Answer:
3,300
Step-by-step explanation:
Just took the test in edg
We know that : GF = GC + CF.Also, CF is a radius. So CF = 7.5 unitsTo
find GC we will use the Pythagorean theorem.GC² = 10² + 7.5²GC² = 100 +
56.25GC² = 156.25GC = √ 156.25GC = 12.5GF = 12.5 + 7.5 = 20Answer: d. 20 units.
Answer:
36,000 kg
Step-by-step explanation:
✔️First, find the area of the trapezium field:
Area of trapezium = ½(a + b)*h
Where,
a = 210 m
b = 190 m
h = 250 m
Area of trapezium = ½(210 + 190)*250
= ½(400)*250
= 200*250
= 50,000 m²
✔️Find the kg of barley that 50,000 m² field will produce:
10,000 m² (1 ha) produces 7,200 kg
Therefore,
50,000 m² will produce:
(50,000*7,200)/10,000
= 5*7,200
= 36,000 kg of barley
Answer:
B. 30 in, 40 in, 50 in
Step-by-step explanation:
You can try all of these combinations of side lengths in the Pythagorean theorem, or you can make use of your knowledge that the side ratios 3:4:5 form a right triangle. Only selection B (30, 40, 50) has the side lengths in that ratio.
If two of the 3 numbers have those ratios, but the third one doesn't agree, then the triangle will not be a right triangle.
___
<em>Check</em>
50^2 = 30^2 + 40^2 . . . . . the square of the hypotenuse is the sum of the squares of the two legs for a right triangle
2500 = 900 + 1600 . . . . . true
___
Attached is a graph showing the various triangles. Only the one with the dimensions of B is a right triangle.
