x+47=90

x=43

----------------

y+x=90

put in 43 for x

y+43=90

y=47

Hope that helps :)

Answer:

X=43

y=47

Step-by-step explanation:

Well you have 47 degrees. Finding X first would be easier.

X and 47 are complementary (90 degreees) so you can subtract 47 from 90 and get “x” Which is 43.

Now for y.

Y and X is complementary also, which means since x is 43, 90-43 is 47. So y is 47.

The figure is the net for a rectangular prism.

What is the surface area of the rectangular prism represented by the net?

please help
TωT

Answers

Answer:

544 cm^2

Step-by-step explanation:

You can see that the figure is made of 6 different rectangles, which would become the sides of the prism if it was 3D.

The top rectangle has a length of 16 cm and a width of 8 cm. 16 x 8 = 128 so this side has an area of 128 square cm

The one directly below that has the same length (16 cm) and a width of 6 cm. 16 x 6 = 96 so its area is 96 square cm

On either side of the previous one there is a 6 by 8 rectangle. 6 x 8 = 48. Remember, there are two sides with an area of 48 cm^2

Below that we have another 16 by 8 rectangle and then another 16 by 6 rectangle.

So your total surface area would be 128 + 96 + 48 +48 + 128 + 96

or 544 square cm

In one paragraph, using your own words, describe a commercial you have seen recently and tell what the commercial was selling and what the hidden message was in it.

Answers

Answer:

A commercial I have seen recently was the Grub Hub commercial. The commercial was advertising all the types of food you could possibly buy with Grub Hub. It seems their point in this commercial was to bring consumers (people who buy the food) in and purchase their food using the Grub Hub app. Grub Hub did this by making jokes and trying to be funny with the commercial. The people in the commercial were dancing and smirking while they smacked on the "delicious" food and apparently the food was so good and tasty that even a PREGNANT woman did the splits. So basically it was not a normal commercial it was... really special. The hidden message was that it's "better" than Uber.

A rectangle has an area of 24 square inches. The rectangle is reduced by a scale factor of 1/2 . What is the area of the new rectangle?

Answers

Considering the scale factor of the reduction, it is found that the area of the new rectangle is of 6 square inches.

What is the area of a rectangle?

The area of a rectangle of length l and width w is given by:

[tex]A = lw[/tex]

In this problem, the rectangle is reduced by a scale factor of 1/2, hence:

[tex]l \rightarrow \frac{l}{2}, w \rightarrow \frac{w}{2}[/tex]

Then, the area is given by:

[tex]A = lw = \frac{l}{2} \times \frac{w}{2} = \frac{lw}{4}[/tex]

A rectangle has an area of 24 square inches, hence:

[tex]lw = 24[/tex]

Thus:

[tex]A = \frac{lw}{4} = \frac{24}{4} = 6[/tex]

The area of the new rectangle is of 6 square inches.
