Answer:
y = 4
Step-by-step explanation:
2[2y-1]+5=19 (by PEDMAS, distribute parentheses first)
(2)(2y) - (2)(1) + 5 = 19
4y - 2 + 5 = 19
4y +3 = 19 (subtract 3 from both sides)
4y = 19 - 3
4y = 16 (divide both sides by 4)
y = 16/4
y = 4
Answer:
-3.5 < -3 1/4
Step-by-step explanation:
Since both are negative numbers in this case, we need to find the number closest to zero. But first we need to make sure both the numbers are in the same format. One is in decimal while the other is in fraction form.
-3.5 is also -3 1/2 or -3 2/4
-3 1/4 is also -3.25
seeing how -3 1/4 is closer to zero by .25, that makes it the greater number compared to -3.5
Answer:
9 cm
Step-by-step explanation:
First, we need to find the volume of the cylindrical water bottle. The volume of a cylinder is πr²h where r = radius and h = height. In this case, r = diameter / 2 = 6.5 / 2 = 3.25 and h = 21 so the volume is π * 3.25² * 21 = 221.8125π ≈ 696.84. Let's call the length of the cubic container s. The volume of the cube (which is s³) must be at least the volume of the water bottle, therefore:
s³ ≥ 696.84
∛s³ ≥ ∛696.84
s ≥ 8.86566
The smallest integer value that satisfies this is 9 cm.
