Given that ABCD is a parallelogram. Find the following
Answers
Answer:
m=8
m<A=83
m<D=97
Step-by-step explanation:
Angles that are opposite of each other in a parallelogram are equal. Knowing this, we can first conclude that angle A and angle C are equal. We can set up the following equation:
[tex]9m+11=8m+19[/tex]
Subtract both sides by 11
[tex]9m+11-11=8m+19-11\\9m=8m+8[/tex]
Subtract both sides by 8m
[tex]9m-8m=8m+8-8m\\m=8[/tex]
To calculate angle A, plug the value of m into its expression.
[tex]<A=9m+11\\<A=9(8)+11\\<A=72+11\\<A=83[/tex]
In a parallelogram, angles that share a side are supplementary, meaning they add up to 180 degrees. Therefore, angle A and angle D are supplementary. Knowing this, we can set up the following equation:
[tex]180=83+D[/tex]
Subtract both sides by 83
[tex]180-83=83+D-83\\97=D[/tex]

If you are making broccoli cheese soup the ratio of cheese to broccoli to broth is 5:6:10 if there is 100 parts broth how many of each ingredient should you use
Answers
Answer: See explanation
Step-by-step explanation:
Since there are 100 parts broth, the number to use for each ingredients will be:
Cheese = 5 × 100/10 = 5 × 10 = 50
Broccoli = 6 × 100/10 = 6 × 10 = 60
Broth = 100

Answer:
C
Step-by-step explanation:
I am not sure if it is B or C, but I can say that it is not A since the figure in A is rotated. Figure in B kinda looks like a reflection then C because if the figures were translated then the corner should be at one side. Sorry if that kinda confused you, but I added a picture of what I am trying to say for the figure in option B. I guess it is C.

A water rocket is launched froni a platform. The height,
h in metres, of the water rocket at time & seconds after
it is launched is h= -212 + 74 + 4. When does the water
rocket hit the ground?
Answers
Answer:
4.41seconds later
Step-by-step explanation:
Let the equation of the height reached by the water front be h = -2t^2+7t+4
The water hits the ground at h =0
Substitute
0 = -2t^2+7t+4
-2t^2+7t+4 = 0
2t^2 - 7t - 8 = 0
t = 7±√(-7)²-4(2)(-8)/2(2)
t = 7±√49+64/4
t = 7±√113/4
t = 7±10.63/4
t = 7+10.63/4
t = 17.3/4
t = 4.41s
Hence the water hit the ground 4.41seconda later

Actually Welcome to the Concept of the Equilateral Triangles.
Since, we know that, all the sides of a triangle are equal, hence it is a Equilateral triangle.
Equilateral triangle has one all angles equal to 60°.
so, major angle P = 60°
hence, 2x=60°
===> x = 30°
If x= 1/3 is one of the solutions of an equation then what is the factor that gave us this solution
Answers
Answer:
3x - 1 = 0
Step-by-step explanation:
If x = 1/3
multiply both sides by 3
3 * x = 1/3 * 3
3x = 1
Subtract 1 from both sides ;
3x - 1 = 1 - 1
3x - 1 = 0 ( the factor which gives the solution)
3x - 1 = 0
3x = 1
Doavide both sides by 3
3x / 3 = 1/3
x = 1/ 3

The number 6545 can be written as a product of a pair of positive two digit integers. What are these two integers?
Answers
Answer:
77 and 85
Step-by-step explanation:
Since the number 6545 ends in a 5, we can assume that one of the two digit numbers ends in a 5. I tried 55, 65, 75, and 85, and I just divided 6545 by those numbers until I got a two-digit positive integer as my answer,
85 * 77 = 6545
Therefore, the answer is 85 and 77.
I hope this helps!
