Answer:

False

Step-by-step explanation:

A line is defined by and consists of at least two points, therefore, an extra point in the same plane can be located such that when joined to one of the previous two points to form another distinct line

However, three points can only lie on one distinct plane as the location of the third point together with the two colinear point form either three colinear points or a triangle which is a planar two dimensional polygon.

Answer:

Step-by-step explanation:

To answer, we have to find the base unit of how much each package would cost out of a box. To do this, we divide the total amount of the box of paper by how many packages were inside:

40 / 8 = 5

So, each package costed Ms. Jones $5, while the single packages cost $5.50, so Ms. Jones saved $0.50 per package she bought, which if you multiply by 8, you get 4, so Ms. Jones saved a total of $4.

Hope this helps :)

hodyreva [135]

Answer:

Approximately 104 joggers are female

Step-by-step explanation:

The U.S census bureau reported that 9 out of every 20 joggers at female.

Let x be the number of females out of 230 joggers.

Rewrite it as

$\begin{array}{cc}\text{Female}&\text{All joggers}\\9&20\\x&230\end{array}$

Now we can write a proportion:

$\dfrac{9}{x}=\dfrac{20}{230}$

Cross multiply:

$20x=9\cdot 230\\ \\2x=9\cdot 23\ [\text{Divided by 10}]\\ \\x=\dfrac{9\cdot 23}{2}=\dfrac{207}{2}=103.5\approx 104$

Answer:

see explanation

Step-by-step explanation:

Given that M is directly proportional to r³ then the equation relating them is

M = kr³ ← k is the constant of proportion

To find k use the condition when r = 4, M = 160, thus

160 = k × 4³ = 64k ( divide both sides by 64 )

2.5 = k

M = 2.5r³ ← equation of variation

(a)

When r = 2, then

M = 2.5 × 2³ = 2.5 × 8 = 20

(b)

When M = 540, then

540 = 2.5r³ ( divide both sides by 2.5 )_

216 = r³ ( take the cube root of both sides )

r = $\sqrt[3]{216}$ = 6
