Find the gcf and lcm of 20x^2y^3 60x^3y^2| 40xy^2

1 answer:

7 0

Gcf is the grouping of all the factors common to both groups
lcm is a group of all the factors that has all the elements of both groups

factor
20x^2y^3=2*2*5*x*x*y*y*y
60x^3y^2=2*2*3*5*x*x*x*y*y
40xy^2=2*2*2*5*x*y*y

the GCF=2*2*5*x*y*y=20xy^2
the LCM=2*2*2*3*5*x*x*x*y*y*y=120x^3y^3

Assuming that the rug is rectangular in shape, therefore the formula of area is:

A = l w ---> 1

where l is the length of the rug and w is the width of the rug

We are given that the width of the rug is 5 feet less than the length, therefore:

w = l – 5 ---> 2

Combining equations 1 and 2 and knowing that A = 150 will give us:

l (l – 5) = 150

In the given choices, l = x, therefore:

x (x – 5) = 150

Hence the correct answer is the 1st one (A)

Answer:

Step-by-step explanation:

We need to find the median of:-

73 75 87 65 69 62 81 64 68 101 74 71 89 87

First, we need to arrange the numbers in ascending order as below:-

62, 64, 65, 68, 69, 71, 73, 74, 75, 81, 87, 87, 89, 101

Since there are a total of 14 numbers, let's split it up into two halves (each of seven numbers)

62, 64, 65, 68, 69, 71, 73 ||| 74, 75, 81, 87, 87, 89, 101

The median would be the mean of the two middle numbers i.e. the mean of 73 and 74

Median = $\frac{73+74}{2}$

= $\frac{147}{2}$

= 73.5

So, about half of the students spent less than 73.5 minutes doing homework and about half spent more than 73.5 minutes on homework

Answer:

$2104.36 fixed expenses

$save 209.71 per month

Step-by-step explanation:

985.64+58.30+(2)(154.00)+180.00+128.40+(4)(55.00)+(684.80/6)+(330.00/3) = 2104.36 monthly expenses

2943.20-2104.36 = 838.84

838.84 x 0.25 = 209.71

IceJOKER [234]

Answer:

1. 7^(x-y)

2. z^5x^y

Step-by-step explanation:

The applicable rule of exponents is ...

(a^b)/(a^c) = a^(b-c)

$\dfrac{7^x}{7^y}=\boxed{7^{x-y}}$

$\dfrac{z^{10}x^y}{z^5}=x^yz^{10-5}=\boxed{z^5x^y}$
