Answer:
Volume: 864
Surface Area: 684
Step-by-step explanation:
Volume:
Surface-Area: (Pretty Self-explanatory)
1. Triangles - 12 * 9 = 108 (You don't need to divide it by two, just leave it as is because there are two of these triangles.)
2. Base - 16 * 9 = 144
3. Height/Base - 12 * 16 = 192
4. 15 * 16 = 240
192 + 144 + 108 + 240 = 444
The Surface Area is 684.
Answer:
12
Step-by-step explanation:
With PEMDAS you could know to do parentheses FIRST
6 x (10 - 2^3)
6 x (2)
12
Answer:
Step-by-step explanation:
17 ÷ 2 = 8.5
8.5 as a mixed number is .
Answer:
3663
Step-by-step explanation:
The first multiple of 11 between 100 and 300 is 110 and the last multiple is 297. Total number of multiples is (297-110)=(n-1)*11, n=18
Sum of these multiples is (First term + Last term)*(n)/2=3663
Let r be the interest rate. Then:
1000(1+r/4)^4=1500
(1+r/4)^4=1.5
ln (1+r/4)^4= ln 1.5
4 ln (1+r/4)=ln 1.5
ln (1+r/4)=0.10136627702704109549450327886609
1+r/4=e^0.10136627702704109549450327886609=1.1066819197003215924087902734403
r/4=0.1066819197003215924087902734403
r=0.42672767880128636963516109376133 or 42.67%, compounded quarterly. ☺☺☺☺
