Answer:
r=9/2 or 4.5
Step-by-step explanation:
First of all our goal is to get R by itself
by cross multiplying we get,
(r+3)*3=5r
by distributive property we get
3r+9=5r
substracting 3r from both sides we get
9=2r
by dividing by 2 in both sides we get
r=9/2 or 4.5
10.79/1200=.009
.009*1200=10.79 this is a double check to make sure our price per square foot is correct.
.009*4000=$36.00
It will cost $36.00 to seed the 4,000 square feet at that price.
10√2 is the answer for square root of 200
Answer:

Step-by-step explanation:
<h3><u>Statement:</u></h3>
- If a quadrilateral is inscribed in a circle, the opposite angles add up to 180 degrees.
<h3><u>According to the statement:</u></h3>
∠D + 88° = 180°
<em>Subtract </em>88 to both sides
∠D = 180° - 88°
∠D = 92°
