Step-by-step explanation:

The sale price of a bike after being discounted 20% is $213.20. Which equation can you use to find the original cost of the bike b?​

213.2 : 80 = x : 100

x = 213.2 * 100 : 80

x = 266.5

Determine if the given ordered pair, (1,−2), satisfies the given equation
yes or no

Answers

Answer:

(1, - 2 ) is a solution

Step-by-step explanation:

Substitute the coordinates into the left side and if equal to the right side then the ordered pair is a solution.

5(1) + 4(- 2) = 5 + (- 8) = 5 - 8 = - 3 = right- side

Then (1, - 2 ) is a solution of the equation

Work out the length x. 14cm, 7cm , right angle triangle

Answers

The given triangle is a right angled triangle. So we can use the pythagorean theorem to solve this.

Hypotenuse = 14 cm

Altitude = 7 cm

Base = x cm

Using pythagorean theorem,

Hypotenuse² = Base² + Altitude²

14² = x² + 7²

14² - 7² = x²

196 - 49 = x²

147 = x²

√147 = x

12.124 = x (approx.)

we have a 1in : 0.2in scale of drawing to reality.

0.2 = 2/10 = 1/5

so, 1in in the drawing is actually 1/5in in reality.

how long are the 4in in the drawing ?

well, 4 times the 1in thing.

4×1/5 = 4/5 = 0.8in long

again the similar triangles

similar triangles means that each pair of corresponding lines (sides, heights, ...) in the triangles follows the same scaling factor for the length.

so, what do I need to multiply the side of the large triangle with to get the corresponding side length of the small triangle ?

27 × x = 9

x = 9/27 = 1/3

and that is the scale factor.

What is a History museum?

Museums and galleries generally provide insight into human history. The lessons we may learn from historical occurrences, wonders, and tragedies are inestimably important, even though no museum claims to provide a complete picture. This is especially true when things are tumultuous.

In the interest of society, a museum investigates, gathers, conserves, interprets, and presents both tangible and intangible history. Through accessibility, inclusivity, and public accessibility, museums promote diversity and sustainability.

Thus, The bus fare is more expensive now than it was the last time I was here. Excuse me, does the ticket machine give change? Excuse me, does the ticket machine give change? There is a taxi rank right outside the train station. What time do you want me to pick you up from the station? We have to  check in at the airport two hours before the plane leaves.

SOMEONE PLEASE HELPPPPPP MEEEEE

Answers

Answer:

carlas had the better deal

Step-by-step explanation:

if you buy an suitcase at $85 with 20% discount, you will pay 85 - 17 = 68 dollars.

if you buy an suitcase at $75 with 15% discount, you will pay 75 - 11.25 = 63.75

divide 20% by a 100 =0.2 than times 0.2 by $85 which will equal 17 subtract 17 from $85

do the same for the second one.

common difference = 625 - 628 = -3         common difference = 449-436 = 13

we can continue series like this              

613 - 3 = 610                            [2011]             501 + 13 = 514

610 - 3 = 607                           [2012]            514 + 13 = 527

607 - 3 = 604                          [2013]             527 + 13 = 540

604 - 3 = 601                           [2014]             540 + 13 = 553

601 - 3 = 598                           [2015]             553  + 13 = 566

598 - 3 = 595                          [2016]             566 + 13 = 579

595 - 3 = 592                          [2017]              579 + 13 = 592
