Answer:

1) a body of air with horizontally uniform temperature, humidity, and pressure.

2) the foremost part or surface of anything. the part or side of anything that faces forward: the front of a jacket.

3) A cold front is often associated with showers and thunderstorms. As it advances, often quite rapidly (50 to 65 km [30 to 40 miles] per hour), the cold air, which is relatively dense, undercuts the displaced warm air, forcing it to rise.

4) Cold Fronts. When a cold front passes through, the weather becomes significantly colder and drier. (It isn't uncommon for air temperatures to drop 10 degrees Fahrenheit or more within an hour of a cold frontal passage.) The weather map symbol for a cold front is a blue curved line with blue triangles.

5) When a cold front passes through, temperatures can drop more than 15 degrees within the first hour. Symbolically, a cold front is represented by a solid line with triangles along the front pointing towards the warmer air and in the direction of movement.

Since p is very much less than q, meaning that even if q is added to p, r would still be negative. So b is incorrect. C isn't an equation, so the answer is A.

B 2,863 m/h

D 58.4 m/h south

Answers

Answer: It is C

Step-by-step explanation:

To solve for distance use the formula for distance d = st, or distance equals speed times time.

distance = speed x time

Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.

distance = rate x time

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

speed = distance/time

To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

time = distance/speed

Answer: Ethan sold more than kayla by [tex]\frac{1}{12} gallons[/tex]

Since we have given that

Quantity of lemonade sold by Ethan is given by

[tex]\frac{2}{3}[/tex] gallons

Quantity of lemonade sold by Ethan and Kayla together is given by

1 1/4 gallon = 5/4

Quantity of lemonade sold by Kayla only is given by

[tex]\frac{5}{4}[/tex] - [tex]\frac{2}{3}[/tex]

= [tex]\frac{5-8}{12}[/tex]

= [tex]\frac{7}{12}[/tex]

To get who sold more lemonade we will first make the denominator same,

Denominator of 3 and 12 = 12

So,

[tex]\frac{2 x 4}{ 3 x 4} = \frac{8}{12}[/tex]

Compare Ethan and Kayla ,

We know that

[tex]\frac{8}{12} \geq \frac{7}{12}[/tex]

So, Ethan sold more lemonade than Kayla .

[tex]\frac{8}{12}[/tex] - [tex]\frac{7}{12}[/tex] = [tex]\frac{1}{12}[/tex]
