Answer:
the visible number of cubes is 7
Step-by-step explanation:
Assuming that there are no hidden cubes, the # of visible cubes is 7
Hello!
In our triangle, c is the hypotenuse. We are given an adjacent side length to our angle. This means we will use the cosine. Let's find it first.
cos54≈0.59
This gives us the equation below.
0.59=9/c
0.59c=9
c≈15.25
Therefore, c is equal to about 15.25
I hope this helps!
Answer:
y = 1/2x -1.5
Step-by-step explanation:
The equation of a line is typically written as y = mx + b.
m is the slope of the line, while b is the y-intercept. y is the y-coordinate and x is the x-coordinate.
Since it indicated that the line has a slope of 1/2, we can substitute the m in the equation with 1/2.
y = 1/2x + b
In order to find the intercept of the line, we use the equation of a line to substitute the y-coordinate and x-coordinate of (-3,-3) to discover the y-intercept of b.
-3 = 1/2(-3) + b
One half of -3 is -1.5.
-3 = -1.5 + b
Add -1.5 to both sides of the equation.
-3 = -1.5 + b
+1.5 +1.5
-1.5 = b
Since we found the y-intercept, we can now place it into our equation.
y = 1/2x -1.5 and that's the answer!
now, "A" is the accumulated amount, including the earned interest, how much interest was it earned? well, is just A - P.
Answer:
C
Step-by-step explanation:
ZC is an altitude, thus ∠ZCY = 90°
The sum of the3 angles in a triangle = 180°
Sum the 3 angles in ΔCYZ and equate to 180
90 + 5x + 22 + 12x = 180 ← simplify left side
17x + 112 = 180 ( subtract f112 from both sides )
17x = 68 ( divide both sides by 17)
x = 4
Hence
∠WZC = 12x = 12 × 4 = 48° → C
