Awall in marcus’ bedroom is 8 1/3 feet high and 16 1/5 feet long. if he paints 1/3 of the wall blue, how many square feet will be blue?

45 ft^2

Step-by-step explanation:

First find the total area of this one wall.  It is (8  1/3 ft)(16  1/5 ft), or approx. (8.33 ft)(16.2 ft) = 134.95 ft^2.

One third of that total area comes to 44.98 ft^2, or approx 45 ft^2.

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

it should be a and d. lmk if i'm wrong xd
