Answer:
Step-by-step explanation:
A quantitative variable is the one which is represented numerically and not with words.
Hence option (C) is the quantitative variable as servings per box are represented by numbers. (eg. if in a box of 16 cookies, 1 serving = 1 cookie, then the servings per box will be 16)
Write each number in complex polar form:
When you multiply two exponential expression with the same base (here, that's <em>e</em>), you end up adding the exponents, so that
so the angle of the product <em>zw</em> is 90°.
First round
137,638=100,000
52,091=50,000
Then add to get the estamate
100,000
+
50,000
150,000
Then to get the real answer add
1
137,638
+
52091
189,729
Answer: 72
Because the picture shows that there's a 90 degree angle in the bottom. We know that the bottom triangle is a 45-45-90 triangle. So the length of one side is 18 because a 45 45 90 triangle has two sides that are equivalent (x) and one side that is x
. So now that we know the length of one side is 18, we know the lengths of all 4 sides. Adding them up ( 18 + 18 + 18 + 18) gives 72, which is the perimeter.
Answer:
∅ = 67.71°
Step-by-step explanation:
The flag pole is 20 ft tall is casting a shadow that is 8.2 ft long .At what angle is the sun hitting the ground. The illustration forms a right angle triangle.
The right angle triangle has an hypotenuse, opposite and adjacent sides. The flag height forms the opposite side. The shadow forms the adjacent side . The angle the sun is hitting the ground can be using SOHCAHTOA principle.
using Tan
tan ∅ = opposite / adjacent
tan ∅ = 20/8.2
tan ∅ = 2.4390243902
∅ = tan⁻¹ 2.4390243902
∅ = 67.7063708403
∅ = 67.71°
