What are the the values of x and y that satisfy this equation?
(x + yi) + (4+9i) = 9-4i
Answer: Option A; x = 5, y = -13
Step-by-step explanation:
We have the equation:
(x + yi) + (4+9i) = 9-4i
Solving the left side we have:
x + y*i + 4 + 9*i = 9 - 4*i
(x + 4) + (y + 9)*i = 9 - 4*i
The real part is x + 4, and this must be equal to the real part in the right that is 9, then:
x + 4 = 9
x = 9 - 4 = 5
x = 5
And the imaginary part in the left needs to be equal to the imaginary part in the right, then:
y + 9 = -4
y = -4 - 9 = -13
y = -13
then the solution is x = 5, y = -13
The correct option is A

Step-by-step explanation:
there are five nickels and seven dimes in your pocket. four of the nickels and six of the dines are canadian. the others are US currency. you randomly select a coin from your pocket. what is the probability it is a nickel or it is Canadian currency?
AND ITS SUPPOSED TO BE A FRACTION
There is a 4/12 or 1/3 percent that I would get a Canadian currency nickel and a 1/12 percent that it would be a USA nickel. For how I got the 4/12 fraction, I just add all the coins together and see how much nickels are from Canadian currency and then that will be the fraction. Since there is only one nickel that is from USA out of 12, then it‘ll be 1/12 as the fraction.

What is the distance between the longest dog in the shortest dog Short 7 over 8 longest 3 over 8 what is the difference
Answer:
The distance between the longest dog and the shortest dog is 4 over 8 ( [tex]\frac{4}{8}[/tex] ) OR 1 over 2 ( [tex]\frac{1}{2}[/tex] )
Step-by-step explanation:
From the question,
Short is 7 over 8, that is,
Short = [tex]\frac{7}{8}[/tex]
and longest is 3 over 8, that is
Longest = [tex]\frac{3}{8}[/tex]
The distance between the longest dog and the shortest dog can be determined by finding the difference between the fractions. That is,
[tex]\frac{7}{8} - \frac{3}{8} = \frac{7 - 3}{8}[/tex]
[tex]= \frac{4}{8}[/tex]
[tex]= \frac{1}{2}[/tex]
Hence, the distance between the longest dog and the shortest dog is 4 over 8 ( [tex]\frac{4}{8}[/tex] ) OR 1 over 2 ( [tex]\frac{1}{2}[/tex] ).

Keisha reads a label on a measuring cup that shows 16 fluid ounces is the same as 2 cups.
What is the unit rate of fluid ounces to 1 cup?
Answer:
16/2 = 8
1 cup = 8 fluid ounces
The unit rate of the fluid ounces to 1 cup is given by the equation
A = 8 fluid ounces
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The unit rate of fluid ounces to 2 cups by Keisha = 16 fluid ounces
So, the equation will be
Unit rate of fluid ounces to 1 cup = unit rate of fluid ounces to 2 cups / 2
Substituting the values in the equation , we get
The unit rate of fluid ounces to 1 cup A = 16 / 2
On simplifying the equation , we get
The unit rate of fluid ounces to 1 cup A = 8 cups
Therefore , the value of A is 8 fluid ounces
Hence , the unit rate is 8 fluid ounces

The diameter of a semicircular table is 10 cm. Find the cost of polishing the semicircular table top at ₹ 3.50 per sq.cm
Answer:
₹ 137.46
Step-by-step explanation:
Here, we want to find a cost
Firstly, we need the area of the semi circular table
The area is by the formula;
A = pi/2 * r^2
Since d = 10
r = d/2 = 10/2 = 5
A is thus;
3.142/2 * 5^2 = 39.275 sq. cm
Cost per sq cm is 3.50
cost of 39.275 sq. cm will be
39.275 * 3.50 = 137.4625

Step-by-step explanation:
8*4 is 32 8*9 is 72
so, it is 8
since it is distributive property 8(4+9)
Answer:
8
Step-by-step explanation:
1) simplify the equation
32+72=104
104=4x+9x (distibute the "x")
104=13x
x=8

The school store is selling notebooks for $1.50 and T-shirts for $10.00 to raise money for the school. They have a goal of raising $250 to buy supplies for the science lab. If they have sold 60 notebooks, how many T-shirts will they need to sell to reavh their goal?
Answer:
They will need to sell 16 T-shirts to reach their goal
Step-by-step explanation:
Let us solve the question
∵ The school store is selling notebooks for $1.50 and T-shirts for $10.00
∴ The price of each notebook = 1.50 dollars
∴ The price of each T-shirt = 10.00 dollars
∵ They have sold 60 notebooks
∴ The number of notebooks sold = 60
∵ They have a goal of raising $250
∴ The total money they want to earn = 250 dollars
Assume that they will sell x T-shirt to reach their goal
Multiply the no. of notebooks by the price of each and the no. of T-shirts by the price of each, then add the two products and equate the sum by 250
∵ 1.50 (60) + 10.00 (x) = 250
∴ 90 + 10x = 250
→ Subtract 90 from both sides
∵ 90 - 90 + 10x = 250 - 90
∴ 10x = 160
→ Divide both sides by 10 to find x
∴ x = 16
∴ The number of T-shirts = 16
∴ They will need to sell 16 T-shirts to reach their goal
