Answer:
$620
Step-by-step explanation:
Let the price of refridgerator be "r"
price of washer be "w"
and
price of dryer be "d"
Total 1800, that means, we can write:
r + w + d = 1800
Also, refrigerator cost 250 more than washer, so we can write:
r = w + 250
The dryer is HALF (0.5) of washer, so we can write:
d = 0.5w
Now, we replace equation1 with equation 2 & 3, so get an equation in "w" and solve for w:
r + w + d = 1800
w + 250 + w + 0.5w = 1800
2.5w + 250 = 1800
2.5w = 1800 - 250
2.5w = 1550
w = 1550/2.5
w = 620
Thus, the washer costed $620
The top is a triangle with sides 7 and 5.4 Use the Pythagorean theorem to find the 3rd length.
3rd sides = sqt(7^2 + 5^2( = sqrt(49+25) = sqrt(74)
This side is the base of the lower rectangle.
The dotted line is the hypotenuse of a right triangle.
Use the Pythagorean theorem to solve.
sqrt(10^2 + sqrt(74)^2) = sqrt(174)
The dotted line = sqrt(174)
In converting between polar and rectangular coordinates, we take
so that the equation becomes
which we can rewrite as
so the answer is C.
