Answer: The width of the border is 1 inch
Step-by-step explanation:
The area of the paper is
A = 5 in* 7in = 35 in^2
The area of the photo is 24 in^2
The difference in the area is 35 in^2 - 24in^2 = 11in^2
knowing that the inside area is of 24 in, we can write it as a product of two numbers, let's use x*y = 24
then we have that:
(7 -x)*(5 - x) = 24
where x is the width of the borders.
35 - 5x - 7x + x^2 = 24
x^2 - 12x + 11 = 0
the solutions are for this quadratic equation are:
so we have two solutions
x = (12 + 10)/2 = 11
this can not be the correct option, because the border will be larger than the actual paper, so we can discard this solution of the quadratic equation.
x = (12 - 10)/2 = 1
this is the correct answer, we found that the width of the border is 1 inch.
then we have:
(7 in - 1 in)*(5 in - 1in) = 6in*4in = 24in^2
Original price of the video game = $42
Percentage of discount = 25%
Amount of discount = 42 * (25/100) dollar
= 42 * (1/4) dollar
= (42/4) dollar
= (21/2) dollar
= $ 10.5
Actual sale price of the video game = (42 - 10.5) dollar
= 31.5 dollar
So we come to know that the amount of discount given is $10.5 and the sale price of the video game is $31.5
Honestly idek I just need points
James bought 12 cookies and ate 3
3/12 = 1/4
1/4 = 0.25
0.25 = 25%
James ate 25% of the cookies
hope this helps
Answer: Less than one pizza or 4/5 of a pizza
Step by Step Explanation:
If you're trying to give a product with a certain amount and theres more people who want it than the product then it's going to be less than 1; in this equation you would be doing 4 divided by 5 or 4/5 or 0.8.
Explanation for the Teacher: Since there is more people than pizza's then the number is going to be less than 1, then if you want to share 4 pizzas with 5 kids you have to put the pizzas over the kids with fractions and it's 4/5.
