Answer:
24 Home games
Step-by-step explanation:
let [tex]x[/tex] denote the number of home games played, and [tex]y[/tex] denote the number of home games played. We are given the total number of games played as 49
and total wins as 26.
The problem can be expressed in equation form as:[tex]\frac{2}{3}x+\frac{2}{5}y=26[/tex]...[tex]eqtn1[/tex]
Total games is expressed as [tex]x+y=49[/tex]...[tex]eqtn2[/tex]
Rewrite equation 1 to remove fractions:
[tex]\frac{2}{3}x+\frac{2}{5}y=26\\=>5x+3y=195\\[/tex]
Solve for x to obtain total home games played.
Making [tex]x[/tex] the subject in eqtn 2:
[tex]x=49-y[/tex]
Substitute for [tex]x[/tex] in eqtn1:
=>
[tex]5(49-y)+3y=195\\-5y+3y=195-245\\-2y=-50\\y=25[/tex]
To obtain [tex]x[/tex], replace y value in eqtn2:
[tex]x+y=49\\y=25\\Therefore\\x=49-25\\x=24[/tex]
Home games played is 24

volume of a cone with a diameter of 3.5 and a height of 8.4.
Answer: volume is 26.9
Step-by-step explanation:
Volume of a cone is calculated by V=πr^2h/3
Where π is a constant, with value of 3.14
h is height, given as 8.4
r is radius, radius = diameter ÷ 2
Since Diameter is given as 3.5, radius = 3.5/2 = 1.75
Slot the values into the formula
V= 3.14 x 1.75^2 × 8.4/3
= 3.14 x 3.06 x 2.8
=26.9

A solution to the equation x^3 −10x=100 using the trial and improvement method is approximately x=5.3 (rounded to 1 decimal place).
let's use the trial and improvement method to find a solution for the equation
x^3 −10x=100.
Start with a reasonable guess for x. In this case, it's often helpful to start with small integers.
Substitute the guess into the equation and see if it satisfies the equation.
Let's try
5^3 −10×5=125−50=75
The result is not equal to 100. Since the result is less than 100, we need to increase our guess.
Let's try
6^3 −10×6=216−60=156
The result is still not equal to 100. Since the result is now greater than 100, we need to decrease our guess.
Let's try
5.5^3 −10×5.5=166.375−55=111.375
This result is still greater than 100, so we need to try a smaller value.
5.2^3 −10×5.2=140.608−52=88.608
Now, this result is closer to 100. We can continue to refine our guess.
Let's try
5.3^3 −10×5.3=150.097−53=97.097
This result is getting closer to 100. We can keep refining our guess, but for the sake of brevity, let's stop here.
So, a solution to the equation x^3 −10x=100 using the trial and improvement method is approximately x=5.3 (rounded to 1 decimal place).

Which statements are true about the components of a circle? Check all that apply.
The radius is half the length of the diameter.
The circumferences is triple the radius.
The circumference is the perimeter of a circle.
To find the circumference, multiply it by the diameter.
The diameter is triple the length of the radius.
The radius of a circle is half the length of the diameter, and the circumference is the perimeter of the circle. However, the circumference is not triple the radius, and the diameter is not triple the length of the radius.
Explanation:In the context of Mathematics, particularly geometry, the following statements are indeed true about the components of a circle:
The radius is half the length of the diameter. This is because the radius of a circle is defined as the distance from the center of the circle to its edge, while the diameter is the distance across the circle passing through the center. The circumference is the perimeter of the circle. This perimeter is also called the circumference in the context of circles, as it is the length around the edge of the circle.However, the statements that the circumference is triple the radius, to find the circumference multiply it by the diameter, and the diameter is triple the length of the radius, are incorrect. The circumference of a circle is calculated as 2πr (two times the radius times Pi), and the diameter is twice the length of the radius, not triple.

Of the 250 cats in a local cat show, 73 are orange, 11 are white, 80 are black, 27 are calico, 50 are gray, and 9 are tuxedo. To the nearest thousandth, what is the probability a
randomly selected cat from the show will be gray or tuxedo?
Answer:
[tex]0.236[/tex]
Step-by-step explanation:
The total number of cats in a local cat show is 250
Of these, 73 are orange, 11 are white, 80 are black, 27 are calico, 50 are gray, and 9 are tuxedo.
The probability of a
randomly selected cat from the show will be gray or tuxedo is
[tex] = \frac{50}{250} + \frac{9}{250} [/tex]
We simplify to get:
[tex] = \frac{50 + 9}{250} [/tex]
[tex] = \frac{59}{250} [/tex]
[tex] = 0.236[/tex]
To find the probability of selecting a gray or tuxedo cat in a cat show, add the number of gray and tuxedo cats, then divide by the total number of cats.
The probability that a randomly selected cat from the show will be gray or tuxedo is calculated by adding the number of gray cats and tuxedo cats, then dividing by the total number of cats.
Number of gray cats = 50
Number of tuxedo cats = 9
Total number of gray or tuxedo cats = 50 + 9 = 59
Probability = Number of gray or tuxedo cats / Total number of cats
Probability = 59 / 250 ≈ 0.236

Answer:
NF = 16 units
Step-by-step explanation:
The in-center of a triangle is a point inside the triangle and equidistant from the three sides of the triangleIt is the center of the circle which touch the three sides of the triangle (each side of a triangle is tangent to the circle and the segments drawn from it to the points of tangent are radii of the circle)∵ N is the in-center of ΔABC
∴ N is equidistant from the sides AB, BC and CA
- That means the perpendicular segments from N to AB, BC
and AC are equal
∴ ND = NE = NF
∵ ND = 6x - 2
∵ NE = 3x + 7
- Equate them to find x
∴ 6x - 2 = 3x + 7
- Subtract 3x from both sides
∴ 3x - 2 = 7
- Add 2 to both sides
∴ 3x = 9
- Divide both sides by 3
∴ x = 3
- Substitute the value of x in ND to find its length
∵ ND = 6(3) - 2 = 18 - 2
∴ ND = 16 units
∵ ND = NE = NF
∴ NF = 16 units

Find the equation of the line that passes through the points (-800, 200) and (-400, 300).
Answer:
y=1/4x+400
Step-by-step explanation:
Slope=Rise/Run=(300-200)/(-400-(-800))=100/400=1/4
Now we have the slope, making our equation:
y=1/4x+b
We need b, the y-intercept, which we can use any ordered pair to plug in:
200=1/4(-800)+b
200=-200+b
400=b
So the equation that passes through the points (-800, 200) and (-400, 300) is: y=1/4x+400
The equation of line that passes through the points P(-800, 200) and Q(-400, 300) is y = x/4 + 400.
What is the general equation of straight line?
The general equation of straight line is -
y = mx + c
Given is a line that passes through the points P(-800, 200) and
Q(-400, 300).
First we will find the slope of the line -
m = (y₂ - y₁)/(x₂ - x₁)
m = (300 - 200)/(-400 + 800)
m = 100/400
m = 1/4
Now, the line passes through the point Q(-400, 300). Therefore -
300 = (1/4) x (- 400) + c
300 = - 100 + c
c = 400
The final equation of the line will be -
y = x/4 + 400
Therefore, the equation of line that passes through the points P(-800, 200) and Q(-400, 300) is y = x/4 + 400.
