The roof of the building shown below has a span of 48 feet. The rafters upon which the roof is laid are 30 feet long, including

anyanavicka [17]

Solution :

Given :

Span of the roof = 48 feet

Length of the rafter = 30 feet (including the 4 feet overhung)

So, for the 30 feet long rafter, 26 feet will be rafter length from the high point of the roof to the edge of the roof and 4 feet will be the roof overhung.

Therefore, the horizontal span per rafter is

$=\frac{48}{2}$

= 24 feet

a). So the rise of the roof is $= \sqrt{(26)^2-(24)^2}$

= 10 feet

b). Pinch of the roof is $=\frac{\text{rise}}{\text{run}}$

$=\frac{10}{24}$

$=\frac{5}{12}$

c). The percent of the roof used as overhung is

$=\frac{4+4}{60}\times 100$

$=\frac{80}{6}$

= 13.33 %

A Mexican restaurant received 60 time-out orders. The manager found that 60% of the orders were for tacos and 25% of the orders

ICE Princess25 [194]

Take the percentage of each order.
0.6 x 60 =36 orders
0.25 x 60 = 15 orders
Take the sum of the orders and deduct it from the total order
60 - 51 = X
X = 9
9 represents the orders for other items. Divide 9 by 60 to get its percentage
( 9 /60 ) * 100 = 15% This is the percentage for other items.
