Cylinders are 3D figures, as they are solids with volume and take up space.

2D figures are flat figures that you can draw, like a square or circle.

1D figures are actually just a line, a segment, or a point, etc.

Answer:

B. 7 inches

Step-by-step explanation:

The surface area of a cube is denoted by: A = 6s², where s is the side length.

Here, we know that A = 294 in², so plug this into the equation to solve for s:

A = 6s²

294 = 6s²

s² = 49

s = √49 = 7

The answer is thus B, 7 inches.

A business is owned by 3 people. Mrs. Applegate owns

Bezzdna [24]

Given:

Mrs. Applegate owns $\dfrac{3}{19}$ of the business.

Mrs. Brown owns 3 times as much as Mrs. Charles.

To find:

The fractional part of the business that Mrs. Brown owns.

Solution:

Let Mrs. Charles owns x part of business.

Mrs. Brown owns 3 times as much as Mrs. Charles.

Mrs. Brown owns = 3x part of business.

Mrs. Applegate owns $=\dfrac{3}{19}$ of the business.

$x+3x+\dfrac{3}{19}=1$

$4x=1-\dfrac{3}{19}$

$4x=\dfrac{19-3}{19}$

$4x=\dfrac{16}{19}$

Divide both sides by 4.

$x=\dfrac{16}{4\times 19}$

$x=\dfrac{4}{19}$

Now,

Mrs. Brown owns $=3\times x$

$=3\times \dfrac{4}{19}$

$=\dfrac{12}{19}$

Therefore, Mrs. Brown owns $\dfrac{12}{19}$ of the business.

Mia paints interior walls at a rate of 12\dfrac{\text{m}^2}{\text{h}}12 h m 2 12, start fraction, m, start superscript, 2, end

Travka [436]

Answer:

$2,000\ \frac{cm^{2}}{min}$

Step-by-step explanation:

<u><em>The correct question is</em></u>

Mia paints interior walls at a rate of 12 m^2/h. At what rate does she paint in cm^2/min?

Remember that

$1\ m=100\ cm$

$1\ h=60\ min$

Convert m^2/h to cm^2/min

substitute the values

$12\ \frac{m^{2}}{h}=12\frac{(100)^{2}}{60}=2,000\ \frac{cm^{2}}{min}$
