To efficiently double the volume of a square pyramid, you need to double the height of the pyramid.
<span>V = (1/3)Ah where A is the area of the base. If you double the height and leave A unchanged, the volume will also be doubled (replace h with 2h in the formula).</span>
Answer: Area = 28.2m²
Step-by-step explanation: The triangle YXZ is shown in the figure below.
Area of a triangle is calculated by the formula:
According to the figure, the base of this triangle is b = 8.3m.
Height is a perpendicular line created from one side and intersecting the opposite angle.
To determine the height, use trigonometric relations to angle 68:
h = 7.3*sin(68)
h = 7.3*0.93
h = 6.8
Now, area of triangle YXZ is
A = 28.2
Area of triangle YXZ is 28.2m².
Answer:
Step-by-step explanation:
Answer: Interval notation: (−∞, 3) ( − ∞, 3) Any real number less than 3 in the shaded region on the number line will satisfy at least one of the two given inequalities. Example 4: Graph and give the interval notation equivalent: x<3 or x≥−1. x < 3 or x ≥ − 1. .
You want half of the recipe, so you want half of 3/4 of a cup.
Multiply 3/4 by 1/2 cup.
3/4×1/2=3/8 cup.
You should use 3/8 cup of milk.
Set up an equation like this, where n represents the number:
2(n + 6) = 3(n - 6)
2n + 12 = 3n - 18
-n + 12 = -18
-n = -30
n = 30
The number is 30. You can even double-check by plugging 30 into each side of the original equation and simplifying:
2(n + 6) = 3(n - 6)
2(30 + 6) = 3(30 - 6)
2(36) = 3(24)
72 = 72
Check.
