Answer:
11,448 in²
Step-by-step explanation:
The area can be computed from ...
... A = 2(LW +H(L+W))
For the given prism, the area will be ...
... A = 2(18·12 +14(18+12)) = 2(216 +420) = 1272 . . . . in²
The area of a similar figure with dimensions 3 times as long will be 3² times as much. The area of the new figure is ...
... A = 3²×(1272 in²) = 11,448 in²
Jess rode 4.25 km in 20 min.
Speed = 4.25: 20 = 0.212 km/min
Corey rode 3.75 km in 18 min.
S= 3.75 : 18= 0.208
Mia rode 3.5 km in 17 min.
S = 3.5 :17 = 0.205
Zoey rode 3.6 km in 16 min.
S= 3.6 :16 = 0.225
The greatest rate of speed : ZOE with 0.225 km/min
Y = m + 3
you have to count the ones in between and add the 3 to fill in for b
Answer:
x = 125°
Step-by-step explanation:
The sum of the angles around a point = 360° , then
90 + 145 + x = 360°
235° + x = 360° ( subtract 235° from both sides )
x = 125°
that seems a little, much...
but it would be 149 or 5130
