Answer: 8.6 Ft^2
Explanation:
First find the area of the WHOLE square in FEET
2.5 x 4.5 = 11.25 ft
Then we need to find the area of the circle
r = radius
The formula is A = 3.14r^2
The radius is .9166, we can tell because the total distance from top to bottom is 22in meaning 1.83333 ft, meaning the diameter is 1.8333, then to get the radius we cut that in half.
A = 3.14(.9166^2
A = 2.64 Ft
Now we need to find the new total area
11.25 - 2.64 = 8.61 in ^2
Now we need to convert it to the nearest tenth of a square foot
8.6 Ft^2

What is the expression and value of "six less than nine times the sum of a number and eight" when n = 5? 9 (n + 8) minus 6; when n = 5, the value is 111. 6 minus 9 (n + 8); when n = 5, the value is 111. 9 (n) + 8 minus 6; when n = 5, the value is 47. 6 minus 9 (n) + 8; when n = 5, the value is 47.
Answer:
Answer:
The expression is 9(n + 8) - 6, the value is 111 ⇒ answer A plz mark me brainlest
Step-by-step explanation:
* Lets explain how to solve the problem
- We have a statement:
" six less than nine times the sum of a number and eight"
- When we solve we will start by the last part
- The last part is the sum of a number and 8
- Assume that the number is n
∵ The sum is the answer of adding
∴ The sum of a number and eight is ⇒ n + 8
- Nine times the sum
∵ The sum is n + 8
∵ Nine times means multiply the sum by 9
∴ Nine times the sum is ⇒ 9(n + 8)
- Six less than nine times the sum
∵ Nine times the sum is 9(n + 8)
∵ Six less than means subtract 6 from nine times the sum
∴ Six less than nine times the sum is ⇒ 9(n + 9) - 6
* The expression is 9(n + 8) - 6
- Lets evaluate the expression when n = 5
∵ 9(n + 8) - 6
∵ n = 5
∴ The value = 9(5 + 8) - 6
∴ The value = 9(13) - 6
∴ The value = 117 - 6
∴ The value = 111
* When n = 5 the value of the expression is 111
Step-by-step explanation:
Answer:
The expression is 9(n + 8) - 6, the value is 111 ⇒ answer A

Please answer the following brainiest for whoever gets it and show work! :D
Step-by-step explanation:
Since I haven't gotten a reply, I'll just do area and circumference.
Area = pi(r^2)
Circumference: 2(pi)r
7) r = 4/3 yd
pi = 22/7
Area = (22/7)(4/3)^2 = 5 37/63
Circumference = 2(22/7)(4/3)
8) d = 8.4, r (radius) is 1/2 of d, so r = 4.2
pi = 3.14
Area = (3.14)(4.2)^2 = 55.3896
Circumference = 2(3.14)(4.2) = 26.376

Step-by-step explanation:
For this problem, you would only need to figure one of them out since all the numbers vary. I calculated the mean. Mean is the same as the average. First, add all the numbers up. I got 112. Then, divide 112 by the amount of numbers you added (8). 112/8 is 14, and the mean=14 is b.
A square has a perimeter of 76 cm. Each side measures x + 3.
What is the value of x, in centimeters?
The value of given x is 16
Given that:
Perimeter of square = 76 cm
Side of square = (x + 3)
Find:
The value of x
Computation:
Perimeter of square = 4[Side]
76 = 4[x + 3]
76 = 4x + 12
4x = 76 - 12
4x = 64
x = 64 / 4
x = 16
The value of x = 16

Write an equation for the line that is perpendicular to Y=-3/7x+4 and passes through (-4,-5)
9514 1404 393
Answer:
y = 7/3x +13/3
Step-by-step explanation:
The equation of the given line is in slope-intercept form (y=mx+b), so we can see the slope (m) is -3/7. The slope of the perpendicular line is the opposite reciprocal of this, so is ...
m = -1/(-3/7) = 7/3
The y-intercept of the perpendicular line can be found from ...
b = y -mx
b = -5 -(7/3)(-4) = -15/3 +28/3 = 13/3
Then the slope-intercept equation of the perpendicular line is ...
y = mx +b
y = 7/3x +13/3
_____
Additional comment
You can get there a little faster using the point-slope form of the equation of a line. For slope m and point (h, k) that form is ...
y -k = m(x -h)
For our perpendicular line, the equation is ...
y +5 = 7/3(x +4)

(x^2 + 8x + 8) + (-10x2 + 5x)
Answer:
-9x^2+13x+8
Step-by-step explanation:
Combine like terms-
(x^2 + 8x + 8) + (-10x^2 + 5x)
8x+5x = 13x
(x^2 + 8x + 8) + (-10x^2 + 5x)
-10x^2+x^2 = -9x^2
(x^2 + 8x + 8) + (-10x2 + 5x)
and 8 is just left over, so we put that all together and get...
-9x^2+13x+8

If I have 14 neutrons and 11 electrons, what is my mass number?
A.25
B.3
C.11
D.14
Answer:
A : 25
Step-by-step explanation:
In a neutral atom, the number of electrons is equal to the number of protons. The atomic number indicates the number of protons.
The mass number is the sum of the number of neutrons and the number of protons.
mass number=protons+neutrons
As we know from the atomic number, the number of neutrons is 14 and the number of electrons is 11.
mass number = 14 + 11

The equation for finding the circumference of a circle is: C=2πr
All we need to do is plug in for r of the equation (which is the radius) and solve.
C = 2(3.14)·12
C = 6.28 · 12
