A farmer sells 8.3 kg of apples and pears at the farmers market this way is apples and Restless Paris how many kilograms of Pari

Serga [27]

Answer:

She sell 2.075 kilograms of pears at the farmer's market.

Step-by-step explanation:

There is a mistake in the question some data is missing, so the correct question is below:

A farmer sells 8.3 kg of apples and pears at the farmer's market. 3 /4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?

Now, to find the kilograms of pears.

Total weight of apples and pears = 8.3 kg.

Weight of apples = $\frac{3}{4}$ of 8.3 kg.

So, to get the weight of apples:

$\frac{3}{4} \times 8.3$

$=0.75\times 8.3$

$=6.225\ kg.$

Thus, the weight of apples = 6.225 kg.

Now, to get the weight of pears we subtract the weight of apples from the total weight of apples and pears:

$8.3-6.225\\\\=2.075\ kg.$

Therefore, she sell 2.075 kilograms of pears at the farmer's market.

Stefan estimates the income and expenses for renting

Elena-2011 [213]

Answer/Step-by-step explanation:

If total income is more than total expenses, she should rent it. If the total income is less than the total expenses, she should not rent it.

Total income estimated in a month:

Sales: $950 per week = 950*4weeks = $3,800 per month

Services: $2,875 per month

Total estimated income per month = $(3,800 + 2,875) = $6,675

Total expenses estimated in a month:

Rent: $4,500 per month

Travel: $7.5 per day = 7.5*7days = $52.5 per week.

Assuming there are 4 weeks in a month, expenses for travel in a month will be:

$52.5*4 = $210

Merchandise: $1,650 per month

Total expenses estimated per month = $(4,500 + 210 + 1,650) = $6,360

Total estimated income ( > total estimated expenses in a month, therefore, Stefan should rent the phone accessory store. She will make profit.

If cosVz=0.1673413807, find Vz. Thanks- thold you it was easy.

12345 [234]

Answer:

Vz = arccos(0.1673413807) = 80.37º

Step-by-step explanation:

The inverse function of the cosine is the arc cosine.

That means, that if we have that cos a = 1, a is the angle which has cosine equals 1, so a = arccos(1) = 0º.

In this problem, we have that:

cos(Vz) = 0.1673413807

Vz = arccos(0.1673413807) = 80.37º
