Answer:

The volume of ice cream cone is 66 cubic inch.

Step-by-step explanation:

Diameter of ice cream cone is 6 inches

Height of the cone is 7 inches

The volume of a cone shaped object is given by :

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

Substituting all the values in above formula as:

$V=\dfrac{1}{3}\times \dfrac{22}{7}\times 3^2\times 7\\\\V=66\ \text{inches}^3$

So, the volume of ice cream cone is 66 cubic inch.

3.8*10 to the 9th power divided by 4*10 to the 2nd power

user100 [1]

Answer:

$9.5\times 10^{6}$

Step-by-step explanation:

1. Divide the coefficients and the exponentials separately

$\dfrac{3.8 \times 10^{9}}{4 \times 10^{2}} = \dfrac{3.8}{4} \times \dfrac{10^{9}}{10^{2}}$

2. Divide the coefficients

$\dfrac{3.8}{4} = 0.95$

3. Divide the exponentials

Subtract the exponent in the denominator from the exponent in the numerator.

$\dfrac{10^{9}}{10^{2}} = 10^{(9 - 2)} = 10 ^{7}$

4. Re-join the new coefficient and the new exponential

$\dfrac{3.8 \times 10^{9}}{4 \times 10^{2}} = 0.95 \times 10^{7}$

5. Put the new number into standard form

The number before the power of 10 must be greater than or equal to one and less than 10.

Multiply the answer by 10/10.

$(0.95 \times 10^{7}) \times \dfrac{10}{10} = (0.95\times10) \times \dfrac{10^{7}}{10} = \mathbf{9.5\times 10^{6}}$

Y <= - 1/3 * x + 2; y > 2x - 3 linear inequalities

marishachu [46]

Step-by-step explanation:

Given

Inequalities are $y\leq -\dfrac{1}{3}x+2$ and $y>2x-3$

Take the inequality as two equations to get the intersection point

$y=-\dfrac{1}{3}x+2\ and\ y=2x-3$

Equate the value of y

$\Rightarrow -\dfrac{1}{3}x+2=2x-3\\\Rightarrow 5=\dfrac{7x}{3}\\\\\Rightarrow x=\dfrac{15}{7}$

$\therefore y=1.286$

The common region gives the required regions for inequalities.
