ANSWER

B. 310°

EXPLANATION

The sum of angles in a circle is 360°

From the diagram, the measure of arc SY is 50°

The measure of arc STY plus the measure of arc SY is 360°

To find the measure of arc STY, we subtract 50° from 360° to get:

Measure of arc STY

$= 360 \degree - 50 \degree$

This simplifies to

$310 \degree$ The correct answer is B 310°

Answer:

The correct answer is option B. 310°

Step-by-step explanation:

From the figure we can see that, a circle with center o.

And an arc SY with central angle 50°

<u>To find the measure of arc STY</u>

From the figure we can write,

arc SY + arc STY = 360

measure of arc STY = 360 - measure of arc SY

= 360 - 50 - 310°

Therefore the correct answer is option B. 310°

Answer:

-31

Step-by-step explanation:

(2×x) - (2×5) = (3×x) + (3×7)

2x-10 = 3x+21

2x-3x = 21+10

-x = 31

therefore, x = -31

yan [13]

Answer:

There are 2,598,960 ways to receive 5 cards from a deck of 52.

Step-by-step explanation:

The order in which the cards are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

a. How many ways are there to receive 5 cards from a deck of 52?

$C_{52,5} = \frac{52!}{5!(47)!} = 2598960$

There are 2,598,960 ways to receive 5 cards from a deck of 52.

A real estate company wants to build a parking lot along the side of one of its buildings using 800 feet of fence. If the side a

Elden [556K]

Answer:

80,00 $ft^{2}$

Step-by-step explanation:

According to my research, the formula for the Area of a rectangle is the following,

$A = L*W$

Where

A is the Area
L is the length
W is the width

Since the building wall is acting as one side length of the rectangle. We are left with 1 length and 2 width sides. To maximize the Area of the parking lot we will need to equally divide the 800 ft of fencing between the <u>Length and Width.</u>

800 / 2 = 400ft

So We have 400 ft for the length and 400 ft for the width. Since the width has 2 sides we need to divide 60 by 2.

400/2 = 200 ft

Now we can calculate the maximum Area using the values above.

$A = 400ft*200ft$

$A = 80,000ft^{2}$

So the Maximum area we are able to create with 800 ft of fencing is 80,00 $ft^{2}$
