Answer:
Step-by-step explanation:
2 and 38/45 square yards can be sanded in 3.2 hours.
Step-by-step explanation:
1/2 of an hour is 30 minutes. so 4/9 for every 30 minutes. 1 hour is 8/9. So 3 2/10 would be 3 hours =24/9=2 6/9 and 2/10 would be ( if 5/10 is 30 minutes then 2/10 is 12 minutes.) 8/9 x 1/5 = 8/45. (24 x 5 = 120) 120/45 + 8/45 is 128/45 = 2 38/45

Here is an example f(x)X squared minus 6x plus five
Answer:
Step-by-step explanation:
angle a=40 degree (being vertically angles)
angle a + 90 +angle b=180 degree (being sum of interior angles of a triangle)
40 +90 +angle b=180
130 + angle b=180
angle b=180-130
angle b =50 degree
vrtically opposite of angle b
vertically opposite of angle b + missing angle=65 degree (sum of two intrior opposite angle is equal to the exterion anle formed)
40 degree + missing angle=65
missing angle=65-40
missing angle=25 degree
angle c+ vertically opposite of angle b + missing angle=180 degree (being sum of interior angles of a triangle)
angle c +50 +25 =180
angle c+75=180
angle c=180-75
angle c=105 degree
This is an example of a normal distribution. An average weight is 14 ounces and a standard deviation is 0.7 ounces.
14.7 = 14 + 0.7 = Average + 1 Standard Deviation.
It means that the percent of cans that will weigh over 14.7 ounces is:
100% - ( 50 % + 34 % ) = 100% - 84% = 16%
16% of 100 cans: 16/100 * 100 = 16.
Answer: 16 cans.
