Answer:

$2.2794$ × $10^8$

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point.

$2.2794$

The number of decimal places you move will be the exponent on the

10 .

$10^8$

If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:

Part 1) $A=12.25\ m^2$

Part 2) $P=14\ m$

Step-by-step explanation:

The question in English is

A carpenter will cut plywood measuring 3.5 meters x 3.5 meters. Determine the area and perimeter of the plywood.

Part 1) Determine the area

we know that

The area of a square is given by the formula

$A=b^2$

where

b is the length side

we have

$b=3.5\ m$

substitute

$A=3.5^2=12.25\ m^2$

Part 2) Determine the perimeter

we know that

The perimeter of a square is given by the formula

$P=4b$

where

b is the length side

we have

$b=3.5\ m$

substitute

$P=4(3.5)=14\ m$

3²+3[2³(√49 - 2²)(3² - 2³)-2²}

lukranit [14]

$3^2+3[2^3( \sqrt{49}-2^2)(3^2-2^3)-2^2]$

Right off the bat, this may look crazy, but if we take it step by step, it will be much easier. So, let's take it step by step. If any step doesn't make sense to you, you can always hmu.

$9+3[8( 7-4)(9-8)-4]$
$9+3[8( 3)(1)-4] = 9+3[24-4] = 9+3[20]$
$9+60 = 69$

Your answer is 69.

Given:

A zip line goes from 28 feet to 11 feet in the air. The angle of depression is 85°.

To find:

The length of the zip line where there is no rider.

Solution:

A right-angled triangle can be formed using the given data.

The difference in height between the start and end of the zipline is $28-11=17$ . The angle of the triangle is 85°.
