Answer:
In the new mixture, the percentage of water with respect to its total is 13.33%.
Step-by-step explanation:
Given that in a liter of mixture 20% of it was water and the remaining 80% was pure milk, and that half a liter of wine was added to that liter of mixture, to determine the percentage of water in the new mixture is necessary to perform the following calculation:
20 + 80 + 50 = 150
150 = 100
20 = X
((20 x 100) / 150) = X
2,000 / 150 = X
13.33 = X
Thus, in the new mixture, the percentage of water with respect to its total is 13.33%.

The product of two consecutive even integers is 8. Find the integers.
Note: each set of brackets represents one solution
Answer:
2 and 4
Step-by-step explanation:
you can just try and u'll get 2 and 4
Answer:
-4 and -2 or 2 and 4Step-by-step explanation:
Let the integers be x and x+2
Then we have:
x(x+2) = 8x^2 + 2x = 8x^2 + 2x + 1 = 9(x + 1)^2 = 3^2x + 1 = ± 3x = -1 ± 3x = -4 and x = 2The numbers are:

Answer:
xx - 5% + 5% dollars
Step-by-step explanation:
he was given a 5%coupon meaning 5% was deducted.
then a 5% sales tax was added presenting us with the expression:

explain how to determine if the two expressions are equivalent using x=6 and x=10
8x+40. 8(x+5)
Answer:
Step-by-step explanation:
if they're equivalent, when you plug in either 10 or 6 for x, they should both equal the same.
x=10, 8(10)+40=120.... 8(10+5)=120. so they equal. also test 6
8(6)+40=88. 8(6+5)=88
they are equivalent since they both equal each other, no matter what you plug in. reason being that the 8(x+5) is the factorized version of 8x+40
Answer:
By putting both values of x in the expression, it can be concluded that both expressions are equivalent.
Step-by-step explanation:
The expressions can be evaluated to be equivalent by putting the values given
The expressions are:
8x+40 and 8(x+5)
Putting x = 6 in both
[tex]8x+40\ and\ 8(x+5)\\8(6)+40\ \ ; \ 8(5+6)\\48+40\ \ \ \ ; \ \ 8(11)\\88\ \ \ \ \ \ \ \ \ \ \ ; \ \ 88[/tex]
The values of both expressions are same on x=6
Now putting x = 10
[tex]8x+40\ and\ 8(x+5)\\8(10)+40\ \ ; \ 8(10+6)\\80+40\ \ \ \ ; \ \ 8(16)\\120\ \ \ \ \ \ \ \ \ ; \ \ 120[/tex]
The values of both expressions are same on x = 10
Hence,
By putting both values of x in the expression, it can be concluded that both expressions are equivalent.

Help me with this question pleaseee
Answer:
Step-by-step explanation:
Remark
If the horizontal lines are parallel, then 2x + 20 = 3x - 10
Equation
2x + 20 = 3x - 10
Add 10 to both sides
2x + 20 + 10 = 3x
Subtract 2x from both sides
30 = x
2x + 20 = 2*30 + 20 = 80
Answer:
x = 30 and both the angles are 80°
__________________________________________________________
In the given figure,
∠(2x + 20) = ∠(3x - 10) [corresponding angles]
20 = x - 10 [subtracting 2x from both sides]
x = 30 [adding 10 on both sides]
Value of the angles:
the questions required us to find the measure of a certain ∠XAE, but since we cannot see an ∠XAE in the image provided, we will find the measure of both the angles [let ∠(2x + 20) = ∠1 and ∠(3x-10) = ∠2]
Measure of ∠1:
We are given that the magnitude of ∠1 is:
∠1 = 2x + 20
since x = 30
∠1 = 2(30) + 20 [replacing the value of x]
∠1 = 80°
Measure of ∠2:
We are given that the magnitude of ∠2 is:
∠2 = 3x - 10
since x = 30
∠2 = 3(30) - 10 [replacing the value of x]
∠2 = 80°

the cost of 12 kg sugar is $240 what will be the cost of 3 kg sugar
Question:
The cost of 12 kg sugar is $240 what will be the cost of 3 kg sugar.
Given:
Cost of 12 kg sugar = $240To find?
cost of 3 kg sugarAnswer :
To find cost of 3kg sugar first we have to find cost of 1 kg sugar.
Cost of 1 kg sugar = Cost of total no. of sugar ÷Total sugar Cost of 1 kg sugar = $240/12Cost of 1 kg sugar = $20Now Let's find cost of 3 kg sugar
Cost of 3kg sugar = total no of sugar ×Cost of 1 kg sugar
Cost of 3kg sugar = 3×$20
Cost of 3kg sugar = $60

Which inequality is true
The mean of a distribution is 276, while the median is 276. Which of these
statements is likely to be true about the distribution?
A. It is negatively skewed.
B. It is positively skewed.
C. It is not symmetric.
D. It is not skewed.
Answer:
It is not skewed.
Step-by-step explanation:
When the mean of a distribution is equal to that of its median, the distribution is not skewed.
Here, mean and median of a distribution is 276. It means, both mean and median are same. It would mean that the distribution is not skewed.
Out of the given options, the correct option is (d) "It is not skewed".
