Answer:
Step-by-step explanation:
Percent: The percent is the number with the % symbol: 20%.
Base: The base is the whole amount, which in this case is unknown.
Amount: The amount based on the percent is 40
Base = unknown
One cubic centimeter is 1 mL. 1000 cubic centimeters is 1 liter. 525 cm3 is .525 liters.
Given :
Sunflower produce approximately 50 seeds per flower.
If one ounce of sunflower seeds contain an average of 72 seeds.
To Find :
How many flowers are needed to produce 2 pounds of seeds.
Solution :
1 pound = 16 ounces .
So , 2 pound = 32 ounces .
Number of seeds in 2 pounds of seeds, n = 32×72 = 2304 .
Number of flowers are :
So , approximate number of flower required are 46.
Hence, this is the required solution.
Answer:
3.2 hours
Step-by-step explanation:
12 workers * 4 hours = 48 worker hours
15 workers * x hours = 48 worker hours
48 /15 =3.2 hours
Answer:
The radius of the cone is 9cm
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cone
The volume of a cone is expressed as
V=1/3(πr²h)
We were told that the radius r and the height h are equal
I.e r=h
Substituting h=r in the formula we have
V= 1/3(πr²*r)
V =1/3(πr³)
To find the radius r let us substitute our given 763.02cm³ (note we assume unit in cm)
763.02= 1/3(3.142r³)
763.02= (3.142r³)/3
763.02*3=3.142r³
2289.06=3.142r³
r³=2289.06/3.142
r³= 728.54
r= ³√728.54
r= 8.99cm
≈r= 9cm
