Answer:
2400kJ
Step-by-step explanation:
Step one:
given data
power P= 400W
time = 10minutes
to seconds= 60*10 = 600 seconds
Required
the energy
Step two:
we know that Energy= power * time
E=P*t
E=400*600
E=240000
E=2400kJ
She converts 2400kJ into other forms
Answer:
65
Step-by-step explanation:
if they are similar their sides are in proportion and so are the corresponding medians
to see their corresponding sides line up the names of the triangles
N Q Z
⇵⇵⇵
C B K
BK / QZ = 45/27 ; substitute whit what you see in the picture
(4x+1) / (2x+7) = 45/27 ; cross multiply
27( 4x+1) = 45( 2x+7) ; distribute
108x + 27 = 90 x + 315; subtract 90x and 27 from both sides
108x -90x = 315 -27; combine like terms
18x = 288; divide both sides by 18
x=16
BK = 4* 16 +1 = 65
