8/9 is the larger. 8/9 - 7/8 = 64 /72 - 63/72 = 1/72.

[ $\frac{7}{8}=\frac{7\cdot9}{8\cdot9}=\frac{63}{72}\\\\\frac{8}{9}=\frac{8\cdot8}{9\cdot8}=\frac{64}{72}\\\\\frac{63}{72} < \frac{64}{72}\to\frac{7}{8} < \frac{8}{9}$

The answer:

according to the image, the main theorem concerning right triangle similarity is as follow:
the altitude to the hypotenuse of a right triangle divides the triangle into two triangles that are similar to the original triangle and each other,

in our case, KL is the altitude, and by applying theorem, we get three triangles that are similar:
therefore:
△JKL ~ △JKM
△JKM ~ △JKM
△JMK ~ △KML

If an electric kettle uses

cupoosta [38]

Answer:

The energy used in 3.5 hours = 5.25 kilowatts

Step-by-step explanation:

Energy used by electric kettle:

$2\frac{1}{4}=\frac{9}{4}=2.25$ kilowatts

Time taken by electric kettle:

1.5 hours

Electric kettle's rate in kilowatts per hour can be calculated by dividing the spent energy i.e. 2.25 kilowatts by the time taken i.e. 1.5 hours.

Therefore,

Electric kettle's rate = 2.25 kilowatts / 1.5 hour

= 1.5 kilowatts per hour

Thus, the energy used in 3.5 hours = 1.5 × 3.5

= 5.25 kilowatts

Therefore, the energy used in 3.5 hours = 5.25 kilowatts
