Answer:
81
Step-by-step explanation:
9 × 3n= 3^7
9×3n= 2187
27n= 2187
n= 2187/27
= 81
Hence n= 81
Answer:
<u>SA = 189 cm^2</u>
Step-by-step explanation:
What you're going to want to do is calculate the surface area of each type of side (triangle or rectangle) then add them up accordingly!
Starting with triangles: area = 1/2 * l * h
So, in this scenario its (1/2) * 6 * 4 , or half of 24, which is 12 cm^2
Since we have two triangular sides, that totals to 24 cm^2.
Then the rectangular sides: area = l*h
so, 5*11 = 55 cm^2
We have three rectangular sides, totalling 165 cm^2
165+24 = 189 cm^2
12 inches equals (or :1) foot; the ratio of inches to feet is 12 inches to one foot 24 inches; the ratio of feet to inches is 2:24. 6 feet equals 2 yards; the ratio of feet to yards is 6:3. 1 yard equals 3 feet; the ratio of yards to feet is 1:3
