Answer: 76.4
Step-by-step explanation:
Move the decimal over one
Answer:
Step-by-step explanation:
To figure this out, we must use the scale of the map as a unit.
So we first figure out how many meters are for each centimeter on the map.
" Two fields at a state park are fields are 8 centimeters ap(?)ta state park are 1,000 meters from each other."
<u>Set up the ratio:</u>
<u>Cross multiply:</u>
=
<u>Meaning:</u>
1000/8
==> 125
x = 125
Meaning that for every centimeter there is 125 meters
1cm = 125m

was i support to simplify? bc that's what i did
Step 1:
<span>Calculate the effective thermal conductivity of the wall or ceiling:
</span>
K_eff = [ (13 ÷ 8)(0.12) + (16 - (13 ÷ 8)) × (0.04)] ÷ 16
K_eff =<span> [ 0.195 + 0.565] </span>÷<span> 16
</span>
K_eff = 0.76 ÷ 16
K_eff = 0.0475 W/ (m K)
Step 2:
Calculate <span>the interior ceiling area:
</span>Area of each of the interior side walls = <span>8.82 m x 8.64 m
= 76.2 m</span>²
Area of the interior ceiling = 8.64 m × <span>8.64 m
</span> = 74.6 m²
H = - k·A·(Δ - T) ÷ <span>(thickness)
</span>
H = - 0.0475 ÷ (379.45 × 20) ÷ 45/8
H = - ( - 0.95 × 379.45 ) ÷<span> 0.1429
</span>
H = <span>2.52 kW </span>
