Answer:
24 buckets
Step-by-step explanation:
Given that :
Dimension of rectangular block = 45 m by 38 m
A bucket of paint will cover 72m² of floor
Total area of floor : Length * Width
Total Area = (45m * 38m) = 1710 m²
Buckets of paint required :
Total area / Area per bucket
= 1710m² / 72m²
= 23.75 buckets
= 24 buckets
Answer:
Step-by-step explanation:
10+18+25+27+35+50=165
n=6
mean =165/6=27.5
x x- mean (x-mean)²
10 -17.5 306.25
18 -9.5 90.25
25 -2.5 6.25
27 -0.5 0.25
35 7.5 56.25
50 22.5 506.25
_____ ________
sum 0 965.5
_____ _________
standard deviation
Answer:
The top right answer choice is correct.
2.3 x 12 = 27.6
27.6 > 27.1
Step-by-step explanation:
Well first off, we know that:
1 foot = 12 inches
To compare the two, we first want to covert 2.3 feet into inches.
2.3 x 12 = 27.6 inches
Now that we have our two values, we need to decide which is greater than the other.
27.6 or 27.1
Both values have a decimal that shows tenths. In this problem, 6 tenths is larger than 1 tenth. Therefore:
27.6 inches > 27.1 inches
Answer:
6.3feet
Step-by-step explanation:
Given data
Radius= 4feet
The expression for the circumference of a circle is
C= 2πr
Substitute
C=2*3.142*4
C=25.136 feet
Also, a 90° arc is 1/4 of the circumference of a circle
Hence the length of the 90° arc is
=25.136/4
=6.284 feet
=6.3feet
