Answer:

e) 15 N object on Mars

d) 15 N object on earth

b) 2.75 lbm object on the moon

a) 1 kg object on earth

c) 1.25 lbf object on the moon

Step-by-step explanation:

Mass is the amount of mass that a certain object has, it differs from its weight because the weight depends of the gravity or the force that is been applied to the object towards the planet.

To obtain the mass a 15N object on mars you have to divide the 15N by the gravity of mars this would be like this:

Mass:[tex]\frac{15}{3.7}[/tex]= 4.05kg

To obtain the mass of a 15 N objecto on the earth you divide 15N by 9.8 [tex]\frac{m}{s^{2} }[/tex] which is the gravity on earth.

Mass:[tex]\frac{15}{9.8}[/tex]= 1.53 kg

To calculate the mass of a 2.75 lbm object on the moon you just have to convert it to kg.

Mass in kg: 2.75*.453= 1.24  kg

Then the 1 kg mass object on the earth.

And last the 1.25 lbf object on the moon you just convert it to kilograms.

Mass in kg: 1.25*.138=.172kg

Answer:

150 minutes

Step-by-step explanation:

Since your solving for minutes you need to change the 2.5 hours into minutes. There is 60 minutes in 1 hour. you take 60 and multiply it by 2.5 because you need to find the total minutes. When you multiply those teo you get 150 minutes. Please give me the brainliest answer.

Answer:

The graph is attached below

Step-by-step explanation:

The function has three asymptotes. Before we can graph the function, we can find them.

Vertical asymptotes in the values that make the denominator zero.

The denominator becomes zero in:

[tex]x = -2\\x = 1\\[/tex]

Then the vertical asymptotes are the lines

[tex]x = -2\\x = 1\\[/tex]

The horizontal asymptote is found using limits

[tex]\lim_{x\to \infty}\frac{(2x+3)(x-6)}{(x+2)(x-1)}[/tex]

Then:

[tex]\lim_{x\to \infty}\frac{(2x^2-12x +3x -18)}{x^2-x+2x-2}[/tex]

We divide the numerator and the denominator between the term of greatest exponent, which in this case is [tex]x ^ 2[/tex]

The terms of least exponent tend to 0

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

The function has a horizontal asymptote on y = 2 and has no oblique asymptote

Answer:

Diameter 16, radius 7, circumference 37.68, diameter 8

Step-by-step explanation:

Largest area will be in a circle with the largest radius. So let's find all radii.

d = 8, so r = 4;

r = 7;

circumference = 2pi*r = 37. 68, so r = 6

diameter 18, so r = 8

Answer:

option(b)

9/13

Step-by-step explanation:

Given the expression

[tex]\frac{2n+7n}{13n}[/tex]

=[tex]\frac{9n}{13n}[/tex]

n will cancel out on both sides

so,

9/13 will remain

As 9/13 is a constant so any value of n when approaches to a constant will not affect it. Hence limit = 9/13

The limit of a constant function is equal to the constant.

Answer is ( 2, -2 ) so x=2 and y=-2

Answer:

(2,-2)

Step-by-step explanation:

This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations. It may be solved by substitution in that one of the variable is made the subject of the equation and the result is substituted into the second equation.

Given that Y = 7x – 16, y = 2(2x – 5)

Equating both equations

7x - 16 = 4x - 10

7x -4x = 16 - 10

3x = 6

x = 2

Substituting the value of x into Y = 7x – 16

y = 7(2) - 16

y = 14 - 16

y = -2

hence

(x,y) = (2,-2)

Answer: The wavelength of red light is 2 times longer than the wavelength of violet light.

Step-by-step explanation:

Let be "x" the number of times the wavelength of red ligth is longer than the wavelength of violet light.

Knowing that the wavelength (measured in meters) of red light is about [tex]8*10^{-7}[/tex] and the wavelength (measured in meters) of violet light is [tex]4*10^{-7}[/tex], you have to:

Divide the wavelength of red light (measured in meters) by the wavelength of violet light (measured in meters).

Then:

[tex]x=\frac{wavelength\ of\ red\ light}{wavelength\ of\ violet\ light}\\\\x=\frac{8*10^{-7}}{4*10^{-7}}[/tex]

Remember the Quotiend of powers property:

[tex]\frac{b^m}{b^n}=b^{(m-n)}[/tex]

Then:

[tex]x=2[/tex]

The wavelength of red light is 2 times longer than the wavelength of violet light.

4√34

Step-by-step explanation:

Given in the question is a right angle triangle

height of triangle = 20 cm

base of triangle = 12 cm

To find the length of missing side of the triangle we will use pythagorus theorem

hypotenuse² = 20² + 12²

hypotenuse² = 400 + 144

hypotenuse²  = 544

take square root on both sides

√hypotenuse² = √544

hypotenuse = 4√34 cm

Hence,  the length of missing side of the triangle is4√34 cm

Final answer:

To find the markup amount for the television, we can calculate 25% of the cost price. The markup amount is $112.50.

Explanation:

To find the markup amount, we need to determine the difference between the selling price and the cost price. The store sells items for 75% of the cost price, which means they have a markup of 25%.

To find the markup amount for the television, we can calculate 25% of the cost price.

Markup amount = 25% x $450 = $112.50

Answer:

The Original Price of the Winter Jacket is $70

Step-by-step explanation:

The Original Price is calculated by using the given information on a Simple Rule of Three formula, which looks like the following.

X --------> 100%

$52.50 --------> 75%

The Rule of Three simply asks if $52.50 is 75% then What is 100%? We solve the Rule of Three by multiplying $52.50 by 100 and then dividing the result by 75.

[tex]X = \frac{52.50*100}{75}[/tex]

[tex]X = 70[/tex]

According to the formula the Original Price of the Winter Jacket was $70

Answer:

[tex]35x - \frac{9x^2}{2} + C[/tex]

Step-by-step explanation:

The antiderivative of the function is the same as the integral. To find the integral or antiderivative, reverse the process of differentiation method. Currently the function has degree 1. Through integration we increase the degree of each term by 1 and divide by the degree.

Thus 35 - 9x becomes [tex]35x - \frac{9x^2}{2} + C[/tex]. We add a constant C for any possible constant that was eliminated during differentiation.

It’s a 50/50 chance since there is only 2 sides. (1?2)

Since PQRS is isosceles, the horizontal distance between PQ and RS is the same, i.e. it's [tex]a[tex].

1. We are given two triangles, ABC and PQR, which are similar to each other.

Given that area of the triangle ABC is [tex]40cm^2[/tex], we are to find the area of the triangle PQR.

For that, we can use the ratio method:

[tex] \frac { P Q R } { 4 0 } = \frac { 6 } { 4 } [/tex]

Answer:

⅖  pizza

Step-by-step explanation:

Divide each pizza into five slices.

Then there will be 10 slices, and each person will get two slices.

Two slices = ⅖ pizza

Each person will receive ⅖ pizza.

Each of the five people will receive 2/5 of a pizza when two pizzas are shared equally amongst them.

The student asked how much pizza each person will receive if five people are sharing two pizzas equally. To answer this, we divide the total number of pizzas by the number of people. Since there are 2 pizzas and each pizza is usually considered to be 1 whole, when split among 5 people, each person will get 2/5 of a pizza.

To determine if the number is a solution to the equation, we have to substitute n with the number given.

56= 8 + 4(6)

56= 8 + 24

56= 32

So no, the number is not a solution to the equation.

The number is a solution of a linear equation if both sides of the equation namely RHS and LHS are equivalent.

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

Given here, the equation as  56 = 8 + 4n  and to verify for n=6

Here, LHS =56 and RHS when n=6 is 8+4×6=32

Thus LHS≠RHS

So the answer is,

The probability that the number is 2,6,3,4, or 1 is 5/6.

Probability is the ratio that shows the likelihood that an event will occur from a given set of events.

A cube has six sides. Each side has a unique number.

We have to find the probability of getting 2,6,3,4, or 1.

The total number of favorable events = 5

The sample space has 6 events.
