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
Line Ris represented by the equation y ==x+2. Line S is perpendicular to Line R, and passes through
the point (-6,4). What is the equation for Line S?
A. y =
B. y = x +6
C. y=-*-5
D. y = -x + 8
Answer:
y = -x - 2
Step-by-step explanation:
y = x + 2 {Compare with y = mx + c}
Slope = m1 = 1
Slope of the line S = m2 = -1/m1 = -1/1 = -1
(-6 , 4)
y -y1 = m (x -x1)
y - 4 = (-1)(x - [-6] )
y -4 = (-1)(x + 6)
y -4 = (-1)*x + (-1) *6
y - 4 = -x - 6
y = -x - 6 + 4
y = -x - 2

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

Consider this system of equations.
f(x)=x−4g(x)=−x−2
Plot the point that represents the solution to the equation f(x)=g(x).
We are given two functions.
[tex]f(x)=x-4\\g(x)=-x-2[/tex]
The point that represents the equation [tex]f(x)=g(x)[/tex], will also be the intersection of those two lines, meaning we can set the two equations equal to each other and solve for [tex]x[/tex].
[tex]f(x)=g(x)\\x-4=-x-2\\2x=2\\x=1[/tex]
Now that we are given the x value, we can plug this value back into either equation and solve for the y value.
[tex]f(1)=1-4\\f(1)=-3[/tex]
The point of intersection will be [tex](1,-3)[/tex].
Hope this helps!
Answer:

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
[tex]6^2=x(x+5)[/tex]
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.
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.
Which of these is equivalent to 2.75?
A. 2 3/4
B. 2 2/5
C. 2 1/5
D. 2 3/25
Answer:
2 3/4
Step-by-step explanation:
2=2
.75= 3/4
Example 75 cents is equal to 3 quarters
[tex]2 \frac{3}{4} [/tex]
Because 2.75 =
[tex] \frac{11}{4} [/tex]
And
[tex] \frac{11}{4} = 2 \frac{3}{4} [/tex]

Student B
Step-by-step explanation:
You know because:
The common factor between 3 and 6 is 3.
You can factor 2 x's from both parts and 2 y's.
Therefore, it would be
3x^2y^2.
work out: 0.03 x 0.6
0.03 x 0.6
= (3 x 6) / 1000
= 18 / 1000

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

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].

Answer:
-13
Step-by-step explanation:
Well, they do most of the work for you all you have to figure out is what is "1/5(-65)". To do this you have to turn 1/5 into a decimal so 1 divided by 5 which equals 0.2 then multiply that by -65. That will give you your simplified answer of -13.

A factory can build 15 cars every hour. If at a certain time of day , they have already built 9 cars,how many cars in total will they have built 5 hours from now?
Answer:
They would have built 84 cars
Step-by-step explanation:
From the question, they have already built 9 cars
Now, the hourly production rate is 15 cars per hour;
So therefore, in 5 hours, total that would have been built excluding the initial 9 will be;
15 * 5 = 75 cars
Now, let us add the initial 9
we have this as 9 + 75 = 84 cars
Choose Yes or No to tell whether the symbol will be reversed when the variable is isolated in each inequality. –10.5 < 3a b6 ≤ 7 –4.5c > 9 –215 ≤ –52d
Answer:
1). No, symbol won't be reversed
2.) No, symbol won't be reversed
3.) yes, symbol will be reversed
4.) No, symbol won't be reversed
Step-by-step explanation:
1.)
-10.5 < 3a
-10.5 /3 < 3a /3
-3.5 < 3 (No)
2.)
b/6 ≤ 7
Multiply both sides by 6
b/6 * 6 ≤ 7 * 6
b ≤ 42 (No)
3.)
-4.5c > 9
Dibide both sides by - 4.5
-4.5c / - 4.5 > 9/-4.5
c < 2 (yes)
4.)
–21/5 ≤ –5/2d
Multiply both sides by 2/5
-21/5 * 2/5 ≤ - 5/2d * 2/5
-21/2 ≤ - d
21/2 ≤ d (No)
