Answer:
Volume of sphere A = 128x (Approx.)
Step-by-step explanation:
Given:
Radius of sphere A = 2 x Radius of sphere B
Volume of sphere B = 16x
Find:
Volume of sphere A
Computation:
Volume of sphere = (4/3)(π)(r)³
Volume of sphere B = (4/3)(π)(r)³
16x = (4/3)(π)(r)³
16x = (4/3)(22/7)(r)³
16x = (88/21)(r)³
Radius of sphere B = 1.56∛x Approx.
Radius of sphere A = 2 x Radius of sphere B
Radius of sphere A = 2 x 1.56∛x
Radius of sphere A = 3.12∛x Approx.
Volume of sphere A = (4/3)(π)(r)³
Volume of sphere A = (4/3)(22/7)(3.12∛x)³
Volume of sphere A = (88/21)(30.37∛x)
Volume of sphere A = 127.27x
Volume of sphere A = 128x (Approx.)

Answer:
t = 0.0475p
Step-by-step explanation:
From the options provided, the answer would be ...
t = 0.0475p
Lets say Tonia's paycheck is 25,000 she needs to pay 5% of this to her 401k, meaning she should have 95% left
25,000 * 0.95 = 23,750
Now, 5% of this remainder goes to income tax which would be...
23,750 * 0.05 = 1,187.5
Now if we use the formula and plug in 25,000 for p which is Tonia's paycheck we see that we get the same income tax amount. Therefore, we know it is the correct formula.
t = 0.0475 * 25000
t = 1,187.5

What are the solutions of the equation?
y=-7(x-3)(x+4)
Answer:
{-4, 3}
Step-by-step explanation:
To find "solutions," you must set this function equal to zero:
y = -7(x - 3)(x + 4) = 0
and then set each factor equal to 0 separately and solve each resulting equation for x:
x - 3 = 0 yields x = 3, and
x + 4 = 0 yields x = -4
Write the equation in point-slope form of the line that passes through the given point and has the given slope: (-2, -1); m=-3
Answer:
y+1=-3(x+2)
Step-by-step explanation:
point-slope form is the formula y-y1=m(x-x1), where (x1, y1) is a point and m is the slope
we are given a point (-2, -1) and a slope of -3
all we really need to do is substitute the given into the formula
remember: since the formula gives subtraction, we're going to be subtracting, even though we have negative numbers
substitute -2 as x, -1 as y and -3 as m
y--1=-3(x--2)
we can simplify this equation:
y+1=-3(x+2)

A firework rocket consists of a cone stacked on top of a cylinder, where the radii of the cone and the cylinder are equal. The diameter of the cylindrical base of the rocket is 8 in and the height of the cylinder is 5 in, while the height of the cone is 3 in. Calculate the surface area of the rocket. Leave your answer in terms of π.
Answer:
188π in^2
Step-by-step explanation:
Surface area of the rocket = surface area of the cone + surface area of the cylinder
Surface area of a cone = πr(r+h^2+r^2)
r = 8/2 = 4 in
4π( 4 + 3^2 + 4^2) =
4π ( 4 + 9 + 16) = 116π in^2
Surface area of a cylinder = 2πrh+2πr^2
(2 x n x 4 x 5) + (2 x n x 16)= 72π in^2
116 + 72 = 188π in^2

Answer:
C. The scale factor is less than one.
Step-by-step explanation:
By definition, similar triangles have equal angles and proportional corresponding side lengths. Thus, A, B, and D are all mutually exclusive, leaving C the only possible answer. Upon further inspection, the scale factor is indeed greater than one (each side length is scaled by a factor of two, which is large than one)
That's population of turtles in a lake is estimated at 1,000. The population projected to increase 12% per year.
Answer:
(1,000 * (100 + 12))/100 = 1,120 - 1,000 = 120 turtles/ per year
Step-by-step explanation:
The exponential function which can be use to identify the monthly growth is,
⇒ y = 1000 (1.12)¹²ⁿ
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
We have to given that;
That's population of turtles in a lake is estimated at 1,000.
And, The population projected to increase 12% per year.
Hence, The exponential function which can be use to identify the monthly growth is,
⇒ y = 1000 (1 + 12/100)¹²ⁿ
⇒ y = 1000 (1 + 0.12)¹²ⁿ
⇒ y = 1000 (1.12)¹²ⁿ
Thus, The exponential function which can be use to identify the monthly growth is,
⇒ y = 1000 (1.12)¹²ⁿ

Find the area of the field.
If L | | m and m<8 = 109°, what is m<5
Answer:
m∡5 = 71°
Step-by-step explanation:
m∡8 = m∡6
m∡6 + m∡5 = 180
180 - m∡6 = m∡5
180 - 109 = 71
Answer:
the measurement of angle 5 is 71
Step-by-step explanation:
m∡8 = m∡6
M∡6 + m∡5 = 180
180 - m∡6 = m∡5
180 - 109 = 71

Help find the value of x pls I’ll give brainleist. No links or I’ll report you
Answer:
x = 12
Step-by-step explanation:
The angles are supplementary and add up to 180
(8x - 20) + (8x + 8) = 180
Combine like terms
16x - 12 = 180
add 12 to both sides
16x = 192
Divide both sides by16
x = 12
Find the mode, median, mean and range for this set of data.
Number of Hours Slept: 8.5, 7,6.75,5.75, 8.75,6.25,7,7.5, 4.25
Central Tendency is the statistical measure that can be used to represent all the distribution or a dataset using a single value. The most common measures of central tendency are the mode, median, and mean.
How to determine this
Mode is the value that has the highest frequency in a given data set.
So,
8.75 the highest frequency in the data set
Mode = 8.75
Median is the middle of a sorted list of numbers when arranged in ascending order.
So,
4.25, 5.75, 6.25, 6.75, 7, 7, 7.5, 8.5, 8.75 in ascending order
Median = 7
Mean is the average or the most common value in a given set of values.
Mean = 8.5 + 7 + 6.75 + 5.75 + 8.75 + 6.25 + 7 + 7.5 + 4.25/9
Mean = 61.75/9
Mean = 6.8611
Mean = 6.86 to 2 decimal place
Range is the difference between the highest value and lowest values.
Range = Maximum value - Minimum value
Range = 8.75 - 4.25
Range = 4.5

the conjunction, x<3 and x>-1, may be written -1
===========================================================
Explanation:
The first thing to do is to swap the positions of the x < 3 and the x > -1
So you'll end up with x > -1 and x < 3
Now focus entirely on x > -1. Swap the left and right sides, and also swap the inequality sign. So we end up with -1 < x
That means the "x > -1 and x < 3" is the same as "-1 < x and x < 3"
From here, we collapse the two inequalities to form the compound inequality -1 < x < 3
We can say "x is between -1 and 3, excluding either endpoint".

To find the slope of a line, we uses y2-y1/x2-x1:
y2-y1/x2-x1
1-1/7+2
0/9
0
The slope of the line is 0.
If u have any questions about what I did feel free to ask in the comments!
Answer:
Slope = 0
Step-by-step explanation:
Formula of finding the slope: (y₂ - y₁) / (x₂ - x₁)
=> So we can say:
(-2, 1) = (x₁, y₁)
(7, 1) = (x₂, y₂)
=> (1 - 1) / (7 - (-2))
=> (0) / (9)
=> 0
Slope of this line = 0
