What is the N in 0.5w + 15 =20
Answer: 10
Step-by-step explanation:
I’m not sure where the N fits into the equation, but if you are finding the amount that w holds, 10 is correct.
Reverse the equation: 20=15+.5w
Now move .5 over and do 20-15 which equals 5.
.5w=5
5 divided by .5 gives you the answer of 10. 10•.5=5 which means 10 is your answer!
Answer:
w = 10
Step-by-step explanation:
Rectifying mistake in question,
→ Value of w in 0.5w + 15 = 20.
Given equation,
→ 0.5w + 15 = 20
Now the value of w will be,
→ 0.5w + 15 = 20
→ 0.5w = 20 - 15
→ 0.5w = 5
→ w = 5/0.5
→ [ w = 10 ]
Hence, the value of w is 10.

Answer:
\(f^{-1}\left(f(576)\right)=\boxed{576}\)
\(f^{-1}(-7)+f(-7)=\boxed{13}\)
Step-by-step explanation:
The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).
Given table:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)
Inverse function:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)
If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).
Therefore:
\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)
The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.
The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.
Therefore:
\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)
Manuel deposited $15,000 in an account that earns 4.25% simple interest.
- He did not make additional deposits; he did not make withdrawals.
-How much interest will Manuel have earned on his investment at the end of 3 years.
Answer:
$1912.50
Step-by-step explanation:

I have no idea about number 2 though sorry
Answer:
23 --> 27
36 --> one solution; infinitely many solution; no solutions
Step-by-step explanation:
23: We know that the three angles add up to 180 in a triangle. In this case, 180 = (3x - 9) + (6x) + (45 - x)
180 = 3x + 6z - x - 9 + 45
180 = 8x + 36
144 = 8x
x = 18
m∠C = 45 - x
m∠C = 45 - (18)
m∠C = 27
36: It's just requires some simplifying.
(2x - 3)/3 = -2x/3 - 1/9
3(2x - 3) = -6x - 1 <-- multiplied both sides by 9 to get rid of fractions
6x - 9 = -6x - 1
12x - 9 = -1
12x = 8
x = 2/3 <-- There is only one solution to this equation.
(2x - 3)/3 = 2x/3 - 1
(2x - 3)/3 = 2x/3 - 3/3
(2x - 3)/3 = (2x - 3)/3 <-- Same equation means that the line will overlap each other infinitely, so there are infinitely many solutions. If you simplify it further you will just get 0=0.
(2x - 3)/3 = 2x/3 - 1/9
(2x - 3)/3 = 6x/9 - 1/9
(2x - 3)/3 = (6x - 1)/9
9(2x - 3) = 3(6x - 1) <-- cross multiplication method
18x - 27 = 18x - 3 <-- Same slope but never touching.
-27 = -3 <-- false, so there are no solutions.

Georgia Connections Academy is selling tickets to its Spring Fling. Adult tickets cost $4 and student tickets cost $2.50. The school makes $2,820. Write an equation that represents this situation to find the cost of all adult and student tickets sold. Use the variable s for student tickets and a for adult tickets sold.
Answer:
Step-by-step explanation:
We use a for Adult and s for Student.
Assuming this, you have to start by writing two equations from the information provided:
900 total tickets were sold
a+s=900 ------(i)
they made $2,820 and adult tickets cost $4 and kids tickets cost $2.50
2820=4a+2.5s ------(ii)
lets solve for a in the first equation:
a=900-s
we can plug this into the second equation and solve for s
2820=4(900-s)+2.5s
2820=3600-4s+2.5s
2820=3600-1.5s
-780=-1.5s
s=520
we can plug this into the first equation and solve for a:
a+520=900
a=380
Total adult ticket sold : 380
Total student ticket sold = 520
Cost of adult tickets = 380 * 4 = $1520
Cost of student tickets = 520 * 2.5 = $1300

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

2+(5+y) I need help pls! If you know the answer to this problem, please explain, THANK YOU!!!
Answer:
y= -7
Step-by-step explanation:
I'm not sure if this is what you are looking for but here you go!
If the equation is set equal to zero.
2+(5+y)=0 This is the original expression, we need to find the value for y.
5+y= -2 We move the two to the right to remove it from the left side of
the equation.
y= -7 We repeat the same thing as we did in the last step, except
with the value 5. This then gives us our y-value, which is -7.
I hope this helps!
Answer:
y+7
Step-by-step explanation:
Take them out of the parenthesis and it is 2+5+y and then do 2+5 which is 7 so y+7 is the answer.

Answer:
Step-by-step explanation: Each cube has a total of 6 sides. In the model, the top cube has 1 "hidden" side/1 side that is not exposed to the paint, the bottom middle has 1 "hidden" side, the right bottom cube has 1 "hidden" side, and so does the left. Adding up all the sides that are not exposed to the paint, there is a total of 4 white sides.
Rasheem runs 1/5 miles in 2 minutes.
What is Rasheem’s speed in miles per minute?
Explain if you can. :)
Answer:
10 minutes per mile
Step-by-step explanation:
Rasheem runs 1/5 miles in 2 minutes. What you need to do is find how many minutes it takes for 1 whole mile. To do this, you have to first see what you multiply to 1/5 to get to 1. As you know, you do 1/5 x 5/1 (or 5) to get to one. Since you did that 1/5, you also need to multiply 2 x 5, which is 10. This gives you the answer that Rasheem was running 10 minutes per mile.
Hope it helped! :)
