Answer:

Step 1 :

Split the figure into 3 parts

part 1: triangle with base = 7 + 2 + 6 = 15in, height = 7in

part 2 : Rectangle with breadth = 3 + 6 + 2= 11in and length 8in

Part 3 :Rectangle with breadth 2in  and length 9in

Step 2 :

find the area of each part

Area of part 1

             \frac{1}{2}  * base * height = \frac{1}{2}*15*7 = 52.5in^{2}

Area of part 2

             length * breadth = 11*8 =88in^{2}

Area of part 3

              length * breadth = 2*9 =18in^2

Total area = 52.5 + 88 + 18 = 158.5 sqaure inches

Answer:

Step-by-step explanation:

Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees. Examples: • 60° and 120° are supplementary angles.

Students sold 300 tickets for a playoff game in basketball at school. Some tickets are for students and cost $4.00, while the re
Neko [114]
So baically

reresent
s=number of studne tickes bouthgt
a=number of adult tickets bought

300 tickest sold
total=300
a+s=300


value=rate times number of peple

student value=4s
adults value=10a
total value=1950
4s+10a=1950



a. system of equations are
s+a=300
4s+10a=1950



b. solve

s+a=300
4s+10a=1950

a+s=300
multiply by -4
-4s-4a=-1200
add to other eqaution

4s+10a=1950
<u>-4s-4a=-1200  + </u>
0s+6a=750

6a=750
divide 6
a=125


subsiute
s+a=300
s+125=300
subtract 125
s=175






a. s+a=300
4s+10a=1950

b. solution above

Help with 3 show work please
schepotkina [342]
Alright assuming they mean total surface area since they didn't say lateral the equation to follow would be S= Ph + 2B

Start with P:
P stands for perimeter, so add up all the edges on one face of the cube.


17 + 17 + 17 + 17 = 68
Then your equation becomes
S= 68×h + 2B
h=height and that's obviously 17
so, S= 68×17 +2B

Now to find B. This is pretty easy. All you need to do is take 17×17 because you're finding the area of the base. This equals 289.

Finally this leaves us with the equation
S= 68×17+2×289

From there on you just solve it out.
This would leave you with 1734.
