A tetrahedron is a pyramid with a triangular base. Find the volume of the tetrahedron.
L = 3 in W = 4 in H = 11 in
Answer:
Tetrahedron generally known as triangular pyramid consists of 4 triangular faces, 6 edges and 4 vertices. The base of the tetrahedron is a triangle. All the vertices have the same atom that is bonded to the central metal atom which lies in the centre of the tetrahedron. We take as an example to see how the atoms actually bond in tetrahedron. It is quite visible from the image that 4 O-atoms lies on all the 4 vertices and 1 Si-atom lie in the centre.

Christian made smoothies by mixing 2.25 liters of orange juice, 4.75 liters of pineapple juice, and 2.5 liters of grape juice. He then poured equal amounts of mix into 5 different containers for his friends. About how much smoothie did Christian pour in to each container? Please tell me how you got the answer!!!
Answer: He poured about 2 liters into each cup.
Step-by-step explanation: First add 4.75 , 2.25 , and 2.50 which equals 9.5. Divide 5 which then equals 1.9 but since its an estimate you could say 2.

6x + y = 15
-7x - 2y = -10
Answer: x = 4 y=-9
Step-by-step explanation:
Answer:
x = 4
y = -9
Step-by-step explanation:
Isolate a variable from one of the equations ( I chose the first equations cuz it's easy): 6x + y = 15 will be y = 15 - 6x
Substitute the above equation in the place of y in the second equations:
-7x -2(15 - 6x) = -10
-7x -30 + 12x = -10
-30 + 5x = -10
5x = 20
x = 4
To find y-value, substitute the x-value gotten in any equation:
y = 15 - 6(4)
y = 15 - 24
y = -9
Hope this helps!

What is Proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Sarah used 10 gallons of gasoline to drive 240 miles.
let in 324 miles, x gallons of Gasoline is used.
Now, using proportion we have
10 / 240 = x / 324
3240 = 240 x
x = 3240 / 240
x = 324 / 24
x = 13.5 miles
