The surface area of a three dimensional shape is the total area of all of the faces. To find the surface area of a shape, we find the area of each face and add them together. E.g. The measurements here are in centimetres so the surface area is measured in square centimetres ( c m 2 ) (cm^2) (cm2).

4 blue + 5 red + 3 black = 12 chips in total.
p=probability
1st draw:
p (blue) = 4/12
there are now 11 chips in the bag, 4-1 =3 are blue.
2nd draw?
p (blue) = 3/11
probability of pulling one blue chip followed by another blue chip is:
(4/12) X (3/11) = (4X3)/12X11)

The number properties rule is a set of rules that help you solve mathematical equations. The rule is also known as the order of operations. The acronym PEMDAS is used to remember the order of operations. It stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right) ¹².
Let's solve the equations using the number properties rule:
A) 5 + 16 = 16 + __
We can solve this equation by subtracting 16 from both sides of the equation.
5 + 16 - 16 = 16 + __ - 16
5 = 16
The equation is not true.
B) 450 + ___ = 50 + 450
We can solve this equation by subtracting 450 from both sides of the equation.
450 + ___ - 450 = 50 + 450 - 450
___ = 50
The answer is 50.
C) 2 + ( 3 + 5 ) = ( 2 + 3 ) + _____
We can solve this equation by simplifying the parentheses first.
2 + (3 + 5) = (2 + 3) + _____
2 + 8 = 5 + _____
10 = 5 + _____
We can solve this equation by subtracting 5 from both sides of the equation.
10 - 5 = 5 - 5
5 = _____
The answer is 5
D) (7 + 4) + 6 = ___+ (4+6)
We can solve this equation by simplifying the parentheses first.
(7 + 4) + 6 = ___+ (4+6)
11 + 6 = ___+ 10
17 = ___+ 10
We can solve this equation by subtracting 10 from both sides of the equation.
17 - 10 = ___+ 10 - 10
7 = ___
The answer is 7
E) 7 + 0 = ________
The answer is 7
F) 15 – 0 = _______
The answer is 15
G) (12 – 8 ) – 2 = _______
We can solve this equation by simplifying the parentheses first.

Area of middle rectangle is,
A = (11 - (3 + 5)) x (8 - 2)
A = 3 × 6
A = 18 cm²
Area of lower rectangle is,

Refer to the step-by-step.
Step-by-step explanation:
Verify the given identity.
[tex]E_0\cos^4(\theta)=E_0(\frac{1}{2} +\frac{\cos(2\theta)}{2} )^2[/tex]
Pick the more complex side to manipulate, in this case it is the R.H.S.
(1) - Apply the following double-angle identity
[tex]\boxed{\left\begin{array}{ccc}\text{\underline{Double-Angle Identity:}}\\\\\cos(2A)=1-2\sin^2(A)\end{array}\right}[/tex]
[tex]E_0(\frac{1}{2} +\frac{\cos(2\theta)}{2} )^2\\\\\Longrightarrow \boxed{ E_0\Big(\frac{1}{2} +\frac{1-2\sin^2(\theta)}{2}\Big )^2}[/tex]
(2) - Split of the right fraction
[tex]E_0(\frac{1}{2} +\frac{1-2\sin^2(\theta)}{2} )^2\\\\\Longrightarrow E_0(\frac{1}{2} +\frac{1}{2} -\frac{2\sin^2(\theta)}{2})^2\\\\\Longrightarrow \boxed{E_0(1 -sin^2(\theta))^2}[/tex]
Apply the following Pythagorean identity
[tex]\boxed{\left\begin{array}{ccc}\text{\underline{Pythagorean Identity:}}\\\\1-\sin^2(A)=\cos^2(A)\end{array}\right}[/tex]
[tex]E_0(1 -sin^2(\theta))^2\\ \\\Longrightarrow E_0(\cos^2(\theta))^2\\\\\therefore \boxed{E_0\cos^4(\theta)=E_0\cos^4(\theta)}[/tex]
Thus, the identity is verified.
It has been proven and verified that [tex]E_0cos^4 \theta = E_0(\frac{1}{2} +\frac{cos2 \theta}{2} )^2[/tex] below.
How to verify the equality of the cosine function?In Mathematics and Geometry, the standard equation of a cosine function is represented or modeled by the following mathematical equation (formula):
y = Acos(Bx - C) + D
Where:
A represents the amplitude.B = 2π/P.P represents the period.C represents the phase shift.D represents the center line (midline).In this exercise, you are required to prove that the right-hand side of the cosine function is equal to left-hand side of the cosine function;
[tex]E_0cos^4 \theta = E_0(\frac{1}{2} +\frac{cos2 \theta}{2} )^2[/tex]
From the double-angle formulas, we have:
2sin²θ = 1 - cos2θ
cos2θ = 1 - 2sin²θ
Next, we would evaluate the right-hand side of the cosine function by substituting "1 - 2sin²θ" for cos2θ as follows;
[tex]E_0cos^4 \theta = E_0(\frac{1}{2} +\frac{1-2sin^2 \theta}{2} )^2\\\\E_0cos^4 \theta = E_0(\frac{1}{2} +\frac{1}{2} -\frac{2sin^2 \theta}{2})^2\\\\E_0cos^4 \theta = E_0(1 -\frac{2sin^2 \theta}{2})^2\\\\E_0cos^4 \theta = E_0(1 -sin^2 \theta)^2\\\\[/tex]
E₀cos⁴θ = E₀(1² - (sin²θ)²)
E₀cos⁴θ = E₀(1 - sin⁴θ) ⇒ (Verified).

Therefore, the perimeter of the triangle is 3x, which is given to be 30 inches.
On simplifying , we get
3x = 30
x = 10
Now, we know that the height of an equilateral triangle is given by the formula:

If the Coach chooses the Three-Year Plan, what is the total amount he will spend after 12 months? ANSWER QUICK ILL GIVE BRAINLIST!
Answer:
$17,320 after 12 months.
Step-by-step explanation:
f the Coach chooses the Three-Year Plan, the total amount he will spend after 12 months can be calculated as follows:
First, we need to calculate the total amount of monthly payments made in 12 months:
12 months x $610 per month = $7,320
Then, we need to add the down payment made at the time of purchase:
$7,320 + $10,000 = $17,320
Therefore, if the Coach chooses the Three-Year Plan, he will spend a total of $17,320 after 12 months.

If a town's population doubles every 4 years, how

current population is 28,100? y = ab*
The population of the town 12 years later will be 224,800 if the current population is 28,100 and the population doubles every 4 years.
Since the population doubles every 4 years, we can use the formula:
P = P0 x [tex]2^{t/4}[/tex]
where P0 is the initial population, t is the time elapsed in years, and P is the population after time t.
In this case, the initial population P0 is 28,100, and we want to know the population after 12 years, so t = 12. Substituting these values into the formula, we get:
P = 28,100 2^(12/4)

y intercepts of f((x)=x^{2}+2x-3
Answer:
The y-intercept is -3
Written as a point it is (0, -3)
Step-by-step explanation:
To find the y-intercept, let x = 0
(and to find x-intercepts, let y = 0)
So let's let x = 0
f(x) = x^2 + 2x - 3
y = x^2 + 2x - 3
y = 0^2 + 2(0) - 3
y = -3

In a certain Integrated Math II class of 29 students, 6 of them play golf and 14 of them play soccer.
There are 9 students who play neither.
Number of students that play = 20
let, students play golf = A
students play soccer = B
so, given that,
n ( A) = 6 and, n ( B) = 14
so, total sample space = 29
now, P(A) = 6/29
P(B) = 14/29
and, P(students who play neither) = 9/29
we get, 6/29 + 14/ 29 + 9/29 = 29/29 = 1
i.e. there are no students who play both golf and soccer = 0
all the events are independent.
so, we have,
the probability that a student chosen randomly from the class plays golf or soccer = P(A) + P(B)
