Whst is 15 divided by 6 2/3 equals

Answers

First you make 15 a fraction by putting it over 1.
Then you make 6 2/3 a mixed fraction.
To do this, you multiply 6 with 3 and add 2 to it. Then you put the number over 3.
We get
6 X 3 = 18
18 +2 = 20
20/3

Now, we divide 15/1 with 20/3.
When we divide it, we actually cross multiply it. Basically, we flip the fraction and multiply it.

So we get 15/1 X 3/20 = $(15 X 3)/(1 X 20)$ .

We get 45/20 which can be simplified to 9/5 which can be simplified to 2 1/4.

So the answer is 9/4 or 2 1/4.

If you would like to know what is 15 divided by 6 2/3, you can calculate this using the following steps:

6 2/3 = 20/3

15 / 20/3 = 15 * 3/20 = 45/20 = 9/4 = 2.25

Result: 15 divided by 6 2/3 equals to 9/4.

Earlier this year in a drug bust in Shanghi, China, police seized 2.4 tons of methamphetamines. If a typical dosage is 50mg, how many doses is that bust, which the Chinese police prevented from being sold to the public?

Answers

2.4 tons=2.4 tons*(1,000 Kg / 1ton)*(1,000,000 mg / 1 kg)=
=2,400,000,000 mg=2.4 x 10⁹ mg

Now, we solve this problem by the rule of three.

50 mg ---------------------1dose
2.4x10⁹ mg---------------- x

x=(2.4 x 10⁹ mg * 1 dose) / 50 mg=48,000,000 doses.

Answer: 48,000,000 doses

Nathan has 80 stamps in his collection. He adds 1 stamp to it today. Each day he plans to add twice the number of stamps as the previous day. If he keeps adding stamps at this rate for n days, which recursive function represents the number of stamps he has on any day in the future?

Answers

The recursive function which represents the number of stamps he has on any day in the future is F(n) = 80 + 2ⁿ.

Given that:

Number of stamps that Nathan has in the beginning = 80

He adds 1 stamp to it today.

Each day he plans to add twice the number of stamps as the previous day.

So, the number of stamps will be in the order:

80 + 1, 80 + 2(1), 80 + 2(2(1)), 80 + 2(2(2(1))), ...

That is each day, the added stamps become twice.

On the first day, he added 1, on the second day, he added 2, on the third day, he added 4, ...

So, the recursive function can be written as:

F(n) = 80 + 2ⁿ, where n starts from 0.

We start with 80 and we add 1 on the first day, 2 on the 2nd, 4 on the 3rd, etc.. Looking at the numbers being added 1 = 202 = 214 = 228 = 2316 = 24...We start with 80 and we add 2n to it where n represents the number of days into the iterationwith n starting at 0 The function that shows how many stamps we have on any given day is DS = 80 + ∑ 2n Where D is the number of days we are into the iteration n=0NOTE: This starts at day 0 which would be S = 80 + 20 = 80 + 1 = 81 stamps Example: To find how many stamps we have on D = 4 we would haveS = 80+20+21+22+23+24 = 80+1+2+4+ 8+16 = 111 stamps

In a certain county, the number of charter schools is 6 less than twice the number of alternative schools. We know that there are 52 charter schools in the county. How many alternative schools are in the county?

Answers

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

So, 52 charter schools and the number is 6 less than the alternative schools doubled. In order to find the number of alternative schools, we need to reverse the equation. 52+6=58. That means 58 is twice the amount of alternative schools. 58/2 equals 29, therefore the answer is 29
