To estimate a square root, find the two perfect squares the number is closest to, then continue with further decimals, i.e. if the question is square root of 5, it is between 4 and 9.  As such, the answer is between 2 and 3.  Alternatively, use a calculator for a quick estimation of many decimal points.

PLEASe help 30POINTS<br><br> What is the length of segment AB ?
lesya692 [45]

Answer:

\sqrt{74}

Step-by-step explanation:

<u>Distance between two points</u>

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

\textsf{let}\:(x_1,y_1)=(2,-6)

\textsf{let}\:(x_2,y_2)=(7,1)

d=\textsf{length of segment AB}

Substituting points into the distance formula and solving for d:

\implies d=\sqrt{(7-2)^2+(1-(-6))^2}

\implies d=\sqrt{5^2+7^2}

\implies d=\sqrt{25+49}

\implies d=\sqrt{74}

Shashi Rimoko earns $620 per week as a chef. He has group
finlep [7]

Out of the weekly amount that Shashi Rimoko makes, a deduction of $37.93 is made for insurance.

The total Medical cost is $9,560 and out of this, the amount paid by Shashi per year is:

<em>= Amount x (1 - percentage paid by restaurant)</em>

= 9,560 x ( 1 - 80%)

= $1,912

The amount he pays for Dental coverage is:

<em>= Amount x (1 - percentage paid by restaurant)</em>

= 172 x (1 - 65%)

= $60.20

The total amount he pays for insurance per year is:

<em>= Medical + Dental </em>

= 1,912 + 60.20

= $1,972.20

The weekly deduction is:

<em>= Year amount / No. of weeks in year </em>

= 1,972.20 / 52

= $37.93

In conclusion, $37.93 is deducted from his paycheck every week.

William has a 26 -liter glass tank. First, he wants to put some marbles in it, all of the same volume. Then, he wants to fill th
Ann [662]

Answer: 0.06 litre or 60 ml


Step-by-step explanation:

Given: The capacity of glass tank= 26 liter

If he add 20.9 liters of water after 85 marbles to fill it completely, then

The volume of 85 marbles= 26-20.9=5.1\ liters

Since, the marbles have same volume.

∴ Volume of each marble= \frac{\text{volume of 85 marbles}}{\text{85}}

⇒ Volume of each marble=\frac{5.1\ litre}{85}=0.06\ liters

In milliliters, Volume of each marble=0.06\times1000=60ml
