Suppose that b and c are points on the number line . if bc = 10 and b lies at 3 , where could c be located?

katrin [286]

C would be located around 3.3

Bc=10 meaning b x c= 10
B lies at 3
(Opposite of time is division as you probably already know) so 10/3 is 3.3

(I’m sorry if this wrong but hope it is not and you understand it)

Two identical square pyramids were joined at their bases to form the composite figure below. 2 square pyramids have a base of 24

Airida [17]

Answer:

$8[\frac{1}{2}(24)(5)]$ cm²

Step-by-step explanation:

Surface area of the composite figure = Surface area of the lateral surfaces of the given pyramids

Lateral surface area of a square pyramid = 4

Therefore, lateral surface area of the pyramid

= $4[\frac{1}{2}(24)(5)]$

Now lateral surface area of the composite figure = 2(lateral surface area of two pyramids)

= $8[\frac{1}{2}(24)(5)]$

Therefore, Expression for the surface area of the given composite figure is,

$8[\frac{1}{2}(24)(5)]$ cm²
