Leni [432]

Answer:

Step-by-step explanation:

price of tv and sales tax = 1.0688×$189 = $202.0032 ≅ $202.00

4 years = 3×365 days + 366 days = 1461 days

cost of electricity = 1461 days × $0.06/day = $87.66

lifetime cost = purchase price + electricity + repairs

ra1l [238]

Answer:

$ 154

Step-by-step explanation

Let the value of suitcase=x

x × 4.5% = 6.93 (converted the question into equation)

x × $\frac{4.5}{100}$ = 6.93 (converted the percentage into fraction)

x = 6.93 x $\frac{100}{4.5}$ (took reciprocal of 4.5/100 after moving it to the other side of the equation)

x = $\frac{693}{4.5}$ (multiplied the values)

x = 154 $ (simplified the fraction)

PQ and JK are corresponding sides.

QR and KL are corresponding sides.

$\dfrac{PQ}{JK} = \dfrac{QR}{KL}$

$\dfrac{25}{5} = \dfrac{t}{1.5}$

$5t = 25 \times 1.5$

$t = 5 \times 1.5$
