Answer:

x=14√3

y= 28

Step-by-step explanation:

Below i've attached a 30-60-90 triangle

we can see from the picture that the side length opposite from 30 is just a

which means at a=14

The hyp is equal to 2a= 28

and x is equal to 14√3

Order the following numbers from least to greatest.

zaharov [31]

Answer:

-5.5 $-\sqrt{20}$ $\sqrt4$ $\frac{22}{7}$ 4.5

Step-by-step explanation:

Given:

The numbers to order from least to greatest is given as:

$-5.5, 4.5, 22/7,\sqrt4,-\sqrt{20}$

In order to compare these numbers, we have to convert them in same form.

Let us simplify each number in decimal form.

$-5.5 = -5.5\\\\4.5=4.5\\\\\frac{22}{7}=3.14\\\\\sqrt4=2\\\\-\sqrt{20}=-\sqrt{5\times 2^2}=-2\sqrt5=-4.47$

So, the least number is one which has the largest value with a negative sign.

Here, -5.5 is the least number.

The next smallest number is -4.47. So, $-\sqrt{20}$

The next smallest number is 2. So, $\sqrt4$

The next smallest number is 3.14. So, $\frac{22}{7}$

The greatest number is 4.5.

Therefore, the order from the least to greatest is:

-5.5 < $-\sqrt{20}$ < $\sqrt4$ < $\frac{22}{7}$ < 4.5

Write an equation that can be used to solve the problem. Then answer the question asked. A group of college students are volunte

svp [43]

Answer:

Required equation : $\frac{1}{t}=\frac{1}{3}+\frac{1}{9}$

Together they can paint the same room in 2.25 hours or 2 hours 15 minutes.

Step-by-step explanation:

It is given that Dale Horton can paint a certain room in 3 hours.

One hour woks of Dale Horton = 1/3

Kathy Garcia can paint the same room in 9 hours.

One hour woks of Kathy Garcia = 1/9

Let together they can paint the same room in t hours.

One hour woks of both = 1/t

$\frac{1}{t}=\frac{1}{3}+\frac{1}{9}$

$\frac{1}{t}=\frac{3+1}{9}$

$\frac{1}{t}=\frac{4}{9}$

After reciprocal we get

$\frac{t}{1}=\frac{9}{4}$

$t=2.25$

1 hour = 60 minutes.

0.25 hour = 15 minutes.

Therefore, together they can paint the same room in 2.25 hours or 2 hours 15 minutes.
