There are a total of 48 students so what we do is divide by 4. Then you just multiply times the 3/4 left. We get 48 divided by 4 to be 12. So 12 times 3 is....36. 48-36=12. 12 girls.
Answer:
2.25π m²
Step-by-step explanation:
The area (A) of a circle is calculated using the formula
A = πr² ← r is the radius
here the diameter = 3
The radius is half the diameter, that is radius = 1.5, so
A = π × 1.5² = 2.25π m²
Answer/Step-by-step explanation:
A. Distance travelled at constant rate = 180 miles
Rate of travel (r) = distance travelled (d) /time (t)
Travel time (hrs) ==> rate of travel (miles/hr)
5 ==> 180/5 = 36
4.5 ==> 180/4.5 = 40
3 ==> 180/3 = 60
2.25 ==> 180/2.25 = 80
B. t = time travelled in hrs,
r = rate (miles/hr)
d = distance travelled = 180
Therefore, rate travelled for t hours would be:

Answer: k=225/2
Decimal form: k= 112.5
Mixed number form: k=112 1/2
First you have to write the equation...(x+7)5=30
then solve; so, x= -1
