Answer:

We need to add 7 pounds of $9.5 premium coffee to make a blend of coffee that $10.

Step-by-step explanation:

Lets take the amount of $9.50 coffee added was $x$ pounds.

The requirement is that the value of 1 pound of resulting mixture of coffee to be $10.

We can use the weighted average value to find the value of the resulting mixture.

⇒ $\frac{(9.5*x)+(11.75*2)}{(x+2)} =10$

= $(9.5*x)+(23.5)=10(x+2)$

= $9.5x+23.5=10x+20$

= $3.5=0.5x$

= $x=7$

So we need to add 7 pounds of $9.5 premium coffee to make a blend of coffee that $10.

Why can't a trapezoid have 4 obtuse angles

In-s [12.5K]

Hello there, and thank you for posting your question here on brainly.

A trapezoid is not possible to have for obtuse because it would look more like a diamond. Also, if it had 4 obtuse angles, it would have 6 sides.

Hope this helped!! ☺♥

The length of the red line segment is 8 and the length of the blue line segment is 4. How long is the major axis of the eclipse?

liraira [26]

The major axis of the eclipse is 12 units long

The given parameters can be represented as:

$Red = 8$

$Blue = 4$

See attachment for illustration

To solve this question, we make use of the following theorem

The distance between a point and the foci sums up to the major axis

This translates to:

$Major\ axis = Red + Blue$

$Major\ axis = 8 + 4$

$Major\ axis = 12$

under a dilation, the point (2,6) is moved to (6,18) what is the scale factor of the dilation? enter your answer in the box

Anestetic [448]

<h2>3</h2>

Step-by-step explanation:

The equation of line passing through the two points is $\frac{y-y_{1} }{x-x_{1} }=\frac{y_{2} -y_{1}}{x_{2} -x_{1}}$

When substituted,the equation becomes $\frac{y-6}{x-2}=\frac{18-6}{6-2}$

which when simplified is $y=3\times x$

The line clearly passes through origin.

The distance between two points is $\sqrt{(y_{1}-y_{2} )^{2}+(x_{1}- x_{2} )^{2}}$

Distance between origin and $(2,6)$ is $\sqrt{40}$ .

Distance between origin and $(6,18)$ is $\sqrt{360}$

Scale factor is $\frac{distance\text{ }of\text{ }p_{2}\text{ from origin}}{distance \text{ } of \text{ } p_{1}\text{ from origin}}$

So,scale factor is $\frac{\sqrt{360} }{\sqrt{40} }$

which when simplified becomes 3.
