Answer:

54°

Step-by-step explanation:

$m\angle CDE = \frac{1}{2} \{237 \degree - (360 \degree -237 \degree ) \} \\ \\ = \frac{1}{2} \times \{237 \degree - 123 \degree \} \\ \\ = \frac{1}{2} \times 114 \degree \\ \\ = 54 \degree \\ \\ \huge \red{ \boxed{ \therefore \: m\angle CDE =54 \degree}}$

The Augello family is driving from Columbus to St. Louis at a constant rate of 65 miles per hour. The distance between the two c

Anestetic [448]

Answer:

$y = -65x + 420$

Step-by-step explanation:

Slope-intercept form equation is given as $y = mx + b$

Where,

y = distance remaining

x = hours driven

m = slope/constant rate. In this case, the value of m would be -65. This means the distance will reduce at a constant rate of 65 miles per hour.

b = y-intercept, which is the initial value or the distance between the cities = 420

Plug in the values into the slope-intercept equation, to represent the distance y in miles remaining after driving x hours. You would have:

$y = -65x + 420$

Tim predicts he will get 98 points on the next exam. If Tim actually earned 62 points, what was Tim's percent error? Round your

cupoosta [38]

% change= (new # - original #) ÷ original # x 100

original #= 98
new #= 62

% change= (62-98)/98 x 100
= -36/98 x 100
= -0.36734 x 100
= -36.73%

Rounded to nearest 10th of %= -36.7%

CHECK:
= 98 - (98 * 36.73%)
= 98 - (98 * 0.3673)
= 98 - 36
= 62 new #

ANSWER:
Her percent error was 36.7% (rounded to the nearest tenth of a percent). The negative indicates a decrease.

Hope this helps! :)
