Answer:

0.25 x 20 = 5

<h3>Step-by-step explanation:</h3>

To make it easier we can make the decimal 0.25 into the fraction 1/4. In this case, we would also make 20 into a fraction. Which would give us 20/1. Now we would multiply the numerators (1 and 20) together and we get 20. Then we would multiply the denominators (4 and 1) to get 4. From there we can write the fraction (or the division problem) as 20/4. We can divide both sides by four to get 5/1. Which gets us our answer of 5.

In a lab, a scientist is growing bacteria for a study. The scientist begins with a bacteria

Diano4ka-milaya [45]

Answer:

The answer is below

Step-by-step explanation:

The growth of the bacteria is in the form of an exponential growth. It is given by the formula:

$P(t)=ae^{rt}\\\\where\ t\ is\ the\ number\ of \ hours, P(t)\ is\ the \ population\ at\ t\ hours\\\and\ a=population\ at\ start$

At 2 hours, the population is 62 cells, hence:

$P(2)=ae^{2r}\\\\62=ae^{2r}\ \ .\ \ .\ \ .\ (1)$

After another 2 hours (4 hours), the population is 1 million:

$P(4)=ae^{4r}\\\\1000000=ae^{4r}\ \ .\ \ .\ \ .\ (2)\\\\Divide \ equation\ 2\ by\ equation\ 1:\\\\\frac{1000000}{62}=\frac{ae^{4r}}{ae^{2r}} \\\\16129=e^{2r}\\\\ln(e^{2r})=ln(16129)\\\\2r=9.688\\\\r=4.844$

Put r = 4.844 in equation 1

$62=ae^{2*4.844}\\\\62=16129a\\\\a=0.003844$

$P(t)=0.003844e^{4.844t}\\\\at \ start,t=0\\\\P(0)=0.003844$

monique has 3/4 of tissues. if she cuts half of those tissues how much did she cut? put the answer in a fraction and percentage(

skelet666 [1.2K]

The required fraction of the tissue she cut is 3 /8, and the percentage is 37.5%.

Given that,
Monique has 3/4 of tissues. she cuts half of those tissues

<h3>What is the fraction?</h3>

Fraction is defined as the number of compositions that constitute the Whole.

Here,
Let the number of tissue be x,
She has 3 / 4 of the tissues = 3 / 4 x
she cuts half of those tissues = 1 / 2 * 3 / 4 * x
= 3/8x or 37.5% of x

Thus, the required fraction of the tissue she cut is 3 /8, and the percentage is 37.5%.

Claudio needs to buy gifts for 8 friends. He wants to give the same gift to all his friends and he plans to have the gifts wrapp

Blizzard [7]

Answer:

7.25

Step-by-step explanation:

In the question, the term at least means less than or equal to is represented by ≥

Let the cost of each gift = c

He is buying gifts for 8 friends = 8 gifts

Hence, our Inequality equation is written as:

(c + $1.50)× 8 ≥ $70

8c + 12 ≥ 70

8c ≥70 - 12

c ≥ 58/8

c≥ 7.25

Therefore, the amount Claudio needs to spend on each gift in order to receive free shipping is 7.25
