Brent bought a reel of thread that is 15.25 metres long. Brent uses 575 centimetres for a project. How much thread in centimetres is left on the reel?
Answer:
There would be 950 cm of thread left on the reel
Step-by-step explanation:
Here in this question, we are interested in knowing the amount of thread left on the reel.
To answer this question properly, we shall need to be consistent in using our units.
Thus, we need to convert the length of thread on the reel to cm.
Mathematically;
100cm = 1 m
let x cm = 15.25 m
x = 15.25 * 100 = 1525 m
Since 575 cm has been used for a project, the amount of thread in cm left on the reel will be;
1525 cm - 575 cm = 950 cm

Factorise x 3 - 2 3 x 2 + 142x - 120????
Answer:
[tex](x - 1)(x - 12)(x - 10)[/tex]
Step-by-step explanation:
Given
Factorize:
[tex]x^3 - 23x^2 + 142x - 120[/tex]
Required
Factorize
We start by checking for the factors of the given polynomial;
Check x - 1 = 0;
This implies that x = 1
Substitute 1 for x in [tex]x^3 - 23x^2 + 142x - 120[/tex]
[tex](1)^3 - 23(1)^2 + 142(1) - 120[/tex]
[tex]= 1 - 23 + 142 - 120[/tex]
[tex]= 0[/tex]
Since the result is 0, then x - 1 = 0 is a factor
Divide the polynomial by x - 1
(See attachment for long division)
The result is: [tex]x^2 - 22x + 120[/tex]
Hence, the factor is
[tex](x - 1)(x^2 - 22x + 120)[/tex]
Expand the quadratic function
[tex](x - 1)(x^2 - 12x - 10x + 120)[/tex]
Factorize
[tex](x - 1)(x(x - 12) - 10(x - 12))[/tex]
[tex](x - 1)(x - 12)(x - 10)[/tex]
Hence;
Factorizing [tex]x^3 - 23x^2 + 142x - 120[/tex] gives [tex](x - 1)(x - 12)(x - 10)[/tex]
A group of friends are playing a board game. As part of the game, each player is given the same number of cards. There are 6 players and 58 cards. How many cards will each player get if each player gets the same number of cards?
Answer: Each player will get 9 cards
Step-by-step explanation:
Given, there are 6 players and 58 cards.
i.e. Total players = 6 and total cards = 58
If each player is given the same number of cards, then by the division operation the number of cards each player will get = ( total cards) ÷ ( total players)
[tex]=58\div6[/tex]
[tex]=9\dfrac{2}{6}[/tex]
Hence, each player will get 9 cards ( 2cards will be left).

A parabola intersects the x-axis at x=3 and x=9.
What is the x-coordinate of the parabola's vertex?
Answer:
6
Step-by-step explanation:
If the graph intersects the x-axis, then there is an x-intercept at that point. So, we know that 3 and 9 are the x-intercepts of the parabola.
Parabolas can only have 0, 1, or 2, x intercepts. The x coordinate of the vertex will be the average of the x coordinates of the x-intercepts, since the vertex will be in the middle of the 2 x intercept points.
Take the average of 3 and 9:
(3 + 9) / 2
12 / 2
= 6
The x coordinate of the vertex is 6.

a rectangle parking lot has an area of 1775 square meters and a perimeter of 192 meters what is it dimension
Answer:
71 & 25 m
Step-by-step explanation:
a • b = 1775
2a + 2b = 192
substitution:
a = 1775/b
2(1775/b) + 2b = 192
distribute the 2
(3550/b) + 2b = 192
subtract 192 from both sides
(3550/b) + 2b - 192 = 0
transform the expression by dividing all terms by b
(3550 + 2b² - 192b) / b = 0
when the quotient of expressions equals 0, the numerator has to be 0
3550 + 2b² - 192b = 0
reorder the terms
2b² - 192 b + 3550 = 0
divide by sides by 2
b² - 96b + 1775 = 0
rewrite -96b as a difference using factoring X
b² - 25b - 71b + 1775 = 0
factor the expression (factor out b)
b (b-25) - 71b + 1775
factor out b - 25 from the expression
(b - 25) (b - 71) = 0
if b = 25 or 71, then a = 71 or 25

Answer:
3) 33 bags
Step-by-step explanation:
she needs 54, but already has 4.5 cubic feet of soil, so really, Maya only needs 49.5 cubic feet of soil.
If each bag contains 1.5 cubic feet of soil, 49.5 feet needed /1.5 feet per bag = 33 bags.

4. In little league baseball, the distance of the paths between each pair of consecutive bases is 60 feet
and the paths form right angles. How far does the ball need to travel if it is thrown from home plate
directly to second base?
Answer:
84.85 feet or 60[tex]\sqrt2[/tex] feet.
Step-by-step explanation:
Given that:
Distance of paths between each pair of consecutive bases is 60 ft.
To find:
Distance that the ball needs to travel if it is thrown directly from home plate to second base?
Solution:
Actually the given problem can be mapped to a right angled triangle in which base and height are given to be equal to 60 ft (because each pair of consecutive bases are 60 ft apart), Plus, they are at right angles to each other.
So, kindly refer to the image attached.
AB and BC are the distance of paths between consecutive bases.
And we have to find AC.
We can use Pythagorean theorem to find out the Hypotenuse of the triangle.
According to Pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow AC^{2} = AB^{2} + BC^{2} \\\Rightarrow AC^{2} = 60^{2} + 60^{2} \\\Rightarrow AC = \sqrt{2 \times 60^2}\\\Rightarrow AC = \bold{60\sqrt{2}\ ft = 84.85\ ft}[/tex]
A horizontal line has points A, B, E, F. A line extends up and to the right from B to point C. A line extends horizontally from point C to point D. A line extends slightly to the left and down from point D to point E. Angle A B C is (3 x) degrees and angle D E F is (2 x) degrees. What is the measure of AngleCBE? 36° 72° 108° 144°
Answer:
The answer is 72 degrees
Step-by-step explanation:
I hope this helps, leave a heart and rating plz!!?:)
The correct option is 72°. The measure of angle CBE is 72° by using the data angle ABC is (3 x) degrees and angle DEF is (2 x) degrees.
To determine the measure of angle CBE, we need to analyze the given information. We are provided with the angles ABC and DEF, where angle ABC is represented by 3x degrees and angle DEF is represented by 2x degrees.
From the description, we can see that angle CBE is formed by the combination of angles ABC and DEF. The angle ABC is adjacent to angle CBE at point B, and the angle DEF is adjacent to angle CBE at point E.
To find the measure of angle CBE, we can use the fact that the sum of the angles in a triangle is always 180 degrees. Since angle ABC and angle D E F are adjacent to angle CBE and form a straight line, they are supplementary angles. Therefore, the sum of angle ABC and angle DEF is 180 degrees.
We can set up the equation:
3x + 2x = 180°
Combining like terms, we get:
5x = 180°
To solve for x, we divide both sides of the equation by 5:
x = 36°
Now that we know the value of x, we can find the measure of angle CBE by substituting x into the expression for angle DEF:
2x = 2 * 36 = 72 degrees
Therefore, the measure of angle CBE is 72 degrees.

Step-by-step explanation:
What is the equation of a line that passes through the point?
=====================================================
Explanation:
The given graph passes through (0,2) and (2,5)
The slope of this line is
m = (y2 - y1)/(x2 - x1)
m = (5-2)/(2-0)
m = 3/2
Since the y intercept is b = 2, we go from y = mx+b to y = (3/2)x+2, which is the equation of the graphed line shown.
Any parallel line will have the same slope, but a different y intercept.
-------------------
The parallel line must pass through (x,y) = (3,2). We'll use these coordinates along with m = 3/2 to find the y intercept b
y = mx+b
2 = (3/2)(3)+b
2 = 9/2+b
2-9/2 = b
4/2 - 9/2 = b
-5/2 = b
b = -5/2 ... is the new y intercept
The equation of the parallel line is y = (3/2)x-5/2, which is in slope intercept form
-------------------
Let's convert to standard form
y = (3/2)x-5/2
2y = 3x-5 .... multiply everything by the LCD 2 to clear out fractions
2y+5 = 3x
3x = 2y+5
3x-2y = 5 ... is the equation in standard form of the parallel line
-------------------
As a check, we can plug (x,y) = (3,2) into that last equation above to get
3x-2y = 5
3*3-2*2 = 5 ... replace x with 3, replace y with 2
9-4 = 5
5 = 5
Confirming that (x,y) = (3,2) is on the line.
