Final answer:

The expression simplifies using multiple properties of exponents, including the power of a product, properties of exponents for multiplication and division, the zero exponent property, and squaring.

Explanation:

The expression you're asking about applies multiple properties of exponents to simplify the given expression. To start, applying the power of a product property, it simplifies [tex](4*9)^5[/tex] to [tex]4^5*9^5[/tex]. Following that, the property of exponents for division is used to combine [tex]4^{-5[/tex] and [tex]4^5[/tex], leading to [tex]4^0[/tex], as well as [tex]9^5[/tex] and [tex]9^{-3[/tex], resulting in [tex]9^2[/tex]. The zero exponent property translates [tex]4^0[/tex]into 1. Lastly, the square of 9 gives the end result of 81.

In summary, these are the properties applied: power of a product, properties of exponents for multiplication and division, zero exponent property, and squaring.

Shan's dumpling house can produce 100 dumplings using one worker and 175 dumplings using two workers. what is the marginal product of the second worker?
a.25 dumplings
b.75 dumplings
c.175 dumplings
d.275 dumplings

Answers

Marginal product is defined as the incremental change in output that occurs due to a change in the input signals.

It is calculated on two steps:
1- Find the change that occurred to the outputs
2- Divide this change by the additional inputs

For the problem we have here:
Step 1:
old output = 100 dumplings
new output = 175 dumplings
change that occurred = 175 - 100 = 75
Step 2:
This change occurred as a result of adding 1 worker
Therefore:
marginal product = 75/1 = 75

Answer: (b)

The marginal product of the second worker is b. 75 dumplings.

To find the marginal product of the second worker, we need to determine how many additional dumplings the second worker is able to produce compared to the first worker. The marginal product (MP) of a worker is calculated as follows

[tex]\[ MP = \text{Total production with two workers} - \text{Total production with one worker} \][/tex]

Given:

[tex]\[\]\[ \text{Total production with one worker} = 100 \text{ dumplings} \]\[ \text{Total production with two workers} = 175 \text{ dumplings} \][/tex]

Substitute the given values into the formula:

[tex]\[\]\[ MP = 175 \text{ dumplings} - 100 \text{ dumplings} \]\[ MP = 75 \text{ dumplings} \][/tex]

Therefore, the volume of the greenhouse is 129.63 cubic yards.

The weight of 10,000 identical samples of a substance is 10 pounds. What is the weight of 100 samples?

Answers

Okay. So, the weight of 10,000 samples is 1 pound. To find the weight of each sample, we can do 10/10,000, which would give us 0.001. Each sample weighs 0.001 pound. We can multiply that times 100 to find the weight of 100 samples. 0.001 * 100 = 0.1. The weight of 100 samples is 0.1 pound.

Answer: 0.1

Step-by-step explanation: Okay. So, the weight of 10,000 samples is 1 pound. To find the weight of each sample, we can do 10/10,000, which would give us 0.001. Each sample weighs 0.001 pound. We can multiply that times 100 to find the weight of 100 samples. 0.001 * 100 = 0.1. The weight of 100 samples is 0.1 pound.

Answers

Let the fist number in the sequence be x, we have 6 consecutive numbers. This means that the numbers would be:
x , x+1 , x+2 , x+3 , x+4 and x+5

We know that the sum of these numbers is 387, therefore:
x + x+1 + x+2 + x+3 + x+4 + x+5 = 387
6x + 15 = 387
6x = 372
x = 62

Therefore, the sixth number in the sequence would be : x+5 = 62+5 = 67

Lisa wants to buy a phone card for $5. Company X charges $0.49 for the first minute and $0.16 for each additional minute. Company Y charges $0.57 for the first minute and $0.12 for each additional minute. If Lisa makes just one call, which phone company gives her more minutes for $5? How many more minutes?

Answers

So for $5, let's calculate each company's minutes for that much money.

Company X: First subtract the time for the first minute.

5 - 0.49 = 4.51

Then divide by 0.16, and you get about 28 minutes.

28 + the original 1 minute = 29 minutes

Company Y: $5 - 0.57 = 4.43

4.43 / 0.12 = about 36 + the original one minute = 37 minutes

So Company Y gives her more minutes for 5 dollars, and also 8 more.

Lisa had 1750 stamps. Mark had 480 fewer stamps than Lisa. Lisa gave some stamps to Mark. Now Mark has three times as many stamps as Lisa. How many stamps did Mark have at first? How many stamps does Lisa have now? Explain.

Answers

Given that Lisa had 1,750 stamps and Mark had 480 fewer stamps than Lisa.

Thus, the number of stamps Mark had is 1,750 - 480 = 1,270

Given that Lisa gave some stamps to Mark which makes Mark to have three times as many stamps as Lisa.

Let the number of stamps that Lisa gave to Mark be x, then

[tex]3(1,750 - x) = 1,270 + x \\ \\ \Rightarrow5,250-3x=1,270+x \\ \\ \Rightarrow x+3x=5,250-1,270 \\ \\ \Rightarrow 4x=3,980 \\ \\ \Rightarrow x= \frac{3.980}{4} =995[/tex]

Thus, Lisa gave Mark 995 stamps.

Therefore, the number of stamps that Lisa have now is 1,750 - 995 = 755.

n = the number of times interest is compounded each year
t = the time in years

Find how long it takes a $2,200.00 investment to earn $210.00 in interest if it is invested at 10% compounded monthly.

It will take ___ years. (Round answer to 3 decimal places.)

Answers

same here, the interest earned is 210, the principal is 2200, so the accumulated amount is 2410.

[tex]\bf \qquad \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\to &\$2410\\ P=\textit{original amount deposited}\to &\$2200\\ r=rate\to 10\%\to \frac{10}{100}\to &0.10\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{monthly, thus twelve} \end{array}\to &12\\ t=years \end{cases}[/tex]

[tex]\bf 2410=2200\left(1+\frac{0.1}{12}\right)^{12t}\implies \cfrac{2410}{2200}=\left(1+\frac{1}{120} \right)^{12t} \\\\\\ \cfrac{241}{220}=\left(\cfrac{121}{120} \right)^{12t}\implies log\left( \frac{241}{220} \right)=log\left[ \left(\frac{121}{120} \right)^{12t} \right]\\\\\\ log\left( \frac{241}{220} \right)=12t\cdot log\left(\frac{121}{120} \right)\implies \cfrac{log\left( \frac{241}{220} \right)}{12 log\left(\frac{121}{120} \right)}=t\implies 0.915 \approx t[/tex]

Final answer:

It will take approximately 1.459 years for a $2,200.00 investment to earn $210.00 in interest if it is invested at 10% compounded monthly.

Explanation:

To find how long it takes a $2,200.00 investment to earn $210.00 in interest if it is invested at 10% compounded monthly, we can use the formula A = P(1+rn)^(nt). Plug in the values: A = 2200 + 210 = 2410, P = 2200, r = 0.10 (10%), n = 12 (compounded monthly), and t = ?

2410 = 2200(1 + 0.10/12)^(12t). Divide both sides by 2200 to isolate the expression:

1.095 = (1 + 0.10/12)^(12t). Take the natural logarithm of both sides to remove the exponent:

ln(1.095) = 12t * ln(1 + 0.10/12). Solve for t:

t = ln(1.095) / (12 * ln(1 + 0.10/12)). Use a calculator to find the value of t, which is approximately 1.459 years when rounded to 3 decimal places.

Find p((5 on green die and 3 on red die) or (3 on green die and 5 on red die)). (enter your answer as a fraction.)

Answers

1/72 This is because the odds that, on two dice, two specific numbers get rolled is 1/36. But since the number has to be rolled on a specific dice, that doubles the fraction.

The probability of rolling a 5 on the green die and a 3 on the red die, or a 3 on the green die and a 5 on the red die is calculated by summing their individual probabilities, leading to a final probability of 1/18.

To solve this probability question, we will use the fundamental counting principle and basic probability rules. We have two six-sided dice, one green and one red. The question specifies two separate events:

The green die shows a 5 and the red die shows a 3.

The green die shows a 3 and the red die shows a 5.

Since each face on a fair six-sided die has an equal chance of appearing, the probability of getting any specific number is 1/6. When we roll two dice, the probability of any specific outcome is (1/6) x (1/6), which simplifies to 1/36.

Since there are two independent events that satisfy the question, we can add the probabilities of each event occurring:

Probability of a 5 on green die and 3 on red die = 1/36

Probability of a 3 on green die and 5 on red die = 1/36

Adding them up, we get 1/36 + 1/36 = 2/36, which simplifies to 1/18. Therefore, the probability of getting either a (5 on the green die and 3 on the red die) or (3 on the green die and 5 on the red die) is 1/18.
