What is v6/v5 in simplest radical form?

ira [324]

Answer: $\sqrt{30}/5$

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 $\sqrt{5}$ .

In Anchorage, Alaska, the temperature is 31 degrees at 7:00am. It rises 12 degrees by noon, but then drops 40 degrees overnight.

finlep [7]

7:00 am = 31 degrees
12
------
43 degrees = noon
-40
-------
3 degrees = overnight
So therefore, the final temperature is 3 degrees.

(b) The globe has a radius of 28.5 cm. Find the surface area of the globe. Round your answer to two decimal places. Use:

damaskus [11]

Answer:

$\boxed {\boxed {\sf 10,207.03 \ cm^2}}$

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:

$SA= 4 \pi r^2$

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

r= 28.5 cm

$SA= 4 \pi ( 28.5 \ cm)^2$

Solve the exponent. Multiply the number by itself.

(28.5 cm)²= 28.5 cm * 28.5 cm = 812.25 cm²

$SA= 4 \pi (812.25 \ cm^2)$

Multiply 4, pi and 812.25 centimeters together.

$SA= 12.56637061 (812.25 \ cm^2)$

$SA= 10207.03453 \ cm^2$

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 (10207.03453).

$SA \approx 10207.03 \ cm^2$

The surface area of the globe is approximately 10,207.03 centimeters squared.

I want to know the answer to this question through: (-4, 0), parallel to y =1/2x +3

netineya [11]

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

What does x equal in the diagram?

Effectus [21]

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.
