Find the area of this trapezoid. Be sure to include the correct unit in your answer.
Answer:
A = 55 in²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₁ the parallel bases
Here h = 5, b₁ = 5 and b₂ = 17 , then
A = [tex]\frac{1}{2}[/tex] × 5 × (5 + 17) = 2.5 × 22 = 55 in²
Answer: 55
Step-by-step explanation: A=a+b
2h=5+17
2·5=55

She can expect to hit the bullseye 5 times.
Answer:
A. 5
Step-by-step explanation:
Regina throws 25 darts and hits the bullseye 20% of the time. So we would set up the equation as 0.20*25 (as we are looking for 20% of 25 and of means multiplication and 20% is 0.20). 0.20*5=5 so she can expect to hit the bullseye 5 times. Therefore, A is the correct answer choice.

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.

Ms. Leeper gives her sixth- and seventh-grade students a geography test to decide who will represent her class in the school geography bee. The line plots below show the results of the test for her sixth-grade class and seventh-grade class, respectively.
The data for each grade have the same interquartile range (IQR). Which of the following best compares the two test score distributions?
A - The median score of the seventh-grade class is 2 points greater than the median score of the sixth-grade class. This difference is the same as the IQR.
B - The median score of the seventh-grade class is 2 points greater than the median score of the sixth-grade class. This difference is twice as much as the IQR.
C - The median score of the seventh-grade class is 3 points greater than the median score of the sixth-grade class. This difference is the same as the IQR.
D - The median score of the seventh-grade class is 3 points greater than the median score of the sixth-grade class. This difference is twice as much as the IQR.
What is the median of this data
10,11,14,10,14,11,15
I think 11 is the median for the data.

Meg plotted the graph below to show the relationship between the temperature of her city and the number of sweaters sold at a store:
Main title on the graph is Sweater Sale. Graph shows 0 to 30 on x axis at increments of 5 and 0 to 12 on y axis at increments of 1. The label on the x axis is Temperature in degree C, and the label on the y axis is Number of Sweaters Sold. Dots are made at the ordered pairs 0, 12 and 2.5, 10 and 2.5, 11 and 5, 10 and 7.5, 9 and 7.5, 10 and 10, 7 and 12.5, 6 and 12.5, 8 and 15, 4 and 15, 7 and 17.5, 5 and 20, 1 and 20, 3 and 22.5, 9 and 25, 1 and 27.5, 1.
Part A: In your own words, describe the relationship between the temperature of the city and the sale of sweaters in the city. (5 points)
Part B: Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate slope and y-intercept. (5 points)
Solution:
The description about the graph is:
Graph shows 0 to 30 on x axis at increments of 5 and 0 to 12 on y axis at increments of 1. The label on the x axis is Temperature in degree C, and the label on the y axis is Number of Sweaters Sold. Dots are made at the ordered pairs 0, 12 and 2.5, 10 and 2.5, 11 and 5, 10 and 7.5, 9 and 7.5, 10 and 10, 7 and 12.5, 6 and 12.5, 8 and 15, 4 and 15, 7 and 17.5, 5 and 20, 1 and 20, 3 and 22.5, 9 and 25, 1 and 27.5, 1.
Part A: The relationship between the temperature of the city and the sale of sweaters in the city can be found by drawing the line of best fit.
If you will draw line through , (12.5,6) and (15,4), it will best represent line of best fit, because most of points on same and opposite side of line are equidistant from each other.
Equation of line passing through two points,[tex](x_{1},y_{1}),(x_{2},y_{2})is, \frac{y-y_{1} }{x-x_{1} } = \frac({y_{2} - y_{1}})({x_{2}-x{1} })[/tex]
Equation of line passing through (12.5,6) and (15,4) is given by
[tex]\frac{y-6}{x-12.5} = \frac{6-4}{12.5-15}[/tex]
[tex]2x-25=-2.5+15[/tex]
[tex]2x+2.5y=40[/tex]
[tex]20x+25y= 400[/tex]
[tex]4x+5y=80[/tex]
Part B: Description of line of best fit
A line of best is the line which passes through all or some points or only through a single point, which describes the relationship between x and y values of data set. The line passes through (12.5,6), (15,4),and (7,10) that is three points.
(C) 4 x + 5 y=80
5 y= - 4 x +80
[tex]y=\frac{-4x}{5}+16[/tex]
Slope [tex]= \frac{-4}{5}[/tex], Y- intercept = 16

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.

Hallar x + y
Es de geoemtria, angulos
Answer:
1). x = 40
2). y = 20
Step-by-step explanation:
1). "4x" y "160" son ángulos de vértice, por lo que son congruentes entre sí. Entonces, "4x = 160" y luego usa álgebra para resolver "x" y "x = 40".
2). "Y" y "4x" son ángulos suplementarios, por lo que si ambos se suman, forman un ángulo de 180. Entonces, "Y + 4 (40) = 180", usando álgebra daría la respuesta "Y = 20".

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.

Select the perfect square.
23 x 23
924 x 429
18 x 19
Answer:
23 × 23
Reasoning:
A prefect square is a number times itself
The product of the perfect square can therefore be a sqaure root
23 × 23= 529
Then if we square root 529 it would always be a whole number (23)
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.
