Answer:
B
Step-by-step explanation:
Because the height is only used once (not squared) in the cone volume formula, the volume is only multiplied by 4.
The volume of the right circular cone must be multiplied by 4.
The correct answer is option (B). 4
What is the volume of the right circular cone?[tex]V=\frac{1}{3}\times \pi \times r^{2} \times h[/tex], where 'r' is the radius of circular base and 'h' is the height of the right circular cone.
For given example,
The height of the right circular cone is multiplied by 4, but its radius remains fixed.
From the formula of the volume of the right circular cone,
[tex]V\propto h[/tex]
This means, as height of the cone increases, the volume of the cone increases at the same rate.
As the height of a right circular cone is multiplied by 4, the volume of the cone must be multiplied by factor 4.
Therefore, the correct answer is option (B). 4

Jordan fills several bags with oranges. This line plot shows the weight of each bag.
How many more pounds does one of the heaviest bags weigh than one of the lightest bags?
Enter your answer as a fraction in simplest form by filling in the boxes.
The heaviest bag has (1 + 1/8) lb more than the lightest bag.
How many more pounds does one of the heaviest bags weigh than one of the lightest bags?By looking at the histogram, we can see that the heaviest bag weighs:
M = (5 + 1/2) lb
The lightest bag weighs:
m = (4 + 3/8) lb
Now we need to take the difference between these masses:
M - m = (5 + 1/2) lb - (4 + 3/8) lb = (5 - 4) lb + (1/2 - 3/8) lb
M - m = 1 lb + (4/8 - 3/8)lb = (1 + 1/8)lb
This means that the heaviest bag has (1 + 1/8) lb more than the lightest bag.

a worker uses 450 inches of steel wire to make 300 springs of the same size. At this rate how many inches of steel wire are needed to make 1 spring?
To make 1 spring, 1.5 inches of steel wire are needed.
Explanation:To find out how many inches of steel wire are needed to make 1 spring, we can set up a proportion. We know that the worker uses 450 inches of steel wire to make 300 springs. Let x represent the number of inches of steel wire needed to make 1 spring. The proportion would be:
450 inches/300 springs = x inches/1 spring
To solve for x, we can cross multiply:
450 * 1 = 300 * x
450 = 300x
Dividing both sides by 300, we get:
x = 450/300 = 1.5 inches
Therefore, 1.5 inches of steel wire are needed to make 1 spring.

Answer:
D. 31
Step-by-step explanation:
To find the mean of any group of numbers, you simply add up all the numbers and then divide by how many numbers there are.
Using a calculator or a pencil, add the following:
27 + 28 + 30 +28 + 28 + 31 + 29 + 33 + 28 + 28 + 31 + 33 + 41 + 41 + 25
= 461
The last step is to divide 461 by 15:
461/15 = 30.73
Round 30.73 to the nearest whole number and you get D. 31

#7: At the gym on Saturday, Reese ran 5 miles on the treadmill and then
completed 1 mile on the elliptical machine, and burned 725 calories. On Sunday
she ran 3 miles on the treadmill and completed 1 mile on the elliptical, and burned
505 calories. Write and solve a linear system to find the number of calories Reese
burns on each machine.
Treadmill:
Elliptical:
Answer: The equations are 5t + e = 725 and 3t + e = 505
Step-by-step explanation: We shall start by assigning letters to the unknown variables, hence we shall call the treadmill t, and we shall call the elliptical machine e.
If on Saturday, she ran 5 miles on the treadmill and 1 mile on the elliptical machine and she burned 725 calories in the process, we can express this as
5t + e = 725 ------(1)
Also on Sunday, she ran 3 miles on the treadmill and 1 mile on the elliptical machine and burned 505 calories in the process, that too can be expressed as
3t + e = 505 ------(2)
We now have a pair of simultaneous equations which an be solved by the elimination method (reason being that on of the unknowns have the same coefficient, that is variable e).
Subtract equation (2) from equation (1) and you arrive at;
2t = 220
Divide both sides of the equation by 2
t = 110
Having calculated the value of t, substitute for the value of t into equation (1)
5t + e = 725
5(110) + e = 725
550 + e = 725
Subtract 550 from both sides of the equation
e = 175
The above calculations shows that the calories burned on each gym equipment are;
Treadmill = 110 per hour
Elliptical = 175 per hour

Answer:
(4, 0) and (6, 0)
Step-by-step explanation:
The function that we have is:
[tex]g(x)=x^2-10x+24[/tex]
This is the function of a parabola.
to find the points where the function crosses the x-axis, we need to find the values of x for which g(x) (which is the value of the y-axis) is equal to zero.
so we need [tex]g(x)=0[/tex] for the function to be crossing the x-axis.
Thus our equation becomes:
[tex]x^2-10x+24=0[/tex]
and we can solve this equation with the quadratic formula or by factoring.
I will sove by factoring:
To factor this type of equations we need to find 2 number that satisfy the following:
when multiplied result in +24 (the independent number of the equation) and when added or substracted result in -10 (the coefficient of the x in the equation)In this case those 2 number are: -6 and -4 because:
(-6)(-4)=+24
-6 - 4 = -10
Thus we arrange our factored equation as follows:
from [tex]x^2-10x+24=0[/tex] through factoring we get:
[tex](x-6)(x-4)=0[/tex]
and because of the zero factor property (if two things when multiplied result in zero one of them or both must be zero), thus our x values are:
[tex]x-6=0\\x=6\\[/tex]
and
[tex]x-4=0\\x=4[/tex]
thus, our points are those with and y coordinate of 0 and an x coordinate of 6 and 4:

11 inches of snow were predicted. 16 inches of snow fell. Calculate the percent error?
Answer : The percentage error will be, 45.5 %
Step-by-step explanation :
To calculate the percentage error, we use the equation:
[tex]\%\text{ error}=\frac{|\text{Experimental value - Accepted value}|}{\text{Accepted value}}\times 100[/tex]
We are given:
Experimental value = 16 inches
Accepted value = 11 inches
Now put all the given values in above equation, we get:
[tex]\%\text{ error}=\frac{|16-11|}{11}\times 100\\\\\%\text{ error}=45.5\%[/tex]
Hence, the percentage error will be, 45.5 %

er as a decimal rounded to
To determine how much more wire the sister used, we calculate the difference in circumference based on the increased diameter of 12 inches using the formula C = πd. The extra wire length is 3.14 • 12, which is the difference in circumference between the sister's and Poppy's wall hangings.
Explanation:The student's question focuses on comparing the length of wire used by Poppy and her sister for making metal wall hangings. Poppy's wall hangings have an unspecified radius, while her sister's hangings have a diameter that is 12 inches longer than Poppy's. The amount of wire corresponds to the circumference of the wall hangings, which can be found by using the diameter to calculate the circumference with the formula C = πd, where C is the circumference and d is the diameter.
To find out how much more wire the sister used per wall hanging than Poppy, we first determine the diameter of Poppy's hangings. Let's denote it as d, then her sister's hangings' diameter would be d + 12 inches. Using 3.14 for π, the difference in wire used would be 3.14 • (d + 12) - 3.14 • d, which simplifies to 3.14 • 12. After calculating and rounding to the nearest hundredth, we get the answer.
The output of a function or relation, or the set of y-values that a graph is defined for, is called the ___.
Answer:
Range
Step-by-step explanation:
The range of a graph tells you all of the possible y-values for it.
There is also the domain, which tells you all of the possible x-values.
For example, if you have this relation, that only has these points:
(1, 2) (2, 4) (3, 6)
Then the range is {2, 4, 6}. This means the "y" can ONLY be the numbers stated here.
The domain would be {1, 2, 3}.
