Answer:
total population in the year 2000=4400
total population in the year 2010=5060
no of people increased=5060-4400
=660
increase percent=660/4400*100%
=3/20*100%
=15%
Step-by-step explanation:
15/100*5060
0.15*5060
759
in 2020 population will be
5060+759
5819
therefore the population will be 5819 in 2020
I believe I answered your other question like this.
Just write the equation like:
x^2 - 3/4 x - 5 and follow the same process that I listed out before
Answer:
72
<em>s1</em><em> </em><em>:</em><em>s2</em><em> </em><em>=</em><em> </em><em>A1</em><em> </em><em>:</em><em> </em><em>A2^</em><em>2</em>
<em>So</em><em> </em><em>the</em><em> </em><em>factor</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>sides</em><em> </em><em>is</em><em> </em><em>2</em><em>.</em><em> </em><em>Now</em><em> </em><em>you</em><em> </em><em>multiply</em><em> </em><em>the</em><em> </em><em>area</em><em> </em><em>by</em><em> </em><em>2</em><em> </em><em>squared</em><em>.</em>
Looks like D to me but i could be wrong. Did you try image reversing?
Answer:
d. 9x + 63 and 63 square feet
Step-by-step explanation:
Given
Original
Extended
Required
Determine an expression and the value of the extended area
First, we calculate the area of the original desk
From the given parameters, we have:
--- area of the new surface
Open bracket
The area of the new surface is the summation of the area of the original desk and the area of the extended portion (E)
So:
Make E the subject
Hence, the area of the extended portion is 63
