algol13

Answer:

66

Step-by-step explanation:

105+420=525   (Total Money)

7x3.25=22.75   (Cost of all bracelets)

8x11.74=93.92   (Cost of all necklaces)

93.92+22.75=116.67   (Cost of all Christmas presents)

525-116.67=408.33   (Total money - Cost of all Christmas presents)

408.33/6.15=66.39...   (Amount of necklaces)

since in real life you can only buy a whole number of things, you would round down 66.39 to 66. I hope this helped!

Write the equation of the circle centered at (-4,3) with a radius of 7
Harrizon [31]

Answer:

(x + 4)² + (y - 3)² = 49

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 4, 3) and r = 7 , thus

(x - (- 4))² + (y - 3)² = 7² , that is

(x + 4)² + (y - 3)² = 49

On a piece of paper, use a protractor to construct a triangle with angle measures of 100° and 30°.
yanalaym [24]

The third angle measures 50° and all sides have different lengths.

<h3>What is a triangle?</h3>

A triangle is a polygon with three sides and three angles. Types of triangles are<em> isosceles, equilateral, scalene and right angled.</em>

The sum of angles in a triangle is 180 degrees.

A triangle with angle measures of 100° and 30°, let x represent the third angle, hence:

x + 100 + 30 = 180° (sum of angles in a triangle)

x = 50°

Also, all sides have different lengths since all the angles are different.
