Answer:

T=(total cost)

T=1.084x

Step-by-step explanation:

8.4% *x can be rewritten as 0.084x

Then you have 100% of x, the original cost, which is x

x+0.084x= 1.084x

Thus, the total cost is 1.084x

What is the ratio of the volume of Cylinder A to the volume of Cylinder B?

erastovalidia [21]

Answer:

The ratio of volume of Cylinder A to the volume of Cylinder B is 18:25.

Step-by-step explanation:

Dimension of cylinder A,

Radius is 3 units and height is 4 units.

Dimension of cylinder B,

Radius is 5 units and height is 2 units.

The volume of a cylinder is given by :

$V=\pi r^2 h$

For cylinder A to B,

$\dfrac{V_A}{V_B}=(\dfrac{r_A}{r_B})^2\times \dfrac{h_A}{h_B}\\\\\dfrac{V_A}{V_B}=(\dfrac{3}{5})^2\times \dfrac{4}{2}\\\\\dfrac{V_A}{V_B}= \dfrac{18}{25}$

So, the ratio of volume of Cylinder A to the volume of Cylinder B is 18:25.

1/3 + 1/4 + 1/6<br> PLEASE SHOW WORK, thank you

Dovator [93]

Answer:

3/4

Step-by-step explanation:

1/3 + 1/4 + 1/6

notice that the denominators consists of the numbers 3, 4 and 6 and that the lowest common multiple for all 3 numbers is 12, hence all these fractions can be expressed with a denominator of 12

i.e

1/3 = 4/12

1/4 = 3/12

1/6 = 2/12

hence,

1/3 + 1/4 + 1/6

= 4/12 + 3/12 + 2/12

= (4+3+2) / 12

= 9/12 (simply)

= 3/4
