solve......... 6y + x = 8

Answer:

x = ± [tex]\sqrt{3}[/tex]

Step-by-step explanation:

Given

3x² - 9 = 0 ( add 9 to both sides )

3x² = 9 ( divide both sides by 3 )

x² = 3 ( take the square root of both sides )

x = ± [tex]\sqrt{3}[/tex]

ANSWER

84%,0.82,¾,⅓

EXPLANATION

Convert everything to decimals.

[tex] \frac{3}{4} = 0.75[/tex]

[tex] 84\% = 0.84[/tex]

[tex] \frac{1}{3} = 0.333....[/tex]

The last one is already in decimals.

[tex]0.82[/tex]

We can now see clearly, that

[tex]0.84 \: > \: 0.82 \: > \: 0.75 \: > \: 0.3333...[/tex]

This implies that,

[tex]84\% \: > \: 0.82 \: > \: \frac{3}{4} \: > \: \frac{1}{3} [/tex]

Hence from highest to least, we have

84%,0.82,¾,⅓

Answer:

179.78

Step-by-step explanation:

Let's count how much Abe has exactly:

32 one-dollar bills: $32

4 five-dollar bills: $20

32 quarters: $8

25 dimes : $2.50

82 pennies :  $0.82

First check: $43.56

Second check: $122.90

Total = $229.78

And he wants a $50 bill... so he'll deposit $179.78 ($229.78 - $50).

Final answer:

Abe Cassidy will deposit $179.78 into his savings account.

Explanation:

Let's calculate how much Abe Cassidy will deposit into his savings account, considering he wants to receive a $50.00 bill in cash. To do this, we need to add up all the various types of money he has and then subtract the $50 he wishes to keep in cash.

Adding all these amounts gives us a total of $229.78 before removing the $50 he wants in cash.

To find the amount he will deposit, we subtract the $50 from the total amount:

$229.78 - $50 = $179.78

Hence, Abe Cassidy will deposit $179.78 into his savings account.

Answer:

x=1

Step-by-step explanation:

We can find the slope given two points by

m = (y2-y1)/(x2-x1)

2 = (6--2)/(x--3)

2 = (6+2)/(x+3)

2 = 8/(x+3)

Multiply each side by x+3

2(x+3) = 8/(x+3) * (x+3)

2(x+3) = 8

Divide each side by 2

2/2 (x+3) = 8/2

x+3 = 4

Subtract 3 from each side

x+3-3=4-3

x =1

Answer:

V = x³ + 10x² cm³

Step-by-step explanation:

The volume (V) of the triangular prism is calculated using the formula

V = area of triangular face × length

Area of triangular face = [tex]\frac{1}{2}[/tex] bh ( b is base and h is height )

here b = 2x and h = x, thus

A = [tex]\frac{1}{2}[/tex] × 2x × x = [tex]\frac{1}{2}[/tex] × 2x² = x²

length = x + 10, hence

V = x²(x + 10) = x³ + 10x²

Answer:

ρ = 35% or 0.35

ρ with ^ = [tex]\frac{23}{50}=0.46[/tex] or equivalently 46%

Step-by-step explanation:

ρ represents the population proportion of the bus riders, with a monthly pass, who are students.

The population proportion is simply the percentage of the entire population with a particular characteristic. We have been informed that in a city, 35% of the bus riders with a monthly pass are students. This means that 35% of the whole population of bus riders with a monthly pass are students. Therefore, our ρ is simply 35% or 0.35.

ρ with ^ represents the sample proportion of the bus riders, with a monthly pass, who are students. This is a statistic or an estimator as it is normally used to estimate the value of ρ, the population proportion. It is calculated using the formula;

ρ with ^ = [tex]\frac{x}{n}[/tex]

where n represents the size of the sample and x the number of individuals in the sample with a certain desired characteristic. We have been informed that;

in a random sample of 50 bus riders with monthly passes, 23 are students.

Using the above formula and the values given we have;

ρ with ^ = [tex]\frac{23}{50}=0.46[/tex] or equivalently 46%

Answer: The correct answer is: ρ=0.35, ρˆ=0.46

Answer:

x=0

Step-by-step explanation:

x^2+6x-27=-27

x^2+6x=0

x(x+6)

x=0, x=-6

The solution to (x - 3)(x + 9) = -27 is x=6, the correct option is D.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

We are given that;

(x - 3)(x + 9) = -27

Now,

If we plug in x = 6 into the equation,

we get: (6 - 3)(6 + 9) = -27.

Simplifying, we get: (3)(15) = -27.

Multiplying, we get: 45 = -27. This is true, so x = 6 is a solution.

The other values of x do not satisfy the equation.

For example, if we plug in x = -9, we get: (-9 - 3)(-9 + 9) = -27. Simplifying, we get: (-12)(0) = -27.

Multiplying, we get: 0 = -27. This is false, so x = -9 is not a solution

Therefore, by quadratic equations the answer will be x = 6.

If she uses a $100 bill to pay for the pumpkins, then the amount of change that she receives will be $ 32.5.

It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.

The line plot shows the weights of pumpkins available at a farm stand. The pumpkins cost $0.30 per pound. A baker purchases all of the pumpkins to make pies.

Then the weight of all the pumpkins will be

→ 6 x 3 + 8 x 5 + 9 + 10 x 7 + 12 x 4 + 13 x 2 + 14

→ 225 pounds

Then the amount of money of 225 pounds will be

→ 225 x 0.3

→ $ 67.5

If she uses a $100 bill to pay for the pumpkins, then the amount of change that she receives will be

→ $ 100 - $67.5

Answer: B

Step-by-step explanation: The Answer is B. 30 Sides.

The number of sides of the regular polygon each interior angle measuring 168° is 30. Thus, the correct option is B.

A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.

The measure of interior angles of a regular polygon is given by the formula,

[tex]\text{Measure of an interior angle} = \dfrac{(n-2) \times 180^o}{n}[/tex]

where n is the number of sides in the polygon.

Since it is given that measure of an interior angle of the polygon is 168°. Therefore, the number of sides will be,

[tex]168 = \dfrac{(n-2) \times 180^o}{n}[/tex]

168n = 180n - 360

180n - 168n = 360

12n  = 360

n = 30

Hence, The number of sides of the regular polygon each interior angle measuring 168° is 30.

Answer:  [tex](f/g)(x)=\frac{2x}{x+5}[/tex]

Step-by-step explanation:

Given the function f(x):

[tex]f(x)=4x^2+6x[/tex]

And the function g(x):

[tex]g(x)=2x^2+13x+15[/tex]

To find [tex](f/g)(x)[/tex] you need to divide the function f(x) by the function g(x).

Therefore, knowing this, you get:

[tex](f/g)(x)=\frac{4x^2+6x}{2x^2+13x+15}[/tex]

You can simplify the numerator by factoring out 2x:

[tex](f/g)(x)=\frac{2x(2x+3)}{2x^2+13x+15}[/tex]

 You have to simplify the denominator:

 Rewrite the term 13x as a sum of two terms whose product be 30:  

[tex](f/g)(x)=\frac{2x(2x+3)}{2x^2+(10+ 3)x+15}[/tex]

Apply Distributive property:

[tex](f/g)(x)=\frac{2x(2x+3)}{2x^2+10x+ 3x+15}[/tex]

Make two groups of two terms:

[tex](f/g)(x)=\frac{2x(2x+3)}{(2x^2+10x)+ (3x+15)}[/tex]

Factor out 2x from the first group and 3 from the second group:

[tex](f/g)(x)=\frac{2x(2x+3)}{(2x(x+5))+ 3(x+5)}[/tex]

Factor out (x+5):

[tex](f/g)(x)=\frac{2x(2x+3)}{(2x+3)(x+5)}[/tex]

Simplifying, you get:

[tex](f/g)(x)=\frac{2x}{x+5}[/tex]

ANSWER

[tex]( \frac{f}{g} )(x) = \frac{2x }{x + 5}[/tex]

where

[tex]x \ne - \frac{3}{2} \: or \: x = - 5[/tex]

EXPLANATION

The given functions are:

[tex]f(x) = 4 {x}^{2} + 6x[/tex]

and

[tex]g(x) =2 {x}^{2} + 13x + 15[/tex]

We want to find ,

[tex]( \frac{f}{g} )(x) = \frac{f(x)}{g(x)} [/tex]

[tex]( \frac{f}{g} )(x) = \frac{4 {x}^{2} + 6x }{2 {x}^{2} + 13x + 15} [/tex]

[tex]( \frac{f}{g} )(x) = \frac{2x(2x + 3) }{2{x}^{2} + 10x +3x + 15} [/tex]

[tex]( \frac{f}{g} )(x) = \frac{2x(2x + 3) }{2{x}(x + 5) +3(x + 5)} [/tex]

[tex]( \frac{f}{g} )(x) = \frac{2x(2x + 3) }{(2x + 3)(x + 5)} [/tex]

Answer:

343.7 ft

Step-by-step explanation:

The wire is anchored 190 -13 = 177 ft from the ground. That distance is opposite the given angle (31°). The measure you want is the hypotenuse of the triangle with that side and angle measures.

The mnemonic SOH CAH TOA reminds you that the relation between the opposite side, hypotenuse, and angle is ...

Sin(angle) = Opposite/Hypotenuse

Filling in the given information, you have ...

sin(31°) = (177 ft)/hypotenuse

Solving for hypotenuse gives

hypotenuse = (177 ft)/sin(31°) ≈ 343.7 ft

The length of the guy wire should be 343.7 ft.

To find the length of the guy wire attached 13 feet from the top of a 190-foot tall tower at an angle of 31° with the ground, we can use the sine function and trigonometry. The length of the guy wire is approximately 380.8 feet.

To find the length of the guy wire, we can use trigonometry. The guy wire, the height of the tower, and the distance from the top of the tower to the attachment point form a right triangle. We can use the sine function to find the length of the guy wire: sin(31) = height of the tower / length of the guy wire. Rearranging the equation gives us length of the guy wire = height of the tower / sin(31). Plugging in the values, we get length of the guy wire ≈ 190 / sin(31) ≈ 380.8 feet. Therefore, the guy wire should be approximately 380.8 feet long.
