Answer:

660

Step-by-step explanation:

First, let's find the prime factorization for both numbers.

132 = 11 x 12

12 = 3 x 4

4 = 2 x 2

132 = 2 x 2 x 3 x 11

60 = 5 x 12

12 = 3 x 4

4 = 2 x 2

60 = 2 x 2 x 3 x 5

Now, to find the lowest common multiple, we just need to multiply each number the most times it is seen in either number.

132 = 2 x 2 x 3 x 11

60 = 2 x 2 x 3 x 5

The first number is both is 2, which appears at most twice in either list so we will multiply two 2s to find the LCM.

Both numbers also have at most one 3, one 5, and one 11, so to find our LCM, we just need to multiply all these numbers together:

2 x 2 x 3 x 5 x 11 = 660

The LCM of 132 and 60 is 660.

Hope this helped!

Answer:

The graph has only one x-intercept

Step-by-step explanation:

we have

$f(x)=-4x^2+12x-9$

we know that

The discriminant of a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$D=b^{2}-4ac$

in this problem we have

$f(x)=-4x^2+12x-9$

$a=-4\\b=12\\c=-9$

substitute

$D=12^{2}-4(-4)(-9)$

$D=144-144$

$D=0$

The discriminant is zero

That means ----> The quadratic equation has one real solution

The graph has only one x-intercept

Rachel has a bag of fruit that has a mass of 50 hectograms. Rachel converts this mass to centigrams. Her work is shown below.

Alinara [238K]

Answer:

She should have multiplied by 10,000

Step-by-step explanation:

Given table:

$\begin{array}{| c | c |}\cline{1-2} \sf kilo & 1,000 \\\cline{1-2} \sf hecto & 100 \\\cline{1-2} \sf deka & 10 \\\cline{1-2} \sf unit & 1 \\\cline{1-2} \sf deci & 0.1 \\\cline{1-2} \sf centi & 0.01 \\\cline{1-2} \sf milli & 0.001 \\\cline{1-2}\end{array}$

To find the conversion rate:

$\sf \dfrac{hecto}{centi}=\dfrac{100}{0.01}=10000$

Therefore, 1 hectogram = 10,000 centigrams

So when converting hectograms to centigrams, multiply the mass by 10,000.

⇒ 50 hg × 10,000 = 500,000 centigrams

Rachel's error was that she should have multiplied by 10,000.

A line is drawn through (–4, 3) and (4, 3). Which describes whether or not the line represents a direct variation? The line repr

Dovator [93]

Answer:

Line does not represent direct variation.

Step-by-step explanation:

If the line goes thru the origin, it represents direct variation. Otherwise it does not.

Start by finding the slope of this line:

As we move from (-4,3) to (4,3), x increases by 8 but y does not change. Thus, the slope is 0/8, or just 0. Thus, the equation of this line is y = 3, which does NOT go thru the origin; thus, the points given do NOT represent direct variation.
