Answer:
3.2
Step-by-step explanation:
Formula to find the simple interest rate :
S.I. =
Formula to find R (simple interest rate) :
R =
Since you have I (interest amount), we can use this formula instead :
R =
R = = 4%/year or 0.04
Now plug this into the first formula
S.I. = = 3.2
i haven't done this in a while so hope this helps !!
<u>Answer:</u>
<em>(2•7a5)</em>
<u>Step-by-step explanation:</u>
<em>Step 1 :</em>
<em>Equation at the end of step 1 :</em>
<em> -2a • (0 - 7a4)</em>
<em>Step 2 :</em>
<em>Multiplying exponential expressions :</em>
<em> 2.1 a1 multiplied by a4 = a(1 + 4) = a5</em>
Replace the second equation y=3x+4 into the first one:
2(3x+4)+5x=30
Now solve for x:
6x+8+5x=30
11x=30-8
11x=22
x=22/11
x=2
Finally, replace x=2 into y=3x+4
y=3*2+4
y=6+4 = 10
So the anwer is x=2, y=10
T=months so if you have 7 months you would plug 7 in for (t)
making the equation g(7) = 2(7)
Answer:
Step-by-step explanation:
45 seconds = 45/60 = 0.75 minutes
7 minutes 45 seconds = 7.75 minutes
One hour = 60 minutes
Number of full laps = 60/ 7.75 = 6000/775 = 7.74
He can make 7 full laps in one hour
