easy

180 is a triangle

so

exterior+interior=180

so 180-123

57

now add all up to 180

180=57+x+69

x=54

I. The Bread Machine (25 points)
Naddika [18.5K]

It would take 125 loaves at a cost of $200 for the breadmaker and store bought bread to cost the same.

<h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept.

Let x represent the rate of cost of one loaf and y represent the total cost, hence:

y = 0.8x + 100

The rate of cost of one loaf is $0.8 and the start up cost is $100.

For the second bread it is given by:

y = 1.6x

The graph of the two equations cross at (125, 200)

It would take 125 loaves at a cost of $200 for the breadmaker and store bought bread to cost the same.

Ulet rolls 2 fair dice and adds the results from each. Work out the probability of getting a total of 7.
kiruha [24]

Answer:

7/ 36

Step-by-step explanation:

Roll of 2 fair six sided die :

Sample space = 6² = 36

Sum of 7:

(1,6) ; (6,1) ; (3,4) ; (4,3) ; (2,5) ; (5,2) = 6

Probability = required outcome / Total possible outcomes

Required outcome = 7

Total possible outcomes = 36

P(obtaining a sum of 7) = 7 / 36
