Answer:
There would be 40 people bowling on the second night.
Step-by-step explanation:
25 x .60 = 15
60% of 25 is 15.
25 + 15 = 40
Answer:
2nd choice
Step-by-step explanation:
all angles of a triangle must have the sum of 180⁰
72+74+44=180
Answer:
h = 4.22 cm
Step-by-step explanation:
Mathematically, we have the volume of a cylinder as;
V = pie * r^2 * h
We have it that the radius is 6 cm
V = pie * 6^2 * h
for the sphere, we have it that;
V = 4/3 * pie * r^3
V = 4/3 * pie * 4.5^3
We can proceed to equate both volumes;
pie * 6^2 * h = 5/3 * pie * 4.5^3
pie on both sides cancel out
6^2h = 5/3 * 4.5^3
36h = 151.875
h = 151.875/36
h = 4.22 cm
C) Quick way:
3x^2+6x+6=0 ---> x^2+2x+2=0,
sum of solutions is the 'x' coefficient multiplied by -1: (-1+i)+(-1-i)=-2-->2
Product is the independent term: (-1+i)(=1+i) = (-1)^2-i^2 = 1+1=2
Takes longer to write it down!
Answer:
The equations have the same slope but different y-intercepts. This means the lines are parallel and there is no solution (since they do not intersect).
