Answer:
x = 5√3
Step-by-step explanation:
We will use the Pythagorean theorem with a and b as the lengths of the legs, and c as the length of the hypotenuse.
a² + b² = c²
We need two of the three lengths of a, b, and c, so we can find the third length.
The height divides the equilateral triangle into two right triangles.
Look at one of the right triangles.
One leg is half the side of the triangle.
a = 10/2 = 5
One leg is the height.
b = x
The hypotenuse is the side of the equilateral triangle.
c = 10
a² + b² = c²
5² + x² = 10²
25 + x² = 100
x² = 75
x = √75
x = 5√3
Answer: b

Which ordered pair is the solution to this system of equations?• y=x+4x + y = 21 (1,5)2 (0,2)3 (-1,3)4 (4.0)
Given the system of the equations:
y = x + 4
x + y = 2
By substitution with y from the first equation at the second equation
so,
x + (x+4) = 2
solve to find x
so,
x + x + 4 = 2
2x = 2 - 4
2x = -2
Divide both sides by 2
x = -2/2 = -1
Substitute at the first equation with x to find y
So, y = -1 + 4 = 3
so, x = -1 and y = 3
so, the order pair which a solution is (-1 , 3)

A patient is advised by his doctor to reduce his daily soda intake by 25%. Currently, he drinks 4.5oz. cans of soda per day. How many ounces of soda can the patient drink if he reduces his intake by 25%?
Answer: 3.375oz
Explanation
Given
• Reduce his daily soda intake by 25%.
,• Currently, he drinks 4.5oz. cans of soda per day.
,• Ounces of soda can the patient drink if he reduces his intake by 25%?
We have to build a relation, where 4.5 is our 100% and x is 75% (100 - 25 = 75%):
[tex]\frac{x}{75}=\frac{4.5}{100}[/tex][tex]x=\frac{4.5}{100}\cdot75[/tex]Solving for x:
[tex]x=4.5\cdot0.75[/tex][tex]x=3.375[/tex]The volleyball team has a record of 6 wins and 2 losses. What other team has a proportional win-loss record? Basketball: 12 wins, 5 losses Football: 3 wins, 1 loss Wrestling: 12 wins, 6 losses Debate: 3 wins, 4 losses
The number of win and losses of the volleyball team is related by a constant number, 3. This means that they're proportional. To find if the other teams also have proportional win-loss records we need to divide the number of their wins by the number of losses, if the result is an integer number, then they're proportional. We have:
[tex]\begin{gathered} \text{ basketball=}\frac{12}{5}=2.4 \\ \text{ football=}\frac{3}{1}=3 \\ \text{ wrestling=}\frac{12}{6}=2 \\ \text{ debate =}\frac{3}{4}=0.75 \end{gathered}[/tex]Since the football team has a proportional win-loss record with the same proportion as the Volleyball team, then this is the correct answer.

Challenging. A cylinder has a diameter of 12 inches at its base. The height of the cylinder is 1.25 feet. What is the volume of the cylinder in cubic inches? Use 3.14 for 7 and round your answer to the nearest cubic inch.
Diameter of cylinder = 12 inches
radius of cylinder (r) = 1/2 x diameter = 6 inches
Height of cylinder (h) = 1.25 feet
We can convert feet to inches using the relation: 1 foot = 12 inches
So, 1.25 feet = 12 x 1.25 inches
=> 15 inches
The volume of the cylinder is given by:
[tex]V\text{ = }\pi r^2\text{ h}[/tex]Upon substituting the values of r and h
[tex]\begin{gathered} V\text{ = 3.14 x 6 x 6 x 15} \\ \\ V=\text{ }1695.6\text{ cubic inches} \\ V=1696inches^3 \end{gathered}[/tex]

The equation of line perpendicular to another line in point slope form:
[tex]y-y_1 = -\frac{1}{m}(x-x_1)[/tex]
Substitute [tex]m=\frac{3}{2}[/tex] and the point [tex](-3,4)[/tex] into the above equation form:

find the slopes of the given points -5,-1 and -5,-10
The slope (m) of the given points is -9.
What do we mean by slopes?A line's steepness can be determined by looking at its slope. In mathematics, the slope is determined by dividing the change in y by the change in x, or "rise over run."Determine the coordinates of two points along the line that you choose. Find the difference between these two points' y-coordinates (rise). Find the difference between these two points' x-coordinates (run). Divide the difference in x-coordinates (rise/run or slope) by the difference in y-coordinates.So, the slope will be:
Slope formula: m = y₂ - y₁/x₂ - x₁Now, calculate as follows:
m = y₂ - y₁/x₂ - x₁m = -10 - (-1)/-5 - (-5)m = -10+ 1/-5 + 5m = -9/0m = -9Therefore, the slope (m) of the given points is -9.

Kayle is playing a game. She starts the game with 500 points. Her first 5 turns and the change in points are shown in the table.
How many points does Kayle have after her 5th turn?
Responses
−550 points
negative 550 points
−150 points
negative 150 points
350 points
350 points
1,150 points
Kayle have 1300 points after her 5th turn as the final score is sum of all score in the 5 rounds that come up to 1300.
What is addition?One of the four fundamental operations in mathematics is addition, along with subtraction, multiplication, and division. The total amount or sum of the two whole numbers is obtained by adding them. Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more numbers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation. When you add two or more numbers together, you get the sum of the numbers. The sum is the outcome of adding two or more numbers.
Here,
The final score will be the sum of all scores after 5th turn.
initial score=500
first round=−550 points
second round=−150 points
third round=350 points
fourth round=1,150 points
500+-550+-150+350+1150
=500-550-150+350+1150
=1300 points
After her fifth turn, Kayle had 1300 points because the total of her five rounds' scores added up to 1300.

The equation that could be used to solve for x is (3x-1) = 140 and the value of x is 47°.
According to the question,
We have the following information:
We have two lines that are intersecting each other at a point. The angles made on this point are given.
Now, we know that these two angles are vertically opposite angles. And we also know that vertically opposite angles are equal.
So, we will have the following equation:
3x-1 = 140
Now, we can easily find the value of x from this equation:
Adding 1 on both sides of the equation:
3x = 140+1
3x = 141
Dividing by 3 on both sides:
x = 141/3
x = 47°
Hence, the equation that could be used to solve for x is (3x-1) = 140 and the value of x is 47°.
