Answer:

22x + 100 = 25x + 70, 10 yards

Step-by-step explanation:

Set the number of square yards of carpeting as x.

So, the cost of Country Carpets is: 22 * x + 100

And the cost of City Carpets is: 25 * x + 70.

In order for the costs to be the , the equations need to be equal.

22x + 100 = 25x + 70

Subtract 22x from both sides.

100 = 3x + 70

Subtract 70 from both sides.

3x = 30

x = 10

10 square yards

Answer:

1. it is not a direct variation because the value k is not kept throughout the ordered pairs

2. -a^5 - 2a³ + 2a², leading coefficient is -1

Step-by-step explanation:

1. to find the direct variation, we will use y/x = k with k representing our constant throughout the chart. if every value is equal to k, it is a direct variation

for this problem we will assume that the cup sizes are x and the cost is y

so the ordered pairs are (8, 0.90), (12, 1.35), (16, 1.80), and (24, 2.25)

.90/8 = 0.1125 <-- this is our k value for which every result has to be equal to

1.35/12 = 0.1125

1.80/12 = 0.1125

2.25/24 = 0.09375

since the value k was not kept throughout the ordered pairs, this is not a direct variation

2. the standard form of a polynomial is the exponents in descending order.

we have the following polynomial: 2a² - a^5 -2a³

to write it in standard form, we will go in descending order of the exponents. the largest exponent being first

-a^5 - 2a³ + 2a²

the leading coefficient of the polynomial is -1, as there is a negative sign in front of the newly formed polynomial

To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of in

erastova [34]

Answer: $x= 187.5p$

Step-by-step explanation:

Given : An equation relating packets to bytes of information : $b = 1,500p$ where p represents the number of packets and b represents the number of bytes of information.

1 byte = 8 bits

Let x= Number of bits such that 1 b = 8x

Put b = 8x in given equation , we get

$8x=1500p$

Divide both sides by 8 , we get

$x= 187.5p$

Hence, the equation represent the relationship between the number of packets and the number of bits : $x= 187.5p$
