Answer:

Step-by-step explanation:

Even without a picture, it is fairly easy to know which ones is the second largest angles.

1) Angle measurements are given: In this case, if the angle measurement is given, then you can directly compare. The second largest angle is your answer.

2) Sides are given (usually in the form of triangles). The angle that has the largest measurement is directly opposite of the hypotenuse, with the second one being directly opposite of the second to largest side.

How many positive integers less than 100 have at least one digit that is a 9? (Let T be the set of positive integers less than 1

Ymorist [56]

Answer:

Step-by-step explanation:

Let T be the set of positive integers less than 100 with a 9 in the ten's place.

T = {90, 91, 92, 93, 94, 95, 96, 97, 98, 99}

n(T) = 10

Let O be the set of positive integers less than 100 with a 9 in the one's place.

O = {9, 19, 29, 39, 49, 59, 69, 79, 89, 99}

n(O) = 10

The common element is 99.

$T\cap O={99}$

$n(T\cap O)=1$

The union of both sets is

$n(T\cup O)=n(T)+n(O)+n(T\cap O)$

$n(T\cup O)=10+10-1$

$n(T\cup O)=19$

Therefore, 19 positive integers are less than 100 those have at least one 9.

A missing piece of a board game, a circular disk, had an area of 100,608.7, the replacement disks are listed using circumference

STALIN [3.7K]

Answer:

1,124.12 mm

Step-by-step explanation:

<u><em>Steps to answering this question : </em></u>

First determine the radius of the circle from the area of the circle

Use the radius determined above to calculate the circumference

Area of a circle = nr²

where r = radius

n = pi = 3.14

100,608.7mm = nr²

to determine the radius, divide both sides of the equation by 3.14

32,040.98726mm = r²

Find the square root of 32,040.98726mm

√32,040.98726mm

r = 179mm

Circumference of a circle = 2nr

2 x 179 x 3.14 = 1,124.12 mm
