2. A 7 storey apartment building is in the shape of a prism. The total footprint of the building’s ground floor is 9850 ft2.
a. Assuming the building is 70ft high, what is the total volume of the building?
b. Building codes require the total volume of air inside to be exchanged at least once per
day. Assuming that there are three air exchangers, what is their minimum exchange
rate (cubic feet per hour) in order to be code compliant?

x = 25/2304

step-by-step explanation:

a. -0.3 > -0.33

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
