area of trapezium = 20 in^2
Step-by-step explanation:
here's your solution
==> area of trapezium = 1/2*(sum of parrel side)*distance between them
==> length of parrel sides = 6 in and 2 in
==> height = 5 in.
==> area of trapezium = 1/2(6 + 2) * 5
==> area of trapezium = 20 in^2

During the summer, Dwayne Works on his uncles dairy farm. One of Dwaynes Many chores is to load bales of hay onto a wagon and haul them from the field into the barn.
There is a proportional relationship between the number of wagon loads, x and the number of bales of hay Dwayne can haul, y.
What is the constant of proportionality? Write your answer as a whole number or decimal.
Answers
The constant of proportionality of the proportional relationship between the number of wagon loads, x and the number of bales of hay Dwayne can haul, y, is given as follows:
4.
How to define a proportional relationship?The standard definition of a proportional relationship is given as follows:
y = kx.
Hence the solution for the constant is given as follows:
k = y/x.
As the table represents a proportional relationship, the constant can be calculated from any pair, hence:
k = 20/5 = 4.

Erin has 4 cards, one with the letter A, one with the letter B, one with the letter C, and one with the letter D. She places the cards in a row in random order.
What is the probability that either the words BAD or CAB will appear as part of the row?
Answers
Answer:
P = 1/6
Step-by-step explanation:
We have 4 places where we can put the cards.
Let's count the number of possible outcomes for each place.
In the first place, we can put one of 4 cards.
in the second place, we can put one of 3 cards (because there is already one card in the first place)
In the third place, we can put one of 2 cards
In the last place, we can put one of one cards.
The total number of different combinations is the product between the number of options for each place, then we have:
C = 4*3*2*1 = 24
Now we need to count the number of combinations such that the words BAD or CAB appear.
Those are:
BADC
CBAD
CABD
DCAB
4 outcomes out of 24.
Then the probability will be equal to the quotient between the number of outcomes where one of these words appears (4) and the total number of possible outcomes (24)
The probability is:
P = 4/24 = 1/6
The probability would be 16.7%

This question needs the Pythagorean Theorem, which is a^2 + b^2 = c^2
a is a leg (opposite line to hypotenuse)
b is a leg (base line)
c is the hypotenuse (the diagonal line.)
3^2 + 4^2 = c^2
9 + 16 = c^2
25 = c^2
then you square root the number to the left to find c
square root of 25 is 5, since 5 x 5 is 25.

If you place a 37-foot ladder against the top of a building and the bottom of the ladder is 22 feet from the bottom of the building, how tall is the building? Round to the nearest tenth of a foot
Answers
Answer:
29.7 ft tall
Step-by-step explanation:
29.75ft. tall is the building.
What is Pythagorean theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
Here, we have,
from the figure , we get,
Hypotenuse = 37 ft.
Base= 22 ft.
Let, the building = height = x ft.
Now , by Pythagorean theorem, we have,
x=√37²-22²
=√885
=29.75
Hence, 29.75ft. tall is the building.

Review the table of values for function h(x).
x h(x)
8.9 3.83
8.99 –1.19
8.999 4.73
9 undefined
9.001 –4.73
9.01 1.19
9.1 –3.83
Which statement correctly explains whether Limit of h (x) as x approaches 9 exists?
The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9.
The limit does exist because h(x) is defined for all given values around x = 9, even though h(x) isn’t defined at x = 9.
The limit does not exist because h(x) is not defined at x = 9, and for a limit to exist, the function must be defined at x = 9.
The limit does exist because the values of h(x) to the right of x = 9 are all opposites of the values of h(x) to the left of x = 9.
Answers
Using lateral limits, the correct option is:
The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9.
------------------------------------
For a limit of a function f(x) to exist at a point a, it is needed that:
[tex]\lim_{x\rightarrow a^-} f(x) = \lim_{x\rightarrow a^+} f(x)[/tex]
That is, it has to approach a from both sides toward the same value, it cannot be oscillating.
These limits found, approaching a from close but smaller values, [tex][tex]\lim_{x\rightarrow a^-} f(x)[/tex], and from close but greater values, [tex]\lim_{x\rightarrow a^+} f(x)[/tex], are called lateral limits.
------------------------------------
From the table, looking at the value slightly less than 9, it can be said that: [tex]\lim_{x \rightarrow 9^-} f(x) = 4.73[/tex]Looking at the value slightly more than 9, it can be said that: [tex]\lim_{x \rightarrow 9^+} f(x) = -4.73[/tex]Since the lateral limits are different, the limit does not exist, and the correct option is:
The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9.
