The answer would be 180 degrees.

Any triangle, whether it's right, obtuse, acute, etc., will always equal 180 degrees. As it is stated, if ABC is a triangle, then ∠ABC + ∠BCA + ∠CAB = 180 degrees.

Write an equation for the line of fit for this data in the form y=mx+b where x is latitude and y is temperature.

Answer:

$y = -x + 115$

Step-by-step explanation:

Given

See attachment for graph

Required

The equation of best fit

First, we pick two corresponding points on the graph,

We have:

$(x_1,y_1) =(55,60)$

$(x_2,y_2) =(45,70)$

Calculate slope (m)

$m = \frac{y_2 -y_1}{x_2 - x_1}$

This gives:

$m = \frac{70 - 60}{45 - 55}$

$m = \frac{10}{-10}$

$m = -1$

The equation is the calculated using:

$y = m(x - x_1) + y_1$

This gives

$y = -1(x - 55) + 60$

Open bracket

$y = -x + 55 + 60$

$y = -x + 115$

Quinn rode her bike 5/6 of a mile. Beth rode her bike 1/3 of a mile. How much farther did Quinn ride that Beth?

garik1379 [7]

First multiply 1/3 by 2. 1 times 2 is 2 and 3 times 2 is six. Therefore 1/3 equals 2/6. Now subtract 5/6 by 2/6, which equals 3/6, now simplify it which makes it 1/2.

Answer: Quinn rode 1/2 a mile more than Beth.
