Answer:
5 hr
Step-by-step explanation:
tony worked for 6 hr on sunday so he got $30 and he will only need 5hr bc 5hr x $5 = 25 so in total 55
The number of hours on Saturday in which Tony did babysit will be given as 5 hours.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Tony gets paid $5 per hour to babysit his cousin.
This weekend, he babysat on both Saturday and Sunday.
He made a total of $55.
Tony babysat for 6 hours on Sunday.
Let the number of hours be x on Saturday.
Then we have the equation that will be
x × 5 + 6 × 5 = 55
5x + 30 = 55
5x = 25
x = 5

Name the constant of variation for y equals 1/4x then find the slope of the (0,0) and (4,1)... please
Answer:
Constant of variation: 1/4
Slope of the line: 1/4
Step-by-step explanation:
The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.
The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

Given the triangle below with centroid G, determine the following values.
If EG=3.5, then GB= and BE= If AD=15, then AG= and DG= If CG=6x, then FG- and CF=
Answer:
GB = 7
BE = 10.5
AG = 10
DG = 5
FG = 3·x
CF = 9·x
Step-by-step explanation:
The given parameters are;
The centroid of the ΔABC = G
Segments CF, BE, and AD are median lines
EG = 3.5 Given
∴ EG = 1/3 × BE by definition of the properties of median line
∴ BE = 3 × EG = 3 × 3.5 = 10.5
BE = 10.5
GB = 2/3 × BE = 2/3 × 10.5 = 7 by definition of the properties of median line BE
GB = 7
Similarly;
Given that AD = 15, AG = 2/3 × AD = 2/3 × 15 = 10 by definition of the properties of median line AD
AD = 10
DG = 1/3 × AD = 1/3 × 15 = 5 by definition of the properties of median line AD
DG = 5
Similarly;
Given CG = 6·x
FG = 1/3 × CF
CF = 3 × FG
CG = 2/3 × CF = 2/3 × 3 × FG
∴ CG = 2 × FG
FG = CG/2 = 6·x/
2 = 3·x
FG = 3·x
CF = 3 × FG = CF = 3 × 3 × x = 9·x
CF = 9·x

A pet shop sells goldfish for $ 9 per dozen. How much would 6 goldfish cost? How many goldfish could you buy with $50?
Answer:
6 goldfish = $4.50. You can buy 66 goldfish with $50
Step-by-step explanation:
We know that dozen is 12, so 12 goldfish would be $9. To find how much one goldfish costs we would divide 9 and 12. 9÷12 is 0.75. So one goldfish is $0.75.
To find 6 goldfish just multiply 0.75 to 6. 6 goldfish would be $4.50.
We know that 0.75 times 100 would be 75 so you can only buy less than 100 goldfishes. You can buy 66 goldfishes with $50.
If this helped, I would appreciate it if you marked me brainliest. Have a nice day!

Step-by-step explanation:
plug in 6 for x and 20 for y in both equations and solve.
Line c: 20 = 6 + 14
20 = 20
Line d: 20 = 3(6) + 2

Answer:
x = 19
Step-by-step explanation:
l, m and n are the parallel lines.
Two transversal lines are intersecting these parallel lines.
By Intercept theorem,
Lengths of intercepts between the parallel lines are proportional.
[tex]\frac{38}{8}=\frac{x}{4}[/tex]
x = [tex]\frac{4\times 38}{8}[/tex]
x = 19
Therefore, x = 19 will be the answer.

What is the total cost for x months?c.Graph the cost of the cell phone plan over a period of two years using month as the units of time be sure to label your axes and scale them by labeling each grid line with a number.d.Is there a portions relationship between time and the cost of the cell phone plan.e. Draw a line a parallel to the line you graphed that goes through the point(0,350) suppose that this line represents the pricing plan for another company.What is the startup fee and monthly cost for this plan?
Answer:
a. $250
b. The total cost for x month is $200 + $50 × x
c. Please see the attached graph
d. Yes, there is a proportional relationship between time and the cost of the cell phone plan
e. $350
Step-by-step explanation:
The given parameters are;
The costs to start on the cell phone cell = $200
The charge each month = $50
a. The total cost to use the cell phone plan for 1 month = Start up fee + Monthly charge = $200 + $50 = $250
b. The total cost for x month, c = $200 + $50 × x
c. Please see the attached graph
d. Yes, there is a proportional relationship between time and the cost of the cell phone plan
e. The line parallel to the line graphed that goes to the point (0, 350), is given as follows;
y = m·x + c
Where;
m = 50
y - 350 = 50 × (x - 0)
y = 50·x + 350
The startup fee is given by the total cost at x = 0, when the monthly fee is excluded, which gives;
c = 50 × 0 + 350 = 350
The startup fee for the pricing plan = $350.
The startup fee and monthly cost for this plan according to the question is :
Part a:
The total cost to use the cell phone plan for 1 month = Start up fee + Monthly charge
Total Cost = $200 + $50 Total Cost = $250 The total cost to use the cell phone plan for 1 month is $250.Part b:
The total cost for x month, c = $200 + $50 × x The total cost for x month is $200 + $50 × x c.Please see the attached graph
Part c:
Yes, there is a proportional relationship between time and the cost of the cell phone plan .
Part e:
The line parallel to the line graphed that goes to the point (0, 350), is given as follows;
y = m·x + c
Where;
m = 50 y - 350 = 50 × (x - 0) y = 50·x + 350
The startup fee is given by the total cost at x = 0, when the monthly fee is excluded, which gives;
c = 50 × 0 + 350 = 350
Yes, there is a proportional relationship between time and the cost of the cell phone plan e. $350
The given parameters are; The costs to start on the cell phone cell = $200 The charge each month = $50
The startup fee for the pricing plan = $350.

Graph this system of equations.
1.15x + 0.65y = 8.90
x − 3y = -15
Answer:
We have the equations:
1.15x + 0.65y = 8.90
and
x − 3y = -15
First, let's write them in the slope-intercept form:
The first one will be:
y = -(1.15/0.65)*x + 8.90/0.65
The second:
y = (1/3)*x + 15/3 = (1/3)*x + 5.
then our system is:
y = -(1.15/0.65)*x + 8.90/0.65
y = (1/3)*x + 5.
To graph each line, you can just evaluate the line in two points (for x = 0 and x = 1, for example) and then locate those points in the coordinate axis, and then draw a line that connects them.
For example with the second line:
y(0) = (1/3)*0 + 5 = 5
then we have the point (0,5)
and
y(3) = (1/3)*3 + 5 = 8
Then we have the point (3,8)
With the first equation may be a little harder, as the coefficients are not whole numbers, we can rewrite it as:
y = (1.15/0.65)*x + 8.90/0.65 = (115/65)*x + (890/65)
Where i multiplied and divided by 100 the numerators and denominators in the right side, so now is easier to work with it.
The points you can use are:
y(0) = (115/65)*0 + (890/65) = 13.7
the point is (0, 13.7)
and:
y(1) = (115/65)*1 + (890/65) = 15.5
The point is (1, 15.5)
Below you can see the graphs of both functions:
blue: y = -(1.15/0.65)*x + 8.90/0.65
red: y = (1/3)*x + 5
The answer is in the picture below!
how would I solve the system x + 2y = 13, -x + y = 5 when using elimination
Answer:
x + 2y = 13}(add the both eqns)
-x + y = 5}
x +(-x) = 0
2y + y = 3y
13 + 5 = 18
then,
3y = 18
y = 6
from
x + 2y = 13
x = 13 - 2(6)
x = 1

A bag containing food has mass 3.813 kg. When the bag is empty its mass is 257 g. Find in kilograms the mass of the fruit
Answer:
I think it is 0.257 kg
Step-by-step explanation:
To change units from the gram to kilogram, you need to divide by 1000, because 1kg=1000g:
257÷1000= 0.257 Kg
The mass of the fruits in kilogram (kg) is 3.556 kg
Given:
Mass of the bag containing fruits = 3.813 kg
Mass of the empty bag = 257 g
convert
257 g to kg
257 g = 0.257 kg
Mass of the bc fruits = Mass of the bag containing fruits - Mass of the empty bag
= 3.813 kg - 0.257 kg
= 3.556 kg
Therefore, the mass of the fruits in kilogram is 3.556 kg

A tire manufacturer knows that 5% of tires contain a defect, and the presence of a defect is independent from tire to tire.
What is the probability that if 5 tires are inspected, exactly 1 has a defect?
Round to 3 decimal places.
Answer:
the answer is 0.204
Step-by-step explanation:
The probability that if 5 tires are inspected, exactly 1 has a defect is 0.204
How to determine the probability?The probability that a tire is defect is given as:
p = 5%
The required probability is then calculated using:
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]
Where:
n = 5 --- number of tires
x = 1 ---number of tires with defect
So, we have:'
[tex]P(1) = ^5C_1 * (5\%)^1 * (1 - 5\%)^{5 - 1}[/tex]
This gives
[tex]P(1) = 5 * (5\%) * (1 - 5\%)^4[/tex]
Evaluate the product
P(1) = 0.204
Hence, the probability that if 5 tires are inspected, exactly 1 has a defect is 0.204
