A student conducted an experiment to test whether talking to plants would help them to grow faster. He set up the following two groups: Group 1: spoken to and hand watered Group 2: not spoken to and hand watered After three weeks, the plants in Group 1 showed much more growth than those in Group 2.
Name the independent and dependent variable.
Answer: Group 1 is the dependent variable, and group 2 is the independent
Step-by-step explanation: The dependent variable is the variable that is being measured or tested in an experiment. So, Group 1 would be the dependent variable, because as it says the the group 1 plants were spoken to and hand watered as in they changed the outcome of the experiment.
The independent variable is the variable the experimenter changes or controls. So, the independent variable would be group 2 because the group 2 plants outcome was not determines anything but it's self.

Blanca earns a yearly salary of $55,000. Isabel earns a yearly salary of $63,000. Blanca will receive a salary increase of $3,700 per year, and Isabel will receive a salary increase of $2,900 per year.
Which equation can be used to find n, the number of years it will take Blanca to earn the same salary as Isabel?
55,000n + 3,700 = 63,000 + 2,900n
55,000n + 3,700n = 63,000n + 2,900n
55,000n + 3,700n = 63,000n + 2,900
55,000 + 3,700n = 63,000 + 2,900n
PLSS ANSWER ILL MAKE MOST BRAINLIEST!!!!
Answer:
last choice: 55,000 + 3,700n = 63,000 + 2,900n
Step-by-step explanation:
Blanca's salary now: 55,000
Adding $3,700 per year will add 3,700n in year n.
Her salary in year n will be 55,000 + 3,700n
Isabel's salary now: 63,000
Adding $2,900 per year will add 2,900n in year n.
Her salary in year n will be 63,000 + 2,900n
We set the two total salaries equal:
55,000 + 3,700n = 63,000 + 2,900n

Find the distance between the points (3,6) and (10,4). The answer must be a whole number or a fully simplified radical expression do not round up
Answer:
The answer is
[tex]\sqrt{53} \: \: \: units[/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3,6) and (10,4).
The distance is
[tex]d = \sqrt{ ({3 - 10})^{2} + ({6 - 4})^{2} } \\ = \sqrt{ ({ - 7})^{2} + {2}^{2} } \\ = \sqrt{49 + 4} \\ = \sqrt{53} \: \: \: \: \: \: \: \: [/tex]We have the final answer as

Find the real roots of
[tex] \frac{18}{ {x}^{4} } + \frac{1}{ {x}^{2} } = 4[/tex]
see the photos above given
Answer:
[tex]$x^2=\frac{9}{4} \implies x=\pm \frac{3}{2} $[/tex]
[tex]$x^2=-2 \implies x=\pm\sqrt{-2} \implies x=\pm\sqrt{2i} $[/tex]
The solutions are
[tex]$\{-\frac{3}{2},\frac{3}{2}, -\sqrt{2i}, \sqrt{2i} \}$[/tex]
The Real roots are
[tex]$\{-\frac{3}{2},\frac{3}{2}\}$[/tex]
Step-by-step explanation:
[tex]$\frac{18}{x^4} +\frac{1}{x^2}=4$[/tex]
Multiply both sides by [tex]x^4[/tex]
[tex]$x^4\frac{18}{x^4} +x^4\frac{1}{x^2}=4\cdot x^4$[/tex]
[tex]$18+x^2=4x^4$[/tex]
[tex]4x^4-x^2-18=0[/tex]
Substitute [tex]x^2=t[/tex]
[tex]4t^2-t-18=0[/tex]
Solving the quadratic equation using the quadratic formula:
[tex]$t=\frac{-(-1)\pm \sqrt{(-1)^2-4\cdot 4(-18)}}{2\cdot 4}$[/tex]
[tex]$t=\frac{1\pm \sqrt{289}}{8}$[/tex]
[tex]$t=\frac{1\pm 17}{8}$[/tex]
[tex]$t_1=\frac{9}{4}$[/tex]
[tex]t_2=-2[/tex]
Now we have to solve for [tex]x^2=t[/tex]
[tex]$x^2=\frac{9}{4} \implies x=\pm \frac{3}{2} $[/tex]
[tex]$x^2=-2 \implies x=\pm\sqrt{-2} \implies x=\pm\sqrt{2i} $[/tex]
The dashed triangle is a dilation image of the solid triangle. What is the scale factor? A. 1/4 B. 1/2 C. 2/3 D. 2
Answer:
I am not good in maths but I think it is
A 1/4
A model's scale ratio is the ratio of linear dimensions. The scale factor of the triangle is (1/2).
What is the scale ratio?A model's scale ratio is the proportionate ratio of a linear dimension of the model to the equivalent characteristic of the original.
The scale ratio of the triangle can be found by taking the ratio of any one side of the dashed triangle to the solid triangle. Therefore, the scale ratio will be,
[tex]\rm Scale\ ratio = \dfrac{\text{Length of the dashed line}}{\text{Length of the solid line}}\\\\ Scale\ ratio = \dfrac{2}{4} = \dfrac{1}{2}[/tex]
Hence, the scale factor of the triangle is (1/2).

Answer:
292 lines of code
Step-by-step explanation:
1.) Multiply. 25 times 5 = 125
2.) Multiply previous answer by 2 (because he wrote twice as much). 125 times 2 = 250

14 – (2y + 5) = -2y + 9
Answer:
The answer is all real numbers
Step-by-step explanation:
Simpify both sides of the equation: 14−(2y+5)=−2y+9
14+−1(2y+5)=−2y+9(Distribute the Negative Sign)
14+−1(2y)+(−1)(5)=−2y+9
14+−2y+−5=−2y+9
(−2y)+(14+−5)=−2y+9(Combine Like Terms)
−2y+9=−2y+9
−2y+9=−2y+9
Then add 2y to each side. −2y+9+2y=−2y+9+2y
9=9. Then subtract 9 from each side. 9-9=9-9=0. That means that all real numbers is the answer.
Hey there!
[tex]Answer:\boxed{\text{All are solutions}}[/tex]
[tex]Explanation:[/tex]
[tex]14-(2y+5)=-2y+9[/tex] Equation
14−(2y+5)=−2y+9 Simplify both sides
14 + -1(2y + 5) = −2y + 9 Distribute Negative
14 + -1(2y) + (-1)(5) = -2y + 9
14 + −2y + −5 = −2y + 9
(−2y) + (14 + −5) = −2y + 9 Combine the like terms
−2y + 9 = −2y + 9
-2y + 9 + 2y = -2y + 9 + 2y Add 2y to both sides
9 = 9
9 - 9 = 9 - 9 Subtract 9 from both sides
0 = 0
All are solutions.

Order 5/8 , 0.5 , 58.3% greatest to least
Answer:
0.5,5/8, 58.3
Step-by-step explanation:
0.5 is 1/2, and 5/8 is 1/8th larger than 1 half, and 58.3 is the only one with a whole number, so its the largest. Hope this helped, can i maybe get brainliest :D
The required ascending order is given as 0.5, 58.3%, and 5/8.
Given that,
To arrange the given number in ascending order,
5/8 , 0.5 , 58.3%
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
5 / 8 = 0.625
58.3% = 0.583
So,
0.5 < 58.3% < 5/8
Thus,the required ascending order is given as 0.5, 58.3%, and 5/8.

Train A and train B stops at Swindon at 10:30 . Train A stops every twelve minutes and train B stops every 14 Mins , when do they both stop at Swindon again ?
Answer: at 11:54
Step-by-step explanation:
Let's define the 10:30 as our t = 0 min.
We know that Train A stops every 12 mins, and Train B stops every 14 mins, they will stop at the same time in the least common multiple of 12 and 14.
To find the least common multiple of two numbers, we must do:
LCM(a,b) = a*b/GCD(a,b)
Where GCD(a, b) is the greatest common divisor of a and b.
In this case the only common divisior of 12 and 14 is 2.
So we have:
LCM(12, 14) = 12*14/2 = 84.
Then the both trains will stop 84 minutes after 10:30
one hour has 60 mins, so we can write 84 minutes as:
1 hour and 24 minutes = 1:24
Then they will stop at the same time at 10:30 + 1:24 = 11:54

Step-by-step explanation:
The midpoint of the line ST lies on the x-axis with the coordinate, (-3, 0)
What is a midpoint?A midpoint is the center of two points, It lies at the same distance from the two endpoints.
The coordinates of the endpoints of a line ST are as follows:
The coordinate of S is (-6, -1)
The coordinate of T is ( 0, 1)
The midpoint of the line ST is M
The coordinates of M is given as,
M = ( x₁ + x₂) /2 , ( y₁ + y₂) /2
