Options :
A cookies per pound
B. O pounds per hour
c. cookies per hour
D. hours per cookie
Answer: C.) Cookies per hour
Step-by-step explanation:
Given the following :
Number of cookies baked = 225 cookies
Total time taken = 5 hours
Amount of sugar used = 8 pounds
Tara divides 225 by 5; 225 / 5 = 45
Rate gives the amount or number of times something occurs within a given period, Hence
The rate obtained by Tara corresponds to the ratio of ; (Total cookies baked / total time taken) = (225 / 5), this translates to the amount or number of cookies baked within an hour.

≈ 39.3 in²
Step-by-step explanation:
The area of the sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 10² × 
= 
≈ 39.3 in² ( to 1 dec. place )
Answer:
Step-by-step explanation:
a = 2i + 3j + zk
b = xi + 1j + 4k
Given a X b = 6i -14j +5k
a X b = | i j k|
|2 3 z|
|x 1 4|
a X b = i(12-z) - j(8 - xz) + k(2-3x) = 6i -14j +5k
equate the coefficients of i , j and k
12- z = 6; implies z = 6
8 - xz = -14 implies 8 - 6x = -14
2-3x = 5 implies 2 - 3x = 5 implies x = -1
