Naddika [18.5K]

Answer:

1 / 13

Step-by-step explanation:

The total number of cards in a deck = 52

The total number of aces in a deck = 4

Since selection is drawn with replacement, then probability of drawing a certiaj number of card from the deck will be the same each time a selection is made :

Probability = required outcome / Total possible outcomes

The required outcome = number of aces = 4

Total possible outcomes = total number of cards = 52

P(drawing an ace) = 4 / 52 = 1 /13

Help me with any of these please
kumpel [21]
K, so here we go:
1. 3/4 + 3/4. When adding fractions, you only add the numerator or whole numbers (doesn't have a whole number, but the numerator's are the top numbers) NOT the denominator (bottom number) Add 3+3, and this gives you 6. Keep the 4 the same, and you get 6/4. The answer is 6/4, but you can make this a proper fraction, and say it's 1 and 2/4 (one is the whole number, it's like the 4 in number 3)

2. 2- 1 and 1/8. This is just subtraction, subtract the whole numbers first. 2-1=1. now, assume the 2 is 2 and 0/8, and you just took away 1. Now, it's 1 and 0/8. Now, take away another 1/8 and you get 7/8

3. Just division. The Answer is 3/2, or 1 and 1/2

4. Simple division again. Divide 15 by 3. You get 5. This is 1/3 of 15, because 5*3=15.

5. An 8 sided polygon is known as an octagon. 

6. A=B*H (Area= base times height.)

7. A quarter is 4. It takes 4 quarter pounds to make a pound (think like money. a quarter is 25 cents. it takes 4 quarters to make a dollar. If you want 60 dollars, how many quarters would you need?) Well, take 60*4, and you get 240. You can make 240 quarter pounders from 60 pounds of meat.
___________________________________________________________
 TO CLARIFY:
1= 6/4 OR 1 and 2/4
2= 7/8
3=3/2 OR 1 and 1/2
4=5
5=Octagon. 
6: A=B*H
7. 240 quarter pounders

A rectangular pool 6 meters by 4 meters is surrounded by a walkway of width x meters. At what value of x will the area of the wa
steposvetlana [31]

Answer:

x=1 meter

Step-by-step explanation:

step 1

Find the area of the rectangular pool

A=LW

we have

L=6\ m\\W=4\ m

substitute

A=6(4)=24\ m^2

step 2

Find the area of rectangular pool including the area of the walkway

Let

x ----> the width of the walkway

we have

L=(6+2x)\ m\\W=(4+2x)\ m

substitute

A=(6+2x)(4+2x)

step 3

Find the area of the walkway

To find out the area of the walkway subtract the area of the pool from the area of rectangular pool including the area of the walkway

so

A=(6+2x)(4+2x)-24

step 4

Find the value of x if the area of the walkway equal the area of the pool

so

(6+2x)(4+2x)-24=24

Solve the quadratic equation by graphing

The solution is x=1 meter

see the attached figure
