The area of a semicircle is 39.25 square kilometers. What is the semicircle's radius?
Use 3.14 for pi
__ kilometers
Answer:
R=5
Step-by-step explanation:
The area of a semi circle is 1/2(pi×R^2).
Since the area is given you would just work backwards.
Using 3.14 as "pi", you would have
39.25 = 1/2(3.14×R^2)
39.25*2 = 3.14*R^2
78.5 = 3.14* R^2
78.5/3.14 = R^2
25 = R^2
Then you would take the sqrt of R and 25
And the answer would come to 5 = R
R= radius
[tex] \small \tt{Area \: of \: a \: semicircle = \frac{1}{2} \times \pi {r}^{2} }[/tex]
[tex] \small\tt{39.25 = \frac{1}{2} \times 3.14 \times {r}^{2} } [/tex]
[tex] \small\tt{39.25 \times 2 = 3.14 \times {r}^{2} } [/tex]

cube is a 3D square basically
so you can do the volume
2 * 1 * 7/4
14/4
14/4 and you divide it by 1/4
14/4 ÷ 1/4 or 14/4 * 4/1

full prism volume: 2 * [tex]\frac{7}{4}[/tex] * 1 = 3.5 cm³
volume of single cube: ([tex]\frac{1}{4}[/tex])³ = [tex]\frac{1}{64}[/tex] cm³

Select the correct answer from the drop-down menu. Find the polynomial. {5} is the solution set of.
Polynomials are expressions. The polynomial whose solution set is {5} is x²-10x+25.
What are polynomial?Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.
As it is given that the {5} is the solution set of the function, therefore, we can write,
[tex]x = 5\\(x-5 )= 0[/tex]
Thus, (x-5) is one of the factors of the polynomial.
Let's assume that the 5 is the only root of the polynomial, therefore, if we multiply the factor by itself we will get the quadratic equation whose solution is only 5.
[tex](x-5)^2\\\\\text{Using the algebric identity we will get}\\\\x^2-10x+25[/tex]
Hence, the polynomial whose solution set is {5} is x²-10x+25.

what is x - 2 5/8 = 6 1/4
Answer:
x = 7 5/8
Step-by-step explanation:
Given:
x - 2 5/8 = 6 1/4
first, let's find a common denominator so we can deal with the fractions easier.
The smallest number 8 and 4 is divisible by, is 8.
so we just multiply everything in the equation by 8 now, this helps get rid of the fractions.
x - 2 5/8 = 6 1/4
8 (x -2 5/8) = 8 (6 1/4)
simplifies into
8x -16 + 5 = 48 + 2
simplify some more
8x -11 = 50
solve for x
8x = 11 + 50
8x = 61
x = 61/8
or
x = 7 5/8
Answer:
Decimal: x=8.87
Improper fraction: x=71/8
Mixed number: x=8 7/8
Step-by-step explanation:
[tex]x-2\frac{5}{8}=6\frac{1}{4}[/tex]
First, let's convert mixed numbers to improper fraction
[tex]x-\frac{21}{8}=\frac{25}{4}[/tex]
Now, we can add 21/8 to both sides
[tex]x-\frac{21}{8}+\frac{21}{8}=\frac{25}{4}+\frac{21}{8}[/tex]
[tex]x=\frac{71}{8}[/tex]
We can convert 71/8 to a mixed number
[tex]x=8\frac{7}{8}[/tex]
