Find area of the composite figure
Answer:
517 sq. cm
Step-by-step explanation:
Area of the figure = area of triangle + area of semicircle
Area of semi circle = πr²/2
Area of semi circle = 3.14*15²/2
Area of semi circle = 353.25 sq.cm
Area of the triangle = a/2 * base * height
Base = 30cm
Height h² = 39² - 15²
h² = 1521 - 225
h² = 1296
h = 10.90cm
Area of triangle = 1/2 * 10.90 * 30
Area of triangle = 15 * 10.90
Area of triangle = 163.5 sq. cm
Area of figure = 353.25 + 163.5
Area of figure = 516.75 sq. cm
Area of figure = 517 sq. cm

Answer: [tex]\frac{7}{8}[/tex] or 0.875 in decimal form.
Step-by-step explanation:
Okay, so to solve this, the easiest method is to find a common denominator. While we could try using trial and error or if you know your tables really well, I don't so we will just multiply the denominators which is 8 and 4. We then multiply 8 and 4 which is 32.
To convert the fractions we have, we multiply both the numerator and denominator of each, by the multiple that multiplies the denominator to 32.
[tex]\frac{2}{4}[/tex] multiply both 4 and 2 by 8. Now we have [tex]\frac{16}{32}[/tex].
Same thing with the second number. We have [tex]\frac{3}{8}[/tex]. We multiply both the numerator and the denominator by 4. 3*4 is 12, 8*4 is 32.
Now we have [tex]\frac{12}{32}[/tex].
Now that both fractions have common denominators, we can add the numerators. [tex]\frac{16}{32} +\frac{12}{32} = \frac{28}{32}[/tex]
Now we have the answer, [tex]\frac{28}{32}[/tex], but is that it?
No. Now to find the final two answers, we simply [tex]\frac{28}{32}[/tex].
To simplify, we find the Greatest Common Factor of 28 and 32, which in this case happens to be 4. This is the highest number that either of those can be divided by to provide a normal whole number
After solving [tex]\frac{28/4}{32/4} =\frac{7}{8}[/tex]
That is our final answer. [tex]\frac{7}{8}[/tex].
If necessary, you can convert it to decimal form through simple division and end up with 0.875.
Which is a prime number 63 , 7, 27, 33
Answer:
7
Step-by-step explanation:
63 can be divided by 3, 7, 9, 21
27 can be divided by 3, 9
33 can be divided by 3, 11
Answer:
The correct answer is 7.
Step-by-step explanation:
A prime number is a number whose factors only include 1 and that number itself, examples of prime numbers would be 2 (1; 2), 5 (1; 5), and 11 (1; 11). In order to find the prime number, you must calculate all factors in each number. 63 has the following factors: 1; 3; 7; 9; 21; 63, so it isn't a prime number. 27 has the following factors: 1; 3; 9; 27, so it isn't a prime number. 33 has the following factors: 1; 3; 11; 33, so it also isn't a prime number. 7 only has two factors, 1 and 7, meaning that it is a prime number. Hence, this would be the correct answer.

The Martz family pays a rate of 37.5 mills the property tax versus value of the home is 68,000 what is the property tax
If the property tax versus value of the home is 68,000 the property tax is $2,550.
Property taxUsing this formula
Property tax=Mills rate× Property value /1000
Where:
Mills rate=37.5
Property value=$68,000
Let plug in the formula
Property tax=37.5×68,000/1000
Property tax=$2,550,000/1000
Property tax=$2,550
Or
Convert the mills rates to dollar rate amounts by dividing the mill rate by 1,000 and then multiply it by the property value.
Property tax=37.5/1000×$68,000
Property tax=$2,550
Inconclusion the property tax is $2,550.

When rolling a pair of dice, what is the probability (as a percent) that each die will land on an even number?
Answer:
The probability of getting an even number at the first die is 1/2 (as the probability of even = the probability of odd = 1/2); 2. The probability of getting a total of 8 is 5/6^2, as there are 5 different favorable scenarios: (2,6), (6,2), (3,5), (5,3) and (4,4);

In your own words, what does human rights mean to you
Answer:
Hello Dear!❤Step-by-step explanation:
I could give a definition and list all of the international treaties. I could describe the obligations that states have to protect and defend human rights. I could get into the details in so many ways. But I won’t. And the reason why is because, in the end, it’s so simple. Human Rights are about recognizing the humanity in each person.
I guess you could get depressed and feel hopeless after four days of films and discussions about serious human rights issues like genocide and honour violence. But for me, at the end of this first Lund Human Rights Film Festival, the solution to many of our problems seems clearer than ever.
Hope that helps you..
Buhbye!

The equation of three other functions are given which function or functions have a slope equal to the slope of Function 1
Answer:
See Explanation
Step-by-step explanation:
Required
Function(s) with the same slope as function 1
The question is incomplete as function 1 and the three additional functions are not given.
However, I will provide a general explanation.
A slope is represented as:
[tex]y = mx + b[/tex]
Where
[tex]m \to[/tex] slope
So, considering the following equations
[tex]y = 2x + 3[/tex]
[tex]y = \frac{3x}{2} + 9[/tex]
[tex]y = 2x - 5[/tex]
[tex]y = -2x + 3[/tex]
The following equations have the same slope
[tex]y = 2x + 3[/tex] and [tex]y = 2x - 5[/tex]
Because: [tex]y = mx + b[/tex] implies that:
[tex]m = 2[/tex] for [tex]y = 2x + 3[/tex] and [tex]y = 2x - 5[/tex]
