Abdull sells computers for a local computer outlet. He gets paid $400 per month plus a commission of 4.2% on all the computer ha
Fed [463]

Ok. So… Let's see if I can solve this one.

So since they wanted 4.2% out of the 640,000 Abdull makes, we can move the decimal(4.2%) to the left twice. Which will get .042 . The afterword-that will allow us to multiply 640,000 dollar with .042 . Which mean Adbull has receive 26,880 cash that year.

Answer for “A” = 26,880

Ok so his annual salary plus his commission. That means his 400 dollar (per month) plus the amount on the sales commission. Which mean… 400 dollar(Monthly) plus 26,880 dollars. Which will get us 27,280

A = 26,880

B = 27,280

(Im not sure about answer B because Im not sure if they are talking about yearly price for both or monthly payment for 400 dollar plus the monthly commission.) But overall, their,you have your answer.

Answer:

B_2=4\pi r^2

see the explanation

Step-by-step explanation:

we know that

The area of the base of a cylinder is given by the formula

B=\pi r^{2}

where

r is the radius of the circular base

If the radius is doubled

then

r=2r

The new base area is

B_2=\pi (2r)^{2}

B_2=4\pi r^2

so

B_2=4B

therefore

The new area of the base is 4 times the area of the original base

9. Raju sells a watch at 5% profit. Had he sold it for 24 more he would have gained 11%. Find the cost price of the watch.​
Ede4ka [16]

Answer:

400$

Step-by-step explanation:

Let C.P. of the watch = Rs. 100

When profit =5%; S.P. = Rs. (100+5)

= Rs. 105

and when profit = 11%;

S.P. = Rs. (100+11)

=Rs.111

Difference of two selling prices

= Rs. 111-Rs.105 = Rs.6

When watch sold for Rs. 6 more; then C.P. of the watch = Rs.

100

6

When watch sold for Rs. 24 more; then C.P. of the watch = Rs.
