Answer:
h = 20 cm
Step-by-step explanation:
The volume (V) of a square based prism is
V = area of base × h ( h is the height )
area of square base = 9 × 9 = 81 cm²
Hence
81h = 1620 ← equation to be solved
Divide both sides by 81
h = 20 cm
X-15=3 so first thing to do is to isolate the x. To do this, you do the following:
x-15=3
+15+15
------------
x= 18
18-15=3
Answer: 6
Step-by-step explanation: [▲x4]+[6x3]=6[4+3
6[4+3=42 so if [6x3]=18 then [▲x4] needs to be 24 (24+18=42) ▲=6 as 6x4=24+18=42 (6[4+3)!
<span>The answer is 7.0. When you want to round to the nearest tenth, you need to leave only one decimal. The second decimal is 5. So, the first decimal will be rounded to the first bigger number. In this case 6.95, the first decimal number 9 will increase to 10 which means that the number 6.95 will be rounded to a whole number: 6.95 = 7.0</span>
Answer:
65
Step-by-step explanation:
Hi, what you do first is:
P (which stands for perimeter)= L + W + L + W (L stands for length and W stands for width)
P= 16in + 12in + 12in + 25in
P= 28in + 37in (I added 16 to 12 and 12 to 25)
P= 65in.
