The angle sum property of a triangle states that:
Sum of three angles of a triangle is 180 degrees.
Now we are given a right angled triangle here.
The question can be described as shows in figure.
Here ABC is a triangle right angles at B.
The other angle is 58 degrees.
Using angle sum property:
∠A + ∠B +∠C =180
let ∠A = 58° and ∠B =90°
So we have ,
58° + 90° +∠C =180
148°+∠C=180°
∠C = 32°
Answer : Angle C is 32 degrees.
Option A is correct choice

A nontoxic furniture polish can be made by combining vinegar and olive oil. the amount of oil should be five times the amount of vinegar. how much of each ingredient is needed in order to make 39 oz of furniture polish?
Answers
Let V be the amount of vinegar and L be the amount of oil.
Since the amount of oil is 5 times the amount of vinegar, L = 5V. We know that together they form 39 oz; therefore
V + 5V = 39
6V = 39
Divide both sides by 6:
6V/6 = 39/6
V = 6.5
L = 5V = 5(6.5) = 32.5
Final answer:
To make 39 oz of non-toxic furniture polish with the ratio of olive oil being five times the amount of vinegar, 6.5 oz of vinegar and 32.5 oz of olive oil are needed.
Explanation:
We know the oil to vinegar ratio is 5:1.
Let x be the amount of vinegar: We can use any variable to represent the unknown amount.
Set up the equation: Since the total volume is 39 oz and the ratio is 5:1, we have the equation: x (vinegar) + 5x (olive oil) = 39 oz.
Combine like terms: 6x = 39 oz.
Solve for x (vinegar): x = 39 oz / 6 = 6.50 oz.
Calculate the olive oil amount: Olive oil = 5 × vinegar = 5 × 6.50 oz = 32.50 oz.
Therefore, you'll need 6.50 oz of vinegar and 32.50 oz of olive oil to make 39 oz of furniture polish.
Remember to always test the polish on a small inconspicuous area of the furniture before applying it to the entire surface. And, for best results, use a clean, soft cloth to apply the polish and buff it to a shine.

The doubly-shaded area is the solution set. The dashed line is not included.
Answer:
Graph B is the answer.
Step-by-step explanation:
We know that both functions are inequalities, however,
The second one (red on the graph) has 'less or equal sign, ≤' meaning that, the line of the function is included as shown on graph B with a continuous line.
The first one has a 'greater than, >' meaning that the line of the function is not included, therefore the line is a dotted line, as shown on graph B.
The shaded area must be between the two inequalities because that where the X's can be met.
Therefore, the answer is graph B.

To find the missing side, you have to write a proportion because the sides are proportional.
When an angle is bisected like this, you can write:
28/x = 12/(30 - x)
Cross multiplying will give you:
12x = 840 - 28x
40x = 840
x = 21
You could plug the 21 back in and you will see that the sides are proportional.

The height h, in feet, of a projectile t seconds after launch is modeled by the equation h = 32t – 16t2. how long after launch does the projectile return to the ground? 2 seconds4 seconds14 seconds16 seconds
Answers
v = 32 - 32t
at Max hight speed is 0m/s
therefore
0 = 32 - 32t
t = 32/32 = 1 s
so it goes up to Max hieght in 1 s
and it takes another 1s to come back
thus time after launch to return to ground is 2s!
Answer:
The correct option is A. 2 seconds
Step-by-step explanation:
The height h, in feet, of a projectile t seconds after launch is modeled by the equation h = 32·t – 16·t²
Now, we need too find the time after which the fired projectile touches the ground.
So, The fired projectile when touches the ground, The height of the projectile will become 0
⇒ Find the required time t when h = 0
⇒ 0 = 32·t - 16·t²
⇒ 0 = t × (32 - 16·t)
⇒ t = 0 or 32 - 16t = 0
⇒ 16t = 32
⇒ t = 2
So, t = 0 or t = 2
t cannot be 0 because initially the projectile is in the air as it has been already fired
⇒ t = 2 seconds
Therefore, The correct option is A. 2 seconds

Let f(x)=4x^2+x+1 and g(x)=x^2-2. Find g(f(x)). Show each step of your work.
Answers
Today we are dealing with composite functions. I am going to introduce you to a new way of thinking about any function and this will help you in your understanding of composite functions.
So I want you to think of a function like a machine. Let's take a function and call it the f machine. If you take the input value 'x' and insert it into the f machine, you get f(x) as an output.
Now, for composite functions, the process is very similar BUT slightly more complicated. If we wanted to find g(f(x)), we would plug in 'x' to the f machine to get the output f(x). After that, we would plug the output into the g machine to get g(f(x)).
Let's try an example. Let's say f(x)=4x²+x+1 and g(x)=x²-2 and we want to find g(f(x)).
Well it looks like they already gave us the output for plugging x into the the f machine. The output is 4x²+x+1. Now we have to plug this into the g machine. Since the output that plugging x into the g machine is x²+2, and we want to find g(4x²+x+1), plug in 4x²+x+1 for x in the g machine. (This also means that g(4x²+x+1)=g(f(x)).)
Look...
g(4x²+x+1)=(4x²+x+1)²+2
which means...
g(f(x))=(4x²+x+1)²+2
Now simplify this...
(4x²+x+1)(4x²+x+1)+2
16x⁴+4x³+4x²+4x³+x²+x+4x²+x+1
16x⁴+8x³+9x²+2x+1

This is a little confusing. But it’s 10. If there’s 2 sides with the length of 4 and one with 10, then it’s not a closed triangle. With two sides lengths of 10 and one with 4, the triangle is able to be closed.

Explanation:

We want to find (f-g) (x), we can simply obtain the result by subtracting g (x) from f (x) as follows:
(f-g) (x) = f (x) - g (x)
(f-g) (x) = 3x + 1 - (x²-6)
(f-g) (x) = 3x + 1 - x² + 6

Matias and Hannah are responsible for the centerpieces on the buffet tables at the school dance.they have 6 dozen carnations,80 lilies,and 64 rosebuds. all the centerpieces must be identical.determine the greatest number of centerpieces Matias and Hannah can make if they use all the flowers.then describe the centerpiece

There are 2 ways you can find the gcf:

80-1,2,4,5,8,10,16,20,40,80
68-1,2,4,17, 34, 68
The greatest common factor is 4.
2. List prime factorization and match all prime numbers from all 3 lists.
72=2x2x2x3x3
80=2x2x2x2x5
68=2x2x17
2x2=4 flower arrangements
Each of the 4 center pieces will have 18 carnations, 20 lilies, and 17 rosebuds.
Matias and Hannah can make 8 identical centerpieces using all the flowers, with each centerpiece composed of 9 carnations, 10 lilies, and 8 rosebuds, arranged harmoniously.
Explanation:Matias and Hannah can make the greatest number of identical centerpieces by finding the largest number that can divide into the quantities of all three types of flowers without remainder. They have 6 dozen carnations (72 carnations), 80 lilies, and 64 rosebuds. The highest common factor that divides into 72, 80, and 64 is 8. This means they can make 8 centerpieces, with each centerpiece containing 9 carnations, 10 lilies, and 8 rosebuds.
Describing the centerpiece based on the description in the hypothetical art reference: The centerpiece would feature a balanced and harmonious arrangement of flowers with the carnations drawing the viewer's attention at the center. Similar to the composition in Chittenden's paintings, the various flower types, such as lilies and the delicate rosebuds, would be distributed to complement each other in the arrangement, creating an aesthetically pleasing and symmetrical display for the school dance buffet tables.

y = mx + b Which variable represents the slope?
Answers
The variable 'm' represent the slope.
What is slope?The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.
Given:
y= mx + b
The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line.
The net change in y coordinate is Δy, while the net change in the x coordinate is Δx.
So the change in y coordinate with respect to the change in x coordinate can be written as,
m = Δy/Δx
where, m is the slope
The slope of a line can be calculated from the equation of the line. The general slope of a line formula is given as,
y = mx + b
where,
m is the slope, such that m = tan θ = Δy/Δx
θ is the angle made by the line with the positive x-axis
Δy is the net change in y-axis
