A 40 kg-skier is standing at the top of a 12-meter high slope. What is her potential energy? PE = m x g x h (g = 10m/s2) A. 6000J B. 48J C. 4800J D. 400J

Answers

Answer 1

Answer:

The correct option is;

C. 4800 J

Step-by-step explanation:

The given parameters are;

The mass of the skier = 40 kg

The height of the slope = 12 meter

The acceleration due to gravity, g = 10 m/s²

The potential energy, PE, is given by the formula PE = Mass, m × Acceleration due to gravity, g × Height, h

Substituting the values, gives

The potential energy, PE = 40 kg × 10 m/s² × 12 m = 4800 kg·m²/s² = 4800 J

The potential energy, PE = 4800 J

C) the triangles are congruent

Step-by-step explanation:

Answer:

c. the triangles are congruent

Step-by-step explanation:

Both the triangles are right triangles which means the square thing at the bottom corner of the triangles are 90 degrees. So with this info, a triangle is 180 degrees, and one of the triangles already gave u one of the corners degrees so

90 + 59 + x =180

149 + x = 180

x = 31, so now the left triangle is solved. Now see the 118 degrees in the middle? A straight line is 180 degrees so with this in mind,

31 + 118 + x = 180

149 + x = 180

x = 31

The right triangle also has 31 and 90 as two of its angles, we don't need to calculate to know the last angle left is 59 like the left triangle. Therefore both triangles are congruent as they are the same.

A gum ball has a radius that is 30mm. The radius of the gumballs spherical hollow core is 28mm. What is the volume of the gum ball if you do not include it's hollow core

Answers

Answer:

V = 21145.01 mm³

Step-by-step explanation:

Given that:

The radius of the gumball = 30  mm

The radius of the spherical hollow-core = 28 mm

Consider the radius of the gumball to be [tex]r_2[/tex] and the radius of the spherical hollow-core to be [tex]r_1[/tex]. Then;

The volume of the gumball can be determined by using the formula of a sphere.

[tex]V = \dfrac{4}{3}\pi (r_2^3 - r_1^3)[/tex]

[tex]V = \dfrac{4}{3} \times \pi \times (30^3 - 28^3)[/tex]

V = 21145.01 mm³

The required mass of an object is 512g.

Given that,
The density of 8 g/cm3 and a volume of 64 cm3,
The mass of the object is to be determined.

What is volume?

Volume is defined as the ratio of the mass of an object to its density.

What is simplification?

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Here,
Mass = density * volume
Mass = 8 * 64
Mass = 512 g

Thus, the required mass of the object has density of 8 g/cm3 and a volume of 64 cm3.

Delta Company produces a single product. The cost of producing and selling a single unit of this product at the company's normal activity level of 88,800 units per year is: Direct materials $ 1.50 Direct labor $ 3.00 Variable manufacturing overhead $ 0.50 Fixed manufacturing overhead $ 4.45 Variable selling and administrative expenses $ 1.30 Fixed selling and administrative expenses $ 2.00 The normal selling price is $21.00 per unit. The company's capacity is 112,800 units per year. An order has been received from a mail-order house for 2,000 units at a special price of $18.00 per unit. This order would not affect regular sales or the company's total fixed costs

Answers

Answer:

The company should accept the special offer because it increases income by $23,400.

Step-by-step explanation:

Giving the following information:

Variable costs:

Direct materials $1.50

Direct labor $3.00

Variable manufacturing overhead $0.50

Variable selling and administrative expenses $1.30

Total variable cost= $6.3

An order has been received from a mail-order house for 2,000 units at a special price of $18.00 per unit.

Because it is a special offer and there is unused capacity, we will not take into account the fixed costs:

Effect on income= number of units*unitary contribution margin

Effect on income= 2,000* (18 - 6.3)

Effect on income= $23,400 increase

The company should accept the special offer because it increases income by $23,400.

Step 2: Simplify: 21

                             0

Answer: Undefined. Vertical line on graph.

Answer: 21

Step-by-step explanation: The first thing you should have noticed is that x is the same for both coordinates; in other words, x=17, which means there's no change and x, and it will therefore be a straight vertical line. From there, you can find the change in y to determine the slope (because slope is rise over run). Since 8-(-13)=21, the slope is 21.
