Answer: x= 10

Step-by-step explanation:

Same side exterior angles sum to 180.

Using this axiom we can say that

142+ (3x+8) = 180

Add like terms on the left side

150+ 3x = 180

Subtract 150 from both sides

3x = 30

Divide both sides by 3

X= 10

A. All motion is relative to the frame of reference chosen for measurement.

Step-by-step explanation:

Student 1 riding in the car is going at a certain speed. He sees the bus going a bit faster, so he thinks the bus is going at 20 km/h because to him, since he is also moving, it seems that the bus is only a little faster. Student 2 is on the sidewalk standing. He is not moving. When he sees the bus moving, the bus seems to be going fast because he is not moving. He estimates the speed of the bus to be 50 km/h.

The difference in estimates is due to their frames of reference.

Answer: A. All motion is relative to the frame of reference chosen for measurement.

Answer:  P(Quarter & Penny):  9/100

p(Two pennies): 9/25

Step-by-step explanation:

There are 20 coins in the bag, so you have a 3/20 chance of getting a quarter, 5/20 chances of getting a dime and 12/20 chance of getting a penny on each draw if the coins are always replaced.

Im this situation, you can simplify the fractions, the

Multiply the chance of each independent event times the chance of the next independent event.

3/20 × 3/5 = 9/100 for the quarter and the penny

3/5 × 3/5 = 9/25  for the two pennies

Write an exponential function to describe the given sequence of numbers, assuming that the first number in the sequence corresponds to x = 0.
5.30, 180, 1080, 6480...

Answers

Answer:

[tex]y = 5(6) {}^{x} [/tex]

Step-by-step explanation:

A exponential function is represented by

[tex]y = ab {}^{x} [/tex]

where a is the vertical stretch and b is the base and x is the nth

power of x

Since the first number corresponds with zero, that means our y intercept is the first number.

This means when x=0 , y=5 so let find the value of 5.

[tex]5 = ab {}^{0} [/tex]

b to the 0th power equal 1 so

[tex]5 = a \times 1[/tex]

[tex]a = 5[/tex]

Our equation is for now

[tex]y = 5b {}^{x} [/tex]

Now let plug in 1,30

[tex]30 = 5b {}^{1} [/tex]

Divide 5 by both sides

[tex]6 = b {}^{1} [/tex]

Anything to the 1st power is itself so b equal 6.

So our equation is

[tex]y = 5(6) {}^{x} [/tex]

Express the number of months in the year that are only 4 letters as a fraction in the simplest form, decimal rounded to the nearest thousandth and whole percent.

Answers

Answer:

There are only 2 months out of the 12 that have 4 letters in their name so it would be represented as 2/12, the numerator representing those 2 months and the numerator representing the 12 months in 1 year. 2/12 in its simplest form would be 1/6 because if you use the big one to simplify 2/12 and divided it by 2/2 you get 1/6. 1/6 as a decimal is 0.16 wich is 16% as a percent.

To do it, let:

x: number of grapes that Reza ate yesterday

(x / 20) = (100/400).
