Answer:
92.8 km
Step-by-step explanation:
s=d/t
58=d/1.6
58*1.6=d
92.8=d
Answer:
5 times a number increased by 2 is the same as 8 more than 3 times the number.
Step-by-step explanation:
Answer:
Step-by-step explanation:
If it have more than 2 divider its composite but its divider is only one and its self only its prime.1 isn't neither prime nor composite
hence, the common ratio of the given G.P. is 3 or −3.
Answer:
QR = 17 cm
Step-by-step explanation:
Δ RST is a 5- 12- 13 triangle with hypotenuse RT = 13 cm , then
TS = 5 cm and PT = 2 × 5 = 10 cm
So PS = 10 + 5 = 15 cm
PS is parallel to the vertical line from vertex Q and intersects the horizontal line projected from SR of length 20 - 12 = 8 cm
Using the right triangle formed calculate QR using Pythagoras' identity
QR² = 15² + 8² = 225 + 64 = 289 ( take square root of both sides )
QR =
= 17
