Answer:

300, 40, 180, 24

Step-by-step explanation:

This method of multiplication is called the Grid method multiplication where the larger numbers of a multiplication operation are split into a form which is easier to multiply. The split numbers are arranged in a grid and multiplied as shown below:

Here the two numbers are 16 and 34 which are split by (10+6) and (30+4)

We multiply them

(10+6)×(30+4)

=10×30+10×4+6×30+6×4

=300+40+180+24

=544

The partial products are 300, 40, 180, 24

Which statement is true about the circumference of a circle? The circumference is equal to the radius of the circle. The circumf

Irina18 [472]

<h3>The true statement about circumference of a circle is: circumference is found by multiplying Pi by the diameter</h3>

Solution:

The circumference of a circle is given as:

$\text{circumference } = 2 \pi r$

Where,

"r" is the radius of circle

We know that,

$diameter = 2 \times radius\\\\d = 2 \times r\\\\d = 2r$

Thus the circumference can also written as:

$\text{circumference } = 2 \pi r\\\\\text{circumference } = \pi \times d$

Thus, the circumference is found by multiplying Pi by the diameter is correct statement

Please Help!! What is the measure of angle AXB?

Goshia [24]

Answer:

Step-by-step explanation:

Two angles are supplementary when their sum is 180

∠AXB + ∠BXC = 180° {Supplementary angles}

8x + 10 + 2x - 20 = 180

Add the like terms

10x - 10 = 180

10x = 180 + 10

10x = 190

x = 190/10

x = 19°

∠AXB = 8x + 10

= 8 * 19 +10

= 152 + 10

∠AXB = 162

A toy company is considering a cube or sphere-shaped container for packaging a new product. The height of the cube would equal t

Darya [45]

Answer:

Packaging with cube will be more efficient.

Step-by-step explanation:

Given:

A cube and a sphere where the diameter of the sphere is equal to the height of the cube.

Let the height of the cube "x"

Radius of the sphere = $(\frac{x}{2})$

Formula to be used:

Surface area of the cube = $6x^2$ and Surface area of the sphere = $4\pi (r)^2$

Volume of the cube = $x^3$ and Volume of the sphere = $\frac{4\pi r^3}{3}$

We have to compare the ratio of SA and Volumes.

Ratio of SA : Ratio of their volumes :

⇒ $\frac{SA\ of\ cube\ (S_1)}{SA\ of\ sphere\ (S_2)}$ ⇒ $\frac{Volume \ of \ cube\ (V_1)}{Volume\ of\ sphere\ (V_2)}$

⇒ $\frac{6x^2}{4\pi (\frac{x}{2})^2}$ ⇒ $\frac{x^3}{\frac{4 \pi r^3}{3} }$

⇒ $\frac{6x^2}{4\pi (\frac{x^2}{4})}$ ⇒ $\frac{x^3}{\frac{4 \pi (\frac{x}{2})^3}{3} }$

⇒ $\frac{6x^2}{\pi x^2}$ ⇒ $\frac{x^3}{\frac{4 \pi (\frac{x^3}{8})}{3} }$

⇒ $\frac{6}{\pi}$ ⇒ $\frac{6}{\pi}$

⇒ approx $2$ ⇒ approx $2$

⇒ $S_1=2S_2$ ⇒ $V_1=2V_2$

Packaging of the toy with the cube will be more efficient as it has more volume comparatively.
