Answer:
Step-by-step explanation:
To start with we can consider how many possibilities there are for the first card which is obviously 52, as any one of the cards in the deck can be found on the top of the pile. The next card is a bit trickier as there are only 51 possible cards that it could be as the first card takes up a spot. The third card now only has 50 possible cards it could and this continues all the way down to the last card.
is that good
A small theater had 9 rows of 25 chairs each. Workers just removed 6 of these chairs. How many chairs are left?
9 * 25 = 225
225 - 6 = 219
There are 219 chairs left.
Answer:
219 Chairs are left.
Step-by-step explanation:
[tex]\rightarrow[/tex] Each row has 25 chairs. And there are total 9 rows.
So, total number of chairs = 25×9
= 225
➾ Workers removed 6 chairs, so left number of chairs = 225-6
= 219 chairs.

answer for brainliest
Step-by-step explanation:
diameterfor first minute :
Circumference = 25.12
2πr = 25.12
22/7 × r = 25.12/2
r = 12.56 × 7 /22
r = 87.92/22
r = 3.99 mm ( approx. )
diameter = 2r = 2 × 3.99 = 7.98 mm
diameter for second minute =
circumference = 75.63
2πr = 75.63
πr = 75.63/2
r = 37.815 × 7/22
r = 264.705/22
r = 12.032 mm
diameter = 2r = 24.064 mm
COMPARISON : 24.064/7.98
3 times greater ( approximately )

Triangle PRQ was transformed to create triangle P'R'Q'. if point P started at coordinates (6,-54), and became point P' at coordinates (-6,-54), describe the transformation that was applied to triangle PRQ.
Answer:
PRQ was translated 90 degrees clockwise.
If (6,-54) is located in q4 (+,-) and rotated to land on (-6,-54) which is in q3 then it was rotated 90 degrees clockwise.

How many cubes with the side lengths of 1/3 ft completely fill the prism?
Answer:
48 cubes
Step-by-step explanation:
To begin, we must find the volume of both the cube and the rectangular prism.
The volume of a cube is a side to the 3rd power.
1/3 · 1/3 · 1/3 = 1/27
The volume of a prism is l * w * h.
2/3 · 1 · 8/3 = 16/9
Now, we have the volume of a cube and the prism. Since we have the find how many cubes can fit into the prism, we must divide 16/9 by 1/27.
16/9 ÷ 1/27 = 16/9 · 27/1 = 432/9 = 48/1 = 48
Therefore, 48 cubes will fit into the prism.
find the volume of this please.
Answer:
336 cubic feet

A muffin requires 1/8 a cup of sugar for 1/2 a batch. How many cups of sugar do you need to make 1 batch?
Answer:
1/4 or 2/8
Step-by-step explanation:
2/8 because you need to multiply by 2 witch 1/8 x 2 = 2/8 which is equal to 1/4
Answer:
1/4
Step-by-step explanation:
if 1/2 a cup requires an eighth of the sugar one batch will require two eighths, which is a quarter :1/8+1/8=2/8 which is 1/4
SOMEONE PLEASE HELPP!!
NEED HELP!!
which set of equations represents the system of linear equations shown on the graph?
The black line represents your equation from Question 7. Compare the black and blue lines.
Include in your answer:
*Slope-intercept form (y=mx + b) of the blue line. Show or explain your work.
*Which line has the greater slope? How do you know?
Hint: Find the y-intercept. Then count up and over (y/x) to the next point on the line to determine the slope.
Answer:
The black line has the greater slope.
Step-by-step explanation:
One way to think about which line has the greater slope is to imagine (or draw) a car on top of each line driving from left to right. If the car is driving up a steeper hill then the slope is greater.
To show your work though, starting at the y-intercept on the black line, find another point that you can see well on the line such as (3, 4). To get from the y-intercept to (3,4) go up 2 and right 3 so the slope is 2/3.
For the blue line, find a point that is easy to see such as (2, 3). To get from the y-intercept to (2, 3) go up 1 and right 2 so the slope is 1/2.
(Remember slope is y/x or rise/run)
Since 2/3 is bigger than 1/2, the slope of the black line is greater.

Classify each equation as defining y as a linear or nonlinear function of x. Select one cell per column.
Answer:
1. nonlinear
2. nonlinear
3. nonlinear
4. linear
5. linear
6. nonlinear
I think that is correct
Step-by-step explanation:
There is two ways you can do it.
1st . See if it is being multiplied, x cannot be the denominator, y cannot have a exponent and the x cannot be squared.
2nd - Use a graphing calculator and see if the line is straight, that is a linear equation and curved lines are nonlinear.
help me do examples for a function and a non function
Answer:
{(1,2) (3,4) (5,6)} and {(1,2) (1,4) (5,6)}
Step-by-step explanation:
you really want to think of a function as a vending machine. if you press B12 on a vending machine because thats where the chips are, only the chips should come out. in a function, the input value aka x (B12, what youre putting in) should only have one output value aka y, (the chips)
an example of a function would be {(1,2) (3,4) (5,6)}
an important thing to remember is that one output value can belong to multiple input values. there can be chips (output) in both B12 and C12 (inputs) BUT as i said before, there CANNOT be two outputs for one input. B12 cannot give you both chips and a drink.
using this, another example of a function would be {(1,2) (3,2) (5,2)}
an example of an non function would be {(1,2) (1,4) (5,6)} because x, the input value, has multiple output values which is not possible. the output of 1 can not be 2 and 4 at the same time which we can see in the (x,y) coordinates.

Answer:
Range = 7
Mean = 7.75
Assumption: Most students will have 7 or 10 letters in their last name
Step-by-step explanation:
Range = Largest - Smallest
= 10 - 3
= 7
Mean = Add the total numbers up to get a total / numbers in the series
= (3+5+2(6)+2(9)+5(7)+4(8)+5(10)) / (1+1+2+5+4+2+5)
= 7.75

Find the distance between [tex]\frac{7}{12}[/tex] and [tex]\sqrt{} \frac{16}{81}[/tex] on a number line. please show your work and explain it.
Answer:
5/36
Explanation:
Distance on a number line is basically difference between two numbers. So we subtract the two numbers. This can be solved on a calculator btw. 7/12 - √16/81 = 5/36.
