a) 
b) 
c) 
d) 
Answer:
Step-by-step explanation:
Given
Required
Determine its equivalent
Start by writing y - z in bracket;
becomes
When - is used as divide, it is equivalent to /
The given expression can then be rewritten as
Hence;
<em /><em> is equivalent to </em><em />
Answer: 2 the first one
Step-by-step explanation:
(0.10)m +10.00 = 23.80
0.10m = 13.80
m=13.80/0.10
m = 138 minutes
Answer:
A. 1.2 yd
Step-by-step explanation:
We are informed that Mr.Reddrick has a 74 total yards of red and blue felt to distribute to students in his art class. Moreover, we also have the information that each of his 20 students gets 2.5 yards of blue felt for the project. This implies that the total blue felt distributed is;
20*2.5 = 50 yards
The remainder is the total red felt left for distribution;
74 - 50 = 24 yards
Since we have 20 students, each one of them receives;
24/20 = 1.2 yd
Answer:
Problems like this all have the same solution method.
If you have n letters, you start with n!. Then you divide by k! for each distinct set of k letters.
This is purely mechanical. E.g., if you have
AAAAABBBBCCC
DEFGHIJKLMNOP
there are 25 letters, and groups of 5 4 and 3
The answer is 25! / (5! 4! 3!). See, all you need to do is count the letters and then count how many times any letters are repeated. Then you can just write down the answer.
Once you know that, these problems are really, really easy.
