In circle k(O), AC is a diameter, AB is a chord, and MA is tangent to the circle. Angle MAB is acute. Prove that mMAB=mACB.​

Answers

Let's call C the point on K(O) and segment AO.  I assume you're aware of a 'secant tangent angle theorem', where if you know the measure of arc BC you can solve for angle BAD.  Since CD is a diameter of the circle, the measure of arc CD is 180 degrees - with this you can easily find the measure of all arcs of the circle then apply the theorem

On a camping trip you bring 12 items for 4 dinners. For each dinner you use 3 items. In how many ways can you choose items for the first dinner? for the second? for the third? for the fourth?
​

Answers

Answer:

220 options, 84 options, 20 options, 1 option

Step-by-step explanation:

The first dinner

Combinations of 3 out of 12 items

12C3 = 12!/(12-3)!3! = 12!/9!3! = 12*11*10/2*3 = 220The second dinner

Combinations 3 out of remaining 9 items

9C3 = 9!/(9 - 3)!3! = 9!/6!3! = 9*8*7/2*3 = 84The third dinner

Combinations of 3 out of remaining 6 items

6C3 = 6!/(6 - 3)!3! = 6!/3!3! = 6*5*4/2*3 = 20 The fourth dinner

Combinations of 3 out of 3 remaining items

3C3 = 3!/(3 - 3)!3! = 3!/0!3! = 1

1.3 as a mixed number ​

Answers

Answer: 1 3/10

Step-by-step explanation:

first turn it into a fraction 13/10 then how many times does 13 fit into 10. It fits once with 3 remaining. So you get 1 and 3/10

Answer:

  1 3/10

Step-by-step explanation:

When you read the decimal number, it reads the same as the equivalent mixed number:

  1.3 = "one and three tenths" = 1 3/10

__

Additional comment

This will generally be the case. Some mixed numbers found this way can have their fractions reduced:

  1.2 = "one and two tenths" = 1 2/10 = 1 1/5

Answer:

Step-by-step explanation:

Beth's position over time is constant, which makes the problem a lot easier. You are asked for the rate of position versus time, so begin by doing that. Since the rate is constant, clearly from the table, you can take any two data points and take their ratio. Her rate would be 11 feet every 5 seconds, or equivalently 2.2 feet every second. To graph the data, put position on the y-axis and time on the x-axis. The slope will be 2.2 at every point along her bike ride.

Moving on to the third part. If Amy traveled at a rate of 75 feet every 30 seconds, then she would be traveling 2.5 feet every second. Amy's rate is larger than Beth's rate. Since the rate corresponds to the slope of the postion vs. time graph, Amy's graph will have a steeper incline since the slope is 2.5

Answer:

B. Every 5 minutes 11 ft. traveled

2.2ft.= every 1 minute

C. Steeper. this is because her rate of change is much higher than before

Answers

Answer= 17.2


Explanation: add all of the numbers and divide by the amount of numbers (10 in this situation). 172 divided by 10 = 17.2 average

Answer:

what is mean: mean is the "average" of a set of numbers and it is calculated by adding up the values given and dividing by the total number of values given.

Step-by-step explanation:

formula: addition of all values divided by the number of values given.

total number of values given = 10 ( count each number as one )

so ..

20+15+22+13+14+18+19+11+23+17 = 172

divided by 10

= 17.2 ( decimal)

or 17 whole number 1/5 ( mixed fraction )

or 86/5 ( improper fraction ).

Hope this helps.

John made a triangle with all three sides the same length, 1 \frac{2}{3} ft. What is the perimeter of the triangle?

Answers

Answer:

5 ft

Step-by-step explanation:

If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.

[tex]1\frac{2}{3}[/tex] × 3

[tex]1\frac{2}{3}[/tex] can be rewritten as [tex]\frac{5}{3}[/tex], so:

[tex]\frac{5}{3}[/tex] × [tex]\frac{3}{1}[/tex]

[tex]= \frac{15}{3}[/tex]

The numerator & denominator share a common factor of 3, so:

5 ft is the final answer/perimeter.
