Which inequality below represents the greatest number of hours the mechanic can work without exceeding Ms. Salgado's budget?
Answer:
The mechanic will need to finish in 4 hours.
Step-by-step explanation:
100+40=140
40+40=80

How to calculate how much average household paid per year in federal gasoline taxes?To calculate how much the average household paid per year in federal gasoline taxes, we can use the following steps:
Determine the total number of gallons of gasoline consumed by the average household per year:
Total gallons = (Total miles driven) / (Miles per gallon)Total gallons = 11,340 miles / 21.4 miles per gallonTotal gallons = 530 gallons (rounded to the nearest gallon)Calculate the total amount paid in federal gasoline taxes per year:
Total taxes = (Total gallons) * (Tax rate per gallon)Total taxes = 530 gallons * $0.184 per gallonTotal taxes = $97.52According to the above we can establish that based on the given statistics, the average household paid approximately $97.52 per year in federal gasoline taxes.

There are seven quarters in the bottom of a tote bag. Three of those quarters were minted in 2019, two were minted in 2001, and two were minted in 2008. What is the probability of selecting two quarters that were both minted in years other than 2019 if the first was not replaced before the second was selected?
Answer:
[tex]P(Not\ 2019) = \frac{2}{7}[/tex]
Step-by-step explanation:
Given
[tex]n(2019)= 3[/tex]
[tex]n(2001)= 2\\[/tex]
[tex]n(2008)= 2[/tex]
[tex]n = 7[/tex] --- total
Required
[tex]P(Not\ 2019)[/tex]
When two quarters not minted in 2019 are selected, the sample space is:
[tex]S = \{(2001,2001),(2001,2008),(2008,2001),(2008,2008)\}[/tex]
So, the probability is:
[tex]P(Not\ 2019) = P(2001,2001)\ or\ P(2001,2008)\ or\ P(2008,2001)\ or\ P(2008,2008)[/tex]
[tex]P(Not\ 2019) = P(2001,2001) + P(2001,2008) + P(2008,2001) + P(2008,2008)[/tex]
[tex]P(2001,2001) = P(2001) * P(2001)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2001,2001) = \frac{n(2001)}{n} * \frac{n(2001)-1}{n - 1}[/tex]
[tex]P(2001,2001) = \frac{2}{7} * \frac{2-1}{7 - 1}[/tex]
[tex]P(2001,2001) = \frac{2}{7} * \frac{1}{6}[/tex]
[tex]P(2001,2001) = \frac{1}{7} * \frac{1}{3}[/tex]
[tex]P(2001,2001) = \frac{1}{21}[/tex]
[tex]P(2001,2008) = P(2001) * P(2008)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2001,2008) = \frac{n(2001)}{n} * \frac{n(2008)}{n - 1}[/tex]
[tex]P(2001,2008) = \frac{2}{7} * \frac{2}{7 - 1}[/tex]
[tex]P(2001,2008) = \frac{2}{7} * \frac{2}{6}[/tex]
[tex]P(2001,2008) = \frac{2}{7} * \frac{1}{3}[/tex]
[tex]P(2001,2008) = \frac{2}{21}[/tex]
[tex]P(2008,2001) = P(2008) * P(2001)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2008,2001) = \frac{n(2008)}{n} * \frac{n(2001)}{n - 1}[/tex]
[tex]P(2008,2001) = \frac{2}{7} * \frac{2}{7 - 1}[/tex]
[tex]P(2008,2001) = \frac{2}{7} * \frac{2}{6}[/tex]
[tex]P(2008,2001) = \frac{2}{7} * \frac{1}{3}[/tex]
[tex]P(2008,2001) = \frac{2}{21}[/tex]
[tex]P(2008,2008) = P(2008) * P(2008)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2008,2008) = \frac{n(2008)}{n} * \frac{n(2008)-1}{n - 1}[/tex]
[tex]P(2008,2008) = \frac{2}{7} * \frac{2-1}{7 - 1}[/tex]
[tex]P(2008,2008) = \frac{2}{7} * \frac{1}{6}[/tex]
[tex]P(2008,2008) = \frac{1}{7} * \frac{1}{3}[/tex]
[tex]P(2008,2008) = \frac{1}{21}[/tex]
So:
[tex]P(Not\ 2019) = P(2001,2001) + P(2001,2008) + P(2008,2001) + P(2008,2008)[/tex]
[tex]P(Not\ 2019) = \frac{1}{21} + \frac{2}{21} +\frac{2}{21} +\frac{1}{21}[/tex]
Take LCM
[tex]P(Not\ 2019) = \frac{1+2+2+1}{21}[/tex]
[tex]P(Not\ 2019) = \frac{6}{21}[/tex]
Simplify
[tex]P(Not\ 2019) = \frac{2}{7}[/tex]

what are the outliers for 0,5,6,7,8,13
Given:
The date set is:
0,5,6,7,8,13
To find:
The outliers for the given data set.
Solution:
We have,
0,5,6,7,8,13
Divide the data in two equal parts.
(0,5,6),(7,8,13)
Divide each parenthesis in two equal parts.
(0),5,(6),(7),8,(13)
Here, first quartile is [tex]Q_1=5[/tex] and the third quartile is [tex]Q_3=8[/tex].
The interquartile range (IQR) is:
[tex]IQR=Q_3-Q_1[/tex]
[tex]IQR=8-5[/tex]
[tex]IQR=3[/tex]
The data lie outside the range [tex][Q_1-1.5IQR,Q_3+1.5IQR][/tex] is called outliers.
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[5-1.5(3),8+1.5(3)][/tex]
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[5-4.5,8+4.5][/tex]
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[0.5,12.5][/tex]
The data values 0 and 13 lie outside the range [0.5,12.5].
Therefore, 0 and 13 are outliers of the given data set.

The area of a triangle is 55x^3+15x^2-25. The length of the triangle is 5x. What is the width?
Answer:
The area of a triangle =55x^3+15x^2-25
1/2×length×width=55x^3+15x^2-25
5x/2×width=55x^3+15x^2-25
width=[55x^3+15x^2-25]×2/5x
width=22x²+6x-10/x is your answer
Tenzing sold two watches at rs1200 andrs1350 respectively if he gained 20 percent on the first and 2percent on the whole what percent did he loss in second watch
9514 1404 393
Answer:
10% loss
Step-by-step explanation:
If Tenzing sold the first watch at 20% profit, his cost c can be found from ...
1200 = 1.20c
1000 = c
If Tenzing sold both watches together for 1200 +1350 = 2550, then his total cost can be found from ...
2550 = 1.02t
t = 2550/1.02 = 2500
Then his cost for the second watch was ...
2500 -1000 = 1500
The sale price of 1350 for that watch represents a multiplier m on the watch cost of ...
1500m = 1350
m = 1350/1500 = 0.90 = 1 - 0.10
Tenzing lost 10% of its cost on the second watch.

Based on a $400 loan amount, rank the following companies from the lowest to highest annual percentage rate (APR)
Answer:
Step-by-step explanation:
A = 40* (365/5)= 29.2%
B = 50*(365/12) = 15.2%
C= 80*(365/15)=19.46%
D = 100*(365/20)=18.25%
so best is B, then D , then C then A .
B,D,C,A in lowest to highest APR
As per the given data, with a base of $400 for loan amount, the ranking of all the given companies from the lowest to highest annual percentage rate is B,D,C, and A.
What is the annual percentage rate?Annual borrowing costs, including fees, are stated as a percentage and are known as the annual percentage rate, or APR. The APR is a more comprehensive indicator of how much borrowing money will cost because it includes both interest rates and application fees.
Instead of just a monthly fee or rate, the term annual percentage rate of charge refers to the interest rate for the entire year as applied to a loan, home loan, credit card, and many more. It can also be referred to as a nominal APR or an effective APR. It is a financial fee that is calculated at an annual rate.
Required calculations are as follow:
A = 40 × (365/5)= 29.2%
B = 50 × (365/12) = 15.2%
C= 80 × (365/15)=19.46%
D = 100 × (365/20)=18.25%
Therefore, the ranking of all the companies with the lowest to highest annual percentage rate are B,D,C, and A.

2. Desarrolla el cuadrado de los siguientes binomios. a) (2 + 5√) 2 = b) (√3 − √5) 2 = c) (√ + 3 − √ − 3) 2 =
Answer:
Cuando tenemos un binomio como:
(a + b)^2
El desarrollo es:
a^2 + 2*a*b + b^2
Si en cambio, el binomio es de la forma:
(a - b)^2
El desarrollo es:
a^2 - 2*a*b + b^2
Ahora simplemente usemos esas formulas en cada caso:
a) (2 + 5√)^2
(hay una raiz cuadrada ahi que no aplica a nada, asi que supongo que es un error de tipeo)
entonces tenemos que expandir:
(2 + 5)^2 = 2^2 + 2*(2)*(5) + 5^2 = 4 + 20 + 25 = 49
b) (√3 − √5)^2
= (√3)^2 - 2*(√3)*(√5) + (√5)^2
= 3 - 2*√(3*5) + 5
= 3 - 2*√15 + 5
= 8 - 2*√15
c) (√( + 3) − √( − 3))^2
Acá hago el reemplazo:
√(-3) = i*√3
Recordar que i^2 = -1
Entonces tendremos:
(√( + 3) − √( − 3))^2 = (√( 3) − i√( 3))^2
= (√3)^2 - 2*i* (√3)(√3) + (i* (√3))^2
= 3 - 2*3*i + (i^2*3)
= 3 - 6*i - 3
= - 6i

Dan invests £1500 into his bank account.
He receives 3% per year simple interest.
How much will Dan have after 2 years?
Give your answer to the nearest penny where appropriate.
Answer:
£1,725.00
Step-by-step explanation:
To calculate simple interest, we use the formula:
a = p(1 + rt)
a is the answer
p is the principle, or the starting amount of money
r is the rate, or the rate of interest (the percent)
and t is the time, or years.
First, 3% as a decimal is 0.03
So we can plug that in as r.
Then just plug the rest of the numbers in.
a = 1500(1 + 0.03 x 2)
Then just solve the equation to get 1,725.00.
Hope this helps!
