I added a screenshot with the complete question

Answer:
x = 3
y = 9

Explanation:
1- getting the value of x:
We are given that:
side AB is congruent to side DF. This means that:
AB = DF
3(2x+10) = 12x + 12
6x + 30 = 12x + 12
12x - 6x = 30 - 12
6x = 18
x = 18/6
x = 3

2- getting the value of y:
We are given that:
side BC is congruent to side FG. This means that:
BC = FG
2y + 12 = 2(2y-3)
2y + 12 = 4y - 6
4y - 2y = 12 + 6
2y = 18
y = 18/2
y = 9

Hope this helps :)

Find the length of each arc. Round to the nearest tenth.

avanturin [10]

Answer:

arc ≈ 5.5 units

Step-by-step explanation:

The arc of the circle is calculated as

arc = circumference of circle × fraction of circle

= 2πr × $\frac{\frac{\pi }{2} }{2\pi }$ ( r is the radius )

= 2π × 3.5 × $\frac{1}{4}$

= $\frac{7\pi }{4}$

≈ 5.5 ( to the nearest tenth )

Solar panels are arrays of photovoltaic cells that convert solar radiation into electricity. the table shows the annual percent

jeyben [28]

I think the largest time interval over which the actual price per watt of a solar panel was an increasing function of time is : 2004 to 2006

As it gives data %growth over previous year

from 2003 to 2004 it was -5.7% but from 2004 to 2005 6.7 % from 2005 to 2006 it is 97 % and from there it once again decline

hope this helps

olga55 [171]

Answer:

-233/40

Step-by-step explanation:

5/8 + 1/4 - 2(3/4 + 13/5)

5/8 + 2/8 - 6/4 + 26/5

7/8 - 30/20 + 104/20

7/8 - 134/20

35/40 - 268/40

-233/40
