Answer:

$y=1.94x$

13 glue sticks cost $25.22.

Step-by-step explanation:

4 blue sticks cost $7.76, this means that one glue stick costs

$7.76/4 = $1.94.

Let $y$ be the cost of the glue sticks, and $x$ be the number of glue sticks; then

$\boxed{y=1.94x}$

We can use this equation to find the cost of 13 glue sticks; we just put $x=13\$ into our equation and it gives:

$y=1.94(13)=25.22$

So 13 glue sticks cost $25.22.

Answer:

°F = 9/5 (°K - 273) + 32

Step-by-step explanation:

°C = °K - 273

°F = 9/5 °C + 32

Put the 1st formula in the 2nd

°F = 9/5 (°K - 273) + 32

Tony wants to plant no more than 400 acres of corn and soybeans. He earns $300 per acre of soybeans and $200 for corn. He needs

inna [77]

In this item, we let x be the number of corns and Y represent soybeans. The sum of these variables is 400. This is represented by the equation,
x + y = 400
The amount that needs to be earn by Tony is then represented by,
200x + 300y ≥ $60,000

In the adjoining figure , AB = 6 , BC = 8 , <img src="https://tex.z-dn.net/?f=%20%5Cangle" id="TexFormula1" title=" \angle" alt=

loris [4]

Here we are given with a triangle with smaller triangles formed due to the altitude on AC. Given:

AB = 6
BC = 8
<ABC = 90°
BD ⊥ AC
<ABD = $\theta$

We have to find the value for sin $\theta$

So, Let's start solving....

In ∆ADB and ∆ABC,

<A = <A (common)
<ABC = <ADB (90°)

So, ∆ADB ~ ∆ABC (By AA similarity)

The corresponding sides will be:

$\sf{ \dfrac{AD}{AB} = \dfrac{AB}{AC} }$

We know the value of AB and to find AC, we can use Pythagoras theoram that is:

AC = √6² + 8²

AC = 10

Coming back to the relation,

$\sf{ \dfrac{AD}{6} = \dfrac{6}{10} }$

$\sf{AD = \dfrac{6 \times 6}{10} = 3.6}$

In ∆ADB, we have to find sin $\theta$ which is given by perpendicular/base:

$\sf{\sin( \theta) = \dfrac{AD}{AB} }$

Plugging the values of AD and AB,

$\sf{\sin( \theta) = \dfrac{3.6}{6} }$

Simplifying,

$\sf{ \sin( \theta) = \dfrac{3}{5} = \boxed{ \red{0.6}}}$

And this is our final answer.....
