What is the additive inverse of the complex number –8 3i? –8 – 3i –8 3i 8 – 3i 8 3i
The additive inverse of a number gives zero. The additive inverse of the complex number -8+3i is 8-3i.
What is additive inverse?The additive inverse of a number is the other number which when added to the initial number gives the output as zero.
As we know about the additive inverse, therefore, we need a number that will return zero when added to the complex number.
The additive inverse of the complex number -8+3i will be,
[tex](-8+3i) + (8-3i) = 0[/tex]
Thus, the additive inverse of the complex number -8+3i is 8-3i.

Mrs. Bailey is knitting a striped blanket for her granddaughter. She made of the blanket pink, of the blanket green, and the rest
of the blanket was white. Which fraction represents the white part of the blanket?
A) 3/4 of the blanket
B) 5/8 of the blanket
C) 1/2 of the blanket
D) 3/8 of the blanket
...
Answer:
D) 3/8 of the blanket
Step-by-step explanation:
Adding up the pink and green parts, then subtracting it from 1 would yield the white area. Finding a common denominator gives: 2/8 + 3/8 which is 5/8. So 5/8 of the blanket is not white meaning that 3/8 of the blanket is white.

A new spiral notebook contains 10 fewer sheets than a new
composition book. The total number of sheets of paper in
2 new spiral notebooks and 5 new composition books is
540. Which system of equations can be used to find s, the
number of sheets of paper in one new spiral, and c, the
number of sheets in one new composition book?
s - c = 10
2s – 5c = 540
c - s = 10
2c + 5s = 540
S + c= 540
2s - 5c = 10
c - s = 10
5c + 2s = 540
multiply quantity of each and add them together to get total of 540
2s + 5c = 540 or 5c + 2s = 540
The difference in pages is 19 so you would subtract: c-s = 10
answer would be
d: c-s = 10
5c + 2s = 540

The resistance of a wire varies directly with its length and inversely with the square of its diameter. If 100 feet of wire with diameter 0.01 inch has a resistance of 10 ohms, what is the resistance of 140 feet of the same type of wire if its diameter is 0.01 inch
Answer:
14 ohms
Step-by-step explanation:
The resistance varies directly with length, so increasing the length by a factor will increase the resistance by the same factor.
__
The length of the wire increased by a factor of 1.4 from 100 ft to 140 ft. That means the resistance will increase by a factor of 1.4 from 10 ohms to 14 ohms. (The diameter did not change.)
The longer wire will have a resistance of 14 ohms.

Rhys will tile the rectangle below to find it’s area. Q: How many unit squares with side length 1/10 foot will Rhys use to tile the rectangle? The sides of the rectangle: 3/10 foot and 4/5 foot. Answers: 24 unit squares, 18 unit squares, 12 unit squares, and 7 unit squares.
Using the areas of the rectangle and of the square, it is found that 24 unit squares will be used to tile the rectangle.
What is the area of a square?
The area of a square of side l is given by the square of l, that is:
A(l) = l².
In this problem, we have that [tex]l = \frac{1}{10}[/tex], hence the area is given by:
[tex]A = \left(\frac{1}{10}\right)^2 = \frac{1}{100} = 0.01[/tex]
What is the area of a rectangle?The area of a rectangle of length l and width w is given by the multiplication of the measures, that is:
A = lw.
In this problem, we have that the measures are:
[tex]l = \frac{3}{10}, w = \frac{4}{5}[/tex]
Hence:
[tex]A = lw = \frac{3}{10} \times \frac{4}{5} = \frac{12}{50} = \frac{24}{100} = 0.24[/tex]
The area of the rectangle is 24 times the area of the square, hence 24 unit squares will be used to tile the rectangle.

How to calculate the area of plane shapes?A square is a plane shape with 4 sides
The formula for calculating the area of the square is expressed as:
A = l^2
Given
side length of a square = 1/10 foot
A = (1/10)² = 1/100 = 0.01 square foot
Determine the area of the rectangle
Area = length * width
Area = 3/10 * 4/5
Area = 12/50 = 6/25
Area = 0.24 square foot
Take the ratio of both areas
Ratio = 0.24/0.01
Ratio = 24 units
