Answer:

Y = X/5

Step-by-step explanation:

given

X : Y = 5 : 1

if we express this ratio in terms of fractions,

X/Y = 5/1 or ,

X/Y = 5 (multiply both sides of the equation by Y)

X = 5Y (Divide both sides by 5)

X/5 = Y (rearrange)

Y = X/5

You have to read 10 1/2 pages for homework. So far you have read 1/3 of the assignment. How many pages did you read

sladkih [1.3K]

Well, you have to read 10 1/2 pages and you have read 1/3 so ask your self...Self what is 1/3 of 10 1/2 pages. The key word of tells you to multiply the two numbers to find the answer. So $10\frac{1}{2} \times \frac{1}{3} = \frac{7}{2} = 3.5 pages$

Scientists have discovered a vaccine for a debilitating disease. This year there were 570,000 reported new cases of the disease

Ket [755]

Answer: There are approximately 853827 new cases in 6 years.

Step-by-step explanation:

Since we have given that

Initial population = 570000

Rate at which population decreases is given by

$\frac{2}{3}$

Now,

First year =570000

Second year is given by

$570000\times (\frac{1}{3})$

Third year is given by

$570000(\frac{1}{3})^2$

so, there is common ratio ,

it becomes geometric progression, as there is exponential decline.

so,

$570000,570000\times \frac{1}{3},570000\times( \frac{1}{3})^2,......,570000\times (\frac{1}{3})^6$

a=570000

common ratio is given by

$r=\frac{a_2}{a_1}=\frac{1}{3}$

number of terms = 6

Sum of terms will be given by

$S_n=\frac{a(1-r^n)}{(1-r)}$

We'll put this value in this formula,

$S_6=\frac{570000(1-(\frac{1}{3})^6}{(1-\frac{1}{3})}\\\\=853827.16$

So, there are approximately 853827 new cases in 6 years.
