Answer:
$45 after the discount
Step-by-step explanation:
Set up a proportion.
[tex]\frac{x}{50} = \frac{10}{100}[/tex] $50 is the total amount and make the 10% a decimal
x(100) = 50(10)
100 = 500
100 ÷ 500
x = 5 <-- We have to subtract this amount from the total
$50 - $5 = $45 <-- total after the discount
Hope this helps!!

You roll 2 fair 6-sided dice. What is the probability of rolling a sum of 7 or more?
18/36 or 1/2
20/36 or 5/9
19/39
21/36 or 7/12
Answer:
here we have rolled two dice. So total no. of possible outcomes will be 6^2=36. These are (1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).
Now, among these cases the cases where the sum is seven for (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) i.e. there are 6 cases.
Now, it is time to calculate the probability.
The required probability is,
p = (No. of cases favorable for the event)/(Total no. of cases)
=6/36 =

10. SALES Jhan bought an 8-ounce fruit drink for
$1.50. Write and solve a proportion that could
be used to find the cost of a gallon of fruit
drink. (Hint: 1 gal = 128 oz)
Answer:
8/1.50 = 128/x
Step-by-step explanation:
In this case, I put the amount of fruit drink over the cost!
8 ounces/$1.50
there are 128 ounces in a gallon and we want to find out the cost of a gallon, so we can put that as x!
128 ounces/x
There's your proportion! Hope this helps :)

In a sports meet, Sonam's team completes the run at 40 seconds during heat events. On championship day, his team completes the same run at 45 seconds. What is the percentage difference in the completion time from the best completion time? A. 10.5% B. 12.5 % C. 15.5 % D. 20.5 %
Answer: B. 12.5 %
Step-by-step explanation:
GIven: Best completion time = 40 seconds
completion time of other members = 45 seconds
The percentage difference in the completion time from the best completion time = [tex]\dfrac{difference}{Best\ completeion\ time}\times100[/tex]
[tex]=\dfrac{45-40}{40}\times100\%\\=\dfrac{5}{40}\times100\%\\\\=12.5\%[/tex]
Hence, the correct option is B. 12.5%.
The percentage difference in the completion time from the best completion time is 12.5%.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is that Sonam's team completes the run at 40 seconds during heat events while on the championship day, his team completes the same run at 45 seconds. Therefore, the difference can be written as,
[tex]\rm Difference =45\ sec -40\ sec=5\ sec[/tex]
Now, as we want to know the percentage difference in the completion time from the best completion time, therefore, we can write,
[tex]\text{Percentage Difference}=\dfrac{\text{Difference}}{\text{Best completion time}} \times 100[/tex]
[tex]=\dfrac{5}{40}\times 100\\\\=12.5\%[/tex]
Hence, the percentage difference in the completion time from the best completion time is 12.5%.

Answer:

Step-by-step explanation:
Why do we need complex numbers, what are conjugates, and why do we need them
I guess I can give a brief overview and then you can decide if I should go deeper into these meaning and use.
Complex numbers are useful because in a lot of cases we need to use the square root of a negative number. Ex.
Solve the quadratic equation x^2+x+1=0
We have to use the quadratic formula since its not factorable.
x=[-1+-sqrt(1-4*1*1)]/2
x=-1/2 + or - sqrt(-3)
If we don't have imaginary numbers, we would be stuck because sqrt(-3) wouldn't exist as you cannot take the square root of a negative number.
But with complex numbers we can actually get the answer for that equation as
x=-1/2 + or - sqrt3*i
Which would give us a mean of using this answer to calculate further to get other needs depending on the problem you are solving. If complex number is not a thing, about half of our equations will have undefined answers.
Now conjugates is a more interesting one, on the surface level we are discussing here there is not much its used for except if you have a complex number as a root of a quadratic equation, then the conjugate of that complex number must also be a solution. Again if you want me to go a more in depth just comment down below, because I could write an entire essay on this topic :-)
write the equation for the inverse of the function y=pi/4+sinx
Answer:
Step-by-step explanation:
Sine doesn't have an inverse, until you restrict the domain to -pi/2 to pi/2. If you don't restrict the domain, then the inverse doesn't exist. Im going to assume the domain is restricted.
Switch the x and y values
[tex]x= \pi/4+ \sin(y)[/tex]
Subtract pi/4 on both sides
[tex]x- \pi/4= \sin(y)[/tex]
Take the arcsine of both sides
[tex]\arcsin(x- \pi/4)=y[/tex]

Solve using the substitution method
x = 8y - 4
x + 8y = 6
i will give brainliest and pls show work
You are told x = 8y -4
Replace x in the second equation with 8y-4:
8y-4 + 8y = 6
Combine like terms:
16y-4 = 6
Add 4 to both sides:
16y = 10
Divide both sides by 16:
Y = 10/16
Simplify:
Y = 5/8
Now replace y with 5/8 do find x:
X = 8(5/8) -4 = 5-4 = 1
X = 1, y = 5/8
(1,5/8)

Answer:
for the first one : 0.91 or 0.916 either one
for the second answer : 1 11/20
Step-by-step explanation:
Here is the explanation for the second question>>>To find the total of 3/4 and 4/5 is to add them together. However, in order to add them together you need to find the least common denominator (LCD). And the LCD of both denominators would be 20, because that is the smallest number both 4 and 5 can divide into. And here is the tricky part, now you have to change the numerators. So since 3/4th's now has a denominator of 20 you have to make the 3 match the 20. So 4 times what it 20? It is 5. So now multiply 5 by three and that will give you 15/20, which can reduce to 3/4 which means that you did this correctly! Now repeat the same steps with 4/5:
4/5=4/20
20÷5=4
4•4=16
16/20 (16/20 can reduce to 4/5 which means you did this correctly.
Now to add them keep the denominators the same and only add the numerators:
15/20 + 16/20 = 31/20
Now this as a mixed number would be 1 11/20. I hope this was helpful!
Answer:
1.) 1 1/12
2.) 1 11/20
Step-by-step explanation:
5/6+1/4
convert to common denominators
5/6 x 2/2 = 10/12
1/4 x 3/3 = 3/12
10/12+3/12=13/12
Convert to a mixed number
1 1/12
3/4+4/5
convert to common denominators
3/4 x 5/5 = 15/20
4/5 x 4/4 = 16/20
15/20+16/20=31/20
Convert to a mixed number
1 11/20
