Two 28 pound blocks of ice = 28 x 2 = 56
56 x 2/3 =112/3=37.33333
we round it to 37. so it's about 37 cones can be made

Write the equation of a circle with center (-2, 0) and area = 64 pi

kozerog [31]

Answer:

The required equation in standard form is $(x+2)^2+y^2=64$

Step-by-step explanation:

The equation of a circle with center (h,k) an radius, r units is given by the formula;

$(x-h)^2+(y-k)^2=r^2$

The given circle has center (-2,0) and radius squared can be calculated from the given area, which is $64\pi$

$\pi r^2=64\pi$

$\implies r^2=64$

We substitute these values into the formula to obtain;

$(x--2)^2+(y-0)^2=64$

We simplify to get;

$(x+2)^2+y^2=64$

If $3800 is invested in a savings account for which interest is compounded

yulyashka [42]

Answer:

Step-by-step explanation:

The formula to use for this is

$A(t)=P(1+\frac{r}{n})^{(n)(t)}$

For us,

A(t) = 4300

P = 3800

n = 4

t = 2

r = ?

Let's fill in what we have then:

$4300=3800(1+\frac{r}{4})^{(4)(2)}$

which simplifies a tiny bit to

$4300=3800(1+\frac{r}{4})^8$

The first thing to do is to divide both sides by 3800 to get

$\frac{4300}{3800}=(1+\frac{r}{4})^8$

Now take the 8th root of both sides (on your calculator, of course!) to get

$1.01557174=1+\frac{r}{4}$

Now subtract 1 from both sides to get

$.01557174=\frac{r}{4}$

And multiply both sides by 4 to get

.0622869598 = r

Multiply by 100 to get the rate as a percentage. It rounds to

r = 6.23%
