We know that total surface area is the area of of the base + area of all the walls + area of the top
here we are working with a pyramid whose base is a square but the wall are four triangles
as triangles are connected on the top , there would be no top area ( as the top would be a point ( where all four triangles are being join )
so total area is = area of base + area of four walls ( triangles here )
Answer:
4(11+8+28)
Step-by-step explanation:
44 + 32 + 112
4(11+8+28)
I found the GCF of all three numbers.
Hope this helps :)
Let's begin by assigning a letter to represent our unknown: x = # of toppings to be added to each pizza Now let's come up with expressions for the cost of each pizza with its toppings: Palanxio's Pizza: 6.80 + 0.90x Guido's Pizza: 7.30 + 0.65x Now let's equate the costs of both pizzas and solve for our unknown (x): 6.80 + 0.90x = 7.30 + 0.65x 0.90x - 0.65x = 7.30 - 6.80 0.25x = 0.50 x = 0.50/0.25 x = 2 toppings to be added to each pizza Finally, we can verify our answer by plugging it back into our equation and see if both costs are the same: 6.80 + 0.90x = 7.30 + 0.65x [equation] 6.80 + 0.90(2) = 7.30 + 0.65(2) [answer plug-in] 6.80 + 1.80 = 7.30 + 1.30 $8.60 = $8.60 [both costs are the same] Since both costs are the same, we are confident that our answer is correct.
Answer: 38
Step-by-step explanation:
To solve this problem, you are simply going to plug in the values for the numbers into the equation so it would look like this:
7(3)+8(4)-5(6)
Electronics- 40%
industrial design- 20%
civil engineering- 100%
not sure but best of luck :)
