So,
In order to find numbers that are in between 3/8 and 6/7, Lucy must make common denominators first.
LCM of 8 and 7: 56
Multiply each fraction by the appropriate form of 1:
We can immediately see that any fraction with a numerator between 21 and 48 and a denominator of 56 will fit into the criteria Lucy needs.
The correct option is B.

Hello! Remember you need to write complete questions in order to get good and exact answers. Here we know nothing about the students so I can only help you providing the correct steps to find <em>the product of a number and eight is 104:</em>
<em />
Let that number be 
, then the statement can be written in a mathematical language as follows:
Finally, <em>the unknown number is 13</em>
Answer:
C, 23 square feet
Step-by-step explanation:
we can start by finding the area of Stephan's playroom
this is modeled by
11*11=121
Next we can find the area of Carmen's playroom
we know his playroom is 1ft longer and wider
so the dimensions of his playroom is 12 by 12
the area can be modeled by
12*12=144
now we just need to subtract
144-121=23
Number 1 is c as your answer and number 2 is 93.33
Hello,
1)
tan (a-b)=(tan a - tan b)/(1+tan a tan b)
15=45-30
tan 45°= (√2/2)/(√2/2)=1
tan 30°=(1/2)/(√3/2)=√3/3
tan (45°-30°)= (1-√3/3)/(1+1*√3/3)=(3-√3)/(3+√3)=(3-√3)²/6=2-√3
tan (-105°)=tan (75°)= tan (60°+15°)=(tan 60+tan15°)/(1-tan 60°*tan 15°)
tan 15°=2-√3
tan 60°=√3°
tan (-105°)=(√3+2-√3)/(1-√3*(2-√3))=2/(1-2√3+3)=1/(2-√3)=2+√3
