Answer:
The number of hot beverages = 45 and number of cold beverages = 180
Step-by-step explanation:
We have to write the equation of hot and cold beverages and find how many of each were sold.
Cost of cold beverage = $1.50
Cost of hot beverage = $2.00
The total cost of beverages on that day totaled to be $360.
We are also told that the number of cold beverages sold is 4 times as many hot beverages.
Let number of hot beverages = x
Cold beverages = 4x
Total cost = $360
= 360
8x = 360
x = 
x = 45
The number of hot beverages = 45 and number of cold beverages = 180
According to the text, 1 bag of grass seed = 1/6 of the lawn. So if this is right, then it will take 6 bags of grass seeds to cover 1 lawn.
Answer:
73.4 cm^2
Step-by-step explanation:
The equation is :
πr^2
Substitute the radius in:
π(5)^2
Solve:
Area of full circle = 25π
(Note : leave this answer in terms of 'pi' so it is easier to handle
Next, find the area of the sector
The equation for this is:
(angle/360) x πr^2
Substitute the values in:
(80/360) x π(5)^2
Solve :
Area of sector = (50/9)π
Now, find the area of the triangle:
1/2 absinC
Substitute the values in:
1/2(5)(5) x sin(80) = 12.31009691
Subtract this answer from the area of the sector
Answer = 5.14319607
Subtract this from the area of the whole circle
Answer = 73.39662073
To the nearest tenth, that would be 73.4 cm^2

Answer:
Step-by-step explanation:
{L = W + 5
{166 = 2L + 2W
166 = 2[W + 5] + 2W
166 = 2W + 10 + 2W
166 = 10 + 4W
- 10 - 10
