What is the probability that she picks a blue marble three times in a row?
According to the question
Samantha has a bag of 5 different colored marbles.
She randomly picks a marble from the bag, records the color, and returns it to the bag before picking another marble.
The probability of picking a bag one time is,
Number of bag pack at a time
Total number of bag
=1/5
The probability of picking a bag second time is,
Number of bag pack at a time Total number of bag
=1/5
The probability of picking a bag third time is,

The ratio of boys to girls in a class is
3:4. If there are 28 students
altogether in the class, how many of
them are girls?
Answer:
16 girls.
Step-by-step explanation:
Ignoring for a second the strict gender binary here, let's break down what this problem is telling us. A ratio of 3 boys to 4 girls means that for every 3 + 4 = 7 students, 3 are boys and 4 are girls. A class of 28 students is 4 times bigger than 7, so we can multiply each number in the ratio by 4 to get the count for this larger class. Doing that math, we find 3 · 4 = 12 boys and 4 · 4 = 16 girls.

Explanation: To find coordinates by a scale factor is by multiplying.
What we need to do is to multiply the coordinate points by the scale factor.
Find A' is use A 's coordinate. A 's coordinates are (0,4)
3 x 0 = 0
3 x 4 = 12
A' coordinates are : (0,12)

Which shows the equation of the line containing the point (–2, 6) and having a slope of 3 in slope-intercept form?
3y = x + 20
y=3x−20
y = 3x + 12
y=−32x+3
Answer:
y=3x+12
Step-by-step explanation:
Use this formula: y-y1=m(x-x1)
(y-Your y point=slope(x-Your x point)
Point= (-2, 6), Slope= 3
(Anything negative, you add. Anything positive, you subtract.)
Plug in your values: y-6=3(x+2)
distribute: y-6=3x+6
Add six to both sides of the equation:y-6(+6)=3x+6(+6)
We get our answer: y=3x+12

a fan does 65 rotations in 52 seconds how long does it take to do 200 rotations
Answer: 160 seconds
Step-by-step explanation:
First let us find the number of seconds per rotation
52 second/65 rotations
52/65
0.8 seconds/1 rotation
0.8 seconds per rotation
Now let us multiply 0.8 by 200 to get our answer
0.8 * 200
160
It takes 160 seconds to do 200 rotations
Answer:
160 seconds
Step-by-step explanation:
We have 65 rotations in 52 seconds, let's represent it like this:
[tex]\frac{52 seconds}{65 rotations}[/tex]
Now, let's multiply this by 200 rotations, and cancel out the rotations on the bottom:
[tex]\frac{52 seconds}{65 rotations} * 200 rotations[/tex]
See how there is rotations on both the top and bottom? This cancels both of them and leaves seconds!
Multiply the above equation and we get:
160 seconds or 2 minutes 40 seconds.
Hope this helps! Good luck and if you have questions please leave them in the comments!
Find the equation of the line of the given properties: Slope = 0 and passes through (-4,5).
Pls help me
Answer:
y = 5
Step-by-step explanation:
An equation can be written in two forms: point-slope form or slope-intercept form.
When you write an equation in point-slope form, you only need two things: a point and a slope.
Given:
point: (-4, 5)slope (m): 0The standard point-slope equation is
y - y₁ = m(x - x₁)
Plug in what you know.
y - (5) = 0(x - (-4))
Simplify.
y - 5 = 0(x + 4)
y - 5 = 0
y = 5
This is your equation.
Let's now represent this in slope-intercept form.
The standard equation is
y = mx + b
Plug in what you know.
5 = 0(-4) + b
Simplify.
5 = 0 + b
5 = b
Therefore,
y = 0x + 5 or y = 5

Answer:
€ 120Step-by-step explanation:
full price of the phone in terms of percentage
= 100%
percentage discount = (100-35)% = 65%
let the price of the phone before discount= X
therefore,
65%-----------78
100%----------X
cross multiplying
65×X = 100×78

In Chemistry class, Samantha finds that she can make a certain solution by mixing 0.04 liters of chemical A with 0.02 liters of water (this gives her 0.06 liters of the solution). She wants to make a total of 0.48 liters of this new solution. To do so, how many liters of water will she use?
Answer:
0.16 liters of water
Step-by-step explanation:
Samantha's recipe makes 0.06 liters of solution. She wants 0.48 liters of solution, an amount 0.48/0.06 = 8 times as great as made by one recipe.
The recipe calls for 0.02 liters of water. To make 8 times the amount of solution, Samantha will use 8 times as much water: 0.16 liters.
Samantha will use 0.16 liters of water to make 0.48 liters of solution.
__
Alternate solution
The fraction of solution that is water is (0.02 L)/(0.06 L) = 1/3. For 0.48 L of solution, the water needed is 1/3×0.48 L = 0.16 liters.

A term is a single number or variable, in this case, the number 2.
The sum in this equation would be 4x + 2.
The product is the result of multiplication, in this equation, the result of 5(4x + 2).
The factors are the digits that are being multiplied, in this case, 5 & 4x + 2
The quotient is the result of a division, in this case, the result of (4x + 2) / 7y.
A coefficient is a number that is being multiplied by a variable, in this case, 4 & y.
The composite figure shown is made up of 2 triangular prisms and one rectangular prism. If the area of each triangle base of the triangular prisms has an area of 24 m2, what is the total surface area of the composite figure? 120 m2 160 m2 760 m2 1,152 m2
The area of the composite figure is 1152 square meters
Complete QuestionA rectangular prism and 2 triangular prisms. The rectangular prism has a length of 20 meters, width of 6 meters, and height of 8 meters. The triangular prisms each have 2 triangular sides with a base of 6 meters and height of 8 meters. The rectangular sides are 20 meters by 6 meters, 20 meters by 10 meters, and 20 meters by 8 meters.
The composite figure shown is made up of 2 triangular prisms and one rectangular prism. If the area of each triangle base of the triangular prisms has an area of 24 m2, what is the total surface area of the composite figure?
How to determine the surface area?The given parameters are:
Rectangular prism :
Length = 20 meters; Width = 6 meters; Height = 8 meters
Triangular prism :
Triangular sides (2): Base = 6 meters; Height = 8 metersRectangular sides: 20 meters by 6 meters, 20 meters by 10 meters, and 20 meters by 8 meters.Base Area = 24 square meters:The area of the rectangular prism is:
Area = 2 * (Length * Width + Length * Height + Width * Height)
So, we have:
Area = 2 * (20 * 6 + 20 * 8 + 6 * 8)
Area = 656
The area of the triangular prism is:
Area = 2 * Base Area + Areas of Rectangular sides
So, we have:
Area = 2 * 24 + (20 * 6 + 20 * 10 + 20 * 8)
Area = 528
The common area between the prisms is:
Common area = 8 * 4
Common area = 32
Subtract the common area from the sum of the areas of the triangular prism and the rectangular prism to get the area of the composite figure
Composite figure = 656 + 528 - 32
Evaluate the sum
Composite figure = 1152
Hence, the area of the composite figure is 1152 square meters

Write the coordinates of the vertices after a rotation 270° counterclockwise around the origin.
Answer:
When rotating a rectangle 270° counter clockwise, you change the vertices in this way: (x,y) ---> (y,-x).
In other words, the "x" and "y" values switch, and the "x" becomes negative. If the "x" value is already negative, it becomes positive.

Answer:
m∠1 = 83
m∠2 = 97
m∠3 = 83
m∠4 = 97
m∠5 = 83
m∠6 = 97
m∠7 = 83
Step-by-step explanation:
When two lines are parallel,
Alternate interior angle are equal.Vertically opposite angles are equal.Sum of linear pair angles is 180.m∠8 = m∠4 = 97 ( Alternate interior angles )
m∠8 = m∠2 = 97 ( Alternate interior angles )
m∠6 = m∠4 = 97 ( Vertically opposite angles )
m∠2 and m∠3 are linear pair angles,
m∠2 + m∠3 = 180
97 + m∠3 = 180
m∠3 = 180 - 97
m∠3 = 83
m∠1 = m∠3 = 83 ( Vertically opposite angles )
m∠3 = m∠7 = 83 ( Alternate interior angles )
m∠7 = m∠5 = 83 ( Vertically opposite angles )
