The perimeter of an airplane ticket is 30 centimeters. The area is 50 square centimeters. What are the dimensions of the ticket?

Answers

Answer:

The length can be 5 and the width 10.

Step-by-step explanation:

perimeter is equal to 2L + 2W

area is equal to L * W

you get 2 equations:

30 = 2L + 2W

50 = L*W

we'll solve by substitution.

you can use either equation to solve for either variable.

we'll use the second equation to solve for L.

second equation is:

50 = L*W

divide both sides of this equation by W to get:

L = 50/W

we now have a value of L that we can substitute in the first equation which we can then use to solve for W.

the first equation is:

30 = 2L + 2W

replace L with 50/W to get:

30 = 2*(50/W) + 2W

simplify to get:

30 = 100/W + 2W

multiply both sides of this equation by W to get:

30W = 100 + 2W^2

subtract 30W from both sides of this equation to get:

2W^2 - 30W + 100 = 0

factor this equation to get:

(2W - 20) * (W - 5) = 0

solve for W to get:

W = 10 or W = 5

if W = 10, then use the equation of 50 = L*W to get L = 5

if W = 5, then use the equation of 50 = L*W to get L = 10

you have 2 possible solutions.

L = 5 and W = 10 or:

L = 10 and W = 5

both are plausible so we'll test them both out.

when L = 5 and W = 10:

the first equation becomes 2*5 + 2*10 = 10 + 20 = 30

the second equation becomes 5*10 = 50

both equations confirm that the solution of L = 5 and W = 10 is good.

when L = 10 andW = 5:

the first equation becomes 2*10 + 2*5 = 20 + 10 = 30

the second equation becomes 10*5 = 5

both equations confirm that the solution of L = 10 and W = 5 is good.

the ticket can have either:

a length of 5 and a width of 10 or:

a length of 10 and a width of 5.

since the length is usually longer than the width, you are free to choose that the ticket most likely has a length of 10 and a width of 5.

alternatively, you can simply say that the dimensions are 5 by 10 and let the recipient of that information determine which is the length and which is the width.

mathematically, the length can be 10 and the width 5 or the length can be 5 and the width 10.

So Nelly gets £8 an hour for the first 15 hours, so you have to find the product of 8 and 15 which is £120. Then she gets an extra £10 for every extra hour, so we have tl subtract 15 hours from how many total she worked. To do that, we first have to add all of the hours together which would be 22 hours. Then we have to subtract the 15 which is 7 hours. However, the 5 hours on Saturday are going to pay double so we will calculate that afterwards. so 7 minus 5 is 2. Nelly gets paid £8 pounds for every hour so she gets £16 for 2 hours. Now, since are doubling £8 we get £16. So Nelly gets paid £16 an hour for the hours she worked on Saturday. 5 times 16 is £80. Now we add it all together. £120 + £16 + £80 = £216

Step-by-step explanation:

42 degrees is 42 “points” away from zero (picture a number line). -3 degrees is 3 points away from zero on the number line, but in the opposite direction. The two numbers are 45 “points” away from each other.

When they say find the difference, it’s a subtraction equation.

What is the solution to this system?

Answers

Answer: There is no solution

Step-by-step explanation:

The system of a systems of equations on a graph is the coordinate where the 2 lines intersect, or come together. In this picture, the 2 lines don't intersect at a point, so there is no solution. Here are some rules for systems of equations on a graph:

How to know if it has 'infinite' solutions: If it has infinite solutions, the 2 lines share the same points. In other words, they are basically just on top of each other, or in the exact same spot.

How to know if there are 'no solutions': The 2 lines never come together (intersect). This is true in this graph because they are always apart.

How to know if there is 'one solutioin': The 2 lines cross each other, come together, or intersect (all the same meaning), at 1 point .

Do the calculation below

6(18 + 14)

Answers

Answer:

Explained below...

Step-by-step explanation:

First, recognize the acronym PEMDAS, which stands for:

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

So, as there are parenthesis, that will be your first step in the expression.

6(18 + 14) --> 6(32)

Now, you will find the next step in PEMDAS, which would be multiplication.

6 * 32 = 192.

So, your answer for the equation is 192.

PHOTOGRAPHY Joseph subscribes to a website for processing his digital pictures. The subscription is $8 and 5-by-7-inch prints are $0.15 each. How many prints does Joseph purchase if the charge for January is $11?
help now i beg i will give brainlist plz

Answers

The answer is 20 prints.

Explanation:
The total cost is $11. Joseph paid $8 for the SUBSCRIPTION (NOT PRINTS) already, so we take away the 8 from 11, equaling in $3 left.
The question is asking for the amount of prints. Now that we only have 3 dollars left, we just divide that by the cost of each print (0.15) to see how many prints can go into that cost.
3 divided by 0.15 is 20. So, Joseph purchased 20 prints.
