Answer:
3
Step-by-step explanation:
In this case, Luis has 6 quarters, and 3 dimes. 6 - 3 = 3, and it works out to the following:
6 • 0.25 = 1.50
3 • 0.10 = 0.30
1.50 + 0.30 = 1.80
Step-by-step explanation:
Since the last reflecting off glass
Answer:
for x = 14, the given ABCD is a RECTANGLE.
Step-by-step explanation:
Given : ABCD is a quadrilateral.
E is the intersection points of the diagonal AC and BD.
AE = x+10, and BE= 3x -18
Now, as we know:
IN A RECTANGLES , DIAGONALS BISECT EACH OTHER.
⇒ E is the mid point of AC and BD respectively.
⇒ AE = BE
⇒ x+10 = 3 x - 18
or, 10 + 18 = 3 x - x
or, 2 x = 28
or, x = 28/2 = 14 ⇒ x = 14
Hence, for x = 14, the given ABCD is a RECTANGLE.
The function representing the graph is 5m+40
Answer:
see below
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin alpha = opp side/ hyp
sin alpha = 12/ 15
Take the inverse sin of each side
sin^-1 sin alpha = sin^-1 (12/15)
alpha = 53.13010235
sin beta = opp side/ hyp
sin beta = 9 /15
Take the inverse sin of each side
sin^-1 sin beta = sin^-1 (9/15)
beta = 36.86989765
