Answer:

The correct answer is option B. 4√3/3

Step-by-step explanation:

Points to remember

If a right angled triangle with with angles 30°, 60° and 90° then the sides are in the ratio 1 :√3 : 2

To find the value of y

From the figure we can see two right angled triangle.

From the figure we get height 'h' of large triangle is written by,

h : base : 8 = 1 : √3 : 2

Therefore h = 8/2 = 4

Also we can write,

y : h : hypotenuse of small triangle = 1 : √3 : 2

y : 4 : hypotenuse = 1 : √3 : 2

Therefore y = 4/√3 = 4√3/3

The correct answer is option B. 4√3/3

HELP IM DOIN A MATH TEST AND IM STUCK!!!!! Tim knows the volume In bass area of a wooden chest that is in the shape of a rectang

ki77a [65]

Answer:

Height is 1 1/24 unit.

Step-by-step explanation:

Given:

volume = 5/24 unit³

base area = 1/5 unit²

Rectangular prism:

volume = length * width * height

base area = length * width

Volume = base area * height

height = volume / base area

h = 5/24 ÷ 1/5

h = 5/24 * 5/1 = 5*5 /24*1 = 25/24 = 1 1/24 unit

How do defined terms and undefined terms relate to each other ?

dalvyx [7]

In geometry, definitions are formed using known words or terms to describe a new word. There are three words in geometry that are not formally defined. These three undefined terms are point, line and plane. Undefined terms have not been defined, and defined are answered. They are terms that have a relationship with the point od discussion. :)

What is 1/7 divided by 252 ?

miskamm [114]

Answer:

In decimal form: $0.00056689342$ (If wanted to round to nearest thousandth, $0.001$ )

In fraction form: $\frac{1}{1764}$ or $\frac{28344671}{50000000000}$

Step-by-step explanation:

$\frac{1}{7}\div \:252=\frac{1}{1764}$

$\mathrm{Convert\:element\:to\:fraction}:\quad \:252=\frac{252}{1}\\=\frac{1}{7}\div \frac{252}{1}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}\\=\frac{1}{7}\times \frac{1}{252}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}\\=\frac{1\times \:1}{7\times \:252}$

$\mathrm{Multiply\:the\:numbers:}\:1\times \:1=1\\=\frac{1}{7\times \:252}$

$\mathrm{Multiply\:the\:numbers:}\:7\times \:252=1764\\=\frac{1}{1764}$

Hopes this helps you!

Have a wonderful night!

Happy Monday!
