Answer:

Mass on mars is 150 grams.

Step-by-step explanation:

We have, mass of a book is 150 grams on the surface of Earth. The amount of matter contained in it is called its mass.

Mass of an object remains constant always. Its value is same in every location.

If the mass of a book on the surface of Earth is 150 grams, then its mass on Mars is also 150 grams. This is because, mass of an object is independent of its location.

Final answer:

The inequality to determine the minimum amount each cheerleader needs to raise to cover the team fee and individual entry fees is m >= $50.99. This is calculated by dividing the team fee of $99 and the total individual fees of $818.82 by 18 cheerleaders, and summing those amounts.

Explanation:

The question asks to find an inequality to determine the minimum amount of money, m, each cheerleader needs to raise to cover both the team fee and individual fees. Coach Walker's cheerleading team has a total team fee of $99 and individual fees amounting to $818.82 for 18 cheerleaders.

To find the equation that expresses the total cost, we start with the total individual fee for the cheerleaders, which is $818.82. This fee needs to be divided among the 18 cheerleaders, and when added to the team fee that is split equally, it gives the amount each cheerleader should raise.

The inequality should ensure that the total amount raised by each cheerleader, m, is enough to cover both their share of the team fee and their individual fee. The equation for the team fee per cheerleader is $99 divided by 18. We can add the individual fee of $818.82 divided by 18 to this amount to find the minimum amount each cheerleader should raise.

Setting up the Inequality

First, calculate the per person cost for the team fee: $99 / 18 = $5.50 per cheerleader.

Second, calculate the per person individual fee cost: $818.82 / 18 = $45.49 per cheerleader.

Now, we add both of these to find the total minimum amount each cheerleader should raise: $5.50 (team fee per cheerleader) + $45.49 (individual fee per cheerleader) = $50.99.

The inequality that represents the minimum amount each cheerleader needs to raise is:

m >= $50.99

This inequality ensures that each cheerleader raises at least enough to cover their portion of the fees.

Answer:

a. 1.5 kg of tuna, 1 kg of onion, 0.75 kg of red pepper and 2.4 kg of tomatoes

b. 16 empanadas

Step-by-step explanation:

Since each of these ingredients is needed and the recipe is for a single empanada, each ingredient in the recipe must be multiplied by 6 since they are 6 empanadas, like this:

1/4 kg tuna * 6 = 6/4 = 3/2 kg tuna

1/6 kg of onion * 6 = 6/6 = 1 kg of onion

1/8 kg of red pepper * 6 = 6/8 = 3/4 kg of red pepper

2/5 kg of tomatoes * 6 = 12/5 kg of tomatoes

Therefore 1.5 kg of tuna, 1 kg of onion, 0.75 kg of red pepper and 2.4 kg of tomatoes need it.

Now, with 2 kg of red pepper, what we should do is divide this quantity by the quantity for a recipe, like this:

2 / (1/8) = 16

that is to say that with 2 kg of red pepper, a total of 16 empanadas would be made

Answer:

The length of the wire in millimeters is 9 × 10² mm.

Step-by-step explanation:

1 meter is equal to 1000 millimeters. This is the ratio that we use to convert a length in meters to one in millimeters.

0.9 m × (1000 mm/ 1 m) = 900 mm = 9 × 10² mm (we round off to 1 significant figure)

As per the given table of values, we have identified that the function that is most likely increasing quadratically is f(x).

Let's examine the given values in the table:

x f(x) g(x)

1 3 3

2 6 9

3 9 27

4 12 81

5 15 243

For a quadratic function, the differences between consecutive values of f(x) should increase by a constant amount. Let's calculate the differences between consecutive f(x) values:

x f(x) Difference (∆f(x))

1 3

2 6 6 - 3 = 3

3 9 9 - 6 = 3

4 12 12 - 9 = 3

5 15 15 - 12 = 3

The differences (∆f(x)) between consecutive f(x) values are constant and equal to 3. This indicates that the function f(x) is increasing quadratically.

Now, let's examine the differences between consecutive g(x) values:

x g(x) Difference (∆g(x))

1 3

2 9 9 - 3 = 6

3 27 27 - 9 = 18

4 81 81 - 27 = 54

5 243 243 - 81 = 162

The differences (∆g(x)) between consecutive g(x) values are not constant; they are increasing exponentially. This suggests that the function g(x) is increasing exponentially.

Step-by-step explanation: 7.874007874011811 rounded is 8

Answer:

Step-by-step explanation:

If you don't want to use a calculator, then you must know your square roots

The first step is to think, "what is the closest number to 62, that when squared rooted, it would be a whole number?"

The closest numbers would be 49 (square root is 7)and 64 (square root is 8). But 64 is wayyy closer so by knowing the square root, you can work your way down to solve.

So you know that the square will inevitably be a decimal, and that the whole number will have to be 7 ( it can't be 8 because then it'll be higher than 64) and the decimal would have to be really high, like in between 5 and 9 bc 62 and 64 are really close.

Now this is just an estimate is it doesn't have to be exact. but I'm guessing the root would be around 7.8ish (rounded to nearest tenth)

but you can have a different answer, maybe closer :)

Answer:

3.64

Step-by-step explanation:

Based on the calculations, the radius of Circletown is equal to 3.64 kilometer.

Given the following data:

First of all, we would determine the area of Circletown by dividing the total population by its population density as follows:

Area = 20,000/480

Area = 41.67 square kilometer.

Mathematically, the area of a circle is calculated by using this formula:

Area = πr²

Where:

r is the radius of a circle.

Substituting the given parameters into the formula, we have;

41.67 = 3.142 × r²

r² = 41.67/3.142

r = √13.26

r = 3.64 kilometer.

62/2=31  100/2=50

Answer:

31/50

Step-by-step explanation:

We have been given an image of a trapezoid. We are asked to find the area of the given trapezoid.

We will use area of trapezoid formula to solve our given problem.

[tex]A=\frac{1}{2}(a+b)\times h[/tex], where,

A = Area of trapezoid,

a and b = Parallel sides or bases of trapezoid.

h = Height of trapezoid.

We can see that one base is 45 feet. The other base would be 45 plus 15 feet that is [tex]45+15=60[/tex].

Now we will use Pythagoras theorem to find the height of the trapezoid as:

[tex]h^2=17^2-15^2[/tex]

[tex]h^2=289-225[/tex]

[tex]h^2=64[/tex]

[tex]\sqrt{h^2}=\sqrt{64}[/tex]

[tex]h=8[/tex]

[tex]A=\frac{1}{2}(45+60)\times 8[/tex]

[tex]A=(105)\times 4[/tex]

[tex]A=420[/tex]

Therefore, the area of the given trapezoid is 420 square feet.

Answer:

5 right triangle

6 not a right triangle

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = 13^2

25+144 = 169

160 = 169

This is true so this is a right triangle

15^2 +16^2 = 18^2

225 +256 = 324

481 does not equal 324

This is not a right triangle

Answer:

5. Yes

6. No

Step-by-step explanation:

5. 13² = 12² + 5²

169 = 144 + 25

169 = 169

Satisfies pythagoras theorem, so it is a right angle triangle

6. 18² = 16² + 15²

324 = 256 + 225

324 = 481 (false)

Doesn't satisfy the pythagoras theorem, so it is not a right angle triangle

Answer:

We divided the figure into 1 triangle and 2 rectangles.

Adding up the area of them, we get the total area:

A = area of triangle + area of 2 rectangles

   =  base x height/2 + length1 x width1 + length2 x width2

   = 7 x (15 + 2 - 6 - 2)/2 + 8 x 15 + 5 x 2

   = 161.5

Answer: 14

Step-by-step explanation: To get the hypotenus of a triangle all you have to do is:

7 x 7 = 14

1 x 1 = 1

14 x 1 = 14

14 x 14 = 196

square root of 196 is 14

Equation form:

a² + b² = c²

7² + 1² = 14²

Sqrt(196) = 14

Answer:

0.027 to the nearest thousandth.

Step-by-step explanation:

There are 14 marbles in the bag, so:

Prob( a blue on the first draw) = 5/14.

Prob( a blue on the 2nd draw) = 4/13.

Prob( a blue on the 3rd draw) = 3/12 = 1/4.

So the required probability is 5/14 * 4/13 * 1/4

= 20/ 728

= 0.02747.

To calculate the probability of drawing three blue marbles without replacement, multiply the probabilities of drawing a blue marble in each draw. The final probability to the nearest thousandth is approximately 0.043.

To find the probability that all three marbles drawn will be blue, we use the formula for calculating the probability of successive independent events (drawing without replacement). We calculate the probability of drawing a blue marble each time and then multiply these probabilities together.

Calculating this, we get approximately 0.043 when rounded to the nearest thousandth. So, the probability that all three marbles drawn will be blue is 0.043.

Answer:

A cross-section parallel to the base is a rectangle measuring 15 inches by 8 inches.

A cross-section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.

A cross-section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.

Step-by-step explanation:

the cross sections that are parallel and perpendicular will have the same measurements as the non-intersected sides. the last one will be a diagonal so the intersected edge is 6 and it creates a right triangle so it must be larger than 15 inches.

Answer:

6 days

210 pages

Step-by-step explanation:

As stipulated by the question, let the number of days Amir has been reading be x and the number of pages he had read to be y.

Now since he reads 35 pages per day.

Then mathematically;

y = 35x

For Jesse, He started reading a day before, this means that the number of days he had read would be x + 1. Since he reads 30 per day, the total number of pages he would have read is 30(x+1)

To find the number of days which is x, we have to assume that at a point in time, the number of books they would have read would be the same meaning that

Also; y = 30(x + 1)

Equating the two situations

35x = 30(x + 1)

35x = 30x + 30

35x -30x = 30

5x = 30

x = 30/5

x = 6 days

This means that it will take Amir 6 days to catch Jese.

The number of books they would have read by then is y = 35x = 30(x + 1)

= 35 * 6 or 30(6+1)

= 210

The total number of pages that he read will be 210 pages.

Based on the equation given, the equation to represent Amir's information will be:

y = 35 × x

y = 35x

Jesse's equation will be:

y = 30(x + 1)

Then, we'll equate both equations together. This will be:

35x = 30(x + 1)

35x = 30x + 30

35x - 30x = 30

5x = 30

x = 30/5

x = 6

Therefore, the number of pages read will be:

y = 35x

y = 35 × 6

y = 210 pages.

Answer:

5.1 is rational because it can be expressed in the form of a fraction.  In proper form the fraction is 5 1/10 and in improper form it is 51/10.

Step-by-step explanation:

For u = (-6,8) and v = (7,1), the vector u can be written as the sum of two orthogonal vectors (-4.76, -0.68) and (-1.24, 8.68) where one is the projection of u onto v.

First, we need to find the vector projection of u onto v. The formula to find the vector projection of u onto v is given by: projv(u) = [(u.v)/(v.v)] * v. Here '.' represents dot product of vectors.

So, substitute the given vectors u = (-6,8) and v = (7,1) into the formula.

This is one of the vectors. The other vector, orthogonal to v, is given by u minus the projection: u - projv(u) = (-6,8) - (-4.76, -0.68) = (-1.24, 8.68).

So, the vector u can be written as the sum of two orthogonal vectors (-4.76, -0.68) and (-1.24, 8.68).
