Answer: x > - 9 or x < - 26
Step-by-step explanation:
Ok, so modulus means that 0.2x + 3.5 is either greater than 1.7, or less than -1.7. Putting that in equation, we get,
0.2x + 3.5 > 1.7 or 0.2x + 3.5 < -1.7
0.2x > -1.8 or 0.2x < -5.2
x > -9 or x < -26
There u go.

Zell invested $80,000 in two different types of stocks. The first type earned 9% and the second type earned 12%. If the profit on the 12% stocks was $150 more than the profit on the 9% stocks, how much did Zell invest in the 9% stock?
Answers
Zell invested $80,000 in two different types of stocks. Solving for x gives us the amount invested in the 9% stock:
x = $45000
What is stock?Generally, Let x be the amount invested in the 9% stock.
Then (80,000 - x) is the amount invested in the 12% stock.
The profit on the 9% stock is 0.09 * x and the profit on the 12% stock is
0.12 * (80,000 - x).
We know that the profit on the 12% stock is $150 more than the profit on the 9% stock.
So we can set up the following equation:
0.12 * (80,000 - x)
= 0.09 * x + 150
x=45000
Therefore, Zell invested $80,000 in two different types of stocks. the amount invested in the 9% stock is $45000

a person is standing 10 feet away from a street light that is 22 feet tall. how long is his shadow if he is 6 feet tall? enter the exact value of the answer.
Answers
Length of the person's shadow is 3.75 feet.
Consider triangle as shown, segment DE represent the person standing, A represent the location of light, 22 feet away from ground, BC. The shadow's length would be the length of CE.
In triangle ABC and triangle DEC, ∠C is common, and ∠CBA = ∠CED = 90°. So by AA criterion, the triangles are similar. Thus
BC/ CE = AB/ DE
(BE + CE)/CE = AB/ DE
1 + BE/CE = AB/ DE
1 + 10/CE = 22/6
10/CE = 16/6 = 8/3
CE = (10 × 3)/8

Table B represents a function because there is only one input for each

Answers
Table A represents a function, but Table B does not represent a function.
What is a function?
A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.
A function or mapping is described as a collection of pairs of x and y that are ordered such that given different values of x, there will also be different values of y, or vice versa. For instance, the function x=y+2 yields a different x for every different value of y, while yielding the same x value for every single different value of y. We obtain two distinct x for two distinct ys, thus we can refer to this as a function at that point.
As, each element of X is associated with unique element of Y, so this is a function.
Table A

As, each element of X is associated with a unique element of Y, so this is a function.

What does sin t mean in math?The functions sin and cosine, sometimes known as sin() and cos(), show how a right triangle is shaped.
The ratio of the opposite side to the hypotenuse is called sin(), and the ratio of the adjacent side to the hypotenuse is called cos(), when viewed from a vertex with angle.
So, the Pythagorean identity-based formula for sin is sin²x = 1 - cos²x.
Hypotenuse²=base²+perp²
(8)²=(7)²+(perp)²
64=49+(perp)²
64/49=perp²
1.306=perp²
Now taking square root on both sides
Perp=√1.306
Perp=1.142

In the given question, a lawn sprinkler located at the corner of a yard rotates through 80 degrees and sprays water of 20 ft.
We have to find the length of the arc of the sector watered.
From the given question,
r = 20 ft, θ = 80 degree
A sector is referred to as a component of a circle made up of the circle's arc and its two radii. It is a section of the circle made up of the arc's circumference and the radii of the circle at its ends.
The formula for the length of the arc of the sector watered is

Now putting the value
L = [tex]\frac{80^{o}}{360^{o}}\times 2\times\pi \times20[/tex]

after a gymnastics meet, each gymnast shook hands once with every gymnast on every team (except herself). afterwards, a coach came down and only shook hands with each gymnast from her own team. there were a total of $281$ handshakes. what is the fewest number of handshakes the coach could have participated in?
Answers
So, the coach could have participated in at least 14 handshakes.
The total number of handshakes is the sum of the handshakes between gymnasts from different teams and the handshakes between gymnasts from the same team and the coach.
The coach shakes hands with each gymnast from her own team, so the number of handshakes between the coach and gymnasts is equal to the number of gymnasts on the team.
Let's assume the number of gymnasts on a team is x. And the number of teams is y. So the number of handshakes between gymnasts from different teams is x*(x-1)*y/2.
Given the total number of handshakes is 281, we know that:
x*(x-1)*y/2 + x = 281
In order to get the minimum number of handshakes the coach could have participated in, we can assume the maximum number of gymnasts on a team, which is x = 14.
So the equation becomes:
1413y/2 + 14 = 281
So we can find the value of y by solving this equation:
y = (281-14)/(13/2) = 17
Therefore, with x = 14 and y = 17, the minimum number of handshakes the coach could have participated in is 14, which is the number of gymnasts on the team.
So the coach could have participated in at least 14 handshakes.

(
Answers
The required number of containers are two.
How to solve the problem to number of container?105 minutes per process cycle.
We must first determine the utilization rate of the process in order to determine the number of containers required for the parts. Usage rate is the typical unit utilised each hour.
The scenario specifies that the procedure uses 88 components every hour.
The net cycle time per part per hour is determined as follows: (99/60) x 105 = 173.25
0.31 is the efficiency factor.
We can determine the total number of things Kanban can maintain using the information provided:
= 173.25/(1 - 0.31)
= 119.54
We may calculate the total number of containers required by dividing the container capacity by the entire number of parts after we know how many total pieces will be stored.
Each container can hold 8 dozens, or 96 pieces.
= 119.54

The roots of the equation x^2+bx+c=0 are -4 and 2. Find b
Answers
Answer:
The value of b in the equation x^2+bx+c=0 can be found using the quadratic formula. The quadratic formula states that the roots of the equation are given by:
x = (-b ± √(b^2 - 4ac))/2a
Where a = 1, since the coefficient of x^2 is 1, b = b and c = c.
Step-by-step explanation:
Given that the roots of the equation are -4 and 2, we can substitute these values for x into the equation and solve for b.
For the first root of -4, we get:
1x^2 + bx + c = (1)(-4)^2 + b(-4) + c = 0
This simplifies to:
16 - 4b + c = 0
For the second root of 2, we get:
1x^2 + bx + c = (1)(2)^2 + b(2) + c = 0
This simplifies to:
4 + 2b + c = 0
Now we have two equations with two unknowns, we can use the substitution method to find the value of b.
By equating the two equation we get:
16 - 4b + c = 4 + 2b + c
We can simplify it as:
12 - 2b = 0
therefore b = 6
In summary, the value of b in the equation x^2+bx+c=0 is 6 when the roots of the equation are -4 and 2.

Step-by-step explanation:
x = (asin(B)) / (sin(B))
x = (21sin(61∘)) / (sin(71∘))
x = 19.425 cm
Jessica is measuring two line segments. The first line segment is 30 cm long while the second line segment is 500 mm long. How long are the two line segments together?A. 80 cmB. 25 cmC. 47 cmD. 49 cm
Answers
The length of the two line segments together is 80 cm
Step 1: Convert 500mm into cm.
We know that the value of 1mm is equal to 0.1 cm.
Then, 500mm will be 500mm*0.1 = 50 cm.
Therefore, the second line segment is 50 cm long.
Step 2: Calculate total length.
Let the first line segment be L1= 30 cm long and the second line segment be L2= 50 cm long.
Now, the total length is
L = L1 + L2
Substitute the values L1= 30 cm and L2= 50 cm in L = L1 + L2.
Hence, the length of the two line segments together is 80 cm
