Answer:

Step-by-step explanation:

using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$ , then

$\sqrt{12}$

= $\sqrt{4(3)}$

= $\sqrt{4}$ × $\sqrt{3}$

= 2 $\sqrt{3}$

Then

$\sqrt{144}$ + 18 $\sqrt{12}$ - 5 $\sqrt{64}$

= 12 + 18(2 $\sqrt{3}$ ) - 5(8)

= 12 + 36 $\sqrt{3}$ - 40

= - 28 + 36 $\sqrt{3}$

Maritza is baking cookies to bring to school and share with her friends on her birthday. The recipe requires 3 eggs for every 2

Crazy boy [7]

No, because if you work with fraction and do $\frac{3}{2}$ (3 eggs for every 2 cups) then you would be multiplying 3x4 and now you have tot do that to the demominator so she would need 8 cups of sugar

The volume of ice-cream in the cone is half the volume of the cone. The cone has a 3 cm radius and

zhannawk [14.2K]

Answer:

h = 5 cm

Step-by-step explanation:

Given that,

The volume of ice-cream in the cone is half the volume of the cone.

Volume of cone is given by :

$V_c=\dfrac{1}{3}\pi r^2h$

r is radius of cone, r = 3 cm

h is height of cone, h = 6 cm

So,

$V_c=\dfrac{1}{3}\pi (3)^2\times 6\\\\V_c=18\pi\ cm^3$

Let $V_i$ is the volume of icecream in the cone. So,

$V_i=\dfrac{18\pi}{2}=9\pi\ cm^3$

Let H be the depth of the icecream.

Two triangles formed by the cone and the icecream will be similiar. SO,

$\dfrac{H}{6}=\dfrac{r}{3}\\\\r=\dfrac{H}{2}$

So, volume of icecream in the cone is :

$V_c=\dfrac{1}{3}\pi (\dfrac{h}{2})^2(\dfrac{h}{3})\\\\9\pi=\dfrac{h^3}{12}\pi\\\\h^3=108\\\\h=4.76\ cm$

h = 5 cm

So, the depth of the ice-cream is 5 cm.

What is the equation of the line with a slope of 1/4 and a y-intercept of 2?

ELEN [110]

Equation of the line in slope intercept form is

y = 1/4 * x + 5. Slope is 1/4. Intercept is 5.

If x= 4, y = (1/4)*4 + 5 = 6.

The point (4,6) lies on the line.

Equation of the line in point slope form is

(y - y1)= m * (x - x1) where m is slope & (x1,y1) is point on the line.

Substituting slope m= 1/4 & point (4,6),

Equation of the line in point-slope form is:

(y - 6) = 1/4 * (x - 4).
