Answer: 
Step-by-step explanation:
You should get this answer because the simpliest form of a radical is that you shouldn't have any radical in the denominator. In order to get rid of the radical sign in the denominator, you have to multiply the numerator and the denominator with the

3 degrees = overnight
So therefore, the final temperature is 3 degrees.
Answer:

Step-by-step explanation:
Surface area is the total area of the surface of an object. A globe is a sphere and the formula for calculating a sphere's surface area is:

The radius (r) of the globe is 28.5 centimeters. Substitute this value into the formula.

Solve the exponent. Multiply the number by itself.
- (28.5 cm)²= 28.5 cm * 28.5 cm = 812.25 cm²

Multiply 4, pi and 812.25 centimeters together.


Round to two decimal place or the hundredth place. The 4 in the thousandth place to the right (10207.03453) tells us to leave the 3 in the hundredth place (10207.0<u>3</u>453).

The surface area of the globe is approximately <u>10,207.03 centimeters squared.</u>
parallel lines have negative reciprocal slopes
so 1/2 becomes -2
point slope form
y-y1 =m(x-x1)
y-0 = -2(x--4)
y =-2(x+4)
y=-2x-8
Answer:
x = 147 degrees
Step-by-step explanation:
The sum of angle x and 33 degrees must be 180 degrees. Thus, to find x, subtract 33 degrees from 180 degrees, obtaining 147 degrees.
