Since you are blowing warm air, the air molecules are moving fast so it makes the water expand. By the way that's what happens to a thermometer and I think this is a science question :)

The total money earned if Lee sold four scarves at twenty dollars each.

leonid [27]

Answer:

$80

Step-by-step explanation:

If we have four scarves, and each costs $20, we can multiply these two numbers to find the total profit made.

$20\cdot4$

2 times 4 is 8, and adding a 0 to that is 80.

Hope this helped!

In the figure, angle B measures 44°, angle A measures 62°, and angle E measures 50°.

Gre4nikov [31]

We don't need the figure
angle b = 44 degrees
angle a = 62 degrees
angle e = 50 degrees
angle f = unknown
we know that
angle a + b + e + f = 180 degrees
50 + 44 + 62 + f =180 degrees
f= 180-50-44-62
but here there is only one blank so we have to add 44 and 62 to make one number that is 106
therefore, f = 180-50-106
if you further want to solve it angle f is 24
