Answer:
h = 4.5
Step-by-step explanation:
16.5 + 2.75h = 9h + 7.5 − 4.25h
Combine like terms on the right side.
16.5 + 2.75h = 4.75h + 7.5
Subtract 4.75 h from both sides.
16.5 - 2h = 7.5
Subtract 16.5 from both sides.
-2h = -9
Divide both sides by -2.
h = 4.5
Answer:
h = 1.2
Step-by-step explanation:
1.) Isolate the variable H. To isolate the variable H, you have to move numbers onto one side and variable onto another. I will show this process in the next steps:
2.) First, move the numbers onto one side. You will subtract 7.5 on both sides, ending up with 16.5 - 7.5 + 2.75h = 9h - 4.25h.
3.) Now, move the variable to one side. You will subtract 2.75h on both sides, and get 16.5 - 7.5 = 9h - 4.25h + 2.75h.
4.) Finally, Simplify. 16.5 - 7.5 = 9. 9h - 4.25h + 2.75h = 7.5h. Therefore, 7.5h = 9.
5.) If we divide both sides by 7.5, we get h = 9/7.5, which is 1.2. By this, h = 1.2

A town has a population of 17000 and grows at 3% every year. What will be the
population after 10 years, to the nearest whole number?
If the population grows 3% every year, then each year's population is 103% of the previous year's population. This gives us the exponential function:
[tex]f(x) = 17000 (1.03)^x[/tex]
17000 for the current population, 1.03 growth factor for the 103%, raised to the x power because we'll need 103% of 103% of 103% and so on until we multiply by 103% for the correct number of years.
[tex]f(10) = 17000(1.03)^{10} \approx 22846.578448850072648[/tex]
Following standard math rounding this would round to 22,847 people.
If you argue that last 0.57844 of a person really round up, you could argue that this is really 22,846 people.
A jewelry designer plans to make a triangular pendant out of gold wire. The wire costs $31.65 per centimeter. What is the possible range of costs for the wire?
The wire can cost more than $____ and less than $____
The wire used for the triangular pendant can have a cost more than 664.65 USD and less than 791.25 USD.
How to determine the possible lengths of the missing side
In this problem we find the case of a triangle, in which the length of two sides are known and we need to determine the range of costs associated to the set of all possible triangles. This can be derived by the geometric system described in the image attached below. The minimum and the maximum costs of the pendant:
θ = 0°
l = 10.5 cm - 2.5 cm
l = 8 cm
s = 10.5 cm + 8 cm + 2.5 cm
s = 21 cm
C = (31.65 USD / cm) · (21 cm)
C = 664.65 USD
θ = 180°
l = 10.5 cm + 2.5 cm
l = 13 cm
s = 10.5 cm + 2.5 cm + 12.5 cm
s = 25 cm
C = (31.65 USD / cm) · (25 cm)
C = 791.25 USD

The function f(x) is defined as f(x) = One-third(6)x. Which table of values could be used to graph g(x), a reflection of f(x) across the x-axis?
The table of values that could be used to graph g(x), a reflection of f(x) across the x-axis is table (c)
How to determine the table of values?From the question, we have the following equation that can be used in our computation:
f(x) = One-third(6)x
When this statement is represented as an equation, we have the following representation
f(x)= 1/3(6)ˣ
The transformation is given as
A reflection of f(x) across the x-axis
This means that
g(x) = -f(x)
So, we have
g(x) = -1/3(6)ˣ
What this means is that the values of f(x) are negated to get g(x)
The table that represents this is table (c)

Michael went shopping for a new video game because of a sale. The price on the tag was $46, but Michael paid $34.50 before tax. Find the percent discount.
The discount percentage offered on the new video game as of a sale is 75%.
Explain the term discount percentage?When a product is offered at a discount, the seller is reducing the product's price from what it was originally listed for. The percentage discount just on product is determined by the discount amount stated as a percentage of the initial price.For the stated question-
The listed price on the video game = $46.
price paid exclusive of tax = $34.50.
Let 'x' be the percentage discount of the listed price.
Then,
x% of 46 = 34.50
x = 34.50 x 100 / 46
x = 75%

Supplementary angles are angles that have a sum of 180 degrees. They are formed on a straight line.
Solving the QuestionLooking at the given diagram, we can notice how angle SUV and SUT are supplementary angles. We know this because they form the straight line, VT.
We are given angle SUT, which is 58 degrees.
Because angles SUV and SUT have a sum of 180 degrees, we can solve for angle SUV by subtracting 58 from 180:
180 - 58 = 122
Therefore, angle SUV is 122 degrees.
Answer122 degrees
Answer:
Angle SUV = 180 - 58

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 7 rows of the same length, he has 5 chairs left over. If he arranges the chairs in 5 rows of that same length, he has 17 left over. How many chairs does Liam have?
Answer: 47
Step-by-step explanation: Let's call the number of chairs Liam has x. We can set up the following equations to represent the problem:
7r = x - 5
5r = x - 17
Where r is the length of each row.
To solve for x, we can set the two equations equal to each other:
7r = x - 5
5r = x - 17
Then we can solve for x by combining like terms and solving for the value of x:
7r - 5r = x - 5 - x + 17
2r = 12
r = 6
We can substitute the value of r back into either of the original equations to solve for x:
7r = x - 5
7 * 6 = x - 5
x = 47
Therefore, Liam has 47 chairs.

The straight line that "just touches" the curve at a given point is referred to as the tangent line to a plane curve in geometry. It was defined by Leibniz as the path connecting two points on a curve that are infinitely close together.
Given:
Graph is a parabola tangent to the x-axis at (4,0) with y-intercept 6.
That is there are two points (4, 0) and (0, 6).
From these two points we have to find the slope of the line.

Now to use point slope form of the line.
[tex]y-y_1 = m(x-x_1)\\ y - 6 = -\frac{3}{2}(x-0)\\ y - 6 = -\frac{3}{2}x\\ y = -\frac{3}{2}x + 6[/tex]
