First, determine the area of the floor of the new room by multiplying the dimensions in feet. 
                                      Area = (12 ft)(15.5 ft) = 186 ft²
Then, we convert the calculated area to yards
                              (186 ft²)(1 yd/ 3 ft)² = 20.67 yd²
Given that the supplier only delivered 20 yd², approximately 0.67 yd² of your floor will not have carpet.

9. The sum of two numbers is 25 and whose product is 156. find the two numbers.​
lord [1]

Answer:

x = 12

y = 13

Step-by-step explanation:

Let's assume the two numbers as x and y.

The sum of the two numbers is 25

So,

  • x+y = 25
  • y = 25 - x

The product of the two numbers is 156

  • xy = 156
  • x(25 - x) = 156
  • 25x - x² = 156
  • x² - 25x + 156 = 0
  • x² - 13x - 12x - 156 = 0
  • (x - 12) • (x - 13) = 0
  • x - 13 = 0
  • x = 13
  • x - 12 = 0
  • x = 12

Hence, the two numbers are 13 and 12.

Can you give me a example on how to do this that would be really helpfull
Rom4ik [11]
We'll do the first one.  I can't read the variable, but it looks like a \theta so that's what I'll use, but it doesn't matter.

First, get the variable by itself:

\theta

You get that before you multiply each side by two.  

 Now, you color the line so that all values that are less than 6 are shaded, so you put an open circle at 6 since it's not included and then you shade everything to the left.

A car starts on a trip and travels at an average speed of 50 miles per hour. Two hours later, a second car starts on the same tr
umka21 [38]

The distance traveled by first car is 50t + 100.

The distance traveled by second car is 70t.

The distance between the two cars after time, t is d = 100 - 20t.

The ratio of the distance traveled by the cars is (70t) / (50t + 100).

<h3>Distance traveled by each vehicle is calculated as follows;</h3>

The distance traveled by each vehicle at the given time is calculated as follows;

<h3>Distance traveled by first car</h3>

D₁ = speed x time

D₁ = 50(t + 2)

D₁ = 50t + 100

<h3>Distance traveled by the second car</h3>

D₂ = 70t

<h3>Distance between the two cars after time, t</h3>

d = D₁ - D₂

d = (50t + 100) - 70t

d = 100 - 20t

<h3>Ratio of the distance traveled by the cars</h3>

D₂/D₁ = (70t) / (50t + 100)
