ABCD is a parallelogram. If mZCDA = 81, then
mZDAB = ? _. The diagram is not to scale.
Answers
Answer:
∠DAB = 99°
Step-by-step explanation:
Given:
ABCD is PARALLELOGRAM
∠CDA = 81°
Find:
∠DAB
Computation:
ABCD is PARALLELOGRAM
So,
∠CDA + ∠DAB = 180°
81° + ∠DAB = 180°
∠DAB = 99°

what is the mean, median, mode and range of 7, 2, 1, 4, 1
Answers
1 + 1 + 2 + 4 + 7 = 15
15 / 5 = 3.
The median is the middle number in a list of numbers ordered from smallest to largest, so the median is 2.
1, 1, (2), 4, 7
The mode is the value that appears most often in a set of data. In this case, the mode is 1.
1: 2
2: 1
4: 1
7: 1
The range is the difference between the highest value and the lowest value, so the range here is 6.
Highest value: 7
Lowest value: 1
7 - 1 = 6

Bus A travels according to the function y = 125 /2 x where y is distance traveled in miles and x is time in hours. Bus B travels according to the graph below, where the distance y is a function of time x . Which bus travels faster? Include all necessary calculations in your final answer.
Answers
Answer:
Bus B travels faster.
Step-by-step explanation:
The graph of the question in the attached figure
we know that
the linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
x ---> is the time in hours
y ---> is the distance in miles
In this problem we have
Bus A
The slope of the linear equation represent the speed of the bus
so
The speed of bus A is
Bus B
Find the slope
take two points from the graph
(0,0) and (3,200)
The formula to calculate the slope between two points is equal to
substitute
Compare the slope Bus A with the slope Bus B
therefore
Bus B travels faster.

How can you tell if a pattern is quadratic or linear?
Answers
Answer: By finding the differences between the y-values, we can determine the degree of the model for the data.
If the first difference is the same value, the model will be linear.
If the second difference is the same value, the model will be quadratic.

Answer:
x = 33
Step-by-step explanation:
Because the parallel lines are intersected by two transversals, some parts of this figure correspond to each other. In order to solve this problem, you need to identify which sides correlate (you can tell they correlate because of the AAA property; if you extend the lines, a triangle with 2 parallel lines intersecting it would be formed, so you would see the three triangles are similar):
9 corresponds to 12
x corresponds to (x + 11)
Now, you need to find the scale factor by dividing 12 by 9:
12 ÷ 9 = 4/3
Since you know the scale factor is 4/3, you can now write and solve an equation:
4/3x = x + 11 (given)
1/3x = 11 (subtract x from both sides)
x = 33 (multiply both sides by 3)

a farmer has sheep and hen .the sheep and hen together have 100heads and 356 legs .how many sheep and hens does the farmer have?
Answers
Answer:
22 hens and 78 sheep
Step-by-step explanation:
Let the number of hens = x
Number of sheep = y
Total heads = 100
x + y = 100 --------------------(I)
x = 100 - y
Number of legs of 'x' hen = 2*x = 2x
Number of legs of 'y' sheep = 4*y = 4y
total legs = 356
2x + 4y = 356 -----------------------(II)
Substitute x = 100 -y in equation (II)
2(100 - y) + 4y = 356
2*100 - 2*y + 4y = 356
200 - 2y + 4y = 356 {Combine like terms}
200 + 2y = 356 {Subtract 200 from both sides}
2y = 356 - 200
2y = 156 {Divide both sides by 2}
y = 156/2
y = 78
Plugin y = 78 in equation (I)
x + 78 = 100
x = 100 - 78
x = 22
22 hens and 78 sheep
Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
y = 70(0.96)
Answers
Answer:
it is a decay, it's value drops by 4%
Step-by-step explanation:
0.96 is less than 1 so it is a decay function.
1-0.96 = 0.04 so it drops at the rate of 4%

Alice is standing on the roof of a 150 ft building. She looks down at an angle of depression of 15 degree and sees her friend bianca. How far away from the building is bianca
Answers
Answer:
559.70 ft
Step-by-step explanation:
Let D be the distance between building and Bianca.
Height of building H = 150 ft
Let there be a triangle ABC where, AC = height of building H= 150ft, AB = distance between Alice and Bianca and BC = D and therefore, ∠ABC = 15°.
Now in Triangle ABC , tanB = AC/BC
therefore, tan15° = 150/D
D = 150/tan15° = 559.70 ft
Therefore, the distance between building and Bianca D = 559.70 ft
