Answer:

i) y = 30°

ii) 30°

Step-by-step explanation:

Total exterior angle = 360

3y° + 4y° + 5y° = 360

12y° = 360

y° = 30°

Interior angle = 180 - exterior angle

Interior angle will be the smallest when the exterior angle is the greatest, which is:

5y = 5(30) = 150°

Smallest interior angle = 180 - 150

= 30°

Answer:

i. 30 degrees

ii. 30 degrees

Step-by-step explanation:

The exterior angles of a triangle always add up to 360 degrees. Using this, you can set up the following equation.

3y+4y+5y=360

y=30 degrees

The smallest interior angle corresponds to the largest exterior angle. 5y=5*30= 150. Subtracting this from 180 you get 30 degrees, or the smallest interior angle. Hope this helps!

What is the slope of a line that is parallel to the line shown? (3,3) (-3,-1)

Sidana [21]

Answer:

2/3

Step-by-step explanation:

Parallel lines have the same slope and will never intersect

slope = (y-y') / (x-x') = (3 - (-1)) / (3 - (-3)) = 4/6 = 2/3

A state lottery involves the random selection of six different numbers between 1 and 30. If you select one six number combinatio

vitfil [10]

Option C

The probability that it will be the winning combination is:

$P = \frac{1}{427518000}$

Solution:

The probability is given as:

$Probability = \frac{\text{number of favorable outcomes}}{\text{total number of outcomes}}$

Given that,

A state lottery involves the random selection of six different numbers between 1 and 30

There are 30 numbers from 1 to 30

The probability that the first digit of lottery number is same as picked can be calculated as:

$P(1) = \frac{1}{30}$

Since, already we picked 1 digit, now total outcomes = 30 - 1 = 29

The probability that the second digit of lottery number is same as picked can be calculated as:

$P(2) = \frac{1}{29}$

Similarly, The probability that the all digit of lottery number is same as picked can be calculated as:

$P = P(1) \times P(2) \times P(3) \times P(4) \times P(5) \times P(6)\\\\P = \frac{1}{30} \times \frac{1}{29} \times \frac{1}{28} \times \frac{1}{27} \times \frac{1}{26} \times \frac{1}{25}\\\\P = \frac{1}{427518000}$

Thus Option C is correct

The surface area of a cell phone screen is 6800 mm2. Use the fact that 10 mm = 1 cm to convert this area to cm2. Round your answ

Dafna1 [17]

Answer:

$68 \: {cm}^{2}$

Step-by-step explanation:

You can use 1 cm = 10 mm very well to help you with this.

The small two at the end of the unit (cm^2) refers, that the shape of an object is two dimensional. If we make 1 cm two dimensional by multiplying it with the original 1 cm, we get a total area of

$1 \: {cm} \times 1 \: {cm} \: = 1 \: {cm}^{2}$
