well, im assuming u meant quarter, so it would be 1.5 or 1 1/2
Answer:
Area =9π
Step-by-step explanation:
A=π times r^2
Substitite 3 in for r and get 3^2=9 then multiply by π to get 9π as your answer
Take 3 times 3 minus 2 times 5 times 2 minus 3 cubed plus 4 times negative 3
Use order of operations and answer will be
Negative 50
Answer:
(0.118, 4.882)
Step-by-step explanation:
If a motorist drives for m hours at 120km/hr, then the Distance of the motorist is expressed as;
Distance = Speed * time
da = 120m
If he drives n hours at 18km/hr;
db = 18 * n
db = 18n
Speed of the motorist altogether is expressed as;
Speed =78km/5hrs
Speed = 15.6km/hr
SInce the total distnce is 78km
120m + 18n = 78 ....1 ..... * 1
If total time is 5hrs
m + n = 5....2 ...*18
Solve simultaneously
120m + 18n = 78
18m + 18n = 90
Subtract
120m - 18m = 78-90
102m = -12
m = 0.118 hrs
m =
Since m + n = 5
n = 5 - m
= 5 - 12/102
n = 4.882
Hence (m,n) is (0.118, 4.882)
Answer:
B but am not sure tho it's probably A
