The product of all digits of positive integer M is 105. How many such Ms are there with distinct digits?
Answer:
6
Step-by-step explanation:
105 is a composite number (not prime). If you decompose 105 into its prime factors (see attached image), you get 105 = 3 x 5 x 7. This means that the product 105 can only be written this way; any other way, for example 15 x 7 would not use numbers that are single digits.
The question boils down to how many ways the digits 3, 5, 7 can be arranged, using each digit exactly once.
That's a permutation problem, and it can be answered easily by thinking this way: given the digits 3, 5, 7, there are 3 choices for the first digit, then 2 for the second digit (for EACH of the first choices), then only 1 choice for the final digit.
3 x 2 x 1 = 6 ways that 3, 5, 7 can be arranged to make a 3-digit number. Here they are:
357, 375, 537, 573, 735, 753

What is the Volume of a hexagonal pyramid shown if the hexagon has a side length of 4 inches and the height of the pyramid is 12 inches?
Answer:
166.24 in³Step-by-step explanation:
Volume formula:
V = 1/3 Bh, B-base area, h- heightBase area:
B = 3√3a² / 2 = 3√3*4² / 2 = 41.57 in (rounded)Volume:
V = 1/3*41.56*12 = 166.24 in³A construction worker drops a wrench from a height of 484 feel the function
h =
16x
+ 484 gives the height h of the wrench after a seconds When does the wrench hit the ground?
The wrench hits the ground blank
seconds after it is dropped
Answer:
30.25 seconds
Step-by-step explanation:
If you want to find the time at which the wrench hits the ground, you must recognize that the height of the wrench is 0 feet. If h represents the height, then 0 can be plugged in for h. The equation is now 0=16x+484. You then must subtract 484 from both sides, giving you -484=16x. You then divide both sides by 16 to give you x by itself. -484/16=-30.25. Because this is dealing with time and negative time does not exist, the negative sign on the 30.25 can be neglected.

You are paying off a student loan in monthly installments. After
the 4rd payment the remaining balance is $13,900. After the 5th
payment your remaining balance is $13,500. If n is the number of
payments that have been made, what is the nth term rule?
Answer:
The loan will be paid after 39 monthly installments.
Step-by-step explanation:
Since I am paying off a student loan in monthly installments, and after the 4th payment the remaining balance is $ 13,900, while after the 5th payment my remaining balance is $ 13,500, to determine the amount of payments in which the loan was agreed I must perform the following calculation:
13900 - 13500 = 400
400 x 5 = 2000
2000 + 13500 = 15500
15500/400 = 38.75
Thus, the loan will be paid after 39 monthly installments.
Colton sold a total of 28 tee shirts and sweatshirts as a fundraiser for his football team. If tee shirts cost 12 dollars each and sweatshirts cost 20 dollars each and he raised a total of 424 dollars how many tee shirts did he sell?
Answer:
11 sweatshirts and 17 t shirts
Step-by-step explanation:
[tex]t + s = 28\\12t = 20s = 424[/tex]
Step one: cancel out one variable. In this one, t.
[tex]-12(t + s = 28)\\-12t -12s =-336[/tex]
Now that we have that, subtract that from the other expression.
[tex]12t + 20s = 424\\-12t -12s = 336[/tex]
You should get:
[tex]8s = 88\\ s = 11[/tex]
Plug s in any expression
[tex]t + 11 = 28[/tex]
You should know where to go from there, I'm lazy :p
Then t = 17

Nevada has the fastest growing population according to the U.S. Census bureau. In 2004, the population of Nevada was 2.62 million and increasing at an annual rate of 3.5%. What is the expected population 2010 ? Apply the population growth formula N=Noe^rt
Answer:
32,322,237 million or 3.23million
Step-by-step explanation:
Nevada has the fastest-growing population according to the U.S. Census bureau. In 2004, the population of Nevada was 2.62 million and increasing at an annual rate of 3.5%. What is the expected population in 2010? Apply the population growth formula N=Noe^rt
Applying the formula given above
N=Noe^rt
No = 2.62 million
r = 3.5% = 0.035
t = 2010 - 2004 = 6 years
N = 2.62 × e^6 × 0.035
N = 3.2322365171 million
= 32,322,237 millon
Approximately = 3.23 millon

How might doing math slowly help with problems that are difficult to understand or hard to solve?
Q: How might doing math slowly help with problems that are difficult to understand or hard to solve?
A: It calms you down. When you are stressed, you are most likely to get it wrong because you are panicking. This also helps because you can read the problem correctly and make sure you are doing it right, because in math, If you get 1 small thing wrong, you usually get the entire thing wrong.

The endpoints of the directed line segment AB are A(−3, 4) and B(5, 10). Find the coordinates of point P along AB¯¯¯¯¯¯¯¯ so that the ratio of AP to PB is 1 to 3.
Answer:
The coordinates of P is (-1,5.5)
Step-by-step explanation:
Here, we want to find the coordinates of the point that divides the segment into the ratio 1 to 3
To do this, we are going to use the section formula
We have this as;
(x,y) = (nx1 + mx2)/m+ n, (ny1 + my2)/m + n
where m = 1 , n = 3
(x1,y1) = (-3,4)
(x2,y2) = (5,10)
Substituting these values, we have;
(x,y) = (3(-3) + 1(5)/4 , (3(4) + 1(10)/4
(x,y) = (-9+ 5)/4 , (12 + 10)/4
(x,y) = (-1, 5.5)
A statue of George Washington is also in Druid Hill Park. If a girl stands 15 m away from the statue, and places a mirror 12 m from the statue (3 m from her feet), she can see the top of the statue in the mirror. The girl's height is 5.5 ft. How tall is the statue?
Answer:
The statue is 22ft tall.
Step-by-step explanation:
Here we will have two similar triangle rectangles.
One is made between the girl's feet, the mirror, and the girl's eyes.
So in this case the catheti are:
the distance between the girl and the mirror (3 m) and the height of the girl (5.5 ft)
The other triangle rectangle has the vertices:
The mirror, the base of the statue, and the top of the statue.
Such that the catheti of this triangle are the distance between the base of the statue and the mirror (12m) and the height of the statue (we want to know this, let's call this X for the moment).
Because the triangles are similar, this means that there is a proportionality constant between each correspondent side, let's call this k.
Then the distance between the girl and the mirror must be k times the distance between the base of the statue and the mirror:
3m = k*12m
And the height of the girl must be k times the height of the statue.
5.5ft = k*X
You can see that we have different units, this does not matter because k is a dimensionless constant.
With the first equation we can find the value of k
3m = k*12m
3m/12m = k
(3/12) = 1/4 = k
Now we can replace this in the other equation to get:
5.5ft = (1/4)*X
Solving this for X we get:
(5.5ft)*4 = X
22ft = X
The height of the statue is 22ft.
