Answer:
Length of DE = 22.8cm
Step-by-step explanation:
Given: 23° and 8.9cm
To find the length of DE, we need to use the SOH-CAH-TOA method.
Since DE is the hypotenuse (The longest side), we need to use SOH meaning sinФ([tex]\frac{opposite}{hypotenuse}[/tex]).
The opposite of the angle, 23° is 8.9cm, by replacing the formula with the given, we would get the following: sin(23°)=([tex]\frac{8.9}{x}[/tex]).
To calculate, we need to multiply 'x' to both sides: x*sin(23°) = 8.9
Using a calculator, sin(23°) is 0.39
0.39x = 8.9
By dividing 0.39 to both sides, we should end up with 22.8cm (rounded to the nearest tenth of a centimeter).

<12 and <11 are not linear pairs to <14
Explanation:
A linear pair is created when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

The Pythagorean Theorem can be used to find the distance between points (3, 2) and (6, 4). Select all the points that could be the third vertex in the triangle.
Sorry, he gave you a false answer :/
Answer:
(3,4) and (6,2) could be vertices of a right triangle with (6,4) and (3,2)
(0,0) is on the same line as (6,4) and (3,2) so it doesn't even form a triangle, much less a right triangle.
(3,6) forms a scalene isosceles triangle, but not a right triangle It's a 4-sqr13-sqr13 triangle

Answer:
rational
Step-by-step explanation:
A rational number can be expressed in the form

adrian has 4 hits and 10 at bats and dustin has 3 hits and 8 at bats
based on their hits hits to at bats ratios who would you expect to have more hits in a game marlon or dustin?
Answer: Marlon
Step-by-step explanation:

What is the value of x?
Answer: x = 27
Step-by-step explanation:
The angles (4x + 7) and 5(x - 4) are opposite angles formed by intersecting lines.
When intersecting lines form two sets of opposing angles, both pairs are equal in angle measure.
As such, the angles (4x + 7) and 5(x - 4) are equal. Knowing this, you can solve for x by setting the angles equal to each other in an equation:
[tex](4x + 7) = 5(x - 4)\\\\4x + 7 = 5x - 20\\\\27 = x[/tex]
X = 27.
Which of the following is the maximum value of the equation?
Answer:
y = - x^2 + 2x + 5
= -(x^2 - 2x + 1) + 6
= -(x - 1)^2 + 6
-(x - 1)^2 always smaller or equal to 0
=> y is smaller or equal to 6
=> Option A is correct

How many solutions for x does the following equation have? 4/5 (20x+5) = 16x-2 A. infinite B. 1 C. -2 D. 0
Answer :
A. infinite
Step by step4/5 (20x + 5) = 16x - 2
16x + 4 = 16x - 2
16x - 16x = -2 - 4
0x = -6
x = -6/0
x = infinite
The equation has zero solution.
What is the solution to a linear equation?The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.
Given here, the expression as 4/5 (20x+5)=16x-2
80x+20 = 80x-10
20 =- 10 which is not possible
Hence, the equation has no solution and thus D is the correct option.

Answer:
measure of variability
Step-by-step explanation:
Measure of variability shows the extent in which data in a statically distribution differ from an average value as well as how they differ from each other. It shows how much the data falls from the center value (mean) showing the width of the distribution. The most used measures of variability are the range, interquartile range, variance, and standard deviation depending on the data to be measured.

Plz help!!! Calvin is filling the pool in his backyard with water. If the pool is in the shape of a cylinder with a diameter of 12ft and a height of 5 ft, how much water is needed to fill a 3/4 of the pool?
Answer:
424.1175
Step-by-step explanation:
Volume of the total pool = π[tex]r^{2}[/tex]h
= π x [tex]6^{2}[/tex] x 5
= 565.49
needed to fill a 3/4 of the pool = [tex]\frac{3}{4}[/tex] x 565.49
= 424.1175
Considering the volume of a cylinder, the amount of water needed to fill a 3/4 of the pool is 135π ft³.
Definition of volumeVolume is a measure of the space occupied by an object in three-dimensional space, using cubic units to measure it. The volume formula depends on the shape of the figure and its different dimensions.
Volume can be considered as the capacity of a container to hold a quantity of fluid (gas or liquid).
Volume of a cylinderIn the case of a cylinder, it is characterized by having two circular bases and a surface that joins the two bases. So the volume of a cylinder is π×r²×h.
Amount of water neededIn first place, you must know that the length of the radius is half the length of the diameter.
On the other side, it is needed to fill a 3/4 of the pool.
Then, considering the definition of volume and the expression of volume of a cylinder, the amount of water needed is calculated as:
amount of water=(3/4)×π×(12 ft ÷2)²× 5 ft
Solving:
amount of water=(3/4)×π×(6 ft)²× 5 ft
amount of water= 135π ft³
Finally, the amount of water needed to fill a 3/4 of the pool is 135π ft³.
