1. Find the Least Common Multiple of these two monomials: See picture

gtnhenbr [62]

Answer:

The last choice is correct

$LCM=120a^4b^7c^5$

Step-by-step explanation:

Least Common Multiple (LCM)

To find the LCM we can follow this procedure:

List the prime factors of each monomial.

Multiply each factor the greatest number of times it occurs in either factor.

We have two monomials:

$12a^4b^2c^5$

$40a^3b^7c^1$

The prime factors of the first monomial are:

$2^2,3,a^4,b^2,c^5$

The prime factors of the second monomial are:

$2^3,5,a^3b^7c^1$

LCM = Multiply $2^3*3*5*a^4*b^7*c^5$

These are all the factors the greatest number of times they occur.

Operating:

$LCM=8*15*a^4*b^7*c^5$

$\boxed{LCM=120a^4b^7c^5}$

The last choice is correct

Alloy, c, weighing 500 ounces and having 35% aluminum, is obtained from melting together x ounces of alloy, a, containing 25% al

boyakko [2]

From the given scenario in this item, we can say that the sum of x and y is 500. By the aluminum balance, the equation that we can formulate from this,
0.25x + 0.40y = (500)(0.35)
The system of linear equations that can best express the given is,
x + y = 500
0.25x + 0.40y = 175

AABC Is dilated by a scale factor of 3 with the origin as the center of dilation to form AA' BC. The slope of AB is -1.2. The le

alukav5142 [94]

Answer:

The slope of new figure A'B'C' = -1.2

A'B' = 3p units

A'C' = 3q units

Step-by-step explanation:

The value of each of the corresponding length of dilated figures (new image) = scale factor multiplied by the corresponding length in original figure.

scale factor = 3

Length of AB = p units

the length of AC = qunits

the length of BC = runits

A'B' = 3p units

A'C' = 3q units

B'C' = 3r units

slope of new figure = slope of previous figure

The slope remains the same = -1.2

Simplify the radical expression.

NNADVOKAT [17]

$\\\dfrac{ \sqrt{6}}{ \sqrt{2n} } \\ \\
 = \dfrac{ \sqrt{3 \times 2}}{ \sqrt{2 \times n} } \\ \\
 = \dfrac{ \sqrt{3} \times \sqrt{2} }{ \sqrt{2} \times \sqrt{n} } \\ \\ = \dfrac{ \sqrt{3} }{ \sqrt{n}} \\ \\ = \sqrt{ \dfrac{3}{n}}$
