The answer is 1. 9 over 9 is a whole, which is one. 1 to the second power is 1. 1 to the 7th power is 1. No matter how many exponents you put on 1, it will always stay one. So the answer is 1.

Congruent triangles are all the same. Given that the faces of a triangular pyramid are congruent then all its faces are the same. It is also good to note that this pyramid has 4 faces. Given that the surface area of the pyramid is 372m^2, the area of one face will be:
area=(total area)/(number of faces)
=372/4
=93 m^2

Is this right? someone please help :)

Answer:

v = m/d

Step-by-step explanation:

d = m/v

Multiply each side by v

d*v = m/v * v

dv = m

Now divide each side by d

dv/d = m/d

v = m/d

Isabella spent $49 for 7 bracelets. Each bracelet cost the same amount.
n200080 [17]
To answer this question, we first have to set up an equation with variables.
We can use "x" to represent the cost of each bracelet.

Equation: number of bracelets bought × cost of each bracelet = total cost

Number of bracelets bought: 7
Total Cost: 49

Using this information, we can fill in the equation and solve for x.

7x = 49

To isolate x, divide both sides by 7.

x = 7

Since x equals 7, we now know that each bracelet cost $7.
