Jacinta says that the product of a rational number and an irrational number is always irrational her claim is wrong.
What is a rational number?A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.
Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.
Given that Jacinta says that the product of a rational number and an irrational number is always irrational.
Her statement is incorrect because if 0 a rational number is multiplied with the π which is irrational then the result will be 0 which is rational.
Therefore, Jacinta's claim is wrong.

Rihanna planned a rectangular courtyard for a park and made a scale drawing using inches as the unit of measurement. She originally planned for the length of the actual courtyard to be 54 feet, but she decided to change it to 72 feet. If the length of the courtyard is 18 inches in her scale drawing, which statement about the change of scale is true?
One inch represented 1 foot in the first scale, but now 1 inch represents 4 feet in the second scale.
One inch represented 4 feet in the first scale, but now 1 inch represents 3 feet in the second scale.
One inch represented 54 feet in the first scale, but now 1 inch represents 72 feet in the second scale.
One inch represented 3 feet in the first scale, but now 1 inch now represents 4 feet in the second scale.

I need help on these two please!
Answer:
See below
Step-by-step explanation:
Question 1:
7p + 5c = p
7p = p - 5c
6p = -5c
[tex]c = -\frac{6}{5}p[/tex]
Question 2:
y = 19x + 19b
y - 19x = 19b
[tex]b = \frac{y-19x}{19}[/tex]

14. The first four is in the 4000th place and the second four is in the 400th place
15. When the same two digits are next to each other in a multi-digit number, it doesn't mean that they are both in the same place value spot. For example, the number of 4,456 has two fours in it. But the first four is in the 4000th place and the second is in the 400th place.

Which pairs of numbers are the same distance apart as 2.9 and 3.8? Select all that apply. A 0 and 0.8 B 0 and 0.9 C 1.0 and 1.9 D 1.8 and 2.9 E 1.9 and 2.8
Answer:
subtract 2.9 from 3.8 you get 0.9
subtract 1.0 from 1.9 you get 0.9
subtract 1.9 from 2.8 you get 0.9
subtract 1.8 from 2.9 you get 01.1
I would say that your answers are E, C, and B.
Answer:
B, C, and E
Step-by-step explanation:
If you subtract 2.9 from 3.8 you get 0.9 so if u apply that to B, C, and E, you could add 0.9 to 0, 1.0, and 1.9 and get the equations:
0+0.9= 0.9
1.0+0.9= 1.9
1.9+0.9= 2.8
so as you can see it all just increases by 0.9 every time.
Punch recipe Ginger Ale 40% Orange Juice 25% Pineapple juice 20% Sorbet 15% Question 1: If you have 3 cups of pineapple juice, how many total cups of punch can you make? Question 2: Elise does not like sorbet, so she omits that ingredient and adds 5 percent of each of the other ingredients. How many cups of punch will she have if she uses 6 cups of orange juice?
Answer:
Question 1: 15 cups
20% (pineapple juice) = 3 cups, 100/20=5, 5*3 = 15 cups
Question 2: 20 cups
25% (orange juice) + 5% = 30%
30% (orange juice) = 6 cups, 30/6=5%, 100/5=20

Simplify the equation -(m+3n-12)
Answer:
-m - 3n + 12
Step-by-step explanation:
Because we don't know the values of "m" and "n" the simplest form you can get the equation to be is -m + - 3n + 12
That is because with a negative in front of the parenthesis it's like multiplying by negative 1. So -1 x m, -1 x 3n, and -1 x -12.

Some On PLEASE help me understand!!! Find f(4). Put your final answer in function form! f(x)=3x+5 g(x) = 2x^2-4 h(x) = -3x-9
Answer:
f(4) = 17Step-by-step explanation:
Given function f(x), when you want to find f(4) you just put 4 for every x in the equation of the function.
f(x) = 3x + 5 ⇒ f(4) = 3(4) + 5 = 12 + 5 = 17
g(x) = 2x² - 4 ⇒ g(4) = 2(4)² - 4 = 2•16 - 4 = 32 - 4 = 28
h(x) = -3x - 9 ⇒ h(4) = -3(4) - 9 = -12 - 9 = -21
