Interest = Pin = principal * interest rate * number of years
Let interest rate be i, then
600*i*2+150*i*4=90
1200i+600i = 90
i=90/(1200+600)=90/1800=1/20=0.05 or 5%
6/x=27
times both sides by x
6=27x
divide both sides by 27
6/27=x
2/9=x
the missing number is 2/9
<h3>C</h3>
f(x) does have an inverse function since it does pass the horizontal line test
A) the scale factor of the smaller pyramid to the larger pyramid in simplest form is 24:30 = 4:5
b) the ratio of the area of the base of the smaller pyramid to the
larger pyramid.
From the scale factor, the ratio of the area of the base of the smaller pyramid to the larger pyramid is 4^2 : 5^2 = 16:25
You can write it as 2x10x47 then 47x2 is equal to 94 and time it with 10 so it’s 940
