A is the answer i think :)
Answer:
it is per 1
Step-by-step explanation:
Answer:
1) Option (b) 32km
2) Option (c) 17
Step-by-step explanation:
According to Pythagoras Theorem,
Hypotenuse²=Perpendicular²+Base²
H²=P²+B²
1) Perpendicular=?
Base=24km
Hypotenuse=40km
40²=P²+24²
1600=P²+576
1600-576=P²
1024=P²
√1024=P
32=P
2) Perpendicular=15
Base=8
Hypotenuse=?
H²=15²+8²
H²=225+64
H²=289
H=√289
H=17
Answer:
D. 4
Step-by-step explanation:
We know that the square of (+4) is 16 and also for (—4) is 16. We normally takes interest in positive square value for a square root. Therefore, The principal square root of 16 is 4
Answer:
Step-by-step explanation:
a. 29/8 + 2(19/4) + 3(27/8) = 29/8 + 38/4 + 81/8 = 29/8 + 76/8 + 81/8 = 186/8 in.
b. 186/8 times 2 = 372/8 in
c. the shortest plane would be 27/8 and the largest would be 19/4 or 38/8.
If you subtract the two, you get 11/8. The difference is 11/8 in.
