Answer:
The cost of the 20 fruit cup is $ 60 .
Step-by-step explanation:
Given as :
The total students for fruit cup party = 18
The total teachers for fruit cup party = 2
The cost of each fruit cup =$ 3
The delivery charge = $ 10
So, The total number of people for party = Total number of student + Total number of teachers
Or , The total number of people for party = 18 + 2 = 20
∵ each fruit cup cost $ 3
∴ The cost of 20 fruit cup = $ 3 × 20
I.e The cost of 20 fruit cup = $ 60
Hence The cost of the 20 fruit cup is $ 60 . Answer
The range of the function for the fruit-cup party is $10 to $70, including the delivery charge and the cost of the fruit cups.
Explanation:To find the range of the function for the fruit-cup party, we need to consider the total cost of the fruit cups and the delivery charge. The delivery charge is a fixed cost of $10. The cost of each fruit cup is $3. So, the total cost of the fruit cups for the 18 students and 2 teachers is (18 + 2) × $3 = $60. Therefore, the range of the function is $10 to $70, which includes the delivery charge and the total cost of the fruit cups.

A bacteria culture has an initial population of 25. This bacteria reproduces at a daily rate of 1.28 percent. How long will it take for the population to grow to 375 bacteria?
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
t = 212.9 days

- 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]

Answer:
The needed line equation is : x + y + 2 = 0
Step-by-step explanation:
The slope m of the given line equation = -1
The points through which the line passes is (1,-3).
Now,as we know:
The POINT SLOPE form of the equation with point (x0,y0) is given as:
y - y0 = m (x-x0)
So, the equation if line q=with m = -1 and (x0,y0) = (1,-3) is given as
y - (-3) = -1( x - 1)
or, y + 3 = 1 -x
or, x + y + 2 = 0

A price was first decreased by 12%, then it was decreased again by an additional 5%. What is the percent of the total decrease?
Answer:
The answer is 16.4%
Step-by-step explanation:
The total decrease of price percentage is 16.4% when the price was decreased by 12% .
Evaluating decrease price :
The first discount reduces the price to (100 - 12)%
= 88% which is 0.88 times the original price.
The second discount reduces the already discounted price to
(100 - 5)% =
95% of the discounted price
(0.95 times the discounted price). Get 2 discounts combined
Final Price = (0.95)(0.88) x (Original Price)
= 0.836 x (Original Price)
This is 83.6% of the original price, so the total discount rate is
(100 - 83.6)%
= 16.4%.
Least common denominator of 7/9 and 2/3
Answer: 9
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.
Stephen invests $2,000 in a savings account paying 6% annual interest. Find the balance after 5 years if the interest is compounded quarterly.
Final answer:
The balance in the savings account after 5 years, with quarterly compounded interest, will be $2,699.80.
Explanation:
To find the balance after 5 years when the interest is compounded quarterly, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^(nt)[/tex]
Where:
- A is the final amount
- P is the principal amount (initial investment)
- r is the annual interest rate (in decimal form)
- n is the number of times the interest is compounded per year
- t is the number of years
Plugging in the given values:
[tex]A = $2,000(1 + 0.06/4)^(4*5)[/tex]
[tex]A = $2,000(1.015)^20[/tex]
A = $2,000 * 1.3499
A ≈ $2,699.80
After 5 years, the balance in the savings account will be approximately $2,699.80.
6. Leo earns $16/h as a gardener in a city
park. For time worked above 35 h in a
week, he earns time-and-a-half. How much
does he earn for each of the following
numbers of hours worked in a week?
a) 36 h b) 39 h c) 42 h
h
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.

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.

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.
Write a system of equations to represent the situation
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.
the length of a rectangle is 4 meters less than twice the width the perimeter is 34 Meters find the length and width in meters
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.
Explanation: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:
P = 2(2W - 4) + 2WP = 4W - 8 + 2WP = 6W - 8Since the perimeter is 34 meters, we set 6W - 8 = 34.
Add 8 to both sides: 6W = 42Divide by 6: W = 7 metersNow, we find the length using the expression L = 2W - 4:
L = 2(7) - 4L = 14 - 4L = 10 metersTherefore, the width is 7 meters and the length is 10 meters.
