Out of the 100 people in the sample, 72% said they preferred pizza. That 72% should be the same for the whole school.
1500 × .72 = 1080
about 1080 students in the school prefer pizza
Answer:
A
Step-by-step explanation:
2x2.5x3= 15
2x2.5x4.5=22.5
2.5x3x4=30
2.5x2x4=20
Answer:
18.25
Step-by-step explanation:
1/4 = 0.25
The surface area of a sphere by definition is given by:
A = 4 * π * r ^ 2
Where,
r: radius of the sphere.
Substituting the values we have:
294 = 4 * π * r ^ 2
We cleared the radio:
r ^ 2 = (294) / (4 * π)
Answer:
An equation that I could use to find the dome's radius is:
A. r2 = 294 square feet ÷ 4π
I'm not to sure if I know the other ones but number 12th Is 6
Step-by-step explanation:
Since the two lines intersect at point Q(x,y) the x & y values of both lines must be equal at point Q. so 3x+14=7x-10. Solving for x yields x = 6.
