Solve for L.
P = 2L + 2W


L = 2/(P - W)
L = 2(W - 2P)
L = (P - 2W)/2

Answers

Answer:

L = (P - 2W)/2

Step-by-step explanation:

This is the formula for perimeter

P = 2L + 2W

Sustract 2W on both sides:

P-2W= 2L

Divide both sides by 2:

(P-2W)/2 = L

L= (P-2W)/2

What is the final amount if 1885 is increased by 5% followed by a further 18% increase

Answers

9514 1404 393

Answer:

  2335.515

Step-by-step explanation:

The first increase multiplies the original amount by 1 + 5% = 1.05.

The second increase multiplies the already increased amount by 1 + 18% = 1.18.

Then the final amount is ...

  1885(1.05)(1.18) = 2335.515

3) Solve this system of linear equations by elimination.

y=x-1
2x-y=0

*x=-1,y=-2
*x=1,y=2
*x=2,y=1
*x=-2,y=-1

Answers

Answer:

Solving this system of linear equations by elimination we get x=-1 and y=-2

Option 1 is correct option.

Step-by-step explanation:

We are given equations:

[tex]y=x-1---eq(1)\\2x-y=0---eq(2)[/tex]

We need to solve by Elimination method.

Elimination method: Add or subtract the equations to get an equation in one variable.

Rearranging the equation 1 we get

[tex]-x+y=-1---eq(1)\\2x-y=0---eq(2)[/tex]

Add eq(1) and eq(2)

[tex]-x+y=-1\\2x-y=0\\------\\x=-1[/tex]

So, after eliminating y we get x=-1

Now finding y by putting x in eq(1)

[tex]y=x-1\\y=-1-1\\y=-2[/tex]

We get y=-2

So, solving this system of linear equations by elimination we get x=-1 and y=-2

Option 1 is correct option.

In 1974 a mother was 6 times as old as her daughter. If the mother turned 50 in the year 2000, in what year was the mother double her daughter’s age?

This is in the topic of linear equations and please provide an explanation. (The working out)

Answers

Answer:

1990

Step-by-step explanation:

Since the mother was 50 years old in 2000, she was 50 - (2000-1974) = 50 - 26 = 24 years old in 1974.

Hence, the daughter was 24/6 = 4 years old in 1974.

In "x" years after 1974, the daughter will be 4+x years old, while the mother will be 24+x years old.

We need to find "x" from the equation

2(4 + x) = 24+x.

8 + 2x = 24 + x,

x = 24 - 8 = 16.

1974 + 16 = 1990.

Answer In 1990 the mother doubles her daughter's age

Check In 1990 mother's age is/was 24 + 16 = 40 years.

In 1990 the daughter's age is/was 4 + 16 = 20 years.

In the year 2000 the mother was 50 so that means that in the year 1974 she was 24. If in 1974 she was 6x as old as her daughter then her daughter was 4 years old. Her daughter is 30 in the year 2000 so the year the mothers age was double her daughters age is before 2000 and after 1974. But since we know that in 2000 mom was 50 and daughter is 30 we can take 10 years from both to have 40 and 20. 40 is double of 20 so
In the year 1990 the mother was 40, and therefore double her daughters age, who was 20.

B.


y=kx, where k is the constant of proportionality
C.


y=kx, where k is the constant of proportionality
D.


y=xk, where y is the constant of proportionality

Answers

Answer:

Step-by-step explanation: The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

In a group of 27 pupils, 7 play the flute only.
5 play the piano only.
10 play both instruments.
A student is chosen at random.
What is the probability the student plays neither instrument?

Answers

Answer:

5/27

Step-by-step explanation:

I wrote it as a fraction, but the explanation is, if you're finding out how many who don't play instruments, you first need to find out who many do play instruments, so you add the numbers together.

10+5+7 = 22

So the probability that you'll pick one who does play an instrument would be 22/27 (because 22 out of the 27 pupils play an instrument.) But remember that's not what it's asking us for.

You have to subtract 27 - 22 to get the pupils who don't play instruments, you get 5, so the probability is 5/27 (5 pupils out of 27 don't play instruments.)

To put this in a percent, just divide the top number by the bottom number and move the decimal 2 places over, you get 18.5% or 19% both answers are correct depending on rounding.

Find the length of the missing side. The triangle is not drawn to scale

Answers

Answer:10

Step-by-step explanation:Use the Pythagorean theorem a^2 + b^2 = c^2, a is 8 and b is 6 so now you have 8^2 + 6^2 = C^2 this simplifies to 64 + 36 = c^2 those 2 numbers add up to 100 so C^2 is 100 then to get C you take the square root of 100 which is 10

The missing side 10.

Option C is the correct answer.

What is the Pythagorean theorem?

Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We can apply this theorem only in a right triangle.

Example:

The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.

Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm

We have,

Applying the Pythagorean theorem.

c² = 6² + 8²

c² = 36 + 64

c² = 100

c = √100

c = 10

Thus,

The missing side is 10.

Finally somebody asked whatthe problem was, and Lemon looked down at his hands and said that back in high school he'd had a couple of badexperiences with dentists. Real sadism, he said. Torture chamber stuff. He didn't mind blood or pain - he actually enjoyedcombat - but there was something about a dentist that just gave him the creeps. He glanced over at the field tent and said,"No way. Count me out. Nobody messes with these teeth.But a few minutes later, when the dentist called his name. Lemon stood up and walked into the tent.It was over fast. He fainted even before the man touched him.Four of us had to hoist him up and lay him on the cot. When he came to, there was a funny new look on his face, almostsheepish, as if he'd been caught committing some terrible crime. He wouldn't talk to anyone. For the rest of the day hestayed off by himself, sitting alone under a tree, just staring down at the field tent. He seemed a little dazed. Now and then wecould hear him cussing, bawling himself out. Anyone else would ve laughed it off, but for Curt Lemon it was too much. Theembarrassment must've turned a screw in his head. Late that night he crept down to the dental tent. He switched on aflashlight, woke up the young captain, and told him he had a monster toothache. A killer, he said - like a nail in his jaw. Thedentist couldn't find any problem, but Lemon kept insisting, so the man finally shrugged and shot in the Novocain and yankedout a perfectly good tooth. There was some pain, no doubt, but in the morning Curt Lemon was all smiles. By the end, Curt Lemon is characterized as: 1)Recklessly concerned with his reputation. 2)battle-hardened and powerful. 3)Overly impulsive but cheerful. 4)Childish and prone to fainting.
