Answer: Hello Luv......

Hope this helps. Mark me brianest please... Anna ♥

Step-by-step explanation:

Answer: -40 < T < 140

From the question, we are informed that the gas that the driver uses freezes at −40° F and evaporates at 140° F.

To get the inequality to represent the temperatures at which the gas in the truck will remain in liquid form, we should note that the temperature will be lower than 140°F but more than -40°F. This can be expressed as:

= -40 < T < 140

Adam and beth each drove from smallville to crown city by different routes. adam drove an an average speed of 40 miles per hour

Anna71 [15]

Adam's average speed = 40 miles per hr

time for the trip = 30 minutes = 0.5 hrs

Distance travelled by adam = speed * time = 40 * 0.5 = 20 miles

Distance travelled by Beth is 5 miles longer means 20 + 5 = 25 miles

Time took by Beth is 20 minutes more means = 30 + 20 = 50 minutes = 0.83 hrs

Average speed of Beth = distance / time = 25 / 0.8333

Average speed of Beth = 30 miles : Answer

Hope it will help :)

Which is the longer trip from Earth, a one-way trip to Mars or a round-trip to Venus?

dimulka [17.4K]

<span>if a trip from earth to mars, is 97/186=.52150

and a trip from earth to venus is 0.2774(now we have to times it by 2 since its a roundtrip),

we get .5548 we can clearly see that .5548>.52150

So roundtrip venus</span>

The base diameter and the height of a cone are both equal to x units.

HACTEHA [7]

By definition, the volume of a cone is given by:

$V = (\frac{1}{3}) * (\pi) * (r ^ 2) * (h)$

Where,

r: cone circular base radius

h: height of the cone

Substituting values we have:

$V = (\frac{1}{3}) * (\pi) * ((\frac{x}{2}) ^ 2) * (x)$

Rewriting the equation we have:

$V = (\frac{1}{3}) * (\pi) * (\frac{x^2}{4}) * (x)$

$V = (\frac{1}{12}) * (\pi) * (x ^ 3)$

Answer:

An expression that represents the volume of the cone, in cubic units is:

$V = (\frac{1}{12}) * (\pi) * (x ^ 3)$

Note: rewrite the options again.

3/4 less or greater <br> than 4/12

erastovalidia [21]

Answer:

4/12 simplified is 1/3

3/4 > 1/3

Or, imagine this:

There are 2 pies, watermelons, pizzas, cookies, whatever fits you. One is cut into 4 pieces and the other into 3. You take the one with 4 pieces and your friend take the one with 3. When you finish, there is only 1 quarter left. However, your friend didn't even finish half. Of course, you ate more.

Weird example but who cares...
