One floor of a dollhouse is 1.6 feet tall. The dollhouse contains two levels of living areas and an attic for a total of 2.5 floors. Jaime estimates the height of the dollhouse by computing 2 times 3. How does her estimate compare to the actual height of the dollhouse? Her estimate is greater than the actual height because both factors were rounded up.

Her estimate is less than the actual height because both factors were rounded up.

Her estimate is greater than the actual height because both factors were rounded down.

Her estimate is less than the actual height because both factors were rounded down.

Her estimate is greater than the actual height because both factors were rounded up.

Step-by-step explanation:

Given that:

Height per floor of doll house = 1.6m

Total number of floors in doll house = 2.5

Estimated height of doll house = 2 *3 = 6 meters

Actual height of doll house :

1.6m * 2.5 = 4 meters

Her estimate is greater than the actual height because both factors were rounded up.

Height per floor of 1.6m was rounded to 2m

Number of floors, 2.5 was rounded to 3

Hence, the cause of overestimation

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

step-by-step explanation: yes
