Answer:
The lengths of the three sides are 10 cm, 9.49 cm and 3.16 cm
Step-by-step explanation:
Let
c ------> the length of the hypotenuse of a right triangle
x -----> the length of one leg
y -----> the length of the other leg
we know that
-----> equation A (Pythagoras Theorem)
----> equation B
-----> equation C
Substitute equation B and equation C in equation A and solve for y
Find the value of x
therefore
The lengths of the three sides are 10 cm, 9.49 cm and 3.16 cm
You can't answer the question without lengths to reference
14% of $15,500 is $2,170. $15,500 minus $2,170 is $13,330.
When the car is on sale, the price is reduced from $15,500 to $13,330.
The answer is x = -5, it looks like you got it right.
Area = length X width
A = L(12 ft) x W(9 ft) but since the cost of carpet is given in square yards not square feet we need to convert
A = (12 ft)(1 yd/3 ft) x (9 ft)(1 yd/3 ft) 1 yard = 3 feet so 1 foot = 1/3 yard
A = 4 yd x 3 yd divide by 3 ft which cancels the original ft and leaves yd's
A = 12 square yards
Cost = Area x price per yard
Cost = 12 sq yd X $35.00/ sq yd multiply and the sq yd's cancel leaving just cost in dollars
Cost = $420.00
