The diameter of a circle is 20 ft. Find its area in terms of
π

Answer:

8:6 , 12:9 , 16:12

Step-by-step explanation:

To find equivalent ratios is like finding equivalent fractions :

We simply multiply both numbers of the ratio by the same number.

You can also do the reverse to simplify a ratio.

4:3 × 2 = (4×2):(3×2) = 8:6

4:3 × 3 = (4×3):(3×3) = 12:9

4:3 × 4 = (4×4):(3×4) = 16:12

Therefore 3 ratios that are equivalent to 4:3 are :

8:6 , 12:9 , 16:12

Answer:

8:6 and 12:9

Step-by-step explanation:

Answer:

A, B, and E.

Step-by-step explanation:

We know that one vertex is at (5, 4), and each side of our square is 3 units long.

Then the distance between the known vertex and another vertex is 3 units (if those vertexes are connected by a side of the square) or (√2)*3  units (if those vertexes are connected by the diagonal of the square).

Also remember that the distance between two points (a, b) and (b, c) is:

distance = √(  (a - c)^2 + (b - d)^2)

So we need to find the distance between our point and all the ones given in the options:

A) the distance between (5, 4) and (5, 1) is:

distance = √( (5 - 5)^2 + (4 - 1)^2) = 3

Then point (5, 1) can be a vertex.

B) The distance between (5, 4) and (5, 7) is:

distance = √( (5 - 5)^2 + (4 - 7)^2) = 3

Then (5, 7) can be a vertex.

C)  The distance between (5, 4) and (7, 8) is:

distance = √( (5 - 7)^2 + (4 - 8)^2) = √( 2^2 + 4^2) = √20

Point (7, 8) can not be a vertex.

D)  The distance between (5, 4) and (2, 6) is:

distance = √( (5 - 2)^2 + (4 - 6)^2) = √( 3^2 + 2^2) = √13

Point (2, 6) can not be a vertex.

E) The distance between (5, 4) and (2, 1) is:

distance = √( (5 - 2)^2 + (4 - 1)^2) = √( 3^2 + 3^2) = √18 = √(2*9) = √2*√9 = √2*3

Then point (2, 1) can be a vertex.

Answer:

1h 34min

Step-by-step explanation:

7: 09 AM to 8: 42 AM is 1h 34min because if you add an hour to 7: 09 AM it will be 8: 09 AM then add 34 to 9 and it will be 42.

Answer:

69.08

Step-by-step explanation:

Answer:

60

Step-by-step explanation:

Angle AFC is supplementary to angle CFE. Supplementary angles always equal 180 degrees. (180-120=60)

Answer:

1. 60

2. 120

3.30

Step-by-step explanation:

(Yes I know they aren't labeled one and two but I'll go in order from the questions)

1. It is 60, because it is an equilateral triangle so all angles are equal. 180/3=60.

2. There are two ways you can solve this problem. The first is using the vertical angle theorem. That makes it 120. Or, you can add all the angles you have already and remove it from 360.

360-120-60-60=120.

(you can tell it is not 60 because it is larger than a right angle in the picture)

3.x=30.The right angle is 90, and there is a 60 degree angle, so 90-60=30

Answer:

B. 1 out 6

Step-by-step explanation:

There is only one number on a six sided die that has a number less than 2, so it would be 1/6.

Answer:

A triangle is 180 degrees and you have a 30 and 50 angle so the third angle should equal 100. so the answer should be 45 and here's why

Step-by-step explanation:

Subtract 10 from both sides

2x+10=100

2x+10-10=100-10

Simplify

Subtract the numbers

2x=90

Divide both sides by the same factor

2x=90

2x/2 = 90/2

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

x=45

Solution

45

Answer:

first one and  thrid one

Step-by-step explanation:

Answer:

a: 89/100

b: 19/100

c: 28/100

Step-by-step explanation:

for a, take every number greater than 10. there are 100 chips, so 89/100 chips are greater than 10. do this for each of the other questions.

The order for the probabilities of the events by placing the event with the greatest probability on top is

1. The label is a number between 30 and 60

2. The label is a number less than 20

3. The label is a number greater than 10

Below are the correct order of the probabilities from greatest to least:

1. The label is a number between 30 and 60

2. The label is a number less than 20

3. The label is a number greater than 10

The reason for this order is that there are 31 chips with labels between 30 and 60, 19 chips with labels less than 20, and 90 chips with labels greater than 10.

Therefore, the correct answer is as given above.

Answer:

The center of the circle is the point in the center.

The radius of the circle is the line segment from the center of the circle to the circumference of the circle.

The diameter is the widest part of the circle. It is a straight line that touches two points on the circumference and passes through the center point.

Question 1

Center = R

Radius = RS and RP and RQ

Diameter = PRQ

Question 2

Center = C

Radius = CD and CA and CB

Diameter = ACB

Question 3

Center = L

Radius = LK and LJ

Diameter = JLK

Answer:

the answer is february

Step-by-step explanation:

When you go into this problem, you want to figure out your marble ammount to 50 so in this case we will say C for color and 50 for the total ammount of marbles.

We know 15 are pink, 8 are black, 2 are green, 18 are clear, and 7 are striped

15P/50

8B/50

2G/50

18C/50

7S/50 for a total of 50 marbles

Now we use the chart to decide our awnsers  

A. We know our propability of drawing a green and clear is 20/50 which if we simplify is a 2/5 ratio. If We put this in perspective 2/5 is rare and is unlikley to even.

B. We know a striped marble is 18/50 or 1.8/5 ratio which is mainly unlikely

C. We have 23/50 marbles that are black and pink, our propability is about 2.3/5 and gives us an even chance to get one of these

D. We know we have 33/50 marbles that are pink and clear and gives us a 3.3/5 chance of getting one of  these and gives us an even to likely chance of getting one of these.

E. If we have a total of 17 marbles in these 3 colors, we have a 1.7/5 chance of getting one of these and is probably impossible to unlikey.

Answer:

1/3

Step-by-step explanation:

Figure A is

-the initial one and

-is bigger

so the scale factor is less then 1 and the figure A was shrunk to figure B

If we compare the sides of the triangles we see that the green triangle was shrunk by a k= 1/3 factor into the blue triangle.

Blue triangle is 3 times smaller than green triangle.
