Answer:
Let the 3 digits are xyz.
For x we have 6 options, for y - 5, for z - 4 since all digits are different.
<u>Number of options:</u>
Even numbers will have z = 2, 4 or 6, then
x - 5 options, y - 4 options
<u>Number of options:</u>
2\5 + 2\4
Lcm of 4 and 5 is 20
So 20 divided by 5 is 4 × 2 = 8 and 20 divided by 4 is 5 × 2 = 10
10+ 8 =18\20 = 9\10
Answer:
20*30=600
This could be written out with addition instead, as 20 'times' 30
30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30+30
=600
Answer:
90
Step-by-step explanation:
Start with changing 35% and 30% to a decimal.
35% = .35%
30% = .30%
Then multiply 105 by .30%. ( but don't put the percent sign in the calculator when multiplying)
105 x .30% = 31.5
Then you want to divide 31.5 by .35%
31.5 / .35% = 90
If you divide 120,000 by 1,500 you will get the amount that it costs per square feet which you would then multiply by 2,400 to get 192,000. So the answer is $192,000
