Final answer:

To find the number of games won and lost by the baseball team, use the given win to loss ratio of 4/3 and the total number of games played (147) to establish a system of equations and solve for the number of wins and losses. The team won 84 games and lost 63 games.

Explanation:

The student has asked how many games a baseball team won and lost given that they played 147 regular season games with a win to loss ratio of 4/3. To solve this, let w represent the number of games won and l represent the number of games lost. According to the ratio, we have w/l = 4/3. Because the total number of games is 147, we can express this as w + l = 147.

First, express the number of losses in terms of wins using the ratio: l = 3w/4.

Next, substitute l in the total games equation: w + 3w/4 = 147.

Solving for w gives w = 84 (number of games won).

To find l, substitute w back into l = 3w/4 to get l = 63 (number of games lost).

The baseball team won 84 games and lost 63 games.

The area of circle of circumference 37.7 is 112.76 .

The area of a circle is pi times the radius squared (A = π r²)

where ,

A = Area of circle

r = radius of circle

The circumference of a circle is defined as the linear distance around it.

C=2πr

where ,

c = circumference of circle

r = radius of circle

According to question

Circumference = 37.7

2[tex]\pi r\\[/tex] = 37.7

[tex]\pi r[/tex] = 18.85

[tex]\frac{22}{7}r[/tex]=18.85   ([tex]\pi = 22/7[/tex])

The explicit rule for the given geometric sequence is [tex]a(n) = 120 \times (1/3)^{n-1}[/tex].

A geometric sequence is a sequence in which each term after the first is found by multiplying the previous term by a constant called the common ratio.

For the given sequence: 120, 40, 40/3, 40/9, 40/27, ... let's determine the explicit rule.

Identify the first term, a:

The first term is 120.

Determine the common ratio, r:

The ratio of any term to the previous term is 40 / 120, which simplifies to 1/3.

Write the explicit rule:

The nth term of a geometric sequence is given by the formula:

[tex]a(n) = a \times r^{n-1}[/tex]

IQR

Step-by-step explanation:

Interquartile range (IQR): it's the difference between the largest and smallest values in the middle 50% of a set of data. It is not affected by the long tail in the graph because its calculation only consider the central part of data.

Range: it’s the difference between the highest value and the lowest value in a data set. It is affected by long tails because consider the whole data

Median absolute deviation (MAD): it's the median of the absolute deviations from the data's median. It's moderate affected by long tails because atypical measures give greater absolute deviation that may cause a greater MAD.

For the given condition of lines to be parallel, slope of red line is same as green line which is equal to [tex]\frac{-3}{7}[/tex].

" Parallel lines are defined as the lines in the same plane with equal distance between them and do not intersect in the same plane."

" Slope is defined as the ratio of increment in the y-coordinates to the x-coordinates."

Condition of slope for two parallel lines

[tex]y = m_{1} x + c_{1}\\\\y = m_{2} x + c_{2}[/tex]

[tex]m_{1}[/tex] and [tex]m_{2}[/tex] represents the slope of parallel lines.

As slope of parallel lines always equal.

Therefore,

[tex]m_{1} = m_{2}[/tex]

According to the question,

Given,

The slope of the green line [tex]= \frac{-3}{7}[/tex]

Condition given,

Lines are parallel.

Using the condition of slope of parallel lines we have,

The slope of the parallel lines is always equal.

Therefore,

The slope of the red line [tex]= \frac{-3}{7}[/tex]

Hence, the slope of the red line [tex]= \frac{-3}{7}[/tex] as per the given lines is parallel.

[tex]\large\boxed{x=4\pm2\sqrt6}[/tex]

Step-by-step explanation:

[tex]x^2-6x+12=2x+20\qquad\text{subtract}\ 2x\ \text{and}\ 12\ \text{from both sides}\\\\x^2-8x=8\\\\x^2-2(x)(4)=8\qquad\text{add}\ 4^2=16\ \text{to both sides}\\\\x^2-2(x)(4)+4^2=8+4^2\qquad\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\(x-4)^2=24\iff x-4=\pm\sqrt{24}\\\\x-4=\pm\sqrt{4\cdot6}\\\\x-4=\pm\sqrt4\cdot\sqrt6\\\\x-4=\pm2\sqrt6\qquad\text{add 4 to both sides}\\\\x=4\pm2\sqrt6[/tex]

Final answer:

The quadratic equation x² - 6x + 12 = 2x + 20 is solved by completing the square, resulting in the solution x = 4 ± √24.

Explanation:

To solve the quadratic equation x² - 6x + 12 = 2x + 20 by completing the square, we first need to rearrange the equation to get 0 on one side. We do this by subtracting 2x and 20 from both sides, which gives us:

x² - 8x - 8 = 0

Next, we find the value to complete the square for the x terms. We take half of the coefficient of x, which is 8/2 = 4, and then square it, getting 4² = 16. We add 16 to both sides of the equation to form a perfect square on the left:

x² - 8x + 16 = 8 + 16

This simplifies to:

(x - 4)² = 24

To find the value of x, we take the square root of both sides:

x - 4 = ±√24

Finally, we solve for x:

x = 4 ± √24

The volume of the right rectangular prism with dimensions of 7 cm by 5 cm by 4 cm is 140 cubic centimeters (140 cm³).

To calculate the volume of a right rectangular prism, you can use the formula: Volume (V) = length (l) × width (w) × height (h). For a prism with a length of 7 centimeters, a width of 5 centimeters, and a height of 4 centimeters, the volume is calculated as follows:

V = 7 cm × 5 cm × 4 cm
V = 35 cm × 4 cm
V = 140 cm³

So, the volume of the prism is 140 cubic centimeters (140 cm³).

Answer:

The polynomial result sum is [tex]2x^{2} +4x+6[/tex]

Step-by-step explanation:

To calculate the sum of the polynomial expressions first we have to write individually each one and sum the terms of it:

Fisrt one: [tex]x^{2} + x + x+ 1 + 1 = x^{2} +2x+2[/tex]

Second one: [tex]x^{2} +x+x+1+1+1+1=x^{2} +2x+4[/tex]

Now having both equations in simplified form we can sum them:

[tex]x^{2} +2x+2+x^{2} +2x+4=2x^{2} +4x+6[/tex]

So the sum of the polynomial equations is: [tex]2x^{2} +4x+6[/tex]

Answer:

5 boxes

Step-by-step explanation:

Given that;

The total amount Ray has with him to buy masonary nails and finishing nails for his project is $36

If Masonry nails sell for $5.50 per box

Finishing nails cost $3.50 per box.

Now, Only full boxes are available for purchase.

If Ray buys 3 boxes of masonry nails

i.e 3 × $5.50 = $16.5

what is the maximum number of boxes of finishing boxes he can buy?

To determine the number of finishing nails boxes he can buy. we will subtract the expense spent on the prior 3 masonary nails from his total amount

i.e $36 - $16.5

= $19.5

Let's not forget that, only full boxes are available for purchase and not half or quarter.

SO since 1 finishing nail box cost $3.50

then let x finishing nail box cost $19.5

∴ (x) × $3.50 =1 × $19.5

(x) = [tex]\frac{1*19.5}{3.50}[/tex]

(x)  = 5.57 boxes

Since full boxes are available for purchase then   (x)  ≅ 5 boxes, then Ray will be left with $2 at his pocket.

Therefore, the maximum number of boxes of finishing boxes he can buy is 5 boxes

Step-by-step explanation:

Let's use this equation as an example - [tex]102=-7r+4[/tex]

The whole point of a linear equation is to find what the variable (which in our case is r ) equals to.

Our equation: [tex]102=-7r+4[/tex]

First step is to try to get r alone on one side.

First step: [tex]102-4=-7r[/tex] we wouldn't do [tex]102+4=-7r[/tex] (notice it's negative and not positive) since we're switching the positive 4 to the other side we'd switch the positive to a negative, making it [tex]102-4[/tex].

Know that everytime we switch a number or variable to the other side we must always switch the sign to the opposite of what it is. If it's dividing, we multiply, if we subtract, we add, etc. Same with the other way around.

Second step is to solve both sides of the equation.

Second step: [tex]98=-7r[/tex]

Third step is to divide the both sides by the number with the variable, making it 98 divided by -7r and -7r divided by -7

Third Step: [tex]\frac{98}{-7} =\frac{-7r}{-7}[/tex] = [tex]-14=r[/tex]

Now we've found our variable.

Answer: [tex]-14=r[/tex]

The supplement of an angle that measures 20 degrees will be 160°. Then the correct option is D.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The one angle is 20 degrees. Then the other angle is given as,

x + 20° = 180°

x = 180° - 20°

x = 160°

The supplement of an angle that measures 20 degrees will be 160°. Then the correct option is D.
