Answer:

To compute 1.92 divided by 6 you can multiply 1.92 by 100, compute the division and finally, divide the result by 100. So, 1.92*100 = 192, which can be represented as 18 tenths and 12 ones. This representation is convenient because both 18 and 12 are multiples of 6. Then, dividing 18 tenths by 6 we get 3 tenths (30), and dividing 12 ones by 6 we get 2 ones (2). The addition of the results of these partial divisions is 30 + 2 = 32, which is the result of 192/6. To get 1.92/6 we need to divide 32 by 100, which is 0.32, and that's the result of 1.92/6.

Pls help with this problem
madam [21]

Step-by-step explanation:

every triangle inscribed into a circle with the baseline being a diameter of the circle must be a right-angled triangle.

therefore,

angle XVY = 90°.

for VY we can use Pythagoras

c² = a² + b²

with c being the Hypotenuse (the line opposite of the 90° angle, in our case XY).

XY = 2×ZY = 2×17 = 34.

so,

34² = 30² + VY²

VY² = 34² - 30² = 1156 - 900 = 256

VY = 16

A club is making posters to raise money. The printer charges a base fee of $270 and $2 per poster for supplies. A person sells e
sesenic [268]

<u>Answer:</u>

He must sell 190 posters make a profit of $300.

<u>Explanation: </u>

Given:

Base fee= $270  

Fee for supplies= $2

Cost of poster=$5

To find:

The number of posters to be sold to get a profit of $300=?

Solution:

Let the number of posters sold be n.

Now, we know that,

profit = selling price – cost price

$ 300 = $ 5 for each poster – ( $ 270 base fee + $ 2 for each poster)

300 = 5 x n – (270 + 2 x n)  

300 = 5n – 270 – 2n  

5n – 2n = 300 + 270  

3n = 570  

n=\frac{570}{3}

n = 190

Another way of finding Surface Area is

  1. SA= 2LW+2LH+2HW

L= Length

W= Width

H= Height

the answer, and explained, would be this

2. SA= 2(12)(10)+2(12)(16)+2 (10)(16)

(<em>multiply</em>)

3. SA= 240 + 384 + 320

(<em>add</em>)

<em>The</em><em> </em><em>answer</em><em> </em><em>is</em><em>.</em><em>.</em><em> </em>

<em><u>SA</u></em><em><u>=</u></em><em><u>944ft3</u></em><em><u> </u></em>
