Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{10 \: N}}}}}

Step-by-step explanation:

Given,

Load distance ( LD ) = 2m

Load ( L ) = 800 N

Effort distance ( ED ) = 160 m

Effort ( E ) = ?

<u>Finding the Effort applied</u>

Apply the principal of simple machine :

\boxed{ \sf{L \times LD = E\times ED}}

\longrightarrow{ \sf{800  \times 2 = E \times 160}}

\longrightarrow{ \sf{1600 = 160 \: E}}

\longrightarrow{ \sf{160E = 1600}}

\longrightarrow{ \sf{ \frac{160E}{160}  =  \frac{1600}{160} }}

\longrightarrow{ \sf{E = 10 \: \: newton}}

Effort applied = 10 N

Hope I helped!

Best regards! :D

Explain how the Quotient of Powers Property was used to simplify this expression.
Simora [160]

Answer:

The answer is option 2, by simplifying 9 to 3² to make both powers base 3 and subtracting the exponents.

Step-by-step explanation:

You have to make the expressions into the same base :

\frac{ {3}^{4} }{9}  =  \frac{ {3}^{4} }{ {3}^{2} }

Next, you have to apply Indices Law :

{a}^{m}  \div  {a}^{n} \: ⇒ \: {a}^{m - n}

{3}^{4}  \div  {3}^{2}

=  {3}^{4 - 2}

=  {3}^{2}

Blababa [14]

To Find :

How many gallons of a 80​% antifreeze solution must be mixed with 100 gallons of 20​% antifreeze to get a mixture that is 70​% antifreeze.

Solution :

Let, x gallons of 80​% antifreeze solution is required :

So,

(x \times 80) + ( 100 \times 20 ) = (x + 100 )\times 70\\\\8x + 200 = 7( x + 100)\\\\x = 500

Therefore, 500 gallons of 80% antifreeze solution is required.

A farmer needs to ship 71 pumpkins to a grocery store if each crates can hold 19 pumpkins how many crates Will the farmer need ?
Lesechka [4]

Answer:

The farmer will need 7 crates.

Step-by-step explanation:

<em>It is given that there are 71 pumpkins in total.</em>

<em>And each crate holds 19 pumpkins.</em>

Let the number of crates required be<em> "n".</em>

The total number of pumpkins can be calculated by multiplying number of pumpkins in each crate with total number of crates.

Thus, the equation is

19(n) = 71

n = \frac{71}{19} = 7

Thus, the farmer needs 7 crates to hold total of 71 pumpkins.
