tigry1 [53]

Answer:

Yes, Her father is correct.

Step-by-step explanation:

75/15=5 which means that there will be fifteen rows, with five pennies in each row. Since one side has 5 pennies and the other has fifteen, the sides are different and form a rectangle. To check your work, you can do 15*5 which equals 75 the rectangle of pennies should look like this:

Six people are standing in line for concert tickets. Their average age is 27. The average age of the first four people in line i
DanielleElmas [232]

The best answer for this question would be:

 

D. 32

 

In order to get this, you have to get the sum in the line, which is the first four people. So the solution would be: 4(23) = 92

 

For getting the sum of the people in the last 3 would be: 3(34) = 102

 

Next is the sum of everyone which the solution would be: 6(27) = 162

 

So the initial solution that we have now would be: F + 92 - F + 102- F = 162

 

- F + 194 = 162

 

- F = 162 - 194

 

- F = - 32

 

The (F) here or the fourth person’s age would be= -32 / - 1 or 32

A tank with capacity T gallons is empty. If water flows into the tank from pipe X at the rate of X gallons per minute, and water
Andrej [43]

A tank with capacity T gallons is empty. Tank will be filled in \frac{t}{(x - y)} minutes

<u>Solution:</u>

Given, A tank with capacity T gallons is empty.  

We have to find how many minutes will tank be filled?

Now, Water flows into the tank from pipe X at the rate of X gallons per minute,  

And water is pumped out by pipe Y at the rate Y gallons per minute,  

Then, together in one minute the amount of water filled will be x – y gallons  [as X is greater than Y]

Now, the time take to fill tank = =\frac{\text { capacity of tank }}{\text { amount of water filled per minute }}=\frac{t}{x-y}

Hence tank will be filled in \frac{t}{(x - y)} minutes

Write an inequality that represents the graph.
Anika [276]

Answer:

y - 2x - 1 = 0

Step-by-step explanation:

the slope is :

\tan( \alpha )  = 4  \div 2 = 2

at a pt on graph , when

x = 1 \\ y = 3 \\

therefore, coordinates are (1,3)

The equation is :

(y - 3) = slope \times (x - 1) \\ (y - 3) = 2 \times (x - 1) \\  y - 3 = 2x - 2 \\ y - 2x - 1 = 0
