Answer:
The answer is 5.
Step-by-step explanation:
Multiplicative rate of change can be described as the rate change based on a original amount or point.
If we look at the given points for the function f(x) = 2.5x, we can see that the x coordinates increase by one while the y coordinate is increasing by 5 times it's value for the previous point.
So we can say that the multiplicative rate of change is 5 for the function f(x) = 2.5x.

A cyclist rides her bike at a rate of 9 kilometers per hour. What is the rate in kilometers per minute? How many kilometers will the cyclist travel in 2 minutes
Answer: 0.15km/min and 0.3km in 2 mins
Step-by-step explanation:
Given Data:
Cyclists speed = 9km/hr
1. Some traveling 60 km/h is traveling one km/min
60/60= 1 km/min
Rate in km/min
= 9km/hr / 60min
= 3/20 km/min
= 0.15 km/min
Kilometers travelled in 2mins
= 2 / 60
= 1 / 30
= 9km/hr * 1 / 30
= 9 / 30
= 0.3 km in 2mins
Answer:
Rate(in km/min) = 0.15 km/min
Distance traveled in 2 mins = 0.3 km
Step-by-step explanation:
Rate = 9 km/hr
1 hr = 60 mins
In 60 minutes, the cyclist rides 9 km
in 1 minute, the cyclist will ride 9/60 km
Therefore, the rate in km/min = 9/60 km/min
Rate(in km/min) = 0.15 km/min
Since the cyclist rides 0.15 km in 1 min,
In 2 mins, the cyclist will ride 0.15 * 2 km = 0.3 km
Distance traveled in 2 mins = 0.3 km

5 ?
FIND THE ?
HURRY UP I HAVE 1 MINUTE TO SOLVE THIS
Answer:
3 dogs, $15
5 dogs, $25
Step-by-step explanation:
Jane charges $5 per dog.
When she walks 3 dogs ;
1 dog = $5
3 dogs = x
x × 1 dog = $5 × 3 dogs
x= $5 × 3 dogs/ 1 dog
x= $5 × 3 = $15
When Jane Walks 5 dogs she receives,
y= $5 × 5
y= #25.
For 3 dogs, Jane would charge $15. For 5 dogs, she would charge $25. You find these amounts by multiplying the number of dogs by the charge per dog, which is $5.
Explanation:Since Jane charges $5 for each dog she walks, you can find the charge for any number of dogs by multiplying the number of dogs by 5.
For 3 dogs, she would charge $15 (3 dogs x $5 per dog = $15).
For 5 dogs, she would charge $25 (5 dogs x $5 per dog = $25).
So, the completed table would look like this:
Dogs | Charge in dollars
1 |$5
3 |$15
5 |$25

Delisa is designing a website that will be viewable on both computers and mobile devices, so the website as it is seen on a mobile device is proportional to the website as it is seen on a computer. The diagonal of Delisa's computer monitor is 21 inches, and the diagonal of Delisa's tablet is 9.1 inches. If an image is 19 centimeters wide on the website when it's displayed on Delisa's computer, how wide should the image be on the tablet? Round to the nearest tenth of a millimeter, if necessary.
Final answer:
To find the width of the image on the tablet, set up a proportion using the diagonals of the computer monitor and the tablet. Solve for the unknown width using cross multiplication.So,on tablet it would be 0.84mm.
Explanation:
To determine the width of the image on the tablet, we can use a proportion based on the diagonals of the computer monitor and the tablet. The proportion can be set up as follows:
Computer Diagonal / Tablet Diagonal = Computer Width / Tablet Width
Substituting the given values, we have:
21 inches / 9.1 inches = 19 centimeters / x
Cross multiplying and solving for x, we get:
x = (9.1 inches * 19 centimeters) / 21 inches
Converting the units, the width of the image on the tablet should be approximately 8.43 centimeters=0.84mm
A water balloon is shot into the air with an upward velocity of 95 ft/s. The balloon is released 12 feet above the ground. Write a function that represents the height h of the balloon in feet after t seconds. How long will it take the balloon to reach its maximum height? What will the maximum height be? (ALL ANSWERS SHOULD BE EXPRESSED TO THE NEAREST HUNDREDTH.)
Function: ____________________
Time to reach the maximum height: ___________________
Maximum Height: ______________________
Approximately how many whole seconds will it take to hit the ground?: _________________
Answer:
1. h = h₀ + u×t - 1/2×g×t²
2. 2.95 s
3. 152.14 ft
4. 3.07 s
Step-by-step explanation:
The given parameters are;
Vertical velocity of the balloon = 95 ft/s
Height from which the balloon is released = 12 feet
The function is h = h₀ + u×t - 1/2×g×t²
Where:
h = Height of the balloon at time t
h₀ = Initial height of the balloon = 12 feet
u = Initial upward velocity of the balloon = 95 ft/s
t = Time duration of motion
g = Acceleration due to gravity = 32.2 ft/s²
2. The time to maximum height is found from;
v = u - g·t
Where:
v = Final velocity = 0 m/s at maximum height
∴ 0 = 95 - 32.2 × t
32.2·t = 95
t = 95/32.2 = 2.95 s
Therefore, the time it will take to reach maximum height = 2.95 s
3. From h = h₀ + u×t - 1/2×g×t², we have;
h = 12 + 95×2.95 - 1/2×32.2×2.95² = 152.14 ft
4. Therefore;
152.14 = 0×t + 1/2 × 32.2 × t²
t² = 152.14/16.1 = 9.45 s
t = √9.45 = 3.07 s
Answer:
The function is: y(t) = 12 + 95*t - 16.085*t²
The time it'll take to reach the maximum height is: 2.95 s
The maximum height is: 152.27 ft
The time it'll take to hit the ground is: 12 s
Step-by-step explanation:
The water ballon is under the constant acceleration of gravity, therefore it's movement can be modelled by the equations that describe constant acceleration movement, as shown below:
y(t) = y(0) + v(0)*t - 0.5*g*t²
The acceleration is negative, because they are contrary to the movement. Applying the data form the problem, we have:
y(t) = 12 + 95*t - 0.5*32.17*t²
y(t) = 12 + 95*t - 16.085*t²
This equation describes a parabolla, therefore the time at which it achieves the maximum height is the "x" coordinate for the vertex, which can be found by using the formula below:
t = (-b)/[2*a]
t = (-95)/[2*(-16.085)] = -95/(-32.17) = 2.95 s
And the maximum height is:
y(2.95) = 12 + 95*2.95 - 16.085*(2.95)² = 152.27 ft
The time it'll take to reach the ground is:
y(0) = 12 + 95*0 - 16.085*(0)² = 12 s
to rent a building for a school dance ava paid $120 plus $2.50 for each student who attended. If she paid a total cost of $325 how many students attended the dance
Answer:
82 students
Step-by-step explanation:
The total number of students who attended the dance can be found by subtracting the initial rental cost from the total cost, and then dividing this amount by the cost per student. The number of students who attended the dance was 82.
Explanation:This problem can be solved with a little bit of algebra. The initial cost of the building was $120, and there was an additional cost of $2.50 for each student who attended. The total cost was $325. Therefore, in order to determine how many students attended the dance, you would first need to subtract the initial cost of the building from the total cost. This leaves us with $325 - $120 = $205.
Next, you would divide this amount by the cost per student. $205 ÷ $2.50 = 82.
Therefore, the number of students who attended the dance was 82.

A pizza with radius 7 in. is cut into 12 equal-sized pieces. What is the area of each piece? Round to the nearest hundredth of an inch.
Each pizza slice has an area of approximately 12.82 square inches, rounded to the nearest hundredth.
To find the area of each pizza slice, we first need to find the total area of the pizza and then divide it by the number of slices.
The formula for the area of a circle is [tex]\( A = \pi r^2 \)[/tex], where [tex]\( \pi \)[/tex] is approximately 3.14 and r is the radius of the circle.
Given that the radius of the pizza is 7 inches, we can calculate the total area of the pizza:
[tex]\[ A_{\text{total}} = \pi \times (7)^2 \]\[ A_{\text{total}} = 3.14 \times 49 \]\[ A_{\text{total}} \approx 153.86 \text{ square inches} \][/tex]
Now, to find the area of each pizza slice, we divide the total area by the number of slices (12):
[tex]\[ A_{\text{each slice}} = \frac{A_{\text{total}}}{12} \]\[ A_{\text{each slice}} \approx \frac{153.86}{12} \]\[ A_{\text{each slice}} \approx 12.82 \][/tex]
So, the area of each pizza slice is approximately 12.82 square inches.

A silo is a composite of a cylindrical tower with a cone for a roof. Find the volume of the silo if the
radius of the base is 120 feet, the height of the roof is 25 feet, and the height of the entire silo is 130
feet.
Answer:
5127079.21 cubic feet
Step-by-step explanation:
The silo is in the shape of a cylinder and a cone.
The volume of the silo will be the sum of the volumes of the cylinder and the cone.
Therefore, its volume is:
[tex]V = \pi r^2h + \frac{1}{3} \pi rH[/tex]
where r = radius of cylinder and cone
h = height of cylinder
H = height of cone
The radius of the base is 120 feet, the height of the roof (cone) is 25 feet. The height of the entire silo is 130 feet. This means that the height of the cylinder is:
130 - 25 = 105 feet
Therefore, the volume of the silo is:
[tex]V = (\pi * 120^2 * 105) + (\frac{1}{3} * 120^2 * 25)\\\\V = 4750088.09 + 376991.12\\\\V = 5127079.21 ft^3[/tex]
The volume of the silo is 5127079.21 cubic feet.
People use water to cook, clean, and drink every day. An estimate of 32.5% of the water used each day is for drinking. If a family uses 68.9 gallons of water a day for drinking, how many gallons do they use every day
Answer:
they use 212 gallons
Step-by-step explanation:
(68.9/32.5)*100
the division by 32.5 is to determine the amount of water one percent would be, so multiplying it by 100 will give you the total amount
Final answer:
To find the total daily water usage of a family using 68.9 gallons per day for drinking, which is 32.5% of their total usage, you divide the amount of water for drinking by 0.325. The calculation shows the family uses about 212 gallons of water per day.
Explanation:
The question asks us to calculate the total daily water usage of a family if they use 68.9 gallons per day for drinking, which represents 32.5% of their total daily use. To find the total water use, we divide the amount of water used for drinking by the percentage that represents drinking water.
Step-by-step Calculation:
Convert the percentage to a decimal by dividing 32.5 by 100, giving us 0.325.
Divide the gallons used for drinking by this decimal: 68.9 gallons / 0.325 = 212 gallons (rounded to the nearest whole gallon).
Therefore, the family uses approximately 212 gallons of water every day for all purposes.

Jonas practices guitar 1 hour a day for 2 years. Bradley practices the guitar 2 hours a day more than Jonas. How many more minutes does Bradley practice the guitar than Jonas over the course of 2 years?
Answer:
Bradley practice 109500 more minutes than Jonas over the course of 2 years.
Step-by-step explanation:
Jonas practices guitar 1 hour a day for 2 years.
1 year = 365 days
2 years = [tex]365 \times 2 = 730 days[/tex]
1 hour = 60 minutes
So, Jonas practice for 60 minutes in 1 day
Jonas practice for minutes in 365 days =[tex]365 \times 60 =21900 minutes[/tex]
Bradley practices the guitar 2 hours a day more than Jonas.
So, Bradley practice the guitar for hours per day = 2+1=3 hours
3 hours = 3 \times 60 = 180 minutes
Bardley practice for minutes per day = 180 minutes
Bardley practice for minutes for 730 days = [tex]180 \times 730 =131400 minutes[/tex]
Difference in minutes in 2 years = 131400-21900=109500 minutes
Hence Bradley practice 109500 more minutes than Jonas over the course of 2 years.

Step-by-step explanation:
17, 22, 34, 3, 16, 16, 24, 55, 18, 3, 16, 12, and 18
First put the numbers in order from smallest to largest
3, 3, 12, 16, 16, 16,17,18, 18,22,24, 34, 55
The mean is where you add up all the numbers and divide by the number of numbers
(3+ 3+ 12+ 16+ 16+ 16+17+18+ 18+22+24+ 34+ 55)/13
254/13
19.53846154
mean = 19.54
The median is the middle number
Since there are 13 numbers the middle number is 13/2 = 6.5 which rounds to 7
The 7th number is 17
median = 17
Mode is the number that appears most often
16 appears 3 times which is more often than any other number
mode 16
The range is the largest number minus the smallest number
55-3 = 52
range = 52
If a sphere’s surface area is doubled, what is the corresponding change in radius?
Answer:
The radius has an increase of 41.4%
Step-by-step explanation:
We have that the surface area formula is equal to:
a = 4 * pi * r ^ 2
in this case if you assume an area of 100 and we calculate the radius it would be:
100 = 4 * pi * r ^ 2
we solve for r:
r ^ 2 = 100/4 * pi
r ^ 2 = 100 / (4 * 3.14)
r ^ 2 = 7.9617
r = 2,822
now if we double the area, that is 200:
r ^ 2 = 200 / (4 * 3.14)
r ^ 2 = 15.9236
r = 3,990
So the change of the radius would be:
3.99 / 2,822 = 1,414
That is to say that the radius has an increase of 41.4%

A = final amount
P = initial principal balance
r = annual interest rate
t = time (in years)
and the interest is going to be 750 after you plug it in, they are not asking for the amount of money total, but the amount of interest earned.
3 percent simple interest for 5 years means you are getting 0.03 percent of money from the 5,000 initial value and for 5 years. The total interest is $750.
