Answer:
PQ=36
Step-by-step explanation:
o=114
PQ I named a because it was easier for me and SP I named b.
o=2(a+b)
114=2(3x+3+2x-1)
114=6x+6+4x-2
114=10x+4
10x=114-4
10x=110/:10
x=11
a=3*11+3
a=33+3
a=36
Answer:
Look at the pics
Step-by-step explanation:
Hey, so when I was solving this I accidentally numbered the exercises differently than in your pic....
I just went from the left row to the right (and missed two...)
Hope it doesn't confuse you :]
If you have any questions about the way I solved it, don't hesitate to ask me =)
Answer:
Yes, you did.

Answer:
TAS = 43.99 m²
Step-by-step explanation:
- TSA = total surface area
- Area of a trapezoid = (1/2)(a + b)h
(where a and b are the parallel sides and h is the height) - Area of a rectangle = width x length
This prism is made up of 4 rectangles and 2 congruent trapezoids.
Area of trapezoid = (1/2) x (1.4 + 2.3) x 1.9 = 3.515 m²
⇒ area of 2 trapezoids = 3.515 x 2 = 7.03 m²
Area of base rectangle = 2.3 x 4.8 = 11.04 m²
Area of top rectangle = 1.4 x 4.8 = 6.72 m²
Area of back rectangle = 1.9 x 4.8 = 9.12 m²
Area of sloped rectangle = 2.1 x 4.8 = 10.08 m²
Total surface area = 7.03 + 11.04 + 6.72 + 9.12 + 10.08 = 43.99 m²
Answer:
a) 1.8
b) 11.8
c) 23.6
<h3>a)</h3>
(2.4 + 1.6 + 3.2 + 0.3 + 1.5) / 5 = 1.8
<h3>b)</h3>
(12.4 + 11.6 + 13.2 + 10.3 + 11.5) = 11.8
<h3>c)</h3>
(24.8 + 23.2 + 26.4 + 20.6 + 23) / 5 = 23.6
or,
11.8 × 2 = 23.6
