Answer:
± 1/4 sqrt((400-y)) =t
Step-by-step explanation:
Y=-16t^2 + 400
Subtract 400 from each side
y - 400 = -16t^2 +400-400
y-400 = -16t^2
Divide by -16t^2
(y-400)/-16 = t^2
(400-y)/16 = t^2
Take the square root of each side
±sqrt((400-y)/16) =sqrt(t^2)
±sqrt((400-y)) / sqrt(16) =t
± 1/4 sqrt((400-y)) =t
Answer:
3x + 4
Step-by-step explanation:
We have a product of 3 and x. That's rewritten as 3x. We then have 4 more, so we add 4. That gives us the final answer of: 3x+4. (It is 1-4x for the third one). ( The fourth one) The sum of seven and the quotient of a number x and eight
Here, x be the number.
" quotient of a number x and eight" translated to x/8
Sum means '+'
"sum of seven and the quotient of a number x and eight" translated to 7+ x/8 +56+x/8
then; the given statement is 56+x/8
⇒
Therefore, the given statement is 56+x/8
Answer:
35%
Step-by-step explanation:
Multiply each side by 2.5 to get 35/100 which will give you 35%.
