If I have a stack of pennies. And I have to tell that without counting whether there are even number of pennies or odd.

Even numbers are the numbers which are divisible by 2 and odd numbers are the numbers which are not divisible by 2.

Then I will put the given pennies in 2 rows and then I will match them to form a pair of 2 pennies. After matching, if there is 1 penny left over, then there is an odd number of pennies and if all the pennies have a match,then there is an even number of pennies.

A submarine on the surface of the ocean descended at a rate of 7 feet per second for 2 minutes. Then it ascended at a rate of 4
kotykmax [81]

Answer:

4,260 feet below sea level (-4,260 feet)

Step-by-step explanation:

The submarine starts at sea level which should be 0 for elevation. And descending 7 feet per second for 2 minutes which means it went down 840 feet ( 7x60x2). Then 4 feet per second for 3 minutes which is 720 feet (4x60x3). Lastly 9 feet per second for 5 minutes which is 2,700 feet (9x60x5). Then you add up those three totals, 840 + 720 + 2,700 = 4,260. So the elevation is -4,260 feet, or 4,260 feet below sea level

Write an equation of the line that passes through the point (3,-2) with slope -2.
Virty [35]

Answer:

y + 4 = -2(x - 3)

Step-by-step explanation:

Use the point-slope formula y - k = m(x - h).  Substitute -2 for k and 3 for h, as well as -2 for m:

y + 4 = -2(x - 3).

Draw a number line to<br><br> represent the inequality.<br><br> y s 23
Mkey [24]

Answer:

The number lines are shown below.

Step-by-step explanation:

In the given problem the sign of inequality is missing.

We know, that there are 4 signs of inequality ">", "<", "≥" and "≤".

The possible inequalityes are

y>23

y

y\geq 23

y\leq 23

In y>23, all points on the right side of 23 are included in the solution set.

In y, all points on the left side of 23 are included in the solution set.

In y\geq 23, 23 and all points on the right side of 23 are included in the solution set.

In y\leq 23, 23 all points on the left side of 23 are included in the solution set.

9 * 12 = 108

16 * 13 = 208

108 / 208

Simplify:

27/52


2.

7 / 10 * 5 / 28

7 * 5 = 35

10 * 28 = 280

Simplify:

1/8
