Given :

A local fish market is selling fish and lobsters by the pound. The fish, f, costs $5.00 a pound, while the lobster, l, costs $8.00 a pound. The fish market sells 20.5 pounds and makes $131.00.

To Find :

How many pounds of fish and pounds of lobster did the market sell.

Solution :

Let, pounds of fish sells are x.

So, pounds of lobsters sells are (20.5 - x) .

Total amount of spend = 5x + 8( 20.5 - x)

5x + 8( 20.5 - x) = 131

5x - 8x + 164 = 131

3x = 33

x = 11

Therefore, number of pounds of fish and lobsters are 11 and 9.5 pounds respectively.

Hence, this is the required solution.

In the spinner below, what is true about the probability of landing on 3 and the probability of landing on 4?
Karo-lina-s [1.5K]

Answer:

C.The probabilities are equal.  

The above statement is the only TRUE statement.

Step-by-step explanation:

Here, the given number of total possibilities are { 0,1,2,3,4,5,6,7,8,9}

So, number of total outcomes = 10

Let E : Event of spinner landing on 3

and E' : Even of spinner landing on 4

{Probability of Event E}  =  \frac{\textrm{Total number of favorable outcomes}}{\textrm{Toatl outcomes}}

\implies P(E) = \frac{1}{10}

⇒ P( landing on 3 ) = 1/10

and  P(E') = \frac{1}{10}

P( landing on 4 ) = 1/10

Now, the given statements are

A.The probability of landing on 3 is less than  probability of landing on 4.

FALSE, as both the probabilities are equal to 1/10.

B.The probability of landing on 3 is greater than probability of landing on 4.

FALSE, as both have same probabilities.

C.The probabilities are equal.

TRUE, both have same probability = 1/10

D.The probabilities cannot be predicted

FALSE, the probability are predictable.

Write an equation of four lines that intersect to form the sides of a parallelogram
horrorfan [7]
The question requires that the four lines that intersect form a parallelogram but not an specific parallelogram, so you are not restricted by a diagram.

You can use these equations for the four lines:

1) y = 0 (it is the x-axis)

2) y = 4 (it is a line parallel to the x-axis, whose y-intercept is 4.

3) y = x (it is an inclined line that intersects both y = 0 and y = 4 lines.

4) y = x + 7 (it is a line parallel to y = x, that also intersect the both y = 0 and y = 4 lines.
