Answer:
The ladder from the base of the building is 5.18 ft (Approx)
Step-by-step explanation:
As given
A ladder that is 20 ft. Long is leaning against the side of a building.
If the angle formed between the ladder and the ground is 75.
Now using the trignometric property .
As shown in the figure.
Base = CB
Hypotenuse = AC = 20 ft.
Put in the trignometric identity .
Put in the above
CB = 0.259 × 20
CB = 5.18 ft (Approx)
Therefore the ladder from the base of the building is 5.18 ft (Approx) .
Answer:
The minimum number of cups she must sell to reach her goal=43 cups
Step-by-step explanation:
Total earnings=Total Lemonade sales-Supplies expenditure
where;
Total earnings=$40
Total Lemonade sales=Price per cup×Number of cups sold(n)=(0.7×n)=0.7n
Supplies Expenditure=0.23 per cup=(0.23×n)=0.23n
Replacing;
40=0.7n+0.23n
Inequality; 0.7n+0.23n=40
Solving;
0.93n=40
n=40/0.93)=43 cups
The minimum number of cups she must sell to reach her goal=n=43 cups
