Geoff earns 10% commission on his total sales at work..To pay for a concert ticket, Geoff needs to earn $135 in commission. What must Geoff's sales total for the week?
Answer:
$1350
Step-by-step explanation:
Percentage commision earned = 10%
Amount needed to pay for concert = $135
Hence, total sales for the week must be :
Let total sales = x
10% of total sales = $135
10/ 100 * x = $135
0.1x = $135
x = $135 / 0.1
x = $1350
The first reaction will be a reaction of the iodide ion (I-1) with hydrogen peroxide (H2O2) in an acidic solution. This reaction produces a slightly orange solution. In our experiment, we will add some orange food coloring to make this solution more orange.
2 H+ (aq) + 2 I- (aq) + H2O2 (aq) ⟶ I2 (aq) + 2 H2O (l)
The next reaction will be between the iodine and starch
I2 + starch ⟶ I2-starch complex (blue-black)
So, when starch is added to the iodine solution made from the first reaction, the solution will turn black immediately, so it is difficult to find the rate of reaction. In order to be able to time this reaction, you will slow it down with another reaction. Adding ascorbic acid will react with the iodine, reducing the concentration of the iodine available to react with the starch.
C6H8O6 (aq) + I2 (aq) ⟶ 2I- (aq) + C6H6O6 (aq) + 2 H+ (aq)
When the ascorbic acid is used up, the remaining iodine molecules can react with the starch and form the black color. The more ascorbic acid you add, the slower the reaction to form the iodine-starch complex will be.
1. What was your hypothesis?
2. Plot your data as drops of ascorbic acid vs. time.
3. As the concentration of ascorbic acid was increased, did the rate of the formation of the iodine-starch complex increase or decrease? Explain your answer in terms of the chemical reactions involved.
4. Was your hypothesis correct?
5. Make a general rule about the effects of concentration of reactants on reaction rates.
6. For practice, the molecular formula for ascorbic acid is C6H8O6, and you used 6 g in this experiment, calculate the molarity of the ascorbic acid. Now calculate the concentration in moles per drop (assume 1 mL = 20 drops).
Answer:
hello ! i just did this project and received a 100,, so here you are ::
1. I hypothesize that if you continue to add more drops, then the time it takes will continue to increase.
2. A; 9.70 secs, B; 14.63 secs, C; 18.78 secs, D; 28.70 secs, E; 31.45 secs.
3. The formation continued to increased. As more was added, the time it took to reach the full reaction was increased.
4. Yes.
5. When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.
6. 6mL.
Step-by-step explanation:
for this one it was simple, they are only asking you what you think will happen to the time if they increase the number of drops. remember to use the "if....then..." format.i recorded the container labeled and the time it took for the solution to turn black. they are asking the same thing that they are for the hypothesis but this time after watching the video you know what actually happens. in this case, the more drops you put in the longer it takes for it to react. write this one down without the if then format.for mine, i got it correct but you can put yours wrong on purpose if youd like.i looked this one up, but it makes sense. this is correct, so dont worry.like i said,, i go this correct so dw ! <3
The rate of reaction depends on the slow step of a reaction.
A hypothesis is a tentative explanation of an observation. This question refers to an experiment so I will try to explain as much as possible. We can see that the rate of reaction is determined by the concentration of the ascorbic acid.
Hence, we can assert that, the more the concentration of the ascorbic acid, the lower the rate of reaction. The rate of reaction depends on the slow step of a reaction.
We know that the molar mass of ascorbic acid is 176 g/mol. The mass of ascorbic acid is 6 g. Hence;
Number of moles of ascorbic acid = 6 g/176 g/mol = 0.034 moles
concentration of ascorbic acid = 0.034 moles/20 × 1 × 10-3 = 1.7 M

My friends and I are sharing a candy bar. I got 1/4 of the candy bar, and my friend Abby got 1/4 of it. How much is left?

Step-by-step explanation:
Given: Fraction of candy bar I got = [tex]\dfrac14[/tex]
Fraction of candy bar friend got = [tex]\dfrac14[/tex]
Considering whole candy as 1.

Madison purchased 240 ft of fencing to build a corral for her horses. If each horse requires 600 ft2 of space, what is the maximum number of horses Madison can put in
the corral she builds with the fencing? Explain.
Answer:
6 horses
Step-by-step explanation:
2(x + y) ≤ 240
side lengths with greatest area = x = 120/2 and y = 120/2
60 × 60 = 3600ft²
3600/600 = 6 horses
Please Rate and Mark as Brainliest!
The required maximum number of horses is 7.
Given that,
Madison purchased 240 ft of fencing to build a corral for her horses. If each horse requires 600 ft2 of space, what is the maximum number of horses Madison can put in the corral she builds with the fencing is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Madison has 240 ft of fencing,
Circumference of corral = 240 ft
2πr = 240
r = 38.2
Now the area of the circular corral,
= πr²
= 4584.33
Now, the number of horses,
= total area of corral/area for each horse
= 4584.33 / 600
= 7.64
≈ 7
Thus, the required maximum number of horses is 7.

which range?
A. 9 minutes to 39 minutes
B. 19.25 minutes to 28.75 minutes
C. 14 minutes to 34 minutes
D. 19 minutes to 29 minutes
Answer:
C is the answer.
Step-by-step explanation:
i just got it right so that means you would too> let's goooo!!
The employees will have to travel within 19.25 minutes to 28.75 minutes.
What is Normal Distribution?'Normal distribution is a continuous probability distribution wherein values lie in a symmetrical fashion mostly situated around the mean.'
According to the given problem,
Mean time = 24 minutes
Standard deviation = 5 minutes
Therefore,
⇒24 + 5 = 29
⇒24 - 5 = 19
Now,
(29 - 19) * 95% = 9.5
Hence, we can conclude that 95% of the employees will have to travel within 19.25 minutes to 28.75 minutes.

Find the distance between Riverside and Milton if they are 15 cm apart on a map with a scale of 4 cm: 21 km.
pls answer i will give points
Answer:
66.9375
Step-by-step explanation:
from what you told me 4cm=21km
if you divide 21 by four, you get how many km is one cm. which is 5.25km
15 divided by 4 = 3.75
what we know is that 4 can go into 15 three whole times. so.. 21x3=63
now what we need to figure out is that .75
so, 75 is three quarters, so i divided 5.25 divided by 4 to get how much one quarter of a cm is in km. then i multipled that by three, giving me: 3.9375

O B. (4,4)
O C. (-16,4)
O D. (4.16)
Answer:
The coordinates of point D( 4,4)
Step-by-step explanation:
Step(i):-
Given points are E(10,4) and B(16,4)
'E' is the mid-point of segment BD
Let D(x₁, y₁) be a point
E = midpoint of segment BD
[tex](10,4) = (\frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )[/tex]
[tex]10 = \frac{x_{1} +16 }{2}[/tex]
20 = x₁ + 16
20-16 = x₁
x₁ =4
Step(ii):-
[tex]\frac{y_{1} +y_{2} }{2} = 4[/tex]
[tex]\frac{4 +y_{2} }{2} = 4[/tex]
4 + y₂ = 8

32 + 24 = 55 ( + ) Write 32 + 23 as a product of the two factors using the GCF and the distributive property.
The right presentation of the question is:
(a) Write 32 + 24 as a product of the two factors using the GCF and the distributive property.
(b) Write 32 + 23 as a product of the two factors using the GCF and the distributive property.
Answer:
[tex](a)\ 32 + 24 = 8*7[/tex]
[tex](b)\ 32 + 23 = 5*11[/tex]
Step-by-step explanation:
Solving (a):
First, we take the GCF of 32 and 24
[tex]32 = 2 * 2 * 2 * 2 * 2[/tex]
[tex]24 = 2 * 2 * 2 * 3[/tex]
Take common factors:
[tex]GCF = 2 * 2 * 2[/tex]
[tex]GCF = 8[/tex]
So, we factorize 32 and 24 using 8.
The expression becomes:
[tex]32 + 24 = 8(4 + 3)[/tex]
Simplify the expression in bracket
[tex]32 + 24 = 8(7)[/tex]
Remove bracket
[tex]32 + 24 = 8*7[/tex]
--------------------------------------------------------------------------------------------------
Solving (b):
[tex]32 + 23 =[/tex]
32 and 23 do not have a common factor, so we have to start by writing 32 as 30 + 2
[tex]32 + 23 = 30 + 2 + 23[/tex]
Add 2 to 23
[tex]32 + 23 = 30 + 25[/tex]
Take the GCF of 30 and 25
[tex]30 = 2 * 3 * 5[/tex]
[tex]25 = 5 * 5[/tex]
Take common factors:
[tex]GCF = 5[/tex]
So, we factorize 30 and 25 using 5.
[tex]32 + 23 = 5(6 + 5)[/tex]
Simplify the expression in bracket
[tex]32 + 23 = 5(11)[/tex]
Remove bracket
[tex]32 + 23 = 5*11[/tex]
