Can some one me with number 28 and 29

28) Calculate the total area of the floor and one tile, then divide the area of the floor by the area of the tile:

The area of the floor is 12^2 = 144 square feet

The area of one tile = 2^2 = 4 square feet

Number of tiles = 144 / 4 = 36 tiles.

29) The seal population is 3.27 x 10^2 which is written in scientific notation.

Since the exponent is a positive two ( 10^2), move the decimal point 2 places to the right:

3.27 x 10^2 = 327

There are 327 seals.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
