Answer:
x = 5 , y = 5
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values.
sin30° = 
, cos30° = 
, then
sin30°= 
= 
= ( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5
and
cos30° = 
= 
= ( cross- multiply )
2y = 10 ( divide both sides by 2 )
y = 5
Answer:
Step-by-step explanation:
Given
Balls = 1 to 4
Required
Determine the probability of selecting ball numbered at least 2
Here, we'll assume that all numbers have the same probability.
The probability of each ball will be:
So:
Recall that
--- for each ball
So, the equation becomes
Answer:
Perimeter = 22 units
Area = 30 units squared
Step-by-step explanation: To find the perimeter of this figure, add the lengths of the rectangle's four sides (5+6+5+6=22). To find the area of this figure, multiply the length and width of the rectangle (5x6=30).
Number of pounds purchased multiplied by price per pound equals the total $ spent.
x= # pumpkin pounds purchased
0.49x=$73.50
Divide both sides by 0.49
x=150 pumpkin pounds purchased
Hope this helps! :)
