Answer:
18
Step-by-step explanation:
3x + 2x = 90
5x = 90
5x/5 = 90/5
x = 18
First you would want to covert the yards into inches so you don’t have any fractions. It would then be 14:180 and x:3600 so to solve this proportion you would next get 180x = 50,400 then you would divide 180 by 50,400 to isolate the variable which would then give you 280 inches

Answer with explanation:</h2>
Given : The distribution of the lengths of a commercially caught fish is bell-shapped ( i.e. normally distributed ) with and .
Let x be the length of a commercially caught fish .
Any fish measuring less than 20 cm must be released.
1) The probability that a fish measuring less than 20 cm :
∴ The proportion of fish that must be released is about 0.16.
2) The probability that a fish measuring between 20 cm and 32 cm :
If total 500 fish are caught, then number of fish have lengths between 20 cm and 32 cm = 0.8185 x (500)=409.25 ≈409
The nearest option from the given options is "408".

Answer:
$14.43¢
Step-by-step explanation:
We are given; pounds, 1 pound = $4.20 and pounds,1 pound = $3.80 that Andrea bought.
Now we need to find her total cost. To do that, we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert to a decimal. It is 1.4. Now we can set up a graph.
<u>Avocados</u>
Switch sides
Apply rule:
Multiply both sides by 1.4
Simplify
So, her cost for avocados is $5.88¢
Now we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert to a decimal. It is 2.25. Now we can set up a graph.
<u>Asparagus</u>
Switch sides
Apply rule :
Multiply both sides by 2.25
Simplify
So, her cost for asparagus is $8.55¢
<u>Total cost</u>
Now that we have found out how much both of the fruits Andrea bought costs, we need to sum it up (meaning add it) to find the total cost:
$5.88¢ + 8.55¢ =
5.88 + 8.55 = 14.43
Therefore, Andrea's total cost of the fruits is $14.43¢
