50 students were asked what they did last night. 16 said they read a book, 41 said they watched TV, 7 said they did neither, how many students did both
Answers
Answer:
14 students
Step-by-step explanation:
Given
Let:
\(b \to\) read a book
\(t \to\) watched TV
So, we have:
\(n = 50\) -- total
\(b = 16\)
\(t = 41\)
\(none = 7\)
Required
Students that did both (x)
This is calculated using:
\(Total = Books\ only + TV\ only + Both + None\)
So, we have:
\(n = (b - x) + (t - x) + x + none\)
This gives:
\(50 = (16 - x) + (41 - x) + x + 7\)
Open brackets
\(50 = 16 - x + 41 - x + x + 7\)
\(50 = 16 - x + 41 +7\)
Collect like terms
\(x = 16 - 50 + 41 +7\)
\(x = 14\)

Answers
The image of the resulting figure (quadrilateral A'B'C'D') is presented below as attachment.
How to graph a dilated quadrilateral
According to geometry and linear algebra, a dilation of a point \(P(x,y)\) with respect to another point \(G(x,y)\) is determined by the following expression:
\(P'(x,y) = P(x,y) +k\cdot [P(x,y) - G(x,y)]\) (1)
Where:
\(P'(x,y)\) - Resulting point\(k\) - Dilation factorNow we proceed to make the corresponding operations (\(A(x,y) = (-1, 3)\), \(B(x,y) = (2,0)\), \(C(x,y) = (2, -1)\), \(D(x,y) = (-3, -1)\)):
Point A'\(A'(x,y) = (-1,3)+(-0.5)\cdot [(-1,3)-(2,1)]\)
\(A'(x,y) = (-1, 3) + (-0.5)\cdot (-3, 2)\)
\(A'(x,y) = (-1, 3) + (1.5, -1)\)
\(A'(x,y) = (0.5, 2)\)
Point B'\(B'(x,y) = (2,0) + (-0.5)\cdot [(2,0)-(2,1)]\)
\(B'(x,y) = (2,0) + (-0.5)\cdot (0, -1)\)
\(B'(x,y) = (2,0) + (0, 0.5)\)
\(B'(x,y) = (2, 0.5)\)
Point C'\(C'(x,y) = (2, -1) + (-0.5)\cdot [(2,-1)-(2,1)]\)
\(C'(x,y) = (2, -1) + (-0.5)\cdot (0,-2)\)
\(C'(x,y) = (2,-1) + (0, 1)\)
\(C'(x,y) = (2, 0)\)
Point D'\(D'(x,y) = (-3,-1) + (-0.5)\cdot [(-3, -1)-(2,1)]\)
\(D'(x,y) = (-3,-1) + (-0.5)\cdot (-5, -2)\)
\(D'(x,y) = (-3, -1) + (2.5, 1)\)
\(D'(x,y) = (-0.5, 0)\)
Lastly, we proceed to graph both the original and resulting figure. \(\blacksquare\)

Factor the numerator and denominator:
\(f(x)=\frac{(x-2)(x+2)}{(x-2)(x-10)}\)

Answers
In a linear model:
\(f(x)=mx+b\)The coefficient of x, which is m, is the rate of change of the function f with respect to changes in the value of x. In the context of the problem, the coefficient of x tells us the amount of money that Jim earns per hour.
The constant term b is the initial value of the function f when x=0.
Since the given linear model has no constant term, it means that the initial value is 0. In other words, Jim will earn $0 if he works 0 hours.
Therefore, the correct choice is Option A) There is no initial amount of money he gets paid prior to starting.

Ana works 25 hours a week at the library. If she is paid $10 an hour, and her net salary each week is $212.50, what percent of her salary is withheld for taxes?
Answers
Approximately 17.65% of Ana's salary is withheld for taxes.
To calculate the percentage of Ana's salary that is withheld for taxes, we need to determine the amount of tax withheld and then express it as a percentage of her net salary.
Number of hours worked per week (H) = 25 hours
Hourly wage (W) = $10
Net salary (S) = $212.50
Calculate the total earnings before taxes:
Total earnings = Hours worked * Hourly wage
Total earnings = 25 hours * $10/hour
Total earnings = $250
Determine the amount of tax withheld:
Tax withheld = Total earnings - Net salary
Tax withheld = $250 - $212.50
Tax withheld = $37.50
Calculate the percentage of salary withheld for taxes:
Percentage withheld = (Tax withheld / Net salary) * 100
Percentage withheld = ($37.50 / $212.50) * 100
Percentage withheld ≈ 17.65%
Therefore, approximately 17.65% of Ana's salary is withheld for taxes.

-4<3(2)-6
-4<6-6
-4<0
Now let’s substitute (1,0) into the inequality:
y<3x-6
0<3(1)-6
0<3-6
0<-3
This is false as 0 is greater than -3, not less than. Hope this helps :)

For the following amount at the given interest rate compounded continuously, find (a) the future value after 9 years, (b) the effective rate, and (c) the time to reach $10 comma 000.
$5200 at 3.7%
Answers
(a) the future value after 9 years is $7254.76 .
(b) the effective rate of interest is 3.769% .
(c) the time required to reach $10000 is 1.77 years .
The Continuous Compounding formula for the principal P , rate of interest r , and time t is
A = P×\(e^{rt}\)
In the question ,
it is given that
Part(a)
the amount deposited (P) = $5200
rate percent (r) = 3.7% = 3.7/100 = 0.037
time = 9 years
Amount = 5200×\(e^{0.037\times9}\)
= 7254.76
the future value after 9 years is $7254.76 .
Part(b)
the effective rate is calculated using the formula
effective rate = \(e^{r}\) - 1
effective rate = \(e^{0.037}\) - 1
= 1.03769 - 1
= 0.03769
= 3.769%
Part(c)
the time to reach $10000 is calculated using the formula
10000 = 5200\(e^{0.037\times t}\)
\(e^{0.037\times t}\) = 10000/5200
\(e^{0.037\times t}\) = 100/52
taking ㏑both the sides , we get
0.037×t×㏑(e) = ㏑(100/52)
0.037t = 0.65392
t = 0.65392/0.037
t = 1.76735
t ≈ 1.77 years
Therefore , (a) the future value after 9 years is $7254.76 .
(b) the effective rate of interest is 3.769% .
(c) the time required to reach $10000 is 1.77 years .

we can then represent the digit as '1'.
The value of number's hundreds place can be represented as 100
we can as well represent the number's hundredths place as 0.01
the number of times the value of the hundreds place digit exceeds the value of the hundredths place digit can be expressed as 100/0.01 =(100*100)/1 = 10, 000

The water usage at a car wash is modeled by the equation W(x) = 5x3 + 9x2 − 14x + 9, where W is the amount of water in cubic feet and x is the number of hours the car wash is open. The owners of the car wash want to cut back their water usage during a drought and decide to close the car wash early two days a week. The amount of decrease in water used is modeled by D(x) = x3 + 2x2 + 15, where D is the amount of water in cubic feet and x is time in hours. Write a function, C(x), to model the water used by the car wash on a shorter day. C(x) = 5x3 + 7x2 − 14x − 6 C(x) = 4x3 + 7x2 − 14x + 6 C(x) = 4x3 + 7x2 − 14x − 6 C(x) = 5x3 + 7x2 − 14x + 6
Answers
W(x) - C(x) = 2(W(x) - C(x))
Solving this equation for C(x), we get:
C(x) = (W(x) - 2W(x))
= W(x)(1 - 2)
= (5x3 + 9x2 - 14x + 9)(1 - 2)
= (5x3 + 7x2 - 14x + 6)
Therefore, the function C(x) to model the water used by the car wash on a shorter day is:
C(x) = (5x3 + 7x2 - 14x + 6)
