LaShaundra is buying fence for two triangular sections of her garden.

mixas84 [53]

Answer: 80 feet.

Step-by-step explanation:

1. As you can see in the figure, triangle ABC and the triangle DFG are similar.

2. The scale of factor of triangle ABC to triangle DFG is the following:

$sf=\frac{20ft}{4ft}\\sf=5ft$

3. Therefore, the lenght of the side DG of the trinagle DFG is:

$DG=5*AC\\DG=5*7ft\\DG=35ft$

4. The perimeter of the triangle DFG is:

$P_{DFG}=20ft+25ft+35ft=80ft$

5. Therefore, she would need 80 feet of fence.

after hitting the black friday sales, sarah bought her dress on sale for $35. She saved 45%, what was the original cost.

8090 [49]

The original cost of the dress is $63.64

Step-by-step explanation:

After hitting the black Friday sales

Sarah bought her dress on sale for $35
She saved 45%

We need to find the original cost of the dress

The money that Sarah saved is the value of the discount on the dress

Assume that the price of the dress before the black Friday is 100%

∵ The price of the dress before the black Friday is 100%

∵ She saved 45% when she bought it the black Friday

∴ The price of the dress is decreased by 45%

∵ She bought the dress for $35 ⇒ (after discount)

Let use use the percentage method

→ Before discount : Discount : After discount

→ 100% : 45% : 55% (100 - 45)

→ x : : 35

By using cross multiplication

∵ x × 55% = 35 × 100%

- Divide both sides by 55%

∴ x = 63.64

The original cost of the dress is $63.64

MathUp Evaluating Expressions

AysviL [449]

Since the question is incomplete, answer will be subjective. An example of Evaluating Expressions is find h + 8 − 9 j − h; where h = 7 and j = 5.

<h3>What is the Evaluating Expressions?</h3>

The evaluating expressions is known to be a form of digital and printable board work that can help students in working on substituting values in terms of variables of an algebraic expression.

Evaluating the Expression below:

h + 8 − 9 j − h;

Therefore, where h = 7 and j = 5

7+ 8 − 9 (5) − 7.

SO: 7 + 8 - 45 -7

= -37

Therefore the answer to the Evaluating Expression is -37.
