The sales tax in Kadisha's state is 5%. Kadisha says she computes a 15% tip by multiplying the tax shown on her bill by 3. For a

bill with a tax charge of $.38, Kadisha's tip is $.38 times 3 = $1.14. Why does Kadisha's method work?

Explanation:

Kadisha's method works because 15% is 3 times 5%, and both amounts are computed on the amount of the bill before tax is added.

Answer:

<h2>$40,250</h2>

Step-by-step explanation:

Amount he will pay in the next five years = Principal + Interest

Given Principal =  $35,000

Simple Interest = PRT/100

R is the rate = 3%

T is the time in years = 5years

SI = 35,000 * 3 * 5/100

SI =  $5,250

Amount =  $35,000  +  $5,250

Amount =  $40,250

Ruben will have to pay $40,250 after 5years

1. We are given:
a^2 = 64

The only a which squared gives you 64 is 8. The perimeter of an 8 by 8 square will be 32. Half of that is 16. Now, let's see what we can do. We can set up:
4a = 16

Obviously, each side length has to be 4. So, the area of this square will be 16 units².

2. Let n equal her son's age. So, her age right now will be (S = her age):
S = 18n
1 year ago it was:
S-1 = 3n

We have 2 equations, let's substitute. We can rewrite this as:
18n-1 = 3n
Solve for n:
15n-1=0
n= \frac{1}{15}

We know the value of n, which is her son's age. So, her son is 1/15 of a year old or about 24 days old.

Problem:
andreyandreev [35.5K]
5(n-4)=(4n-12)

First: Distribute 5 into n and -4.
5(n-4)=(5n)+(5*-4)= 5n-20.

Second: Subtract 4n from both sides to eliminate the variable from the right side of the equation.

(5n-20)=(4n-12)

n-20=-12

Next: Add 20 to both sides to eliminate the constant from the left side of the equation.

n-20=-12

n=8

The unknown number is 8.

Person A is breathing five times as fast as person B. Compare the graphs of the breathing of the two people over time.
hammer [34]

Answer:

A

Step-by-step explanation:

Focus on what the question is telling you, as it's given to you in the question. It's saying five times, which means "×5" the number of person B, so it'll always be 5 times quicker, since they're breathing more times in a certain period of time than person B.

Hopefully this helped!

15 and 17 pls.. 15 points!!!!
Maurinko [17]

Step-by-step explanation:

15) 50 ÷ 2 = 25

17) Mean = 301, Mode = 40-50

(10+20) ÷ 2 = 15, (20+30) ÷ 2 = 25, (30+40) ÷ 2 = 35

(40+50) ÷ 2 = 45, (50+60) ÷ 2 = 55, (60+70) ÷ 2 = 65

(70+80) ÷ 2 = 75

• 15×4 = 60, 25×8 = 200, 35×10 = 350, 45×12 = 540

55×10 = 550, 65×4 = 260, 75×2 = 150

Mean = (60+200+350+540+550+260+150) ÷ 7

= 2110 ÷ 7

= 301.4285....

= 301

Mode : the highest frequency
