point k lies at (-3,4) Image

Answers

Answer:

[tex]k(x,y) --> k'(x,y-7)[/tex]

Step-by-step explanation:

Given

[tex]k = (-3,4)[/tex]

Translation: 7 units down

Required

Determine the rule to produce k'

When an (x,y) coordinate is translated down by h units, the resulting point is:

(x,y) --> (x, y - h)

In this case:

[tex]h = 7[/tex]

So, we have:

[tex]k(x,y) --> k'(x,y-7)[/tex]

Hence, option A answers the question.

Solving further to determine the coordinates of k'.

[tex]k = (-3,4)[/tex]

[tex]k' = (-3,4-7)[/tex]

[tex]k' = (-3,-3)[/tex]

4/5 of Peter's money is twice as much as Weimin's money. What fraction of Peter's money is Weinim's money?

Answers

Answer:  [tex]\dfrac25[/tex]

Step-by-step explanation:

As per given,

[tex]\dfrac45\times(\text{Peter's money})=2 (\text{Weimin's money})[/tex]

Let x= Weimin's money

Then [tex]\dfrac45\times(\text{Peter's money})=2x[/tex]

[tex]\text{Peter's money}=2x\times\dfrac54\\\\\Rightarrow\ \text{Peter's money}=\dfrac52x[/tex]

The required fraction= [tex]\dfrac{\text{Weinim's money}}{\text{Peter's money}}[/tex]

[tex]=\dfrac{x}{\dfrac{5}{2}x}=\dfrac{1}{\dfrac52}\\\\\\=\dfrac25[/tex]

Hence, Required fraction = [tex]\dfrac25[/tex]

The lengths of the sides of a triangle are in the extended ratio 4:7:10. The perimeter of the triangle is 105 cm. What are the lengths of the sides?
The lengths of the sides of the triangle in cm are

Answers

Answer:

20cm, 28cm, 40cm

Step-by-step explanation:

Let the shortest side be 4x, the middle side be 7x and the longest side be 10x.

4x + 7x + 10x = 105

21x = 105

x = 105 ÷ 21

x = 5

Shortest side (4x) = 5 × 4

Shortest side (4x) = 20

Middle side (7x) = 7 × 4

Middle side (7x) = 28

Longest side (10x) = 10 × 4

Longest side (10x) = 40

Her first jump is 4.25 m.
Her best jump is 12% more than this.
However, her best jump is 15% lower than the winning jump.
Work out the length of the winning jump.

Answers

Ok so her best jump equation would be
4.25x 1.12 = 4.76
Sarahs best jump = 4.76
The equation for the winning jump would be
4.76x 1.15 = 5.474
The winning jump would be = 5.474

Amelia is deciding between two landscaping companies for her place of business.
Company A charges $35 per hour and a $250 equipment fee. Company B charges $25
per hour and a $300 equipment fee. Let A represent the amount Company A would
charge for t hours of landscaping, and let B represent the amount Company B would
charge for t hours of landscaping. Write an equation for each situation, in terms oft,
and determine which company would be cheaper if Amelia needs 7 hours of
landscaping.

Answers

Answer: B is Cheaper

Step-by-step explanation: Pic is attached. It is the initial price plus the money they charge per hour, multiplied by hour. From there it is just plugging in 7 for the hour. Hope this helps!

Company B would be cheaper than Company A for 7 hours of landscaping.

What is an equation?

Two or more expressions with an equal sign are defined as an equation.

Given that, Company charges $35 per hour and a $250 equipment fee while Company B charges $25 per hour and a $300 equipment fee.

The amount charged by Company A for t hours of landscaping is:

A = 35t + 250      (1)

Similarly, the amount charged by Company B for t hours of landscaping is:

B = 25t + 300      (2)

Now, solve equation (1) for t = 7:

A = 35 (7) + 250

A = 245 + 250

A = 495

Hence, company A would charge $495 for 7 hours of landscaping.

Similarly, solving equation (2) for t = 7:

B = 25(7) + 300

B = 175 + 300

B = 475

Hence, company B would charge $475 for 7 hours of landscaping.

Therefore, Company B would be cheaper than Company A for 7 hours of landscaping.
