Explain why can be helpful to use partial quotients is when dividing

Mathematics
1 answer:
Anastasy [175]4 years ago

This is because the sum of all the partial quotients will lead you to the final quotient. This is a technique in division where you make small estimates to reduce the dividend. Then, when it is reduced completely, you will just add the partial quotients.

Expand and simplify (2x+5y) (x-3y)
Dmitry [639]
Should be simple:

Let's take this one at a time.

2x(x-3y)

You'd get:
2x^2-3xy
for the first one.

2nd one:
5y(x-3y)
you'd get:
+5xy-3y^2

Put them both together:
2x^2-3xy+5xy-3y^2

Combine like terms.

Your Answer:
2x^2+2xy-3y^2

-36 4/9 - (-10 2/9) -(18 2/9)
Degger [83]

Answer: -44\dfrac{4}{9}

Step-by-step explanation:

The given expression: -36\dfrac{4}{9}-(-10\dfrac{2}{9})-(18\dfrac{2}{9})

Here, 36\dfrac{4}{9}=\dfrac{36\times9+4}{9}=\dfrac{328}{9}

(10\dfrac{2}{9})=\dfrac{92}{9}\\\\(18\dfrac{2}{9})=\dfrac{9\times18+2}{9}=\dfrac{164}{9}

That is

-36(\dfrac{4}{9})-(-10\dfrac{2}{9})-(18\dfrac{2}{9}) = -\dfrac{328}{9}-(-\dfrac{92}{9})-\dfrac{164}{9}\\\\=-\dfrac{328}{9}+\dfrac{92}{9}-\dfrac{164}{9}\\\\=\dfrac{-328+92-164}{9}\\\\=\dfrac{-400}{9}\\\\=-44\dfrac{4}{9}

Find the volume of the composite solid. Round your answer to the nearest tenth
Llana [10]

Answer:

1131.0 m^3

Step-by-step explanation:

Let h1 represent the height of the top cone, and h2 the height of the bottom cone. The volume of a cone is given by the formula ...

V = (1/3)πr^2·h

so the volumes of both cones together will be ...

V = (1/3)πr^2·h1 + (1/3)πr^2·h2 = (1/3)πr^2·(h1 +h2)

= (1/3)π(6 m)^2(12 m + 18 m) = 360π m^3

≈ 1131.0 m^3
