You have to have the 2 or 3 as the first digit.
After that, the other 3 digits can be done in 3! = 6 ways.
So, the total is 2*3! = 12
The number of ways the digits 0,1,2 and 3 can be permuted to give rise to a number greater than 2000 is 9.
What is permutation?A permutation is a word that describes the number of ways things can be ordered or arranged.
Given are numbers, 0,1, 2, 3
We asked for numbers greater than 2000, so those numbers will start either from 2 or 3.
2 _ _ _ = 3! = 6
3 _ _ _ = 3!/2! = 3
Hence, total possible ways are 6+3 = 9

fisrt second and the third terms of proportion are respectively 7 , 14 and 25 . Find its fourth term
Answer:
Check whether the two ratios form a proportion or not: (i) 6 : 8 and 12 : 16; (ii) 24 : 28 ... 3. The first, third and fourth terms of a proportion are 12, 8 and 14 respectively. ... 5. If a : b = 4 : 5 and b : c = 6 : 7; find a : c. Solution: a : b = 4 : 5. ⇒ a/b = 4/5.
Answer:
Let the fourth term be x
7/14=25/x
7x=14*25
x=350/7
x=50
Therefore the fourth term is 50

Emily attends a Film Festival. The admission fee is $10. Each movie ticket cost $5 each. Emily wants to determine how many movie tickets she can buy if she has a total of $40 before she pays the admission fee.
Answer:
Emily can buy 6 movie tickets after paying the admission fee
Step-by-step explanation:
Let x be the number of movie tickets
If each movie ticket costs 5 dollars then the cost of x movies will be 5x
And the admission fee will be a constant.
She has $40 in total
So the equation can be written as
[tex]10+5x = 40\\5x = 40-10\\5x = 30\\\frac{5x}{5} = \frac{30}{5}\\x = 6[/tex]
Hence,
Emily can buy 6 movie tickets after paying the admission fee
75% of the normal price of headphones is 45$. What's the normal price?
Answer:
60$ is the normal price.
Why:
Because if 45$ is 75%, then 30$ is 50%, 15 is 25%, and 0 is 0%. 50% + 50% = 100%. (That's how I did this one, anyway. This works on any 25%, 50%, or 75% problem.)

What is the equation of a line that passes
through (0.5, 4.25) and (2, 18.5) and has a
y-intercept of -0.5
Answer:y=9.5x-0.5
Step-by-step explanation:
Ok, so you need to use the equation y2-y1/x2-x1 to find the slope. So (18.5-4.25)/(2-0.5) so 14.25/1.5 , calculate that and you get 9.5 which is your slope, apply that to the slope formula which is y=mx+b where (m) is slope and (b) is y intercept and you get y=9.5x-0.5

Mia has $50 on a gift card to her favorite coffee shop. Each time she visits the coffee shop she spends $3.75 on her favorite drink. Write an equation to represent the relationship between x, the number of times she visits the coffee shop, and y, the total amount on her gift card.
Answer:
y=$3.75x
Step-by-step explanation:
$50 is equal to 'y'. 'x' is the number of days Mia goes to the coffee shop. For every day Mia goes to the coffee shop, she spends $3.75 on her favorite drink
The required expression for the balance gift card is y = 50 - 3.75x.
Given that,
Mia has $50 on a gift card to her favorite coffee shop. Each time she visits the coffee shop she spends $3.75 on her favorite drink. To determine an equation to represent the relationship between x, the number of times she visits the coffee shop, and y, the total amount on her gift card.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Total money spent on the drink = 3.75x
Money left in the gift card after paying 3.75x from the $50 gift card is = 50 - 3.75x.
So,
y = 50 - 3.75x
Thus, the required expression for the balance gift card is y = 50 - 3.75x.
