Answer:

$\sqrt{97}$

Step-by-step explanation:

$|a + bi| = \sqrt{a^2 + b^2}$

$|-4 - 9i| = \sqrt{(-4)^2 + (-9)^2}$

$|-4 - 9i| = \sqrt{16 + 81}$

$|-4 - 9i| = \sqrt{97}$

Kevin and Randy Muise have a jar containing 46 coins, all of which are either quarters or nickels. The total value of the coins

Zepler [3.9K]

Answers:

24 quarters

22 nickels

==========================================================

Work Shown:

q = number of quarters

n = number of nickels

q+n = 46 coins total which solves to n = 46-q

25q = value of all the quarters in cents

5n = value of all the nickels in cents

25q+5n = value (cents) of all the coins of both types

25q+5n = 710 cents total = $7.10

-------------

Apply substitution.

25q+5n = 710

25q+5(46-q) = 710

25q+230-5q = 710

20q+230 = 710

20q = 710-230

20q = 480

q = 480/20

q = 24

They have 24 quarters

This yields 25*q = 25*24 = 600 cents = $6.00 so far.

Use that value of q to find n

n = 46-q

n = 46-24

n = 22

They also have 22 nickels.

They have an additional 5n = 5*22 = 110 cents = $1.10

In total, they have 6.00+1.10 = 7.10 dollars which confirms we have the correct coin counts. Also, q+n = 24+22 = 46.

Ann, Bob, Carol, and Denis own a candy store. After a large argument, they decide to dissolve their partnership using the sealed

MaRussiya [10]

Answer:

Following are the solution to the given points:

Step-by-step explanation:

$Ann=\$3,20,000\\\\Bob=\$4,40,000\\\\Carol=\$240,000\\\\Denis= \$4,00,000\\\\$

Each player's offer divided by the total number of players calculates the fair share

Ann's fair share $= \frac{\$320,000}{4} = \$80,000\\\\$

Bob's fair share $= \frac{\$440,000}{4} = \$110,000\\\\$

Carol's fair share $= \frac{\$240,000}{4} = \$60,000\\\\$

Denis's fair share $= \frac{\$400,000}{4} = \$100,000\\\\$

Because Bob has the highest bid, that receives in the business.

Payments:

Ann $\$80,000$ paid by estate

Bob $= \$440,000 - \$110,000 = \$330,000$ owes estate

Carol $= \$60,000$ paid by estate

Denis $= \$100,000$ paid by estate

Surplus $= \$330,000 - (\$80,000+\$60,000+ \$100,000) = \$90,000$

Splitting the equally among the four players. therefore one of the each receives:

$\frac{\$90,000}{4}= \$22,500$

The final settlement of the Ann receives:

$= \$80,000+ \$22,500 = \$102,500$

Which of the following statements is true about the graph and the shading of the inequality

andreyandreev [35.5K]

Answer:

The graph is a solid line, and the shading is above the line.

Step-by-step explanation:

Given

$x + y \ge 1$

Required

Describe the graph of the inequality

We have:

$x + y \ge 1$

Subtract x from both sides

$y \ge 1-x$

The sign $\ge$ implies that the graph has a solid line

The sign $\ge$ which means greater than or greater also implies that the upper region is shaded

The mean weight of 3 people in a lift was 68kg. If 2 of them weighed 58kg each, how much did the third person weigh?

rusak2 [61]

Answer:

88kg

Step-by-step explanation:

Mean= sum of weights/ Number of people

or, 68= 58+58+x/3

or, 68 * 3= 58+58+x

or, 204=116+x

or, x= 204-116

or,x= 88

Therefore, the weight of third person was 88 kg
