Answer:
15
Step-by-step explanation:
x/3 + 3 = 8
x/3 + 9/3 = 8
x + 9 = 24
x = 15
Answer:
Manuel would be correct, the volumes would be equal.
Step-by-step explanation:
The formulae for finding the volume of pyramids and cones both include dividing three (multiplying by
).
Square pyramid formula:
×B×h where B is the area of the base. By plugging in numbers we have that B=314.159 and h=5. 314.159×
×5=523.5983.
Cone formula: The basic formula is the same:
×B×h, but the area of the base is found using the circle formula of π×r². For the cone we have B=314.159 and h=5. 314.159×
×5=523.5983.
Since both of these formulas came up with the same answer, we can conclude that Cone W has the same volume as Pyramid X, which is Manuel's answer.
Answer:
y=2/7x+19/7
Step-by-step explanation:
Slope = m = (y₂-y₁)/(x₂-x₁) = (5-3)/(8-1) = 2/7
Therefore, our equation so far is y=2/7x+b where we can calculate b, the y-intercept by plugging in one of our given points [I used (1,3)]:
y=2/7x+b
3=2/7(1)+b
3=2/7+b
21/7=2/7+b
19/7=b
Therefore, our final equation is y=2/7x+19/7
Answer:
47 - 2n
Step-by-step explanation:
An algebraic expression is an idea of representing numbers using letters or alphabet.
From the question above,
The variable = n
twice the number = 2× n = 2n
Translating:
47 - 2n
b= 227 so yea your welcome you can do the rest sorry
Step-by-step explanation:
908÷5= b or 227
