What is the solution to
-(6x+8)= 4(17 – x)?
Answer:
x=30
Step-by-step explanation:
Simplifying
6x + 8 = 4(x + 17)
Reorder the terms:
8 + 6x = 4(x + 17)
Reorder the terms:
8 + 6x = 4(17 + x)
8 + 6x = (17 * 4 + x * 4)
8 + 6x = (68 + 4x)
Solving
8 + 6x = 68 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
8 + 6x + -4x = 68 + 4x + -4x
Combine like terms: 6x + -4x = 2x
8 + 2x = 68 + 4x + -4x
Combine like terms: 4x + -4x = 0
8 + 2x = 68 + 0
8 + 2x = 68
Add '-8' to each side of the equation.
8 + -8 + 2x = 68 + -8
Combine like terms: 8 + -8 = 0
0 + 2x = 68 + -8
2x = 68 + -8
Combine like terms: 68 + -8 = 60
2x = 60
Divide each side by '2'.
x = 30
Simplifying
x = 30

You’re playing a dice game with 5 fair d6s. You need to roll at least four number 6's to win the next round, what is the probability you win ?
The probability of winning is 0.00078395061 or approximately 0.078%.
There are five dice, and each dice has six sides.
There are a total of 6^5 possible outcomes.
This gives us 7776 possible outcomes.
We want to find the probability that we get at least four 6s in the next round.
The probability of getting exactly four 6s can be found by using the binomial distribution, which is given by the formula:
P(4) = (5 choose 4) * (1/6)^4 * (5/6)^1
P(4) = 5 * (1/6)^4 * (5/6)^1
P(4) = 0.00077160493
The probability of getting exactly five 6s can be found in a similar way:
P(5) = (5 choose 5) * (1/6)^5 * (5/6)^0
P(5) = 1 * (1/6)^5 * (5/6)^0
P(5) = 0.00001234568
The probability of getting at least four 6s is the sum of the probabilities of getting exactly four 6s and exactly five 6s.
P(at least 4) = P(4) + P(5)
P(at least 4) = 0.00077160493 + 0.00001234568
P(at least 4) = 0.00078395061
So, the probability of winning the next round by rolling at least four number 6's is 0.00078395061. This is equivalent to approximately 0.078%. Hence, the probability of winning is 0.00078395061 or approximately 0.078% which is calculated by using binomial distribution formula.

A rotation of 180°about the origin followed by a translation of one unit to the left.
A rotation of 180° about the origin followed by a translation of one unit to the right.
The amount consists of two steps: first, a reflection in the x-axis followed by a reflection in the y-axis, then a rotation of 180° about the origin, followed by a translation of one unit either to the left or to the right.
The transformation first consists of two reflections, one in the x-axis and one in the y-axis. This will create a mirror image of the original shape, flipping it across the x-axis and then the y-axis. The next step is a rotation of 180° about the origin. This will turn the shape around so that the reflection is facing the opposite direction. The last step is a translation of one unit either to the left or to the right. This will move the shape one unit in the specified direction, creating a new shape with the same orientation and size as the original, but shifted in space. This transformation will create a new shape that is a symmetrical mirror image of the original shape, with a different position in space.

The length of a rectangle i 2cm greater than the width of the rectangle. The perimeter of the rectangle i 24cm
The length of the rectangle is 7 cm and the width is 5 cm.
Perimeter of a rectangle:The whole distance covered by the rectangle's borders or its sides is known as its perimeter. As we know the rectangle will have 4 sides then the perimeter of the rectangle will be equal to the total of its four sides. And the unit will be in meters, centimeters, inches, feet, etc.
The formula for the Perimeter of the rectangle is given by
Perimeter = 2( Length + Width )Here we have
The length of a rectangle is 2cm greater than the width of the rectangle
And perimeter of the rectangle = 24 cm
Let x be the width of the rectangle
From the given data,
Length of the rectangle = (x + 2) cm
As we know Perimeter of rectangle = 2(Length+width)
=> Perimeter of rectangle = 2(x+2 + x) = 2(2x +2)
From the given data,
Perimeter of rectangle = 24cm
=> 2(2x +2) = 24 cm
=> (2x +2) = 12 [ Divided by 2 into both sides ]
=> 2x = 12 - 2
=> 2x = 10
=> x = 5 [ divided by 2 into both sides ]
Length of rectangle, (x+2) = 5 + 2 = 7 cm
Therefore,
The length of the rectangle is 7 cm and the width is 5 cm.

Find the area of the shaded part of circle Y.
Answer:
201.45 cm²
Step-by-step explanation:
The whole circle has an area of π(9)² cm², or 81π cm². The shaded part represents all of the circle except for the chunk swept out by sector XZ.
Sector XZ sweeps out 75°, which represents 75/360 of the whole circle, or, simplified, 15/72. That means the shaded area must represent the other 57/72. To find the area then, we can just multiply that fraction by 81π:
\(81\pi\cdot\frac{57}{72}=9\pi\cdot\frac{57}{8}\)
Using π ≈ 3.14 and crunching the numbers out gives us a result of approximately 201.45 cm².

An auto-parts store offers a fuel additive that claims to increase a vehicle’s gas mileage. The additive is poured into a vehicle’s gasoline tank after the tank is filled. To measure the claim, two methods to collect data are proposed.
Method A: 20 similar police cars owned by a city are selected. After the cars are filled with a fresh tank of gasoline, researchers randomly select 10 of the cars to receive the additive, while the other 10 do not receive the additive. The gas mileage for each car is recorded in miles per gallon.
Method B: 20 customers at an auto-parts store receive free coupons for the additive and are asked to use it with their next fresh tank of gasoline. The customers then report their gas mileage with the fuel additive.
Which method describes an experiment?
Method B is an experiment because every car receives the additive.
Method A is an experiment because the additive is used with a new tank of gasoline.
Both methods are experiments because the additive is used in a new tank of gas in both methods.
Method A is an experiment because random assignment determines which cars receive the additive and which cars do not.
Answer:
Method A is the answer
Answer:
Step-by-step explanation:
Method A is an experiment because random assignment determines which cars receive the additive and which cars do not. Method B is not an experiment because there is no control group and participants are self-selecting, which can introduce bias and confounding variables that may affect the results.

During batting practice, two pop flies are hit from the same location, 2 s apart. the paths are modeled by the equations h = -16t2 + 56t and h = -16t2 + 156t - 248, where t is the time that has passed since the first ball was hit. explain how to find the height at which the balls meet. then find the height to the nearest tenth. to find the time at which both balls are at the same height, set the equations equal to each other then solve for t. the balls meet at a height of ft.
The time at which both balls are at the same height is t = 2.48 seconds and the balls meet at a height of approximately 125.44 feet.
To find the height at which the balls meet, we need to set the two equations equal to each other:
-16t^2 + 56t = -16t^2 + 156t - 248
By simplifying the equation, we can cancel out the -16t^2 terms and rearrange it to:
100t - 248 = 0
Next, we solve for t by isolating the variable:
100t = 248
t = 248/100
t = 2.48 seconds
Now, we substitute this value of t into one of the original equations to find the height at which the balls meet. Let's use the first equation:
h = -16(2.48)^2 + 56(2.48)
h ≈ 125.44 feet
So, the balls meet at a height of approximately 125.44 feet.

The statement says that you've triggered the Penalty APR so that it has now increased to 28.99%. What action triggered this? You failed to pay the minimum payment by the due date.
You failed to make the minimum payment by the due date. This is an action that can result in a message that "you've triggered the Penalty APR so that it has now climbed to 28.99%."
A charge APR is a charge that can be applied if you don't pay your bills on time. It may be set up so that future transactions may be subject to a penalty APR that is higher than the card's standard rate.
If the minimum payment was not made by the due date, Penalty APR would be applied.
But if the card also has a penalty APR and you trigger it, you will likely lose that promotional offer. Federal consumer protections that limit penalty APRs don't apply to small-business credit cards.

Select the true statement. Dilations of an angle must be congruent to the original angle. Dilations of a triangle must be congruent to the original triangle Dilations of a segment must be congruent to the original segment. Dilations of a circle must be congruent to the original circle.
Answer:
The true statements is;
Dilations of an angle must be congruent to the original angle
Step-by-step explanation:
Given that an angle is formed by the intersection of two rays, and that the ratio of the sides of a figure, before and after a dilation are the same, for an angle in a triangle we have, by sine rule;
a/(sin(α)) = b/(sin(β)) = c/(sin(γ))
Rearranging, gives;
a/b = (sin(α))/(sin(β))
Whereby for the dilation, we have;
a'/b' = (sin(α'))/(sin(β'))
We have;
a/b = a'/b'
∴ (sin(α))/(sin(β)) = (sin(α'))/(sin(β'))
Similarly, we have;
(sin(β))/(sin(γ)) = (sin(β'))/(sin(γ'))
(sin(α))/(sin(γ)) = (sin(α'))/(sin(γ'))
Given that α, β, and γ, are less than 180°, we have
α = α'
∴ α ≅ α' by definition of congruency
β = β'
β ≅ β' by definition of congruency
γ = γ'
γ ≅ γ' by definition of congruency
Therefore; dilations of an angle must be congruent to original angle
