Answer:

$\sqrt[3]{17}= 2.57128=257128$ × $10^{-5}$

Step-by-step explanation:

We need to find: $\sqrt[3]{17}$ in decimals. To do this, we are going to need the help of a calculator. After plugging the values, we get that:

$\sqrt[3]{17}= 2.57128 = 257128$ × $10^{-5}$

In this case, I just considered 5 significant figures!

If you were to rotate the flag to the right you will see that the inside seams of the shadow box are the same length as the edges of the folded flag. Meaning that if we were to just consider the length measurements of the folded flag then the flag would fit. However, we are also given the degree of which the point of the flag is folded, so we need to make sure that matches with the degree angle of the shadow box. The angles are the same therefore the folded flag should fit perfectly into the shadow box.

What percentage of 85 is 10

Hi there!

~

What percentage of 85 is 10?

$= 11.76$

(These are just some tips)

↓↓↓

Take the number and multiple it by 85. Then multiply that by . 01.

To calculate 10 percent of a number, simply divide it by 10 or move the decimal point one place to the left. For example, 10 percent of 230 is 230 divided by 10, or 23.

❀Hope this helped you!❀

Is anyone good at math and can help with this, or at least the first one and explain how to do it?

now, bear in mind that all these ones are lines, and to graph a line all you need is two points, so let's pick a couple of random values for say "x" and let's see what we get for "y" and that's our x,y point.

$9x+4y=-16\implies \stackrel{\textit{using x = 0}~\hfill }{9(0)+4y=-16}\implies 4y=-16 \\\\\\ y=\cfrac{-16}{4}\implies y=-4~\hspace{10em}(0~~,~~-4) \\\\[-0.35em] ~\dotfill\\\\ 9x+4y=-16\implies \stackrel{\textit{using x = -4}~\hfill }{9(-4)+4y=-16}\implies -36+4y=-16 \\\\\\ 4y=20\implies y = \cfrac{20}{4}\implies y = 5~\hspace{10em}(-4~~,~~5)$

check the red line in the picture below.

$5x+2y=8\implies \stackrel{\textit{using x = 0}~\hfill }{5(0)+2y=8}\implies 2y=8\implies y=\cfrac{8}{2}\implies y=4 \\\\\\ ~\hspace{10em}~\hspace{10em}(0~~,~~4) \\\\\\ 5x+2y=8\implies \stackrel{\textit{using x = 4}~\hfill }{5(4)+2y=8}\implies 20+2y=8\implies 2y=-12 \\\\\\ y=\cfrac{-12}{2}\implies y=-6~\hspace{10em}(4~~,~~-6)$

check the blue line in the picture below.
