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.

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.

Expand and simplify these 6 questions
first one: 2(1x + 3) - 5
second one: 3(1x + 7) + 3x
third one: 4(1x + 2) + 8
fourth one: 4(1x + 1) - 6
fifth one: 2(3x + 2) - 5x
sixth one: 5(1x - 4) + 10

Answers

First one: divide multiply 2(1x) which would equal 2x then do 2*3 then u would subtract 5 which should get you to the simplified form 2x+1

Second one: do 3(1x) which would equal 3x then do 7*3 which would equal 21 than do plus 3x which should get you to the simplified form of 6x+21

Third one: Do 4(1x) which equals 4x than do 4*2 which equals 8 than plus eight which should get you to the simplest form of 4x+16

Fourth one: do 4(1x) which would equal 4x then do 4*1 which equals 4 than subtract 6 which should get you to the simplest form of 4x-2

Fifth one: do 2(3x) which equals 6x then do 2*2 which equals 4 than subtract 5x which should get you to the simplest form of x+4

Sixth one: do 5(1x) which equals 5x than do 5*-4 which equals -20 than add 10 which gets you to the simplest form of 5x-10

Answers

Step-by-step explanation:

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.
