Nola hiked down a trail at a steady rate for 10 minutes. Her change in elevation was −170 feet. Then she continued to hike down

madreJ [45]

Answer: First portion is greater than second portion.

Step-by-step explanation:

Time taken to hiked down a trail = 10 minutes

Change in elevation = (-) 170 feet

Speed is given by

$Speed=\frac{Distance}{Time}\\\\Speed=\frac{170}{10}\\\\Speed=17\text{ feet per minute}$

Similarly,

Time taken to hiked down a trail = 20 minutes

Change in elevation = (-)220 feet

Speed is given by

$Speed=\frac{Distance}{Time}$

$Speed=\frac{220}{20}\\\\Speed=11\text{ feet per minutes}$

So, we can see that first portion of the hike where he hiked down a trail at a steady rate for 10 minutes and her change in elevation was (-) 170 feet, was her rate of change in elevation greater.

As 17 feet per minutes is greater than 11 feet per minutes.

Help Please I'm taking my finals review

If b=2 and c=3, then
a= √(3²-2²) = √(9-4) = √5

If a=3 and c=6, then
b= √(6²-2²) = √(36-9) = √27 = 3√3

If a=4 and b=6, then
c= √(4²+6²) = √(16+36) = √52 = 2√13

PLEASE SHOW YOUR WORK!!! WILL MARK BRAINLIEST!!!

Answer:

Step-by-step explanation:

3 out of 12 is 1/4, or 0.25, so if you divide 180 by 4, then using the same logic, you can expect 45 kids to have played last year.

3 = 1/4 OR .25 of 12, 12 divided by 4 = 3

180 divided by 4 = 45
