The answer is B, because it all goes in order so no need for parentheses
Answer:
the answer is not correct
there is a sign error under the radical
it should be 3^2 - 4(-8)(2) = sqrt(73) not sqrt(55i)
Step-by-step explanation:
28.0
+14.2 = 42.2 could i plz get a brainleist i really need it
Answer:
10.31 ft
Step-by-step explanation:
the base is 25 ft²
leaves 100 ft² for the 4 sides on top
so each triangle got 25ft²
the base length of the triangle is 5ft, bc it's the base length of the pyramid
so the height of the triangle is 10ft,
bc only then do we get a surface area of 25ft²
(b * h /2) for the triangle
now that we got base length and height,
let's look for the slant
we recall the pythagoras stuff to get the missing side of the triangle. but notice that we need to split the triangle in half to get a 90° angle.
leaving us with 10ft (height) and 2.5ft
slant² = 10² + 2.5²
slant² = 106.25
slant = sqrt(106.25)
slant = 10.31
Answer:
B
Step-by-step explanation:
1/2 * 1 * 2 1/2 = 1 1/4
if theres 8 half unit cubes per unit cube, then we can take the two numbers given to us and divide them by 1 1/4 or 1.25 in decimal
