Step-by-step explanation:

Answer:

(3 +/- i*sqrt(151) / 20 (no real solutions)

Step-by-step explanation:

10x^2 - 6x + 4 = -3x

Add 3x to both sides

10x^2 - 6x + 4 + 3x = -3x + 3x

10x^2 - 6x + 4 + 3x = 0

Add like terms

10x^2 - 3x + 4 = 0

We have to use quadratic formula to find the answers

For this equation, a = 10, b = -3 and c = 4

Note: +/- is plus or minus

Quadratic formula:

x = (-b +/- sqrt(b^2 - 4ac)) / 2a

x = (-(-3) +/- sqrt(-3^2 - 4(10)(4))) / 2(10)

x = (3 +/- sqrt(9 - 160)) / 20

x = (3 +/- sqrt(-151) / 20

x = (3 +/- i*sqrt(151) / 20

if there's a "-" sign inside a square root, it will give you an imaginary number.

Example:

-sqrt(9) = -3

sqrt(-9) = 3i (first you will ignore the "- " sign, then square the number. After finding the square root, take that '-' sign and turn it to an "i")

So for sqrt(-151), 151 is not a perfect square, so you will get a decimal number. Leave it as it is:

sqrt(151). We can't forget about the "-". Turn the minus into a sign.

It will be i*sqrt(151)

Imaginary numbers can't be simplified, so this is the answer.

(3 +/- i*sqrt(151) / 20

Answer:

The area of the circular sector is approximately 39.269 square meters.

Step-by-step explanation:

A circular sector is a segment of a circle, whose area ([tex]A[/tex]), measured in square meters, is determined by this formula:

[tex]A = \frac{\theta}{2} \cdot r^{2}[/tex] (1)

Where:

[tex]\theta[/tex] - Central angle, measured in radians.

[tex]r[/tex] - Radius, measured in meters.

If we know that [tex]\theta = \frac{\pi}{4}[/tex] and [tex]r = 10\,m[/tex], then the area of the circular sector is:

[tex]A = \frac{\pi}{8} \cdot (10\,m)^{2}[/tex]

[tex]A \approx 39.269\,m^{2}[/tex]

The area of the circular sector is approximately 39.269 square meters.

39.269

6 5/12.

Step-by-step explanation:

4 2/3 + 1 3/4

= 4 + 1 + 2/3 + 3/4

= 5 + 8/12 + 9/12

= 5 + 17/12

= 5 + 1 5/12

= 6 5/12.

The correct answer for fraction equal to 0.57 is  [tex]\dfrac{19}{33}[/tex] and  [tex]\dfrac{26}{45}[/tex]. The correct 0ptions are C and B.

What is fraction?

A fraction is a numerical value that has both numerator and denominator.

Given Number:

A)

[tex]\dfrac{19}{30} = 0.63[/tex]

[tex]0.63[/tex] ≠ [tex]0.57[/tex]

B)

[tex]\dfrac{19}{33} = 0.5757[/tex]

[tex]0.57 = 0.57[/tex]

C)

[tex]\dfrac{26}{45} = 0.5777[/tex]

[tex]0.57 = 0.57[/tex]

D)

[tex]\dfrac{52}{99} = 0.52[/tex]

[tex]0.57[/tex] ≠ [tex]0.52[/tex]

The correct  fractions are [tex]\dfrac{19}{33}[/tex] and [tex]\dfrac{26}{45}[/tex] .The correct  options are C and B.

If you get it right/wrong, do let me know

Answer: 87.9

Step-by-step explanation:

Since the formula is 2 x pi x radius x height, we plug the equation in.

If you use “3.14” for pi, it’s 2 x 3.14 x 7 x 2 = 87.9 (rounded to the nearest tenth)

2 x pi x 7 x 2 = 87.96 (88 rounded to the tenth)

there is no any x

Step-by-step explanation:

but if you want to say -42x-3= -11

-42x-3+3= -11+3

-42x=8

-42x/-42=8/-42

x= -8/42

= -4/21

or if you want to say -42-3x= -11

-42+42-3x= -11+42

-3x= 31

-3x/-3=31/-3

x = -31/3

Answer: See explanation

Step-by-step explanation:

I think your question isn't well written and that 234 was meant to be 2.34 and 112 was meant to be 1.12

Let the amount spent on tomatoes be x.

The information given in the question can then be used to form an equation as thus:

Apples + Peaches + Tomatoes = $9.63

(2.34 × $1.32) + (1.12 × $1.20) + x = $9.63

$3.0888 + $1.344 + x = $9.63

x = $9.63 - ($3.0888 + $1.344)

x = $9.63 - $4.4328

x = $5.1972

The amount spent on tomatoes will be $5.1972

Answer:

The answer is 4.2 I did this question already

Step-by-step explanation: You multiply 2 3/4 and 1.32 and then add that to the product of the 1 1/2 peaches for 1.20 per pound, then subtract the answer from 9.63 to get the solution for x.
