Step-by-step explanation:
10 times y is less than 9 times x
The ratio that's given indicates that the length of the actual wall will be 49 feet.
<h3>How to calculate the ratio</h3>
From the information given, the blueprint shows a layout of a building and for every 4 inches in the blueprint represents 7 feet of the actual building.
Therefore, the length of the actual wall will be:
= 7/4 × 28
= 49
In conclusion, the correct option is 49 feet.

1000 x 8% = 80
so you would get 80 dollars extra a year times 10 years
80 x 10 = 800
1000 + 800 = $1800
so at the end of the ten years you will have $1800
Answer:
2H2S (g) + 3O2 (g) → 2H2O (l) + 2SO2 (g)
Calculate ΔH° from the given data. Is the reaction exothermic or endothermic?
ΔH°f (H2S) = -20.15 kJ/mol; ΔH°f (O2) = 0 kJ/, mol; ΔH°f (H2O) = -285.8 kJ/mol; ΔH°f (SO2) = -296.4 kJ/mol
