Answer:

$60 and $150

Step-by-step explanation:

Initially

Karen : Peter = 2 : 5

After Peter receiving $75 the ratio is

4 : 15

We can suppose that initally the amount of monye Karen has is 2x and Peter is 5x.

The new ratio is

2x :  (5x +75)  = 4 :15

2x (15)= 4 (5x +75)

30 x = 20 x + 300

10 x = 300

x = 30

So at first Karen has 2x =60 dollars while Peter has 5x = 5(3) = 150 dollars.

Estimate the square root to the nearest integer.
nexus9112 [7]
Answer:
3
Explanation:
3^2 is equal to 9, and 4^2 is equal to 16, so sqrt(10) must be in between 9 and 16. Since 10 is closer to 9 than to 16, sqrt(10) is closer to 3 than 4, which means that to the nearest integer sqrt(10)=3
