Find the coefficient of the t4
term in the expansion of
(4t– 3)^5
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

Nat had some stamps. He divided them into sets
of six to put in his album. He made 17 sets. How
many stamps did Nat have?
Answer:
102
Step-by-step explanation:
Nat had a total of 102 stamps which he divided into 17 sets. Each set contained six stamps.
To find out how many stamps Nat had, we need to multiply the number of sets by the number of stamps per set. Nat divided his stamps into sets of six. He made 17 sets. To calculate the total number of stamps, we perform the multiplication:
Multiply the number of stamps in each set (6) by the number of sets (17).
6 stamps/set × 17 sets = 102 stamps
Hence, Nat had 102 stamps in total.

10. There are 100 pennies in a dollar. What
fraction of a dollar is 61 pennies? Write it as a
fraction, as a decimal, and in word form.
How do you put 61/100 in word form
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.
A bicycle wheel travels 26π in. for each revolution. What is the radius of the wheel?
Answer:
13
Step-by-step explanation:
Circumference=2πr
2πr=26π
2r=26
r=13
Final answer:
The radius of a bicycle wheel that travels 26π inches per revolution is found using the circumference formula. By solving 26π = 2πr, the radius is determined to be 13 inches.
Explanation:
The question asks to determine the radius of a bicycle wheel that travels 26π inches per revolution. To find the radius, we can use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference and r is the radius. Since we know the wheel travels 26π inches for each revolution, this distance is the circumference of the wheel.
Setting up the equation 26π = 2πr, we can solve for the radius r by dividing both sides of the equation by 2π:
26π = 2πrr = (26π) / (2π)r = 26 / 2r = 13 inchesThe radius of the bicycle wheel is 13 inches.
In the figure below, F is between E and G, and G is between F and H. IF EG-10, FG-2, and FH-8, find EH
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:
(a) 4x=5(x-18)
(b) ∠A=∠B=360°
Step-by-step explanation:
Corresponding angles : when two lines are crossed by a transversal , the angle in matching corners are called corresponding angles.
Since the corresponding are congruent.
Therefore,
∠A=∠B
⇔4x=5(x-18)
⇔4x=5x-90
⇔4x-5x=-90
⇔-x=-90
⇔x=90
Therefore ∠A=∠B= 4×90°=360°

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.
Explanation: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:
4(-1) = -4(-1)² = 1Now, sum both results: -4 + 1 = -3.
Therefore, the value of H(-1) or h(-1) is -3.

The group wants to leave a 15% tip and the bill 24.20 how much do they leave
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.
Explanation: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.

Three friends ordered 2 pizzas.Each pizza was cut into 8 slices. If each person ate the same amount of slices, how many slices did each person eat?
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.
Total number of slices: 2 pizzas x 8 slices per pizza = 16 slicesNumber of friends: 3Slices per person: 16 slices \/ 3 friends = 5 and 1/3 slices per personSince 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.
Timothy had 24 meters of ribbon. He cuts it into 2 pieces. The shorter piece is 6 meters long. What is the length of the longer piece?
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.

Find the value of two numbers if their sum is 11 and their difference is 3
Answer:
4+7=11
7-4=3
So the numbers must be 4, and 7.
The sum of two numbers is 21,and their difference is 9
Answer:
The numbers are 15 and 6.
Step-by-step explanation:
We can solve the problem algebraically (using equations). First, write equations that represent the situation.
Choose variables to represent the numbers:
let the numbers be "x" and "y"
Take apart each section of the problem and make an equation.
"The sum of two numbers is 21"
x + y = 21 Sum means the answer when you add numbers
"Their difference is 9"
x - y = 9 Difference means the answer when you subtract numbers
Using the two equations, you can solve using elimination. With this method, you get rid of one of the variables, so you can easily solve for the other one. You can use elimination when one of your variables have the same variable number. Both equations have "1x" and "1y" ("1" is never written).
Add the equations together by adding normally, with each of the terms with the same variable.
. x + y = 21 Add each term
+ x - y = 9 (x + x = 2x) (y + (-y) = 0) (21 + 9 = 30)
. 2x + 0 = 30 "y" variable cancelled out
. 2x = 30
. 2x/2 = 30/2 Divide both sides by "2" to isolate "x"
. x = 15 Answer for one number
To find the other number, substitute 'x' for 15 into one of the equations.
x + y = 21
15 + y = 21 Isolate "y" now
15 - 15 + y = 21 - 15 Subtract 15 from both sides
y = 21 - 15 15-15 cancelled out on the left side. Solve right side.
y = 6 Answer for second number
Therefore the two numbers are 15 and 6.
