Answer:

The answer is (d) ⇒ [tex]pq^{2}r\sqrt[3]{pr^{2}}[/tex]

Step-by-step explanation:

* To simplify the cube roots:

 If its number then the number must be written in the form x³

 then we divide the power by 3 to cancel the radical

 If its variable we divide its power by 3 to cancel the radical

Answer: Deanna has the higher mean score by .5

Step-by-step explanation: The important piece of information to remember here is that the mean is the average. In order to solve the question, the first thing that you need to do is calculate the average of each of their scores.

Deanna = 18+20+22+25+12+20 = 117

The mean = 117/6 = 19.5

Lilly = 20+20+21+21+16+16 = 114

The mean - 114/6 = 19

[tex]lim_{x \to \: 0}( {x}^{2} - 1) = - 1[/tex]

EXPLANATION

The given limit is

[tex] lim_{x \to \: 0}( {x}^{2} - 1) [/tex]

To evaluate this limit by direct substitution,

We put x=0 in the function.

This implies that that ,

[tex] lim_{x \to \: 0}( {x}^{2} - 1) = {0}^{2} - 1[/tex]

This simplifies to,

[tex] lim_{x \to \: 0}( {x}^{2} - 1) = 0 - 1[/tex]

Answer: the answer is 189 units^2

Step-by-step explanation: Apex

The surface area of the given regular pyramid is 140 units^2, calculated using the formula Surface Area = B + 1/2Pl, where B is the base area, P is the perimeter of the base, and l is the slant height.

The surface area of a regular pyramid is calculated by adding the area of the base to the total area of the triangular faces.

The formula to calculate this is: Surface Area = B + 1/2Pl, where B is the base area, P is the perimeter of the base, and l is the slant height.

Given the dimensions, 10cm is base and 7cm as a slant height, we can calculate that the base area (B) is 100 cm2 and the perimeter (P) is 40 cm.

Plugging these values into the surface area formula, we find that the surface area is 140 cm2 (100 cm2 for the base and 140 cm2 for the triangular faces).

Therefore, the correct answer is B. 140 units2.

50x2=x

50 represents the red candies.

2 represents the other half of candies.

x represents the total amount of candies.

Hope this helps!

The equation representing the total number of candies in Meghan's jar, where x is the total, is x/2 = 50, giving us 100 candies in total. For Jenny's chocolates, Jenny initially had 14 chocolates before she ate two and gave half of the remaining to Lisa.

If Meghan discovered that half of the candies were red and she had 50 red candies, then to find the equation representing the total number of candies in the jar, we assign x to represent the total number. Since half of x is 50, the equation is x/2 = 50. To find x, we multiply both sides of the equation by 2, resulting in x = 100. Therefore, Meghan has 100 candies in total in her jar.

To address the question about Jenny and her chocolates: Initially, Jenny has some number of chocolates. When she eats two chocolates and gives half of the remainder to Lisa, and Lisa ends up with six chocolates, we can determine how many Jenny started with. Lisa's six chocolates represent half of what remained after Jenny ate two, which implies there were 12 before giving to Lisa, and so initially, Jenny had 14 chocolates.

Answer:

36÷(6÷3) = 18

Step-by-step explanation:

First, you would solve what is in the parentheses.

36÷(6÷3) = 36÷(2)           Now, find 36÷2

               = 36÷2 = 18

so, 36÷(6÷3) = 18

The number of angles that are alternate exterior angles with angle 5 is equal to 1.

In Mathematics,  parallel lines are two lines that are cut through by a transversal and they always have the same (equal) distance apart and never meet.

In Mathematics, the alternate exterior angle theorem states that when two (2) parallel lines are cut through by a transversal, the alternate exterior angles that are formed lie outside the two (2) parallel lines, are located on opposite sides of the transversal, and are congruent angles.

In conclusion, we can logically deduce that both m∠5 and m∠11 are alternate exterior angles because they lie outside the two (2) parallel lines and are located on opposite sides of the transversal.

Answer:

8 - 2x

Step-by-step explanation:

|2x -8| , x < 4

Two conditions:

(a) |2x - 8| =   (2x - 8) if (2x - 8) ≥ 0

(b) |2x - 8| = -(2x - 8) if (2x - 8) < 0

If x < 4, (2x - 8) <0, so condition (b) applies.

|2x - 8| = -(2x - 8) or

|2x - 8| = 8 - 2x

The equivalent expression is 8 - 2x.

Last option: [tex]A=2\pi rh[/tex]

Step-by-step explanation:

 If  the shell of a bass drum was cut down one side and laid flat, the resulting shape would be a rectangle.

The area of a rectangle can be calculated with the formula:

[tex]A=l*w[/tex]

Where l is the lenght and w is the width.

In this case, the lenght of the rectangle obtained (the lenght of the shell)  is the circumference of the drum.

Remember that the circumference of the circle can be calculated with:

[tex]C=2\pi r[/tex]

Where r is the radius of the circle.

Then:

[tex]l=2\pi r[/tex]

The width is the height of the shell:

[tex]w=h[/tex]

Then, substituting into [tex]A=l*w[/tex], you get:

[tex]A=2\pi rh[/tex]

Step-by-step explanation:

Assuming you are asking for congruent parts, correspondence is the part which corresponds and is also equal.

Here Angle O is equal to Angle O as they are vertical angles across a vertex.

Answer:

The correct option is 2.

Step-by-step explanation:

From the given figure it is clear that the lines DE║RK, in triangle ODE and triangle OKR,

[tex]\angle DOE=\angle KOR[/tex]                         (Vertical opposite angles)

[tex]\angle ODE=\angle OKR[/tex]                         (Alternate interior angles)

[tex]\angle OED=\angle ORK[/tex]                         (Alternate interior angles)

By using AA property of similarity,

[tex]\triangle DOE\sim \triangle KOR[/tex]

D is correspondence to K, O is correspondence to O, E is correspondence to R.

O ↔ O

Therefore the correct option is 2.

Start with definition of absolute value, |x|.

It says,

|x| = x, for any x >= 0 and

|x| = -x, for any x < 0

Now, instead of x, we have the expression x+120 inside the absolute value brackets:

|x+120|

Play the same game as above - what is the absolute value here?

|x+120| = x+120 for (x+120)>=0 and

|x+120| = -(x+120) for (x+120)<0

Now, recognize that the last condition (x+120)<0 is the same as writing x<-120. That is the condition in the question. Therefore the absolute value |x+120| will equal the second expression (for that condition), namely -(x+120), or -x-120.

To simplify |x + 120| when x is less than -120, you change the sign of the expression inside the absolute value to get the simplified form as -x - 120.

To simplify |x + 120| when x < -120, we need to consider the definition of absolute value. The absolute value of a number is the non-negative value of that number without regard to its sign. Since x is less than -120, x + 120 is a negative number, and to find its absolute value, we change the sign to positive.

Therefore, the simplification of |x + 120| when x < -120 is simply -(x + 120), which equals -x - 120.

Answer:

615.6

Step-by-step explanation:

First find the number of cubic feet.

V = B * h

B is a triangle with a right angle on your left and two 6 foot lengths on each leg.

Area = 1/2 b * h

b = 6 feet

h = 6 feet

Area = 1/2 * 6 * 6 = 18 square feet.

The volume = B * h

h = 11.4

B = 18 sq ft

Volume = 18 * 11.4

Volume = 205.2 Cubic Feet.

Each cubic foot costs 3.00 dollars

Cost = volume * cost/cu foot

Cost = 205.2 * 3

Cost = 615.6
