The area of the equilateral triangle with side length 2cm is approximately 1.73 cm².

An equilateral triangle with side length 2cm can be divided into two right triangles with hypotenuse equal to 2cm and the other two sides of length 1cm each.

We can then use the Pythagorean theorem to find the length of the height of the equilateral triangle, which is also the height of the right triangles.

Let h be the height of the equilateral triangle, then:

h² = 2² - 1²

h² = 3

h = √3

The area of the equilateral triangle can be found using the formula:

Area = (base × height) / 2

Since the equilateral triangle has three equal sides, the base is also equal to 2cm. Therefore, we have:

Area = ( 2 × √3 ) / 2

Area = √3

Rounding to the nearest hundredth, we get:

Area = 1.73 cm²

Therefore, the area of the equilateral triangle is  1.73 cm².

Answer:

D

Step-by-step explanation:

To calculate the percentage decrease in price, we need to find the difference between the original price and the reduced price, divide that difference by the original price, and then multiply by 100 to express it as a percentage.

The original price of the iPhone was $320, and it was reduced to $224. Therefore, the difference between the two prices is:

$320 - $224 = $96

To find the percentage decrease, we divide this difference by the original price:

$96 ÷ $320 = 0.3

Finally, we multiply this result by 100 to express it as a percentage:

0.3 × 100 = 30%

Therefore, the answer is D. The price of the iPhone was reduced by 30%.

The formula for this specific shade of orange paint is 3 parts yellow for every 2 parts red. To calculate the amounts of red and yellow paint that can be used for different combinations we can use the following equation:

Yellow = 2 x Red/3

For the first combination of 2 parts red and 3 parts yellow, the equation can be written as:

Yellow = (2 x 2)/3

Simplified, that is 2/3, or 3 parts yellow.

For the second combination of 4 parts red and 6 parts yellow, the equation can be written as:

Yellow = (2 x 4)/3

Simplified, that is 4/3, or 6 parts yellow.

For the third combination of 6 parts red and 9 parts yellow, the equation can be written as:

Yellow = (2 x 6)/3

Simplified, that is 8/3, or 9 parts yellow.

For the fourth combination of 8 parts red and 12 parts yellow, the equation can be written as:

Yellow = (2 x 8)/3

2.)

[tex]R = 5/13[/tex]

[tex]S=12/13[/tex]

Step-by-step explanation: sin represents the ratio between a side opposite to an angle and the hypotenuse. It is important to learn these ratios as they allow for you to solve for side lengths in a triangle and angles. We were in this case finding the ratios. A lowercase letter represents a side length opposite to the angle. So to find R we would just need to divide r by t. In the first example, it would just be 16/34 which simplifies to 8/17. Do the same thing for s, and it would be for 30/34 which simplifies to 15/17. Repeat the same steps and you should get 5/13 for R and 12/13 for S.

The resistance of the coil is given by R = N x ρL = 70 x ρ x 0.0897 = 617.9 x ρ ohms.

The length of the wire is equal to the circumference of the circular coil. The circumference C of a circle of radius r is C = 2πr, so for the circular coil of radius 1m, the length of the wire is 2π x 1m = 6.28m.

The number of loops around the coil (N) is 70. Therefore, the length of one loop is L = 6.28/70 = 0.0897 m.

The resistance of the coil (R) is equal to the resistance of the single loop multiplied by the number of loops (N). Therefore, R = N x R', where R' is the resistance of a single loop.

The resistance of a single loop is equal to the resistance of the wire per unit length multiplied by its length. Therefore, R' = ρL, where ρ is the resistivity of the wire and L is the length of one loop of the wire.

Assuming that ∠1 and its adjacent angle form a straight line, we know that the sum of the angles on a straight line is 180°. Therefore, the measure of the adjacent angle is 180° - 39° = 141°.

we can also look at the other angles in the figure. From the diagram, we can see that ∠2 and ∠3 are acute angles, which means they are less than 90°. Additionally, we know that the sum of the angles in a triangle is 180°, so ∠2 + ∠3 + ∠4 = 180°.

Since ∠2 and ∠3 are acute, their sum must be less than 180°. Therefore, ∠4 must be an obtuse angle (greater than 90°) in order for the sum to be 180°. This makes sense, as an obtuse angle is required to form a triangle with two acute angles.

Janella recognizes a gain of $36,000 and her basis in the distributed property is $54,000.

Janella's basis in her partnership interest is $120,000, which includes her share of partnership debt. When the partnership pays off its debts and liquidates, Janella receives a proportionate liquidating distribution consisting of $42,000 cash and inventory valued at $24,000 (adjusted basis to the partnership = $20,000).

To calculate Janella's recognized gain or loss, we need to compare her basis in the partnership interest to the fair market value of the distributed assets.

The fair market value of the distributed assets is $42,000 (cash) + $24,000 (inventory) = $66,000.

The amount of the loss is the excess of her basis over the fair market value of the distributed assets, which is $120,000 - $66,000 = $54,000.

To determine Janella's basis in the distributed property, we need to adjust her basis in the partnership interest by the amount of the liquidating distribution she received.

Janella received a total liquidating distribution of $42,000 cash + $24,000 inventory = $66,000. Her share of partnership debt was $150,000, and the partnership paid off all its debts, so she no longer has any debt basis.

Janella's distribution of $66,000 exceeds her adjusted basis of $30,000 by $36,000. She recognizes a gain of $36,000. Therefore, Janella's new basis in the distributed property is $120,000 - $66,000 (liquidating distribution) = $54,000.

The direction of the resulting force upon the piling is approximately 298.85 degrees

We can use vector addition to find the direction of the resulting force. Let's call the force exerted by the first bulldozer F1, and the force exerted by the second bulldozer F2. We can represent each force as a vector with a magnitude and direction.

F1 has a magnitude of 1850 pounds and points in a westerly direction. We can represent it as a vector (-1850, 0).

F2 has a magnitude of 3250 pounds and points in a northerly direction. We can represent it as a vector (0, 3250).

To find the resulting force, we need to add these two vectors. We can do this by adding the x-components and the y-components separately.

The x-component of the resulting force is -1850 (from F1) plus 0 (from F2), which is -1850.

The y-component of the resulting force is 0 (from F1) plus 3250 (from F2), which is 3250.

So the resulting force is a vector with components (-1850, 3250). We can find the direction of this vector by taking the inverse tangent of the ratio of the y-component to the x-component.

tan(theta) = (3250) / (-1850)

theta = -61.15 degrees

The negative sign indicates that the resulting force points to the southwest. To get the angle in the range of 0 to 360 degrees, we can add 360 degrees to the angle if it is negative.

theta = 360 - 61.15

theta = 298.85 degrees

Using hypothesis testing, the critical value of z for a 5 percent level of significance, left-tailed test is -1.645.

(a) For a 10 percent level of significance, two-tailed test, the critical value of z is:

z_critical = ± invNorm(1 - (0.10/2))

where invNorm is the inverse normal cumulative distribution function. Evaluating this expression gives:

z_critical = ± 1.645

Therefore, the critical value of z for a 10 percent level of significance, two-tailed test is ±1.645.

(b) For a 1 percent level of significance, right-tailed test, the critical value of z is:

z_critical = invNorm(1 - 0.01)

Evaluating this expression gives:

z_critical = 2.326

Therefore, the critical value of z for a 1 percent level of significance, the right-tailed test is 2.326.

(c) For a 5 percent level of significance, left-tailed test, the critical value of z is:

z_critical = invNorm(0.05)

We can predict that in 120 tries, we would expect to get heads and an odd number around 30 times. However, it is important to note that this is just a prediction and the actual number of times this occurs may vary due to chance.

When flipping a dime, there are two possible outcomes: heads or tails. Similarly, when rolling a die, there are six possible outcomes: 1, 2, 3, 4, 5, or 6. An odd number is any number that is not divisible by 2, so the odd numbers on a die are 1, 3, and 5.

The probability of flipping heads on a dime is 1/2, and the probability of rolling an odd number on a die is 3/6 or 1/2. To predict how many times you would flip heads and roll an odd number in 120 tries, we can use the multiplication rule of probability.

The multiplication rule of probability states that the probability of two independent events occurring together is the product of their individual probabilities. Since flipping a dime and rolling a die are independent events, we can multiply the probability of flipping heads and the probability of rolling an odd number to get the probability of both events occurring together.

So, the probability of flipping heads and rolling an odd number is:

P(heads and odd) = P(heads) x P(odd)

P(heads and odd) = (1/2) x (1/2)

P(heads and odd) = 1/4

We can estimate that in 120 trials, we should get heads about 30 times and an odd amount about the same. It is crucial to keep in mind that this is only a prediction and that there is a possibility that the actual frequency of occurrence will differ.

The character '=' connects the two expressions. An equation is a mathematical formula that has two algebras on each side of an assignment operator (=). It demonstrates the equivalency link between the left and middle formulas. L.H.S. = R.H.S. (left side = right side) in any formula.

We can see from the diagram that PQ is parallel to BC and that the line segments PQ and BC overlap at point O.

As a result, we have:

angle QPO stands for angle. 70° angle = ABC QOP stands for angle. ACB = 110°

angle AOB = angle - 180 ACB - ABC angle = 180 - 70 - 110 = 0

This indicates that points A, O, and B are collinear and that angle AOB is a straight angle, implying that angles AOP and POB are supplementary angles.

We may use this data to calculate the value of x:

AOP angle + POB angle = 180

(3x - 10) + (2x + 20) = 180

5x + 10 = 180
