10 black cards are removed from the pack
find the ratio of the number of red cards in the pack to the number of black cards in the pack
Give your answer in its simplest form
Please show your working out
Answers
Step-by-step explanation:
Ratio Red to Black is 1:1
Therefore, Red and Black has 25 cards respectively
If 10B cards are removed, then 25-10=15B cards left
Current ratio Red to Black is 25:15 and simplest form is 5:3

Step-by-step explanation:
The number 1032 is called the numerator or dividend, and the number 43 is called the denominator or divisor.
The quotient of 1032 and 43, the ratio of 1032 and 43, as well as the fraction of 1032 and 43 all mean (almost) the same:
1032 divided by 43, often written as 1032/43.
1032 divided by 43 in decimal = 24
1032 divided by 43 in fraction = 1032/43
1032 divided by 43 in percentage = 2400%
Note that you may use our state-of-the-art calculator above to obtain the quotient of any two integers or decimals, including 1032 and 43, of course.
Repetends, if any, are denoted in ().
The conversion is done automatically once the nominator, e.g. 1032, and the denominator, e.g. 43, have been inserted.
The quotient and remainder of 1032 divided by 43 = 24 R 0
The quotient (integer division) of 1032/43 equals 24; the remainder (“left over”) is 0.
1032 is the dividend, and 43 is the divisor.

I need help on a b and function 2
I dont get it
Answers
Answer:
For A: The first function has a greater ROC
For B: The first function has a negative slope
Step-by-step explanation:
Explication for A:
We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1
after substituting: (-3-(-6))/(0-(-1))
simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first
Explanation for B:
The first function described is f(x)=20-3.5x
This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.
The second function described is c(m)=5x+10
This is because the equation represents the total cost of renting a calculator, so both terms are positive.

Answers
From my understanding and your lack of a picture:
The triangle CAT has rotated in 90 degrees clockwise direction about the origin or 270 degrees counterclockwise direction about the origin.
Step-by-step explanation:
From the given figure it is noticed that the coordinates of the vertices of the pre-image are C(-2,1), A(-3,3) and T(1,1). The coordinates of the vertices of the image are C'(1,2), A'(3,3) and T(1,-1).
From these coordinates, we can conclude that the relation between the preimage and image is
If a figure rotated 90 degrees clockwise direction about the origin, then
Therefore triangle CAT is rotated 90 degrees clockwise direction about the origin or 270 degrees counterclockwise direction about the origin.

How many ways are there to put 5 balls in 2 boxes if the balls are distinguishable and the boxes are distinguishable?
Answers
Answer:
There are 243 ways but the balls in the boxes.
Step-by-step explanation:
There are 109375 ways to put 5 balls in 2 boxes when the balls and boxes are distinguishable by using counting principles and combinatorics
To solve this problem, use the concept of the multiplication principle, also known as the multiplication rule of counting.
Here's a step-by-step explanation:
Determine the number of choices for each ball: Since the balls are distinguishable, we have 5 choices for the first ball, 5 choices for the second ball, and so on, until we have 5 choices for the fifth ball. This can be represented as:
\(5 \times 5 \times 5 \times 5 \times 5.\)
Determine the number of choices for each box: Since the boxes are distinguishable, each ball can be placed in either box 1 or box 2. Thus, there are 2 choices for each ball. This can be represented as:
\(2 \times 2 \times 2 \times 2 \times 2.\)
To find the total number of ways, we multiply the number of choices for each ball with the number of choices for each box:
Total number of ways \(= (5 \times 5 \times5 \times5 \times5) \times(2 \times2 \times2 \times2 \times2)\)
On multiply gives:
= 3125\times 32 = 109,375.
Therefore, there are 109375 ways to put 5 balls in 2 boxes when the balls and boxes are distinguishable.

Formula of change: amount of change/ original amount *100.
500/4837*100= 11,397%
Answer: The percentage change is 16%.
Step-by-step explanation:
February:
4,100 water bottles.
March:
(4,100 + 7/100 x 4,100) water bottles
(4,100 + 287) water bottles.
4,387 water bottles.
April:
(500 + 4,387) water bottles.
4,887 water bottles.
= (4,887 - 4,100) / 4,887 x 100
= 787/4,887 x 100

What is an equation for the linear function whose graph contains the points (−1,−2) and a slope of 3?
Enter your answers in the boxes.
y+ ? = ? (x+1)
Answers
Answer:
The point-slope form of the equation of a line is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line. In this case, we have a point (-1,-2) and a slope of 3. Substituting these values into the equation, we get:
y - (-2) = 3(x - (-1))
Simplifying this equation, we get:
y + 2 = 3(x + 1)
So, the equation for the linear function whose graph contains the point (-1,-2) and has a slope of 3 is y + 2 = 3(x + 1).
Y + 2 = 3( X + 1 )
Explanation:
The equation is
Y - Y1 = M(X - X1)
Y1 is the y value:
The y value for the point (-1,-2) is -2 so we can plug that in
Y - (-2) = M( X - X1 )
If you subtract a negative you are adding so:
Y + 2 = M( X - X1 )
X1 stands for X
The X value for (-1,-2) is -1 same as the last one it will be positive because if you subtract a negative you are adding it:
Y + 2 = M( X + 1 )
Finally we plug in M
M is the slope and slope = 3 so plug 3 in
Y + 2 = 3( X + 1 )
Answer is Y + 2 = 3( X + 1 )

f(x) = −one eighth (x − 2)2 − 2
f(x) = one sixteenth (x − 2)2 + 2
f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2
Answers
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
f(x) = 1/16(x -2)^2 +2
