It’s A because when you add the anti force to the molecular cause of the yah
The relation between a and s is given to be:
a = 640s
where,
a = number of acres
s = number of square miles
We are to find the number of acres for 7.5 square miles.
This means, s = 7.5
Using the value in the formula, we get:
a = 640 x 7.5 = 4800 acres
So the answer to this question is option B
Answer:
52.0 m
Step-by-step explanation:
The triangle formed by the flagpole, the ground and the 30° line is a right triangle, with x as the required length to be found.
Using the tangent ratio
tan30° = 
= 
( multiply both sides by x )
x × tan30° = 30 ( divide both sides by tan30° )
x = 
≈ 52.0 m
Answer:
3 +4 i
Step-by-step explanation:
x + sqrt(yz)
Let x = 3 y=2 and z = -8
3 + sqrt(2*-8)
3+ sqrt(-16)
3 + sqrt(16) sqrt(-1)
We know sqrt(-1) = i
3 +4 i
Answer:
2t + 4f = 100
t+f =42
Step-by-step explanation:
t= two point questions
f =four point questions
2t + 4f = 100
t+f =42
there are 34 two point questions and 8 four point questions
to solve multiply the second equation by -2
-2t -2f = -84
add this to 2t +4f = 100
2t + 4f = 100
-2t -2f = -84
-----------------------
2f = 16
divide by 2
f = 8
there are 8 four point questions
t+f=42
t+8 = 42
subtract 8
t = 34
there are 34 2 point questions
