a) He will earn $584 for working 36 hours.

b) He will earn $656 for working 39 hours.

c) He will earn $728 for working 42 hours.

Step-by-step explanation:

Amount per hour = $16

Time and a half means 1.5 times more than the original payment.

Therefore, above 35 hours, the earning for one hour,

Extra time per hour = 16*1.5 = $24

A) 36 h

For the first 35 hours, he will get $16 per hour, therefore,

Amount of 35 hours = [tex]35*16= \$560[/tex]

Amount of one hour = $24 (as calculated above)

Total = 560+24 = $584

He will earn $584 for working 36 hours.

B) 39 h

39 h = 35h + 4h

Amount of 35 hours = $560

Amount of extra 4 hours = $24*4 = $96

Total = 560+72 = $656

He will earn $656 for working 39 hours.

C) 42 h

42 h = 35h + 7h

Amount of 35 hours = $560

Amount of extra 7 hours = 24*7 = $168

Total = 560+168 = $728

He will earn $728 for working 42 hours.

You subtract 33 and 15

The system of equations are p = 150 + 5n and p = 15n

Solution:

Given that, The Parks and recreation department in your town offers a season pass for $150.  

With the season pass you pay $5 per session to use the town's tennis courts.  

Without the season pass you pay $15 per session to use the tennis courts.

We have to write a system of equations to represent the situation

Now, let the number of sessions be "n" and total paying amount be "p"

Then in case of taking season pass  

total amount = season pass cost + $5 per session

p = 150 + 5 x n  

p = 150 + 5n  

And in case of no season pass

total amount = 15 per session

p = 15 x n  

p  = 15n

Hence, the system of equations are p = 150 + 5n and p = 15n

Final answer:

To represent the cost of using the town's tennis courts with and without a season pass, we use two equations: C = 150 + 5x for with a pass, and C = 15x for without a pass, where C is the total cost and x is the number of sessions.

Explanation:

The Parks and Recreation Department offers two options for using the town's tennis courts: with a season pass and without a season pass. We need to write a system of equations to represent the cost for each option depending on the number of sessions a person attends.

Equations

With Season Pass: C = 150 + 5x

Without Season Pass: C = 15x

In these equations, C represents the total cost of using the tennis courts for a given number of x sessions. For the pass option, there is an upfront cost of $150 plus $5 per session. Without the pass, each session costs $15.

These equations can help determine the point at which purchasing a season pass becomes more cost-effective than paying per session.

She bought 54 child tickets and 19 adult tickets.

Step-by-step explanation:

No. of tickets purchased = 73

Cost of tickets = $771

Cost of one child ticket = $9

Cost of one adult ticket = $15

Let,

Child ticket = x

Adult ticket = y

According to given statement;

x+y=73   Eqn 1

9x+15y=771   Eqn 2

Final answer:

Anna bought 54 children's tickets at $9 each and 19 adult tickets at $15 each to spend a total of $771 for a field trip to the zoo.

Explanation:

The question is asking us to solve a system of linear equations to find out how many children's and adult's tickets were purchased for a zoo field trip. The total cost of the tickets was $771, with children's tickets costing $9 each and adult's tickets costing $15 each. Anna purchased a total of 73 tickets.

Let's define two variables, C for the number of children's tickets, and A for the number of adult tickets. We have two equations based on the information given:

9C + 15A = 771 (Total cost equation)

C + A = 73 (Total number of tickets equation)

To solve this system, we can use substitution or elimination. Here's how you might solve it using substitution:

From the second equation, we express one variable in terms of the other: A = 73 - C.

Substitute A in the first equation: 9C + 15(73 - C) = 771.

Simplify and solve for C: 9C + 1095 - 15C = 771, which simplifies to -6C = -324, so C = 54.

Use the value of C to find A: A = 73 - 54, so A = 19.

Anna bought 54 children's tickets and 19 adult tickets.

The width and length of the rectangle are 7 meters and 10 meters, respectively, as determined by using algebraic expressions to relate the given perimeter with the width and length formulas.

To solve for the length and width of a rectangle given the perimeter, we can use algebra. Since we know the length (L) is 4 meters less than twice the width (W), we can write this relationship as L = 2W - 4. The formula for the perimeter (P) of a rectangular shape is P = 2L + 2W. We are given that the perimeter is 34 meters.

Substituting the expression for L into the perimeter formula gives us:

Since the perimeter is 34 meters, we set 6W - 8 = 34.

Now, we find the length using the expression L = 2W - 4:

Therefore, the width is 7 meters and the length is 10 meters.

Step-by-step explanation: The common denominator will be the least common multiple for the two denominators.

To find the least common multiple or lcm of 3 and 9, begin by listing the first few multiples for each number.

Multiples of 6

1 × 9 = 9

2 × 9 = 18

3 × 9 = 27

Notice that we skipped 0 × 9 in our list of multiples. That's because 0 × 6 is 0 according to the zero property of multiplication and our least common multiple can't be 0.

When listing the multiples of 3, it's a good idea to keep an eye on the list of multiples for 9 so that we will notice when we find a least common multiple.

Multiples of 3

1 × 3 = 3

2 × 3 = 6

3 × 3 = 9

Notice that in both lists, we have the least common multiple which is 9.

Therefore, the least common denominator of 9 and 3 is 9.

The starting point is (0 , 210) and the rate of change is 1.12

Step-by-step explanation:

The form of the exponential function is [tex]f(x)=a(b)^{x}[/tex] , where

∵ The function is [tex]a(x)=210(1.12)^{x}[/tex]

∵ At the starting point x = 0

- Substitute x in the function by 0

∴ [tex]a(0)=210(1.12)^{0}[/tex]

- Remember any number to power of zero = 1 except 0

∴ [tex](1.12)^{0}=1[/tex]

∴ a(0) = 210(1) = 210

∵ a(x) = y

∴ The starting point is (0 , 210)

∵ The from of the exponential equation is [tex]f(x)=a(b)^{x}[/tex]

∵ [tex]a(x)=210(1.12)^{x}[/tex]

- Compare the two function

∴ b = 1.12

∵ b is the rate of change of the function

∴ The rate of change of the function is 1.12

The starting point is (0 , 210) and the rate of change is 1.12

Answer:

212.9 days

Step-by-step explanation:

The bacteria culture initial population is 25 represented by Po and the population after t days is represented by P(t).

Using growth formula:

P(t) = Po ( 1 + r)^t where r is rate in percent and t is time in days

r = 1.28%, P(t) = 375, and Po = 25

substituting this values into the equation above yields

375 = 25 (1 + 1.28/100)^t

375÷25 = ( 1 + 0.0128)^t

15 = (1.0128)^t

take logarithm of both sides

log 15 = log (1.0128)^t remember the law log a^b = b log a

applying the same law gives

log 15 = t log 1.0128

divide both side by log 1.0128

log 15 ÷ log 1.0128 = t log 1.0128 ÷ log 1.0128

Final answer:

To find the length and width of a rectangle with a given perimeter, use algebra to solve for the width first, then use that value to find the length. The width is 5 meters and the length is 18 meters based on the given perimeter and the relationship between length and width.

Explanation:

The perimeter of a rectangle is given by the formula P = 2l + 2w, where P is the perimeter, l is the length and w is the width. According to the problem, the perimeter is 46 meters, and the length is 3 meters more than 3 times the width. Therefore, we can express the length as l = 3w + 3. Let's set up the equation using the perimeter formula:

Now that we've found the width to be 5 meters, we can find the length:

The width of the rectangle is 5 meters and the length is 18 meters.

Answer:

Neighborhoods that sheriff patrol in 5/8 of an hour is 3.125.

Step-by-step explanation:

The Time taken to patrol an entire neighborhood   = 3/ 15 hour

Total amount of time, the Sheriff  has to do patrolling = 5/ 8 of an hour.

Now, let us assume the total neighborhoods paroled in the given time  = m

So, [tex]\textrm{ Number of neighborhoods patrolled}  = \frac{\textrm{Total available time}}{\textrm{Time used in 1 paroling 1 neighborhood}}[/tex]

[tex]m = \frac{\frac{5}{8} }{\frac{3}{15} }   = {\frac{5}{8} \times {\frac{15}{3}  =3.125[/tex]

or, the number of neighborhoods covered  = 3.125

Hence, neighborhoods that sheriff patrol in 5/8 of an hour is 3.125.

To find out how many neighborhoods the sheriff can patrol in 5/8 of an hour, divide 5/8 by 3/15, which simplifies to 1/5. The calculation gives us 3.125, meaning the sheriff can complete 3 full neighborhood patrols.

The question involves determining how many neighborhoods a sheriff can patrol in 5/8 of an hour if it takes 3/15 of an hour to patrol one neighborhood. To solve this, we divide the total time available by the time it takes to patrol one neighborhood.

Thus, the sheriff can patrol 3 full neighborhoods in 5/8 of an hour, with some additional time remaining that is not enough to complete a fourth patrol.

The coordinates of triangle ABC after translation according to given rule are:

A'(0,-2), B'(-1,-10) and C'(6,-4)

Step-by-step explanation:

Given vertices are:

A(-2, 1), B(-3, -7) and C(4, -1)

The translation rule is: (x,y) => (x+2, y-3)

In order to translate the vertices, 2 will be added to x-coordinate and 3 will be subtracted from y-coordinate

So,

A(-2, 1) =>  A' (-2+2, 1-3) => A'(0,-2)

B(-3,-7) = > B'(-3+2, -7-3) => B'(-1, -10)

C(4,-1) => C'(4+2, -1-3) => C' (6, -4)

Where

F is the future amount

P is the present (initial) amount

r is the rate of growth, in decimal

t is the time in years

Given,

P = 20,000

r = 8% = 8/100 = 0.08

F = double of initial amount = 2 * 20,000 = 40,000

We need to find t:

[tex]F=P(1+r)^t\\40,000=20,000(1+0.08)^t\\2=(1.08)^t[/tex]

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two complex numbers (a+bi) and (c+di) points is equal to

[tex](\frac{a+c}{2})+(\frac{b+d}{2})i[/tex]

we have

(1+9i) and (5-3i)

substitute the given values

[tex](\frac{1+5}{2})+(\frac{9-3}{2})i[/tex]

[tex]3+3i[/tex]

Final answer:

The midpoint of the complex numbers 1+9i and 5-3i is calculated using the average of their real and imaginary parts, resulting in the midpoint of 3 + 3i.

Explanation:

To find the midpoint of two complex numbers, 1+9i and 5-3i, we use the midpoint formula for complex numbers which is the average of the real parts and the average of the imaginary parts separately. The formula for the midpoint M is given by:

M = ½(x1 + x2) + ½(y1 + y2)i

For our complex numbers, the real parts are 1 and 5, and the imaginary parts are 9 and -3. Applying the midpoint formula, we get:

M = ½(1 + 5) + ½(9 - 3)i = ½(6) + ½(6)i = 3 + 3i

Therefore, the midpoint of the complex numbers 1+9i and 5-3i is 3 + 3i.
