Answer: 6.5 inches
Step-by-step explanation:
From the question, we are informed that Claire is building a dollhouse where 1 inch on the plans is equivalent to 5 inches on the actual dollhouse.
If the house is to be 32.5 inches tall, the height be on the plans will be one-fifth of the actual dollhouse. This will be:
= 1/5 × 32.5
= 6.5 inches
Answer:
Step-by-step explanation:
log3^(2x+3) = log243
(2x+3)log3 = log243
2x+3 = log243/log3
2x = (log243/log3)-3
x = [(log243/log3)-3]/2
x = (5-3)/2
x = 2/2
x = 1
Check:
3^2(1)+3 = 243
3^2+3 = 243
3^5 = 243
3×3×3×3×3 = 243
9×9×3 = 243
81×3 = 243
243 = 243
Answer:
Step-by-step explanation:
6^2+B^2=3^2X5
36+b^2=9x5
b^2=9
b=3
We add all these mixed numbers together:
1 1/2 + 2 3/4 + 2 1/3
It will be easier to convert the mixed numbers into improper fractions:
3/2 + 11/4 + 7/3
Now we have to find the common denominator which is 12:
18/12 + 33/12 + 28/12 = 79/12 = 6 7/12
The answer is 6 7/12 hours.
It is impossible to list the set of rational numbers using the roster method because the set of rational numbers is uncountable/inumerable.
There is no way to list all the members of the set of rational numbers.
