The shipping fee is $30
1. 12%×250
= 250×12/100
= 2.5 ×12
= 5/2×12
=60/2
=30
Answer:
3
Step-by-step explanation:
area of square=l*b so
81=3x multiply 3x
81=9x^2
81/9=x^2
9=x^2
=x
3=x
Now, assuming is a vertical parabola, so the squared variable is the "x", let's do some checking.
Remark
The general formula is fraction * solid food = amount
Total amount = 1/2 * 3 oz + 3/4 * 3 oz + 1/3 * 2 oz
Total amount = 3/2 oz + (9/4) oz + 2/3 oz
The lowest common denominator of 2 4 and 3 = 12
Total amount = 3*6/2*6 + 9*3/4*3 + 2*4/3*4
Total amount = 18/12 + 27/12 + 8/12
Total amount = 53/12 = 4 5/12 <<< Answer oz of food.
4.42 oz of food <<<< Answer
Answer:
x = - 12, y = - 9
Step-by-step explanation:
Given
- 4 + 3i - x + yi = 8 - 6i
Simplify left side by collecting like terms and equate like coefficients with the terms on the right side, that is
- 4 - x + i(3 + y) = 8 - 6i, thus
3 + y = - 6 ( subtract 3 from both sides ) ← equating imaginary parts
y = - 9, then
- 4 - x = 8 ( add 4 from both sides ) ← equating real parts
- x = 12 ( multiply both sides by - 1 )
x = - 12
