Ella needs to cut down 10.5 trees for every five cabins she builds. how many trees will ella need to cut down to build 10 cabins and 15 cabins

She will need to cut down 21 trees for 10 cabins and 31.5 trees for 15 cabins. Hope this helps, and be sure to mark Brainliest if this answer is correct!

If Ella needs to cut down 10.5 trees for every 5 cabins

Then for 10 and 15 we can multiply 10.5

10 divided by 2 is 5, so to find how many trees we need for 10 cabins, we can multiply the trees you need by 2

So 10.5 x 2 = 21

To build 10 cabins, Ella will need 21 trees

15 divided by 5 = 3 so to find how many tress we need for 15 cabins, we can multiply the trees needed by 3

So 10.5 x 3 = 31.5

To build 15 cabins, Ella will need to cut down 31.5 trees

I hope this helps! Please mark my answer as the brainliest if it was the best <3

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
