Answer:
can you explain more pls
Step-by-step explanation:
Answer:
f = .39
Step-by-step explanation:
d (v) = 2.15 v^2 / (64.4 f)
v = 40
d = 138
substitute these in
138 = 2.15 (40)^2 / (64.4 *f)
simplify
138 = 2.15 (*1600) / (64.4 *f)
138 = 3440 / (64.4 *f)
multiply each side by 64.4f
138 * 64.4 f = 3440
8887.2 f = 3440
divide by 8887.2
8887.2 f /8887.2= 3440/8887.2
f=.38707
to the nearest hundredth
f = .39
Pretty sure it’s 4 idk tho this is a tough one. Hahahaha
13/25
first off, to turn a fraction into a decimal, you divide numerator by denominator
in this case, 13/25=.52
answer is .52
Answer:
Sachet town is 12km from the airport
Step-by-step explanation:
In this question, we are asked to calculate the distance from sachet town to the airport.
This can be calculated by referring to a diagrammatic representation. Please check attached file.
Let’s proceed with the calculations however.
From the question, we can see that we have formed a Right angled triangle from the diagram and we need to calculate the distance x.
Mathematically;
x^2 + 16^2 = 20^2
x^2 = 20^2 - 16^2
x^2 = 400 - 256
x^2 = 144
x = sq.rt of 144
x = 12km
