Answer:

9.42m

Step-by-step explanation:

You have to find the circumference using C=2πR. We know that the radius =4 meters so then we can insert it into the formula to get the circumference which equals 8π. Then we divide 24m² by 8πm and get 9.42m.

polet [3.4K]

Using statistical concepts, it is found that the number of outcomes that are possible for the complement of the union of Events J and K is of 43.

<h3>What is the union of events J and K?</h3>

It means that at least one of event J or event K is true, hence, it is composed by employees that are either considered support staff(less than 5 years of experience) or employees that have more than five years of experience, combining a total of 7 + 8 = 15 employees.

<h3>What is the complement?</h3>

The total number of outcomes of the union of J and K, plus the complement, add to the total number of 58, hence:

15 + x = 58

x = 43.

The number of outcomes that are possible for the complement of the union of Events J and K is of 43.

A company spends 13% of its month budget on rent which total $2600 which proportion can be used to calculate the company’s total
yaroslaw [1]

Answer:

20,000

Step-by-step explanation:

We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.

\frac{13}{100} =\frac{2600}{x}


We begin solving by cross multiplying numerator to denominator of each fraction.


13(x)=100(2600)\\13x=260000\\\frac{13x}{13}=\frac{260000}{13}  \\20,000=x

2(vh)/k=r Solve equation for v in terms of all other variables involved
aivan3 [116]

The equation v in terms of other variables is v = kr/2h

<h3>What is the subject of an equation?</h3>

It is a variable which is expressed in terms of other variables involved in the formula.

Formulas are written so that a single variable, the subject of the formula is on the L.H.S. of the equation. Everything else goes on the right side of the equation. We evaluate the formula by substituting for the literal numbers on the right hand side.

2(vh) / k = r

by cross multiplication

2(vh) = kr

divide both sides by 2h

v = kr/2h

In conclusion, v in terms of other variables is  kr/2h

43x+2 = 64 + 455 - 766
Rudik [331]

43x+2=64+455−766

Step 1: Simplify both sides of the equation.

43x+2=64+455−766

43x+2=64+455+−766

43x+2=(64+455+−766)(Combine Like Terms)

43x+2=−247

43x+2=−247

Step 2: Subtract 2 from both sides.

43x+2−2=−247−2

43x=−249

Step 3: Divide both sides by 43.

43x /43  =  −249 /43

x =  −249 /43

Answer:

x =  −249 /43
