The two solutions to the given quadratic equation are 2i/3, -2i/3 and they are both complex solutions.
Hence, option C is the correct answer.
What are the solutions to the quadratic equation?Given the equation; 9x² + 4 = 0
First, we subtract 4 from both sides.
9x² + 4 = 0
9x² = -4
x² = -4/9
Take the square roots of both sides
x = ±√(-4/9)
Rewrite -4/9 as (2i/3)²
x = ±√(2i/3)²
x = ±(2i/3)
Hence,
x = 2i/3, -2i/3
Therefore the two solutions to the given quadratic equation are 2i/3, -2i/3 and they are both complex solutions.
Hence, option C is the correct answer.

the supplement of an angle is 113 degrees what is the measure of the angle ?
A protractor is used to measure angles in degrees (°). With the aid of a protractor, one may measure and calculate angles in terms of degrees.
What is the measure of angle?Through the use of a protractor, angles are measured in degrees (°). In order to calculate or draw angles in terms of degrees, a protractor is a measuring tool that is utilised. Using a protractor, for instance, we can observe that the black arrow in the image below crosses the 90° line at 100°. Thus, the angle has a 100° measurement.
Generally speaking, supplementary angles are those where the total of two angles is greater than 180 degrees. A supplement to another angle is stated to exist for each of the angles. By deducting an angle's complement from 180 degrees, we can calculate its value.
A 113 degree angle's complement is a 67 degree angle.
Therefore, the answer is 67 degree.

What is the linear equation in one variable?
A linear equation in one variable is an equation in which the highest power of the variable is 1. A linear equation in one variable can be written in the form of y = mx + b, where m is the slope and b is the y-intercept. The graph of a linear equation in one variable is a straight line.
6 + 3/(x + 1) = 0
3/x+1 = -6

Sophia is going to invest in an account paying an interest rate of 3.4% compounded monthly. How much would Sophia need to invest, to the nearest dollar, for the value of the account to reach $1,450 in 14 years?
Answer:
To calculate the amount Sophia needs to invest to reach a certain value in a specific time, given an interest rate compounded monthly, we can use the formula:
A = P(1 + r/n)^(nt)
Where:
A = the future value of the investment
P = the initial principal or investment amount
r = the annual interest rate (expressed as a decimal)
n = the number of times the interest is compounded per year
t = the number of years the investment is held
Since the interest is compounded monthly, we need to divide the annual rate by 12 to find the monthly rate. So:
r/12 = 0.034/12 = 0.002833
Now we can plug in the values into the formula:
A = P(1 + 0.002833)^(12*14)
A = P(1.002833)^(168)
We know that A = $1,450 and we want to find P (the initial principal or investment amount).
So we can rearrange the equation to find P:
P = A/(1.002833)^(168)
Solving for P, we get:
P ≈ $973.99
So Sophia would need to invest around $973.99 to reach $1,450 in 14 years with an annual interest rate of 3.4% compounded monthly.

August is selling tickets for his school play.

-August sells 35 tickets and collects $160.
How many of each type of tickets did he sell?
A. 40 students and 32 adults
B. 20 students and 15 adults
C. 4 students and 5 adults
D. 15 students and 20 adults
The number of each type of tickets which August sold is equal to: B. 20 students and 15 adults.
How to determine the number of each type of tickets sold?In order to write a system of linear equations to describe this situation, we would assign variables to the number of adult tickets sold and number of student tickets sold, and then translate the word problem into an algebraic equation as follows:
Let the variable a represent the number of adult tickets sold.Let the variable s represent the number of students tickets sold.Since Adults pay $7 a ticket while students pay $5 a ticket for a total cost of $205, an algebraic equation to model is given by;
7a + 5s = 205
For the sales of 35 tickets, we have:
a + s = 35
Solving for a, we have the following:
7a + 5(35 - a) = 205
7a + 175 - 5a = 205
2a = 205 - 175
2a = 30
a = 30/2
a = 15 adult tickets.
For the number of student tickets, we have:
s = 35 - a
s = 35 - 15
s = 20 student tickets.

Which equations have the same value of x as Three-fifths (30 x minus 15) = 72? Select three options. 18 x minus 15 = 72 50 x minus 25 = 72 18 x minus 9 = 72 3 (6 x minus 3) = 72 x = 4.5
Answer:
18x - 9 = 72
3(6x - 3) = 72
x = 4.5
Step-by-step explanation:
Given equation:
[tex]\dfrac{3}{5}\left(30x-15\right)=72[/tex]
Separate the fraction:
[tex]\implies 3 \cdot \dfrac{1}{5}\left(30x-15\right)=72[/tex]
Multiply the terms inside the parentheses by 1/5:
[tex]\implies 3\left(\dfrac{1}{5}\cdot30x-\dfrac{1}{5}\cdot 15\right)=72[/tex]
[tex]\implies 3\left(6x-3\right)=72[/tex]
Expand the brackets:
[tex]\implies 3\cdot6x-3\cdot3=72[/tex]
[tex]\implies 18x-9=72[/tex]
Add 9 to both sides of the equation:
[tex]\implies 18x-9+9=72+9[/tex]
[tex]\implies 18x=81[/tex]
Divide both sides pf the equation by 18:
[tex]\implies \dfrac{18x}{18}=\dfrac{81}{18}[/tex]

What is the ratio for oil to vinegar?One part vinegar to three parts oil is the general ratio for vinaigrettes. I learned this general principle from French culinary school, which results in a somewhat acidic dressing that goes well on salads. This implies that if you start with a cup of vinegar, you would need one cup of oil.
The typical oil to vinegar ratio is three parts oil to one part vinegar or acid, however this ratio might change based on the vinegar or acid you choose and your preferences. Less oil is required the less acidic the vinegar or acid.

The bricks having same cost per brick are 1500 bricks for $1,110, 35 bricks for $25.90 and 230 bricks for $170.20. The solution has been obtained using the unitary method.
What is a unitary method?
The value of a single unit is calculated in the unitary approach before the value of the necessary number of units is determined. In order to obtain value of a single unit from a given multiple, the unitary technique is used, to put it simply.
We know that Cost per brick = number of bricks / price of bricks
Therefore, using this, we get
1500/$1110 = $1.35
1300 / $845 = $1.54
230 / $170.20 = $1.35
100 / $75 = $1.33
35 / $25.90 = $1.35

Step-by-step explanation:
You want to know the base angle in the isosceles triangle in the given figure.
Angle sumAngle ABC is the sum of its parts:
∠ABC = ∠ABD +∠DBC
The figure shows ∆DBC is equilateral, so ∠DBC = 60°. This lets us solve for the measure of angle ABD:
114° = ∠ABD +60°
54° = ∠ABD
Base angle∆ABD is isosceles, so the two base angles are congruent. The sum of angles in the triangle is 180°, so we have ...
∠ABD +∠BAD +∠BDA = 180°
54° +2(∠BAD) = 180° . . . . . . . ∠BAD =∠BDA
∠BAD = 90° -27° . . . . . . divide by 2, subtract 27°
