There are 48 students in a school band. The ratio of girls to boys is 5:7. How many girls are in the band? How many boys are in the band?

Answers

Answer 1
step by step explanation:
5:7
= 5+7 = 12
48 ÷ 12 = 4
1 part of ratio = 4
4 x 7 = 28
so there are 28 boys.
Answer 2

Answer:

The number of boys is 20 and the number of girls is 28

Step-by-step explanation:

5+7= 12  that means 5/12 students are boys, while 7/12 students are girls

Boys: (5/12)48= 20

Girls: (7/12)48= 28

The number of bacteria at the beginning of an experiment was 30 and the bacteria grow at an hourly rate of 1.4 percent. Using the model given by () = 0e, estimate the number of bacteria, rounded to the nearest whole number after 20 hours.

Answers

Answer:

The estimated number of bacteria after 20 hours is 40.

Step-by-step explanation:

This is a case where a geometrical progression is reported, which is a particular case of exponential growth and is defined by the following formula:

[tex]n(t) = n_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex] (1)

Where:

[tex]n_{o}[/tex] - Initial number of bacteria, dimensionless.

[tex]r[/tex] - Increase growth of the experiment, expressed in percentage.

[tex]t[/tex] - Time, measured in hours.

[tex]n(t)[/tex] - Current number of bacteria, dimensionless.

If we know that [tex]n_{o} = 30[/tex], [tex]r = 1.4[/tex] and [tex]t = 20\,h[/tex], then the number of bacteria after 20 hours is:

[tex]n(t) = 30\cdot \left(1+\frac{1.4}{100} \right)^{20}[/tex]

[tex]n(t) \approx 39.616[/tex]

[tex]n(t) = 40[/tex]

The estimated number of bacteria after 20 hours is 40.

What is 956.3 written in scientific notation?

Answers

You can write it as
9.563 * 10^2

The decimal number that is multiplied by 10 must be less than a two-digit number.

We move the decimal point to the left for this problem and stop where the decimal is less than a two-digit number.

So, 956.3 becomes 9.56 after moving two places to the left. Moving to the left makes the exponent of 10 positive. Moving to the right, makes the exponent of 10 negative.

We want our answer in the form

(decimal number) x 10^(n).

Answer: 9.56 x 10^2

You can buy 5 cans of green beans at the village market for $2.30, or you can buy 10 of them at Best Food for $5.10. Which place is the better buy?​

Answers

Answer:

The village market

Step-by-step explanation:

Price per can at the village market

= 2.30÷5

= $0.46

Price per can at Best Food

=5.10÷10

= $0.51

Answer:

Village market

Step-by-step explanation:

Find the unit rate at village market and Best food and compare.

Village market:

Rate per can  = 2.30 ÷ 5

                      = $ 0.46

Best food:

Rate per can = 5.10 ÷ 10

                     = 0.51

0.46 < 0.51

Buying can from village market is best buy as that is less priced

Now Napoleon's France followed in the footsteps of the English.Napoleon's 35,000-man army was led by his brother-in-law and soon scored an amazing success: They captured Toussaint in 1802 and brought him to France, where he died in prison in 1803. But the former slaves fought on. In two years of fighting, nearly 50,000 French soldiers died. And on January 1, 1804, the victorious Republic of Haiti was born. Fighting for freedom, the former slaves defeated the armies of first England, then France: Europe's two most powerful nations.Haiti was born free; human rights won over property rights.In 1807 a bill to ban all English involvement in slave trading passed the House of Commons, then the House of Lords. At precisely noon on March 25, King George III signed the law. We should mark that date, honor it, to this day. For while no slaves were freed by the bill, it marked a great change in the world. More slaves from Africa had been shipped by the British than by any other nation. That part of the grim history of sugar and slavery was over. Indeed, that very same year Congress passed a law forbidding Americans from being involved in importing slaves. In the great contest over whether a human, any human, could ever be property; the tide was turning.How do the authors develop the claim in the two passages?Both passages help the reader understand how the end of involuntary servitude in Haiti led to the end of involuntary servitude in Britain.Both passages illustrate how property rights were more important to the British than to Americans.Both passages support the claim that human rights became more important than property rights in the early 1800s.Both passages support the claim that the end of the slave trade eventually led to the end of the sugar industry.
