Answer:

142 in²

Step-by-step explanation:

We want to find the area of all the rectangles and add them up.

For the 2 small rectangles on the side, the area is 15 in for each of them because 5x3. The 2 thinner rectangles each have an area of 21 in because 7x3. The 2 largest rectangles each have an area of 35 in because 5x7.

Now we can add it all up.

15+15+21+21+35+35=30+42+70=142

15 Points!! Please help and explain how to solve them!! I really want to understand it

babymother [125]

1) idk I got none of your options
2)p=42,000÷(1+0.0225÷12)^(12×5)
P=37,535.04
3)PVAO=4900*12[(1/0.029)-(1/0.029*(1+0.029)^10]=504145.41..compare with 500000
So the answer is D
4)lucas
90×87.92=7,912.8
((8,476.20−7,912.8)
÷7,912.8)×100=7.1%
Peton
55×72.03=3,961.65
((4,192.10−3,961.65)
÷3,961.65)×100=5.8%
So the answer is D

Answer:

B. False, they could be vertical angles

Step-by-step explanation:

Supplementary just mean when two angles form 180° (a straight line).

So ∠F and ∠G must form a straight line, and ∠G and ∠H must form a a straight line.

I drew the image out below and as you can see, angle F and H forms a vertical angle. A vertical angles is when two lines cross, the opposite angles from each others are called vertical angles.
