Stefan’s family rented a rototiller to prepare an area in their backyard for spring planting. The rental company charged an initial fee of $43 with an additional fee per hour. If they paid $64 after renting the rototiller for 7 hours, what was the hourly fee?
If h represents the hourly fee, which equation models this problem?
What was the hourly fee for the rototiller?
The hourly fee is $3.00 per hour.
It is required to find the hourly fee for the rototiller.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
Let h represents the hourly fee.
Let C be the total charge and t be the rental time in hours.
C = ht + 43
Putting the given values into the equation, we get:
64 = 7h + 43
7h = 21
h = 3
Therefore, the hourly fee is $3.00 per hour.

Seventeen lines drawn in a plane, with no three concurrent and no two parallel, divide the plane into
closed regions (bounded on all sides) and open regions. The number of closed regions is
Answer:
120
Step-by-step explanation:
Make a chart:
Lines: 0 1 2 3 4 5 6
Closed regions: 0 0 0 1 3 6 10
Find the number of numbers using the formula:
[tex]\frac{first term + last term}{2}[/tex] x 14 = [tex]\frac{2 + 15}{2}[/tex] x 14
= 8.5 x 14
= 119
119 + 1 = 120
(add 1 because we didn't count the first line in the formula)
I hope this helps :)
The total number of closed regions is 120.
Given that,
Seventeen lines are drawn in a plane, with no three concurrent and no two parallel, dividing the plane into closed regions (bounded on all sides) and open regions.
Used the formula to calculate the number of closed regions with n sides is,
Number of sides = (n - 1) (n - 2) / 2
Here, n = 17
Hence, The number of closed regions is,
Number of sides = (n - 1) (n - 2) / 2
Number of sides = (17 - 1) (17 - 2) / 2
Number of sides = 16 × 15 / 2
Number of sides = 120

What is a strategy for dividing 428 by 107?
Answer:
4Step-by-step explanation:
428÷107
Use the 1 st
digit 4 from dividend 428
107)1
107)428
Since 4 is less than 107, use the next digit 2 from dividend 428 and add 0 to the quotient
107)02
107)428
Use the 2nd
digit 2 from dividend 428
107)03
107)428
Since 42 is less than 107, use the next digit 8 from dividend 428 and add 0 to the quotient
107)004
107)428
Use the 3rd
digit 8 from dividend 428
107)005
107)428
Find closest multiple of 107 to 428. We see that 4×107=428 is the nearest. Now subtract 428 from 428 to get reminder 0. Add 4 to quotient.
107)0046
107)428
107)428
107)9990
Since 0 is less than 107, stop the division. The reminder is 0. The topmost line 004 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 4.
Quotient: 4
Reminder: 0

Given g(x)=-2x-1g(x)=−2x−1, find g(-4)g(−4)
Answer:
7
Step-by-step explanation:
The function f is defined by g(x) = -2x-1. so the function defined as g (-4) will be equal to g (-4) = 7.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
The function f is defined by g(x)=−2x−1
We need to find the function defined as g(-4).
Then substitute;
g(x)=−2x−1
g(-4 ) =−2 (-4) − 1
g(-4 ) = 8 -1
g(-4 ) = 7
Therefore, The function f is defined by g(x) = -2x-1. so the function defined as g (-4) will be equal to g (-4) = 7.

Answer:
1) x= -8
2) x=7
Step-by-step explanation:
1) x+88+x+108 = 180 ( co-interior angles)
=> 2x+ 196 = 180
=> 2x= 180-196
=> 2x= -16
=>x= -16/2
=>x= -8

Answer:
x = 41
y = 65
z = 107
Step-by-step explanation:
y and 65 are vertically opposite angles. Vertically opposite angles are equal.
y = 65
74 + y + x = 180
74 + 65 + x = 180
139 + x = 180
x = 180 - 139
x = 41
z is the exterior angle, whereas 66 and x are interior angles in a triangle.
Formula : -
Exterior angle = Sum of two interior angles
z = 66 + x
= 66 + 41
z = 107

The Candela brothers own two pizza restaurants, one on Park Street and one on Bridge Road.
The computer output below summarizes the distribution of weekly revenues at each

The mean, median and mode are measures of central tendency, that is they tend to indicate the location middle of the data
Required values;
(a) The performance for the week for Park Street
Revenue is Q₂ < $7,500 < Q₃The sales for the week is better than 72.91% of all salesThe performance for the week for Bridge Road
Revenue; Q₂ < $7,100 < Q₃The sale for the week is better than 59.87% of all sales(b) The mean is $3611
The median is $3,600
The standard deviation is $3250
The Interquartile range is $6075
Reason:
The table of values that maybe used to find a solution to the question is given as follows;

(a) Park Street revenue = $7,500
Bridge Road's revenue = $7,100
The two stores sold close to but below the 75th percentile
Bridge Road revenue;
The z-score is given as follows;
[tex]Z = \dfrac{x - \mu }{\sigma }[/tex]
[tex]Z = \dfrac{7100 - 5,989 }{1794 } \approx 0.6193[/tex]From the Z-Table, we have;
The percentile= 0.7291
Therefore, the sale for the week for Park Street is better than 72.91% of all the salesPark Street revenue;
The z-score is given as follows;
[tex]Z = \dfrac{7500 - 6611}{3580} \approx 0.25[/tex]From the Z-Table, we have;
The percentile = 0.5987
Therefore, the sale for the week is better than 59.87 % of all the sales(b) Given that the operating cost is $3,000, frim which we have;
The subtracted value is subtracted from the mean and median to find the new value
Profit = The revenue - Cost
New mean = 6611 - 3000 = 3611
The new mean = $3,611The new median = 6600 - 3000 = 3600
The new median = $3,600The standard deviation and the interquartile range remain the same, therefore, we have;

How might the crisis in biodiversity lead to a food crisis for humans?
Answer:
Hi and heres your answer!
Step-by-step explanation:
The crisis of biodiversity will lead to a food crisis for humans because:
1.No varieties in certain foods like plants and animals that are healthy
2.The Less food there is,more animals go extinct which means humans will go extinct too.
and finally 3: Without certain types of species like the bee, humans have no chance of survival (since bees pollinate flowers,fruits,and plants which could be used for human consumption and medicine)
