Q: can you find the volume of the tank based on the opposite sides as the bases.

This one was a tricky one lol.

To find volume you need a formula:

Formula for volume varies on the shape of the object.

Cube = a 3a is the side length

Rectangular prism = a * b * ca, b, c are the length, width, and height

Cylinder = π * r 2 * hr is the radius of the circular baseh is the height

for this one you would need the Rectangular prism formula.

A: No you cannot find the volume because you need length, width, and height to figure out the volume of the rectangular prism.

Hope this helped! :)

Given that PQRS is a square, find x and y.

Dovator [93]

Every angle of a square equals 90 degrees.

2x - 4 = 90 3y + 6 = 90
2x = 90 + 4 3y = 90 - 6
2x = 94 3y = 84
x = 94/2 y = 84/3
x = 47 y = 28

so x = 47 and y = 28

Answer:

The range includes all numbers from 5 to 12.5.

Step-by-step explanation:

The range is along y- axis and the domain is along x- axis.

Range is given in heights and domain is given in time seconds.

It can depicted that for t= 0 secs the ball is at 5 feet and so on .

Therefore the range is given by numbers from 5 to 12.5.

Whereas the domain is given by numbers 0 t0 8.5 seconds

Sofia takes 10mg of a medicine whose concentration in blood decreases by a factor of one half every day. Let t be the number of

adelina 88 [10]

Answer:

$L = 10(\frac{1}{2} )^{t-4}$

Step-by-step explanation:

If t is the number of days since Sofia took the medication of 10 mg, then the amount of medication in her system after t days will be $S = 10(\frac{1}{2} )^{t}$ .

So, the concentration of medicine in blood decreases by a factor of one half every day.

If we count the number of days from today and Lexi takes 10 mg of the same medicine four days later then the amount of medicine left on her body after t days will be $L = 10(\frac{1}{2} )^{t-4}$ . (Answer)
