I NEED HELP REALLY FAST PLEASE! Find the measure of the missing angles.

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.

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.

As the group added partners, they expanded from its initial one location to the present four satellite locations over the past ten years. The next phase of focusing on access was an after-hours clinic option that rotated one night each week across each location. This approach allowed the physicians as well as the staff to have some quality-of-life balance but still service patient needs. In the past year, the group also followed that approach with weekend hours. Some of the younger partners in the group have increasingly suggested that while these approaches have been beneficial in todays marketplace, they are insufficient for the market in response to customer expectations. A core number of the physicians have suggested that it is a two-fold challenge of not only leakage but not even knowing where patients are going for after-hour care. The group has a strong brand name and has 42 primary care physicians and 15 nurse practitioners.
