Answer:
triangle side = 0.54
so both triangle sides = 1.08
and then the sides (1.5 * 3.5) * 2 = 10.5
the last side = 0.9 * 3.5 = 3.15
so add it all 3.15 + 10.5 + 1.08
total area = 14.73 m^2

Step-by-step explanation:
The elevation of Location 1 is 20 feet above sea level and the elevation of Location 2 is 50 feet below sea level.
Which comparison of these locations is both true and correctly justified?
A. Because 20 < 50, Location 1 is higher.
B. Because 20 < 50, Location 2 is higher.
C. Because –50 < 20, Location 1 is higher.
D. Because –50 < 20, Location 2 is higher.
Answer:
C.
Step-by-step explanation:
Location 1 is 20 feet ABOVE the sea level while Location 2 is 50 feet BELOW the sea level.
Location 1 would be 20
Location 2 would be -50
And think of the greater than and lesser than symbol as a alligators mouth it would go towards the bigger number so, -50 < 20, Location 1 is higher, is the answer.
Chelsea buys a shirt and shoes at the store with the coupon. The price of the shirt before the discount is $22, and her total discount is $18.55. Write an equation to find a price of the shoes before the discount.
(THE COUPON IS IN THE PIC)
Answer: add 22 with $18.55 divide 50%
Step-by-step explanation:
As per linear equation, the equation to find the price of the shoe is: (11 + 0.5x) = 18.55.
The price of the shoe before discount is $15.1.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, 'x' is a variable, 'A' is a coefficient and 'B' is constant."
Given, the price of the shirt before the discount is $22.
Let, the price of the shirt before the discount is $x.
Now, total price of the shirt and shoe $(22 + x).
Now, the total discount on shirt and shoe is
= $(22 + x) × 50%
= $(22 + x) × 0.5
= $(11 + 0.5x)
Now, (11 + 0.5x) = 18.55
⇒ 0.5x = 18.55 - 11
⇒ x = 7.55 ÷ 0.5
⇒ x = 15.10
Therefore, the price of the shoe before discount is $15.1.

Which of the following represents a Pythagorean Triple? 1 {10, 20, 30} {5, 7, 10} {21, 72, 75} {11, 45, 60}
Answer:
F=dA
dF=0
d⋆F=⋆J
where in fact the second equality is not needed because of the identity d2=0 . In abstract tensor notation, these equations expand to
Fab=2∇[aAb]
∇[aFbc]=0
∇aFab=Jb
where in the above, additional compact notation has been used to simplify things: square brackets mean antisymmetrizing indices, and the covariant derivative ∇a is related to a flat derivative ∂a and a connection Γbac . Now, performing a 3+1 decomposition (here in flat space-time) Maxwell's equations break down as
∇⋅B⃗ =0
∇⋅E⃗ =4πρ
∂B⃗ ∂t=−∇×B⃗
∂E⃗ ∂t=+∇×B⃗ −4πJ⃗ .
In the above, there is yet more compactifying notation: the divergence is defined as
∇⋅v⃗ =∂vi∂xi
and the curl is defined as
(∇×v⃗ )i=ϵijk∂vk∂xj.
In the above, still more compactifying notation has been used, namely the Einstein summation convention. Written out in components, the divergence is
∇⋅v⃗ =∂vx∂x+∂vy∂y+∂vz∂z
and curl is defined as
(∇×v⃗ )z=∂vy∂x−∂vx∂y
and similarly for the other two components.
As you can see, the extremely compact and powerful notation
dF=0
d⋆F=⋆J
expands out to a large set of component equations—but they have the same content, so it's not very meaningful that the equations in components are much longer than in terms of differential forms.
As another example, Elson Liu answered with an exploded-out form of the Standard Model Lagrangian. However, it can be written much more compactly:
L=LYM+LHiggs+Llep.+Lqrk.+LYuk.
where
LYM=−14TrFabFab
LHiggs=−(Daϕ†)(Daϕ)+14λ(ϕ†ϕ−12v2)2
Llep.=iℓ†I/DℓI+ie¯†I/De¯I
Lqrk.=iq†I/DqI+iu¯†I/Du¯+id¯†I/Dd¯I
LYuk.=−yIJϕℓIe¯J−y′IJϕqId¯J
−y′′IJϕ†qIu¯J+h.c.
and specifying that F is the curvature on the gauge group G≃SU(3)⊗SU(2)⊗U(1) , Da is the gauge covariant derivative on G, /D is the gauge covariant Dirac operator on G, and specifying the representations of the fields: the scalar ϕ in the rep (1,2,-1/2), and the fermions ℓ in the rep (1,2,-1/2), e¯ in (1,1,+1), q in (3,2,+1/6), u¯ in (3¯,1,−2/3) , and d¯ in (3¯,1,+1/3) ; where I is a generation index running over 1,2,3, and where everything else is a constant.

A line passes through the points (-100,-9.5•10^3) and (300,3.05•10^4). Find the value of y when x =200. Write answer in scientific notation.Please help asap with details and steps on how to solve.
Answer:
2.05x10^4
Step-by-step explanation:
The equation of the line is y=100x+500, which can be found through the given points.
So, if x=200, plug that into the equation of the line. y=100(200)+500
y=20000+500
y=20500
In scientific notation, that is 2.05x10^4

Part 2) Equate the two pay equations: 20H = 10H + 50
Subtract 10H from both sides: 10H = 50
Then H = 5.
After 5 hours, each would have earned the same amount.

The table shows the approximate number of minutes of physical exercise each student in Noah’s class gets per day. Identify any outliers in the data set and explain how they affect the data.
I need an explanation please.
Answer:
120 and 180 minutes have outliers
Step-by-step explanation:
An outlier is a point of data in a data set that is far out from the median in the data set. In this case, almost all of the data points are from 0 minutes of exercise to 60 minutes, except for two that are more than double that.
It could "skew" the data, as if you were to calculate the mean (average), it would be shifted slightly higher by these two outliers.
Hope this helps!

30 books on the shelf are Fiction.
Step-by-step explanation:
Hey!
There are 50 books on a shelf.
1/5 of the books are Science Fiction.3/10 are Non-Fiction.The Rest are Fiction.how many books on the shelf are Fiction?
==================================================================
MAKE AN EQUATION!
We know that there are three Categories: Fiction, Science Fiction, and Non Fiction.
Total- 50
⇒ 50 =
1/5 of 50 are SF
⇒ 50 = (1/5)(50)
3/10 of 50 are NF
⇒ 50 = (1/5)(50) + (3/10)(50) + x
--------------------------------------------------------------------------------------------------------------
SOLVE THE EQUATION!
(1/5)(50) + (3/10)(50) + x = 50
To Isolate X-
-Multiply and remove the parentheses..
⇒ 50/10 + 150/10 + x = 50
-Simplify.
⇒ 5 + 15 + x = 50
-Add Like Terms
⇒ 20 + x = 50
-Subtract 20 from both sides.
⇒ 20 + x - 20 = 50 - 20
-Simplify Right Hand Side.
⇒ x = 30
--------------------------------------------------------------------------------------------------------------
So, 30 books on the shelf are Fiction.

Mr. Chang buys supplies for the school store. He bought 300 pencils on sale for $10. During the first three months of school, he sold 200 pencils and made $50. The other pencils were thrown away because they were broken. How much profit did Mr. Chang make on the pencils?
Answer:
$40
Step-by-step explanation:
He bought the pencils for $10, so his expense was $10. He sold the pencils for $50, and $50 - $10 is $40, and that's the total amount of money he made.
