Answer: First term = 11r and second term= 7s
The coefficient in first term = 11
The coefficient in second term =7
Step-by-step explanation:
The given expression 11r + 7s is with two terms i.e. a binomial expression with variables r and s
Here the first term = 11r
And the coefficient of r in term =11
The second term= 7s
The coefficient of s in second term=7
The coefficients are the numbers that multiply the variables .
Step-by-step explanation:
10 × n = 360
n = 360 ÷ 10
n = 36
So, n = 36
(3 × 4) × 5 = k × (5 × 4)
12 × 5 = k × 20
60 = k × 20
k = 60 ÷ 20
k = 3
So, k = 3
Answer:
Length between the longest bolt and the shortest bolt is:
2.375 inch
If we laid one of each size bolt end to end , then the length of row of bolts is:
5.125 inch
Step-by-step explanation:
We are given that:
Martin sorted the bolts in his toolbox by size.
They measured 3/8 inch, 1/2 inch,5/8 inch, 7/8 inch, and 1 1/4 inches
longest bolt= 11/4 inches shortest bolt=3/8 inch
Difference between longest and shortest bolt= 
Now, if we lay one of each size bolt end to end then, length of row will be:

=41/8
= 5.125 inches
Answer:
40%
Step-by-step explanation:
The first step is to calculate the unit selling price
= total sales/number of units
= 200,000/50,000
= $4
The unit variable expense can be calculated as follows.
= total variable expense/number of units
= 120,000/50,000
= $2.4
The contribution margin per unit can be calculated as follows
=selling price per unit- variable cost.
= $4-$2.4
= $1.6
Therefore the contribution margin ratio can be calculated as follows.
= $1.6/$4
= 0.4×100
= 40%
The answer is B.
Reason: A squared plus B squared equals C squared
