Answer:
99 yards
Step-by-step explanation:
To find the perimeter of a rectangle, the equation is perimeter = 2(width) +2(height). When we plug the known variables into this equation, it is 364 = 166 + 2(height). Now all we have to do is isolate the variable like in any algebra equation, leaving us with our final answer of 99 = height.
28. Answer: 86% decrease
<u>Step-by-step explanation:</u>
Original Sphere has a radius of 100% → r =1
Surface Area of Original Sphere:
S.A. = 4πr²
= 4π(1)²
= 4π
New Sphere has a diameter of 75% → d = 0.75 → r = 0.375
Surface Area of New Sphere:
S.A. = 4πr²
= 4π(0.375)²
= 0.5625π
<em>The negative sign represents a decrease.</em>
