On square PQRS below, if Q is located at (7,0) and R is located at (5,-8) what is the length of SR
jenyasd209 [6]

the length of SR is 2\sqrt{17} .

<u>Step-by-step explanation:</u>

Here we have , On square PQRS below, if Q is located at (7,0) and R is located at (5,-8) . We need to find Length of side SR . Let's find out:

We know  that  , In a square there are  4 sides , and length of every side is same . So side length of SR = side length of QR . Now , Let's find side length of QR .

We know that distance between two points Q(x_1,y_1),R(x_2,y_2) given by :

⇒ QR = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Two points given are Q(7,0), R(5,-8) :

⇒ QR = \sqrt{5-7)^2+(-8-0)^2}

⇒ QR = \sqrt{(2)^2+(-8)^2}

⇒ QR = \sqrt{4+64}

⇒ QR = \sqrt{68}

⇒ QR = 2\sqrt{17}

But QR=SR , Therefore , the length of SR is 2\sqrt{17} .

a bricklayer needs to order 6300kg of building sand.one grain of this sand weighs 7x10^-5. how many grains of sand are there in
gavmur [86]

Answer:

44.1 x 10^-2

Step-by-step explanation:

Since one grain

= 7 x 10^-5

6300kg = 7 x 10^-5 x 6300

Put 6300 in standard form

7 x 10^-5 x 6.3 x 10^3

Multiply the whole numbers and add the exponents

7 x 6.3 x 10^-5 + 3

44.1 x 10^-2

There are 44.1 x 10^-2 grains of sand in 6300kg
