For (4, 3) the least common multiple (LCM) is 12.

Therefore, the least common denominator (LCD) is 12.

Rewriting as equivalent fractions with the LCD:
3/12, 8/12
Hope i helped!

The Lowest Common Denominator of two fractions is the LCM (Lowest Common Multiples) of the two denominators.

Multiples of 4: 4, 8, 12, 16, 20
Multiples of 3: 3, 6, 9, 12, 15, 18
the first multiple they share is the LCM
In this case that would be 12

Therefore your LCD for this problem would be 12

Write the formula for an exponential function with initial value 300 and decay factor 0.73
postnew [5]

Answer: 300*0.73^x

Step-by-step explanation:

300 is the initial value and every time x goes up by 1, the value get multiplied by 0.73

when x=3

then the value would be 300*0.73*0.73*0.73 or 300*0.73^3

then for x amount of times the equation would be 300*(0.73 x times ) or 300*0.73^x

X and y are positive integers. explain why incorrect to claim that
dedylja [7]

You can find counterexamples to disprove this claim. We have positive integers that are perfect square numbers; when we take the square root of those numbers, we get an integer.

For example, the square root of 1 is 1, which is an integer. So if y = 1, then the denominator becomes an integer and thus we get a quotient of two integers (since x is also defined to be an integer), the definition of a rational number.

Example: x = 2, y = 1 ends up with \frac{2}{\sqrt{1}} = \frac{2}{1} which is rational. This goes against the claim that x/\sqrt{y} is always irrational for positive integers x and y.

Any integer y that is a perfect square will work to disprove this claim, e.g. y = 1, y = 4, y= 9, y = 16. So it is not always irrational.

If QRST is a rectangle with QT = 30 and RS = 4x + 10, find x.
ArbitrLikvidat [17]
The opposite side pairs in a rectangle are congruent, so basically QT would be congruent to RS when you draw the rectangle and label the points.
4x+10=30
4x=20
x=5

Can someone give me the value of x
Diano4ka-milaya [45]

The shape has 7 sides.

The sum of the interior angles is (7-2)180 = 5 * 180 = 900 degrees.

Divide the total sum by 7:

X = 900 /7 = 128.6 degrees.
