Just has to be greater than or equal to 0... w and t can never be negative since taking the square root of a negative number yields an imaginary number which would mean imaginary current. Also the question states that w can't be zero but if T is zero than the current will be zero.

Answer:
9
Step-by-step explanation:
let the number
=
x
then 4 times the number
=
4
x
and 4 times the number increased by 15
=
4
x
+
15
also 6 times the number
=
6
x
and 3 less than 6 times the number
=
6
x
−
3
equating the two expressions gives the equation
4
x
+

←
solve for x
subtract 6x from both sides

subtract 15 from both sides

divide both sides by

Answer:
300 in.³
Step-by-step explanation:
We find the volume of 1 prism and multiply it by 2.
V = BH
where V = volume of prism, B = area of the base of the prism, H = height of the prism
V = ½bh × H
V = ½(5 in.)(6 in.) × 10 in.
V = 150 in.³
That is the volume of one triangular prism. Now we multiply it by 2.
volume = 2 × 150 in.³ = 300 in.³
Hello there,
Okay well first we right down what we already know:
- volume of 2,355 cubic inches
- the height is 10 inches
Now we write down the equation for the volume of a cone: V = πr²
- lets plug in what we know into the equation
2,355 = πr²
- now we simplify to solve for r
2,355 / 10/3 = 706.5 = πr²
706.5/π = r²= 224.89
- now since its r² we take the square root of 224.89
r = 15 inches
- for diameter we multiply 15 by 2
diameter = 30 inches
Hope I helped,
Amna
