If you roll one die, what is the probability of getting an odd number or a 4? Are the events inclusive or mutually exclusive?
Answer:
4/6
Step-by-step explanation:
The probability of getting an odd number or a 4 is,
⇒ P = 1/2
We have to given that,
Roll one die for the probability of getting an odd number or a 4.
Now, We know that,
Total outcomes are,
⇒ 1, 2, 3, 4, 5, 6
Hence, Odd numbers are,
⇒ 3, 5
So, The probability of getting an odd number is,
⇒ 2 / 6
⇒ 1 / 3
And, The probability of getting 4 is,
⇒ 1 / 6
Thus, the probability of getting an odd number or a 4 is,
⇒ P = 2/6 + 1/6
⇒ P = 3/6
⇒ P = 1/2

Consider these three squares with known area. 3 squares. The smallest square is labeled 25, the next square is 144, and the largest square is 169. Can a right triangle be formed using these squares?
Answer:
The answer is "5, 12, and 13".
Step-by-step explanation:
Please find the complete question in the attached file.
The right triangle is a triangle with only an angle of 90 degrees, as well as the go in the angle of 90 degrees, which is considered a hypotenuse.
The hypotenuse calculation square is equivalent to both the squared measures of the other two sides:
[tex]C^2=A^2+B^2[/tex]
And even those squares do verify the equation:
[tex]169 = 144 + 25[/tex]
So, it's a rectangular (right) triangle, with sides spanning [tex]5, 12, \ and \ 13.[/tex]

Step-by-step explanation: Hope this help :D
Answer:
A. 4x * 2x^2 + 4x * (-2) + 1 * 2x^2 + 1 * (-2)
Step-by-step explanation:
We have the binomial (4x + 1)(2x^2 - 2) and are asked to see how it looks like expanded.
When solving binomials, we need to follow the FOIL method :
First - First number in first parenthesis multiplied by first number in second parenthesis
Outer - First number in first parenthesis multiplied by second number in second parenthesis
Inner - Second number in first parenthesis multiplied by first number in second parenthesis
Last - Second number in first parenthesis multiplied by second number in second parenthesis
If we follow the definitions given, we can find our correct answer and also see where all the other answers mess up at :
A. 4x*2x^2+4x*(-2)+1*2x^2+1*(-2)
This follows FOIL entirely from start to finish.
B. 4x*2x^2+4x*(-2)+1*4x+1*(-2)
This did not follow the Inner part of FOIL.
C. 4x*2x^2+4x*(1)+1*2x^2+1*(-2)
This did not follow the Outer part of FOIL.

Explain how to use a number line to find the sum 7 + −2.
Step-by-step explanation:
start at 7 on the number line. move to the left (because the value is negative) 2 jumps. you will land on 5.
Answer: 5
Step-by-step explanation:
Usually you would just do 7+-2 which is also 7-2 which equals 5 but since it's a number line you do this
You would locate 7 on the number line and do the same for -2
Once done, you would take the distance 2 is from 0 and push 7 there(basically moving it to 5) and that would be how you would use a number line to find the sum of 7 + -2
Now if the 2 was positive, this would be different and you would add the distance making it 9 but since it's negative you push it towards 0 which makes it 5
I hope this helps!

Juana is measuring two pyramids whose base are isosceles right triangles. The second pyramid has the same height, but has 9 times the volume. What is the side length of its base
9514 1404 393
Answer:
3 times the smaller triangle base
Step-by-step explanation:
The volume is proportional to the height and to the area of the base.
If the height is unchanged, the larger pyramid must have a triangular base with an area that is 9 times the smaller base area.
Since the bases are similar, the area ratio is the square of the side length ratio. The side lengths of the larger base triangle must be √9 = 3 times the side lengths of the smaller base triangle.

Given: ∠AOB is a central angle and ∠ACB is a circumscribed angle. Prove: △ACO ≅ △BCO Circle O is shown. Line segments A O and B O are radii. Tangents C B and C B intersect at point C outside of the circle. A line is drawn to connect points C and O. We are given that angle AOB is a central angle of circle O and that angle ACB is a circumscribed angle of circle O. We see that AO ≅ BO because . We also know that AC ≅ BC since . Using the reflexive property, we see that . Therefore, we conclude that △ACO is congruent to △BCO by the .
Answer:
all radii of the same circle are congruent
tangents to a circle that intersect are congruent
side CO is congruent to side CO
SSS congruency theorem
Step-by-step explanation:
The triangle △ACO ≅ △BCO are congruent to each other by SAS postulate.
Given: ∠AOB is a central angle and ∠ACB is a circumscribed angle.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
We know that the radius and the tangent are perpendicular to each other.
Then the angle ∠CAO and angle ∠CBO are of 90°.
We know that the tangent of the circle drawn from the point outside the circle will be 2, and these tangent are of equal length.
In triangle △ACO ≅ △BCO, we have
CO = CO (Common side)
∠CAO = ∠CBO = 90°
OA = OB (Radius)
Thus, the triangle △ACO ≅ △BCO are congruent to each other by SAS postulate.

The whole numbers between 20 and 50 are 20, 24, 28, 32, 36, 40, 44, 45, 48.
What are whole numbers?A whole number is defined merely as any positive number that does not consider a fractional part or any decimal part of the numbers.
For example, the numbers 0, 1, 2, 3, 4, 5, 6, and 7 are all whole numbers. Numbers such as -9, 6.2, or 2 ½ are not whole numbers.
Therefore, the whole numbers that are on the gap between of 4 between 20 and 50 are the 20, 24, 28, 32, 36, 40, 44, 45, 48.

8. A welder is making a metal sphere. The radius will be 115 cm. What is the surface area of the metal sphere? Use 3.14 for π.
9. Thirty percent of the metal sphere will be covered in a metal that is tinted red. What is the area of the section of the sphere that is tinted red?
please help :))
Step-by-step explanation:
Given that,
8. The radius of a sphere, r = 115 cm
We need to find the surface area of the metal sphere. The formula for the surface area of a sphere is given by :
[tex]A=4\pi r^2[/tex]
Put all the values,
[tex]A=4\times 3.14 \times (115)^2\\\\=166106\ cm^2[/tex]
9. Thirty percent of the metal sphere will be covered in a metal that is tinted red.
So, the area of the section that is tinted red is :
[tex]A=30\%\ of\ 166106\\\\=\dfrac{30}{100}\times 166106\\\\=49831.8\ cm^2[/tex]
Hence, this is the required solution.

Probability refers to chances of occurrence of any event.
If a six-sided die is thrown, possible outcomes are [tex]1,2,3,4,5,6[/tex].
Billy needs to roll a 5 or higher to win the game.

The area of a square garden is 900m2. Find
its perimeter.
Answer:
120m
Step-by-step explanation:
Each side of square have same length, assume x for one side of square:
x^2=900
x=30
perimeter:30x4=120m
Answer:
120 square meters
Step-by-step explanation:
Since area is base times height and this is a square, we know all sides are the same length. Take the square root of 900 and you will get 30, meaning each side is thirty meters long. 30 x 4 = 120, that’s your perimeter. Hope this helps!
