Yes
Step-by-step explanation:
40000 x .10 is 4000 in tax. Total after tax would be 36,000
45,000 × .15 is 6750. Total after tax would be 38,250 which is more
X=21
If the triangle are similar then you can divide.
75 divided by 25 is 3
72 divided by 21 is 3
so that means if you take 7 times 3 you will get 21
I'm not sure, but the average time can be 1/250 seconds.
The surface area of a sphere is given by

We deduce

So, in your case, the radius is

The volume of a sphere is given by

So, we have

Answer for no.9:
144.5cm^2
Step-by-step explanation:
base of triangle = 34cm-17cm
=17cm
Area =bh/2
=17cm×17cm/2
=289cm^2/2
=144.5cm^2
