If you randomly select a card from a well-shuffled standard deck of 52 cards, what is the probability that the card you select is not a 4? (Your answer must be in the form of a reduced fraction.)

Answer:

Step-by-step explanation:

Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0

f(m)=20-0.25m

0 =20-0.25m

-20 = -0.25m

m = -20/-0.25

m = 80

Hence Trudy will have talked for 80minutes if she has no money left

Answer: 1/2 which equals 50%

Step-by-step explanation:

Answer:

0.5 because there are 4 numbers and 2 of them are even so it would be 1/2

Answer:

D

Step-by-step explanation:

because 5x4= 20 and -3×2=-6 so you need it to equal -6 and C20÷C26 you subtract so it gives you -6

I think this is right but I maybe be wrong

Answer:

y = 3/4x - 1/4

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

Because there are two negatives of the same number, we can instantly know that this would be 0.

Answer: 0

on this one it can’t be undefined so put 0 and you will get it correct

Answer:

He took 5 swimming classes.

Step-by-step explanation:

The problem states that the student paid a total of $56.25 for the classes and also the one-time registration fee. To find the number of classes, we should first subtract the one-time registration fee from the total.

$56.25 - $12.50 = $43.75

Now that we know he spent a total of $43.75 on the classes without the registration fee, we can divide that number by the cost of one class ($8.75) to calculate the total number of classes he took.

43.75 / 8.75 = 5

Answer: x = 160

Step-by-step explanation:

540 = 100+(x-25)+(x-15)+(1/2)x+(1/2)x

540= 100-40+3x = 60+3x

480 = 3x

x = 160

Answer:

0.5x + 0.5x + (x-25) + (x-15) + 100 = 540

x + x - 25 + x - 15 + 100 = 540

3x + 60 = 540

3x = 540 - 60

3x = 480

x = 480/3

x = 160

Complete question :

You have 20 quarters. You find 40% more quarters in your room. Then you go shopping and spend 50% of the total number of quarters.

A. Write an expression that represents the total number of quarters you take with you when you go shopping.

B. How much money do you have left?

Answer:

[20 + (0.4*20)] = 28 quarters

$3.5

Step-by-step explanation:

Given that:

Initial number of quarters = 20

Quarters in room = 40%

Hence, Numbe of quarters in room = 0.4 * 20 = 8

Total number of quarters taken for shopping :

(Initial amount + Numbe of quarters in room)

(20 + 8) = 28 quarters

50% of quarters was spent on shopping :

0.5 * 28 = 14 quarters

Total left :

28 - 14 = 14

Quarters left in dollars :

1 quarter = 25 cent = 0.25 dollars

14 * $0.25 = $3.5

Answer:

Step-by-step explanation:

1) Let the number be y

45%of y=63

45y/100=63

Y=6300/45

Y=140

So 80%of a number =80y/100

=80×140/100

=112.

Let the number be y

35%of y=49

35y/100=49

Y=4900/35

Y=140

So 80%of a number =80y/100

=80×140/100

=112.

Givens

r = 1

V = ?

pi = 3.14

Formula

V = 4/3 * pi * r^3

Solution

V = 4/3 * 3.14 * 1^3

V = 4.1867 m^3

Given :

Initial weight of sumo wrestler, I = 90 kg.

Final weight of sumo wrestler, F = 138 kg.

Time taken, T = 8 months.

To Find :

Weight gain per month.

Solution :

Weight gain per month = ( Final weight - Initial weight ) ÷ Total number of month

[tex]W = \dfrac{138-90 }{8}\ kg/month\\\\W = 6 \ kg/month[/tex]

Therefore, weight gain per month is 6 kg/month.

Hence, this is the required solution.

Answer:

because 8/4=2

Step-by-step explanation:

4/4=1

8/4=2

it's because the numerator is bigger if it were 6/4 it would be a mixed number but the eight goes in to 4 directly 2 time so therefore it's 2.

Answer:

B

Step-by-step explanation:

35% of this price is :

35/100 × x = 0.35x

The price reduces by 0.35x.

This equals to 115.65

Now :

0.35x = 115.65

100/35 × 115.65 = 330.43
