Answer:

-4320t^2

Step-by-step explanation:

Use Pascal's triangle to figure out the variables.

In the 5th expansion, we see that the 4th term is:

10x^2 y^3

Plug in the values,

10*(4)^2 * (-3)^3 = -4230.

However, since the -3 in the original expression does not have a variable next to it, we do not include it in our answer.

Therefore, the 4th term is -4230t^2

Answer:-3840t^4

Final answer:

When 2 pizzas, each cut into 8 slices, are equally shared among 3 friends, each person would eat 5 and 1/3 slices of pizza.

Explanation:

The question involves dividing a certain number of pizza slices equally among friends. Initially, we have 2 pizzas and each pizza is cut into 8 slices, making a total of 16 slices. To find out how many slices each person ate when the amount is the same for everyone, we simply divide the total number of slices by the number of friends.

Since a pizza slice cannot be split into a third naturally, practically, each friend would eat 5 slices and a little bit more from another slice.

The number of players remaining after 5 rounds is equal to 4 players.

An exponential function refers to a mathematical function whose numerical values are generated by a constant that is raised to the power of an argument.

Mathematically, the number of players remaining after 5 rounds is given by:

f(x) = neˣ

f(x) = 128 × (1/2)⁵

f(x) = 128 × 0.03125

f(x) = 4 players.

Answer:

83.6 mL

Step-by-step explanation:

Given 440 mL of 19% acid solution. This means the whole volume of this acid solution is 100%. Let x mL be the volume of pure acid in this solution.

Then

[tex]440\ mL - 100\%\\ \\x\ mL - 19\%[/tex]

Write a proportion:

[tex]\dfrac{440}{x}=\dfrac{100}{19}[/tex]

Cross multiply:

[tex]100\cdot x=440\cdot 19\\ \\x=\dfrac{440\cdot 19}{100}\\ \\x=\dfrac{8,360}{100}\\ \\x=83.60\ mL[/tex]

Final answer:

In 440 milliliters of a 19% solution, there are 83.6 milliliters of pure acid, calculated by multiplying the percentage (converted to a decimal) by the total volume of the solution.

Explanation:

To find out how much pure acid is in 440 milliliters of a 19% solution, you need to use the concept of percentage concentration in chemistry. The percentage concentration tells us how much of a substance is present in a solution compared to the total amount of the solution.

In this case, we have a 19% acid solution. This means that 19% of the solution's total volume is pure acid. To calculate the volume of pure acid, you multiply the total volume of the solution by the percentage (expressed as a decimal).

Calculation:

Convert the percentage to a decimal: 19% = 0.19

Multiply this decimal by the total volume of the solution: 0.19 × 440 mL

This gives us the volume of pure acid: 0.19 × 440 mL = 83.6 mL

So, there are 83.6 milliliters of pure acid in 440 milliliters of a 19% acid solution.

Answer: [tex]y = -2x + 9[/tex]

Step-by-step explanation:

The formula for finding equation of line given slope and one point is given as :

[tex]y - y_{1} = m ( x - x_{1} )[/tex]

[tex]x_{1}[/tex] = 1

[tex]y_{1}[/tex] = 7

[tex]m = -2[/tex]

substituting the values into the equation , we have :

[tex]y - 7 = -2 ( x - 1 )[/tex]

[tex]y - 7 = -2x +2[/tex]

[tex]y = -2x + 2 + 7[/tex]

[tex]y = -2x + 9[/tex]

Answer:

27.83

Step-by-step explanation:.15(24.20)=3.63

3.63+24.20+27.83

To calculate a 15% tip on a $24.20 bill, convert 15% to a decimal (0.15), and multiply this by the total bill. The tip should be $3.63.

The concept behind leaving a tip is to provide payment that is a certain percentage of the total bill. In your query, you want to leave a 15% tip on a bill of $24.20. To figure out how much the tip would be, you would multiply the total bill by the tip percentage.

First, you need to convert the tip percentage into a decimal form. To do that, you divide the percentage by 100. So 15 divided by 100 is 0.15.

Next, you multiply the total bill by this decimal. In this case, 24.2 (the total bill) multiplied by 0.15 equals 3.63. Thus, the tip they should leave is $3.63.

So the numbers must be 4, and 7.

Using the Segment Addition Postulate, we determined that the length of segment EH is 20 units, given the lengths of segments EG, FG, and FH in the figure.

In the given figure, we have three points E, F, G, and H, with F being between E and G, and G being between F and H. We are given the lengths of line segments EG, FG, and FH, and we need to find the length of segment EH.

To find EH, we can use the Segment Addition Postulate, which states that for three collinear points, if one point is between the other two, then the sum of the lengths of the two smaller segments is equal to the length of the larger segment.

In this case, we have:

EG + GF = EF

Given that EG is 10 and GF is 2:

10 + 2 = EF

12 = EF

Now, we know the length of segment EF is 12. Next, we can apply the same principle to segments EF and FH:

EF + FH = EH

Substituting the values:

12 + 8 = EH

20 = EH

So, the length of segment EH is 20 units.

Answer:

length of longer piece = 18 m

Step-by-step explanation:

Timothy had 24 meters of ribbon

shorter piece is 6 meters

longer piece = actual piece - shorter piece

                      = 24 - 6

                      = 18 m

Final answer:

The longer piece of ribbon is 18 meters long, which is obtained by subtracting the length of the shorter piece from the total length of the ribbon.

Explanation:

Timothy started with a 24-meter long ribbon and cut it into two pieces, with the shorter piece being 6 meters in length. To find the length of the longer piece, we subtract the length of the shorter piece from the total length of the ribbon.

Length of the longer piece = Total length of the ribbon - Length of the shorter piece

Length of the longer piece = 24 meters - 6 meters = 18 meters.

Therefore, the longer piece of ribbon is 18 meters long.

12

=-2

3

The student needs to evaluate H(-1) for a given function. Based on the information, h(x) = 4x + x² seems like the function intended, thus h(-1) equals -3.

The student is asking to evaluate the function H(x) at x = -1. From the information given, it seems there is a typo in the function H(x), but we can still proceed with the information from the examples provided.

The correct expression for H(x) based on the examples might be h(x) = 4x + x². When evaluating h(-1), the calculation would be h(-1) = 4(-1) + (-1)².

Using order of operations:

Now, sum both results: -4 + 1 = -3.

Therefore, the value of H(-1) or h(-1) is -3.

Sixty-one one hundredths

Final answer:

The fraction of a dollar that 61 pennies represent is 61/100, which in decimal form is 0.61, and in word form is sixty-one hundredths.

Explanation:

If we want to express 61 pennies as a fraction of a dollar, we simply divide the number of pennies by the total number of pennies in a dollar. Since there are 100 pennies in a dollar, we get the fraction 61/100.

In decimal form, this fraction is equivalent to 0.61 because when you divide the numerator 61 by the denominator 100, the result is 0.61. Converting this fraction into words, we say sixty-one hundredths.

Using money examples, like fractions of a dollar, helps make the math more relatable as we often work with money in everyday life.
