What is the 325th Triangular number?
Answer:52813
Step-by-step explanation:
To get the 325th triangular number all you have to do is n x (n+1) /2
N=325
325 x 325+1
325x325=105625
105625+1=105626
105626/2=52813
There you go=52813 is the 325th triangular number
Which equation shows an example of the associative property of addition?
A. (–4 + i) + 4i = –4 + (i + 4i)
B. (–4 + i) + 4i = 4i + (–4i + i)
C. 4i × (–4i + i) = (4i – 4i) + (4i × i)
D. (–4i + i) + 0 = (–4i + i)
Answer:
I am pretty it's A
Step-by-step explanation:
Basically the Associative Law of Addition means that the order that the numbers are added does not matter.
Answer:
A. (–4 + i) + 4i = –4 + (i + 4i)

Jordan has 3 blue shirts, 4 red shirts and 6 orange shirts. She chooses a shirt for Monday and places it in her suitcase. Then, she chooses a shirt for Tuesday. What is the probability that she choose a red shirt for Monday and an orange shirt for Tuesday?
Answer:
30% on Monday 46% on Tuesday
Step-by-step explanation:
Well you have 3 blue shirts 4 red shirts and 6 orange shirts so what you have to do is add all them together to make it a fraction which you would do 3+4+6 which is 13/13 so the probability of her wearing a red shirt on Monday would be 4/13 since there are 4 red shirts and 13 in total so we make 4/13 as a fraction which would give us 30% chance she would choose a red shirt on Monday and for Tuesday we do the same thing but instead we use orange shirts so which is 6/13 which would give her a percentage of 46% on Tuesday it's more closer to half than the red shirts because 6 pretty much half of 13 but since 13 is a odd number it isn't half because half of 13 is 6.5

10. You want to be able to withdraw $30,000 each year for 25 years. Your account earns 8% interest. a. How much do you need in your account at the beginning? b. How much total money will you pull out of the account? c. How much of that money is interest?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Rate (r) = 8% =. 0.08
Period (t) = 25 years
Yearly withdrawal = cashflow = P= $30,000
Using the present value formula (PV) :
Present Value (PV) = P[(1 - (1 + r)^-n) / r]
PV = 30000((1 - (1 + 0.08)^-25) / 0.08)
PV = $320,243.29
B.) Total amount pulled out :
Yearly withdrawal * number of years
$25000 * 25 = 625,000
C.)
Interest :
$625000 - $320,243.29 = $304,756.71

Answer:
problem 1: h=a/b problem 2: 5
Step-by-step explanation:
First problem: a=bh
First you have to flip the equation so bh=a
Next you have to divide both sides by b.
bh/b=a/b
so h=a/b
Second problem: 45ft is the area and 9ft is the base so to find the height you have to divide the area by the base
If you only have the base and height you would multiply them to find the area. If you only have area and height you divide area by height to get base.
You have to divide 45 by 9, the answer would be 5.
Hope this helped!

Determine the measure of ∠Q, rounded to the nearest tenth of a degree.
images attached.
Answer:
D
Step-by-step explanation:
Using the Sine rule in Δ QRS , that is
[tex]\frac{q}{sinQ}[/tex] = [tex]\frac{r}{sinR}[/tex] , that is
[tex]\frac{15}{sinQ}[/tex] = [tex]\frac{12}{sin50.1}[/tex] ( cross- multiply )
12× sinQ = 15 × sin50.1° ( divide both sides by 12 )
sinQ = [tex]\frac{15sin50.1}{12}[/tex] , thus
Q = [tex]sin^{-1}[/tex] ( [tex]\frac{15sin50.1}{12}[/tex] ) ≈ 73.5° ( to the nearest tenth )

There are 28 roses and 35 carnations. Anna is making flower arrangements using both flowers, what is the maximum number of arrangements she could make?
Answer:
The maximum amount of flower arrangements she can make are 28.
Step-by-step explanation:
There are enough roses and carnations to make 28 flower arrangements. There will still be leftover carnations but that's fine.
You do this by finding the smaller number of flowers and grouping them with the other flower so it makes a group of two. If the other flower had 2x the amount of the smaller flower, them group them in a group of 3; 1 : 2
But this is only used to make the maximum amount. this is not the efficient way to go but this is the way to go if you are finding the max amount.
Need Help with 44.. picture above
Answer:
Ok:
Step-by-step explanation:
I see that you set up 90 miles = 60 mph * t, where you found out that t = 1.5. What what you needed to do was set 180 miles = 45 mph * t. This is because it is 45 mph for the whole trip. Then, you find that t = 4 hours. That that means that he spent 2.5 hours driving back. Then, we can do d=vt and find 90/2.5 as the speed he went home at. Which comes out to be 36 mph.
An online furniture store sells chairs for $100 each and tables for $450 each. Every day, the store can ship a maximum of 24 pieces of furniture and must sell no less than $4500 worth of chairs and tables. If 5 tables were sold, determine all possible values for the number of chairs that the store must sell in order to meet the requirements.
Answer:
Actually, there is no answer to this problem.
450x5=2250
4500-2250=2250
2250/100=22.5
Technically the "answer" to this would be 23 or more, but the problem is saying the MAXIMUM amount they can ship is 24
23+5=28
28 is larger than 24, meaning there is no answer to the problem.
There is no answer to this problem.
What is inequality?An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value.
Given that, an online furniture store sells chairs for $100 each and tables for $450 each. Every day, the store can ship a maximum of 24 pieces of furniture and must sell no less than $4500 worth of chairs and tables and 5 tables are sold,
According to question,
450*5 = 2250
4500 - 2250 = 2250
Since, each chair is sold for $100, therefore,
2250/100 = 22.5
≈ 23
Since, 5 tables are already sold,
23 + 5 = 28
This is a contradiction to the given conditions, because the problem is saying the maximum amount they can ship is 24 and 28 is larger than 24.
Hence, there is no answer to the problem.
