Arrange the following in decreasing order. 3.8 m^2 380 cm? 0.038 km2 3,800 mm Which of the following shows the answers in decrea

Snezhnost [94]

Answer:

C. 0.038 km² > 3.8 m² > 380 cm² > 3800 mm²

Step-by-step explanation:

Convert every measurement to the same unit, say, square metres.

(a) 3.8 m²

No conversion necessary

(b) 380 cm²

$\text{Area} = \text{380 cm}^{2} \times \left (\dfrac{\text{1 m}}{\text{100 cm}} \right )^{2} = \textbf{0.038 m}^{2}$

(c) 0.038 km²

$\text{Area} = \text{0.038 km}^{2} \times \left (\dfrac{\text{1000 m}}{\text{1 km}} \right )^{2} = \textbf{38 000 m}^{2}$

(d) 3800 mm²

$\text{Area} = \text{3800 mm}^{2} \times \left (\dfrac{\text{1 m}}{\text{1000 mm}} \right )^{2} = \textbf{0.0038 m}^{2}$

In decreasing order, 0.038 km² > 3.8 m² > 380 cm² > 3800 mm²

A robin perched in a tree 40 feet above sea level. Directly below the robin, a seagull is flying 13 feet above sea level. Direct

katrin [286]

Answer:

See explanation

Step-by-step explanation:

The question is incomplete. However, I'll solve on a general terms.

Since the robin, seagull and fish are on directly below one another; a possible question could be to calculate the distance between the robin and the clownfish

The given parameters are:

$Robin = +40ft$

$Seagull= +13ft$

$Clownfish= -33ft$

+ represents above sea level while i represents below

The distance is then calculated as:

$Distance = Robin - Clownfish$

$Distance = +40ft - (-33ft)$

$Distance = +40ft +33ft$

$Distance = 73\ ft$

I need to find the answer someone please help

Ludmilka [50]

Answer:

About 1,237 cubic feet.

Step-by-step explanation:

The first step is to know the formula for the volume of a cylinder.

V = pi * r^2*h

You have all the numbers needed because 7ft is the height and the half the diameter (or half of 15) is 7.5. so:

V = pi * 7.5^2 * 7
