John is performing an experiment in which a solution alternates between a clear color and a bluish-purple color at a regular time interval. He observes that the time interval between color changes is 30 seconds (s). Sally replicates the experiment with the same solution, but at a temperature that is 10 degrees Celsius (°C) higher. What is the most likely time interval between color changes at this higher temperature?
Answer:
15 seconds
Step-by-step explanation:
The given parameters for the experiment are;
The time it takes the solution to change from a clear color to a bluish-purple color at a given temperature = 30 seconds
The temperature at which Sally replicates the experiment with the same solution = 10°C higher than the temperature the experiment was carried out by John
Given that the process involves a change in color, which is a characteristic of a chemical reaction, and that the rate of a chemical reaction increases as the temperature of the reacting system is increased, we have time it takes for the solution to change color at a temperature increased by 10°C, will be a time lesser than 30 seconds

Help please
Answer:
x = 8/5
Step-by-step explanation:
first multiply both side by -1, it makes both side positive
1x/2 = 4/5
now multiply both sides by 2 to get the x by itself
x = 8/5
if they want improper fraction x = 1[tex]\frac{3}{5}[/tex]

PLEASE HELPPPP!! The options are
DC= AB
AC=AC
Answer:
the 1st one
Step-by-step explanation:
because A<C are the only angle ur missing.
Answer:
DC ≅ AB
Step-by-step explanation:
Because AC ≅ AC is given, I'm gonna assume its DC ≅ AB
I know kind of weird that I'm gonna have to assume when I've given 148 answers and I'm of the rank expert, however I looked at that triangle and all of those answers are correctly proving congruence, so it makes no sense to mark you wrong because technically ALL of the sides are given

solve nt+6-xt=s for t
Answer:
[tex]t=\frac{s-6}{n-x}[/tex]
Step-by-step explanation:
[tex]nt+6-xt=s[/tex]
[tex]\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}[/tex]
[tex]nt+6-xt-6=s-6[/tex]
[tex]Simplify[/tex]
[tex]nt-xt=s-6[/tex]
[tex]nt-xt[/tex]
[tex]=t\left(n-x\right)[/tex]
[tex]t\left(n-x\right)=s-6[/tex]
[tex]\frac{t\left(n-x\right)}{n-x}=\frac{s}{n-x}-\frac{6}{n-x};\quad \:x\ne \:n[/tex]
[tex]t=\frac{s-6}{n-x}[/tex]
Therefor the value of t after arrangement is t = (s-6)/(n-x)
What is Mathematical function ?
Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.
In other words the function represents the graph between x and y that is for each value of x there exist one value of y but here there is no restriction in values of y that is y can have infinity values.
Given equation is nt+6-xt=s
Now solving for t by separately variables and constant :
nt+6-xt=s
t(n-x) = s-6
t = (s-6)/(n-x)
Therefor the value of t after arrangement is t = (s-6)/(n-x)

If 15 pies will serve 20 people, how many pies are needed for 152 people?
Answer:
114 pies
Step-by-step explanation:
If the pie get together only had 20 people with 15 pies, then each person had a portion of 3/4 (divide them). The pie party has 152 people with 3/4 portions each, which means there has to be 114 pies at the party (multiply them).
:)
Answer:
152÷20=7.6
7.6×15=114
114 pies

Answer:
2/5 or .4
Step-by-step explanation:
basically look at the points where the line meets the graph. two points would be 0,20 and 50,40. then count the amount that it changes vertically and then horizontally. +20vertical +50 horizonal giving the slope 20/50. this can then be simplified to 2/5 or the equivalent number .4
Answer:
If I remember correctly, the slope would be 2/5.
Cary is having a party and can only afford to spend no more than $40 on food. She wants to order at least 3 pizzas which cost $6 a pie, and at least 2 orders of wings that cost $8 per order. Select all the inequalities she would have to graph to determine how many pizzas and wings she could order. Let x stand for the number of pizzas and y stand for the number of wings.
y ≥ 2
x ≥ 3
3 x + 8 y ≤ 40
6 x + 8 y ≤ 40
x ≤ 3
y ≤ 2

Answer:
For example, if a car runs 44 km on 2 litres of petrol then we can use the unitary method to find out the kilometres it will cover on 1 litre of petrol. In other words, the method by which we find out the value of one unit and further use it to find the value of multiple units is known as the unitary method.
