Hello there.

Question: <span>Jamie has a deck of 60 sports cards, of which some are baseball cards and some are football cards. Jamie pulls out a card randomly from the deck, records its type, and replaces it in the deck. Jamie has already recorded six baseball cards and nine football cards. Based on these data, what is, most likely, the number of baseball cards in the deck?
12
15
24
30

Answer: You could use ratio to figure this out.
6:9 = 15
6 baseball for 9 football cards
Divide the total by the amount already known
60/15 = 4
Multiply all values by 4.
6 x 4 = 24.
9 x 4 = 36.

In short, the answer is 24.

Hope This Helps You!
Good Luck Studying ^-^

Mark sells his high-tech equipment for €400 at a loss of 20%. What did it cost him?
Assoli18 [71]

100% - 20% = 80%.

400 is 80% of what number?

Let n = the original price.

400 = 0.80n

400/0.80 = n

€500 = n

Understand?

In the system shown below, what are the coordinates of the solution that lies in quadrant I?
Arisa [49]

Answer:

(4,3)

Step-by-step explanation:

Given

x^2+y^2=25

x-y^2=-5

In order to solve the equations, from equation 2 we get

-y^2= -5-x

y^2=5+x

Putting the value of y^2 in equation 1

x^2+5+x=25

x^2+5-25+x=0

x^2+x-20=0

x^2+5x-4x-20= 0

x(x+5)-4(x+5)=0

(x+5)(x-4)=0

So

x+5=0  x-4=0

x=-5   x=4

Now for x=-5

x^2+y^2=25

(-5)^2+y^2=25

25+y^2=25

y^2=25-25

y^2=0

so Y=0  

And for x = 4

x^2+y^2=25

(4)^2+y^2=25

16+y^2=25

y^2=25-16

y^2=9

y= ±3

So the solution to the system of equations is

(-5,0) , (4,3), (4,-3)

The only solution that belongs to first quadrant is (4,3)
