Answer C $0.08
Step-by-step explanation:
20.99/(π*9*9)=20.99/254.44=0.08
Answer:
Number must be added = 160
Step-by-step explanation:
First we need to find LCM of 10,12,16 and 18.
LCM of 10,12,16 and 18 = 720
Let us write the multiplication table of 720
720, 1440, 2160, 2880 .................
We need to find the least number that must be added to 2000 so that the sum is divided exactly by 10,12,16 and 18 .
The number greater than 2000 is 2160.
Difference = 2160 - 2000 = 160
Number must be added = 160

B. 1/4 cup
C. 3/4 cup
D. 4/5 cup
Answer:
Option B
Step-by-step explanation:
Given that milk and cream are mixed together for a recipe. The total volume of the mixture is 1 cup.
Let x cups of milk be mixed with 1 cup of cream
Total fat in the mixture = 0.02x+0.18
=6% of x+1 = 0.06(x+1)
i.e. 0.02x+0.18 =0.06x+0.06
0.04x = 0.12
x =3
So 3 cups of milk and 1 cup of cream would be mixed
Or B) 1/4 cup cream would be mixed

Answer:
It takes 3 seconds over the interval [0,3]
Step-by-step explanation:
To find when the roller coaster reaches the ground, find when d=0.
To solve divide each term by 16 and factor:
Solve for t by setting each factor to 0.
t-3=0 so t=3
t+3=0 so t=-3
This means the car is in the air from 0 to 3 second.
The time interval will be 0<t<3 or (0, 3)
A interval is a set of real numbers that contains all real numbers lying between any two numbers of the set.
Given:
d = 144 – 16t²
Now,
d>0
144 – 16t²>0
144>16t²
144/16>t²
9>t²
t<±3
Since, timecan't be negative.
So, t<3
Hence, the interval for which Greg’s car moving in the air is, 0<t<3 or (0, 3).
