Answer:
13.8
Step-by-step explanation:
We are given that
When two triangles are similar then
WZ=15 , ZY=12
XY=11
We have to find the WV.
Substitute the values then we get
We have to round to the nearest tenth of final answer.
The Hundredth place =5 which is equal to 5.Therefore, 1 will be added tenth place 7 and all digits on left side remain same and digit on right side of tenth place replace by zero.
Therefore, WV=13.8
216.4 is the total cost added up.
198.77 would be the subtraction of the answer above with the hardware supplies but subtraction would be wrong so you'd have to divide, dividing would get you to 0.0814, the you'll have to divide the decimal by 100 giving you 0.0815.
Do the same steps above but with the paint and hardware.
52.91/216.4 gives you 0.244501, rounded up would give you 0.000245.
Add those two totals together to get your answer, 0.081745.
Sorry if I'm wrong. Hope this helps!
Answer:
Step-by-step explanation:
The additive inverse of a number (its "opposite") is what you add to the given number to get a sum of zero.

Answer:
A) 3.2
Step-by-step explanation:
In this geometry, all of the right triangles are similar. This means side lengths are proportional:
short side/hypotenuse = x/8 = 8/20
x = 8×8/20 = 64/20
x = 3.2
Answer:
73.21 m
71.68°
Step-by-step explanation:
Like the question has stated, we're to solve this using Pythagoras theorem.
Pythagoras theorem states that
opp² + adj² = hyp²
From the question, we're asked to find the hypotenuse, being given the opposite side and the adjacent. The opposite side is the center of the Ferris wheel above the ground, and that is 69.5 m. While the adjacent is the distance of the second anchor.
Succinctly put, we have
69.5² + 23² = hyp²
4830.25 + 529 = hyp²
hyp² = 5359.25
hyp = √5359.25
hyp = 73.21 meters.
Therefore, the length of the cable is 73.21 meters long.
To get the angle, we use the formula
Sin Φ = opp/hyp
Sin Φ = 69.5 / 73.21
Sin Φ = 0.9493
Φ = sin^-1 0.9493
Φ = 71.68°
Therefore, the angle of elevation to the center of the Ferris wheel is 71.68°
