[tex]\sf x=\boxed{18.21}[/tex]
Step-by-step explanation:
Assuming this is a right triangle.
Trigonometric ratios
[tex]\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleH is the hypotenuseGiven:
[tex]\theta[/tex] = 35°O = xA = 26[tex]\implies \sf \tan(35^{\circ})=\dfrac{x}{26}[/tex]
[tex]\implies \sf x=26\tan(35^{\circ})[/tex]
[tex]\implies \sf x=18.20539599...[/tex]
Therefore, x = 18.21 (nearest hundredth)
Find the volume, in cubic feet, of the solid with the regular base to the nearest tenth.
Answer:
Step-by-step explanation:
Remark
The base of the figure is a pentagon
The area of the base of a pentagon is
A=(1/4) * √[5(5+2√5)] * s2
The Formula for the Volume of a "pyramid" of this nature is
Volume = Base * h / 3
Givens
h = 10 feet
s = 8 feet
Base = formula in the remark section
Solution.
Find the base first.
A=(1/4) * √[5(5+2√ 5)] * s2 Find the value of 5 + 2√5
Area = 0.25√[5*(9.47)] * s^2 Find what is under the root sign
Area = 0.25√47.36 * s^2 Take the square root of 47.36. use s = 8
Area = 0.25 * 6.88 * 8^2 Combine.
Area = 110.11
Now find the volume
V = B * h/3
V = 110.11 * 10 / 3
V = 367.04 cubic feet.

Algebra Write an expression representing the volume of the composite figure
formed by a hemisphere with radius r and a cube with side length 2r.
The expression that represents the volume of the composite figure is 16/3πr³ + r³
The expression that represents the volume?The given parameters are:
Hemisphere radius = rCube length = rThe volume of a cube is:
V = l³
So, we have:
V = r³
The volume of a hemisphere is:
V = (2/3)πr³
So, we have:
V = (2/3)π(2r)³
Evaluate
V = (2/3)π * 8r³
This gives
V = 16/3πr³
Add both volumes
Volume = 16/3πr³ + r³
Hence, the expression that represents the volume of the figure is 16/3πr³ + r³

What do scientists believe are the descendants of dinosaurs?
A. Fish
B. Birds
C. Chimpanzees
D. Rats
Answer:
B
Birds are related to theropod dinosaurs — a group that includes the Tyrannosaurus rex.
Theropods were bipedal dinosaurs, meaning they walked on two legs, not four like many other dinosaurs. When we look at the modern-day emu or ostrich, the resemblance to these dinosaurs is striking, especially when examining their bone structure.
Birds have scales like many dinosaurs and some dinosaurs may have had feathers.
Scientists have discovered that the tissues used to produce scales in reptiles are similar to those that produce feathers in birds. This suggests that there is a common ancestor between dinosaurs, birds, and reptiles. Furthermore, birds have scales on their feet!
Birds lay eggs similar to dinosaurs and reptiles.
The similarities between bird and reptile eggs are well known, but they also share traits with dinosaur eggs.
Most dinosaur eggs are hard-shelled, just like the eggs of our modern-day feathered friends. They are also both made up of the same basic elements, calcium, and carbon, which form crystal structures that make the eggshell more difficult to crack.

In the problem: "63% of what number is 792?" the number being sought is the
Answer:
Set up an equation using these key terms:
63% can be considered 63/100'what number' can represent 'x'(our unknown value).'of' means multiplication'-is 792' means the product is equal to 792Form the equation by piecing these key terms together:
63/100(63%) ×(of) X(The number being sought) = 792("-is 792)
63/100 × X = 792
(63/100 can be simplified to 0.63)
So, rewrite the equation to:
0.63 × X = 792
Solve for x!
0.63x = 792
Isolate 'x' by dividing 0.63 from both sides because the inverse operation of multiplication is division.
÷0.63 ÷0.63
x = 1,257.14285714 which can be rounded to 1,257.14.
Therefore, the number being sought is 1,257.14.

Answer:
x = 0, mult: 3x = -4, mult: 2x = -5, mult: 2Step-by-step explanation:
When a polynomial is shown in factored form, its zeros are the values of x that make the factors zero.
The factor x is zero when x=0.
The factor (x+4) is zero when x=-4.
The factor (x+5) is zero when x=-5.
__
The multiplicity of a zero is the number of times a given factor is a factor of the polynomial. It is the exponent of the factor.
x = 0 has multiplicity 3.
x = -4 has multiplicity 2.
x = -5 has multiplicity 2.
What is a good first step to solve 4x + 3 = 15?
O Subtract 3 from both sides.
Combine 3 and 15 to make 18.
O Divide by 15.
O Add 4x and 3.
Divide both sides by 4.

Answer:
B: (x, y) --> (x + 4, y - 3)
Step-by-step explanation:
the shape DEF went to the right along the x axis wich increased x and then went down the y axis or decreased y to make D'E'F'
some good way to remember these translations and orders are...
- x is first when plotting points, then y (x, y)
- x increases going right, and decreases going left, as well as y increasing going up, then decreasing going down

which graph shows the image of the triangle after transforming at using the rule Z (x,y) (x,-y)
Answer:See the attached figure. The original triangle is shown in red (triangle ABC). The line of reflection is the blue dashed line. This is the equation y = x. Reflecting triangle ABC over the line y = x results in the purple triangle A'B'C'.
Note how the x and y values swap places.
We have...
point A = (5,1) turn into point A' = (1,5)
point B = (8,1) turn into point B' = (1,8)
point C = (8,6) turn into point B' = (6,8)
The swap occurs because the rule (x,y) --> (y,x) tells this to happen.
The purple triangle is the final answer.

What is the result of adding -3x²-5x +1 and 8x²-2x-9?
Hi!
Your answer is [tex]5x^2-7x-8[/tex].
We are asked:
[tex](-3x^2-5x+1)+(8x^2-2x-9)[/tex]
As we are adding them, we can remove the parenthesis.
[tex]-3x^2-5x+1+8x^2-2x-9[/tex]
Now, we can switch the order of the terms around to cause like terms to be by each other:
[tex]-3x^2+8x^2-5x-2x+1-9[/tex]
Finally, add like terms:
[tex]5x^2-7x-8[/tex]
5x² -7x -8 is the result of adding the polynomials -3x²-5x +1 and 8x²-2x-9. The result obtained by combining the like terms.
The two polynomials are -3x²-5x +1 and 8x²-2x-9.
To add the two polynomials, you simply combine like terms.
Like terms are terms that have the same variable raised to the same power.
In this case, the variables are x² and x.
Let's add the given polynomials:
= -3x²-5x +1 + 8x²-2x-9
Group the like terms:
= -3x²+ 8x²-5x-2x+1-9
Combine like terms:
= 5x² -7x -8
Hence, 5x² -7x -8 is the result of adding -3x²-5x +1 and 8x²-2x-9.

I think of a number. If I subtract 9 from it and multiply this difference by 4, the
result is 128.
Answer:
you were thinking of 41
Step-by-step explanation:
(x-9)*4=128
(x-9)=128/4
(x-9)=32
x=32+9
x=41
Answer:
41
Step-by-step explanation:
Let n be the number
Subtract 9
n-9
Multiply this by 4
4(n-9)
The result is 128
4(n-9)=128
To find the number divide each side by 4
4(n-9)/4=128/4
n-9 = 32
Add 9 to each side
n-9+9 = 32+9
n = 41

When you list all of the possible outcomes in a sample space by following an organized system (an orderly process), it is called a systematic list. There are different strategies that may help you make a systematic list, but what is most important is that you methodically follow your system until it is complete.
To get home, Renae can take one of 4 buses: #41, #28, #55, or #81. Once she is on a bus, she will randomly select one of the following equally likely activities: listening to her MP3 player, writing a letter, or reading a book.
a. Create the sample space of all possible ways Renae can get home and do one activity by making a systematic list.
b. Use your sample space to find the following probabilites:
i. P(Renae takes an odd-numbered bus)
ii. P(Renae does not write a letter)
iii. P(Renae catches #28 bus and then reads a book)
c. Does her activity depend on which bus she takes? Explain why or why not.
Answer:
Part (a)
see attached for sample space
Part (b)
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
Total number of possible outcomes = 12
[tex]\textsf{P(Renae takes an odd-numbered bus)}= \dfrac{9}{12}=\dfrac34[/tex]
[tex]\textsf{P(Renae does not write a letter)}= \dfrac{8}{12}=\dfrac23[/tex]
[tex]\textsf{P(Renae catches no.28 bus then reads a book)}= \dfrac{1}{12}[/tex]
Part (c)
Her activity does not depend on which bus she takes, as we have been told that once she is on the bus, she randomly selects the activity. Therefore, the activity selection is independent from the bus selection.
The sample space confirms this as it shows that the probability of the selecting each activity is equally likely for each of the 4 buses.

Given information:
y = 4x - 7. Through (3,1)
m = 4.
Thus, using m = 4 and point (3,1) in Point-Slope Form can make another equation that is parallel to y = 4x - 7.
[tex](y-y_0)=m(x-x_o)\\\\(y-(1))=4(x-(3))\\\\y-1=4(x-3)\\\\y-1=4x-12\\\\y=4x-11[/tex]
