Answer:
63
Step-by-step explanation:
A composite number is a whole number. It can be defined as a number that is divisible by 1, itself and other factors. This means a composite number has two or more factors. A prime number cannot be a composite number.
The seven smallest composite numbers are:
4, 6, 8, 9, 10, 14, 16,
Their total sum = 4 + 6 + 8 + 9 + 10 + 14 + 16 = 63
Therefore, the sum of the seven smallest composite numbers which cannot be determined to be composite simply by using the divisibility rules (for 2,3,4,5,6,8,9 or 10) is 63.
the complete question is
While driving in an exotic foreign land you see a speed limit sign on a highway that reads 180,000 furlongs per fortnight. How many miles per hour is this? (One furlong is 1/8 mile, and a fortnight is 14 days. A furlong originally referred to the length of a plowed furrow.)
Step 1
<u>convert (furlongs per fortnight) to (miles per fortnight)</u>
180,000 furlongs per fortnight=180,000*(1/8)=22,500 miles per fortnight
Step 2
<u>convert miles per fortnight to miles per hour</u>
1 day=24 hour
14 day=24*14=336 hours
22,500 miles per fortnight=22,500/336=66.96 mph
therefore
<u>the answer is</u>
66.96 mph
Answer:
A = 352 in²
Step-by-step explanation:
A=2(wl+hl+hw) Use this equation to find the surface area of the rectangular prism
A = 2(8x12 + 4x12 + 4x8) Multiply
A = 2(96 + 48 + 32) Add
A = 2(176) Multiply
A = 352 in²
