Answer:
8 Hours
Step-by-step explanation:
First, you have to subtract the 25$ because we already know that that is a stable value (meaning it will not change)
Then, you have to divide 440 by 55 to get an answer of 8 hours for the session :D
To find total multiply 55 by number of hours (h) and then add 25:
Total = 55h + 25
Given the total solve for h:
465 = 55h + 25
Subtract 25 from both sides
440 = 55h
Divide both sides by 55
H = 440/55
H = 8
It was 8 hours
If G(x)=5x-2, find G^-1(x).
A.-5x+2
B.(x+2)/5
C.(x/5)+2
Answer:
C.
Step-by-step explanation:
G(x) = 5x - 2
G^-1 = everything will become a fraction with one as the numerator and all negatives on the bottom become a positive constant.
G^-1(x) = (x/5) + 2
Mr. Burnett, the school librarian, is ordering new keyboards and mice for all of the school's
computer labs. Each keyboard costs $13.50, and each mouse costs $6.50. There are 3
computer labs in the school, and each computer lab has s computer stations.
Pick all the expressions that represent how much Mr. Burnett will spend on new keyboards
and mice.
3(13.50s + 6.50s)
20.00s + 3
(13.50s + 3) + (6.50s + 3)
3(20.00)
Answer:
so 3 X 13.50 + 6.50) so add first because of this order of operations (pemdas), parenthesis, exponent, multiply, divide, add, subtract

5. The first time that Jordan ran for class president, he recelved 10% of the votes. This year, when
he ran again, he received 6 times as many votes as he did when he ran the first time. There
were a total of 180 votes in each election. How many votes did Jordan receive this year
HURRY PLEASE
Answer:
108 votes
Step-by-step explanation:
There were 180 votes in the election and Jordan received 10% of them.
180 × 0.10 = 18
Jordan received 18 votes the first time. This year, he received 6 times as many votes.
18 × 6 = 108
Jordan received 108 votes this year.
Hope that helps.

Answer:
y = -2x + 5
Step-by-step explanation:
To find the slope, you need to pick two points and put into the slope formula. It doesn't matter which ones, you will get the right answer regardless. I used (-3, 11) and (2, 1).
[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} } \\m=\frac{11 -1 }{-3 -2 } \\m=\frac{10 }{-5 } \\m=-2[/tex]
Now that you have the slope, you can plug it into point-slope form to find the equation in slope-intercept form. You will also need to plug one of the given points. Again, it doesn't matter which one.
[tex]y-y_{1}=m(x-x_{1} )\\y-1=-2(x-2)\\y-1=-2x+4\\y=-2x+5[/tex]
List the subsets of the set { dog,cat,rabbit}
Answer: so dog goes to cat, dog goes to rabbit and cat goes to rabbit I think
Step-by-step explanation:
The possible Subset is
Sub sets : {dog}, {cat}, {fish}, {dog, cat}, {dog, fish}, {cat, fish}, {dog, cat, fish}.
What is a subset ?If each constituent of a set A is a member of a different set B, then the sets A and B are subsets of one another.
To put it another way, A⊂B A and B stand for the subset connection.
Set A is referred to as a subset of Set B if all of the elements in Set A are also found in Set B. In other words, Set A is a part of Set B. A is the subset of B, for instance, if set A contains the elements X, Y, and set B contains the elements X, Y, and Z.
We have set,
Set : {dog, cat, fish}
Then, the subset contain the elements of set A as
Sub sets : {dog}, {cat}, {fish}, {dog, cat}, {dog, fish}, {cat, fish}, {dog, cat, fish}.

5.401 \times 10^{-1} = {?}5.401×10 −1 =?
Answer:
2.005 x 10^2
Step-by-step explanation:
Consider the following statements:
I. As far as the significance level is concerned, a two-tailed hypothesis test is more accurate than a one-tailed hypothesis test.
II. A point estimation procedure utilizes information in a sample to arrive at two points, one positive and one negative in order to estimate the population parameter of interest.
a. I and II are both true.
b. I and II are both false.
c. I is true and II is false.
d. I is false and II is true.
e. I is false and II is sometimes true.
Answer:
b. I and II are both false.
Step-by-step explanation:
I. For a significance level, the two tailed hypothesis is not always accurate than the one tailed hypothesis test. The hypothesis testing is carried to find out the correctness of a claim of a population parameter. The two tail hypothesis test which used both positive and negative tails of the distribution is not always more accurate than one tailed test.
II. The process of the point estimation involves the utilization of the values of a statistic which is obtained from the sample data to obtain the best estimate of a corresponding unknown parameter in the given population.
Hence, both the statements are false.

Step-by-step explanation:
Peggy and her mom have been living alone in an island ever since Peggy was born. To keep track of how old her daughter is, every day after Peggy was born, her mom carves a tick mark into a tree.
One day, Peggy's mom counted 2000 tick marks on the tree. How many years old is Peggy, rounded off to the nearest year? Remember that a year has 365 days.
Answer:
5 years
Step-by-step explanation:
Divide 365 by 2000. The answer is 5.4794. Rounded to the nearest whole it is 5.
Answer:
5 years
Step-by-step explanation:
What we know:
- 2000 days passed (since each tick mark represents a day)
- One year has 365 days
Let [tex]x[/tex] represent the number of years that passed.
If each year has 365 days, 365 multiplied by the number of years that passed should equal 2000.
[tex]365x=2000[/tex]
Divide both sides by 365 to isolate x
[tex]\frac{365x}{365} =\frac{2000}{365}[/tex]
[tex]x[/tex] ≈ [tex]5[/tex]
Therefore, Peggy is 5 years old.
I hope this helps!

Solve each system using substitution.
1. 4x= 3y-2 ; 18= 3x+y
Answer:
y = 6
Step-by-step explanation:
so since you have 2 variables, you need to find a substitution for one of them.
let's do that for y
let y = something in the second equation.
y = 18 - 3x
then plug this into the first equation
4x = 3(18 - 3x) - 2
4x = 54 - 9x -2
4x = 52 - 9x
13x = 52
x = 4
now you have x, plug it into any of the equations to find y.
4(4) = 3y - 2
16 = 3y - 2
18 = 3y
y = 6
Answer:
x = 4, y = 6
Step-by-step explanation:
Substituting y into 1:
4x= 3y-2 -----1
18= 3x+y -----2
Isolate the y in 2.
y = 18-3x -----3
Substitute 3 into 1.
4x= 3(18-3x)-2
Evaluate.
4x = 54-9x-2
Keep like terms together.
4x+9x = 54-2
Simplify.
13x = 52
Find x.
x = 52 ÷ 13
= 4
Substitute x into 3.
y = 18-3(4)
Evaluate.
y = 18-12
Find y.
y = 6

Kevin and his children went into a restaurant and he bought $31.50 worth of hotdogs and drinks. Each hotdog costs $4.50 and each drink costs $2.25. He bought 3 times as many hotdogs as drinks. Graphically solve a system of equations in order to determine the number of hotdogs, x,x, and the number of drinks, y,y, that Kevin bought.
Answer:
6 hot dogs, 2 drinks
Step-by-step explanation:
let y = number of hot dogs
let x = number of drinks
system:
y = 3x
4.5y + 2.25x = 31.50 (standard form: y = -1/2x + 7)
if you graph the system, lines intersect at (2, 6)
Answer:
y=1/3 x
y=-2x+14

Shelby loves to knit scarves. Normally, it takes her 15 minutes to knit 5 inches of a scarf. She plans to make a scarf that is 30 inches long.
If she knits at the same rate, how many minutes will it take Shelby to knit the scarf?
Answer:
90 minutes
Step-by-step explanation:
let x=amount of time it would take for Shelby to knit the scarf
[tex]\frac{15}{5} =\frac{x}{30}[/tex]
cross multiply
15*30=5x
450=5x
450/5=x
x=90
It would take Shelby 90 minutes to knit a scarf that is 30 inches long.

The value of y in the system of equations is:
y = -1.
y = -3.
y = 1.
y = 3
Answer:
y = 3
Step-by-step explanation:
2x-3y = -5 --------- (1)
y = 2+x ------- (2)
substitute (2) into (1)
2x-3y = -5
2x-3( 2+x ) = -5
2x-6-x = -5
2x-x = -5+6
x = 1
substitute x = 1 into (2)
y = 2+x
y = 2+1
y = 3
