<span>If 100C2 has a value of 4,950, what is the value of 100C98?
10C2 is the number of groups of 2 that can be formed from 100 objects.
Note: Each time a group of 2 is selected you automatically form
a second group of 98. Therefore: 10C2 = 10C98 = 4950 is your Answer</span>

100C2 is a count of the number of sets of two you can drawfrom a set of 100 items. But every time you draw a set of 2 from 100 you haveautomatically determined a set of 98 that you did not select. so the answer is A. 4950

27millimeters. 1cm/10mm

Alla [95]

If you would like to know how many centimeters are 27 millimeters, you can calculate this using the following steps:

1 cm ... 10 mm
x cm = ? ... 27 mm

1 * 27 = 10 * x
27 = 10 * x /10
x = 27/10
x = 2.7 cm

The correct result would be 2.7 cm.

Suppose a computer manufacturer has the total cost function

S_A_V [24]

Answer:

(a) P(x) = 300 x - 3600

(b) P(340) = $ 98400

Step-by-step explanation:

Part (a):

The Profit function is the difference between the revenue function (R(x)) and the Cost (C(x)) function:

P(x) = R(x) - C(x)

P(x) = 384 x - [84 x + 3600]

P(x) = 384 x - 84 x - 3600

P(x) = 300 x - 3600

Part (b):

The profit on 340 items is:

P(340) = 300 (340) - 3600

P(340) = 102000 - 3600

P(340) = $ 98400

Part (c):

To avoid losing money, the profit P(x) has to be larger or equal than zero. That is:

P(x) $\geq$ 0

300 x -3600 $\geq$ 0

300 x $\geq$ 3600

x $\geq$ 3600/300

x $\geq$ 12

So at least 12 items must be sold to avoid losing money.

Celia uses the steps below to solve the equation Negative StartFraction 3 over 8 EndFraction (negative 8 minus 16 d) + 2 d = 24.

Troyanec [42]

The error in the steps is that In step 1, she should have also distributed -3/8 over –16d, to get 3 + 6 d + 2 d = 24

<h3>Simplifying linear equations</h3>

Given the following equation as shown below

-3/8(-8-16d)+2d = 24

Step 1 Distribute -3/8 over the expression in parentheses

3 + 6d + 2d = 24

Simply the like terms

3 + 8d = 24

Subtract 3 from both sides of the equation.

8d = 24 - 3

8d = 21

d = 21/8

Hence the error in the steps is that In step 1, she should have also distributed -3/8 over –16d, to get 3 + 6 d + 2 d = 24

TRUE OR FALSE: A fraction of something is always equal to a fraction of another something

Mice21 [21]

Answer:

FALSE

Step-by-step explanation:

$\frac{x}{y}$ and $\frac{y}{x}$ are not equal.

If we assign numbers to both variables, for example x=1 and y = 2, we get:

$\frac{1}{2}$ $\neq$ $\frac{2}{1}$ . This shows that .5 is not equal to 2, therefore a fraction of something (x) is not always equal to a fraction of another something.
