PLEASE HELP!!!!!
Let event A= The student plays Basketball
Let event B= The student plays soccer
What is P(A or B)

Answer:

26/32=13/16

Step-by-step explanation:

Note that the formula for the circumference of a circle is πd, while the formula for the area of a circle is πr².

π≈3.14

A. C=πd

Simply plug in the numbers into the formula.

Diameter=Radius*2

17*2=34

C=34(π)

B. (π)(5²)

Plug in the numbers into the formula. Remember that half of the diameter is the radius.

C.  (π)(4.5)

There are two possible formulas that could be used to calculate the circumference of a circle: πd and 2πr.

The expression above is simply multiplying the circle's radius times pi. Therefore, it is not a method that could be used to find the circumference of a circle.

D. (π)(6.5²)

Remember that the formula for calculating the area of a circle is πr².

Half of the diameter is 6.5 (13.5/2=6.5). 6.5 cm. is the radius. Now just plug the numbers into the formula.

(π)(6.5²)

Therefore, the last answer choice is the correct answer.

Point B is tangent to the circle so the angle ABC would be 90 degrees.

Answer:

40

Step-by-step explanation:

The two angles form a right angle

A right angle has a measure of 90 degrees meaning that the sum of the two angles is 90

a + 50 = 90

90 - 50 = 40

Thus, a = 40

missing angle is (40⁰) :)

Answer:

160 cm^2

Step-by-step explanation:

All you do is separate the boxes, then you l x w to find the answer then add it up when you finish.

A - 2 x 10 = 20

B - 5 x 2 = 10

C - 5 x 10 = 50

D - 5 x 2 = 10

E - 2 x 10 = 20

F - 5 x 10 = 50

Add these numbers up (all of them!) to get your answer.

What you would get is 160.

Answer:

-11

Step-by-step explanation:

Simply plug in a=-3 and b=2 into the equation provided. Remember the signs (+/-) and be careful with your calculations.

Answer: 60

8x15 / 2

Step-by-step explanation:

Answer:

40 units

Step-by-step explanation:

Using Pythagoras Theorem to find the hypotenuse:

[tex] \sqrt{ {15}^{2} + {8}^{2} } [/tex]

[tex] = \sqrt{289} [/tex]

= 17 units

The perimeter

= 15+8+17

= 40 units

Answer:

John and Shawn spent the same number of hours after [tex]4[/tex] weeks.

Step-by-step explanation:

Number of hours already completed by John to his volunteer project [tex]=40[/tex] hours

Number of hours spent by John each week to his volunteer project [tex]=5[/tex] hours

Number of hours spent by Shawn each week to his volunteer project [tex]=15[/tex] hours

Suppose John and Shawn spent the same number of hours after [tex]x[/tex] weeks.

Therefore,

[tex]40+5x=15x[/tex]

[tex]40=15x-5x\\40=10x[/tex]

[tex]x=4[/tex] weeks.

So,

John and Shawn spent the same number of hours after [tex]4[/tex] weeks.

Answer:

the first step is to divide two by three x

Answer:

x = 12

Step-by-step explanation:

Eliminating the fractional coefficient would be a great start:

8 = (2/3)x becomes 24 = 2x after multiplication of both sides by 3.

Then x = 12

Answer:

[tex]\\\\\frac{P^3 \ + \ 1}{P^3} = 0[/tex]

Step-by-step explanation:

Given;

[tex]\frac{P-1 }{P} = 2\\\\From \ the \ equation \ above \ we \ determine \ the \ value \ of \ p \ as \ follows;\\\\P-1 = 2P\\\\P-2P = 1\\\\-P = 1\\\\P = -1[/tex]

[tex]Now\ solving \ the \ given \ question;\\\\\frac{P^3 \ + \ 1}{P^3} \\\\Substitute \ the \ value \ of \ "P" \ into \ the \ equation;\\\\\frac{P^3 \ + \ 1}{P^3} = \frac{(-1)^3 \ + \ 1}{(-1)^3} = \frac{-1 \ + \ 1}{-1} = \frac{0}{-1} = 0[/tex]

Answer:

Hello again! x = 85

Step-by-step explanation:

Because triangles are 180 degrees and

68 + 27 = 95 and 180 - 95 = 85 so our missing angle is 85 hope this helps!

Answer:

a = 93°, b = 120°, c = 150°

Step-by-step explanation:

b + 36 = 78 × 2 => b + 36 = 156 => b = 120°

87 × 2 - b = the minor arc between a and 78

=> 174 - 120 = 54

54 + b + 36 + c = 360

=> 54 + 120 + 36 + c = 360

=> c = 150°

(c + 36) ÷ 2 = a

=> (150 + 36) ÷ 2 = a

=> a = 93°

Answer:

C. Zero

Step-by-step explanation:

The solution of the system of equations would be the point where they intersect, but since these lines are parallel, they will never intersect, so therefore there are zero solutions.

Answer:

Slope = -⁵/3

Step-by-step explanation:

See the attachment below. In the attachment, the green line represents the the rise while the red line represents the run of the line.

The slope = rise/run

Rise = 5

Run = 3

Slope = -(5/3)

Slope = -⁵/3 (the slope would be negative because the line slants downwards from your left to the right)

Answer:

6/7

Step-by-step explanation:

The constant rate of change is also know as the slope of the expression

Given

24x-28y=14

Write in standard form y = mx+c

m is the slope

24x-28y=14

-28y = -24x + 14

y = -24x/-28 + 14/-28

y = 6/7 x - 1/2

Compare

mx = 6/7 x

m = 6/7

Hence the  constant rate of change is 6/7

Answer:

C. 12

Step-by-step explanation:

Find the percentage of him drawing a blue marble.

4/10 = 0.4

He has a 40% chance of picking blue.

Find 40% of 30.

12

He would draw a blue marble around 12 times.

Answer:

C

Explanation:

So in the bag, there are 10 marbles, and 4 of them are blue, so if he drew from the bag 10 times, we can assume the fraction:

4/10

Next, we see that the denominator, or the number times Cade is drawing from the bag is 30, which makes us multiply most sides of the fraction by 3:

12/30

So I would say 12/30, but again, he wouldn't draw a blue exactly 4 times, and it may be more or less, so either 8/12....

Hope this helps!

Answer:

212 meters

Step-by-step explanation:

The diagonal of a square is the square root of 2 times the length of the square. This can be rewritten as the square root of (2*area)

2 * 22500 = 45000

The square root of 45000 is about 212.13, which would round down to 212 meters.

Answer:

176 cm

Step-by-step explanation:

Area of a triangle = h b/2

8 * 11 ÷ 2 = 44 cm

Area of a rectangle = l * w

12 * 11 = 132 cm

Add both areas together

44 + 132 = 176 cm

Answer:  B: 0.81 miles

Step-by-step explanation:

The find the total distance, you must look for firs the missing side. To get use the formula that is derived from the Pythagorean theorem which states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

The formula for this is: a^2 + b^2 = c^2

So let the first side or a be .19

and the second side be .28

and now we are looking for c which is the missing side

.19^2 + .28^2 = c^20.0361 + 0.784 = .1145

get the square root of .1145

√.1145 = it is approximately 0.34

get the total distance by adding three sides

= .34 + .19 + .28

= 0.81
