Answers

Answer:

Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points.

solve for p 9p - 3p 05 = 19

Answers

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

I need help....Does anybody know the answer?

Answers

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.

2.) Kyle swims a 1/2 mile every 1/4 hour. How far will he swim in one hour?

Answers

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

Answers

Answer:

d. 15 m

Step-by-step explanation:

hypotenuse (h) = 25 m

base (b) = 20 m

perpendicular (p) = ?

By using Pythagoras theorem we get

p = √h² - b²

= √ 25² - 20²

= √ 225

= √ 15²

= 15 m

Solve the equation for the red variable

Answers

i think c = p+ r because you firstly have to rearrange the equation so that you isolate the -c. which means you get -c = p-r because you have to change the sign of the r when you switch it. so -c = p-r, but to find c that isn’t minus you need to change the sign on both sides. therefore, the answer should be c = p+r.

If you randomly select a card from a well-shuffled standard deck of 52 cards, determine the probability that the card you
select is a King
a) Write your answer as a reduced fraction,
b) Write your answer as a decimal, rounded to the nearest thousandth.
c) Write your answer as a percent. Round to the nearest tenth of a percent as needed.

Answers

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

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.

Find the Circumference area of the circle. Use 3.14 for pi. Round tithe nearest hundredth if necessary

Answers

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
