If you triple 4 and subtract to each day how many days until you have zero

1 answer:

5 0

Do you mean subtract two each day? If so...
4x3=12 and 12 divided by 2 is 6 so it would take six days to reach zero
or
you could manually subtract two from 6 each days as in 12-2=10 (1 day), 10-2=8 (2 days), and so on...

A population numbers 508 organisms initially and increases by 6.2% each year.

IceJOKER [234]

To find the population after t number of years, multiply the starting population by 1 plus the percent increase raised to the number of years.

The equation would be: P = 508(1.062)^t

At big bens bakery 48 chocolate donuts were made,which is 6 times the number of cream filled donuts made.How many more chocolate

ratelena [41]

Answer:

The number of chocolate made donuts is 40 more than cream filed donuts

Step-by-step explanation:

Given as :

The number of chocolate donuts made = 48

The number of chocolate donuts is 6 times the number of cream filled donuts

So, Let the number of cream filled donuts = x

So, number of chocolate donuts made = $6\times x$

∴ $6\times x$ = 48

Or, x = $\frac{48}{6}$ = 8

So, the number of cream filled donuts = 8

Now ,

The number of chocolate donuts made - the number of cream filled donuts = 48 - 8 = 40

So , The number of chocolate made donuts is 40 more than cream filed donuts Answer

Storing milk at temperatures colder than 35°F can affect its quality of taste. However, storing milk at temperatures warmer than

puteri [66]

t > 35 and t <40

So, Option A is correct.

Step-by-step explanation:

This is the question of compound inequality

Since the temperature of milk should be greater than 35 and the temperature should be less than 40 for keeping the quality of milk.

So, Representing it in inequality the union of both conditions we get:

t > 35 and t <40

So, Option A is correct.

The ages of students in a school are normally distributed with a mean of 15 years and a standard deviation of 2 years. Approxima

worty [1.4K]

We have been given that the ages of students in a school are normally distributed with a mean of 15 years and a standard deviation of 2 years.

We are asked to find the percentage of students that are between 14 and 18 years old.

First of all, we will find z-score corresponding to 14 and 18 using z-score formula.

$z=\frac{x-\mu}{\sigma}$

$z=\frac{14-15}{2}$

$z=\frac{-1}{2}$

$z=-0.5$

Similarly, we will find the z-score corresponding to 18.

$z=\frac{18-15}{2}$

$z=\frac{3}{2}$

$z=1.5$

Now we will find the probability of getting a z-score between $-0.5$ and $1.5$ that is $P(-0.5$ .

$P(-0.5$

Using normal distribution table, we will get:

$P(-0.5$

Let us convert $0.62465$ into percentage.

$0.62465\times 100\%=62.465\%\approx 62.5\%$

Therefore, approximately $62.5\%$ of the students are between 14 and 18 years old.
