Meters are 100 times as large as centimeters. So, if we have 800 centimeters, that is the equivalent of 8 meters.

In this scenario, we want to know how many meters is equivalent to 7 centimeters. Since 1 centimeter is 1/100 of 1 meter, we can multiply the amount of centimeters by 1/100 to get the measurement in meters. 7(1/100) will yield 7/100 or .07 meters.

To write this in scientific notation, we take 7 and multiply it by 1/100 or 10^(-2). This is written "7x10^(-2) m".

7 centimeters in scientific notation is just 7x10^0 because it is a single unit. Scientific notation allows us to compare the size of numbers more easily.

For instance 7.12x10^3 is much larger than 7.12x10^(-3) due to the exponents and how many "10s" we are mulitplying our number by.

Exterior angle theorem <br> what is the value of u? I’m willing to give brainlist!!

KengaRu [80]

Answer: 45

Explanation: two angles that form a Line always equal 180 degrees, so we start with the equation 180-u+47, which is the measure of the missing interior angle measure. All of the angles inside of a triangle also equal 180 degrees, so we can set up this equation to find U:
u-18+u+(180-u+47)=180
We can start to simplify by first simplifying what’s inside the parenthesis:
u-18+u+153-u=180
Then you solve the equation to get
U=45 degrees

if f(x)=2(x)^2+5sqrt(x+2), complete the follwoing statement ( round your answer to the nearest hundreth) : f(0)=_____

Maslowich

Answer:

$f(0)=7.07$

Step-by-step explanation:

We have the function $f(x)=2(x)^2+5\sqrt{(x+2)}$

In this case we want to find the value of f0)

To find f(0) you must replace the x in the function with the number 0 and solve as shown below

$f(0)=2(0)^2+5\sqrt{(0+2)}$

$f(0)=0+5\sqrt{(0+2)}$

$f(0)=5\sqrt{(2)}$

Therefore

$f(0)=7.07$

Two tapes, red and green, with lengths of 415 feet and 780 feet respectively are to be cut into pieces of equal length without r

ICE Princess25 [194]

Answer:

The greatest possible length of the pieces is 5 feet

Step-by-step explanation:

Red = 415 feet

Green = 780 feet

Find the greatest possible length of the pieces.

Find the Highest common factor

415 = 1, 5, 83, 415

780 = 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390 and 780

The Highest common factor of 415 and 780 is 5

The greatest possible length of the pieces is 5 feet

Red = 415/5

= 83 pieces

Green = 780/5

= 156 pieces
