Because there are more than 2 lengths for the sides and because the small triangle faces are right angles we will use this formula:

V=(1/2)bhl
which is equivalent to V=Al (A=(1/2)bh and A is Area)

b=12in
h=35in
l=40in

A=(1/2)•12in•35in
A=(1/2)•420in
A=210in^2

V=Al
V=(210in^2)•40in
V=8400in^3

Making your answer D. 8400 inches cubed

Suppose that $1200 is invested at 612%, compounded quarterly. How much is in the account at the end of 5 years?

asambeis [7]

Answer:

$\$1,656.50$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=5\ years\\ P=\$1,200\\ r=6\frac{1}{2}\%=6.5\%=6.5/100=0.065\\n=4$

substitute in the formula above

$A=1,200(1+\frac{0.065}{4})^{4*5}$

$A=1,200(1.01625)^{20}$

$A=\$1,656.50$

What is the volume of the composite figure shown? Use 3.14 for π.

Ivenika [448]

Answer:

25.12

Step-by-step explanation:

the formula of a cone is pi r^2 * h/3

r = radius and h = height

the radius is 2 and the height is 3

and the question says use 3.14 instead of pi so

we have

3.14 * 2^2 * 6/3

2*2 or 2^2 = 4

3.14 * 4 * 6/3

6/3 = 2

3.14 * 4 * 2

4*2 = 8

and 8 * 3.14 is 25.12
