The answer is 157kJ
formula: q=mcT
q= 75 g x 4.18 J/goC x 50 oC
q= 157 kJ
5. Line e and line c
6. Line a and line d
Answer:
29 m³
Step-by-step explanation:
The applicable formula is ...
V = (1/3)Bh
Assuming the height is 10 m, the volume is ...
V = (1/3)(8.7 m²)(10 m) = 29 m³
_____
The shape of the base is irrelevant.
Let smaller number be x/2 and the larger number x.
x/2 + x = 81
x/2 + x = 3x/2
3x/2 = 81
3x = 162
x= 54
The smaller number is 54/2= 27 and the larger number is 54.
Answer:
<em>x - 5y = - 10 </em>
Step-by-step explanation:
y = mx + b (b is y-intercept)
m = 
~~~~~~~~~~~~
x + 4y = 8 ⇔ y = 
x + 2 ⇒ y-intercept is 2 and coordinates of y-intercept are <u><em>(0, 2)</em></u>
(5, 3)
m = 
= 
y = x + 2 (slope-intercept form)
<em>x - 5y = - 10</em> (standard form)
