Y is 1 1/3 times x.
Which ratio is equivalent to y : x ?
A. 3:3
B. 4:3
C: 7:3
D: 3:7
Answer:
B. 4:3
Step-by-step explanation:
Note: I use the '&' mark to symbolize mixed fractions, since it's easy to mistake the whole number for part of the numerator. Don't do this for assignments, as it's not proper.
1 & 1/3 = 4/3
Thus, the answer is B. 4:3.

Answer:
16 inches
Step-by-step explanation:
The tile is rectangular, so the other 2 sides have lengths 2in and 6in.
The perimeter is 2in + 6in + 2in + 6in = 16in
Answer:
16
Step-by-step explanation:
the long sides are both 6 inches
6+6=12
the short sides are both 2 inches
2+2=4
add all the sides together
12+4=16
Suppose you have a bag with 10 black and 10 red balls, with the balls of each color numbered 1 to 10. Suppose you pick two balls uniformly at random from the bag.
a. Show that the probability that you pick a ball of each color is 10/19.
b. Show that the probability that you pick a ball of each color, with the number on the red ball being one less than the number on the black ball, is 9/190.
Answer:
Step-by-step explanation:
[tex]\text{From the given information:}[/tex]
[tex](a)[/tex]
[tex]\text{ P(ball of each color)=P(1st ball is black \& 2nd (red)) + P(1st(red) \& 2nd(black)})[/tex]
[tex]\text{ P(ball of each color)} = {P(1st (black) \times P(2nd \ red \ | \ 1st black) }+P(1st \ red) \times P(2nd \ black \ | \ 1st \ red)}[/tex]
[tex]\text{ P(ball of each color)} = \Big(\dfrac{10}{20}\Big ) \times \Big(\dfrac{10}{19}\Big ) + \Big(\dfrac{10}{20}\Big ) \times \Big(\dfrac{10}{20}\Big )[/tex]
[tex]\text{ P(ball of each color)} = \Big(\dfrac{10}{19}\Big )[/tex]
[tex](b)[/tex]
[tex]\text{If the combination of total no. of black \& red balls with no =10*10 =100}[/tex]
[tex]Then;[/tex]
[tex]\text{the no. of ways red is less than no. of black = 9}[/tex]
[tex]Thus:[/tex]
[tex]\text{P(ball of each color and number on red ball is 1 less than number of black ball is :)}[/tex][tex]= \text{P(ball of each color) * P(red is 1 less than black [] ball of each color)}[/tex]
[tex]=\Big( \dfrac{10}{19}\times \dfrac{9}{100} \Big )[/tex]
[tex]= \dfrac{9}{190}[/tex]

What is 3-6? Please help meeeee
your answer is going to be -3
Answer:
The Answer to 3-6 is -3!
Step-by-step explanation:
Think of it as a regular problem at first, 6-3: Switch the rolls!
6-3= 3 So when you switch the numbers back to 3-6, you get -3.
The answer has to have a negative sign (-) because it is a negative, a number below zero.
3-3= 0, 3 is half of 6, 6 is the number you need to subtract so you have to go below zero because subtraction is all about taking away from that first number. So 3-3= 0, 0-3= -3.
Hope that helped you!

Reset
Answer:
A. 0, - 9
Step-by-step explanation:
Given
x² + 9x = 0
x (x + 9 ) = 0
Either
x = 0
or,
x + 9 = 0
x = - 9
Hope it will help :)
The values of x that satisfy the equation x² + 9x = 0 are x = 0 and x = -9.
Option A is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
x² + 9x = 0
To solve for x, we can factor the expression:
x(x + 9) = 0
According to the zero product property, this equation is satisfied if either x = 0 or x + 9 = 0.
We have two solutions:
x = 0 or x = -9
Therefore,
The values of x that satisfy the equation x² + 9x = 0 are x = 0 and x = -9.

Step-by-step explanation:
x-9=15 will equal to 24 so x=24
if Allison is 15 but she is 9 years younger then Pam, Pam is x, so all you have to do is count up from 15, so 15+9 which equals 24 Pam is 24 making F the right choice

please solve this class 10 function
if f={(x,y):3y-2x=6} find f-¹(x)
Answer:
f −1 (x)= x/2+3
Step-by-step explanation:
Here take y=f(x)
Then y=2x−6
⇒2x=y+6
⇒x= y/2 +3
Now switch x and y in the resulting equation. The resulting function of x is the inverse.
⇒y= x/2 +3
Thus the inverse function is f −1 (x)= x/2+3
There were 52 riders on a bus. The next bus had 25% more riders. How many riders were on the next bus?
Answer:
65 riders
Step-by-step explanation:
52 times 0.25 = 13 (25% of 52)
52 + 13 = 65
Answer:
There were 65 riders on the next bus.
Step-by-step explanation:
To solve this you have to know what 25% of 52 is, and since 25% of 52 is 13, you have to add 52 and 13 so you get 65 as your result.
