Answer:
Step-by-step explanation:
The basic 30-60-90 triangle ratio is:
Side opposite to 30° angle is : x
Side opposite to 60° angle is : x √3
Side opposite to 90° angle is : 2x
From the diagram we learn that
x√3 = 10
∠T = 30°, Side opposite to ∠T is AC = 5.77
∠A = 90°, side opposite to ∠A is TC = 2x = 2*5.77 = 11.54
We use the formula V = length • width • height.
Since no exact numbers are given to represent the length, width, and height, we must count the boxes.
The length is 9 boxes.
The width is 3 boxes.
The height is 7 boxes.
V = ( 9 boxes)(3 boxes)(7 boxes)
V = 189 (boxes)^3
Answer:
22
Step-by-step explanation:
Given
(
+ 
i )( - i ) ← expand factors using FOIL
= ( )² - ( )² i² ← i² = - 1
= 5 - 17(- 1)
= 5 + 17
= 22
Answer:
x = 18/2
Step-by-step explanation:
Answer: 2,100 tickets
Step-by-step explanation:
105 people have arrived for the concert yet it is said that 95% of people are yet to arrive. This means that the 105 people are 5% of the tickets sold.
Assume the total number of tickets sold is x:
5% * x = 105
0.05x = 105
x = 105 / 0.05
x = 2,100 tickets
