Two brothers, Mark and Charles, each inherit $31000. Mark invests his inheritance in a savings account with an annual return of
Nutka1998 [239]

Answer:

$1,085

Step-by-step explanation:

Data provided in the question:

Amount inherited and invested i.e principle = $31,000

Annual return for Mark on savings account = 2.9% = 0.029

Annual return for Charles on CD = 6.4% = 0.064

Now,

The Interest earned by Mark in 1 year = principle × Rate × Time

= $31,000 × 0.029 × 1

= $899

The Interest earned by Charles in 1 year = principle × Rate × Time

= $31,000 × 0.064 × 1

= $1,984

Therefore,

More Money that Charles have than Mark = $1,984 - $899

= $1,085

In the right triangle shown, m\angle A = 30\degreem∠A=30°m, angle, A, equals, 30, degree and AB = 12\sqrt{3}AB=12
fiasKO [112]

Answer: Line AC = 24 units and line BC = 12 units.

Step-by-step explanation: Please refer to the diagram attached for more details.

The right angled triangle ABC has been drawn with angle A measuring 30 degrees and line AB measuring 12√3. To calculate the other two unknown sides AC labelled b, and BC labelled a, we shall use the trigonometric ratios. However, in this scenario, we shall apply the special values of each trigonometric ratio. These are shown in the box on the top right in the picture. The proof is given in the second right angled triangle at the bottom part of the attached picture.

Assume an equilateral triangle with lengths 2 units on all sides and 60 degrees at all angles. Drawing a line perpendicular to the bottom line would divide the top angle into two equal halves (30 degrees each), and the bottom line also would be divided into two equal halves (1 unit each). So the hypotenuse will measure 2 units and the line at the base would measure 1 unit. By using the Pythagoras' theorem, we derive the third side to be √3 <u>(that is x² = 2² - 1², and then x² = 4 - 1,  and then x² = 3 and finally x = √3).</u>

Therefore, in triangle ABC, using angle 30 as the reference angle, to calculate side AC;

Cos 30 = Adjacent/Hypotenuse

Cos 30 = (12√3)/b

b = (12√3)/Cos 30

Where Cos 30 is √3/2

b = (12√3)/√3/2

b = (12√3) * 2/√3

b = 12 * 2

b = 24

To calculate side BC;

Tan 30 = Opposite/Adjacent

Tan 30 = a/(12√3)

Tan 30 * 12√3 = a

Where Tan 30 = 1/√3

(1/√3) * 12√3 = a

12 = a

Therefore, the missing lengths in the right triangle are

AC = 24 units and BC = 12 units

Calvin took his friends to a movie for his birthday. The movie tickets cost $12 per person. He spent less than $180.If x is the
Alenkinab [10]
The inequality should be
12 \leqslant 12x  < 180
The sign on the right is only a 'smaller than' sign because he spent less than 180.
On the left, assuming that even if Calvin took nobody (poor Calvin), we should assume that he at least went himself, hence he spent a minimum of $12.
