Find volume of triangular pyramid or prism.

Mathematics
2 answers:
Charra [1.4K]4 years ago

Answer:

Yeah, it's a triangular pyramid.

:)

661.5 :)

Step-by-step explanation:

So we know the formula is 1/3*B*H, and the height is 15! That means we have to solve for b!

10.5 * 25.2 = 264.6 Now we divide 264.6/2 to get 132.3.

Now we can use the formula.

132.3 * 15 * 1/3 = 661.5 :)

Customers of a satellite dish company must pay for installation of the dish, and a monthly fee for service. After 6 months, Ryan
FromTheMoon [43]

Cost of installation fee is $120.

Step-by-step explanation:

Let,

Monthly fee = x

Installation fee = y

According to given statement;

6x+y=594   Eqn 1

11x+y=989   Eqn 2

Subtracting Eqn 1 from Eqn 2

(11x+y)-(6x+y)=989-594\\11x+y-6x-y=395\\5x=395\\Dividing\ both\ sides\ by\ 5\\\frac{5x}{5}=\frac{395}{5}\\x=79\\

Putting x=79 in Eqn 1

6(79)+y=594\\474+y=594\\y=594-474\\y=120

Cost of installation fee is $120.

13x−2=<br>  <br>  <br> −<br> 10<br> x<br> −<br> 2<br> −10x−2
Misha Larkins [42]

Answer:

x=0

Step-by-step explanation:

13x-2 = 10x-2

Subtract 10x from each side

13x-10x-2 = 10x-2 -10x

3x-2 = -2

Add 2 for each side

3x-2+2 = -2+2

3x= 0

divide by 3

3x/3 = 0/3

x =0
