 = h/17

Cross multiply

4h = 17 × 3

4h = 51

Divide both sides by 4

h = 51/4

h = 12.75.

Hence, the height of the tree to the nearest tenth of a meter is 12.80 meters.

Two reasons for the use of measurement tools are:

1. Using reliable and valid measurement tools ensures that the data collected is accurate and trustworthy, providing the researcher with more confidence in their conclusions.

2. Using reliable and valid tools reduces the amount of time needed to develop a new measurement tool, as the researcher can simply adapt an existing tool to meet their research needs. This allows the researcher to focus more of their effort on the other aspects of the project.

1. Using reliable and valid tools can help the researcher reduce the likelihood of bias in their results, as the tools have already been shown to be free of any potential bias. This helps to ensure that the results of the study are as objective as possible.

2. Using reliable and valid tools can also help to minimize the potential for errors and misinterpretation of data, as the tools are already proven to be valid and reliable. This helps to ensure that the results are as accurate as possible.

3. Finally, using reliable and valid tools can help to reduce the amount of effort and resources needed for data collection, as the researcher does not have to spend time and energy developing their own measurement tools. This can help to save time and money in the long run.
