( \frac{2}{3} - \frac{1}{6} )÷( \frac{2}{5} - \frac{1}{3} )
The first thing you must do it to solve the fractions inside the parentheses first
\frac{2}{3} - \frac{1}{6} = \frac{4}{6} - \frac{1}{6} which is \frac{3}{6} or \frac{2}{3}because you must get a common denominator in order to solve. The common denominator is 6. So you must multiply in order to get 6. \frac{2}{3} *6= \frac{3}{6} Then you do the other fraction: \frac{2}{5} - \frac{1}{3}= \frac{6}{15}  - \frac{5}{15} which is \frac{1}{15} because 15 is the common denominator and you must multiply the denominator to get 15, thus, you must multiply by the same amount for the numerator. So now it is \frac{3}{6}÷\frac{1}{15} but when dividing, you just need to flip-flop the second fraction and then multiply across. Now it is \frac{3}{6} * \frac{15}{1} = \frac{45}{6} But to simplify, you find a common factor which is 3.
45÷3=15 and 6÷3=2 which is now \frac{15}{2}
You answer is C)\frac{15}{2}

A triangle has side lengths of 5 inches, 12 inches, and 15 inches. Every dimension is multiplied by 1/5 to form a new triangle.
Butoxors [25]

a = 5 in

b = 12 in

c = 15 in

the lengths of the sides a, b and c

the perimeter is P = a + b + c = 5 + 12 + 15 = 32 in

let the dimensions of the new triangle be

a1 = (1/5)*5 in

b1 = (1/5)*12 in

c1 = (1/5)*15 in

the perimeter is P1 = a1 + b1 + c1 = (1/5)5 + (1/5)12 + (1/5)15 = (1/5)(5 + 12 + 15) = (1/5)P1

P1 = (1/5)P

P1/P = 1/5 = a/a1 = b/b1 = c/c1

the ratio of the perimeters is equal to the ratio of the corresponding sides.

Write a function to represent each problem situation Carmen deposits $1000into simple interest account.The rate for the account
kolezko [41]

The function the represent the balance in the account as a function of time t is p(t) = 1000 + 40t

<h3><u>Solution:</u></h3>

Given that,

Carmen deposits $1000 into simple interest account

The rate for the account is 4%

To find: function the represent the balance in the account as a function of time t

Given is simple interest account

The formula for simple interest is given as:

S.I = \frac{ prt}{100}

Where, "p" is the principal and "r" is the rate of interest and "t" is the number of years

In simple interest,

total amount after "t" years = principal + simple interest

Here in this question, Carmen deposits $1000

p_0 = 1000

r = 4 \% = \frac{4}{100} = 0.04

Thus we can frame a function as:

total amount after "t" years = principal + simple interest

p(t) = p_0 + (p_0 \times r \times t )

p(t) = 1000 + (1000 \times 0.04)t\\\\p(t) = 1000 + 40t

Where, p(t) is the amount after "t" years and p_0 is the principal sum

Thus the function is obtained
