Answer:

y = 60°

Step-by-step explanation:

The tangent- chord angle y is half the measure of its intercepted arc , then

y = [tex]\frac{1}{2}[/tex] × 120° = 60°

The value of y is 60 °

Given , the angle is 120°

Now apply the  tangent- chord angle theorem, " a chord meeting at the point of tangency is half the measure of the intercepted "

y = 1/2 × 120°

y = 1/2 × 120° = 60°

Therefore, the value of angle y is 60°.

Answer:

3 3/7 minutes

Step-by-step explanation:

This calculated using the formula:

1/x + 1/y = 1/n

Where

x = Number of minutes it took Ann to walk = 6 minutes

y = Number of minutes it took Alek to walk = 8 minutes

n = Number of minutes it would take An and Alek to reach the starting point at the same time

1/6 + 1/8 = 1/n

Lowest Common Denominator = 24

4 + 3/24 = 1/n

7/24 = 1/n

Cross Multiply

7n = 24

n = 24/7

n = 3 3/7 minutes

It would take them 3 3/7 minutes to reach the starting point at the same time.

Answer:

Mean: 49

Median: 41

Mode: 45

Range: 70

Step-by-step explanation:

To find the mean: add up all the numbers, then divide by how many numbers there are.

To find the median:

Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

To find the mode: The mode of a data set is the number that occurs most frequently in the set.

To find the range: The range is the difference between the smallest and highest numbers in a list or set. To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest.

i) Area = length x width

=250 x 100

= 25000 cm2

ii) it is a square so the sides are equal

Area = 10 x 10

= 100cm2

iii) 25000/100

250 tiles will be needed

Iv) one tile is 4.75 dollars

Total tiles are 250

Cost for tiling

=250 x 4.75

=1187.5

Answer:

the total price of the CD including tax is $11.984

Step-by-step explanation:

The computation of the total price of the CD including tax is shown below:

The Selling price of the CD is $14

CD is 20% off

And, the sales tax rate is 7%

So, the total price of the CD is

= ($14 - $14 × 20%) × (1.07)

= $11.2 × 1.07

= $11.984

Hence, the total price of the CD including tax is $11.984

answer :

A, C, and D

Answer:

0.89

Step-by-step explanation:

The probability of Larry making the next free throw is, 0.89

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one

Now, we can assume that Larry Bird has a 89% chance of making any given free throw.

Since, each free throw is an independent event, the fact that he made 10 free throws in a row does not affect the probability of him making the next free throw.

Therefore, the probability of Larry making the next free throw is also 89%.

Thus, the probability of Larry making the next free throw is, 0.89

Answer: See explanation

Step-by-step explanation:

Since Tim's family toured the Astronaut Hall of Fame from 2:05P.M. To 2:45 P.M, the time taken during the tour will be:

= 2.45 pm - 2.05pm

= 40 minutes.

Since Tim's family toured the Astronaut Hall of Fame for 40 minutes, this shows that they spent more than 30 minutes during the tour.

Answer: 4/5

Step-by-step explanation: We are finding sin C so that means we should divide the opposite side of angle c by the hypotenuse of the triangle. (Soh Cah Toa). The opposite side of angle c is 28 and the hypotenuse is 35. The answer is 28/35 which simplifies into 4/5. hope this helps gg

Answer:

y: 71 degrees

z: 71 degrees

v: 71 degrees

x: 54.5 degrees

w: 54.5 degrees

Step-by-step explanation:

Ok, I might be wrong, please don't hate me!!!!

Since all triangles are 180 degrees, you can find all the measure while knowing only one angle measure.

To find y and z, you need to subtract 180 degrees by 38 degrees:

180 - 38 = 142

Since there are two angles, you need to divide the answer by 2.

142 / 2 = 71 degrees.

Since y and v are directly across from each other, they are the same measure (71 degrees).

With measures x and w, you do the same process of subtracting 180 by the value you know.

180 - 71 = 109

Then divide by 2.

109 / 2 = 54.5 degrees.

Answer:

Answer:

260.0234 cm

Step-by-step explanation:

The formula for area of a circle is π r².

Since the radius is half of the diameter, we must divide the diameter by 2.

18.2/2 = 9.1

Next, we must multiply 9.1 x 9.1.

This gives us 82.81

Now we must multiply 82.81 by pi (3.14).

82.81 x 3.14 = 260.0234

Therefore, the area of the circle is 260.0234.

Answer:

Approximately mMK is 53 degrees

Step-by-step explanation:

Here, we want to find the length of MK

As we can see, we have a right triangle at LNK

so

let us find the angle at L first

9 is adjacent to the angle at L and also, 15 is the hypotenuse of the angle at L

so the trigonometric identity that connects adjacent to the hypotenuse is the cosine

It is the ratio of the adjacent to the hypotenuse

So;

cos L = 9/15

L = arc cos (9/15)

L = 53.13 degree

Approximately, L = 53 degrees

so now, we want to get the arc length MK

We are to use the angle-arc relationship here

Using this; arc length MK is equal to the measure of L at the center which is 53 degrees
