An inequality that represents his purchase is 0.85x + 1.29y < 5. The sign is less than, because you spend less than that, not equal to that.
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
t = 9 / ( 450 × 0.04 ) = 0.5
t = 0.5 years
The time required to
accumulate simple interest of $ 9.00
from a principal of $ 450.00
at an interest rate of 4% per year
<span>is 0.5 years (about 0 years 6 months).</span>
CC. 2 units in positive x and 3 units in positive z
Well first you find the common denominatior of 1/7 and 4/9 which is 63 so then you see how many times does 7 go into 63 so this is part where you multiply 7 and 9 which gives you 63 and then you do how many times 9 go into 63 which is 7 so then you will take 7 times the 4 which is 28 so now your fractions should be 9/63 and 28/63 then now your next step is to add the 9 and 28 which is now 37/63 and you ask yourself and you divide that by any number to get a smaller number which is no so that is your answer
3.375 would be the answer, exponents with decimals is the same as regular exponents, just multiple the base number times the exponent you are working with
