Answer:
m = 0
Step-by-step explanation:
distribute
7 + 35m + 2m = 7 +2m
add 35m + 2m
7 + 37m = 7 + 2m
subtract 2 from 37m
7 + 35m = 7
subtract 7 from 7
35m = 0
0 ÷ 35 = 0
so technically the answer is 0
I'm not 100% sure but I do believe this is right
Answer:
B is the awnser
Step-by-step explanation:
Answer:

b) +343
Step-by-step explanation:
a) 10 shares - loss $40
1 share --- ?
? = 40 / 10 = 4 decrease
b) each week 7 members increase for 49 weeks
so total increase = 7 * 49 = 343
Answer:
14.8%
Step-by-step explanation:
Step 1: Given data
True value for the heat of vaporization of water (ΔH°vap(T)): 540 cal/g
Experimental value for the heat of vaporization of water (ΔH°vap(E)): 620 cal/g
Step 2: Calculate the experimental percent error
To determine the experimental percent error we will use the following expression.
%E = |ΔH°vap(T) - ΔH°vap(E)|/ΔH°vap(T) × 100%
%E = |540 cal/g - 620 cal/g|/540 cal/g × 100%
%E = 14.8%
Answer:
The percent increase is 30%
Step-by-step explanation:
First find the difference
6.50 - 5.00 = 1.50
Divide by the original cost
1.50 / 5.00
.3
Change to percent
.3 = 30%
The percent increase is 30%
