Take a ruler and measure the longest side and the shortest side.
Multiply the long side by 2, because there are two of them.
Multiply the short side by 2, for the same reason.
Add the 2 answers that you got together for the perimeter.

Dont forget, if it's under 1/4 inch round down. If it is over 1/4 inch round up to the 1/2 inch.

What ever u measured you add 4 times.

For example -

Each side was 1 1/2 inch

1 1/2 + 1 1/2 + 1 1/2 + 1 1/2= 6

Find the value of x. Everything is in the photo.

Elan Coil [88]

Answer:

Step-by-step explanation:

Note that since VX and XZ are both line segments, <VWX and <XYZ both equal 180 (also known as a straight angle). Also, note that the sum of the angles in a triangle are 180 degrees. Now, let’s start.

Finding angles of the triangle:

<WYX = <XYZ - <WYZ = 180 - 4x

<XWY = <XWV - <VWY = 180 - 6x

Using the sum of angles in a triangle and substituting these values in:

180 = <X + <WYX + <XWY = 90 + (180 - 4x) + (180-6x) = 450 - 10x

270 = 10x

We are done! I hope this helps! :)

3. Suppose that you draw two cards from a standard 52 card deck. You replace the first card and shuffle thoroughly before you dr

Kruka [31]

Answer:

$\text{a)} \frac{1}{17} \text{b)} \frac{1}{221}\text{c)}\frac{12}{13}\text{d)}\frac{188}{221}$

Step-by-step explanation:

GIVEN: You draw two cards from a standard $52$ card deck. You replace the first card and shuffle thoroughly before you draw the second.

TO FIND: a) What is the probability that the first card is $7$ b) What is the probability that both cards are

SOLUTION:

Let $\text{A}$ and $\text{B}$ be two events such that

$\text{A}$ $=\text{first card drawn is 7}$

$\text{B}$ $=\text{Second card is 7}$

$\text{probability that first card is 7 =P(A)}$

<h3> $\text{P(A)}=\frac{\text{total 7 numbered cards}}{\text{total cards in deck}}$ </h3><h3> $\text{P(A)}=$ $\frac{4}{52}=\frac{1}{13}$ </h3>

$\text{probability that first card is 7 =P(A)}$

$\text{probability that both cards are 7}=$ $\text{first card is 7}\times\text{second card is 7}$

$\text{probability that both cards are 7}=$ $\text{P(A).P(B)}$

$\text{P(B)}=\frac{\text{total number of 7 numbered cards left}}{\text{total number of cards in deck left}}$

$\text{P(B)}=\frac{3}{51}=\frac{1}{17}$

$\text{probability that both cards are 7}=$ $\frac{1}{13}\times\frac{1}{17}$

$\text{probability that both cards are 7}=$ $\frac{1}{221}$

$\text{probability that first card is not 7}=1-\text{probability that first card is 7}$

$\text{probability that first card is not 7}=$ $1-\text{P(A)}$

$\text{probability that first card is not 7}=$ $1-\frac{1}{13}$

$\text{probability that first card is not 7}=$ $\frac{12}{13}$

$\text{probability that both cards are not 7}=$ $(\text{first card is not 7}).(\text{second card is not 7})$

$\text{probability that both cards are not 7}=$ $\text{[1-P(A)].[1-P(B)]}$

$\text{P(B)}=\frac{\text{total 7 numbered cards}}{\text{total cards left in deck}}$

$\text{probability that both cards are not 7}=$ $(1-\frac{1}{13})\times(1-\frac{4}{51})$

$\text{probability that both cards are not 7}=$ $\frac{12}{13}\times\frac{47}{51}$

Please help I need the 3 equations to solve for each type of point.

Law Incorporation [45]

Answer:

f = 0

x > 2y

x ≤ 8

S ≥ 18

Step-by-step explanation:

Let 'f' represent the number of free throws.

Let 'x' represent the number of 2 - point baskets.

Let 'y' represent the number of 3 - point baskets.

Let S represent the Season high.

1) Ryan says he did not shoot any free throws.

⇒ f = 0

2) 2 - point baskets more than twice the number of 3 - point baskets.

⇒ x > 2y

3) Number of two points is less than or equal to 8.

⇒ x ≤ 8.

4) Last Season high, he had scored 18 points. Note that the problem says, Ryan equaled or bettered than last season high. That means he should got at least 18 points this season. So, the equation would be:

S ≥ 18

Select the property NOT used in the following

Fudgin [204]

(2 + a) = (a + 2) it's commutative property

(a + 2) - 7 = a + (2 - 7) it's associative property

2 - 7 = -5 it's subtraction

Answer: distributive property { a(b + c) = ab + ac }
