8. A box is filled with candies in different colors. We have 40 white candies, 24 green ones, 12

Darya [45]

Answer:

$P(Green\ or\ Red) = 0.30$

Step-by-step explanation:

Given

$White = 40$

$Green = 24$

$Red = 12$

$Yellow = 24$

$Blue = 20$

Required

$P(Green\ or\ Red)$

The total numbe of candy is:

$Total = 40 + 24 + 12 + 24 + 20$

$Total = 120$

This probability is calculated as:

$P(Green\ or\ Red) = P(Green) + P(Red)$

For each, we have:

$P(Green\ or\ Red) = \frac{Green}{Total} + \frac{Red}{Total}$

Take LCM

$P(Green\ or\ Red) = \frac{Green+Red}{Total}$

$P(Green\ or\ Red) = \frac{24+12}{120}$

$P(Green\ or\ Red) = \frac{36}{120}$

$P(Green\ or\ Red) = 0.30$

The financial statements of the Tyler Company report net sales of $300,000 and accounts receivable of $50,000 and $10,000 at the

iragen [17]

Answer:

the accounts receivable turnover for the Tyler Company is 10

Step-by-step explanation:

The company report :

net sales = $300,000

account receivable = $50,000 and $10,000

to find the accounts receivable turnover, use the following formula:

accounts receivable turnover = net sales : average account receivable

First, we need to calculate the average account receivable of the company

average accounts receivable = ($50,000+$10,000) : 2

= $60,000 : 2

= $30,000

Then, substitute net sales into the formula

accounts receivable turnover = $300,000 : $30,000

= 10

A weight lifter does 9.8 J of work while lifting a weight straight upward through a distance of 0.12m. What was the force exerte

gulaghasi [49]

Answer:

The force exerted by the weight lifter is 81.7 N.

Step-by-step explanation:

We can find the force exerted by the weight lifter using the definition of work:

$W = F*d$ (1)

Where:

F: is the force

d: is the displacement

We have W = 9.8 J of work and d = 0.12 m, so by solving equation (1) for F we have:

$F = \frac{W}{d} = \frac{9.8 J}{0.12 m} = 81.7 N$

Therefore, the force exerted by the weight lifter is 81.7 N.

I hope it helps you!

Select all of the scales that are equivalent to 3 cm to 4 km.

ra1l [238]

In mathematics, a scale can be described in charts as a marking system at predefined times, which determines the relationship between the units that are being used and their images on the graph, and the further calculation can be defined as follows:

Since in this question, the ratio is between 3 cm to 4 km you can make a $\bold{\frac{3}{4}=\frac{cm}{km}}$ split, and if you are split between 3 and 4, you get the ratio between $\bold{\frac{\frac{3}{4 \ cm}}{1\ km} = \frac{3\ cm}{ 4\ km}}$ .

$\bold{\to \frac{3 }{ 4}= 0.75}$

Therefore the final answer is "0.75 cm to 1 km"
