Answer: In algebra, a quadratic equation (from the Latin quadratus for " square ") is any equation having the form where x represents an unknown, and a, b, and c represent known numbers, with a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no term.
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Hey there !!!
the question is incomplete the full question is Which of the following statements is TRUE/CORRECT about Quadratic Equations? A quadratic equation is _____
with options
A) an expression with a single variable and degree 2
B) an equation with a single variable and degree 2
c) an equation with only degree to 2
D) an equation with single variable only
and the correct answer is B
because Quadratic Equation states that An equation with one variable and degree 2 is a Quadratic Equation. Only option b satisfies the two basic conditions of a quadratic equation i.e. one/single variable and degree 2. Hence b is the correct answer.

20% of Aussies have blue
eyes. If 4 Aussies in a play
group have blue eyes, how
many Aussies are in the
group?
Please help
Answer:
20
Step-by-step explanation:
Step 1: 4 = 20% × Y
Step 2: 4 = 20/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:
Step 3: Y = 4 × 100/20
Step 4:Y = 4 × 100 ÷ 20
Step 5: Y = 20
The number of Aussies in the group is 20
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the total number of Aussies in the group be = A
The number of Aussies in the group who has blue eyes = 4
The percentage of Aussies that have blue eyes = 20
So , the percentage equation is
20 percentage of total number of Aussies have blue eyes = 4
And ,
( 20 / 100 ) x A = 4
Multiply by 100 on both sides , we get
20A = 400
Divide by 20 on both sides , we get
A = 20
Therefore , the value of A is 20
Hence , the total number of Aussies in the group is 20

Step 1: Define
3.6y = 1.6y + 24
Step 2: Solve for y
[Subtraction Property of Equality] Subtract 1.6y on both sides: 2y = 24[Division Property of Equality] Divide 2 on both sides: y = 12Step 3: Check
Plug in y into the original equation to verify it's a solution.

she scored (6) 3-points
Answer:
4
Step-by-step explanation:
what you would do is 19-3 and get 16 then add 3 until you get 37. you would have to cout how many times you counted up 3, here we go,16,19,21,24,27,30,33,36 we have a remainder but she made 8 shots. so since we are 1 short we have to divide by 2 to get 4.

Jessica's friend Tyshaun found an account that earns 2.5 percent interest compounded annually. Tyshaun made an initial deposit of $100 into this account at the same time Jessica made a deposit of $100 into her account. After 10 years, how much more money will Tyshaun's initial deposit have earned than Jessica's initial deposit?
Answer:
Tyshaun's initial deposit have earned $28.01 more money than Jessica's initial deposit
Step-by-step explanation:
As given, Jessica's initial deposit = $100
Tyshaun initial deposit = $ 100
As given, Tyshaun account earns 2.5 percent interest compounded annually.
rate = 2.5% = 0.025
so, after t= 10 years
Payment = P[tex](1+r)^{t}[/tex] = 100[tex](1+0.025)^{10}[/tex] = 100[tex](1.025)^{10}[/tex] = 128.01
So ,
Interest = Money earned by Tayshaun - Jessica's initial deposit
= 128.01 - 100
= 28.01
∴ we get
Tyshaun's initial deposit have earned $28.01 more money than Jessica's initial deposit

After running for 5/6 of an hour, Konnor is 1/3 of the way through his run. How long will it take Konnor to finish his run if he continues at the same pace?
Answer:
2.5 hours
Step-by-step explanation:
We need to find the rate at which Konnor runs. So his speed = distance/time.
Let x be his total distance. The distance covered in 5/6 of an hour is x/3. So, his speed is x/3 ÷ 5/6 = x/3 × 6/5 = 2x/5
Now, the rest of the distance left to cover is 1 - 1/3 = 2/3. So, the remaining distance is 2x/3.
The time required to cover this distance is t = 2x/3 ÷ speed = 2x/3 ÷ 2x/5 = 2x/3 × 5/2x = 5/3 of an hour.
So, the total time required for Konnor to complete his run is 5/6 + 5/3 of an hour = 5/6 + 5/3
= (5 + 10)/6
= 15/6
= 5/2 of an hour
= 2.5 hours

Use rectangle ABCDIf mzBAC = (4x + 5)º and m CAD = (5x - 14)°, find m2CAD.
Answer:
m CAD is 41°
Step-by-step explanation:
The angles in a rectangle are 90 degrees each as the sides are perpendicular. A such, given that mzBAC = (4x + 5)º and m CAD = (5x - 14)°, then
4x + 5 + 5x - 14 = 90
Rearrange the equation
4x + 5x + 5 - 14 = 90
9x - 9 = 90
Collect like terms
9x = 90 + 9
9x = 99
Divide both sides by 9
x = 99/9
= 11
Recall that m CAD = (5x - 14)°
Substitute the value of x into the expression
Hence
m CAD = (5*11 - 14)°
= (55 - 14)°
= 41°
