What is the area of a regular pentagon with a side length of 10 inches and a distance from the center to a vertex of 10 inches? Round your answer to the nearest tenth.
Answer:
[tex]A=172.04\ in^2[/tex]
Step-by-step explanation:
Given that,
The side length of a regular pentagon = 10 inches
The distance from the center to a vertex of 10 inches
The formula for the area of a regular pentagon is given by :
[tex]A=\dfrac{1}{4}\sqrt{5(5+2\sqrt{5} } }\ a^2[/tex]
Put a = 10
So,
[tex]A=\dfrac{1}{4}\times \sqrt{5(5+2\sqrt{5} )} \times 10^2\\\\A=172.04\ in^2[/tex]
So, the area of a regular pentagon is equal to [tex]172.04\ in^2[/tex].

Find the volume of the cylinder in terms of x and to the nearest tenth
Answer:
12.57 in^3
Step-by-step explanation:
The easiest way to do this is to find the area of the circle surface and multiply it by the height
to find area the formula is pi r^2 and we are given the radius
so we plug in pi(2^2)=pi(4)= roughly 12.57
then we multiply the area by the height which is 1 so it would be the same
12.57(1)=12.57
The area of the base of a box is 825 square centimeters. It has a height of 26 centimeters. What is the volume of the box in cubic centimeters?
Answer: 4950 cubic centimeters.
Step-by-step explanation:
We know that, the volume of box = Base area x height
Given: area of the base of a box = 825 sq. centimeters
height = 6 centimeters.
Then, Volume of the box in cubic centimeters = 825 x 6
= 4950 cubic centimeters.
hence, the volume of the box in cubic centimeters = 4950 cubic centimeters.

Expand the brackets. 7 ( 5 + g ) 11 ( 3s – 4 ) 4 ( 4 – x ) 8 ( 6 + 4w )
Answer:
See answers below
Step-by-step explanation:
Expand the brackets. 7 ( 5 + g ) 11 ( 3s – 4 ) 4 ( 4 – x ) 8 ( 6 + 4w )
We will expand each of the bracket using distributive property
For the expression 7(5+g)
7(5)+7g
= 35+7g
For the expression 11(3s-4)
= 11(3s)-11(4)
= 33s-44
For the expression 4(4-x)
= 4(4)-4x
= 16-4x
For the expression 8(6+4w)
= 8(6)+8(4w)
= 48+32w
A data set is normally distributed with a mean of 27 and a standard deviation of 3.5.
Find the.z-score for a value of 25, to the nearest hundredth.
Answer: -0.57
Step-by-step explanation:
z-score: data - mean / standard deviation
25 - 27 / 3.5
= -0.57

I need help with this graph! I need to solve this equation to understand where to graph the points, I really need help on this ty :)
(you don't need to actually graph it just tell me where to put the points please!)
What’s the answer to this?!!
Answer:
52
Step-by-step explanation:
Using the reverse Pythagorean Theorem we can get the answer quite easily. If A^2 + B^2 = C^2, then by that same logic, C^2 - A^2 = B^2. That means 62^2, or 3844, minus 39^2, or 1521, equals 2323. The square root of that is 52.
Hope that this helps!

Use the order of operations to help you solve,
56 + 9x2
100 + 5 X4
8 X 12 - 6
Answer:
See below for steps and answers, but answers are:
74
5
90
Step-by-step explanation:
Order of operations is: PEMDAS = parentheses, exponents, multiplication, division, addition, subtraction
1. 56 + 9 x 2
first we multiply:
= 56 + 18
then we add:
=74
-----------------------
2. 100 / 5 x 4
first we multiply:
= 100 / 20
then we divide 100 by 20:
= 5
-----------------------
3. 8 x 12 - 6
first we multiply:
= 96 - 6
then we subtract:
= 90

Twenty years ago, Mr. Davis purchased his home for $160,000. Since then, the value of
the home has increased about 5% per year. How much is the home worth today?
Answer:
The home is worth $424,528 today
Step-by-step explanation:
To get the worth of the home today, we are going to use the exponential formula
We have this as follows;
A = P(1 + r)^t
where A is the value of the house after some time t
P is the initial value the home was worth which is $160,000
r is the rate of increase in the price of the home which is 5% = 5/100 = 0.05
t is the number of years which is 20
substituting these values;
A = 160,000(1 + 0.05)^20
A = $424,528

6(x + 3) - (x + 4) = -11
Answer: x=-5
Step-by-step explanation:
Distribute
6(x+3)-1(x+4)=-11
6x+ 18-1(x+4)=-11
6x +18-x-4=-11
Subtract the numbers
6x +18-x-4=-11
6x +14-x=-11
Combine like terms
6x +14-x=-11
5x +14=-11
subtract 14 from both sides of the equation
5x +14=-11
5x +=14-14 = -11 -14
simplify
5x=-25
divide both sides
x=-5
