A
O A. 19.5
B. 78
O C. 15.8
O D. 26
E. 52
ОО
F. Cannot be determined
Answer:
A. 19.5
Step-by-step explanation:
Diagonals of a rhombus intersect at right angles. Therefore the angle opposite to AD = 90°.
Thus:
90° + x + 3x + 12 = 180° (sum of ∆)
Add like terms
102 + 4x = 180
Subtract 102 from each side
4x = 180 - 102
4x = 78
Subdue both sides by 4
x = 19.5

(Solve for r) 56 = 7r
Also explain how you got it.
Answer:
r=8
Step-by-step explanation:
56=7r
first I simplified the equation to the form, which is simple to understand
56=7r
Then I move all terms containing r to the left and all other terms to the right.
-7r=-56
Next I simplified the left and right the side of the equation.
-7r=-56
Then i divided both sides of the equation by -07 to get r.
r=8

Using the remainder theorem see if (x-2) and (x+5) are factors of the polynomial
X^2+3x-10
Answer:
See explanations below
Step-by-step explanation:
Given the polynomial function
P(x) = X^2+3x-10
To check whether x-2 and x+5 are factor, we will find x and then show that P(x) = 0
For x-2
x - 2 = 0
x =2
P(2) = 2²+3(2)-10
P(2) = 4+6 -10
P(2) = 10-10
P(2) = 0
Since the remainder is zero, hence x-2 is a factor of the polynomial
Similarly for x+5;
x+5 = 0
x = -5
P(-5) = (-5)²+3(-5)-10
P(-5) = 25-15-10
P(-5) = 10-10
P(-5) = 0
This also shows that x+5 is a factor

[tex]\angle 2 = 101[/tex]
[tex]\angle 3 = 101[/tex]
[tex]\angle 4 = 101[/tex]
Step-by-step explanation:
Given
The attachment
Require
Solve for [tex]\angle 1, \angle 2, \angle 3, \angle 4[/tex]
We start by solving for [tex]\angle 1[/tex]
[tex]\angle 1 + 79 = 180[/tex] ---- Angle on a straight line
[tex]\angle 1 + 79-79 = 180 - 79[/tex] --- Subtract 79 from both sides
[tex]\angle 1 = 101[/tex]
[tex]\angle 1 = \angle 2 = \angle 3[/tex] --- Corresponding angles;
So, we have:
[tex]\angle 2 = 101[/tex]
[tex]\angle 3 = 101[/tex]
[tex]\angle 1 = \angle 4[/tex] --- vertically opposite angles
So, we have:

X = 2
2) 2(x-5)= -5
2x - 10 = -5
2x = 5
x = 2.5
4) -0.5(2x+6) = -6
-x -3 = -6
-x = -6+3
-X = -3 ( both negative will get cancel)

A scientist graphed the locations of the epicenterof an earthquake and all of the places wherepeople reported feeling the earthquake. Shepositioned the epicenter atmath(−1,8)and thefarthest location reported to have felt thequake was positioned at (85, 8). If each unit onthe graph represents 1 mile, how far from itsepicenter was the earthquake felt?
the earthquake was felt as far as approximately 86 miles away from its epicenter.
How to find what is an earthquake?
The epicenter of the earthquake is located at (-1,8), and the farthest reported location where people felt the earthquake is located at (85,8).
We can calculate the distance between these two points using the distance formula:
d = √((x2 - x1)²2 + (y2 - y1)²2)
where (x1,y1) = (-1,8) is the epicenter and (x2,y2) = (85,8) is the farthest reported location.
Substituting the values into the formula, we get:
d = √((85 - (-1))²2 + (8 - 8)²2)
Simplifying, we get:
d = √((86)²2 + (0)²2)
d = √(7396)
d ≈ 86 miles
Therefore, the earthquake was felt as far as approximately 86 miles away from its epicenter.
An earthquake is a sudden and rapid shaking of the Earth's surface, caused by the movement of tectonic plates beneath the Earth's crust. Earthquakes can vary in size and intensity, from minor tremors to major seismic events that can cause significant damage and loss of life.

Gideon is filling a container with sand. How much sand will fit in the container
Answer:
418cm³
Step-by-step explanation:
volume of cuboid=l×b×h=11×2×19=418c³
Answer:
418 square centimeters.
Step-by-step explanation:
Since the formula for volume is length times width times height, you would have to multiply 11 (length) times 2 (width) first, and you would get 22. Next, you have to multiply 22 with the height (19). After you do this you will get your final answer which is 418 square centimeters.

Hey there!
Given the following system:
4x + y = 8
-3x - y = 0
We do not need to change the equations at all, because the "y"s will already cancel eachother out. When we add the equations together, we get
x = 8
Now, we have to solve for y: We can do so by plugging in the value of x in to one of the equations:
4(8) + y = 8
Now we solve:
4(8) + y = 8
32 + y = 8
y = -24
The solution to the first given system is (8, -24)
Now, we can check by plugging the numbers into both equations, and seeing if they are true:
4(8) + (-24) = 8
32 + (-24) = 8
8 = 8 ~ TRUE
Now, we check the second equation:
-3(8) - (-24) = 0
-24 - (-24) = 0
-24 + 24 = 0
0 = 0 ~ TRUE
Both equations are true, which means that the correct solution to the first given system is (8, -24)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For the second given system, we are going to have to change one of the equations because, when added, the "x" or "y" values will not cancel out.
3x + 5y = 54
6x + 4y = 72
We can divide the second equation by -2 so the "x" values will cancel out:
-3x - 2y = -36
Now, we add the equations:
3y = 18
And solve for "y":
3y = 18
y = 6
Now, we plug the "y" value into one of the equations and solve for "x":
3x + 5(6) = 54
3x + 30 = 54
3x = 24
x = 8
The solution to the second given system is (8, 6)
Now, we can check by plugging the "x" and "y" values into both equations:
3(8) + 5(6) = 54
24 + 36 = 54
54 = 54 ~ TRUE
Now, we check the second equation:
6(8) + 4(6) = 72
48 + 24 = 72
72 = 72 ~ TRUE
Both equations are true, which means that the correct solution to the second given system is (8, 6)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For P(x) = 2x^4 – 5x^3+x-10, use synthetic substitution to evaluate P(-2). P(1), and P(2).
Answer:
P(-2) = 2(-2^4) - 5(-2^3) + (-2) -10
= 2(16) - 5(-8) + (-2) - 10
= 32+40-2-10
= 60
P(1) = 2(1^4) - 4(1^3) + (1) - 10
= 2 - 4 + 1 - 10
= -11
P(2). = 2(2^4) - 5(2^3) + (2) - 10
= 2(16) - 5(8) + 2 - 20
= 32-40+2-10
= -20
