The answer is 3x-x :)

You just simplify the expression, (4x^2-x^2) - (x- (-2x))

In how many years will $7000 yield an interest of $4620 at 22% simple interest?
meriva

Answer:

3 Years

Step-by-step explanation:

7000*22% = 1540

4620/1540 = 3

1540 = the yearly interest

so it will take 3 years of $1540 of interest to get $4620.

Normally you would also have to take into account the interest plus the base varible but since it specifically says 7000 it makes it a simple problem.

hope this helped

Choose the correct simplification of x to the 3rd power over y to the 5th power all raised to the 2nd power.

\left( \cfrac{x^3}{y^5} \right)^2=\cfrac{(x^3)^2}{(y^5)^2}=\cfrac{x^{3*2}}{y^{5*2}}=\cfrac{x^{6}}{y^{10}}

A circle is dialated with a scale factor of 2/3. what is the area of the new circle if the area of the original circle is 45 squ
Sveta_85 [38]
Original Circle Area = 45

A = pi * r^2

Plug in what we know:

45 = 3.14 * r^2

Divide 3.14 to both sides:

14.3312102 = r^2

Find the square root of both sides:

r = 3.78565849

Find 2/3 of this:

2/3 * 3.78565849 = 2.52377233

So this is the radius of the newly dilated circle.

A = pi * r^2

A = 3.14 * 2.52377233^2

A = 3.14 * 6.36942677

A = 20

So the area of the newly dilated circle is 20 square inches.

How much grain can a cylinder of the radius 4inches and height of 11inches hold?
strojnjashka [21]

Answer:

553.0 in³

Step-by-step explanation:

(please see attached for reference)

Assuming you are asked to find the volume,

the volume of the cylinder is given by

V = πr²h

where,

π=3.142

r = given as 4 inches

h = given as 11 inches

Substituting these values into the formula,

V = πr²h

V = 3.142 x 4² x 11

= 552.99

= 553.0 in³ (rounded to nearest tenth)
