Find the area of the shape, show work pls ill give brainiest
andre [41]

Answer:

6.2

Step-by-step explanation:

Although there's multiple ways to solve this problem, my method will be to simply find the area for the full triangle (the empty + orange triangles) and subtract the area of the smaller, empty triangle.

Now, you that area for a triangle is 1/2*base*height.

To find the measurements for the full triangle, you must add up the bases for the two smaller triangles:

Base_{total}  = Base_{empty} + Base_{orange}  \\Base_{total} = 1.9ft + 3.1 ft\\Base_{total} = 5 ft

Height is the same for both triangles so Height total = 4 ft.

Now the total area can be calculated:

Area total= 1/2* base_total * height_total

Area total = 1/2 * 5ft * 4 ft  

Area total = 20 / 2 = 10 ft squared

Lastly, subtract the area of the empty triangle from the total triangle to find the orange triangle.

Area Empty Triangle = 1/2 * base_empty * height_empty

Area Empty Triangle = 1/2 * 1.9ft * 4 ft = 7.6 ft / 2 = 3.8 ft squared

Area total - Area empty = 10ft^2 - 3.8ft^2 = 6.2 ft squared

kap26 [50]

Answer: second option

Step-by-step explanation:

To find the inverse function of the given function f(x):

f(x)=2x

You need to:

Substitute f(x)=y into the function:

 y=2x

Now, you need  to solve for "x", to do this, you must divide both sides of the function by 2:

\frac{y}{2}=\frac{2x}{2}\\\\\frac{y}{2}=x

Now, replace "x" with "y" and replace "y" with "x":

\frac{x}{2}=y

Therefore, substituting y=f^{-1}(x) you get:

f^{-1}(x)=\frac{x}{2} or  f^{-1}(x)=\frac{1}{2}x

Favian received a $100 gift card to a clothing store.
IgorLugansk [536]

Answer:

32n = 100 - 20

n = 2.5

he purchased 2 sweaters

Step-by-step explanation:

32n = 100 - 20

If Favian originally had $100 but spent $20 on a belt, he only had 80 left, meaning that 80 = 32n which means that he was able to but 2 sweaters and got $16 back. Therefore the formula would be 32n = 100 - 20
