A family spent $65 on dinner and left a 20% tip. What was the total cost of their meal?

A. $85

B. $78

C. $67

D. $13

Answers

Answer 1

Answer: B, $78

Step-by-step explanation:

If the tip is 20% of the dinner cost, then we have to first find what is 20% of 65.

20% x 65 = 13. So the tip for the dinner is 13 dollars.

Now we have to add it to the original dinner cost.

65 + 13 = 78.

Therefore, the total cost of their meal is 78 dollars. So the answer is B, $78!

Answer 2

Answer: A

Step-by-step explanation:

the total cost of their meal it usally means how much in total so we add 65+20 = 85

Answer: 9

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle.

[tex]a^2+b^2=c^2[/tex]

[tex](\sqrt{63}) ^2+x^2=12^2\\63+x^2=144\\x^2=81\\x=9[/tex]

X=9

A squared + b squared = c squared

C is the hypotenuse (the side opposite of the right angle)

X*2 + square root of 63 squared = 12*2
Squaring 63 would cancel out with the square root. You are left with x*2 + 63 = 144. 144-63= 81. X*2=81 ; square root both sides. You are now left with x=9

Ben wants to go fishing on the lake

A boat rents for $12 per hour, and a rod and reel rent for $20 per day.

If Ben wants to spend no more than $80, how many hours can he soend fishing on the boat

Answers

Answer: Ben can only rent the boat for 5 hours.

Step-by-step explanation:

You have to set up an equation. It would be 20 + 12h = 80

20+12x=80

12x=80-20

Then divide both sides 12x=60

And you get 5

Ben can spend at most 6 hours (72 dollars) being on the boat.

Now if you wanna include the rod and reel, Ben can spend 29 hours (24 hours from the rod and reel, and 5 hours on the boat) Which all adds up to 80

The numbers 1-6 are written on slips of paper and placed in a bag. Megan draws two numbers in a row without replacement. What is the probability of Megan selecting an even number followed by a 3?

A) 1/6

B) 1/10

Answers

I’m pretty sure it would be 1/6

The probability of Megan selecting an even number followed by a 3 will be 1/10. Then the correct option is B.

What is probability?

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

Paper slips with the numbers 1-6 are collected in a bag. Without substitution, Megan draws two numbers consecutively.

The probability is given as,

P = (1/6) x (3/5)

P = (1/2) x (1/5)

P = 1/10

The probability of Megan selecting an even number followed by a 3 will be 1/10. Then the correct option is B.
