Mathematics

Answer:

The segment area = 113.09\ unit^2

Step-by-step explanation:

Area of the segment = \frac{(\theta)}{360} \times \pi r^2,where \theta is the angle.

We can also say that 90\ degrees is covered with one segment and we have total 4 segments (quadrants),so area of the circle divided by 4 will give us the segement area of the arc.

So area \frac{\pi r^2 }{4} =\frac{\pi(12)^2}{4} = 113.09\ units^2

So the area of the segment = 113.09 \ units^2

Find the length of the segment with endpoints of (3,2) and (-3,-6).
MakcuM [25]
The formula of the length of the segment AB:
A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\|AB|=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}
We have:
A(3;\ 2)\to x_A=3;\ y_A=2\\\\B(-3;\ -6)\to x_B=-3;\ y_B=-6
Substitute:
|AB|=\sqrt{(-3-3)^2+(-6-2)^2}=\sqrt{(-6)^2+(-8)^2}\\\\=\sqrt{36+64}=\sqrt{100}=10
Answer: B) 10.

As a butcher, you sell beef in 3.5-pound packages. You anticipate needing 25 packages for the next two days. The
bekas [8.4K]

Answer:

O weight in kilograms = 25 x 3.5 ÷ 2.2

Step-by-step explanation:

As a butcher, you sell beef in 3.5-pound packages. You anticipate needing 25 packages for the next two days.

Therefore, the total number of pounds for the 25 packages =

3.5 pound packages × 25

= 87.5 pounds

We are told that : The wholesaler from whom you purchase large pieces of meat measures the weight of the beef in kilograms.

Note that:

2.2 pounds = 1 kg

Hence:

87.5 pounds =

= 87.5÷ 2.2

= 39.772727273 kg

He needs to buy 39.772727273kg from the wholesaler

The equation can you use to determine the weight of the beef, in kilograms, that you need to purchase from the wholesaler is:

O weight in kilograms = (25 x 3.5) ÷ 2.2
