Find the perimeter of the scale artwork
P=2(l+w)
P=2(2.5+1.75)
=2(4.25)= 8.5 in

1 in = 0.5 ft
8.5in = 0.5(8.5)
=4.25ft = 51 in
the actual perimeter is 51 in or 4.25 ft

A triangle has angles measuring 10 degrees, 40 degrees and 130 degrees with side lengths of 23 cm, 84 cm and 100 cm. Classify th
AnnyKZ [126]

Answer:

<u>The correct answer is D. obtuse scalene</u>

Step-by-step explanation:

1. Let's recall that a equilateral triangle has its three sides of the same length. An equilateral triangle is always equiangular. This is not our given triangle.

2. Let's recall that an isosceles triangle has two sides of the same length. This is not our given triangle.

<u>3. Finally, let's recall that in a scalene triangle, none of the sides are the same length. And if one of the given angles is greater than a right angle, measures more than 90 degrees, it is an obtuse triangle. This is our given triangle.</u>

<u>The correct answer is D. obtuse scalene.</u>

PLEASE HELP QUICKLY!!!! What is the equation of the line with a slope of -3/4 that goes through the point (−6, 3)?
Yakvenalex [24]

Answer:

y=-\frac{3}{4}x-\frac{3}{2}

or

y=-0.75x-1.5

Step-by-step explanation:

step 1

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=-\frac{3}{4} \\point\ (-6,3)

substitute

y-3=-\frac{3}{4}(x+6)

step 2

Convert to slope intercept form

y=mx+b

we have

y-3=-\frac{3}{4}(x+6)

Isolate the variable y

y-3=-\frac{3}{4}x-\frac{9}{2}

y=-\frac{3}{4}x-\frac{9}{2}+3

y=-\frac{3}{4}x-\frac{3}{2}

the radius of a circle is 10 using pi which equation expresses the ratio of the circumference of the circle to the circle's diam
grigory [225]

Answer:

pi

Step-by-step explanation:

The radius of the circle is 10 units

The circumference of a circle is given by the formula:

  C = 2 * pi * r

The diameter of a circle is twice the radius

d= 2r

We want the ratio of the circumference to the diameter

C/d  = (2*pi*r)/ 2r  

Canceling out the 2 and the r, we are left with pi

C/d = pi
