Answer:
165
Step-by-step explanation:
First we need to find the area of the field, A = r^2 * pi
The radius is 290 / 2 = 145 feet
A = 145 * 145 * 3.14 = <u>66018.5</u> sqr feet
One bag covers 400 sqr feet
Divide the Area by 400 sqr feet to find number of bags needed.
66018.5 / 400 = <u>165</u>
He will need at least 165 bags to cover the field
Answer:
1 1/2
Step-by-step explanation:
its 100% correct.
It will be right angle triangle. The two vectors beginning at the same vertex
of a triangle are <2,3> and <-3,2> is classified as right-angled
triangle. It is classified as a right-angled triangle because the dot product
of the vectors are 0.
this formula, doesn't rely on a product, relies on a "sum", or is namely an arithmetic sequence, aₙ₋₁ -3 is another way of saying, the value of the previous term minus 3, so it relies on the ordinal value of a term, so is an recursive formula, well, let's get it when n = 4.
