What is the approximate radius of a sphere with a volume of 3052 cm3?
A. 27 cm
o
B. 18 cm
C. 54 cm
D. 9 cm
SUBMIT
Answer:
D. 9 cm
Step-by-step explanation:
The radius of the sphere can be found by solving the volume equation for the radius.
V = 4/3πr³
3V/(4π) = r³
r = ∛(3V/(4π)) = ∛(3×3052/(4×π)) ≈ ∛728.611
r ≈ 9.0 cm
The radius of the sphere is about 9 cm.
Suppose t and u are linear transformations from to such that t(ux)x for all x in. Is it true that u(tx)x for all x in ? why or why not?.
A linear transformation is used to illustrate a linear operator
It is true that U(T(x)) = x for all values of x
How to determine if the linear transformation is trueThe linear functions are given as:
U(x1) and U(x2)
Given that the function U(x) is a one-one-one function, then we have:
T(U(x1)) = T(U(x2))
This becomes
x1 = x2
The above equations mean that the function U is invertible
So, we have:
S(U(x)) = U(S(x)) = x for all values of x
Also, we have:
T(U(x)) = x for all values of x.
This means that,
T(x) = S(x) and U(T(x)) = x for all values of x, because U(S(x)) = x for all values of x
Hence, it is true that U(T(x)) = x for all values of x

Element X decays radioactively with a half life of 9 minutes. If there are 890 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 238 grams?
Answer:
13.18651685
13.9
Explain:
890-238=652
652/890=0.7325842697 (Find out the percentage)
We know that 1 gram of Element X will be fully decayed in 18 minutes and half of it in 9 minutes.
0.7325842697x18=13.18651685
As you see 18/13.18651685 will equal to 18 (not exactly since it is rounded)
And of course we need to round it to nearest tenth. So the answer would be 13.9!
The time taken for the element to decay to 238 grams is 13.9 minutes.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that element X decays radioactively with a half-life of 9 minutes. If there are 890 grams of Element X,
The time taken will be calculated as,
890-238=652
652/890=0.7325842697 (Find out the percentage)
We know that 1 gram of Element X will be fully decayed in 18 minutes and half of it in 9 minutes.
0.7325842697x18=13.18651685

Sipho and Litha are brothers. The sum of their ages is 29. In 6 years' time Sipho will be the same age as Litha was 3 years ago. Determine the current age of the two brothers. Let x be the age of Sipho. 0 Copy and complete the table below: Current 3 Years Ago In 6 Years Sipho Litha Write down an appropriate equation in order to determine x. Solve for x and write down the age of Sipho and Litha
Answer: See below
Step-by-step explanation:
Let s represent Sipho's age and let l represent Litha's age
The sum of their ages is 29 years
s + l = 29...(1)
In 6 years time, Sipho (s+6), will be the same age Litha was 3 years ago (l-3)
(s+6) = (l-3)...(2)
Age:
s + l = 29
s = 29 - d (express c in d)
(29-s+6) = s - 3 (substitute c)
s+(29-s+6) = s+(d-3)
29+6 = 2s -3
29+6+3 = 2s
38 = 2s
19 = s
Back to (1):
l = 29 - 19
l = 10
Therefore, Sipho is currently 19 years old and Litha is 10 years old
The current age for the two brothers, Sipho and Litha is 10 years old and 19 years old respectively.
What is linear equation?A linear equation is the equation in which the highest power of the unknown variable is one.
To solve this problem, let's make the linear equations by the given statement.
Let x be the age of Sipho and y is the age of Litha. The sum of their ages is 29. Therefore,
[tex]x+y=29\\y=29-x[/tex]
Thus, the age of Litha is (29-x)
In 6 years' time, Sipho will be the same age as Litha was 3 years ago. Therefore,
[tex]x+6=(29-x)-3\\x+6=29-x-3\\x+x=29-3-6\\2x=20\\x=\dfrac{20}{2}\\x=10[/tex]
Thus, the age of Sipho is 10 years. The age of Litha is,
[tex]y=29-10\\y=19[/tex]
Hence, the current age for the two brothers, Sipho and Litha is 10 years old and 19 years old respectively.

Answer:
volume: 49280 cm³ and curved S.A = 5826.64 cm²
Explanation:
height of smaller cone: h₂radius of smaller cone: 7height of bigger cone: 45 + h₂radius of bigger cone: 28using similarities:
[tex]\sf \frac{45 + h2}{28} = \frac{h2}{7}[/tex]
[tex]\sf 315 + 7h2 = 28h2[/tex]
[tex]\sf 315 = 28h2-7h2[/tex]
[tex]\sf 315 = 21h2[/tex]
[tex]\sf 15 = h2[/tex]
total height of the cone: 45 + 15 = 60 cm
solve for volume:
[tex]\sf volume \ of \ cone \ = \frac{1}{3} \pi r^2 h[/tex]
[tex]\sf volume \ of \ cone \ = \frac{1}{3} \pi (28)^2 (60)[/tex]
[tex]\sf volume \ of \ cone \ = 15680\ *\frac{22}{7}[/tex]
[tex]\sf volume \ of \ cone \ = 49280 \ cm^3[/tex]
First find the slant height using Pythagoras theorem -
[tex]\sf l^2 = r^2 + h^2[/tex]
[tex]\sf l =\sqrt{ r^2 + h^2}[/tex]
[tex]\sf l =\sqrt{ (28)^2 + (60)^2}[/tex]
[tex]\sf l =66.212 \ cm[/tex]
solve for curved surface area:
[tex]\sf curved \ surface \ area = \pi rl[/tex]
[tex]\sf curved \ surface \ area = \pi (28)(66.2)[/tex]
[tex]\sf curved \ surface \ area =5826.64 \ cm^2[/tex]

[tex]\sf{- x =22-\frac{2}{5}y}[/tex]
[tex]x =-22+\frac{2}{5}y}[/tex]

[tex]\sf{3 (-22+\frac{2}{5}y) +\frac{1}{4} y=-\frac{3}{4} }[/tex]
[tex]\sf-66 +\frac{6}{5} y+\frac{1}{4} y = -\frac{3}{4}[/tex]
[tex]\sf 1.45y = 65.25[/tex]
[tex]\sf y=45[/tex]
then x will be:

if your doing a stem and leaf plot with decimals and whole numbers, would the decimals be greater than or less than the whole numbers?
(will mark brainliest if you answer)
Let's say we had this data set
1212.71313.113.51414.9This is a collection of whole numbers and decimal values. We need to standardize everything so every value is the same length exactly. Something like "12" involves 2 digits while "12.7" involves 3 digits. We can rewrite 12 into 12.0 to standardize everything to 3 digits. Same goes for 13 into 13.0 and 14 into 14.0
This is the new updated list
12.012.713.013.113.514.014.9Everything now has a decimal point and involves exactly 3 digits.
From here, we'll form the stems: 12, 13, 14
The leaf values are the last digit. Each separate leaf digit refers to one exact number from the original data set.
Refer to the stem-and-leaf plot below.
As you can see, something like 13.0 is smaller than 13.1; therefore, the whole numbers are smaller than the decimal values for a given stem only.
What is the slope of the line that passes through the points (0,-10) and (-4,-11)? Write your answer in simplest form.
The slope of the line that passes through the points (0,-10) and (-4,-11) will be 1/4.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line. Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other. The more the slope is, the more the line is vertical. When slope is zero, the line is horizontal.
Its slope would be:
[tex]m = \dfrac{y-q}{x-p}[/tex]
Given that the line passes through the points (0,-10) and (-4,-11).
From the formula to find the slope of a line which passes through points
m= y2-y1 / x2-x1
Substitue the points (0,-10) and (-4,-11).
The slope = m = -11-(-10) /. -4-0
m = -1/-4
m = 1/4
Therefore, the slope of the line that passes through the points (0,-10) and (-4,-11) will be 1/4.

consider the distance equation d=rt, where d is the distance (in feet), r is the rate (in feet per second), and t is the time (in seconds). you run fir 50 seconds. Are the distance you run and the rate you run at proportional? Use a graph to justify your answer.
Answer:
yes, they are proportional
Step-by-step explanation:
A proportion is a relation that can be modeled by a straight line through the origin. The equation will have the form ...
y = kx
where x is the independent variable, y is the dependent variable, and k is a constant of proportionality.
__
If you start with the equation relating distance, rate, and time:
d = rt
and you fix the time at 50 seconds, then the equation becomes ...
d = 50t
This is the equation of a proportion with a constant of proportionality of 50. It tells you the distance run is proportional to the rate you run. When this equation is graphed, it is a straight line through the origin.
