Answer:
14 =x
Step-by-step explanation:
We can use ratios to solve
5 loaves x loaves
------------- = ---------------
2.5 hours 7 hours
5 * 7 = 2.5 x
Divide by 2.5
35/2.5 = 2.5x/2.5
14 =x
So, 1/3 of something is 21.
1/3 of x is not the full x: we know that the x is 21 and even more. So, it must be bigger than 21, since it has 21 and something else (and since 21 is not negative): the solution MUST be greater than 21.
Answer:
I believe the answer is <em>C</em>
Step-by-step explanation:
Answer:
A = 11²/{4π}
Step-by-step explanation:
The circumference equation is C = 2πr. Thus, r = C / (2π), and:
C² (22π)² 2²11²π² 11²
r² = ---------- so, if C = 22π units, r² = -------------- = ---------------- = -------------
(2π)² (2π)^4 (2π)²(2π)² (2π)²
11²π²
or r² = ---------------
The area equation for a circle is A = πr² which here is π·11²/(2π)²
This reduces to 11²/{4π}
Answer:
80 millilitres (mL)
Step-by-step explanation:
Multiply by 1000 because there are 1000 mL in 1 L
