Arianna and Aryanna went out to lunch over the weekend. They decided to eat at the cheesecake factory in ridge hill. their bill came out to 40$. if they wanted to leave a 20% tip for there waitress how much will the tip be

Answers

Answer 1

Answer:

Step-by-step explanation:

First we need to find 20% of their bill-$40.

So we write a proportion with fractions.

20/100 = x/40

Then we cross multiply. So 40 and 20 will get multiplied, and 100 and x will get multiplied. We will get this:

800 = 100x

Divide both sides by 100 to solve this.

Then we will get:

$8 = x or x = $8

Now that we know 20% of the bill this will also represent the tip. Our tip is $8.

Is experimental and practical is same ,if no so tell difference ?

Answers

Step-by-step explanation:

math question ? really ?

while it is true, as the other answer indicated, that experimental and practical are not the same, but the meaning of the words is different to what the other answer suggested.

please read the question again.

this is about "experimental" vs. "practical".

so, we are only dealing with adjectives (describing associated nouns).

something is "experimental", if it already exists, but it is not clear yet, if it will fulfill its intended purpose. only time and experience in using and applying that thing will tell us.

example : experimental drugs.

something is "practical" on the other hand, if we are not wondering about the effects of the existing thing but its usability. it is "practical", if this thing or method or operation guideline or ... is not too complicated to do, and any potentially necessary resources are relatively easily available and obtainable.

Answer:

y=-2x+4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-2-2)/(3-1)

m=-4/(2)

m=-4/2

m=-2

y-y1=m(x-x1)

y-2=-2(x-1)

y-2=-2x+2

y=-2x+2+2

y=-2x+4

Distance formula =

x={sq rt} of (x2-x1)^2 + (y2-y1)^2

{sq rt} (-7-5)^2+ (-7-9)^2 = {sq rt} (-12)^2 + (-16)^2 = {sq rt}

144+256= {sq rt} 400

{sq rt} 400 = 20

Answers

Answer:

a>4 or a < 8

Step-by-step explanation:

We can start with the inequality on the left

-a + 2(4+3a) > 28

expand using the distributive property

-a + 8 + 6a > 28

5a + 8 > 28

subtract 8 from both sides to isolate the variable and its coefficient

5a > 20

divide both sides by 5 to isolate a

a > 4

moving on to the inequality on the right

2a - (3a+4) > -12

treat the minus sign as a -1

2a + (-1)(3a+4) > - 12

expand

2a - 3a - 4 > - 12

-a - 4 > -12

add 4 to both sides to isolate a and its coefficient

-a > - 8

multiply both sides by -1 but change the sign because we are multiplying by a negative number

a < 8

2. If y varies directly as x, and y= 0.9 when x= 0.3. Find y when x= 1.5, the constant of variation and the equation of variation.

3. If y varies inversely as, and y= 10 when x=1/2. Find x when y= 3, the constant of variation and the equation of variation.

4. If v varies jointly as w and u, and v=14 when w=7 and u=13. Find v when w=3/4 and u=6, the constant of variation and the equation of variation.

5. If m varies directly as n and inversely as p and m=9 when n=2 and p=1/3. Find m when n=1/2 and =1/3, the constant of variation and the equation of variation.

Answers

1. This is a ratio question in disguise.

By parts of the question: "When y varies directly with x" -> y/x

"if y=8 when x=4" -> y/x = 8/4

"how do you find y when x=5" -> y/x = 8/4 = y/5

so -y = 8x5/4 = 10

She accepted her request but of course like every other kid, they had to get permission. She later came home and asked their parents if she could come to the party, short answer...no. Samantha tries to argue with them but, no luck. Later in the evening, Samantha was getting frustrated. Then she thought I could sneak out of the house while mom and dad are sleeping., and so thats what she did. A few hours later she started to get ready, wearing her witch costume. She quietly sneaks out of her room into the hallway, the wooden floor creaking. She gets to the front door, walks out of the house, and slowly shuts the door. She looked around, seeing the streets were completely empty. She began walking down the street, slowly realizing she didn't know where she was going. After about a few minutes she was completely lost: didn't know her way back home, nor which direction to take. The fear of being alone crept up to her. All of a sudden she hears a bit of laughter coming from behind her. She turns around, her eyes widening as she sees a tall man in a clown costume, looking at her with a sinister smile. Samantha didn't know what to do, she quickly started to walk away, the clown follows. She yells, "Back off creep!". She started running, so did the clown chasing after her. She yelled and screamed for help, nobody was around. She gets to a nearby park losing sight of the clown. She hides behind a tree not knowing what to do. She peeks around seeing him, wandering around looking for her. She was trembling in fear, being cold and alone. Then she heard sirens in the distance and the clown immediately runs away. 1) Find the probability of rolling anumber greater than 3 on a standardnumber cube.
