Hello,
The line passes through (-1,3) and (9,11)
slope=(11-3)/(9+1)=8/10=4/5
y-3=4/5(x+1)
==>y=4/5 *x +19/5
Answer: 62
Explanation: It's an equilateral triangle
Answer:
B. 30°
Step-by-step explanation:
By remote interior angle theorem:
100° = x + 70°
100° - 70° = x
30° = x
x = 30°
Quadratic trapezoids have only one pair of parallel sides
Time taken to cook 500 g or half kg of meat =30 minutes
time taken to cook 1 kg of meat = 30/0.5 = 60 minutes
time taken to cook 2.5 kg of meat = 2.5* 60 = 150 minutes
Now extra 20 minutes are also required for cooking.
So total time taken to cook 2.5 kg of meat = 150 minutes + 20 minutes
=170 minutes
Answer is time taken to cook a joint of meat weighing 2.5 kg is 170 minutes.
