The answers would be z + w = -2 + 3i, z - w = 4 - 7i, and w - z = 4 + 7i after adding and subtracting two complex numbers.
What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
It is given that:
The complex numbers are:
z = 1 - 2i and w = -3 + 5i
z + w = 1 - 2i - 3 + 5i
z + w = -2 + 3i
z - w = 1 - 2i + 3 - 5i
z - w = 4 - 7i
w - z = 4 + 7i
Thus, the answers would be z + w = -2 + 3i, z - w = 4 - 7i, and w - z = 4 + 7i after adding and subtracting two complex numbers.

Bryce grows a sunflower that contains 1,354 sunflower seeds. Six people share the harvested seeds. If they share the seeds equally, how many seeds will be left over?
Answers
Answer: 4 seeds will left over.
Step-by-step explanation:
Total sunflower seeds = 1354
Number of people shared sunflower seeds equally = 6
By division operation,
Number of seeds each people will get = (Total sunflower seeds) ÷ (Number of people shared seeds equally)
[tex]= (1354) \div (6)[/tex]
[tex]=225\dfrac{4}{6}[/tex]
Hence, each people will get 256 sunflower seeds and 4 seeds will left.

Find the area of the triangle
Answers
Answer:
The area of the triangle WYX = [tex]\frac{35}{2}[/tex] = 17[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The area of the triangle WYX is [tex]\frac{1}{2}[/tex]*b*h
We need to find base (b) and height (h)
By counting from the drawing, the base which is horizontal is 7 and the height which is vertical is 5
The area of the triangle WYX is [tex]\frac{1}{2}[/tex]*b*h
The area of the triangle WYX = [tex]\frac{1}{2}[/tex]*7*5 = [tex]\frac{35}{2}[/tex] = 17[tex]\frac{1}{2}[/tex]
Which fraction is not equivalent to 9/12 ?
Answers
Answer:
16/24 is the correct answer.
Step-by-step explanation:
9/12 = 3/4
24/32 = 3/4
6/8 = 3/4
15/20 = 3/4
16/24 = 2/3
Answer:
D. 16/24
Step-by-step explanation:
If you simplify 9/12 = 3/4 because (9/12) ÷ 3
So let's just simplify the rest.
15/20 = 3/4
(15/20) ÷ 5 = 3/4
24/32 = 3/4
(24/32) ÷ 8 = 3/4
6/8 = 3/4
(6/8) ÷ 2 = 3/4
So the answer is 16/24
16/24 = 2/3

Alyssa used a scale in which 1 inch represents 100 feet. If the actual landmark has a height of 508 feet, find the height of Alyssa's model in inches.
Answers
Answer:
5.08 inches
Step-by-step explanation:
Alyssa used a scale in which 1 inch represents 100 feet. If the actual landmark has a height of 508 feet, find the height of Alyssa's model in inches.
The scale =
1 inch = 100 feet
100 feet = 1 inch
508 feet = x inches
Cross Multiply
100 × x = 508 × 1
x = 508 × 1/100
x = 5.08 inches
The height of the model is 5.08 inches

If it takes 48 seconds to complete a transaction, how many products are being purchased? If it takes 80 seconds to complete a transaction, how many products are being purchased?If it takes 80 seconds to complete a transaction, how many products are being purchased? If it takes 80 seconds to complete a transaction, how many products are being purchased? If it takes 80 seconds to complete a transaction, how many products are being purchased? If it takes 48 seconds to complete a transaction, how many products are being purchased?
Answers
Answer:
a) 4 products
b) 10 products
Step-by-step explanation:
When completing an online shopping transaction, a typical shopper takes 5 seconds to select each product and another 28 seconds to complete the check-out process.
For 1 product, the total time =
5 seconds + 28 seconds = 33 second.
We can derive an equation
Total time of transaction = 5x + 28
Where x is the number of products you are selecting
a) If it takes 48 seconds to complete a transaction, how many products are being purchased?
Total time = 5x + 28
48s = 5x + 28
5x = 48 - 28
5x = 20
x = 20/5
x = 4 items
b) If it takes 80 seconds to complete a transaction, how many products are being purchased?
Total time = 5x + 28
80s = 5x + 28
5x = 80 - 28
5x = 52
x = 52/5
x = 10 items
In whole number = 10 items

Answers
Answer:

Step-by-step explanation:
Let X represent the total number of the calculator, then we can form an equation from the explanation of the question as
X × 75/100=36
75x=36×100
Making X the subject of the formula we have,
X=3600/75
X=48
