Answer:
A = 30 unit^2
Step-by-step explanation:
To find the area of the triangle
A = 1/2 b*h where b is the length of the base and h is the height
b = 12 and h =5
A = 1/2 (12*5)
A = 1/2 *60
A = 30 unit^2

Answer:
d) 54 ft = 1645.92 cm
Step-by-step explanation:
Given : 54 ft.
To find : Approximately how many centimeters are in 54 ft.
Solution : We have given 54 ft.
We know
1 ft = 30.48 cm .
54 ft = 54 * 30.48 cm.
54 ft = 1645.92 cm.
Therefore, d) 54 ft = 1645.92 cm.
Answer:
Step-by-step explanation:
Let 25% solution is x liters, then 50% solution is (80 - x) liters.
<u>Acid content is going to be same:</u>
- 0.25x + 0.5(80 - x) = 80*0.4
- 0.25x - 0.5x + 40 = 32
- 0.25x = 8
- x = 8/0.25
- x = 32 liters
So 32 liters of 25% solution and 80 - 32 = 48 liters of 50% solution
