in triangle ABD,

angle BAD+angleABD+angleADB=180 DEGREE (sum of the sngle of triangle)

angle BAD+75+30=180

angle BAD=180-165      therefore,angle BAD=15

Answers

Answer:

y = 2/3x - 1/2

Step-by-step explanation:

y = 2/3x - 1/2 is a linear function. It contains a slope and a y-intercept and every x value will produce a unique y value.

y = 4/x + 1 is a rational function, as it contains a fraction.

The actual amount of chocolate chips on the tray were 265

Required

The percent error

Step two:

The formula is

percent error= actual-expected/expected*100

percent error= 265-250/250*100

percent error=15/250*100

percent error=0.06*100

Step-by-step explanation:

a) The slope (m) is given: -3.

__

b) The y-intercept (b) can be found from the slope (m) and the given point (h, k) using the relation ...

  b = k -mh

  b = 4 -(-3)(-3) = 4 -9

  b = -5 . . . y-intercept

__

c) Of course, the slope-intercept equation is ...

  y = mx +b

  y = -3x -5

Using the figure above, what are the measures of the 3 angles in triangle DEF? PLS HURRY! THANKS

Answers

Answer:

F= 34 degrees (alternate angles are equal)

To find D

we first have to find the angles at AB

B =180- 165 (sum of angles on a straight line = 180°)

therefore B = 15°(we'll use this to find the angle at E)

A=34 (from the diagram)

so,

D = 180- (15 + 34) [sum of angles in a triangle = 180°]

D = 131°

E=15° (alternate angles are equal )

How would you write 0.5 Repeating as a fraction

Answers

Let x = 0.555…

Then 10x = 5.555…

Subtract one from the other to get

10x - x = 5.555… - 0.555…

Notice how the fractional parts on the right cancel. This leaves you with

9x = 5

and so

x = 5/9

Answer:

59

Step-by-step explanation:

Since this fraction repeats the same number it must have a denominator of 9 and a numerator of the repeating digit the repeating digit is 5 so the fraction is 59
