The diameter of a circle is 40 m. Find the area of the circle in terms of pi

Answers

Answer 1

Answer: 400π

Step-by-step explanation:

The formula for the area of a circle is πr²

First you have to calculate the radius by halving the diameter so radius is 20m.

Then you put in your calculator πx20²

This equals 400π (in terms of pi).

A team won 8 games and lost 5.
What’s the Fraction of the games lost?

Answers

5/13 I believe since you add how many games won and lost and you get 13 and since you want to know how many games lost as a fraction it would be 5/13

Answer:

5/13

Step-by-step explantion:

You already know that they lost 5 games witch is the numerator. Then you add all the games to get the denominator. 8 + 5 = 13

So the answer is 5/13

A participant plans to attend 3 sessions. Here is a list of all possible samples of size 3 sessions from this population of 5 sessions: ABC, ABD, ABE, ACD, ACE, ADE, BCD, BCE, BDE, and CDE. If sessions A, B, and C are selected, what is the sample minimum session cost?

$50
$66.67
$100
$200

Answers

When the list of all possible samples of size 3 sessions from this population of 5 sessions are given. The sample minimum session cost should be considered as the $200.

Calculation of the sample minimum session cost:

Since

Session A: $50

Session B: $50

Session C: $100

Session D: $150

Session E: $200

So here the minimum cost be

= $50 + $50 + $100

= $200

hence, The  sample minimum session cost should be considered as the $200.

What is the value of x in the equation 2x - 3/5 = -1/10

Answers

Answer:

1/4

Step-by-step explanation:

you add 3/5 to the other side and find the lcm making it 6/10--1/10=5/10. Then 5/10 divided by 2 = 2.5/10 which you can simplify to 1/4.

Answer: x=1/4

Step-by-step explanation:

1. Isolate x: if you move -3/5 to the other side, your equation would become

=> 2x=-1/10+3/5

2. Find the common denominator: since you can't add -1/10 with 3/5 without simplifying, you're equation would change to this:

=> 2x=-1/10+6/10

3. Simplify:

=> 2x=5/10  =>  2x=1/2

4. Divide:

=> 2x=1/2  =>  x=1/2*1/2  =>  x=1/4

Which statement about the properties of Function A and Function B are true?
Select each correct statement.
A The Y-intercept of Function A is equal to the Y-intercept of Function B.
B The Y-intercept of Function A is less than the Y-intercept of Function B.
The Y-intercept of Function A is greater than the Y-intercept of Function B.
D The rate of change of Function A is equal to the rate of change of Function B.
E The rate of change of Function A is less than the rate of change of Function B.

Answers

Answer:

B. The Y-intercept of Function A is less than the Y-intercept of Function B

F. The rate of change of Function A is greater than the rate of change of Function B

Step-by-step explanation:

Function A rate of change and y-intercept:

✔️Rate of change using two pairs of values from the given table, (1, 2) and (3, 10):

Rate of change = ∆y/∆x = (10 - 2) / (3 - 1) = 8/2 = 4

Rate of change (m) of Function A = 4

✔️ To find the y-intercept (b) of function A, substitute (x, y) = (1, 2) and m = 4 into y = mx + b (slope-intercept form):

2 = 4(1) + b

2 = 4 + b

2 - 4 = b

-2 = b

b = -2

Y-intercept (b) of function A = -2

Function B rate of change (m) and y-intercept (b):

The function, y = 3x + 4 is given in the slope-intercept form, y = mx + b.

Therefore,

Rate of change/slope (m) = 3

Y-intercept (b) = 4

The following staments about the properties of both functions are therefore true:

B. The Y-intercept of Function A is less than the Y-intercept of Function B

F. The rate of change of Function A is greater than the rate of change of Function B

Answers

Answer:

c = 29

Step-by-step explanation:

Law of sines is given as: [tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]

B = 180 - (57 + 44) = 79°

b = 41

C = 44°

c = ?

Thus:

[tex] \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]

Substitute

[tex] \frac{41}{sin(79)} = \frac{c}{sin(44)} [/tex]

Multiply both sides by sin 44

[tex] \frac{41}{sin(79)}*sin(44) = \frac{c}{sin(44)}*sin(44) [/tex]

[tex] \frac{41*sin(44)}{sin(79)}*sin(44) = c [/tex]

c = 29.0140633 ≈ 29

The answer is B. 63 units

Explanation:

Perimeter is the outside of the shape, so you have to add up all the sides.

13+9+8+5+4+13+5+6=63

Perimeter= 63 units

Answer:

The perimeter is 63 units (B).

Step-by-step explanation:

To find the perimeter, you must add up all the sides.

So...

13 + 9 + 8 + 5 + 4 + 13 + 5 + 6 = 63 units

The answer would then be B -> 63 units

Answer:

Radius.

Step-by-step explanation:

A line joining the center of a circle to a point on the circle is called​ a radius.

This ultimately implies that, it is the straight line from the center of a circle to any point on the edge of the circle. Also, radius is half of a diameter i.e diameter divided by the 2.

Generally, the radius is used for calculating the area and circumference of a circle.

Area of a circle = πr²

Circumference of a circle = 2πr

The S.I units for measuring radius is meters.
