A number cube is labeled 1 through 6. What is the probability of NOT
rolling a 2?
Answer:
Step-by-step explanation:
each of the 6 number has a 1/6 chance of being rolled
1 2 3 4 5 6
1/6 1/6 1/6 1/6 1/6 1/6
Every time the cube is rolled there is a 6/6 chance of any number comes up
1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 6/6 or 1
What is the probability of NOT rolling a 2? Any other number
1 2 3 4 5 6
1/6 + 0 + 1/6 + 1/6 + 1/6 + 1/6 = 5/6 or 0.8333
find the domain and range of relation of 3x + y =3
Rewrite the equation in the slope-intercept form.
3x + y = 3
Subtracting -3x from both sides we get this:
y = -3x + 3
This is just a straight line.
Here, x can be any real number.
When x is any real number, the value of y is also any real number.
A straight line goes on forever in two directions. It really does not matter what number we select for x to find y.
Answer:
Domain is ALL REAL NUMBERS.
Range is ALL REAL NUMBERS.
Your math book may write the answer in interval notation:
Domain is (-00, 00); Range is (-00, 00).
Note:
-00 means negative infinity.
00 means positive infinity.
Still in some math books, the author(s) may decide to use set notation to express ALL REAL NUMBERS for the domain and range.
If so, we can also write the answer this way:
Domain = {x| x = ALL R}, where big R stands for real numbers.
Range = {y| y = ALL R}, where big R stands for real numbers.
Which property is demonstrated below?
a + b = b + a
Answer:
Commutative Property
Step-by-step explanation:
The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.
Answer:
Commutative property of addition

Nolan and Mia work at a dry cleaners ironing shirts. Nolan can iron 25 shirts per hour, and Mia can iron 35 shirts per hour. Mia worked twice as many hours as Nolan and they ironed 380 shirts between them. Determine the number of hours Nolan worked and the number of hours Mia worked.
Answer: Nolan worked 4 hours, and Mia worked 8 hours
Step-by-step explanation:
Step-by-step explanation:
Let x represent the number of hours Nolan worked.
Let y represent the number of hours Mia worked.
Mia worked twice as many hours as Nolan. This means that
y = 2x
Nolan can iron 25 shirts per hour, and Mia can iron 35 shirts per hour. Together, Nolan and Mia ironed 380 shirts between them. This means that
25x + 35y = 380 - - - - - - - - - - - - - -1
Substituting y = 2x into equation 1, it becomes
25x + 35 × 2x = 380
25x + 70x = 380
95x = 380
x = 380/95
x = 4
y = 2x = 2 × 4
y = 8

Step-by-step explanation:
The given triangle is an isosceles right triangle, meaning that the 45-45-90 triangle side rule applies. The 45-45-90 triangle side rule states that the two legs (sides that are adjacent to the right angle) are congruent, and the hypotenuse (the side opposite the rights angle) is equal to the leg times the square root of two. Using this property, one knows that the leg is equal to the hypotenuse divided by the square root of two. In this problem, the hypotenuse is equal to (1), and the leg is equal to (x). Therefore, one can say,
[tex]x = \frac{1}{\sqrt{2}}[/tex]
Rationalize the denominator,
[tex]\frac{1}{\sqrt{2}}*\frac{\sqrt{2}}{\sqrt{2}}\\\\\frac{\sqrt{2}}{2}[/tex]
Answer:
Step-by-step explanation:
a² + b² = c² look familiar? it is the Pythagorean theorem
both side are the same length since both angles are the same some sort of Isosceles triangle rule I think so side 1 = x side 2 = x and hypotenuse = 1
x² + x² = 1²
2x² = 1
x² = 1/2
x = √(1/2) the denominator is NOT rational in this FORM
x = √1 / √2 multiple the numerator and the denominator by √2
x = 1 (√2) / (√2)(√2)
x = √2 / √2²
x = √2 / 2 finding a rational denominators means nothing
just do more work and more typing for me,
a silly MATH rule
x = √2/2 = 0.7071 x = √(1/2) = √(0.5) = 0.7071 the SAME Number

A metal bar has a mass of 960g and a volume of 120cm³. Find the density of the metal in the bar.
Answer:
Density = 8g/cm³
Step-by-step explanation:
Density = Mass/Volume
Given the following
Mass = 960g
Volume = 120cm^3
Substitute
Density = 960g/120cm^3
Density = 8g/cm³
Ms. Hernandez has $150.00 to spend on parking and admissions to the zoo. The parking will cost $15.00 and admission tickets will cost $9.00 per person, including tax. Determine the maximum number of people that she can bring to the zoo. *
give brainleist
The answer is Ms Hernandez can bring up to 6 people to the zoo.
x - the number of people that she can bring to the zoo
The parking will cost $7: a = 7
Admission tickets will cost $15.50 per person: b = 15.50x
She can spend on parking and admission tickets $100:
a + b ≤ 100
a = 7
b = 15.50x
7 + 15.50x ≤ 100
15.50x ≤ 100 - 7
15.50x ≤ 93
x ≤ 93 / 15.50
x ≤ 6

Hi I need help with this hope someone has the answer.A triangular window is above the door to a café. The length of the base of the window is 12 feet, and the height is 10 feet
What is the area of the window?
Answer:
the answer is 60
Step-by-step explanation:
12×10=120
120÷2=60
Step-by-step explanation:
Sample Response: The height of the triangle will be twice the height of the rectangle. The area of a triangle is ½ bh and the area of a rectangle is bh. If the bases are the same, then the height of the triangle has to be double that of the rectangle in order to get the same area.

GEOMETRY. I will give brainliest
Given:
A figure of a circle. A secant and tangent of the given circle.
To find:
The correct equation.
Solution:
According the intersecting tangent secant theorem, the square of tangent is equal to the property of external segment of secant and the measure of the secant.
Using intersecting tangent secant theorem, we get

It can be written as
[tex]x(x+5)=6^2[/tex]
The required equation is [tex]x(x+5)=6^2[/tex].
Therefore, the correct option is B.

A dog walks due east 180 ft to a corner.
After turning through an angle of 81.5°,
the dog walks 329 ft. to the second
corner. Then the dog walks back
to the starting point.
What is the area of the triangle
formed by his path?
Area = [?] ft.2
Round to the nearest hundredth.
Answer:
Area = 29284.87 ft²
Step-by-step explanation:
I've drawn a triangle to depict the movement of the dog with the angle and dimensions.
From the attached triangle, we see that the starting point is C, the first point is A and the second point is B.
Let's find the third side from the image using law of cosine.
Thus;
b² = a² + c² - 2ac cos B
Thus;
b² = 180² + 329² - 2(180 × 329)cos 81.5
b² = 32400 + 108241 - 17506.55
b² = 123134.45
b = √123134.45
b = 350.91 ft
We calculate the area of the triangle using heron's formula.
Area = √(p(p − a)(p − b)(p − c))
Where p = (a + b + c)/2 = (180 + 350.91 + 329)/2 = 429.955 ft
Area = √(429.955(429.955 - 180)(429.955 - 350.91)(429.955 - 329)
Area = 29284.886 ft²
To the nearest Hundredth gives;
Area = 29284.87 ft²

29284.76

Answer:

Step-by-step explanation:
-5 | 6n +15 | +2 = - 43
Answer:
n=-1 or n=-4
Step-by-step explanation:
-5/6n + 15/ = -45
/6n + 15/ = 9
square both sides to neutralize absolute value
/6n + 15/^2 = 81
36n^2 + 180n + 225 = 81
divide both sides by 9
4n^2 + 20n + 25 = 9
4n^2 + 20n + 16 = 0
divide both sides by 4
n^2 + 5n + 4 = 0
Factorize
(n + 1)(n + 4) = 0
therefore n = -1 or -4

Answer:
Step-by-step explanation:
1/11 = 0.09090909
2/9 = .2222222222
1/10 is certainly between these two numbers.
1/10 is 0.1 which is larger (just) than 1/11 but a good deal smaller than 2/9
1/20 = 0.05 which is just bigger than 1/11 but much smaller than 2/9. There are many numbers that would fit between 1/11 and 2/9
Sadiq measured the dimensions of a 1 kg bag of sugar and found the length was 9.2 cm, the width was 6 cm and the height was 14.1 cm.
Calculate the density of the sugar in g/cm3
Answer:
[tex]d=1.28\times 10^{-6}\ g/cm^3[/tex]
Step-by-step explanation:
The mass of a bag of sugar, m = 1 kg = 0.001 g
Length of bag, l = 9.2 cm
Width of bag, b = 6 cm
Height of the bag, h = 14.1 cm
We need to find the density of the sugar bag.
Density = mass/volume
So,
[tex]d=\dfrac{0.001\ g}{9.2\times 6\times 14.1\ cm^3}\\\\d=1.28\times 10^{-6}\ g/cm^3[/tex]
So, the density of the bag is [tex]1.28\times 10^{-6}\ g/cm^3[/tex].
