Laura buys a saddle in the UK for £850 Delivery is free. Steve buys the same saddle from Holland for 990 Euros. He pays 15 Euros for delivery. £1 = 1.18 Euros Including the delivery charge, whose saddle is cheaper?

Answers

Answer:

Laura's saddle is cheaper

Step-by-step explanation:

We want to convert from euros to pound and compare which purchase is more expensive.

given data

we are told that Steve buys the same saddle from Holland for 990 Euros

given the exchange rate in pounds, it will be

£1 = 1.18 Euros

 x=990 Euros

cross multiply we have

x=990/1.18

x= £838.98

Steve buys at  £838.98

delivery charge is  15 Euros to pounds

£1 = 1.18 Euros

 x=15 Euros

cross multiply we have

x=15/1.18

x= £13.04

to expenses incurred by Steve= £838.98+£13.04

=£852.02

Laura's saddle is cheaper

loren wants to buy a golf club that is $98 today it is on sale for 25% off how much is the discount and what is the sale price

Answers

98 x .25 = discount so 24.5
then 98 - 24.5 = 73.5 for sale

The discount is $24.5 and Sale Price is $122.5.

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

loren wants to buy a golf club that is $98.

Sale= 25% off

So, the discount is

= 98 x 25/100

= 98 x 1/4

= $ 24.5

and, the Sale Price is

= 98 + 24.5

= $122.5.

Just look at the picture lol.....The equations of three lines are given below.

Line 1 and Line 2: Parallel O Perpendicular O Neither Х Line 1 and Line 3: O Parallel O Perpendicular O Neither Line 2 and Line 3: Parallel O Perpendicular Neither​

Answers

Answer:

Step-by-step explanation:

We will use the following steps to solve this problem,

Step - (1).

Covert the equations into slope-intercept form.

Step - (2)

If the slopes of the two lines are equal, lines will be parallel.

[tex]m_1=m_2[/tex]

Step - (3)

If the slopes of the two lines are negative reciprocal, lines will be perpendicular.

[tex]m_1\times m_2=-1[/tex]

Line 1: 8x - 6y = -2

          6y = 8x +2

            y = [tex]\frac{4}{3}x+\frac{1}{3}[/tex]

Slope of line 1 = [tex]m_1=\frac{4}{3}[/tex]

Line 2: y = [tex]-\frac{3}{4}x-5[/tex]

Slope of line 2 = [tex]m_2=-\frac{3}{4}[/tex]

Line 3: 4y = -3x + 3

             y = [tex]-\frac{3}{4}x+\frac{3}{4}[/tex]

Slope of line 3 = [tex]m_3=-\frac{3}{4}[/tex]

1). Since, [tex]m_1\times m_2=\frac{4}{3}\times (-\frac{3}{4})=-1[/tex]

   Line 1 and line 2 are perpendicular.

2). Since, [tex]m_1\times m_3=\frac{4}{3}\times (-\frac{3}{4})=-1[/tex]

   Line 1 and line 2 are perpendicular.

3). Since, [tex]m_2=m_3=-\frac{3}{4}[/tex]

   Line 2 and line 3 are parallel.

Answers

Answer: (6,1)

Step-by-step explanation:

A point which lies on the graph of the finite sequence is,

⇒ (6, 1)

Given that;

A sequence is,

⇒ 5, -1, 6, 0, 7, 1, 8

Now, You have to look at the first coordinate (x -Axis) then go over that many times in the sequence and if that number is matched with the y-axis, then you got it.

Hence, Look at your numbers then go to (6, 1) go over 6 and if you land on 1 then that's the answer.
