y is inversely proportional to x . When y = 30 , x = 3 Work out x when y = 6
Answers
Step-by-step explanation:
yx = k, where k is a real constant.
When y = 30, x = 3.
=> k = (30)(3) = 90.
Hence when y = 6, x = k/y = (90)/(6) = 15.

Answers
Answer:
C. 5/24
Step-by-step explanation:
John = 3/8
Tim = 1/3
Kevon = ?
---------------------------------
3/8 = 0.375
1/3 = 0.333
0.375 + 0.333 = 0.708
0.292 is left
---------------------------------
5/8 = 0.625 - wrong
9/24 = 0.375 - wrong
5/24 = 0.208333 = 0.293
10/24 = 0.416667 - wrong

Answer:
y = -5/3x -13/3
Step-by-step explanation:
In any "solve for ..." problem, it is useful to start by identifying where the target is and what has been done to it. Here, y is in one term on the left side of the equation and it has had these things done to it:
multiply by -3add -5xWe want to undo these in reverse order. We undo addition by adding the opposite. We undo multiplication by multiplying by the reciprocal (equivalently, dividing). Whatever we do to one side of the equation, we must also do to the other side.
So, first we add the opposite of -5x to both sides of the equation.
-5x +5x -3y = 13 +5x
-3y = 13 +5x . . . . . . . . . collect terms
Next, we undo the multiplication by -3. We can do that by multiplying both sides by 1/(-3) = -1/3.
(-1/3)(-3y) = (-1/3)(13 +5x)
y = -5/3x -13/3 . . . . . also we rearranged the terms to standard form

Consider all four-digit numbers that can be made from the digits 0-9 (assume that numbers cannot start with 0). What is the probability of choosing a random number from this group that is less than or equal to 5000
Answers
Answer: 0.44
Step-by-step explanation:
First, let's count the total number of four-digit numbers.
Let's think it as four empty slots:
_ _ _ _
In each slot, we can put a single digit.
In the first slot, we have 9 options {1, 2, 3, 4, 5, 6, 7, 8, 9}
The zero is not an option here, because if there was a 0, this would be a 3 digit number, then the 0 can not be in the first slot.
For the second slot we have 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
for the third slot we have 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
for the fourth slot we have 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
The total number of combinations is equal to the product between the numbers of options for each slot, this means that we have:
Combinations = 9*10*10*10 = 9000
So there are 9000 different 4 digit numbers.
Now we want to find the probability of selecting a number at random that is equal or smaller than 5000.
Let's see the number of 4-digit numbers that are equal or smaller than 5000.
The smallest 4-digit number is 1000.
Then the number of numbers between 1000 and 5000 is:
5000 - 1000 = 4000
This means that there are 4000 4-digit numbers that are equal or smaller than 5000.
Now, the probability of selecting one of them at random is equal to the quotient between the number of 4-digit numbers that meet the condition (4000) and the total number of 4-digits (9000)
Then te probability is:
P = 4000/9000 = 4/9 = 0.44

What is the length of the reduced photo?
What is the length of the reduced photos
4in
3.75 in
5.25 in
5.60 in
Answers
Answer: 5.60 in
Step-by-step explanation:
4 / 5 = x / 7 Multiply both sides by 7
28/5 = x Divide 28 and 5
5.6 = x
So the answer would be 5.60 inches.
The length of the reduced photo will be 5.60 in.
What is proportion?A proportion is a comparison of two numbers that each represent the parts of a whole.
Given that, An 5 in. by 7 in. photo is reduced so that the width is 4 in
Since, there is a reduction occurring then the new and original dimensions will be in equal proportion,
Therefore,
4 / 5 = x / 7
28/5 = x
5.6 = x
x = 5.6
Hence, the answer would be 5.60 inches.
