Scott works mowing lawns and babysitting. He earns $8.80 an hour for mowing and $8.10 an hour for babysitting. How much will he earn for 3 hours of mowing and 1 hour of babysitting?

Scott earns $34.50

Step-by-step explanation:

You can use the equation 8.80x + 8.10y to represent how much he will make. Then, plug in 3 to x and 1 to y. 8.80 x 3 = 26.40. 8.10 x 1 = 8.10. Add your products 26.40 and 8.10 together to get $34.50. So, he earned $34.50.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
