The total surface area of the solid cone, given the slant height and the radius, would be 374 m².

To find the surface area of a solid cone, we need to consider both the curved lateral surface and the circular base.

Lateral Surface Area = π x 7 m x 10 m = 70π m²

The base of a cone is a circle with radius r. The area of the base can be calculated using the formula:

Base Area = π x (7 m)² = 49π m²

Total Surface Area = Lateral Surface Area + Base Area = 70π m² + 49π m² = 374 m².

Step-by-step explanation:

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.

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

Answer:

The error in Amanda's calculation is in line 2, where she incorrectly subtracted 6x instead of adding 6x, as well as incorrectly subtracting 24 instead of adding 24.  Amanda also omitted the addition sign in line 3 of her calculations.

Step-by-step explanation:

To factor a quadratic polynomial in the form ax² + bx + c, find two numbers that multiply to ac and sum to b.

Therefore, for the given polynomial 4x² + 22x + 24:

⇒ ac = 4 · 24 = 96

⇒ b = 22

The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96.

Therefore, the factor pair that sums to 22 is 16 and 6.

Rewrite b as the sum of these two numbers:

⇒ 4x² + 22x + 24

⇒ 4x² + (16 + 6)x + 24

⇒ 4x² + 16x + 6x + 24

Therefore, the error in Amanda's calculation is in line 2, where she incorrectly subtracted 6x instead of adding 6x, as well as incorrectly subtracting 24 instead of adding 24.  Amanda also omitted the addition sign in line 3 of her calculations.

The correct calculation is as follows:

   4x² + 22x + 24

⇒ 4x² + 16x + 6x + 24

⇒ 4x(x + 4) + 6(x + 4)

⇒ (4x + 6)(x + 4)

Given :-

To find:-

Answer:-

Given polynomial to us is ,

[tex]\implies 4x^2 + 22x + 24 \\[/tex]

With respect to the standard form of polynomial ax² + bx + c , we have;

Step 1 :- Split the middle term into two parts p and q such that p × q = a × c and p + q = b

Such two numbers are 16 and 6 .

Hence, we can rewrite it as ,

[tex]\implies 4x^2 + 16x + 6x + 24 \\[/tex]

But Amanda wrote [tex] 4x^2+16x - 6x + 24[/tex] , so she made a mistake here by writing +6x as -6x .

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 total area of gray sections of the target is  1017 square inches. The correct option is (D).

To find the total area of the gray sections of the target, we need to first find the areas of the gray rings. We can do this by subtracting the area of the smaller circle from the area of the larger circle for each ring.

The area of a circle is given by the formula A = πr^2, where r is the radius.

For the outer gray ring, the radius is 1.5 feet. So, the area of the gray ring is:

A_gray_outer = π(1.5)^2 - π(1)^2

= 7.06858 - 3.14159

= 3.92699 square feet

For the middle gray ring, the radius is 1 foot. So, the area of the gray ring is:

A_gray_middle = π(1)^2 - π(0.5)^2

= 3.14159 - 0.78540

= 2.35619 square feet

For the inner gray ring, the radius is 0.5 feet. So, the area of the gray ring is:

A_gray_inner = π(0.5)^2 - 0

= 0.78540 square feet

The total area of the gray sections of the target is the sum of these three areas:

A_total_gray = A_gray_outer + A_gray_middle + A_gray_inner

= 3.92699 + 2.35619 + 0.78540

= 7.06858 square feet

To convert this to square inches, we multiply by the conversion factor (12 inches/foot)^2:

A_total_gray = 7.06858 * (12)^2

= 1016.7048 square inches

Rounding this to the nearest square inch gives:

A_total_gray ≈ 1017 square inches

So the correct answer is (D). 1017 square inches.

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.

[tex]R = 8/17\\S = 15/17[/tex]

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.

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.

Two of the angles in an isosceles triangle are identical in size, while the third angle varies.

We need to first create a frame of reference in order to determine how many unit angles the smaller angle of a small pattern block turns through.

Assume that we begin by placing the little pattern block in its initial location with one of its sides vertically aligned.

This results in one of the isosceles triangles being vertically aligned after turning the block.
