A sum of money was shared among Daniel Elliot and frank in the ratio 5 : 7 : 8 . If frank shares was $2,781 more than Daniel sha

aliya0001 [1]

Answer:

$18,540

Step-by-step explanation:

To find the original sum of money shared, setting up two different proportions using the ratios and the amount given will help. For the first proportion, we can set 'x' equal to the amount of money that Daniel received. Since Frank received $2,781 more than this amount, his amount is the expression 'x + 2781'. Using equivalent ratios, we can set up the following proportion:

$\frac{Frank}{Daniel}=\frac{8}{5}=\frac{(x+2781)}{x}$

Using cross-multiplication: 8x = 5(x + 2781)

Distribute: 8x = 5x + 13,905

Inverse operations: 3x = 13,905 or x = $4,635

Since 'x' represents the amount that Daniel received, than Frank received:

x + 2781 or 4,635 + 2,781 = $7,416

To find the remaining amount for Elliot, make another proportion:

$\frac{Daniel}{Elliot}=\frac{5}{7}=\frac{4635}{y}$

Cross-multiply and divide: 5x = 7(4635) or y = $6,489

Total amount = $6,489 + $4,635 + $7,416 = $18,540

The population, P, of six towns with time t in years are given by the following exponential equations:

Oksanka [162]

Given:

The population, P, of six towns with time t in years are given by the following exponential equations:

(i) $P=1000(1.08)^t$

(ii) $P = 600 (1.12)^2$

(iii) $P =2500 (0.9)^t$

(iv) $P=1200 (1.185)^t$

(v) $P=800 (0.78)^t$

(vi) $P=2000 (0.99)^t$

To find:

The town whose population is decreasing the fastest.

Solution:

The general form of an exponential function is:

$P(t)=ab^t$

Where, a is the initial value, b is the growth or decay factor.

If b>1, then the function is increasing and if 0<b<1, then the function is decreasing.

The values of b for six towns are 1.08, 1.12, 0.9, 1.185, 0.78, 0.99 respectively. The minimum value of b is 0.78, so the population of (v) town $P=800 (0.78)^t$ is decreasing the fastest.

Therefore, the correct option is b.

The length of giselles arm is 27 inches.The length of her lower arm is 17 inches.About what percent of giselles arm is her lower

elena-s [515]

27 divided by 100 is 0.27 so 0.27 is one percent now 17 divided by 0.27 is about 62.963 so 17 is 62.963% of 27 hope this helped.

It is easy! I got you! So if Gavin earned $25 more then Seiji and the total of money they got over the summer is $425, all you have to do is subtract, so 425- 25= 400. Seiji earned s and Gavin earned g.
