Answer:
h = 12
surface area = 192
Step-by-step explanation:
Volume of this prism = 72
The base triangle has an area of B * h/2
The base = 6
The height in red = 2
Area = 1/2 * 6 * 2
Area = 6 ft^2
The volume = B * h = 72
The base = 6
6* h = 72
h = 72/6
h = 12
The surface area = 2 triangles + the rectangle face closest to us + the rectangular face whose width is 4 + rectangular face whose with is 5
The surface area = 2 * 6 + 6* 12 + 4*12 + 5 * 12
The surface area = 12 + 72 + 48 + 60
The surface area = 192 square feet.

The principal amount of $2,287.26 from compound interest at a rate of 4.5% per year owed after six years on a loan of $1300
Since n is the number of times the interest is compounded each year, and 'r' is the rate of compound interest annually, sothe final amount after 't' years would be:
\(a = p(1 + \dfrac{r}{n})^{nt}\)
Given that certain loan program offers an interest rate of 4.5%, compounded continuously.
Assuming no payments are made so;
First, convert R as a percent to R as a decimal
r = R/100
r = 4.5/100
r = 0.045 per year,
Then, solve the equation for P
P = A / (1 + r/n)^nt
P = 1300/ (1 + 0.045 /365)(365)^(15)
P = 1300/ (1 + 0.00010137)^(4745)
P = $2,287.26

Step-by-step explanation:
A rug cleaning company sells three models. EZ models weighs 10 pounds, packed in a 10-cubic-foot box. Mini model weighs 20 pounds, packed in an 8-cubic-foot box. Hefty model weighs 60 pounds, packed in a 28-cubic-foot box. A delivery van has 296 cubic feet of space and can hold a maximum of 440 pounds. To be fully loaded, how many of each should it carry if the driver wants the maximum number of Hefty models?
From the information that the question gives us, we have that models:
EZ weights 10 pounds, Box = 10 cubic-foot, represented by letter E
Mini weights 20 pounds, Box = 8 cubic-foot, represented by letter M
Hefty weights 60 pounds, Box = 28 cubic-foot, represented by letter H
The van can hold on a maximum of 440 pounds and has 296 cubic-feet. We have the following equations, to get the optimal solution:
For the weight:
\(10E+20M+60H=440\)For the volume:
\(10E+8M+28H=296\)\(\begin{gathered} 10E+20M+60H=440 \\ -(10E+8M+28H)=296 \end{gathered}\)We subtract the two equations to get:
\(12M+32H=144\)Divide the above equation by 4, to simplify the equation:
\(3M+8H=36\)Now we express M in terms of H:
\(\begin{gathered} 3M=36-8H \\ M=\frac{36-8H}{3} \end{gathered}\)Now we start looking for integer solutions for the above equation, given that we want to maximize H, we can look for integer solutions starting with the largest possible, which is 4. But H=4 does not give an integer solution for M. We can try with H = 3
\(\begin{gathered} M=\frac{36-8\cdot3}{3} \\ M=4 \end{gathered}\)Great, now that we have the number of M (Mini models), we can find the number of Hefty models and EZ models,
For H (Hefty models) we replace M in 3M+8H=36, and solve for H:
\(\begin{gathered} 3\cdot4+8H=36 \\ 12+8H=36 \\ 8H=36-12 \\ H=\frac{24}{8}=3 \end{gathered}\)To find E, we can take the first equation 10E+20M+60H=440, to express E in terms of H and M, replace and solve:
\(\begin{gathered} 10E+20M+60H=440 \\ 10E=440-20M-60H \\ E=44-2M-6H \\ E=44-2\cdot4-6\cdot3=18 \end{gathered}\)M = 4
H = 3
E = 18
A rectangular piece of metal is 5 in longer than it is wide. Squares with sides 1 in lòng are cut from the four corners
and the flaps are folded upward to form an open box. If the volume of the box is 234 in³, what were the original
dimensions of the piece of metal?
The original dimensions of the piece of metal were 15 inches by 20 inches.
To solve this problem, we can use the given information to set up an equation. Let's assume that the width of the rectangular piece of metal is x inches. According to the problem, the length of the piece of metal is 5 inches longer than its width, so the length would be (x+5) inches.
When squares with sides 1 inch long are cut from the four corners, the width and length of the resulting box will be reduced by 2 inches each. Therefore, the width of the box will be (x-2) inches and the length will be ((x+5)-2) inches, which simplifies to (x+3) inches.
The height of the box will be 1 inch since the flaps are folded upward.
Now, let's calculate the volume of the box using the formula Volume = length * width * height.
Substituting the values, we have:
234 = (x+3)(x-2)(1)
Simplifying the equation, we get:
234 = x^2 + x - 6
Rearranging the equation, we have:
x^2 + x - 240 = 0
Now, we can solve this quadratic equation either by factoring or by using the quadratic formula. Let's use factoring to find the values of x.
Factoring the equation, we have:
(x+16)(x-15) = 0
Setting each factor equal to zero, we get:
x+16 = 0 or x-15 = 0
Solving for x, we have:
x = -16 or x = 15
Since the width cannot be negative, we take x = 15 as the valid solution.
Therefore, the original dimensions of the piece of metal were 15 inches in width and (15+5) = 20 inches in length.

What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between the sides and angles of a right-angle triangle. The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
It discusses how triangle side lengths and angles relate to one another. Using trigonometric formulas and functions, it is mostly used to determine the unknown side lengths and angles of a right-angled triangle. Six different functions are frequently employed in trigonometry.
It is given that tan(A)=5 and tan(B)=9
As we know,
\(\rm tan(A -B) = \frac{tan A - tan B}{1- tan A tan B}\)
Substitute the given values we get,
tan(A -B) = (tan A - tan B)/(1 + tan A tan B)
tan(A -B) = (5-9) / (1 + 5 × 9)
tan(A -B) = (-4) / (1 + 45)
tan(A -B) = -4 / 46
tan(A -B) = -2/23
tan(A -B) = - 0.086
Thus ,if tan(A)=5 and tan(B)=9 the value of tan(A−B) will be -0.086.

The one-to-one functions g and h are defined as follows
Answer:
\(g^-^1(x)=-8\)
\(h^-^1(x)=\frac{x-4}{3}\)
\((h^-^1 \ o\ h)(-3)=-3\)
Step-by-step explanation:
When given the following functions,
\(g=[(-2,-7),(4,6),(6,-8),(7,4)]\)
\(h(x)=3x+4\)
One is asked to find the following,
1. Question 1
\(g^-^1(4)\)
When finding the inverse of a function that is composed of defined points, one substitutes the input given into the function, then finds the output. After doing so, one must substitute the output into the function, and find its output. Thus, finding the inverse of the given input;
\(g^-^1(4)\)
\(g(4)=6\\g(6)=-8\\g^-^1(4)=-8\)
2. Question 2
\(h^-^1(x)\)
Finding the inverse of a continuous function is essentially finding the opposite of the function. An easy trick to do so is to treat the evaluator (h(x)) like another variable. Solve the equation for (x) in terms of (h(x)). Then rewrite the equation in inverse function notation,
\(h(x)=3x+4\\\\h(x)-4=3x\\\\\frac{h(x)-4}{3}=x\\\\\frac{x-4}{3}=h^-^1(x)\)
\(h^-^1(x)=\frac{x-4}{3}\)
3. Question 3
\((h^-^1 \ o\ h)(-3)\)
This question essentially asks one to find the composition of the function. In essence, substitute function (h) into function (\(h^-^1\)) and simplify. Then substitute (-3) into the result.
\(h^-^1\ o\ h\)
\(\frac{(3x+4)-4}{3}\\\\=\frac{3x+4-4}{3}\\\\=\frac{3x}{3}\\\\=x\)
Now substitute (-3) in place of (x),

how many whole numbers are between 1 and 50 that are divisible by 2?
Answer:
25
Step-by-step explanation:
The first number in the range 1 - 50 that is divisible by 2 is 2 itself. Then 4, 6, 8, ....
Here's one way to think and count:
\(2 \rightarrow 1\\4 \rightarrow 2\\6 \rightarrow 3\\8 \rightarrow 4\\\vdots\\50\rightarrow 25\)
In the table, the number on the right is half the number on the left. The numbers on the right are just counting numbers (natural numbers), so there are 25 even numbers between 1 and 50.
in an equilateral triangle the first side is x+1, second side is 2x+4, the third side is 3x+y, find the value of x and y
The value of x is -3 and y is 7 for equilateral triangle having x+1, 2x+4 and 3x+y sides.
We can use the fact that an equilateral triangle has equal lengths on each of its three sides to determine the values of x and y.
Given:
First side=x+y
second side= 2x+4
third side=3x+y
An equilateral triangle has three equal sides, hence the following equations can be constructed:
x + 1 = 2x + 4
2x + 4 = 3x + y
Let's tackle each of these equations separately:
x + 1 = 2x + 4
We will subtract x from both sides and subtract 4 from both sides in order to solve this equation:
x + 1 - x = 2x + 4 - x
1 = x + 4
By taking 4 away from both sides, we arrive at:
1 - 4 = x + 4 - 4 , -3 = x
Therefore, x has been determined to be -3.
Now, substitute the value of x in the second equation:
2x + 4 = 3x + y
2(-3) + 4 = 3(-3) + y
-6 + 4 = -9 + y
-2 = -9 + y
y = -2 + 9
y = 7
So, we determined that y has a value of 7.
As a result, the values of x and y are, respectively, x=-3 and y=7

brainly.com/question/32094907?referrer=searchResults
Answer:
Step-by-step explanation:
In an equilateral triangle all sides are equal.
So each of these sides (and their equations are equal to each other.)
To find x - set the first two (as they only involve x) equal to each other and solve.
x + 1 = 2x + 4
x -x + 1 = 2x - x + 4
1 = x + 4
1- 4 = x + 4 - 4
-3 = x
Then substitute -3 for x in the last equation to find y, also setting it equal to one of the other equations.
3(x) + y = x + 1
3(-3) + y = -3 + 1
-9 + y = -2
-9 + 9 + y = -2 + 9
y = 7
so x = -3 and y equal 7
