Answer:
247 yd²
Step-by-step explanation:
this figure can be "split" into 3 sub-figures.
2 rectangles and one triangle "at the top".
these 3 areas can be easily calculated, and the we simply sum them all up, and that is the total area.
my approach is to pick the first rectangle to be the one extruding one to the right.
R1 = 11×5 = 55 yd²
the second rectangle is then the rest of the"straight" area up to the beginning of the triangle top
R2 = 8 × (13+5) = 8×18 = 144 yd²
and the area of a triangle is
baseline × height / 2
we can clearly see in our example, it is a right-angled triangle, so the left side is also the height, which is the remainder of the long side of the original figure, when we deduct all the other parts we used for the rectangles.
so, we have
T = 8 × (30 - 5 - 13) / 2 = 8×12/2 = 8×6 = 48 yd²
so, in total we have
F = 55 + 144 + 48 = 247 yd²

Answer:
( x, y ) = ( 4, 1/3)
Step-by-step explanation:
x - 3y = 3
2x +9y = 11
1. substitute the value of x
x= 3 + 3y
2x + 9y = 11
2. solve equation
2 (3 + 3y) +9y = 11
3. substitute the value of y
y = 1/3
4. solve equation
x = 3 + 3 x 1/3
x = 4
5. check solution
(x, y) = ( 4, 1/3 )
check x ----> 4 - 3 x 1/3 = 3
check y ------> 2 x 4 + 9 x 1/3 = 11
for x----> 3=3
for y----> 11=11
Answer:
2) 476.637
7) 2.2 and 2.20
8) 8.10 and 8.100
9) 9.5 and 9.500
10) 4.2 and 4.20
Step-by-step explanation:
2) First, solve 1/10 1/100, and 1/1000. That would be 0.1, 0.01, and 0.001.
Then, add all the numbers up. Do multiplication first. 4 x 100 = 400. Your answer would be 400 + 70 + 6 + 0.6 + 0.03 + 0.007. Add the big numbers. 476 + 0.637.
7) 2.2 and 2.20. It doesn't change the value no matter how many 0's you put.
8) 8.10 and 8.100
It doesn't change the value no matter how many 0's you put.
9) 9.5 and 9.500
It doesn't change the value no matter how many 0's you put.
10) 4.2 and 4.20
It doesn't change the value no matter how many 0's you put.
