14 - r < 9 ; r = 6 is the given value a solution of the inequality?
Answer:
YESStep-by-step explanation:
14 - r < 9
Put r = 6 and check inequality:
14 - 6 < 9
8 < 9 TRUE
By substituting r = 6 into the inequality 14 - r < 9, we find that the inequality holds true, indicating that r = 6 is a solution to the inequality.
Explanation:To determine if r = 6 is a solution to the inequality 14 - r < 9, we simply substitute the value of r into the inequality and check the result.
Substituting r = 6 into the inequality gives us:
14 - 6 < 9
Which simplifies to:
8 < 9
Since 8 is less than 9, the inequality holds true,
which means that r = 6 is indeed a solution to the inequality 14 - r < 9.

If you know the diameter of a circle, how do you find its circumference?
Group of answer choices
Answer:
circumference of a circle [tex]C = 2\pi r=\pi (d)[/tex]
Step-by-step explanation:
Explanation:-
Circumference of a circle having radius is [tex]C = 2\pi r[/tex]
we know that the radius of circle is 'r'
The diameter of a circle is passing through the center of the given circle.
there fore the diameter of circle is equal to the two times of radius of given circle so d= 2 r
Circumference of a circle having diameter is
[tex]C= 2\pi r = 2r(\pi )[/tex]........(1)
we know that d = 2 r
now the equation (1) is [tex]C= d\pi[/tex]
Therefore The circumference of circle by using diameter is
[tex]C = \pi d[/tex]
Which graph represents a reflection of f(x) = 6(0.5)x across the x-axis?
On a coorindate plane, an exponential function starts in quadrant 3 and increases and approaches y = 0 in quadrant 4. It crosses the y-axis at (0, 6) and goes through (1, negative 3).
On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. It goes through (1, 3) and crosses the y-axis at (0, 6).
On a coordinate plane, an exponential function approaches y = 0 in quadrant 3 and decreases into quadrant 4. It goes through (negative 1, negative 3) and crosses the y-axis at (0, negative 6).
On a coordinate plane, an exponential function decreases from quadrant 2 to quadrant 1 and approaches y = 0 in the first qudrant. It goes through the y-axis at (0, 6) and goes through (1, 3).
The correct graph representing a reflection of the function f(x) = 6(0.5)^x across the x-axis is one that shows the function decreasing into quadrant 4, crosses the y-axis at (0, -6), and approaches y=0 in quadrant 3, precisely matching the expected transformations due to reflection.
Explanation:To find the graph that represents a reflection of f(x) = 6(0.5)^x across the x-axis, it's important to understand what reflection across the x-axis entails. Reflecting a function across the x-axis means taking every point (x, y) on the graph of the function and transforming it into a point (x, -y). Thus, for the function f(x) = 6(0.5)^x, this transformation results in a new function g(x) = -6(0.5)^x. This produces a graph where all y-values are the negatives of the original function's y-values.
Among the provided options, the correct representation of this reflection would be: "On a coordinate plane, an exponential function approaches y = 0 in quadrant 3 and decreases into quadrant 4. It goes through (negative 1, negative 3) and crosses the y-axis at (0, negative 6)." This description matches the characteristics of the reflected function by correctly indicating the new y-intercept at (0, -6) and demonstrating the behavior of the function decreasing into quadrant 4 while approaching y=0 in quadrant 3.

Line XY bisects and is perpendicular to AB and CD. CD = 10 and XY = 24. What is the length of AP?
Answer:
AP = 13
Step-by-step explanation:
See the attached figure.
CD = 10 and XY = 24
Line XY bisects and is perpendicular to AB and CD
∴ XY bisects at Y
∴ CY = 0.5 CD = 0.5 * 10 = 5
And from the geometry of the shape
P is the midpoint of XY
∴ XP = YP = 0.5 XY = 0.5 * 24 = 12
XY is perpendicular to CD
∴ ΔPYC is a right triangle at Y
∴ PC (hypotenuse) = [tex]\sqrt{PY^2+YC^2} =\sqrt{12^2+5^2}=\sqrt{144+25} =\sqrt{169} =13[/tex]
From the figure AP = PC = 13

Randy has 56 pound blocks of ice for his snow cone stand
Tons of ice is 0.028 tons or [tex]\frac{7}{250} \text{ tons }[/tex]
Solution:
Randy has two 28-pound blocks of ice for his snow cone stand
1). How many pounds of ice does randy have at his snow cone stand?
Calculate the total pounds that Randy has
Total pounds = 2 x 28 = 56
Thus Randy has 56 pound blocks of ice for his snow cone stand
2) How many tons of ice is there?
Total pounds of ice = 56 pounds
So we have to convert 56 pounds to tons
Use the conversion factor
1 pound = 0.0005 ton
Therefore, 56 pounds is equal to,
56 pound = 0.0005 x 56 tons = 0.028 tons
Thus in decimal we got, 0.028 tons
Convert to fraction form,
[tex]0.028 = \frac{0.028}{1000} \times 1000 = \frac{28}{1000} = \frac{7}{250}[/tex]
Thus tons of ice is 0.028 tons or [tex]\frac{7}{250} \text{ tons }[/tex]

The left and right page numbers on an
open book add to 333. What are the
page numbers?
and
The student's question is a math problem involving consecutive numbers and a basic linear equation. The page numbers of an open book are consecutive, implying the left page is x and the right is x+1. Solving the equation x+(x+1)=333 results in the left page being 166 and the right page 167.
Explanation:The problem can be approached using the basic concept of consecutive integers in Mathematics. If the total sum of the two page numbers is 333, this means we are dealing with two consecutive numbers (since the left and right page numbers of an open book are always consecutive). Let's represent the left page number as x (unknown at this point). So, the right page number would be x+1 setting up our equation as x+(x+1)=333. Solving this equation will help us find the actual page numbers.
First combine like terms in your equation: 2x+1=333. Subtract 1 from both sides to isolate the term with x: 2x = 332 Divide both sides by 2 to solve for x: x = 166. This is our left page number. Substitute x in to x+1 to find the right page number: x+1 = 167. This is our right page number.
So, the left and right page numbers are 166 and 167 respectively.

One angle of a triangle measures 140°. The other two angles are in a ratio of 3:5. What are the measures of those two angles?
Answer:
15 and 25
Step-by-step explanation:
the interior angles of a triangle, when added, = 180...so if one angle equals 140, then the other 2 angles have to measure a combined total of 40.
the other 2 angles are in a ratio of 3:5....added = 8
so one angle is 3/8 of 40......3/8 * 40 = 120/8 = 15 <===
the other angle is 5/8 of 40....5/8 * 40 = 200/8 = 25 <==
Final answer:
To find the measures of the other two angles in the triangle, set up a ratio between them: angle 1 is 3x and angle 2 is 5x. Solve the equation and find that the measures of angle 1 and angle 2 are 15° and 25°, respectively.
Explanation:
To find the measures of the other two angles in the triangle, we can set up a ratio between them. Let's call one angle 3x and the other angle 5x. We know that the sum of all three angles in a triangle is 180°. So we can write the equation: 140° + 3x + 5x = 180°.
Simplify the equation: 140° + 8x = 180°.
Subtract 140° from both sides: 8x = 40°.
Divide both sides by 8: x = 5°.
Now we can find the measures of the other two angles: Angle 1 = 3x = 3(5°) = 15°. Angle 2 = 5x = 5(5°) = 25°.

First we need to factor all the polynomials here using quadratic equation (-b +/- √(b^2 - 4ac)) / 2a :
* 2y^2 - 6y - 20 = 2(y^2 -3y - 10)
From quadratic equation, solutions are 5 and -2, which means that we can factor this to;
2(y+2)(y-5)
* y^2 + 5y + 6, in the same manner, is found to have solutions -3 and -2, so it can be factored to:
(y+3)(y+2)
* 3y^2 + 18y + 27 = 3(y^2 + 6y + 9)
Again, solving quadratic equation, we find solution to be -3, so we factor this to:
3(y+3)(y+3)
* 4y + 12 equals to 4(y+3)
Now, let's rewrite our polynomials:
2(y+2)(y-5) • 3(y+3)(y+3) / 4(y+3) • (y+3)(y+2)
We see that we can cancel out some factors here (x+3) and (x+2), so we are left with 6(y-5) / 4 which is 3(y-5)/2.

Are 8÷2 and 2÷8 equivalent
Answer:
No, 8 / 2 and 2 / 8 are not equivalent.
Step-by-step explanation:
2 Numbers switched makes a different result.
For example, switching numbers in 82.
As we switch the 8 and the 2, we get 28.
28 is not equivalent to 82.
As we do 8 / 2, when we switch the numbers, we get 2 / 8.
2 / 8 is not equivalent to 8 / 2.
As we solve both equations, 8 / 2 = 4, 2 / 8 = 0.25.
0.25 is not equivalent to 4.
Therefore, 8 / 2 and 2 / 8 are not equivalent.
