Answer: 174
Step-by-step explanation:
Let's define the notation:
U = units digit
T = tens digit
H = hundreds digit.
Where the number is HTU.
We know that:
T = U + 3
"UTH" - "HTU" = 297.
"TU" = "HTU"/2 - 13.
First, let's wrote this correctly, and make a system of equations:
T = U + 3.
U*100 + T*10 + H - H*100 - T*10 - U = (U - H)*99 = 297.
T*10 + U = (H*100 + T*10 + U)/2 - 13 = H*50 + T*5 + U*0.5 - 13
Then we have the system of equations:
T = U + 3.
(U - H)*99 = 297
T*10 + U = H*50 + T*5 + U*0.5 - 13.
First, we can replace the first equation into the third one, so now we have only two variables.
(U - H)*99 = 297
(U +3)*10 + U = H*50 + (U + 3)*5 + U*0.5 - 13.
Now we can isolate H in the first equation and get:
(U - H) = 297/99
H = -297/99 + U.
Now we can replace it into the other equation:
(U +3)*10 + U = (-297/99 + U)*50 + (U + 3)*5 + U*0.5 - 13.
Now let's solve this for U.
U*10 + 30 + U = U*50 -150 + 5*U + 15 + U*0.5 - 13
11*U + 30 = U*(50 + 5 + 0.5) - 148
30 +148 = U*(55.5 - 11) = U*44.5
U = 178/44.5 = 4.
Then using the previous equations:
T = U + 3 = 4 + 3 = 7
H = -3 + U = -3 + 4 = 1.
Then our number is:
174.

Statins are used to keep cholesterol in check and are a top-selling drug in the U.S. The equation: S − 1.9 x = 4.9 gives the amount of sales ( S ) of statin in billions of dollars x years after 1998. According to this equation, how much will/did people in the U.S. Spend on statins in the year 2005? Answer: People in the U.S. Will spend billion dollars on statins in 2005.
Answer:
People in the U.S. Will spend 18.2 billion dollars on statins in 2005.
Step-by-step explanation:
Given:
S − 1.9x = 4.9
Where,
S = sales of statin in billions of dollars
x = years after 1998
how much will/did people in the U.S. Spend on statins in the year 2005?
2005 is a year after 1998
Number of years = 2005 - 1998
= 7
x = 7 years
S − 1.9x = 4.9
S - 1.9(7) = 4.9
S - 13.3 = 4.9
Add 13.3 to both sides
S = 4.9 + 13.3
= 18.2
People in the U.S. Will spend 18.2 billion dollars on statins in 2005.

Answer:
y=-5/3x-1
Step-by-step explanation:
Of course! Two parallel lines will have the same slope. So, we have to eliminate all equation that dont have the slope -5/3. We are left with the third option.
Answer:
[tex]y = - \frac{5}{3}x - 1 [/tex]
Step-by-step explanation:
[tex]since \: both \: lines \: have \: te \: same \: slope : \\ then \: the \: equation \: of \: a \: line : slope \: intercept \\ \: is \: given \: by : \\ y - y_{1} = m(x - x_{1}) \\ but \: the \: slope, \: m \: = - \frac{5}{3} \\ y - 4 = - \frac{5}{3}(x - ( - 3)) \\ y - 4 = - \frac{5}{3}x - 5 \\ y = - \frac{5}{3}x - 1 [/tex]
Tracy has a cell phone plan that provides 250 free minutes each month for a flat rate of $29. For any minutes over 250, Tracy is charged $0.35 per minute. Which of the following piecewise functions represents charges based on Tracy's cell phone plan?
Answer:
[tex]\frac{29,x\leq 250}{29+0.35(x-250)x\geq 250}[/tex]
Step-by-step explanation:
Let x represent the total time spent calling and f(x) represent the charges.
Since Tracy is charged $29 for 250 free minutes, hence:
For x ≤ 250, f(x) = $29
Tracy is charged an extra $0.35 per minute for calls over 250 minutes, hence:
For x ≥ 250, f(x) = 29 + 0.35(x - 250)
Therefore this can be represented by the piecewise function:
f(x)= [tex]\frac{29,x\leq 250}{29+0.35(x-250)x\geq 250}[/tex]
Mark Lomonaco And deven Hughes pushes twenty five new tables for $29.95 each. they received a 15% discount off the total gross amount of the tables because they purchased more than five tables. Sales tax in their country is 8.75 %
Answer:
4.58
Step-by-step explanation:
$29.95(15%) = 4.4925+8.75% = 4.4925+0.0875 = 4.58
Given f(x) = -2x and g(x) = 4x - 8, find h(x) = f(x) + g(x).
f(x) = -2x and g(x) = 4x - 8, find h(x) = f(x) + g(x).
Replace f(x) and g(x) with their given values:
h(x) = -2x + 4x -8
Combine like terms:
h(x) = 2x -8
Solve: x2 − x − 6 x2 = x − 6 2x 2x 12 x after multiplying each side of the equation by the lcd and simplifying, the resulting equation is .
On factorization of the equation x² − x − 6 = 0. Then the values of x are −2 and 3.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The equation is given below.
x² − x − 6 = 0
On factorization, we have
x² − 3x + 2x − 6 = 0
x(x − 3) + 2(x − 3) = 0
(x − 3)(x + 2) = 0
x = −2, 3
The values of x are −2 and 3.

x^2 -1 - 5(x-1)
Step-by-step explanation:
p(x) = x^2 - 1 and q(x) = 5(x - 1)
p(x) - q(x) = x^2 - 1 - ( 5(x-1))

What is the slope of a line that is perpendicular to the
graph of y=1/6x+8 ?
Select one:
-6
6
1/6
-1/6
Answer:
A. -6
Step-by-step explanation:
The slope of the line that is perpendicular to the graph y = ⅙x + 8, is a negative reciprocal of the slope of the graph, y = ⅙x + 8.
What this means is that, if you multiply the slope of y = ⅙x + 8, and the slope of the line perpendicular to it, you would have -1. That is [tex] m_1 * m_2 = -1 [/tex].
Where,
[tex] m_1 [/tex] = slope of y = ⅙x + 8.
[tex] m_2 [/tex] = slope of the line perdendicular to y = ⅙x + 8.
The slope of y = ⅙x + 8 is ⅙.
Substitute [tex] m_1 [/tex] = ⅙ into [tex] m_1 * m_2 = -1 [/tex], to find the slope [tex] (m_2) [/tex] of the line that is perpendicular to the graph of y = ⅙x + 8.
[tex] \frac{1}{6} * m_2 = -1 [/tex]
Multiply both sides by 6
[tex] \frac{1}{6} * m_2 * 6 = -1*6 [/tex]
[tex] 1*m_2 = -6 [/tex]
[tex] m_2 = -6 [/tex]
The slope of the line that is perpendicular to the graph of y = ⅙x + 8 is -6.
Evaluate the function rule below when x= -2

Answer:
Given function: [tex]f(x)=-x+2[/tex]
To evaluate the function when [tex]x=-2[/tex], substitute the given value for [tex]x[/tex] into the function and solve:
[tex]\implies f(-2)=-(-2)+2[/tex]
[tex]\implies f(-2)=2+2[/tex]
[tex]\implies f(-2)=4[/tex]

A rectangular table that is placed lengthwise against a wall is 8 feet long
and 4 feet wide. Balloons will be attached 8 inches apart along the three
exposed sides, with one balloon at each of the four corners. How many balloons are needed?
Considering the perimeter of the rectangular table, it is found that 36 ballons are needed.
What is the perimeter of a rectangle?The perimeter of a rectangle of length l and width w is given by:
P = 2(l + w).
In this problem, the dimensions of the table are l = 8 ft and w = 4 ft, hence the perimeter is of:
P = 2(l + w) = 2 x 12 = 24 ft.
Ballons will be attached 8 inches = 2/3 feet along the perimeter, hence the number of ballons needed is given by:
[tex]n = \frac{24}{\frac{2}{3}} = 36[/tex]

The volume of the cylinder is ?
The volume of a cylinder with the same radius and double the height is ?
Answer:
Step-by-step explanation:
The volume of the original cylinder = pi * r^2 * h
Givens
r = 6 in
h = 3 in
pi = 3.14
Solution
V = pi * r^2 * h
V = 3.14 * 6^2* 3
V = 3.14 * 36 * 3
V = 339. 12
Part 2
If you double the height, you will double the volume
V = 3.14 * 36 * 6
V = 678.24
