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

A hemisphere has a diameter of 26 centimeters. What is the volume of a sphere with the same radius?
salantis [7]
r= \frac{d}{2}= \frac{26}{2} \;\Rightarrow r=13\,cm  \\  \\ &#10;V= \frac{4}{3} \pi r^3 \\  \\ &#10;V= \frac{4}{3} \pi \,(13)^3 \\  \\ &#10;V= \dfrac{4\cdot 2197}{3} \pi \\  \\ &#10;V= \frac{8788}{3} \pi\approx 9202,77\,cm^3

The equation F=9/5C+32 relates temperature measured in degrees Celsius, C, to degrees Fahrenheit, F. Determine wether there is a
Rama09 [41]

Answer: yes they have a proportional relationship

Step-by-step explanation:

Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

Step one : let us test say c=1

F=9/5*1+32

F=9/5+32

F=1.8+32

F=33.8

Say c=2

F=9/5*2+32

F=9/10+32

F=0.9+32

F=32.9

Observe that as c increases

F reduces Hence they have a proportional relationship
