Move all terms that don't contain x to the right side and solve.

x = -1

Subtract 60 on both sides to get -40.

You are left with 40x=-40

Divide both sides by 40 to leave x by itself.

You get x=-1.

Given:

The given figure is a square pyramid.

The side length of the base of the pyramid is 6.6 feet.

The height of the pyramid is 12.672 feet.

We need to determine the volume of the pyramid.

Area of the base:

The area of the base can be determined using the formula,

$A=a^2$

where a is the side length of the base.

Substituting a = 6.6, we get;

$A=6.6^2$

$A=43.56 \ ft^2$

Thus, the area of the base is 43.56 square feet.

Volume of the pyramid:

The volume of the pyramid can be determined using the formula,

$V=\frac{1}{3}Ah$

where A is the area of the base and h is the height of the pyramid.

Substituting A = 43.56 and h = 12.672, we get;

$V=\frac{1}{3}(43.56)(12.672)$

$V=184 \ ft^3$

Thus, the volume of the pyramid is 184 cubic feet.

Debra borrowed $8000 at a rate of 18% compounded semiannually. Assuming she makes no payment, how much will she owe after 9 year

Marina CMI [18]

Answer:

She owe $37736.96 after 9 years .

Step-by-step explanation:

Debra borrowed $8000 at a rate of 18% compounded semiannually

We are supposed to find how much will she owe after 9 years

Principal = 8000

Rate of interest = 18% =0.18

No. of compounds per year = 2

Time = 9 years

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

Substitute the values in the formula :

$A= 8000(1+\frac{0.18}{2})^{2 \times 9}$

A= 37736.96

Hence She owe $37736.96 after 9 years .
