You go to the mall to make some purchases. You buy 3 dresses which cost $59.99 each and a pair of shoes that cost $75. What is t

mina [271]

Combine costs
59.99(3) + 75 = 179.97 + 75
179.97 + 75 = $254.99 (total cost)
Now add tax: 8% = 0.08
254.99 * 0.08 = 20.3992
254.99 + 20.3992 = 275.3892

Solution: bill would be around $275

Someone help me please

Masteriza [31]

Answer:

$(5,1)$

Step-by-step explanation:

Hi there!

Midpoint = $\displaystyle (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$ where the two endpoints are $(x_1,y_1)$ and $(x_2,y_2)$

Plug in the given information:

Midpoint = (5,3), Endpoint = (5,5)

$(5,3)=\displaystyle (\frac{5+x_2}{2},\frac{5+y_2}{2} )$ where $(x_2,y_2)$ is the other endpoint

Solve for $x_2$ :

$\displaystyle \frac{5+x_2}{2} =5\\\\5+x_2 =10\\x_2 =5$

Solve for $y_2$ :

$\displaystyle\frac{5+y_2}{2}=3 \\\\{5+y_2}=6\\y_2=1$

Therefore, the other endpoint $(x_2,y_2)$ is $(5,1)$ .

I hope this helps!

Can somebody help me find the surface area of this

-Dominant- [34]

Answer:

G. 7600 $cm^{2}$

Step-by-step explanation:

Step 1: Deconstruct the shape

2 rectangles with dimension of 50 cm x 20 cm

2 rectangles with dimension of 40 cm x 20 cm

2 rectangles with dimension of 40 cm x 50 cm

Step 2: Find surface area of the shapes

2(50 x 20) = 2000 $cm^{2}$

2(40 x 20) = 1600 $cm^{2}$

2(40 x 50) = 4000 $cm^{2}$

Step 3: Add the surface areas together

2000 + 1600 + 4000 = 7600 $cm^{2}$

Therefore the surface area is 7600 $cm^{2}$ and the answer is G.
