If we know the quadratic formula, the quadratic formula is
x = [-b ± √(b²- 4ac)] / 2a
Gosh! So overwhelming! But let's look at the composition of a quadratic equation:
ax² + bx + c = 0
And we have 6x² - 3x = 1. So, what do we do? We need to put this quadratic equation into an easy form to find the value of a, b, and c to plug in to the equation.
We can just minus one on both sides to get this:
6x² - 3x - 1 = 0
Is it in the form of ax² + bx + c? Yes! a = 6, b = -3, and c = -1. Now, all we have to do is plug it into the quadratic formula.
x = [-b ± √(b²- 4ac)] / 2a
x = [-(-3) ± √((-3)²- 4(6)(-1))] / 2(6)
[3 ± √(9- 4(6)(-1))] / 12
[3 ± √(9 + 24)] / 12
[3 ± √(33)] / 12
At this point, we should just use a calculator, and recognize we have two answers because of the plus-or-minus sign! (or this sign: ±)
[3 ± √(33)] / 12
1) [3 + √(33)] / 12 = 0.73 approximately
2) [3 - √(33)] / 12 = -0.23 approximately
So, x=0.73 and x= -0.23.
1. A student has a rectangular block. It is 2 cm wide, 3 cm tall, and 25 cm long. It has a
mass of 600 g. Determine the density of the block to the nearest unit.
8.9
Answer:
20 gcm^3
Step-by-step explanation:
Density = mass / volume
Volume = 3 X 2 X 25 = 30 cm
600 / 30 = 20

A certain television is advertised as a 21-inch TV (the diagonal length). If the height of the TV is 13 inches, how wide is the TV? Round to the nearest tenth of an inch.
Answer:
16.50
Step-by-step explanation:
The width of the TV will be equal to 16.49 inches.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides.
Given that a certain television is advertised as a 21-inch TV (the diagonal length). If the height of the TV is 13 inches.
The width of the TV will be calculated as,
W = √ ( 21² - 13² )
W = √ ( 441 - 169 )
W = √272
W = 16.49 inches
Therefore, the width of the TV will be equal to 16.49 inches.

51.68 feet / hourCovert to inches / min:
1 foot = 12 in, 1 hour = 60 min51.68 feet / hour =51.68 * 12 in / 60 min = 51.68 * 1/5 in / min = 10.336 in/ minWhat is the slope of a line perpendicular to the line with equation y = 5x – 2?
5
−15
–2
–5
Answer:
- [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 5x - 2 ← is in slope- intercept form
with slope m = 5
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{5}[/tex]

Out of the 90 customers at Eva's boutique35 wore a size extra-large. What is the probability that a randomly selected customer wore a size extra-large? Write your answer as a fraction or whole number. P(extra - large) =
Answer: 7/18
Step-by-step explanation:
Number of customers at Eva's boutique = 90
Number of customers who wore a size extra-large = 35
The probability that a randomly selected customer wore a size extra-large will be:
= Number of customers who wore a size extra-large / Number of customers at Eva's boutique
= 35 / 90
= 7/18
Therefore, the probability that a randomly selected customer wore a size extra large is 7/18.

Answer:
The answer is -72/5.... also as 14.4
Answer:
Step-by-step explanation: first put in the value for x, 8(-6) -5y=24
Then solve from there, 8x-6= -48
-48-5y=24
-5y=24+48 ( becomes pos when transferred to this side, since it turns to the opposite direction )
Now, -5y=72
Decide both sides by -5 and then
Y = -14.4 or -14 2/5
Barbara sells iced tea for $1.49 per bottle and water for $1.25 per bottle. She wrote an equation to find the number of bottles she needs to sell to earn $100. 1.25x + 1.49 = 100 What error did Barbara make in writing the equation? the number of bottles of water.
Answer:
she didnt write an x next to the 1.49 in her equation. she is writing an equation for how many bottles she is selling but according to her equation she is selling water for 1.25$ times x amount of bottles and selling only one ice tea

.Find the area of the figure
Answer:
Area of the figure = 171 in²
Step-by-step explanation:
Composite figure given in the picture comprises of three figures, two right triangles and one rectangle.
Area of the composite figure = Area of two right triangles + Area of the rectangle at the center
Area of one right triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(12)(9)[/tex]
= 54 in²
Area of the rectangle = Length × Width
= 7 × 9
= 63 in²
Area of the composite figure = 2(54) + 63
= 108 + 63
= 171 in²
