Answer:
1. The distances are accurate.
2. 57 miles
Step-by-step explanation:
<u>Quiz 1 solution</u>
1 mile = 1.60934 km
10 miles will be;
10 × 1.60934 = 16.0934 km
Distance on the sign is 16 km.
The distance is accurate since 16.0934 km rounded up to nearest kilometre is equal to 16 km.
13 miles will be;
13 × 1.60934 = 20.92142 km
The distance on the sign is 21 km
This distance is accurate since 20.92142 km rounded up to nearest kilometre equals 21 km
55 miles will be;
55 × 1.60934 = 88.5137 km
The distance on the sign is 89 km
The distance is accurate since 88.5137 km rounded up to nearest kilometre is 89 km.
<u>Quiz 2 solution</u>
1 km = 0.621371 miles
92 km will be;
92 × 0.621371 = 57.166132 miles
Rounding up the answer to nearest mile gives 57 miles.
Answer:
Volume of the box = 7/2 × 4/3 × 9/4
= 10.5 ft
B. Volume of a box cannot be negative because volume is a scalar quantity and has no direction hence it cannot be expressed in negative values.

Answer:
Transitive property of equality is not a justification for the proof.
Step-by-step explanation:
We draw a right angle ΔACB. CD is perpendicular to AB.
Let AC = a , BC = b , AB = c and CD = h
Now in ΔABC and ΔACD
∠C = ∠D and ∠A = ∠A
from AA similarity postulate
ΔABC similar to ΔACD.
Hence,
=
= c × x ·····················(1)
Now in ΔABC and ΔCBD
∠C = ∠D and ∠B = ∠B
from AA similarity postulates
ΔABC similar to ΔCBD
Hence,
= c × y······················(2)
Add equation (1) and (2)
+ = cx + cy
+ = c(x+y)
+ = [because x+y=c]
Transitive property is not useful for this proof.
