In the diagram, the area of the given shape is 102 cm²
Area of a KiteFrom the question question, we are to determine the area of the given shape
The given shape is a kite
The area of a kite is given by the formula,
[tex]A =\frac{pq}{2}[/tex]
Where A is the area
p and q are the diagonals
In the given diagram,
p = 6cm + 6 cm = 12 cm
q = 3 cm + 14 cm = 17 cm
Thus,
Area of the kite = [tex]\frac{12 \times 17}{2}[/tex]
Area of the kite = 6 × 17
Area of the kite = 102 cm²
Hence, the area of the given shape is 102 cm²

Step-by-step explanation:
all the elements are associated with only one second element except -4
for -4 there are two second elements 3 and 5 from the ordered pairs (-4, 3) and (-4, 5)
so we can remove one of them to make R a function
since (-4, 3) is not in the options so the correct option is (-4, 5)

Savannah is 1.75 meters tall. At 11 a.m., she measures the length of a tree's shadow to
be 43.75 meters. She stands 39.2 meters away from the tree, so that the tip of her
shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest
hundredth of a meter.
The height of the tree is 1.95 meters.
At 11 AM, we have
Savannah = 1.75 m
Tree Shadow = 43.75 m
Savannah Shadow = 39.2 m
So, we make use of the equivalent ratio
Savannah :Tree::Savannah Shadow:Tree Shadow
Now, 1.75:Tree::39.2:43.75
In fraction Tree/1.75 = 43.75/39.2
Multiply both sides by 1.75
Tree =43.75/39.2 ×1.75
Tree=1.95
Therefore, the height of the tree is 1.95 meters.

Step-by-step explanation:
In the right triangle of XYZ, Given that angle Z=90 degrees, angle X=58 degrees and XZ=4.9m.
Since it's a right triangle you can use SOHCAHTOA:
cosθ=adjacent/hypotenuse
cosθ=4.9/h

It takes a word processor 33 minutes to process and spell check 6 pages. Find out how long it takes her to process and spell check 28 pages.
Answer:
154 minutes to process and spell check 28 pages
Step-by-step explanation:
33 Minutes to process 6 pages
If we divide both of these numbers by 6 we will get the time taken to process 1 page
33 ÷ 6 = 5.5 minutes, and 6 ÷ 6 = 1 page
So 5 and a half minutes per page
To find out how long 28 pages will take, we multiply by 28
5.5 × 28 = 154 minutes, and 1 × 28 = 28 pages
Which gives us the time of 154 minutes to process and spell check 28 pages

1. The loan balance after 2 years is $45,262.
2. The loan balance after 3 years is $42,678.
3. The loan balance after 1 year is $47,700.
What is the loan balance?The loan balance is the amount remaining from the principal amount after the deduction of repayment and the addition of interest for the period.
The loan balance can be computed manually as below:
Data and Calculations:Loan amount = $50,000
Interest rate = 6%
Annual repayments = $5,000
1st year:
Loan amount = $50,000
Repayment = ($5,000)
Interest = $2,700 ($50,000 - $5,000) x 6%
Loan balance = $47,700 ($50,000 - $5,000 + $2,700)
2nd year:
Loan balance = $47,700
Repayment = ($5,000)
Interest = $2,562 ($47,700 - $5,000) x 6%
Loan balance = $45,262 ($47,700 - $5,000 + $2,562)
3rd year:
Loan balance = $45,262
Repayment = ($5,000)
Interest = $2,416 ($45,262 - $5,000) x 6%
Loan balance = $42,678 ($45,262 - $5,000 + $2,416)
Thus, the loan balance after 3 years is $42,678.

what percent is 38 of 80
Answer:
47.5
Step-by-step explanation:
38/80x100%=47.5
Answer:
47.5%
Step-by-step explanation:
Before we get started in the fraction to percentage conversion, let's go over some very quick fraction basics. Remember that a numerator is the number above the fraction line, and the denominator is the number below the fraction line. We'll use this later in the tutorial.
When we are using percentages, what we are really saying is that the percentage is a fraction of 100. "Percent" means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form.
So, since our denominator in 38/80 is 80, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:
100 ÷ 80 = 1.25
ow we can see that our fraction is 47.5/100, which means that 38/80 as a percentage is 47.5%.
We can also work this out in a simpler way by first converting the fraction 38/80 to a decimal. To do that, we simply divide the numerator by the denominator:
38/80 = 0.475
Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:
0.475 x 100 = 47.5%
And there you have it! Two different ways to convert 38/80 to a percentage. Both are pretty straightforward and easy to do, but I personally prefer the convert to decimal method as it takes less steps.
I've seen a lot of students get confused whenever a question comes up about converting a fraction to a percentage, but if you follow the steps laid out here it should be simple. That said, you may still need a calculator for more complicated fractions (and you can always use our calculator in the form below).
If you want to practice, grab yourself a pen, a pad, and a calculator and try to convert a few fractions to a percentage yourself.
Hopefully this tutorial has helped you to understand how to convert a fraction to a percentage. You can now go forth and convert fractions to percentages as much as your little heart desires!
What is the volume, in cubic meters of the prism below?
Answer:
1848 Cubic Meters
Step-by-step explanation:
The volume should be (7*24*22)/2
This is because this object is bascally half of a rectangular prism, so we need to divide the whole product by 2 at the end.
7*24*22 = 3696
3696/2 = 1848
A city’s population has been growing linearly. In 2008, the population was 28,200. By 2012, the population was 36,800. Assuming this trend continues, which of the following is a linear function that properly models the relationship between the town's population, P, and the years that have passed since 2008, t.
The linear function that models the relationship is P = 28,200 + 1950t.
What is the linear function that models the relationship?A linear function is a function that has a single variable raised to the power of 1. An example is x + 2
The first step is to determine the rate of increase in the population:
Rate of increase = (population in 2012 - population in 2008) / number of years
(36.000 - 28,200) / 4 = 1950
P = 28,200 + 1950t
