Answer:
768 m^2
Step-by-step explanation:
<u>Separate the shapes</u>
We can first separate the triangular pyramid from the rectangular prism.
We can calculate them separately.
<u>Calculate</u>
The volume of the triangular pyramid is the base multiplied by the height divided by 3. The base of the pyramid has the same base as the prism so:
8 * 8 = 64
Then we need the height which is 6 so:
64 * 6/3 = 64 * 2 = 128 m^2
Then we calculate the volum of the prism; the formula for that side times side time side:
8 * 8 * 10 = 640 m^2
The total volume is them added up:
128 + 640 = 768 m^2
Answer:
Make x 0 and y 3
Step-by-step explanation:
0 multiplied by 2 is 0
-3 multiplied by 3 is -9
0-9 = -9
Answer:
x = 3.25
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
...and is the order of operation.
First, subtract 3 from both sides of the equation:
4x + 3 = 16
4x + 3 (-3) = 16 (-3)
4x = 16 -3
4x = 13
Next, dvide 4 from both sides:
(4x)/4 = (13)/4
x = 13/4
x = 3.25
x = 3.25 is your answer.
