What is the surface area of the square pyramid represented by the net? 5ft 3ft 3ft 5ft 5ft 5ft
Answer:
39 ft²
Step-by-step explanation:
I assume the base is a square 3 ft by 3 ft, and the height of each triangular side is 5 ft.
SA = s² + 4 × bh/2
SA = (3 ft)² + 4 × (3 ft)(5 ft)/2
SA = 9 ft² + 30 ft²
SA = 39 ft²
If my assumption is incorrect, then the correct answer will be different, but I don't have a figure that I can see.

What is the domain of this graph?
Answer:
Domain: all real numbers
Step-by-step explanation:
This graph is a parabola. It's equation looks like it should be:
y = x^2 - 1
If you have a graph and are looking for the domain, you are determining where the graph exists. For what x's the graph exists. If you have the equation then the domain is what x's may be put into the equation. There are no limitations on what numbers can go into this equation so the domain is all real numbers.
There are several ways to write the domain is all real numbers, set builder notation and interval notation. But the main idea is that it is all real numbers.

An equation is shown
X + 1 = 9x - 3
What is the solution?
Answer:
Step-by-step explanation: x + 1 = 9x - 3
x + 1 = 9x - 3
(minus x from both sides)
1 = 8x -3
(add 3 to both sides)
4 = 8x
(flip the equation)
8x = 4
(divide both sides by 8)
x = 4/8
x = 1/2 or 0.5

Answer:
would multiply everything by the common denominator of 4
-3/4m - 1/2 = 2 + 1/4m....multiply everything by 4 and u get :
-3m - 2 = 8 + m
that will get rid of the fractions....but u could multiply by -4 ...giving u :

48 g of 0.8 kg in fractions
Answer:
3/50
Step-by-step explanation:
First,convert the 0.8kg to grams
To do this, first state formula 1kg equals 1000g
Solution
1kg equals 1000g
thus,0.8kg equals 0.8 x 1000g which further equals 800g
Since both are now in grams,they can be divided without many problems so
48g/800g,using 8 to divide through & grams cancelling out
6/100,using 2 to divide through finally becomes
