What is 275,609 to the nearest thousand

nasty-shy [4]

There are 6 time zones in the US: Hawaiian, Alaskan, Pacific, Mountain, Central, and Eastern. To figure out the time in different zones start with what you know: It's 10 am in the Eastern zone, and LA is in Pacific time. Now go back to the list and count backwards from Eastern to Pacific: 3. For each different time zone subtract 1 from 10: 10-3=7. In LA it would be C. 7 am :)

Find the value of x to the nearest tenth

lorasvet [3.4K]

Answer:

Look below.

Step-by-step explanation:

Good ol' Pythagorean Theorem.

To find the short side of the larger triangle, we'll use this equation:

$a^{2} +b^{2} =c^{2} \\\\9^2+b^2=10^2\\81+b^2=100\\$

You can solve the rest on your own.

Use the same type of equation for the smaller triangle, except your b would be the hypotenuse, so that equation would look something like this:

$3^2+x^{2} = b^2$

Hope it helped! Also, there seems to be a help video, if you didn't understand this explanation, why don't you go ahead and watch it?

Find the perimeter and area of the figure. Round to the nearest tenth if necessary. 33.7 mm; 108 mm2 33.7 mm; 54 mm2 30.7 mm; 50

Deffense [45]

Answer:

Perimeter: 33.7 mm

Area: 54 mm

Step-by-step explanation:

If you do 12 + 9.7 + 12 you will get the perimeter, and to get the area you would use the formula A = $\frac{1}{2}$ x base x height. Since the base is 12 and the height is 9, you would do 12 x 9 x 0.5 to get 54 mm for the area of the triangle.

How do you answer this equation?<br> 5a - 12 = 48

IgorC [24]

Add 12 to both sides resulting in 5a = 60 and then divide both sides by 5 which results in a = 12 so your answer will be a = 12

Question is in screenshot. Please answer it correctly

fomenos

a) You need to sell 12 or 29 dresses.

b) Any number between 2 and 39 dresses will give a positive profit.

<h3>How many dresses must be sold in order to make a profit of 3000 euros?</h3>

Here we know that the profit, in euros, as a function of the number of dresses sold is:

P(x) = -11*x^2 + 450*x - 800

Now, if you want to find how many dresses you need to sell to have a profit of 3000 euros, then you need to solve:

P(x) = 3000 = -11*x^2 + 450*x - 800

So we need to solve the quadratic equation:

-11x^2 + 450x - 800 - 3000 = 0

-11x^2 + 450x - 3800 = 0

The solutions are given by Bhaskara's formula:

x = (-450 ± √(450^2 - 4*(-3800)*(-11))/2*(-11)

x = (-450 ± 187.9)/(-22)

We have two solutions that give the same profit:

x = (-450 + 187.9)/-22 = 11.9 that can be rounded to 12.
x = (-450 - 187.9)/-22 = 28.99 that can be rounded 29.

Then if you sell either 12 or 29 dresses, you will get a profit of 3000 euros.

b) To make a profit you need to sell more than P = 0, so let's solve that first:

P= 0 = -11*x^2 + 450*x - 800

The solutions are:

x = (-450 ± √(450^2 - 4*(-800)*(-11))/2*(-11)

x = (-450 ± 409)/(-22)

The smaller solution is:

x = (-450 + 409)/-22 = 1.86 that can be rounded to 2.

(because you can't sell 1.86 of a dress)

The other solution is:

x = (-450 - 409)/-22 = 39

So, between 2 and 39 dresses, you will make a profit.
