Well, when it comes to math, I gotta admit, I'm not the smartest cookie in the cookie jar, but if you take 20 2/5 and divide it by 2/5, you should be left with the number of sheets of sheetrock there are in the stack. To divide it, you my have to convert the fraction to a decimal, just FYI. Considering this is marked as a college-level question, I assume you already know how to do this. Hope this helps ya, pal.
Answer:
y=2x-14
Step-by-step explanation:
y=2x+8
y-y1=m(x-x1)
y-(-6)=2(x-4)
y+6=2x-8
y=2x-8-6
y=2x-14
Answer:
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
Their backyard is rectangular, with a length of 3x – 5 feet and a width of 4x – 10 feet. This means that the area of the backyard is
(3x - 5)(4x - 10)
= 12x² - 30x - 20x + 15
= (12x² - 50x + 15) square feet
Their rectangular swimming pool, along with its surrounding patio, has dimensions of x + 8 by x – 2 feet. This means that the area occupied by the swimming pool and its surrounding patio is
(x + 8)(x - 2)
= x² - 2x + 8x - 16
= x² + 6x - 16
Assuming the swimming pool and its surrounding patio will not be covered with new grass, then the area of the region of the yard that they want to cover with new grass is
12x² - 50x + 15 - (x² + 6x - 16)
= 12x² - 50x + 15 - x² - 6x + 16
= 12x² - x² - 50x - 6x + 15 + 16
= 11x² - 56x + 31 square feet
answer:
mean: 15.8
median: 12
mode: no mode
range: 27
step-by-step explanation:
- first know how to find each of the above and what they are
- mean = (avg) add all the numbers, then divide by the number of numbers
- median = the middle number from increasing order
- mode = the one that repeats the most
- range = the difference between the largest and smallest number
8, 35, 10, 12, 14
<u>mean</u>
8 + 35 + 10 + 12 + 14 = 79
79 / 5 = 15.8
<u>median</u>
- put them from smallest to largest
8, 10, 12, 14, 35
- 12 is the median OR the middle number
<u>mode</u>
- no number repeat, so no mode
<u>range</u>
35 - 8 = 27
