No. A yard is 3 feet, so 29 yards is 87 feet which means they are equal.


How many feet can you travel after 12 seconds at 87 miles per hour?

Since there are 3600 seconds in one hour, then we have: x/87 = 1/3600 cross multiply 3600x = 87 divide by 3600 to both sides x = 0.024 Thus, in one second you can travel 0.024 miles, and in 12 seconds you have traveled 0.29 miles (12 x 0.024).

What is 3 to the power of 2 times 87 to the power of 99?

Well 3 to the power of 2 is 6 and 6 times 87 to the power of 99 so when you think about it how many times does six go into 87 so that is when you figure out The answer.


On a sunny day if a 36inch yardstick casts a 21inch shadow how tall is a building whose shadow is 168ft?

So, I can't give you the answer with the appropriate formulas or w/e but this is how I figure it out in my headFind the ratio between the yard stick and it's shadow36/21 = 1.71This means that object creating the shadow is 171% taller that its shadow is longFind the amount of inches in 168 feet (this is to be more accurate with your answer)168 * 12 = 2016 inchesMultiply the previous number by the ratio found before2016 * 1.71 = 3447.4 inches (or 287.3 feet)If a 36 inch yardstick casts a 21 inch shadow, a building whose shadow is 168 feet is 287.3 feet talls'howyagottadoitboyyiieAnother answer:Using trigonometry will give you a more accurate answerTangent ratio = opposite (the yardstick) divided by the adjacent (yardstick's shadow)Tangent ratio = 36/21 = 12/7 in its lowest termsNow rearrange the formula to find the height of the buildingTangent ratio*adjacent (the building's shadow) = opposite (the building)12/7*168 = 288The height of the building is 288 feet.
