Answer:

a. 36+15+15+15+15

Step-by-step explanation:

The base of the pyramid is a square. We know that all sides of a square are equal so if we multiply the two sides of the base square(6*6) we get 36.

The area of a triangle can be found with the formula (b*h)/2. If we input the given values of 5 and 6 into our equation, then (5*6)/2 is 15 and since there are 4 triangles in the square pyramid, you multiply 15 by 4 (or add 15+15+15+15), and add the 36 from the base square.

Hope this helps :)

20% of a number is xx. What is 100% of the number? .
ludmilkaskok [199]
So you said 20% is xx???
If 20% is xx or x^2 (x squared) then 100% must be 5x^2, since 20% times 5 would get you 100%.

What is the image of (-8,10) when reflected in the y-axis
Naddika [18.5K]

Answer:

(8,10)

Step-by-step explanation:

If we reflect a point over the y-axis, the x becomes opposite while the y stays the same.

So the rule here is (a,b)->(-a,b) if we are reflecting over y-axis.

So if you reflect (-8,10) over the y-axis you get (8,10).
