Answer:
52.15
Step-by-step explanation:
52.149
Since last digit is 9,
The tenth digit, which is 4 gets rounded to 5.
Therefore answer: 52.15
256² = (256)·(256) = 65,536
Answer:
21 CM
24.5 cm
31.5 cm
Step-by-step explanation:
Measure of each side = (ratio of each side / sum of ratios) x perimeter
Sum of ratios = 6 + 7 + 9 = 22
6/22 x 77 = 21 cm
7/22 x 77 = 24.5 cm
9/22 x 77 = 31.5 cm
Y = mx + b
1.) -6x + y = 4
Move variable x over to the other side by adding 6x.
y = 6x + 4
2.) -y - 2x = 4
Move variable x over to the other side by adding 2x.
-y = 2x + 4
Divide the whole thing by -1 because y needs to be positive and alone.
y = -2x - 4
Answer:

a) $4110
Step-by-step explanation:
Let x represent number of rain coats and C(x) represent total cost to produce new line of rain coats.
We have been given that the fixed costs of $570 to set up for production, and variable costs of $30 per jacket.
The cost of x jackets would be
.
The total cost of x jackets would be variable cost of x jackets plus fixed costs that is $570.
Therefore, the total cost of producing x rain coats would be
.
To find the total cost of producing 118 rain coats, we will substitute
in the above equation as:



Therefore, the total cost of producing 118 rain coats is $4110 and option 'a' is the correct choice.
