Part A) 24.79 acres
1) Since that plot has an area of
And the number of units must be between 10 and 10² units.
Part A)
2) Let's convert them to the apparently plausible units, see if it fits within the given interval.
We can see that 0.03 m² does not belong to the given interval.
3) Hence, the answer is 24.79 acres.
Answer:
t2 = 2.8 hours
Step-by-step explanation:
The distance is the same for each velocity.
Formula
d1 = d2
d = r*t
Givens
r1 = 140 miles / hour
t1 = 3.2 hours
r2 = 160 miles / hour
t2 = ?
Equation
r1*t1 = r2 * t2
Solution
140 * 3.2 = 160 * t2
448 = 160* t2
448 / 160 = t2
t2 = 2.8 hours
Formula for a sphere is V = (4 ⁄ 3) π r^3
The picture shown showed the diameter.
Half of a diameter is the radius.
The radius is 2.95 yd.
Let’s plug in the values into the formula.
V = (4/3) 3.14 (2.95)^3
V = 107.48
NOW THATS THE ANSWER FOR A WHOLE SPHERE BUT YOURE LOOKING FOR THE HEMISPHERE.
So let’s divide that in half:
107.48/2 = 53.74
Your answer is B.) 53.74 yd
