P(A U B) = P(A) +P(B) - P(AB) \\  \\ = \frac{7}{20} +\frac{3}{5} - \frac{21}{100} \\  \\ = \frac{35}{100} +\frac{60}{100} - \frac{21}{100}  \\  \\ =\frac{74}{100}  \\  \\ =\frac{37}{50}

A credit card company charges 18% simple interest for overdue accounts. How much interest will Kristen owe three months from now
Ber [7]

Answer: The amount that Kristen would owe three months from now is $67.5

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or the current balance.

R represents interest rate

T represents the duration for which the account is overdue in years.

From the information given,

P = 1500

R = 18%

T = 3 months = 3/12 = 0.25 year

I = (1500 × 18 × 0.25)/100 = $67.5

FromTheMoon [43]

Answer: t\in [\dfrac{1}{4},2]

Step-by-step explanation:

Given

Inequality is 4t^2\leq9t-2

Taking variables one side

\Rightarrow 4t^2-9t+2\leq0\\\Rightarrow 4t^2-8t-t+2\leq0\\\Rightarrow 4t(t-2)-1(t-2)\leq0\\\Rightarrow (4t-1)(t-2)\leq0

Using wavy curve method

t\in [\dfrac{1}{4},2]
