Answer:
dresses
Step-by-step explanation:
We are given that
Lucy sews dress in 3/4 hours= of dress
Lucy sews at constant rate.
We have to find the number of dresses sewed by Lucy in hour.
To find number of dress sewed by Lucy in 1 hour we will use unitary method.
By using unitary method
Lucy sews in 3/4 hours= dress
Lucy sews in 1 hour=
Lucy sews in 1 hour=
Lucy sews in 1 hour= dresses
Hence, Lucy sews dresses in 1 hour.
For two linear equations to have exactly one solution, their gradient/slope must be different. That's the only requirement. For example y=x intersects with -1/3x - 8 at (-6, -6). So one that has only one solution could be y=x+5.
For two linear equations to have no solutions they must have the same gradient/slope but not be the same equation. Hence, y = -1/3x + 8 would never intersect with y = -1/3x - 8.
For two linear equations to have infinite solutions, they must be the same line or simplify to give the same line. I.e. 3y = -x - 8 would have infinitely many solutions with the above graph.
Answer:
3 games
Step-by-step explanation:
The computation of the maximum number of games that he could buy is shown below:
= Amount available - already spent
= $75 - $28
= $47
If each game cost $15
So, the maximum no of games is
= $47 ÷ $15
= 3.133
= 3 games

Answer:
2 %
Step-by-step explanation:
Money borrowed, Principal, P = $ 700
time of investment, T = 3 years
Total interest paid, Simple interest, S.I = $ 42
Let the rate of interest is R.
Use the formula for simple interest.
By substituting the values
4200 = 2100 R
R = 2 %
Thus, the rate of interest is 2%.
