Answer:
9
Step-by-step explanation:
3/729= 9
729=9^3
=3/9^3= 9
Hope this helps! Please give brainiest!
I'll do 3 and 4, and you can do 5 and 6 on your own!
For 3, we know that a perpendicular line's slope is -1/the other one, so the form is y=x/5+b (b being any number). Plugging -5 and -3 in, we get -3=-1+b. Adding 1 to both sides, we get -2=b and our equation being y=x/5-2 (since our standard form is y=mx+b with y and x remaining variables)
For 4, parallel means the same slope, so we have y=-2x/5+b. Plugging (2,4) in, we get 4=-4/5+b. Adding 4/5 to both sides, we get 4+4/5=b and our equation being y=-2x/5+4+4/5
<h3>Interest rate required for Antonio’s investment to double in value in 12 years is 8.3 % per annum</h3>
<em><u>Solution:</u></em>
Given that,
Antonio wants to invest $7600 in a saving account
Antonio’s investment to double in value in 12 years
To find: Rate of interest
<em><u>The total amount using simple interest is given as:</u></em>

Where,
p is the principal
r is the rate of interest
t is the number of years
From given,
p = 7600
t = 12 years
r = ?
Antonio’s investment to double
Therefore,
A = 2(7600) = 15200
<em><u>Substituting the values we get,</u></em>


Thus interest rate required for Antonio’s investment to double in value in 12 years is 8.3 % per annum
A lot maybe more!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
58 degrees
Explanation
If you have a triangle with the angle measures of abc as 58 degrees, 102 degrees and 20 degrees you can multiply them in order of abc so 58 degrees is angle a, 102 degrees is angle b and 20 degrees is angle c. Then you just put in angle a for d which would be 58 degrees and angle e for b 102 degrees and angle f for c which would be 20 degrees
