So, she paid (75-17.34=57.66) for the purchase
Or, the jeans costed 57.66-3.26=54.4 (prize minus sales tax)
But she got a 10 dollars off! so that means that the jeans actually costed 64.4
now, the 64.40 was the prize discounted by 30%:
64.40=(100-30)%*x
where x was the original prize
64.40=0.7x
644=7x
x=644/7
x=92
so the original prize was 92 dollars.
The first one I believe is five because it says ten times as many as ___________ is fifty so you take five times ten you get fifty.
Hi there!
We'll be finding the area of the entire middle rectangle (the big one), since that is the lateral area. It has a height of 15 and a length of 18.
15 x 18 = 270
The correct answer is the first option, 270m^2.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
3.5%
Step-by-step explanation:
In this case, the final probability would be the product of the two probabilities that the plating shows us:
First probability would be:
We are told that three quarters of the equipment (3/4) in the laboratory and the other quarter (1/4) near the pond, we are interested in the latter, that is, the probability is 1/4 = 0.25
Second probability:
We are told that 14% collected insects, therefore it would be 0.14
The final product is the question they ask us:
0.25 * 0.14 = 0.035
Which means that the joint probability is 3.5%
