Answer:
C(r) is the area of the base of a cylindrical tank with radius r.
We know that this area is:
C(r) = pi*r^2
S(x) is the area of the square base where x is the side length of the base.
S(x) = x*x
Now, we have the expression:
S( C(r)) wich means that we are evaluating the function S(x) in the point x = C(r)
Now, we have a problem here.
In S(x), S(x) is in units of area, and x is in units of length.
And the same for C(r), C(r) is in units of area, and r in units of length.
then we can not have x = C(r)
Then this expression does not represent anything, because the units do not match, so it has no physical sense.

The value of the function k(h(10)) will be 11. The correct option is A.
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given h(t) = t²+t+ 12 and k(t) = √t-1, we are to find k(k.h)(10)
k{h(t)} = k{ t²+t+ 12}
Since k(t)= √t-1, we will replace the variable t in the function with t²+t+ 12
k(h(t)) = √{(t²+t+ 12)-1}
k(h(t)) = √t²+t+12-1
k(h(t)) = √t²+t+11
Substituting t = 10 into the resulting function;
k(h(10)) = √(10)²+(10)+11
k(h(10)) = √100+10+11
k(h(10)) = √121
k(h(10))= 11
Therefore, the value of the function k(h(10)) will be 11. The correct option is A.

What is the difference between the high and low temp in the thermometer?
Answer:
The difference between the high and low temperature in the thermometer is 23°F.
Step-by-step explanation:
Given information: Highest temperature = 20°F and the lowest temperature = -3°F.
We need to find the difference between the high and low temperature in the thermometer.
Difference between the high and low temperature is
Difference = Highest temperature - Lowest temperature
Difference = 20°F - (-3°F)
Difference = 20°F + 3°F
Difference = 23°F
Therefore the difference between the high and low temperature in the thermometer is 23°F.

PLEASE HELP I HAVE 20 POINTS The mass of the Eiffel Tower is about 9.16 ⋅ 10^6 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 10^8 kilograms. Approximately how many more kilograms is the mass of the Golden Gate Bridge than the mass of the Eiffel Tower? Show your work and write your answer in scientific notation. (10 points)
Step-by-step explanation:
8.05 * 10^8 - 9.16 * 10^6
= 10^6 * (8.05 * 10^2 - 9.16)
= 10^6 * (805 - 9.16)
= 10^6 * (795.84)
= 10^8 * 7.9584
Therefore the answer in scientific notation is 7.9584 * 10^8.

Step-by-step explanation:
To solve for this use the mnemonic device PEMDAS (parenthesis, exponent, multiplication, division, addition, subtraction)
First multiply -4 and 2 (-8)
(-8)^2/2-9-5
Next find out what -8 squared is (64)
64/2-9-5
Now simplify the denominator
64/-12
Lastly, divide 64 and -12

A total of 360 people were surveyed. Of the people surveyed, 70 said they were an early bird and preferred tea. The percentage of people surveyed who are night owls is ___%. The percentage of early birds who prefer to drink tea is ___%.
Answer:
A total of
360
people were surveyed. Of the people surveyed,
70
said they were an early bird and preferred tea. The percentage of people surveyed who are night owls is
60
%. The percentage of early birds who prefer to drink tea is
49
%.
Step-by-step explanation:
The last row and the last column give the total number of people surveyed, which is 360.
The joint frequency of the Early Bird column and the Tea row show that 70 people said they were an early bird and preferred tea.
To get the percentage of night owls, divide the total number of night owls by the total number of people surveyed and multiply by 100:
To get the percentage of early bird tea drinkers, divide the joint frequency of early birds and tea by the marginal total number of early birds and multiply by 100:
From total of 360 people surveyed, 70 people are early birds and preferred tea. Hence night owls is 60% and people who prefer to drink tea is 49%
What is a survey?A survey is a method of data collection and can be in the form of questionnaires and interviews. The survey tells us about the demands and needs of the people.
As per the question, the last row and column give us a total of 360. Those who are early birds and take tea are 70% of the population. To get the percentage we need to X night owls by the number of people surveyed multiplied by 100.
For the early bird tea, the total frequency of early birds by the marginal total number of early birds multiplied by 100.

1. Select all drawings in which a corresponding height h for a given base b is correctly identified
Answer:
A, B, D, F
Step-by-step explanation:
To determine which of the drawings are well labelled according to their corresponding height (h) for a given base, recall the following:
1. Base of a triangle could be any of the 3 sides of a triangke.
2. Height of a triangle is the perpendicular distance from the corner opposite the base to the base.
3. The height of a triangle could be indicated from outside the triangle.
Going by this 3 criteria, therefore, the following drawings can be said to be well labelled and correctly identifies by their corresponding height with respect to their bases:
A, B, D, F

The property of equality is demonstrated moving from step a to step b is linear.
What is a linear equation?The linear equation is defined as the equation having a degree of one or the power of the variable will be one. The linear equation is represented by y = mx + c. Here y is the variable, m is the slope and, c is the intercept.
Given that b = 3, and m = 5, and y = mx + b then, b. y = 5x + 3. The equation can be formed as below:-
y = mx + c
y = 5x + 3
Therefore, the property of equality is demonstrated moving from step a to step b is linear.

11. Higher Order Thinking Using what you know
about angle pairs formed by parallel lines and a
transversal, how are 21, 22, 23, and 24 related
in the trapezoid? Explain.
3
Answer:
m∠1 + m∠3 = m∠2 + m∠4
Step-by-step explanation:
In the figure attached,
In the given trapezoid if two sides AB and CD are parallel and AD is a transverse,
m∠1 + m∠3 = 180°
Similarly, if AB and CD are parallel and BC is a transverse,
m∠2 + m∠4 = 180°
Therefore, m∠1 + m∠3 = m∠2 + m∠4 is the relation between these angles.

A sequence of numbers consists of natural numbers that are
not perfect squares. What is the 1000th member of this
sequence?
Given :
A sequence of numbers consists of natural numbers that are
not perfect squares.
To Find :
The 1000th member of this sequence .
Solution :
Now , [tex]31^2=961[/tex] and [tex]32^2=1024[/tex] .
So , there are 31 numbers before 1000 which are perfect square .
Therefore , the [tex]999^{th}[/tex] is 1000+31 = 1031 .
Also , the first perfect square after 1000 is 32 .
So , we have to continue to 1031 + 1 = 1032 to compensate for the 32nd square.
Therefore , the 1000th member of this sequence is 1032 .
Hence , this is the required solution .

what is the solution of the system of linear equations? y = 3x - 2 y - 2 = x
Answer:
x = 2 y = 4
Step-by-step explanation:
y = 3x - 2
x = y - 2
Plug in the equation of x into the first equation and solve for y.
y = 3x - 2
y = 3(y - 2) - 2 Multiply out
y = 3y - 6 - 2
y = 3y - 8 Add 8 to each side
y + 8 = 3y - 8 + 8 8 cancels on the right
y + 8 = 3y Subtract y from each side
y - y + 8 = 3y - y The y on the left cancels
8 = 2y Divide each side by 2
8/2 = 2y/2 2 on the right cancels because 2/2 = 1
8/2 = y
4 = y
Now plug your answer into the 2nd equation given to solve for x.
x = y - 2
x = 4 - 2
x = 2
x = -3y + 1
-3x - 3y = -15
Answer:
X = 3 x − 14
y = − x + 5
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
