We know that

[volume of a cone]=pi*r²*h/3
r=2 in
h=6 in
[volume of a cone]=pi*2²*6/3------> 25.12 in³

1 ft³---------> 1728 in³
then
X------------> 25.12 in³
X=25.12/1728-----> x=0.014537 ft³

if 1 ft³--------------------> cost $5
0.014537 ft³-----------> X
X=0.014537*5-----> x=0.073

the answer is
<span>the total value of the substance in the container is $0.07</span>

"If a number divided by 4 leaves remainder 2 or 3", then which one is the correct statement 'n why?
Hoochie [10]

Answer:

As the number is a prime number. Therefore, option 'c' is true.

Step-by-step explanation:

Let us take the number 7 and divide it by 4

\frac{7}{4}

We know that

  • Quotient\frac{Remainder}{Divisor}

as

\frac{7}{4}=1\frac{3}{4}

so the remainder is 3.      ∵ Quotient\frac{Remainder}{Divisor}

As 7 is a prime number, and when we divide the prime number 7 by 4, we get the remainder 3.

Thus, the number is a prime number. Therefore, option 'c' is true.

Please help me with this question
Natali5045456 [20]
Again, In this question too you need to substitute the given variable values into the original expressions. Here, "x" is given as a value of "12" and the variable of "y" is given as as value of "2". A single variable of "x" in the numerator is given in the expression. On the denominator the variable of "y" with a value of "2" is multiplied by a numbered value of "3". So, now showing this by the help of LaTeX.

\mathbf{Since, \: x = 12, \: y = 2}

\mathbf{\therefore \quad \dfrac{12}{3 \times 2}}

\mathbf{\therefore \quad \dfrac{12}{6}}

\mathbf{2}

\boxed{\mathbf{\underline{\therefore \quad Final \: \: Answer \: \: is: \: B) \: 2}}}

Hope it helps.

A right triangular prism is shown.What is the lateral surface area?
makkiz [27]

The general formula for the lateral surface area of a right prism is

L = ph

where p represents the perimeter of the base and h represents the height of the prism.

In our case, the perimeter is the sum of the bases.

p = 5 + 5.6 + 2.5 = 13.1 cm

now, the height of the prism is 8 cm

then L = 13.1 cm x 8 cm = 104.8cm^2
