Step-by-step explanation:

every day is a new day and a new opportunity to change the world no matter how BIG or how small.  even if you make mistakes. always remember this though. whatever you put into the world, whether it be good or bad, it will always come back three times.

meaning that when you do something good something three times as good will happen to you. The same is so for bad except it would be 3 times as bad as will happen to you.   I hope your day is great and may you do many great things.

During its grand Opening weekend, a restaurant gave every 8 customers a free appetizer, every twelfth customers a free becverage, and every fifteen customer a free fish of yogurt. which customer was the first to recive all three ítems?

Answers

Answer:

120th customer will be the first one get all the three items.

Step-by-step explanation:

Given that:

Every 8th customer gets a free appetizer.

Every 12th customer gets a free beverage.

Every 15th customer gets a free fish of yogurt.

To find:

The first customer to receive all the three items.

Solution:

Here, we need to find nothing but the Least Common Multiple of the given three numbers 8, 12 and 15 to find the first person who will get all three free items.

Let us use factors of each number:

[tex]8 = 2\times 2\times 2\\12 = 2\times 2\times 3\\15 = 3\times 5[/tex]

The LCM will be:

[tex]2\times 2\times 2 \times 3 \times 5 = \bold{120}[/tex]

Therefore, the answer is:

120th customer will be the first one get all the three items.

What is the measure of angle y?

Answers

Answer:

y =50°

Step-by-step explanation:

40°+90°+y = 180° {the sum of angle of triangle is 180°}

or, 130°+ y = 180°

or, y = 180°-130°

or, y =50°

The value of the measure of an angle y in a triangle would be 50 degrees.

Used the concept of angle in a triangle that states,

The sum of all three interior angles in a triangle gives 180 degrees.

Given that,

A triangle is shown in the attached figure.

Here, the triangle shown in the image is a right-angle triangle.

Hence, a measure of an angle = 90 degree

And, the second measure of an angle = 40 degree

So, the sum of interior angles in a triangle gives 180 degrees.

Hence,

40° + 90° + y = 180°

Solve for y,

130° + y = 180°

y = 180° - 130°

Therefore, the value of y is,

y = 50 degree

A movie theater runs its films continuously. One movie runs for 85 minutes and a second runs for 110 minutes. The theater has a 5-minute intermission after each​ movie, at which point the movie is shown again. If both movies start at​ noon, when will the two movies start again at the same​ time?

Answers

Answer:

10:30PM on the next day

Step-by-step explanation:

First movie = 85mins

intermission = 5mins

  Total time = 90mins which is 1:30PM

so the first movie will start again at  1:30PM, which is at the interval of 90minutes and it will run continuously.

Similarly the second movie is 110 minutes long + 5mins intermission which is 115minutes

Time = 1:55PM

so the second movie starts again at 1:55PM and runs continuously at an interval of 115minutes.

We are interested to find when both the movie will start again at the same time, this will be least common multiple of 90 and 115.

LCM of 90,115 = 2070

Therefore after 2070minutes movie will start again at the same time.

2070mins = 34hours and 30 minutes

adding this with noon

10:30PM on the next day.

Which is an equation of the line with slope 1/2 that contains (–4, 7)?

Answers

Answer:

y=(-1/2)x-1

Step-by-step explanation:

hope it helps and plz give me Brainliest plz  

Equation of line is y = 1/2x + 9 which passes through the point (-4, 7) and has slope 1/2.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

We have to given that;

Point on the line = (-4, 7).

And, The slope of the line = 1/2

Since, The equation of line passes through the point (- 4, 7).

and, Slope of the line is,

⇒ m = 1/2

Hence, The equation of line is,

⇒ y - 7 = 1/2 (x - (-4))

⇒ y - 7 = 1/2 (x + 4)

⇒ y - 7 = 1/2x + 2

⇒ y = 1/2x + 2 + 7

⇒ y = 1/2x + 9

Cos function is to do adjacent (side length that is next to angle) over the hypotenuse

Tan function is to do Opposite over Adjacent,

These are the inverse of each one

Sec is hypotenuse over opposite (inverse of Sin)

Cosec is hypotenuse over adjacent (Inverse of Cos)
