Answer:
see below
Step-by-step explanation:
whenever there is negative number being squared, you need to add the brackets so that you inside the - 1 in front of the number
so this step is wrong
the -9 ² , you must include the brackets to include the -1 in front of the 9
so it should be
so you will get = 1
and then you continue with other parts of the formula and you will get real solutions

Answer:
189
Step-by-step explanation:
step 1: calculate area of rectangle
Area = l × b
= 10× 15
= 150
step 2: calculate area of half a circle
Area = 1/2 (π.r²)
= 1/2 (22/7 × 5²)
=157/4
step 3: Add the area of rectangle and half a circle together
Area = 157/4 + 150
= 189.26
rounded off to the nearest whole = 189
Answer:
V = (2/9)s³
Step-by-step explanation:
The general formula for the volume of a pyramid is:
V = (1/3)(base area)(height).
Here, the length of a side of the square base is s, and so the area is A = s². For the height we use (2/3)s. Then the volume of the pyramid is:
V = (1/3)(s²)(2/3)s, or V = (2/9)s³
It will be 18 spoonfuls because you have to do 6 times 3 which is 18.
