TUVW is a rectangle. Find the value of x and the length of each diagonal if
TV = 2x -4 and UW = x + 10.
--
*show your work please & giving brainliest to correct answer*
Answer:
The value of x is 14
The length of each diagonal is 24 units
Step-by-step explanation:
Let us revise the properties of the rectangle
Each two opposite sides are parallel and equalIts four vertices are right anglesIts diagonals equal each other and bisect each otherIn rectangle TUVW
∵ TV and UW are its diagonals
∴ TV = UW
∵ TV = 2x - 4
∵ UW = x + 10
- Equate them to find x
∴ 2x - 4 = x + 10
- Subtract x from both sides
∴ x - 4 = 10
- Add 4 to both sides
∴ x = 14
The value of x is 14
Substitute the value of x in the expression of TV OR UW to find the length of each diagonal
∵ TV = 2(14) - 4
∴ TV = 28 - 4
∴ TV = 24 units
The length of each diagonal is 24 units
Final answer:
To solve for x, we equate the lengths of TV and UW, since they are opposite sides of a rectangle. Solving the equation yields x = 14. We then find the lengths of TV and UW (both 24 units), and use the Pythagorean theorem to calculate the length of the diagonal, which is approximately 33.94 units.
Explanation:
We are given that TUVW is a rectangle with sides TV and UW. We are also given that the lengths of these sides can be expressed as TV = 2x - 4 and UW = x + 10. Since TUVW is a rectangle, opposite sides are equal in length, so TV equals UW.
Setting the expressions for TV and UW equal to each other gives us:
2x - 4 = x + 10Solving for x:
2x - x = 10 + 4x = 14Now we can find the lengths of TV and UW:
TV = 2(14) - 4 = 24UW = 14 + 10 = 24Therefore, each diagonal of the rectangle is of the same length because diagonals of a rectangle are congruent. We can use the Pythagorean theorem to find the length of the diagonal:
Let d be the length of the diagonal:
d² = TV² + UW²d² = 24² + 24²d² = 576 + 576d² = 1152d = √1152d ≈ 33.94The length of each diagonal of the rectangle is approximately 33.94 units.
Determine the center and radius of the following circle equation:
x2 + y2 - 6x + 6y - 82 = 0
Center:
Radius:
Pls help :)
The center of the given circle is at (3, -3), and the radius of the circle is 10. This can be determined by rearranging the equation into the standard form and then completing the square for the x and y terms.
To determine the center and radius of the circle given by the equation x2 + y2 - 6x + 6y - 82 = 0, we need to rearrange it into the standard form of a circle equation, which is (x - h)2 + (y - k)2 = r2, where (h, k) is the center and r is the radius of the circle.
First, group the x terms and the y terms: (x2 - 6x) + (y2 + 6y) = 82.
Then, complete the square for both x and y terms: (x2 - 6x + 9) - 9 + (y2 + 6y + 9) - 9 = 82. This factors to (x - 3)2 + (y + 3)2 = 82 + 9 + 9.
Finally, calculate the right side to find the radius squared: (x - 3)2 + (y + 3)2 = 100, so the circle's radius squared is 100 and the radius is 10.
Therefore, the circle's center is at (3, -3), and its radius is 10.

An element with mass 590 grams decays by 19.5% per minute. How much of the
element is remaining after 15 minutes, to the nearest 10th of a gram?
22.8 gms
Step-by-step explanation:
Step 1:
Given,
Mass of the element = 590 gms
Percentage decay per minute = 19.5%
Step 2 :
Fraction of the element remaining at the end of 1 minute = 1 - 0.195 = 0.805
Hence the fraction of element remaining after 15 minutes = [tex]0.805^{15}[/tex] = 0.03863
So the mass of the element remaining after 15 minutes = 0.03863 * 590 = 22.8 rounded off to the nearest 10th of a gram
mass of the element remaining after 15 minutes = 22.8 gms
Answer:
22.8

Step-by-step explanation:
Rational numbers are parts of a whole, expressed as fractions, decimals, or percentages. They are finite, recurring, and real.
Irrational numbers have no end to their numbers, and there is no pattern to the numbers. Besides perfect square roots (like 4, 9, 16, 25, etc.), all square roots are likely irrational. Anything with pi is irrational.

20 points! Identify the solids that form the compos
s that form the composite solid. Then find the surface area.
Round your answer to the nearest tenth.
The composite shape is made up of a cube with a side length of 5 inches and a cylinder with a radius of 2 inches and a height of 4 inches.
The composite solid's surface area is 225.4 square inches.
Step-by-step explanation:
Step 1:
The given composite shape is made up of a cube with a side length of 5 inches and a cylinder with a radius of 2 inches and a height of 4 inches.
The surface area of the composite shape is given by summing the individual surface areas.
The composite shape's surface area = The cube's surface area + the cylinder's surface area.
Step 2:
Any cube's surface area is calculated by multiplying 6 with the square of the side length ([tex]a^2[/tex]).
The cube's surface area = [tex]6a^2[/tex] = [tex]6(5^{2} )[/tex] = [tex]150[/tex] square inches.
Step 3:
Any cylinder's surface area is calculated with the following formula;
The cylinder's surface area = [tex]2 \pi r h+2 \pi r^{2}[/tex] = [tex]2 \pi (2) (4)+2 \pi (2)^{2}[/tex] = [tex]75.398[/tex] square inches
Step 4:
The composite shape's surface area = The cube's surface area + the cylinder's surface area.
The composite shape's surface area = 150 + 75.398 = 225.398 square inches. Rounding this off, we get the area as 225.4 square inches.

how do u find the value for y 6/8=y/16
Answer:
12 = y
Step-by-step explanation:
To make figuring this equation out easier, you will want to make all the fractions have the same denominator but stay equivalent to their original state. By this I mean, to get 6/8 to have the same denominator as y/16 but still be equivalent o 6/8, you will have to multiply it 2. That leaves you with 12/16 = y/16. Now that the equation has been modified, we can now solve it. You want to get the variable, y, isolated on one side of the equation. To do this, you want to multiply both sides of the equation by 16 since both sides of the equation are being divided by 16. This equation will look like this: 12/16 = y/16 --> 12 = y

A newspaper survey says that 424 people, or 53% of the people surveyed,
enjoy walking through the park. How many people were surveyed?
To find the total number of people surveyed when 424 people represent 53% of respondents, divide 424 by 0.53, which equals 800. Thus, 800 people were surveyed.
The question asks to determine the total number of people surveyed given that 53% of respondents enjoy walking through the park, and this represents 424 people. To find the total number of people surveyed, we set up a proportion where 53% (or 0.53) corresponds to the 424 people who enjoy walking in the park.
Using the formula for calculating percentages, we have:
Total people surveyed = 424 / 0.53
We perform the division to find the total number surveyed:
Total people surveyed = 800
Therefore, 800 people were surveyed.

-3x + 3y = 6
How many solutions can be found for the system of linear equations represented on the graph?
Solution:
Given system of equations are:
y = x + 2 ------ eqn 1
-3x + 3y = 6 -------- eqn 2
Solve the system of equations by substitution method
Substitute eqn 1 in eqn 2
-3x + 3(x + 2) = 6
-3x + 3x + 6 = 6
-3x + 3x = 6 - 6
0 = 0
If we end up with the same term on both sides of the equal sign, then we have infinite solutions
Thus the system of equations has infinitely many solutions

Answer:
y = -5/7x -32/7
Step-by-step explanation:
To find the perpendicular line, it is the opposite opposite slope. this means that you change if it was positive or negative, and you flip the numerator and the denominator. so, because this slope is positive, you turn it to be negative. then you would switch the numerator and denominator, making the slope of the other line -5/7 (m). then you use y=mx + b to find the equation of the other line. you use (2,-6) and fill in the values to find be, so you would do
-6 = (-5/7)(2) + b so then you solve
-6 = (-10/7) + b
-32/7 = b
and then you fill in the y=mx +b to get y = -5/7x -32/7
Can someone help me with this? Thank you :)
Answer: The area of the shaded region is 150.72 km^2
Step-by-step explanation: The first bit of information we have is that both the inner circle and the outer circle have the same center. The radius of the inner circle can be calculated since we have been given the circumference (25.12) and the value of pi (3.14). The circumference of a circle is given as
Circumference = 2 x Pi x radius
With the values available, we now have
25.12 = 2 x 3.14 x radius
25.12 = 6.28 x radius
Divide both sides of the equation by 6.28
radius = 4
Having calculated the radius of the inner circle, the area now becomes;
Area = Pi x radius^2
Area = 3.14 x 4^2
Area = 3.14 x 16
Area = 50.24 km^2
The radius of the outer circle is the addition of 4 (on the shaded region) to the radius of the inner circle and that gives us 8.
Next we calculate the area of the outer circle which is
Area = Pi x radius^2
Area = 3.14 x 8^2
Area = 3.14 x 64
Area = 200.96 km^2
Now that we have determined the area of both the inner circle and the outer circle, the area of the shaded region is simply the difference between both of them, that is
Area of shaded region = 200.96 - 50.24
= 150.72 km^2
