Answer:
Approximately 53
Step-by-step explanation:
This is a geometric progression, because each term is found by multiplying the previous one by a constant factor.
In our case, the first term is know (a1 = 3), and the growth factor is also known (q = 1.333333).
What we are tasked to do is to find the 11th (n=11) term of the series, since it asks for AFTER the 10th roll.. That's easy with the base formula:
[tex]a_{n} = a_{1} q^{n-1}[/tex]
Let's place the values we have in the equation and solve it:
[tex]a_{10} = 3 * (1.333333)^{11-1} = 3 * (17.758) = 53.3[/tex]
So, after the 10th roll, you should need 53 dice, approximately.

Answer:
21.4
Answer:
x = 21.44506921
Step-by-step explanation:
Trigonometry
We need to find x or the adjacent
We are given the Opposite ( 10 )
We don't need the hypotenuse
So we use our formula triangles
TOA SOH CAH
Since we don't need the hypotenuse, we look for a formula without ' H ' in it and it is TOA so we use it
Tan = Opposite ÷ Adjacent
We need to find the adjacent so we rearrange the formula into
Adjacent = Opposite ÷ Tan
Adjacent = 10 ÷ tan(25)
Adjacent = 21.44506921

Dahlia is trying to decide which bank she should use for a loan she wants to take out. In either case, the principal of the loan will be $19,450, and Dahlia will make monthly payments. Bank P offers a nine-year loan with an interest rate of 5.8%, compounded monthly, and assesses a service charge of $925.00. Bank Q offers a ten-year loan with an interest rate of 5.5%, compounded monthly, and assesses a service charge of $690.85. Which loan will have the greater total finance charge, and how much greater will it be? Round all dollar values to the nearest cent.
It is computed that loan Q's finance charge will be $83.73 greater than loan P's.
How to compute the loan?From the information, the payment for bank P will be:
= (0.058/12)(19450) / [1 - (1 + 0.058/12)^108
= 231.59
The future value will be:
= 231.59 × 12 × 9
= 25011.72
The finance charge for P will be:
= (25011.72 - 19450) + 925
= 6846.72
The payment for Q is 211.08. The future value will be:
= 211.08 × 12 × 10
= 25329.60
The finance charge for Q will be:
= (25329.60 - 19450) + 690.85
= 6570.45.
The difference will now be:
= 6570.45 - 6846.72
= $83.73

Quiana took out a loan to pay for a new car. Initially, she owed the lender $15,234.68. She has repaid $247.43 of the loan each month for the past 5 months. What is the net change to the loan from Quiana’s perspective over the past 5 months?
Complete the steps below to help Quiana calculate the loan amount that she’s repaid to the lender.
Part A
Write a rational number to express the initial loan amount as it relates to Quiana’s bank account.
Answer:
$13,997.53
Step-by-step explanation:
The simplest, minimally acceptable answer would stem from multiplying by 5 the $247.43 monthly payment and subtracting the result from the amount initially owed:
$15,234.68
-$ 1,237.15
----------------
$13,997.53
To calculate the net change to the loan from Quiana's perspective over the past 5 months, subtract the total amount she has repaid from the initial loan amount. In this case, the net change is $13,997.53.
Explanation:The amount owed to the lender = $15,234.68
Amount repaid = $247.43
Time = 5 months
To calculate the net change to the loan from Quiana's perspective over the past 5 months, we need to subtract the total amount she has repaid from the initial loan amount.
Since she repaid $247.43 each month for 5 months, the total amount repaid is $247.43 x 5 = $1237.15.
To find the net change to the loan, we subtract the total amount repaid from the initial loan amount:
= $15,234.68 - $1237.15
= $13,997.53.

You are try to dunk a basketball. You need to jump 2.5 feet in the air to dunk the ball. The height that your feet need to be of the ground is given by the function h(t)= _ 16t2+12r. What is the maximum height your feet will be above the ground? Will you be able to dunk the ball?
Answer:
1)he maximum height your feet will be above the ground is 2.25
2)Will you be able to dunk the ball= No
Step-by-step explanation:
Given:
In order to dunk the basket ball, height needed to jump= 2.5 feet
The height that your feet need to be of the ground is given by the function h(t)= -16t^2+12t
1) the maximum height your feet will be above the ground=?
Given function of height,h(x)=-16t^2+12t
finding maximun of the above function
The maximum of any function written in form of ax^2+bx+c is given by
max= c - (b2 / 4a)
Putting values c=0, b=12 and a=16, we get
max= 0-(12^2/4(-16))
= 144/64
=2.25 feet
he maximum height your feet will be above the ground is 2.25 feet.
2) Will you be able to dunk the ball=?
As the height needed to jump in the air to dunk the ball is 2.5 feet which is greater than the maximum height the feet will be above the ground i.e.
2.5>2.25
hence No you will not be able to dunk the ball !
The maximum height your feet will be above the ground is 2.25 feet. No, you will not be able to dunk the ball.
Explanation:To find the maximum height your feet will be above the ground, we need to determine the vertex of the quadratic function h(t) = -16t^2 + 12t.
The vertex of a quadratic function of the form h(t) = at^2 + bt + c is given by the formula t = -b/2a. In this case, a = -16 and b = 12, so the vertex is t = -12/(2*(-16)) = 0.375 seconds.
Substituting this value back into the function h(t), we get h(0.375) = -16(0.375)^2 + 12(0.375) = 2.25 feet. Therefore, the maximum height your feet will be above the ground is 2.25 feet.
Since you need to jump 2.5 feet in the air to dunk the ball and the maximum height your feet will reach is only 2.25 feet, you will not be able to dunk the ball.

A teacher is told he will have 20 students in his first-period class this year. He wants to predict the birthday month of his students, so he decides to run a simulation where January = 1, February = 2, etc. Use the simulated results to estimate the probability that a randomly picked student will have a September birthday.
9 6 5 8 9 2 4 10 9 7 2 10 12 6 9 2 9 11 1 3
Answer:
[tex]P = 0.25[/tex]
Step-by-step explanation:
The simulation shows a result composed of 20 data.
If January represents month 1 and February represents month 2 then September is represented by number 9.
According to this simulation, the probability of a randomly selected student having birthdays in September is:
[tex]P = \frac{X_9}{20}[/tex]
Where [tex]X_9[/tex] is the frequency of 9. That is, [tex]X_9[/tex] is the number of times the number 9 appears among the 20 data
Therefore:

Tameca already has a $55 dollars in her savings account. If she puts $5 per week in her account, write and solve an inequality to find out how many weeks she must save to have at least $100 in her account.
To find out how many weeks Tameca needs to save to have at least $100, we create an inequality, 5w + 55 >= 100, where 'w' represents the number of weeks. Solving this inequality gives w >= 9. Therefore, Tameca needs to save for at least 9 weeks.
Explanation:The subject of this problem is linear inequalities, which falls under Mathematics. To solve this problem, let's denote the number of weeks that Tameca needs to save money as 'w'. Since she already has $55 and is saving $5 each week, the inequality that represents this situation is 55 + 5w >= 100.
In order to solve this inequality, we need to isolate 'w'. You can do this by subtracting 55 from both sides of the inequality to get 5w >= 45. Then, divide both sides by 5 to get w >= 9.
Therefore, Tameca must save for at least 9 weeks in order to have a minimum of $100 in her savings account.

The length of a rectangular floor is 2 feet more than its width. The area of the floor is 168 square feet. Kim wants to use a rug in the middle of the room and leave a 2-foot border of the floor visible on all sides. What should the length (the shorter side) of the rug be
Answer:
8 ft
Step-by-step explanation:
let width = x
then length= x+2
Area = l(w)
=x(x+2)
168 = x^2 + 2x
x^2 + 2x-168=0
Using quadratic formula we get roots :
x= 12, x=-14
x= 12 (as width cannot be in negative)
then length= x+2 = 14
length of rug= length of floor - 4
= 14- 4
= 10
width of rug= width of floor- 4
= 12-4
= 8
Hence the length (the shorter side) of the rug be 8 feet !

Two brothers went shopping at a back-to-school sale where all shirts were the same price, and all the shorts too. The younger brother spent $79 on 4 new shirts and 3 pairs of shorts. The older brother purchased 7 new shirts and 8 pairs of shorts and paid a total of $185. How much did each item cost?
Each shirt cost $ ___ and each pair of shorts cost $ ___ .
Answer:
Shirts = $7
Shorts $17
Step-by-step explanation:
Let:
T - shirts
S - shorts
We can make two equations out of this problem:
4T + 3S = $79
7T + 8S = $185
Through substitution we can solve for one of the unknowns. We make one equation to solve for an unknown
[tex]4T+3S=\$79\\\\3S = \$79-4T\\\\S=\dfrac{\$79-4T}{3}[/tex]
We use the formula of S and insert it into the other equation:
[tex]7T+8(\dfrac{\$79-4T}{3}) = \$185\\\\7T + \dfrac{\$632-32T}{3}=\$185\\\\\dfrac{\$632-32T}{3}=\$185-7T\\\\\$632-32T=3(\$185-7T)\\\\$632-32T=\$555 - 21T\\\\-32T+21T=\$555-\$632\\\\-11T=-\$77\\\\\dfrac{-11T}{11}=\dfrac{-\$77}{11}\\\\T = \$7[/tex]
Thus T-shirts are $7 each.
Now that we know T, we can use it to solve for the other unknown. You can use it on any of the formulas.
[tex]4T+3S=\$79\\\\4(\$7) + 3S = \$79\\\\\$28+3S =\$79\\\\3S=\$79-\$28\\\\3S=\$51\\\\S=\dfrac{\$51}{3}\\\\S = \$17[/tex]
We know then that Shorts are $17 each.

Answer:
q(x)= 2x+5
r(x)= 6
Step-by-step explanation:
Given:
2x^2+13x+26 /x+4
Re-writing in the form of q(x) + r(x)/d(x)
Let
Polynomial P(x)= 2x^2+13x+26
Polynomial d(x)= x+4
Using remainder theorem, putting -4 in P(x) to find r(x)
P(-4)= 2(-4)^2+13(-4)+26
=6
i.e r(x)= 6
Finding q(x) by long division
q(x)= 2x+5
Hence given expression in the form q(x) + r(x)/d(x)
