Help please, Ill try to give branliest if it is right :)

Answer:

a) 1/13

b) 0.077

c) 7.69%

Step-by-step explanation:

4 kings in a standard 52 card deck. Just find the fraction of 4/52 and then you will be able to find the percent, decimal and of course, fraction.

Answer:

Here are all 52 cards

A♥ 2♥ 3♥ 4♥ 5♥ 6♥ 7♥ 8♥ 9♥ 10♥ J♥ Q♥ K♥

A♦ 2♦ 3♦ 4♦ 5♦ 6♦ 7♦ 8♦ 9♦ 10♦ J♦ Q♦ K♦

A♠ 2♠ 3♠ 4♠ 5♠ 6♠ 7♠ 8♠ 9♠ 10♠ J♠ Q♠ K♠

A♣ 2♣ 3♣ 4♣ 5♣ 6♣ 7♣ 8♣ 9♣ 10♣ J♣ Q♣ K♣

Here are all the cards that are either a club or a 5:

5♥

5♦

5♠

A♣ 2♣ 3♣ 4♣ 5♣ 6♣ 7♣ 8♣ 9♣ 10♣ J♣ Q♣ K♣

Count them. There are 16.

So the probability is 16 out of 52 or 16/52 which reduces to 4/13.

Step-by-step explanation:

Step 1: figure out the total number of cards you might pull.

Write down all the possible cards and mark the ones that you would pull out (in our case we’ve been asked the probability of a club or a seven so we’re going to mark all the clubs and all the sevens):

hearts: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A

clubs: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A

spades: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A

diamonds: 2, 3, 4, 5, 6, 7, 8, 9, 10, j, q, k, A

This totals 16 cards. *

Step 2: Count the total number of cards in the deck(s). We have one deck, so the total = 52

Step 3: Write the answer as a fraction. Divide step 3 by Step 4:

16 / 52

Answer:

B = 7mm

Step-by-step explanation:

This is probably an enlargement problem.

To solve this:

the blue triangle has all of it's measurements you need. Let's start with that.

6/36 =

We know that one side, the bottom side of the green triangle is 42mm.

6/36 = b/42

We could simplify 6/36 into 1/6

1/6 = b/42

AHA! the denominators are easy! 6 times 7 is equal to 42, so 1 times 7 should equal b!

1/6 = 7/42

Check:

6/36 = b/42

36b = 6*42

36b = 252

   b = 252/36

   b = 7

So yes! B is 7 mm. Pls mark me brainliest, as I never have a single brainliest.

Answer:

351.68cm

Step-by-step explanation:

Using the attached diagram

Radius of the circle = 56cm

Circumference of the circle =2πr

r is the radius of the circle

Circumference of the circle =2(3.14)(56)

Circumference of the circle = 6.28 *56

Circumference of the circle  = 351.68cm

Hence the circumference area of the circle is 351.68cm

Step-by-step explanation:

Answer:

4 ft by 8 ft

Step-by-step explanation:

Answer:

D. 4ft by 10ft

Step-by-step explanation:

Since each square represents 4 feet and the door is 2 blocks plus a bit up it can't be 8 ft since 8ft would only be 2 blocks exactly, this also rules out B since 12 ft would need to be 3 blocks high. this leaves A and D. The third square is only half of a normal square which means its half of 4, 2. You add this to 8 to get 10.

Answer:

The variable x is being divided by 15 in the equation and x=15

Step-by-step explanation:

To solve for x we :

9+x/15=10

x/15=1

x=15

Answer:

I think it would be 2 miles

Step-by-step explanation:

This is because 1/4 of an hour is 15 minutes

so in 15 minutes he swims half a mile

4 x 15 = 60 minutes

so 4 x 1/2 = 2miles

Answer:

13. -4 14. -11 15. [tex]-\frac{11}{3}[/tex]

Step-by-step explanation:

13. (1-3-10)/3

14. (-15+4-22)/3

15. (-7.5+3-6.5)/3

Answer:

13. -4 14. -11 15. -3.6 continued

Step-by-step explanation:

13. 1+-3= -2+-10 -12/3= -4

14. -15+4= -11+-22= -33/3 -11

15. -7.5+3= -4.5+ -6.5= 11/3= -3.6 continued

Answer:

I don't know but I can help you understand it.

Step-by-step explanation:

First find the the answer to the problem and then try to compare all of them to each other and choose the one that makes the most sense.

Answer:

4/5

Step-by-step explanation:

8/15 = 8/15

3/5 = 9/15

2/3 = 10/15

11/15 = 11/15

We see that the pattern is that the terms increase by 1/15 as they move up.

Thus, the next term in the sequence is 12/15, which can be simplified to 4/5.

Answer:

p = 4

Step-by-step explanation:

9p - 3p - 5 = 19

First you subtract like terms which gives you

6p - 5 = 19

Then you move the constant to the right and change its sign which gives you

6p= 19 + 5

Then calculate your answer which gives you

6p=24

Then divide both sides by 6 which gives you

p=4

Answer:

X=11

Step-by-step explanation:

The output is 19.2 which is 19.2=1.2x+6.

Subtract 6 from 19.2 and you get 13.2.

Then divide by 1.2 and you get 11=x :))

Hope this helped:)) Please mark brainliest:))

Answer:

slope = 0  

Step-by-step explanation:

1) Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to solve for the slope. Use the x and y values of the given points, substitute them into the formula, and solve like so:

[tex]m = \frac{(4)-(4)}{(8)-(-9)} \\m = \frac{4-4}{8+9} \\m = \frac{0}{17} \\m = 0[/tex]

Thus, the slope is 0.
