ss7ja [257]

Answer:

(i)= 45 KPH, (ii) = 251 miles

Step-by-step explanation:

'Per' essentially means divide. Thus, to find Kilometres per hour, divide 270 by 6= 45. The bus is travelling at 45 KPH.

Then, to see how far a nine hour trip would cover, distance = speed * time =  251 miles.

The two angles marked are congruent.
That is one pair of congruent angles.   ------->    A
Then the vertical angles are congruent.

A billboard is 2.5 times as long as it is wide.The area of the billboard is 2,250 ft.A scale drawing is made of the billboard,an
GaryK [48]
Width = w
Length = 2.5w

Area of Rectangle: Width × Length
w (2.5w) = 2250
2.5w^2 = 2250
w^2 = 2250/2.5 = 900
w = Sq rt of 900 = 30
l = 75

Ratio of inches to ft
x/30 = 160/2250
cross multiply: 2250x = 160 × 30
2250x = 4800
x = 4800/2250 = 2.13333...

length
x/75=160/2250
2250x = 75(160)
2250x = 12,000
x= 12,000/2250
x = 5.3333...

scale is 2.13" × 5.33"
