The capacity is the same as the amount because it refers to the amount of what is inside the object. Lets say you have a bag of chips it refers to the amount inside the bag of chips.
1. b. Commutative Property of Addition
Reason: There is no multiplication used
2. a. 60
Reason: 36 + 24 = 60
3. b. 3d + 9
Reason: Simplification and combining like terms :)
4. b. 4,-1
Reason: Coefficients are the numbers in front of variables
5. b. 36m + 9
Reason: Just use distributive property (multiply 9 into both terms inside parenthesis)
6. b. 95.488
Reason: b = 165.288 - 39.7 - 30.1
7. The question is cut off, unanswerable
8. c. 5a, -3a
Reason: Like terms are things you can combine. So technically the answers could be b. and c. but just go with c. because they have variables.
9. b. 16
Reason: just add 4 to both sides to get the "a" by itself
Best of luck to you!
Answer:
Step-by-step explanation:
let wind velocity=x
speed of plane=y
(x+y)*4=808
x+y=808/4=202 ...(1)
(y-x)*4=488
y-x=122 ...(2)
add (1) and (2)
2y=202+122=324
y=324/2=162
from (1)
x+162=202
x=202-162=40
wind velocity=40 m/hr
speed of plane=162 m/hr
Given
- f(n) values for n=1,2,3,4
- possible candidates for the function
Solution:
Method: Evaluate some of the values, for each function. A function with ANY value not matching the given f(n) values will be rejected.
N=1, f(n)=4
f(1)=4-3(1-1)=4
f(1)=4+3^(1+1)=4+3^2=4+9=13 ≠ 4 [rejected]
f(1)=4(3^(n-1))=4(3^0)=4
f(1)=3(4^(n-1))=3(4^0)=3*1=3 [rejected]
N=2, f(n)=12
f(1)=4-3(2-1)=4-3(1)=1 ≠ 12 [rejected]
[rejected]
f(1)=4(3^(2-1)=4*3^1=4*3=12
[rejected]
Will need to check one more to be sure
N=3, f(n)=3
[rejected]
[rejected]
f(3)=4(3^(n-1))=4(3^(3-1))=4(3^2)=4*9=36 [Good]
[rejected]
Solution: f(n)=4(3^(n-1))
Depends on the answers it gives you, you can do 50 + 2 or (10 x 5) + 2 >.< That is how I learned anyway and I think thats what you mean
