Raina spent $72 on fruit at the grocery store. She spent a total of $80 at the store. What percentage of the total did she spend on fruit?

She spent 90% percent on fruits.

Step-by-step explanation:

72:80*100 =

( 72*100):80 =

7200:80 = 90

Now we have: 72 is what percent of 80 = 90

Question: 72 is what percent of 80?

Percentage solution with steps:

Step 1: We make the assumption that 80 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that $100\%=80$.

Step 4: In the same vein, $x\%=72$.

Step 5: This gives us a pair of simple equations:

$100\%=80(1)$.

$x\%=72(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{80}{72}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{72}{80}$

$\Rightarrow x=90\%$

Therefore, $72$ is $90\%$ of $80$.

I have to clear something, I didnt make this process but search it on the internet, if you want more information in the link below. Hope this information from the web helped you in the question.

the nearest power is 1.651.

means 7482 to the 1.651th power is almost equal to 2489287

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
