Since the value of y varies directly with x, the value of x when y equals 9 is [tex]\frac{9}{13}[/tex]
Given the following data:
x = 195y = 15To find the value of x when y = 9:
This is a direction proportion exercise and you're required to solve for the value of x when the value of y is equal to 9.
First of all, we would determine the constant of proportionality (k) for the mathematical expression.
[tex]y = kx\\\\15 = 195k\\\\k = \frac{195}{15}[/tex]
k = 13
Now, we can find x:
[tex]y = kx\\\\9 = 13x\\\\x = \frac{9}{13}[/tex]
Therefore, the value of x when y equals 9 is [tex]\frac{9}{13}[/tex]

A collection of coins is worth $4.40 and is made up of nickels and dimes. If there are 75 coins total, how many dimes are in the collection?
Answer:
5.00
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
the nickels can add up to 60 nickels for 3$. then, i just started adding dimes until i get to $1.30 out of the remaining $1.40 (because we subtracted $3 from 60 nickels). we now have 73 coins. two more nickels adds 0.10, which finally gets us to the missing 1.40.
this probably didn't make sense, but I'm 98% sure its right.
Nicole has a pack of playing cards & she chooses a card at random. what is the probability that she picks an ace?
Give your answer as a fraction in its lowest form
Answer:
1/13 (1 in 13)
Step-by-step explanation:
so, there's 4 aces in a standard deck of 52 cards.
so far, we can see this as 4/52 (4 in 52)
these are both divisible by 2, lets go ahead and simplify that to 2/26
still divisible by 2. this then becomes 1 /13
so, she has a 1/13 (1 in 13) chance to get an ace.

Write a quadratic equation in STANDARD FORM given the roots:
1, 1/2
Answer:
f(x) = 2x^2 - 3x + 1
Step-by-step explanation:
The root 1 is associated with the factor (x - 1).
The root 1/2 is associated with the factor (x - 1/2), which in turn is equivalent to (2x -1)
The quadratic in question is f(x) = (x - 1)(2x - 1). To write this in standard form, perform the indicated multiplication:
f(x) = 2x^2 - 2x - x + 1, or f(x) = 2x^2 - 3x + 1
A jar has 20 marbles: 3 green, 12 blue, 5 red.
What is the probability of randomly choosing a red and then a green marble (keep the red marble when you choose it)?
Probability is defined as the likelihood or the certainty that an event is going to occur or happen.
The probability of randomly choosing a red and then a green marble is [tex]3/76[/tex].
The total number of marbles = 20
The number of green marbles= 3
The number of blue marbles = 12
The number of red marbles = 5
The probability of choosing a red marble = Number of red marbles / Total number of marbles
= 5/20
In simplest fraction form = [tex]\frac{1}{4}[/tex]
We are told in the question that you keep the red marble you choose, So this means the total number of marbles left reduces to 19
The probability of choosing a green marble is = Number of green marbles / New total number of marbles
= 3/19
Therefore, the probability of randomly choosing a red and then a green marble is
P (Red) x P(Green)
= 1/4 x 3/19
= [tex]3/76[/tex]

A sum of $30,400 is to be divided in to three shares in the ratio of 4 : 5 : 7. Find the largest share. Please emergency
Answer:
$13,300
Step-by-step explanation:
$30,400 in to the ratio of 4:5:7
First lets add 4, 5, and 7:
4 + 5 + 7 = 16
Now divide 30,400 by 16 to find 1 share:
30,400/16 = 1900
Since the largest share is 7, we multiply 1900 by 7, since 1900 is equivalent of 1 share
1900 x 7 = 13300
