A square bathroom has an area of 100m2. What is the distance from

inysia [295]

Answer:

$10\sqrt{2}$ meters

Step-by-step explanation:

The bathroom is in the shape of a square. The area of square is given as:

$A=s^2$

Where

s is the length of the side

We know area is 100, thus:

$A=s^2\\100=s^2\\s=\sqrt{100} \\s=10$

The side length of the square is 10 meters.

The distance from one corner to another corner is known as the "diagonal".

We use the formula below to get the distance of the diagonal:

$d=\sqrt{2}s$

Where

d is the length of diagonal

s is the length of side [here, 10]

THus, length of diagonal is:

$d=\sqrt{2}(10)\\ d=10\sqrt{2}$ meters

Express the following in scientific notation: 0.0000079

Law Incorporation [45]

Answer:

7.9 * 10 ^-6

Move the decimal 6 places to the left so there is one number before the decimal

0.0000079

7.9

The exponent is -6 ( negative because we moved it to the left)

7.9 * 10 ^-6

Can you help with this please.

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - two points P ( 5 , 10 ) and R ( 12 , 14 ) on the cartesian plane

To find - distance between the two points

Using the distance formula ~

$\qquad\underline{d(PR) = \sqrt{( x_{2} - x_{1}) {}^{2} + ( y_{2} - y_{1}) {}^{2} }} \\ \\$

we have ,

$\longrightarrow x_{1} = 5 \\ \longrightarrow x_{2} = 12 \\ \\ \longrightarrow \: y_{1} = 10 \\ \longrightarrow \: y_{2} = 14$

substituting the values in the formula , we get

$d(PR) = \sqrt{(12-5) {}^{2} + (14-10) {}^{2} } \\ \\ \implies \: d(PR) = \sqrt{(7) {}^{2} + ( 4) {}^{2} } \\ \\ \implies \: d(PR) = \sqrt{49 + 16} \\ \\ \implies \: d(PR) = \sqrt{65} \\ \\ \implies \: d(PR) = 8.1 \: units \: (approx)$

hope helpful :)

Answer:

i think probably x = 10

Step-by-step explanation:

sin(60°) = 5√3/x

√3/2 = 5 √3/x

√3 x = 10√3

x = 10
