There are currently 21 frogs in a (large) pond. The frog population grows exponentially, tripling every 7 days. How long will it take (in days) for there to be 150 frogs in the pond?
It will take approximately 50 days for the frog population to reach 150 frogs.
Explanation:To find out how long it will take for the frog population to reach 150, we need to determine how many times the population needs to triple to reach that number. We start with 21 frogs and want to reach 150, so we need to triple the population 150 divided by 21, which is approximately 7.14, times. Since the population triples every 7 days, it will take approximately 7.14 times 7, or 50 days, for the population to reach 150 frogs.

( x y 2 z)3 (-9x 2 y z)2
The product of (x y^2 z)^3 and (-9x^2 y z)^2 is found by applying the exponent to each variable inside the parentheses and then multiplying the results together, using exponent rules to simplify. The final simplified expression is 81x^7 y^8 z^5.
Explanation:To find the product of the expressions (x y^2 z)^3 and (-9x^2 y z)^2, we use the properties of exponents. First, we apply the power to each factor inside the parentheses, which means raising each base to the power outside, and then we multiply the corresponding exponents when the same base is found in both terms.
For the first expression (x y^2 z)^3, we get x^3 y^6 z^3, and for the second expression (-9x^2 y z)^2, we have 81x^4 y^2 z^2 after squaring -9 to get 81 and applying the exponent 2 to each variable.
Next, we multiply these results together: x^3 y^6 z^3 × 81x^4 y^2 z^2 = 81x^{3+4} y^{6+2} z^{3+2}, which simplifies to 81x^7 y^8 z^5. The rule of exponent addition when multiplying like bases, x^p x^q = x^{(p+q)}, is applied here to combine the variables with the same base. Our final simplified product is 81x^7 y^8 z^5.
The final answer is [tex]81 x^7 y^8 z^5.[/tex]
To find the product of the expression [tex](x y^2 z)^3 * (-9x^2 y z)^2[/tex], we can follow these steps:
1. Expand the first expression: [tex](x y^2 z)^3 = x^3 (y^2)^3 z^3 = x^3 y^6 z^3.\\[/tex]
2. Expand the second expression: [tex](-9x^2 y z)^2 = (-9)^2 (x^2)^2 y^2 z^2 = 81 x^4 y^2 z^2.[/tex]
3. Multiply the expanded expressions: [tex](x^3 y^6 z^3) * (81 x^4 y^2 z^2) = 81 x^3 x^4 y^6 y^2 z^3 z^2 = 81 x^7 y^8 z^5.[/tex]
Therefore, the final answer is [tex]81 x^7 y^8 z^5[/tex].
2.6x10^-6 write the folliwing number in standard form (decimal)
Final answer:
To express 2.6x10^-6 in standard decimal form, the decimal point is moved 6 places to the left, giving us 0.0000026.
Explanation:
To write 2.6x10^-6 in standard decimal form, start by understanding the exponent. The notation 10^-6 means that we are moving the decimal point 6 places to the left because it is a negative exponent. Therefore, we start with 2.6 and move the decimal point to the left 6 places, which means we have to add zeros to fill in the gaps.
The final expression in standard form will be 0.0000026.
Is 250% of 44 less than 100, greater than 100 but less than 150, or greater than 150? Explain reasoning
50% of 44 is greater than 100 but less than 150 because the value of 250% of 44 is 110 after applying the concept of the percentage.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
250% of 44
Let x be the 250% of 44:
The value of x can be found as follows:
x = (250/100)44
x = 2.5(44)
x = 110
110 > 100
110 < 150
Or
100 < 110 < 150
Thus, 50% of 44 is greater than 100 but less than 150 because the value of 250% of 44 is 110 after applying the concept of the percentage.

Janet took out a loan of $50,000 from Bank of America at 8% on March 19, 2015, which is due on July 8, 2015. Using exact interest, the amount of Janet's interest cost is:
The amount of Janet's interest cost from a loan of $50,000 at an interest rate of 8% from March 19 to July 8, 2015 is $1,160. The calculation is done using the simple interest formula, with time approximated as 0.29 years.
Explanation:The problem asking for the simple interest incurred on a loan taken by Janet can be solved using the formula of simple interest, which is I=PRT in financial mathematics. I is interest, P is the principal amount (initial loan), R is the interest rate, and T is the time.
P (Principal) = $50,000R (Rate of Interest) = 8% per annumT (Time) = Time interval from March 19 to July 8 that turns out to be approximately 3.5 months or about 0.29 years.Substituting these values into the formula, we get:
I = 50000 * 0.08 * 0.29
Calculating this out will give you the total interest, $1160.
So, the amount of Janet's interest cost is $1,160.

Which expression is equivalent?
11 − 9(−2x − 3)
A) 18x + 38
B) −4x + 6
C) 18x − 38
D) −4x − 6
The expression equivalent to 11 - 9(-2x - 3) is 18x + 38 after applying the distributive property and rules for multiplying numbers with different signs. This corresponds to option A.
Explanation:To find which expression is equivalent to 11 − 9(−2x − 3), we need to apply the distributive property and the rules for multiplying numbers with different signs. The distributive property tells us to multiply the number outside the parentheses by each term inside the parentheses. So, let’s apply this to the expression:
First, distribute the -9 to both -2x and -3: -9(−2x) + -9(−3).According to the multiplication rules for signs, multiplying two negative numbers results in a positive number. So, -9(−2x) becomes +18x, and -9(−3) becomes +27.Now the expression looks like this: 11 + 18x + 27.Add the constant terms 11 and 27 to get 38. The expression is now 18x + 38.Therefore, the expression equivalent to 11 − 9(−2x − 3) is 18x + 38, which corresponds to option A.

you want to buy a CD that cost $18.50. The sales-tax rate in your states is 4.5 percent. How much sales tax will you pay for this CD?
4.5% = 0.045
multiply 18.50 by 0.045 foe the amount of sales tax
18.50 * 0.045 = 0.83
they pay 0.83, which is 83 cents in sales tax
Jay purchased tickets for a concert over the internet. To place an order, a handling charge of 5$ per ticket is charged. GST of 5% was also charged on ticket price and handling charges. If the total charge for 2 tickets is 201.16, what is the price per ticket.
Answer is 90.79 but I need an explanation on how they got that answer thanks
The price per ticket (before any additional charges) is approximately $90.79. Let's assume the price of each ticket before any additional charges (handling charge and GST) is "x" dollars.
Given that a handling charge of $5 is charged per ticket, the total handling charge for 2 tickets will be $5 * 2 = $10.
Now, let's calculate the total cost of the tickets after adding the handling charge:
Total cost of tickets (before GST) = 2x + 10
Now, the GST of 5% is charged on the ticket price and handling charges. The GST amount can be calculated as:
GST amount = 5% of (2x + 10) = 0.05 * (2x + 10) = 0.1x + 0.5
The total charge for 2 tickets, including the handling charge and GST, is given as $201.16. So, we can set up the equation:
Total cost of tickets (including GST) = Total cost of tickets (before GST) + GST amount
$201.16 = (2x + 10) + (0.1x + 0.5)
Now, solve for "x":
2x + 10 + 0.1x + 0.5 = 201.16
2.1x + 10.5 = 201.16
2.1x = 201.16 - 10.5
2.1x = 190.66
x = 190.66 / 2.1
x ≈ 90.79
So, the price per ticket (before any additional charges) is approximately $90.79.
