Answer:

Rosa is closer to the correct depth.  

Step-by-step explanation:

To show that two measurements are nearly equivalent, we must convert one of the measurements to the other unit.

1 m = 3.281 ft

\text{Depth } = \text{1644 ft} \times \dfrac{\text{1 m}}{\text{3.281 ft}} = \textbf{501.1 m}

Neither is correct but Rosa is closer to the correct depth.

{35 POINTS)What are the solutions of 2a^3-3a^2=8a-12 ?
valentinak56 [21]
Greetings!

2a^3-3a^2=8a-12
Add -(8a-12) to both sides.
(2a^3-3a^2)+-(8a-12)=8a-12-(8a-12)
Simplify.
2a^3-3a^2-8a+12=0
Rearrange.
2a^3-8a-3a^2+12=0
Factor Out 2a.
2a(a^2-4)-3a^2+12=0
Factor Out the difference of squares.
2a(a-2)(a+2)-3a^2+12=0
Factor out -3.
2a(a-2)(a+2)-3(a^2-4)=0
Factor Out the difference of squares.
2a(a-2)(a+2)-3(a-2)(a+2)=0
Find Common Factor.
(a+2)(a-2)(2a-3)=0
Set Factors to Equal 0.
(a+2)=0 \\  \\ (a-2)=0 \\  \\ (2a-3)=0
a=-2 \\ \\ a=2 \\ \\ a=3/2

Hope this helps.

What is the relationship between the number of sides of the base of a prism and the number of lateral faces? The number of sides
slamgirl [31]

Answer:

Every prism has as many faces, and edges, as its base has sides. Thus, a prism with an octagonal (eight sided) base has eight lateral faces, and eight lateral edges. Each lateral face meets two other lateral faces, as well as the two bases. As a consequence, each lateral face is a four sided polygon.

If $500 is shared in the ratio 2:3:9 then the difference between the largest and the smallest shares is
madreJ [45]

Answer:

$250

Step-by-step explanation:

Total parts:

2+3+9 = 14

500/14 = 250/7

2×250/7 : 3×250/7 : 9×250/7

500/7 : 750/7 : 2250/7

The largest share is 2250/7, the smallest share is 500/7.

Find the difference.

2250/7 - 500/7 = 250

The result of our calculations about the rate and time are:

  • r=d/t
  • 200000m/hr
  • 200km/hr
  • km/hr

<h3>What is rate?</h3>

Rate can be regarded as the given object with respect to time.

falcon flies= 800,000 meters

t= 4 hours

We were given the  formula as (d = rt)

d= distance

r = rate

t = time

We can make our calculations as:

part a:

r=d/t

part b:

falcon's rate in meters per hour = 800,000 meters / 4 hours = 200000m/hr

part c:

falcon's rate in kilometers per hour=(200000m/hr *(1/1000)=200km/hr

part d:

km/hr
