By definition,
tanC = (opposite side)/(adjacent side)
= 8.77/2
= 4.385
From the calculator, obtain
m∠C = atan(4.385) = 77.1°
Answer: 77° (nearest whole degree)
You sum two vectors by summing the correspondent coordinates:
So, you have
Answer:
distance covered in 2 hours = 80 km
distance covered in 1 hour = 80÷2 = 40 km
distance covered in 7/2 hours = 40 × 7/2
= 140 km
(3 1/2hours = 7/2 hours)
Answer: 4 pairs of socks
Step-by-step explanation:
According to the described situation, Anika spends 
in 1 pair of shin guards for 
and 
pairs of socks for 
each pair.
So, we can express this in the following equation:
Isolating we will find the pairs of socks:
Hence, Anika bought 4 pairs of socks.
To multiply fractions, the numerator of the product is the product of the numerators, likewise for the denominators.
(2/3) x (4/7) x (14/5) = (2 x 4 x14) / (3 x 7 x 5)
= (112) / (105) = 1 and 1/15 .
