I did 2-
d) Square root of 16 plus 3 to the second power (exponent)
3 to the 2nd power = 9
square root of 16 is 4 so 9+4=13
g) Square root of 25 to the power of 2 + (2+3)
2+3= 5 then square root of 25 = 5 to the second power is 25 = 30
All u have to do is mulitiply 5 times 4 and get 20
Answer:
The expression represents the total cost of the bag which contain x number of goby and x number of shrimp.
Step-by-step explanation:
Each goby fish costs $15 and each shrimp costs $10.
Each bag has an equal number of goby fish and shrimp.
So. let each bag has x number of goby and x number of shrimp
so, the cost of the bag = 15x + 10x
Take x as a common
so, the total cost = x (15+ 10)
so, the expression represents the total cost of the bag which contain x number of goby and x number of shrimp.
Answer:
C) 3/5
Step-by-step explanation:
Have you heard of this way to memorize the trig ratios?
SOH-CAH-TOA (Say it out loud so you remember it.)
It represents these ratios:
Sine = opposite side / hypotenuse
Cosine = adjacent side / hypotenuse
Tangent = opposite side / adjacent side
In this problem, cos C = adj / hyp = BC / AC = 24 / 40.
That simplifies to 3/5
