Answers

Answer: 1,796

Step-by-step explanation:

We are given that : At the chicken ranch this morning there were 7,149 chicks.

i.e. The number of new chicks before today = 7,149

Later today some more chicks hatched. now the ranch has 8,945 chicks.

i.e. The number of new chicks after today = 8,945

Then, By Subtraction operation

Number of new chicks hatched today = ( Number of new chicks after today) - (Number of new chicks before today )

= 8,945- 7,149 = 1,796

Therefore , the number of new chicks hatched today = 1,796

We need common denominator, which in this case is 40.

6*5 is 30 and 4*8 is 32.

We add these up 62/40

Now add the wholes, 5+4 is 9

We have an improper fraction, which will add 1 to 9, causing the answer to be C.

A number is equal to twice a smaller number plus 3. The same number is equal to twice the sum of the smaller number and 1. How many solutions are possible for this situation?
Infinitely many solutions exist because the two situations describe the same line.
Exactly one solution exists because the situation describes two lines that have different slopes and different y-intercepts.
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Exactly one solution exists because the situation describes two lines with different slopes and the same y-intercept.

Seats at a local entertainment venue sell for $5 each in the lower level and $4 each in the upper level. If all the seats are sold, the total revenue is $2,674. At a recent event, only 1
7
of the lower level seats and 4
7
of the upper level seats were sold, for a total of 262 seats. Let x represent the total number of lower level seats, and let y represent the total number of upper level seats.

Which equation represents the total revenue?

Which equation represents the total number of tickets sold?

How many seats does each section have?

Answers

Answer:

The first slot is "5x + 4y = 2674". The second slot is "1/7x + 4/7y = 262". The third slot is "210 lower and 406 upper".

Step-by-step explanation: I got it right on Edge. :D

The lower section has 210 seats, and the upper section has 406 seats

The lower seats are represented with x, while the upper seats are represented with y

So, the equation that represents the total revenue is:

[tex]5x + 4y = 2674[/tex]

And the equation that represents the total number of tickets sold is

[tex]\frac 17x + \frac 47y =262[/tex]

Next, we plot the graphs of both equations (see attachment)

From the graph, the lines intersect at (x,y) = (210, 406)

Hence, the lower section has 210 seats, and the upper section has 406 seats

Answers

Answer:

1/13

Step-by-step explanation:

the answer is up at the top

Answer:

Here's an example to help guide you to answer this question dear.

Step-by-step explanation:

A jar contains 10 red marbles, 4 white marbles, and 2 blue marbles. Two are drawn in sequence, not replacing after each draw.

Quantity A is greater.

Why?

Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue. The probabilities of each of these events, added together would be (2/16) * (14/15) + (14/16) * (2/15) = 0.2333333333; therefore, A is more probable.
