Multiply: (-5qr) × (-2pqr) × pq​
ahrayia [7]

Answer:

The product of (-5·q·r) × (-2·p·q·r) × p·q is 10·q³·r²·p²

Step-by-step explanation:

The question relates to the rules of multiplication of variables and indices rules, and simplifification of an expression ;

The given expression is (-5·q·r) × (-2·p·q·r) × p·q

Therefore, we have;

(-5·q·r) × (-2·p·q·r) × p·q = (-5) × (-2) × q×q×q × r×r ×p×p = 10 × q³ × r² × p²

10 × q³ × r² × p² = 10·q³·r²·p²

∴ (-5·q·r) × (-2·p·q·r) × p·q = 10 × q³ × r² × p² = 10·q³·r²·p²

(-5·q·r) × (-2·p·q·r) × p·q = 10·q³·r²·p².

Of 1800 students enrolled in school 55% are girls. of the girls attending this school 30% take the bus to school
leonid [27]
55% of 1800 = 0.55(1800) = 990...so there are 990 girls in the school

30% of 990 = 0.30(990) = 297...so there are 297 girls who take the bus

snow_lady [41]

Answer:

We can see from the given numbers in the data that there is an outlier. This means that mean or average is not a good measure of center. Also, there is no repeating number to give us the mode of the given. The answer is therefore, median is the only appropriate measure of center.

Show that the equation represent a sphere, and find its center and radius. 3x2+3y2+3z2=10+6y+12z
mihalych1998 [28]

Answer:

Center of sphere = (0, 1, 2)

Radius of sphere = \dfrac{5}{\sqrt3}\text{ units}

Step-by-step explanation:

We are given the following in the question:

Equation of sphere:

3x^2+3y^2+3z^2=10+6y+12z

Formula:

The equation of sphere is of the form

(x-a)^2 + (y-b)^2 + (z-c)^2 = r^2\\\text{where (a,b,c) is the centre of sphere and r is the radius of sphere.}

Simplifying the given equation we get,

3x^2+3y^2+3z^2=10+6y+12z\\\text{Dividing by 3}\\x^2 + y^2 + z^2 = \dfrac{10}{3} + 2y + 4z\\\\x^2 + y^2 -2y + z^2-4z = \dfrac{10}{3}\\\\\text{Adding 1 and 4 on both sides, we get,}\\\\x^2 + y^2 -2y +1 + z^2-4z + 4 = \dfrac{10}{3} + 1+ 4\\\\(x-0)^2 + (y-1)^2 + (z-2)^2 = \dfrac{25}{3}\\\\\text{Comparing with the equation of sphere}\\a = 0\\b = 1\\c = 2\\\\r^2 = \dfrac{25}{3}\\\\r = \sqrt{\dfrac{25}{3}}= \dfrac{5}{\sqrt3}

Center of sphere = (0, 1, 2)

Radius of sphere = \dfrac{5}{\sqrt3}\text{ units}
