The mass of Earth’s Moon is about 7 X 10 to the 22 power kilograms. The Mass of Jupiter is about 1.89 x 10 to the 27 Power Kilograms. how many times the mass of Earth’s Moon?

Answer:

first = 21 - 5 = 16

second  = 21

Third = 21*2 = 42

Step-by-step explanation:

first + second + third = 79

Let the second number = x

third = 2*x

first = x - 5

So we get

x - 5 + x + 2x = 79

4x - 5 = 79                  Add 5

4x - 5 + 5 = 79 + 5     Combine

4x= 84                         Divide by 4

4x/4 = 84/4

x = 21

Final answer:

Using algebraic methods, the three numbers are determined to be 16, 21, and 42. The values are obtained by setting up an equation based on the given relationships and solving for the variable.

Explanation:

We are tasked with determining the values of three numbers where the sum is 79, the third number is twice the second, and the first number is 5 less than the second. Let's define the second number as x. Therefore, the third number would be 2x and the first number would be x - 5. Setting up the equation based on these relationships, we have:

(x - 5) + x + (2x) = 79

Combining like terms, we get:

4x - 5 = 79

Adding 5 to both sides to isolate the variable, we find:

4x = 84

Dividing by 4 gives us:

x = 21

Now we can find the first and third numbers:

First number: x - 5 = 21 - 5 = 16

Second number: x = 21

Third number: 2x = 2(21) = 42

The numbers are 16, 21, and 42.

Answer:

AB=15 BC=60

Step by step:

AB+BC=AC

AC=75

Plug in AC to the equation: AB+BC=75

BC=4(ab)

Plug in BC into the equation: AB+4(AB)=75

Simplify: 5AB=75

Divide each side by 5: AB=15

BC=4(15)=60

Answer:  AB = 60, BC = 15

Step-by-step explanation:

AB is 4 times bigger than BC ⇒    AB = 4BC

Use the Segment Addition Property: AB + BC = AC

and substitution (replace AB with 4BC) and (AC with 75) to solve for BC

4BC + BC = 75

        5BC = 75

          BC = 15

AB = 4BC

    = 4(15)

    = 60

Answer:

0.9

Step-by-step explanation:

The best way to estimate the value of correlation coefficient from scatter plot is draw a straight line such that the distance between the straight line and scatter point is minimum.

If the direction of straight line is towards top right then value of correlation coefficient is positive otherwise if direction of straight line is towards bottom right then value of correlation coefficient is negative.

And, if straight line is nearly horizontal then value of correlation coefficient is nearly 0.5 or -0.5.

Thus, we have only two possible values of correlation coefficient which is 1 or 0.9

Also, here we see that as the value of x is increasing the value of y is also increasing but it is comparatively less than the increase of x.(See the scatter points (3, 2), (8, 6) and (2.1, 1.9)). If both rate of change is constant then value of correlation coefficient is 1.

Hence, value of correlation coefficient is 0.9

Answer:

5/3 hours

Step-by-step explanation:

2/3 hour = 40 minutes

You can solve it by proportion:

40 minutes = 2/5 room

x minutes = 1 room

[tex]x=\frac{40}{\frac{2}{5} }[/tex]

100 minutes = 5/3 hours

Answer: 1 hour 40 minute

Step-by-step explanation:

If it take 2/3 of an hour to paint 2/5 of a room

1Hour = 60min

2/3 of 60min

2/3 × 60min

=120min / 3

= 40min

That is it take 40min to paint 2/5 of a room

So using proportion

2/5 room = 40min

1room = X min

We cross multiply

2/5 × X = 40min

2X / 5 = 40min

We cross multiply again

2X = 200min

Divide bothside by 2

x = 100 min

But 1hour =60min

Therefore 100min = 1 hour 40min.

Answer: 257

Step-by-step explanation:

|-143 + 400| = 257

The hiker starts 143 feet below sea level (-143). After climbing 400 feet, the hiker is now 257 feet above sea level.

The hiker's initial elevation is 143 feet below sea level, which we represent as -143. The hiker then climbs 400 feet, so we add this to the initial elevation. Therefore, the calculation is: -143 + 400 = 257.

This means that the hiker's new elevation, relative to sea level, is 257 feet above sea level.

Answer:

The perimeter of the rectangle is 17.70 feet

Step-by-step explanation:

- The perimeter of a rectangle is → P = 2l + 2w → where l is its length

  and w is its width

- A rectangle has a length 15x and a width 2x³ + 4 - 2x²

- We need to find its perimeter when its length is 5 feet

∵ The length of the rectangle is 15x

∵ The length of the rectangle is 5 feet

- Equate the length's expressions

∴ 15x = 5

- Divide both sides by 15

∴ [tex]x=\frac{1}{3}[/tex]

- Now lets find the width of the rectangle

∵ The width of the rectangle = 2x³ + 4 - 2x²

∵ [tex]x=\frac{1}{3}[/tex]

- Substitute the value of x in the expression of the width

∴ [tex]w=2(\frac{1}{3})^{3}+4-2(\frac{1}{3})^{2}[/tex]

∴ [tex]w=2(\frac{1}{27})+4-2(\frac{1}{9})[/tex]

∴ [tex]w=\frac{2}{27}+4-\frac{2}{9})[/tex]

∴ [tex]w=\frac{104}{27}[/tex] feet

Answer:

Step-by-step explanation:

The measure of an angle being equal to itself is an example of the Reflexive Property, which states that any quantity is equal to itself.

The statement "The measure of an angle is equal to itself" is true because of the Reflexive Property. This property states that any quantity is equal to itself, which is a fundamental idea in mathematics and logic. In the context of geometry and angles, it means that an angle is always equal to its measure. So, if θ represents the measure of an angle, then we could say θ = θ, which demonstrates the Reflexive Property.

The other properties listed—the Property of Equality, Symmetric, and Transitive—are also important in the realms of algebra and geometry but do not directly apply to the fact that an entity is equal to itself. Instead, these properties involve the relationship between different entities or the equality between them derived from other equalities.

Final answer:

To find the side length of the original square, we formed a quadratic equation based on the given information and solved it to get a side length of 5 meters.

Explanation:

The question asks us to find the length of a side of the original square when the sides are increased by 3 meters and the new area becomes 64 square meters. First, let's denote the side length of the original square as x. If each side of the square is increased by 3 meters, then the new side length is x + 3 meters. The area of the new square is given to be 64 m², which can be represented as the square of the new side length, so the equation becomes:

(x + 3)²= 64

This simplifies to:

x² + 6x + 9 = 64

Subtracting 64 from both sides:

x² + 6x - 55 = 0

This is a quadratic equation that we can solve by factoring or using the quadratic formula. In this case, the equation factors to:

(x + 11)(x - 5) = 0

This gives us two possible solutions for x: -11 or 5. Since a side length cannot be negative, we disregard the -11 and conclude that the side length of the original square is 5 meters.

Answer:

a) Value T's and More

b) y = 8x

c) 8; cost per t-shirt

d) $25

e) Value T's and More for orders of fewer than 25 t-shirts.
    Print-o-Rama for larger orders of more than 25 t-shirts.

Step-by-step explanation:

We are given that Allison’s middle school team has designed t-shirts featuring their team name and color. Allison and her friend Nicole have volunteered to call local stores to get an estimate of the total cost of purchasing the t-shirts.

[tex]\dotfill[/tex]

A proportional relationship is a linear relationship between two variables where the ratio of one variable to the other is constant, and the graph of this relationship passes through the origin (0, 0).

Value T's and More represents a proportional relationship because the cost per t-shirt is constant at $8, and the graph modelling the data for this company passes through the origin (0, 0), meaning that when no t-shirts are purchased, the cost is $0.

Print-o-Rama does not represent a proportional relationship because although they charge a fixed amount per t-shirt, there is an additional set-up fee. This makes the cost function in the form y = mx + b (where b is the set-up fee), resulting in a graph that does not pass through the origin (0, 0).

[tex]\dotfill[/tex]

A proportional relationship can be expressed as y = kx, where k is the constant of proportionality.

Since the cost per t-shirt at Value T's and More is constant at $8, the constant of proportionally is k = 8, so the equation relating cost (y) and shirts (x) for Value T's and More is y = 8x.

[tex]\dotfill[/tex]

As discussed in part b, the constant of proportionality for ValueT's and More is 8. This represents the cost per t-shirt (in dollars).

[tex]\dotfill[/tex]

To find the set-up fee, let's use the given points (10, 95) and (50, 375) for Print-o-Rama and assume the cost model is y = mx + b, where m is the cost per shirt, and b is the set-up fee.

Substitute both points into y = mx + b to set up two equations:

[tex]95=10m + b\\\\375=50m+b[/tex]

Subtract the first equation from the second equation to eliminate b, then solve for m:

[tex]375-95=(50m+b)-(10m+b) \\\\280=40m\\\\m=7[/tex]

This means that the cost per t-shirt is $7.

Substitute m = 7 back into one of the equations and solve for b. Let's use 95 = 10m + b:

[tex]95 = 10(7) + b \\\\95=70+b\\\\b=95-70\\\\b=25[/tex]

Therefore, the set-up fee for Print-o-Rama is $25.

[tex]\dotfill[/tex]

To determine the most cost-effective supplier, we need to equate the cost equations of Value T's and More and Print-o-Rama to identify the exact number of t-shirts at which the costs for both companies are equal:

[tex]8x=7x+25\\\\8x-7x=25\\\\x=25[/tex]

Solving 8x = 7x + 25 for x gives us x = 25, meaning that for an order of 25 t-shirts, the total cost from both suppliers is the same. For orders of fewer than 25 t-shirts, Value T's and More is cheaper, but for orders of more than 25 t-shirts, Print-o-Rama is more cost-effective due to its lower per-shirt cost despite the set-up fee.

Therefore, after analysing the pricing models of both Value T’s and More and Print-o-Rama, it is recommended to use:

a. The graph shows a proportional relationship

b. The proportional equation is  y = 8k

c. The constant of proportionality is 8

d. Print-o-Rama's set up fee is 25

a. A linear graph that intercepts the origin has a proportional relationship.

b. The equation is written in the form y = kx, using point (10, 80)

80 = 10k

k = 8

The equation is written as y = 8k

c. The constant of proportionality is k which is equal to 8

d. The set up fee is the y-intercept (b). The equation is written in the form y = mx + b

m = (375 - 95) / (50 - 10)

m = 280 / 40

m = 7

Using point slope formula

y - 95 = 7 (x - 10)

y = 7x - 70 + 95

y = 7x + 25

The y-intercept, b is 25

The function g(x) = f(-x) represents a reflection of the graph of f(x) across the y-axis. This transformation swaps the values of the function for positive and negative x values, creating a mirror image.  So since the max of f was when x = 2, the max of g will be when x = -2.

Understanding the Transformation of Function g(x) = f(-x)

function g(x) = f(-x).

This indicates a transformation where the function f(x) is reflected across the y-axis.

To put it simply, the graph of y = f(-x) is the mirror image of the graph of y = f(x) across the y-axis.

f g(x) = f(-x), the graph of g looks like a mirror image of f, where the y-axis is the mirror.  

For example, g(1) will be what f's value at -1 was (-1).  g(2) = f(-2) = -3.  g(3) = f(-3) = -1.  etc.  

So since the max of f was when x = 2, the max of g will be when x = -2.

Here’s an example to illustrate:

Suppose f(x) = x².

The graph of y = f(x) is a parabola facing upwards.

For y = f(-x), or y = (-x)²,

the graph will still be a parabola facing upwards.

Since g(x) = f(-x), the absolute values are not changed but the sign change in x reflects each point across the y-axis.

This reflection happens because negating the independent variable x means we swap the values of the function at positive and negative x values.
