Answer:
160 in ^2
Step-by-step explanation:
First we need to find the area of each shape and add them together
1. Triangles:
The formula for a triangle is (base x height)/2, so we can replace them as (5 * 4)/2 * 2( Because there are two triangles), so therefore the two triangles will add up to 20 inches
2. The Rectangles
The Big Rectangle:
The big rectangle is just l x w or 5 * 20 which is 100
The small rectangle:
To find the width of the small rectangle you have to do 20 - (5 + 5) because we are not including the triangles. 20 - (5 + 5) = 10, so that would be 10 * 4 = 40.
3.Add them together
20 + 100 + 40 = 160 inches ^2

what is the equation for of the line that passes through the point (2,-4) and has a slope of -2
Answer:
y = -2x
Step-by-step explanation:
The equation of the line is y = -2x. Use the form y = mx + b and substitution to find your answer.
The problem already gave you the slope, and m represents the slope.
y = -2x + b
The problem also gave you one point. Substitute the x and y values of that point into the equation.
Point: (2, -4)
-4 = -4 + b
b = 0
Using basic algebra, we found that there is no b value. b equals 0. So all we have to write is y = -2x.
Answer:
y = - 2x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute (2, - 4) into the partial equation
- 4 = - 4 + c ⇒ c = - 4 + 4 = 0
y = - 2x ← equation of line

A person hikes 4 miles in 2.5 hours. Find the unit rate in miles per hour.
Then find the unit rate in hours per mile.
ALSO EXPLAIN
10points
Answer:
1.6 miles per hour
Step-by-step explanation:
Step one:
The unit rate is the number of miles in 1 hour
given
distance= 4 miles
time= 2.5 hours
so if he hike 4 miles in 2.5 hours
then he will hike x mile in 1 hour
cross multiply we have
x=4/2.5
x=1.6 miles per hours
Therefore the unit rate is 1.6 miles per hour

The orbit of a planet around its star is an ellipse, with the star at one focus. The apoapsis of a planet is its greatest distance from the star, and the periapsis is its shortest distance. Its mean distance is the length of the semimajor axis. The mean distance from a planet to its star is93 million miles. If the apoapsis of the planet is98 million miles, what is the periapsis? Write an equation for the orbit of the planet around the star.The periapsis is ____million miles.
Solution :
Let the center be (0,0)
Now from the diagram given below ,
The major axis = periapsis + apoapsis
2 x semi major axis = periapsis + 98
2 x 93 = 98 + periapsis
Therefore, periapsis = 186 - 98
= 88 million miles
Star coordinate = (93-98, 0)
= (-5,0)
Let the minor axis be 2b
For ellipse [tex]$c^2 = a^2 - b^2$[/tex]
[tex]$(-5)^2 = (-93)^2 - b^2$[/tex]
[tex]$b^2=8624$[/tex]
[tex]$b=\sqrt{8624}$[/tex]
Now, equation of the ellipse
[tex]$\frac{x^2}{(93)^2}+\frac{y^2}{(\sqrt{8624})^2}=1$[/tex]
[tex]$\frac{x^2}{(93)^2}+\frac{y^2}{8624}=1$[/tex]
The equation for the orbit of the planet around the star is;
(x²/93²) + (y²/(√8624)²) = 1
The length of the periapsis of the given planet is;
88 million miles
We are told the orbit around its' star is an ellipse.
We are told that apoapsis of a planet is its greatest distance from the star, and the periapsis is its shortest distance. Thus;
major axis = periapsis + apoapsis
Now, we are told that; the apoapsis of the planet 98 million miles.
Also, that The mean distance from a planet to its star is 93 million miles.
Thus, major axis/2 = 93
Thus, major axis = 93 × 2
Major axis = 186 million miles
Thus;
186 = periapsis + 98
periapsis = 186 - 98
periapsis = 88 million miles
To get the equation of the orbit of the planet around the star, lets first find the focus coordinate.
We know it's y-coordinate will be zero since its the focus but it's x-coordinate will be; 93 - 98 = -5
Thus; star coordinate = (-5, 0)
As we are dealing with ellipse, we have gotten;
a = 93 and c = -5
Thus; b = √(a² - c²)
b = √(93² - (-5)²)
b = √8624
Formula for equation of the ellipse is;
(x²/a²) + (y²/b²) = 1
Thus, we have;
(x²/93²) + (y²/(√8624)²) = 1

El kilo de pollo en als últimas semanas se incrementó en un 13% o sea aumento de 3.20
Answer:
El kilo de pollo aumentó de $3.20 a $3.61.
Step-by-step explanation:
Si el kilo de pollo se incremento en un 13% en las últimas semanas, pasando de $3.20 a un valor mayor, para determinar dicho valor se debe realizar el siguiente cálculo:
AUMENTO + VALOR INICIAL = VALOR DEL POLLO CON AUMENTO
(3.20 x 13 / 100) + 3.20 = VALOR DEL POLLO CON AUMENTO
(41.6 / 100) + 3.20 = X
0.41 + 3.20 = X
3.61 = X
Por lo tanto, el kilo de pollo aumentó de $3.20 a $3.61 en las últimas semanas.

14. Point P has the coordinates (-2,-4). Point P is dilated with a center at the origin and
a scale factor of 3 to create Point P'.
What are the coordinates of Point P'?
Answer:
Step-by-step explanation:
The answer is b (1,-1)
If a point P is dilated about the origin, coordinates of the image point will be P'(-6, -12).
Rule of the transformation (Dilation):If a point P(x, y) is dilated by a scale factor 'k' about the origin, image point P' will be given by,
P(x, y) → P'(kx, ky)
Given in the question,
Coordinates of point P → (-2, -4)Point P is dilated by a scale factor '3' about the origin to form the image point P'.After the dilation of point P, coordinates of the image point P' will be,
P(-2, -4) → P'(-2×3, -4×3)
→ P'(-6, -12)
Therefore, after dilation of point P about the origin, coordinates of the image point will be P'(-6, -12).

Arisia puts $500.00 into a savings account with an annual simple interest rate of 4.5%. If the interest stayed the same, how much interest would arisia's account earn after 15years?
Answer:
$112.5Step-by-step explanation:
Step one:
given data
principal= $500
rate= 4.5= 0.045
time t= 5years
Step two:
the expression for the simple interest is given as
A=P(1+rt)
the interest SI= final amount (A)- Principal(P)
Substituting we have
A=500(1+0.045*5)
A=500(1+0.225)
A=500(1.225)
A=612.5
the interest is 612.5-500
