How does the percent equation relate proportional quantities?​

Answers

Answer 1

Answer: Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.

y=-2x+10
3y-x+5=0
Solve the system using substitution

Answers

The first equation is already solved for y. So we can plug that into the second equation.

3y - x + 5 = 0
3(-2x + 10) - x + 5 = 0

Distribute the 3
-6x + 30 - x + 5 = 0

Combine like terms
-6x - x + 30 + 5 = 0
-7x + 35 = 0

Subtract 35
-7x = -35

Divide by -7
x = 5

Plug x into either equation to solve for y
y = -2x + 10
y = -2(5) + 10
y = -10 + 10
y = 0

A group of friends wants to go to the amusement park. They have no more than $235 to spend on parking and admission. Parking is $7, and tickets cost $28.50 per person, including tax. Write and solve an inequality which can be used to determine pp, the number of people who can go to the amusement park.

Answers

228/28.50= 8 that should be right!

The solution of the inequality for the number of people (p) who can go to the amusement park will be;

⇒ p < 8

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

They have no more than $235 to spend on parking and admission.

And, Parking is $7, and tickets cost $28.50 per person, including tax.

Now,

Let the number of people who can go to the amusement park = p

So, We can formulate;

⇒ 28.50p + 7 < 235

Solve for p as;

⇒ 28.50p < 235 - 7

⇒ 28.50p < 228

⇒ p < 228/28.50

⇒ p < 8

Thus, The solution of the inequality for the number of people (p) who can go to the amusement park is;

⇒ p < 8

Henry buys a softball for $16 plus a 9% tax. Ella buys a pair of shoes for $17 plus a 9% tax. Enter the difference in the
amount Henry and Ella paid, including tax. Round your answer to the nearest cent.​

Answers

Answer:

$1.09

Step-by-step explanation:

Henry: 16 increase 9% =

16 × (1 + 9%) = 16 × (1 + 0.09) = 17.44

Ella: 17 increase 9% =

17 × (1 + 9%) = 17 × (1 + 0.09) = 18.53

Difference: 18.53 - 17.44 = 1.09

find the measure of each angle indicated and please explain how you got that answer if you can ​

Answers

#15- The answer should be 35.
In the photo I included, both points A and B are equal, because they are intersecting. To get the measurement for these angles, you add 40+40 to get 80. We know that three angles in a triangle need to add up to 180, so you would subtract 80 to get 100. If point A and B are 100, that means you can add 100+45 to get 145, and subtract that from 180 to get your answer. (35)

#16- The answer should be 42. Using the same logic as before, take away 80+40 from 180 to get 60 for points A and B. Then you would subtract 78+60 from 180 to get your answer. (42)

#17- The answer should be 108. You need to find the final angle of the triangle by subtracting 37+71 from 180. This would equal 72. Since the angle of a line is 180 degrees, you would subtract 72 from 180 to get the finished product. (108)

#18- The answer should be 35. You would start by finding the bottom left angle. You would use the same logic as I did in #17 by subtracting 180-126. This tells you that the bottom left angle in the triangle is 54. Then you would subtract 91+54 from 180 to get your answer. (35)

I hope this helps and that it wasn’t too confusing. #17 and #18 aren’t my strong suit, so I’m sorry if I’m wrong. Please mark brainliest!

find the least common denominator and write the equivalent fractions 1/6 and 1/9​

Answers

Answer:

1/6 - least common - 3/18

1/9 - least common - 2/18

3/18 is equivalent to 1/6

1/9 is equivalent to 2/18

Step-by-step explanation:

Rewriting input as fractions if necessary:

1/6, 1/9

For the denominators (6, 9) the least common multiple (LCM) is 18.

LCM(6, 9)

Therefore, the least common denominator (LCD) is 18.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/6   =   1/6   ×   3/3  =   3/18

1/9   =   1/9   ×   2/2  =   2/18

Answer:

The LCD is 18. The equivalent fractions are 1/6 = 3/18 and 1/9 = 2/18. Hope this helps :)

Answer:

When a problem has infinite solutions, you'll end up with a statement that's true no matter what. For example: 3=3 This is true because we know 3 equals 3, and there's no variable in sight. Therefore we can conclude that the problem has infinite solutions. You can solve this as you would any other question.
