Answer and work down below. Let me know if you have questions
Which scenario is modeled by the equation (x) (0.6) = 86 dollars and 46 cents? A picnic table is on sale for 60 percent off. The sale price of the picnic table is x, $144.10. A picnic table is on sale for 40 percent off. The sale price of the picnic table is x, $144.10 A picnic table is on sale for 60 percent off. The original price of the picnic table is x, $144.10. A picnic table is on sale for 40 percent off. The original price of the picnic table is x, $144.10
The equation of scenario is the right response is that the picnic table is worth $144.
What do equations mean in math?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
What exactly is a ratio?
A percentage is a component of a total amount, and the three-step rule is used to relate the measurements.
Using the value provided,
0.6x = 86.46
The price of a picnic table has been reduced by 40%. The picnic table cost x, or $144.10, upon launch.
When a product has a 40% discount applied,
100 - 40% = 60% of the original price x is paid;
as a result,
the price is expressed as: 0.6x.
The formula for this issue is
0.6x = 86.46
x = 86.46/0.6
x = 144.1.
Here, choice D is the best one.

complementary angles
If G= (6x-15)° and H= (3x+6)° find the x value and H
Answer:
x = 11 and H = 39°
Step-by-step explanation:
Complementary angles add up to 90 degrees, so angles G and H will add up to 90 degrees.
Create an equation by adding the expressions together and setting it equal to 90.
(6x - 15) + (3x + 6) = 90
Solve for x by adding like terms first:
9x - 9 = 90
Isolate x and solve:
9x = 99
x = 11
Then, find H by plugging in 11 as x into the expression:
3x + 6
3(11) + 6
33 + 6
= 39
So, x = 11 and H = 39°
The value of x is 11 and the value of H is 39.
Given,
G= (6x-15)°
H= (3x+6)° are complementary angles.
We need to find the value of x and H
What are complementary angles?
If the sum of two angles is 90 degrees the angles are called complementary angles.
We have,
G= (6x-15)°
H= (3x+6)° are complementary angles.
We can write it as,
(6x-15)° + (3x+6)° = 90°
6x - 15 + 3x + 6 = 90
9x - 9 = 90
9x = 90 + 9
9x = 99
x = 99/9
x = 11
Find the value of x and H.
x = 11.
H = 3x + 6
= 3 x 11 + 6
= 33 + 6
= 39
H = 39
Thus the value of x is 11 and the value of H is 39.

-21, -51, -81, -111, -141
Answer:
aₙ = - 30n + 9
Step-by-step explanation:
You can tell this is an arithmetic sequence, as there is a difference of 30 between each value. Therefore the equation we will use here is aₙ = a₁ + (n - 1)d.
aₙ = a₁ + (n - 1)d
= - 21 + (n - 1) * - 30
= - 21 - 30n + 30
= - 30n + 9
Your solution would be option d. aₙ = - 30n + 9

Step-by-step explanation:
Answer: Choice C) [tex]-6 \le x \le 2[/tex]
The domain is the set of possible x values or allowed inputs. The left-most point has x = -6 as the smallest allowed x value, while the right-most point has x = 2 as the largest allowed x value.
The domain is the set of numbers between -6 and 2, including both endpoints. So we write [tex]-6 \le x \le 2[/tex]
If you want the domain written in interval notation, then you would have [-6, 2]. The square brackets tell the reader "include the endpoint".

-9x - 33 + 17 - 19x simplify
Answer:
-28x -16 is the simplified answer.
Step-by-step explanation:
You have to move your constants towards your constants. So -9x and -19x are constants because their variable is the same. SO -9x plus -19x is -28x. And -33 and 17 are constant because they have the same variable so -33 plus 17 is -16. You can recheck my math to make sure.
Hello! :)
First, we will simplify
−9x + − 33 + 17 + −19x
Combine like terms
-9x + -33 + 17 + -19x
(-9x + -19x) + (-33 + 17)
-28x + -16

Given:
Consider the file sizes (in megabytes) for 18 randomly selected files on Gabriel's mp3 player are shown in the below figure.
To find:
The outliers in the distribution.
Solution:
We have, the given data set
2.4, 2.7, 1.6 , 1.3 , 6.2, 1.3, 5.6, 1.1, 2.2, 1.9, 2.1, 4.4, 4.7, 3.0, 1.9, 2.5, 7.5, 5.0
Arrange the data in ascending order.
1.1, 1.3, 1.3, 1.6, 1.9, 1.9, 2.1, 2.2, 2.4, 2.5, 2.7, 3.0, 4.4, 4.7, 5.0, 5.6, 6.2, 7.5,
Divide the data in 4 equal parts.
(1.1, 1.3, 1.3, 1.6), 1.9, (1.9, 2.1, 2.2, 2.4),( 2.5, 2.7, 3.0, 4.4), 4.7, (5.0,5.6, 6.2, 7.5)
It is clear that,
[tex]Q_1=1.9[/tex]
[tex]Q_3=4.7[/tex]
[tex]IQR=Q_3-Q_1[/tex]
[tex]IQR=4.7-1.9[/tex]
[tex]IQR=2.8[/tex]
Now,
[tex]Interval=[Q_1-1.5IQR,Q_3+1.5IQR][/tex]
[tex]Interval=[1.9-1.5(2.8),4.7+1.5(2.8)][/tex]
[tex]Interval=[-2.3,8.9][/tex]
All the data values lies in the interval [-2.3,8.9]. Therefore, the given data set have no outliers.
Calculate the mass of a liquid with a density of .7892 g/mL and a volume of 121.0 mL.
Answer:
95.49 g
Step-by-step explanation:
D = m/v
Looking for mass so isolate m to form equation format
D × V = m
Plug in numbers
.7892g/mL × 121.0 mL = 95.4932 g
Only g and not g/mL because the mL cancels each other out. It's easier to see if you rewrite it on paper.
Round to sig figs
Both original numbers hold 4 sig figs
