A rectangle has perimeter 200 feet.
1. Let L represent the length of the rectangle. Write an equation for the width W in terms of L.
2. Write a function A(L) that represents the area of the rectangle with length L.​

Answers

Answer:1. (200-2L)/2      2.L x (200-2L)/2=A

Step-by-step explanation:

Answer:

Part 1)

[tex]W=100-L[/tex]

Part 2)

[tex]A(L)=L(100-L)[/tex]

Step-by-step[tex]W = 100-L[/tex] explanation:

We are given a rectangle with a perimeter of 200 feet.

Part 1)

The formula for perimeter for a rectangle is:

[tex]200=2(L+W)[/tex]

We can divide both sides by 2:

[tex]100=L+W[/tex]

And subtracting L from both sides yields:

[tex]W=100-L[/tex]

Part 2)

The area of a rectangle is given by:

[tex]A(L)=LW[/tex]

Since we solved for W earlier:

[tex]A(L)=L(100-L)[/tex]

Solve the inequality for x.


x-c/d > y (for d > 0)

Answers

The solution for x of the inequality x-c/d > y (for d > 0) is x > d * y + c.

Here,

To solve the inequality for x, we'll isolate x on one side of the inequality:

Given inequality: (x - c) / d > y

First, we'll multiply both sides of the inequality by d to get rid of the fraction.

Remember that since d > 0, we don't need to reverse the inequality:

d * [(x - c) / d] > d * y

Next, the d on the left side cancels out, and we have:

x - c > d * y

Now, to isolate x, we'll add c to both sides of the inequality:

x - c + c > d * y + c

x > d * y + c

So the solution for x is x > d * y + c.

Emilia and Sydney went out to dinner. The bill came to $48. They want to leave a 20% tip and
split the bill. How much do they each pay?
$9.60
$28.80
$57.60
$68.00

Answers

Answer:

Option B is correct.

Step-by-step explanation:

Total bill = $48

Tip = 20%

Amount of tip = 20% of 48

Amount = [tex]\frac{20}{100}*48[/tex]

Amount = 0.2 * 48

Amount = $9.60

Total bill with tip = 48 + 9.60 = $57.60

Dividing by 2 as they are spliting the bill.

Each pays = [tex]\frac{57.60}{2}=28.80[/tex]

Therefore,

Option B is correct.

5 divided 9/10 in fractions forms

Answers

Answer: 5 5/9

Step-by-step explanation:

cause that’s the answer

5 divided by 9/10, in fraction form, is 50/9.

To divide 5 by 9/10, we can convert the whole number 5 into a fraction with a denominator of 1.

5 can be expressed as 5/1.

We can rewrite the division problem as a multiplication problem by taking the reciprocal (flipping the numerator and denominator) of the divisor:

5/1 ÷ 9/10

= 5/1 × 10/9

Multiply the numerators together and the denominators together:

(5×10) / (1 × 9) = 50/9

Therefore, 5 divided by 9/10, in fraction form, is 50/9.
