H^2 = x^2 + y^2
where h is the hypotenuse, x and y are the legs.
h = 19cm
x = 12cm.
y = ?
h^2 = x^2 + y^2
y^2 = h^2 - x^2
y^2 = 19^2 - 12^2
y^2 = 361 - 144
y^2 = 217
y = sqrt(217)
y = 14.7
Letter B
Answer:
s = 25
Step-by-step explanation:
First we go from point (30, 50) to point (-10, 30).
Change in x: -10 - 30 = -40
Change in y: 30 - 50 = -20
Since a change in x of -40 results in a change in y of -20, we divide both changes by 4 to get:
a change of -10 in x results in a change of -5 in y.
Now we go from point (-10, 30) to point (-20, s).
The change in x is -20 - (-10) = -10
The corresponding chang ein y must be -5.
y = 30 - 5 = 25
Answer: s = 25

Step-by-step explanation:
The cost of the dryer would be 350. We can solve this question by using the linear equation concept.
Let the cost of the dryer be “x”
Therefore, the cost of washer would be “ (x+87) “
So, According to the question, both washer and dryer would cost :
(x) + (x+87) = 787
2x + 87 = 787
2x = 787-87
2x = 700
x = 700/2
x = 350.
So, the cost of dryer is 350.
Cost of washer can be calculated as follows :
x + 87
put the value of x
350 + 87
= 437.
So the cost of washer is 437.
And together they cost 787.
