Jack usually mows his lawn in 6 hours. marilyn can mow the same yard in 4 hours. How much time would it take for them to mow the

Anuta_ua [19.1K]

Answer:

2.4 hours or 2 hours and 24 minutes

Step-by-step explanation:

Jack mows 1/6 of the lawn per hour while Marilyn mows 1/4 of the lawn together. Adding up those rates yields in their combined mowing rate:

$R = \frac{1}{6}+ \frac{1}{4}\\R=\frac{10}{24}$

The time required for them to mow the entire lawn is:

$t = \frac{1}{R}\\t = \frac{1*24}{10}\\ t=2.4\ hours$

It would take them both 2.4 hours to mow the lawn together.

A cylinder of manganese (length 4.00 cm, diameter = 1.00 cm) has a mass of 22.62 g. What is the density of manganese?

Gnom [1K]

Equation for density is mass/volume

Mass=22.62 g

Volume= 22/7 x 1/2^2 x 4

3.14 x 0.5 x 0.5 x 4

=3.14 cm3

Mass/ Volume

22.62/3.14

Answer:

Independent Events

Step-by-step explanation:

Given

$Green = 3\\ Orange = 2\\ Red = 5$

Required

Dependent or independent event

The probability of selecting a green jelly remains unchanged before and after selecting the first orange jelly.

<u>Before selecting the orange jelly:</u>

$P(Green) = \frac{Green}{Total}$

$P(Green) = \frac{3}{10}$

<u>After selecting the orange jelly:</u>

$P(Green) = \frac{Green}{Total}$

$P(Green) = \frac{3}{10}$

Because the probabilities remain unchanged, the selection of a green jelly is independent of the selection of the first orange jelly.
