Question is attached!​
saul85 [17]

Answer:

$3,000 was invested in the account that gained 13%

$17,500 was invested in the account that lost 10%

Step-by-step explanation:

Let the amount in both accounts be x and y

x for the first and y for the second

Adding both is 20,500

x + y = 20,500 •••••(i)

First account earned 13% profit

= 13/100 * x = 0.13x

Second account, a loss of 10%

= -10/100 * y = -0.1y

Total loss of -1,360

This is;

-0.1y + 0.13x = -1,360 •••••••(ii)

From i, x = 20,500-y

Insert this into ii

-0.1y + 0.13(20,500-y) = -1,360

-0.1y + 2665 -0.13y = -1360

-0.23y = -1360-2665

-0.23y = -4025

y = -4025/-0.23

y = 17,500

To get x, we have

x = 20,500 -y

x = 20,500- 17,500

x = 3,000

In a 24 km race, during which each runner maintains a constant speed throughout, Alice crosses the finish line while Becky is st
mr_godi [17]

Answer:6km

Step-by-step explanation:

Given

when Alice finishes the race Becky is 8km From finishing line

and caitlin 12 km from finishing line.

Suppose t is the time require by Alice to finish the race

andV_a,V_b,V_c be the velocity of alice ,becky and caitlin

thus t=\frac{24}{V_a}=\frac{24-8}{V_b}=\frac{24-12}{V_c}

thus \frac{V_b}{V_c}=\frac{4}{3}

say t' is time required by beckey  to complete 8 km thus

V_b\times t'=8

therefore for Caitlin

V_c\times t'=\frac{8}{V_b}\times V_c=6

Thus caitlin will cover a distance of 6 km in t' time and 6 km away from finishing.
