<u>Answer-</u>

<em>14,202</em><em> newspapers will be sold in 2030.</em>

<u>Solution-</u>

In 2015 the amount of newspaper sold was 25,000 and the number is expected to decline at a rate of 3.7% each year.

Taking,

x = number of years after 2015,

y = amount of newspaper sold.

A decay function of x and y can be obtained as follows,

\Rightarrow y=25000(1-\frac{3.7}{100})^x =25000(96.3)^x

Putting the value of x = 15 (as 2030-2015), we can get the value of y or the number of newspaper sold,

\Rightarrow y=25000(96.3)^{15}=14201.503\approx 14,202

Geometry : A trapezoid has angles that measures 3x°,3x°,x° and x°, what is the value of x?​
prohojiy [21]

Answer:

Step-by-step explanation:

Any 4 sided figure closed and convex, has interior angles that add to 360 degrees

x + x + 3x + 3x = 360   Combine all like terms on the left.

8x = 360                       Divide both sides by 8

8x/8 = 360/8

x = 45

The value of x is 45.

Answer: In my answer I got 9 because the formula to find the area it would be A=1/2b*h



Step-by-step explanation: How would you do this?

Well we know that the base equals 6 we have heighth so we would have to do 1.5*6 and that would give us 9 but if we round it would be 10 because 9 is closer to 10 than it is to 0.


thanks :)
