Katy keeps chickens. For every one white egg she gets five brown eggs.

1 answer:

7 0

You need to split 30 to the ratio of 1:5 so you add 1 and 5 to get 6
You then divide 30 by 6 to get 5
She gets 5 white eggs and (5*5) 25 brown eggs

If you meant to write y=23x-4 then none of the lines are perpendicular.

I suspect you intended y=2/3x-4, then line D, y=-3/2x-4 is perpendicular.

For any line y=mx+b, you have to "invert" m to get a perpendicular line. Inverting in this case means: flip numerator and denominator and add a minus sign.

So 2/3 becomes -3/2, hence answer D.

The 'inverted' m is called the opposite reciprocal. That's your word of the day.

The area of the triangle XYZ is 29.1 square units

Explanation:

Given that the measurements of the sides of the triangle XYZ are $XY = 13$ , $XZ=8$ and $m\angle X=34^{\circ}$

We need to determine the area of the triangle XYZ

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

$Area=\frac{1}{2} yz \ sin X$

Substituting the values, we get,

$Area=\frac{1}{2}(13)(8) \ sin 34$

Simplifying, we get,

$Area=\frac{1}{2}(104) (0.56)$

Multiplying the terms, we get,

$Area=\frac{58.24}{2}$

Dividing the terms, we have,

$Area=29.12$

Rounding off to the nearest tenth, we get,

$\text {Area}=29.1$

Thus, the area of the triangle XYZ is 29.1 square units.

dem82 [27]

9514 1404 393

Answer:

$342.37

Step-by-step explanation:

When a quantity is marked up by x%, its marked-up price is (1 +x/100) times its original price. Tax is effectively a markup.

Louise's costs are ...

$125 + (12.50 +19.50)(1.07) = $159.24

Louise priced her painting at ...

$159.24·(1 +1.15) = $342.37
