Answer:

8.11

Step-by-step explanation:

You round it up because the 3rd number (thousandths) is 5 or above, and since it's 7 you round that up and drop off the last number.

I=$26.25I=$26.25, P=$500P=$500, t=18 t=18 months

Travka [436]

Next time, please include the directions for the problem you post. Here it appears that you have given the values of I, P and t two times each.
Unfortunately, I have to guess what you're looking for.

Assuming that I=$26.25 is the interest earned on Principal P=$500, and that t is the length of time over which the Principal earns interest,

I=Prt. With I, P and t given, it's obvious that our job is to find the annual interest rate, r. So, from I=Prt, we get

$26.25 = $500 (r) (1.5 years) Solve this for the interest rate, r.
Express r both as a decimal fraction and as the equivalent percentage.

Work out an estimate for square root 1.13 + 2.84 x 9.33

Feliz [49]

hi there!

 $\large \rm = \color{brown} 27.6272 \: \\ \tt in \: \: alternate \: \: form \\ \\ \large \tt \color{cyan} \frac{17267}{625} , \color{red}27 \frac{392}{625}$ 

<h2 />

Step-by-step explanation:

 $\tt1.13 + 2.84 \times 9.33$ 

multiply the number

 $\tt \color{green}1.13 + 26.4972$ 

add the number

 $= \tt \color{green}27.6272 \\ \\ \tt \color{pink}or \: \: in \: \: alternate \: \: form \\ \\ \tt \color{purple} \frac{17267}{625} \tt \color{blue} \: , \: 27 \frac{392}{625}$
