<span>We know that 4 balls will make 8 caps. Than x balls will make 6 caps. We will use the proportion: 4 / 8 = x / 6. After that we will cross multiply: 8 x = 6 * 4, 8 x = 24, x = 24 : 8, x = 3. Answer: 3 balls of wills will make 6 knitted caps. I hope that my answer is helpful! Let me know if you need something more :)</span>
Answer:
Apply cosine rule:
c²=b²+a²-2ba cosC
C= pi/3 = 180/3 = 60 degrees
cosine 60 deg = 0.5
c²=2²+3²-[2×2×3×0.5]
c²=7
c=√7
c=2.645 ;length of third side of angle
Step-by-step explanation:
Answer:
15 cos(33°) m
Step-by-step explanation
Presumably m stands for meters.
If RS were 1, x would be cos(33°)
Multiply sides of triangle by 15 m
When calculating cos(33°) first make sure cos(90°) comes out zero, not -0.448...
Answer:
(5.5, -3.5)
Step-by-step explanation:
As you can see in the figure, the fourth vertex is (5.5, -3.5)
If you observe carefully the vertex given, you will see that there are two vertex with same coordinates in x axis:
- (-1.2, -3.5),
-
(-1.2, 4.4),
And one vertex has other coordinate in x axis, it is: (5.5, 4.4)
To form a rectangle, you need a fourth vertex that will have same coordinate in x than (5.5, 4.4) and same coordinate in y axis as (-1.2, -3.5),
Then the fourth vertex coordinate is (5.5, -3.5)
