From the figures and the properties of the parallelogram was possible to find that: UT=27, ST=18, RV=7 and US=14.
Quadrilaterals
There are different quadrilaterals, for example: square, rectangle, rhombus, trapezoid and parallelogram. Each type is defined accordingly to its length of sides and angles. For example, the opposite sides are equal and parallel, for a parallelogram. In a parallelogram is noted too that the opposite angles and the diagonals are equal.
From the properties: the opposite sides are equal and parallel for a parallelogram. It is possible to find:
UT=RS=27
ST=RU=18
Considering that UV=7, then VS= 7 since V is the midpoint of the diagonal US. Therefore, US=14.
From the property: the diagonals are equal for a parallelogram. It is possible to find:
US=RT=14
RV=RT/2=14/2=7

Answer:
m<LHK = 101
Step-by-step explanation:
Ok, so the straight line is equal to 180 degrees. And we already know the side of one angle, that is 79 degrees. So, simply subtract 79 from 180, and you get 101 degrees. I took geometry last year, and this might not be the "correct" way to do it, but it is easier and you get the same correct answer
Answer:
<LHK = 101
Step-by-step explanation:
angle on a straight line add up to 180
180 - 79 = 101
Evaluate each function for the given value of x , and write the input x and output f(x) as an ordered pair.
f(x) = (7/3)x-9 for x=3
f (3) = -2 is the output for the given input .
How can you tell whether a function is linear or not?
Looking at a function's graph will reveal if it is linear or not with the greatest ease.When a linear function is plotted on a graph, a straight line is formed. A nonlinear function is curved in some way; it does not form a straight line.f(x)= (7/3)x- 9
Put x = 3 ⇒ 7 * 3/3 - 9
⇒ 7 - 9
⇒ -2
Therefore f (3) = -2

What is the rate of change? x intercept is (-1,0) and b is -4 if that helps at all
Answer:
-4
Step-by-step explanation:
In this case, rate of change will be equivalent to the gradient of the line.
Standard form of Equation of Line:
y = mx + c
where
m = Gradient
c = y - intercept
From the given information, we can substitute x = -1 and y = 0, and c = b = -4 (y-intercept) to find m (Gradient)
0 = -1m - 4
m = -4
Therefore, the rate of change is -4.
An airplane flying at an altitude of 30,000 feet flies up to avoid a storm. Immediately after passing the storm, the airplane returns to its original altitude.
A. What interger represents the airplane's change in altitude to avoid the storm.?
B. What integer represents the airplanes change in altitude immediately after passing the storm?
C. Use appropriate tools, draw a number line to represent the airplanes changed altitude.
Answer: The number 8,000 represents the change in height necessary to dodge the storm.
The integer representing the altitude after passing the storm is 30,000
Use appropriate tools, draw a number line to represent the airplanes changed altitude = 34000
Step-by-step explanation:
In the picture that is attached, the diagram for this query is displayed.
We are informed that the aircraft's starting height was 30,000 feet.
A. What integer represents the airplane's change in altitude to avoid the storm.?
During the storm:
The plane flew at at altitude of 38,000 feet
We will deduct the end altitude from the starting altitude to obtain the change in altitude.
change of altitude = final altitude - initial altitude
change of altitude = 38,000 - 30,000
= 8,000 ft
Therefore, the integer representing the change of altitude to avoid the storm is 8,000
B. What integer represents the airplanes change in altitude immediately after passing the storm?
After the storm:
We are aware that the aircraft returned to its original height following the storm.
The number reflecting the altitude after passing the storm would be 30,000 ft given that the starting altitude is 30,000 ft.
C. Use appropriate tools, draw a number line to represent the airplanes changed altitude.
See a picture.
Use appropriate tools, draw a number line to represent the airplanes changed altitude = 34000

Traveling carnivals usually shut down for the winter months. Suppose a traveling carnival decided to instead remain open for business indefinitely in its last stop of the season. Assume its usual revenue projections hold($15,000 on the first nigh, and each night's revenue after the first night will be about 75% of the previous night revenue). To the nearest dollar, what is the maximum amount of revenue the carnival can expect in the town?
The maximum amount of revenue the carnival can expect in the town in the 5th night is; $4746.093.
How to solve Geometric Progression?A geometric progression is defined as a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
We are told that Revenue in the first night = $15000
Now revenue of new night is 75% of the previous night. Thus;
2nd night = 15000 × 75/100 = $11250
3rd night = $11250 × 75/100 = 8437.5
Therefore, the given geometric sequence is ;
15000, 11250, 8437.5 ...
First term; a = $15000
Common ratio (r) = 11250/15000 = 0.75
The formula for the nth term of a GP is given by ;
aₙ = arⁿ ⁻ ¹
Thus, revenue for the 5th night is;
a₅ = ar⁵⁻¹
a₅ = 15000(0.75)⁴
a₅ = 4746.093
We conclude that the revenue in the 5th night in two will be $4746.093.

yael used to have a square garage with 356ft ^2 of floor space. She recently built an addition to it. The garage is still a square but it now has 50% more floor space. What was the length of one side of the garage originally? What is the length of one side of the garage now? What was the percent increase in the length of one side?
The answers are given below:-
The length of one side of the garage originally was 17.9 ft.
The length of one side of the garage now is 21.9 ft.
The percent increase in the length of one side was 22.35%.
What is the area of a square?The area of a square of side s is given by s squared, that is:
A = s².
The original area was 320 ft², hence the original length was:
s² = 320
s = √(320)
s = 17.9 ft.
The area increased by 50%, hence the new area is:
A = 1.5 x 320 = 480 ft².
The current length of one side is:
s² = 480
s = √(480)
s = 21.9 ft.
The percent increase is the change divided by the initial length and multiplied by 100%, hence:
(21.9 - 17.9)/17.9 x 100% = 22.35%.
The percent increase in the length of one side was 22.35%.

20. The difference between the compound interest and the simple interest on a certain
Sum at 9% per annum for 2 years is 324. Find the sum.
The sum is 40,000.
The difference between compound interest and simple interest is 324 on a certain sum at 9% for 2 years.
So,
Compound interest - Simple interest = 324
C.I - SI = 324
The formula for compound interest is given as:
C.I = P( 1 + r/100 )ⁿ - P
Where P is the principal amount, r is the rate and n is the time in years.
Therefore,
C.I = P( 1 + 9/100)² - P
C.I = P( 1 + 0.09)² - P
C.I = P(1.09)² - P
C.I = 1.1881P - P
C.I = 0.1881P
Now, the formula for simple interest is given as:
S.I = ( P × R × T / 100 )
Where P is the principal amount, R is the rate and T is time in years.
Therefore,
S.I = ( P × 9 × 2 / 100 )
S.I = 18P / 100
S.I = 0.18P
Now,
C.I - S.I = 324
0.1881P - 0.18P 324
0.0081P = 324
P = 324 / 0.0081
P = 324 × 10000 / 81
P = 4 × 10000
P = 40000
Hence, the principal amount is 40,000.
