About 60,000 acres of wetlands are lost each year in the United states. What integer represents the change in wetlands after 4 y

QveST [7]

Over 4 years, there will be a loss of 60,000 acres per year, so 60,000 times 4 is equal to 240,000 acres. 240,000 is positive because the problem asks for the change, not the increase.

This is the work you will show

c=-60,000(4)

c=-240,000

So -240,000 represents the change.

You could also just count by -60,000 four times.

-60,000-60,000-60,000-60,000=-240,000.

What is the sum of the first 35 terms in the series 7+9+11+

Temka [501]

In below formula for arithmetic sequence you can fill in a=7 (start), d=2 (interval) and n=35 (nr terms) and you get

17.5(14 + 34*2) = 1435

Confirmed by a brute-force addition: 7+9+11+13+15+17+19+21+23+25+27+29+31+33+35+37+39+41+43+45+47+49+51+53+55+57+59+61+63+65+67+69+71+73+75=1435

Find the distance between the pair of points<br><br> (0,0)(6,8)

Ivahew [28]

A(0,0)
B=(6,8)

Distance formula

$\boxed{\sf AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$

$\\ \sf\longmapsto \sqrt{(6 - 0) {}^{2} + {(8 - 0)}^{2} } \\ \\ \sf\longmapsto \sqrt{ {6}^{2} + {8}^{2} } \\ \\ \sf\longmapsto \sqrt{36 + 64 } \\ \\ \sf\longmapsto \sqrt{100} \\ \\ \sf\longmapsto 10$
