Great Escape bought a vintage bicycle for $3,000. They marked it up

slega [8]

Answer:

Solution,

CP of a bicycle=$3000

Marked up=40%

Now,

→40% of $3000

→40/100x$3000

→$1200

→$3000+$1200=$4200

Again,

Discount(d)=30%

→30%of $4200

→30/100x$4200

→$1260

Hence, the discount price of the bicycle is $1260

Find the area of the trapezoid by decomposing it into other shapes. A) 48 cm2 B) 55 cm2 C) 66 cm2 D) 96 cm2

snow_tiger [21]

Answer:

The answer is B.

Step-by-step explanation:

You have to use area of trapezoid formula, A = 1/2×(a+b)×h where a, b are the side lengths and h is height :

$area = \frac{1}{2} \times (a + b) \times h$

$let \: a = 6,b = 16,h = 5$

$area = \frac{1}{2} \times (6 + 16) \times 5$

$area = \frac{1}{2} \times 22 \times 5$

$area = 11 \times 5$

$area = 55 \: {cm}^{2}$
