What is the area model of 37 times 9
Answer:
333
Step-by-step explanation:
A student decides it is possible to estimate the capacity of a test tube by treating it as a
rectangle and neglecting it's "roundness". On this basis, the student finds the capacity of the
test tube to be 100.5 ml. In fact, the real capacity of the test tube is 100.0 ml. What percent
error has resulted from the student's assumption?
The percent error that has resulted from the student's assumption is 0.5%.
The percent error is used to calculate the percentage error between an experimental measured value and a theoretical actual value.
Percentage error formula = |E-T|/|T| x 100
where E is the experimental value and T is the theoretical value.
Given, the experimental measured value (E) = 100.5 ml and theoretical actual value (T) = 100.0 ml
By using the Percentage error formula, simply put the value of the capacity of the test tube which was found by the student as an experimental measured value and real capacity of the test tube as a theoretical actual value, we get
=|(100.5−100.0)||100.0| × 100
=0.5/100×100
=0.005×100
=0.5%
=0.5% error
∴ 0.5% error has resulted from the student's assumption.

Write each equation in logarithmic form.
8²=64
We get the equation in logarithmic form as log₈ 64 = 2
A “logarithmic equation” is an equation which involves the “logarithm” of any expression which is containing a variable.
Now, we have been given an equation:
8² = 64
We need to write it in the logarithm form.
We know that, it will be written as:
log₈ 64 = 2
Since the power goes after the equal sign, so 2 is placed after the equal sign.
The actual value is taken after log, so 64 is placed there and the base number is taken as the base for the log, so 8 is taken as the base for the log.
Therefore, we get the equation in logarithmic form as log₈ 64 = 2

Write 5=log₂x₊₁(a+b) in exponential form.
The exponential form of the function 5 = log₂ₓ₊₁(a₊b) is (2x ₊ 1)⁵ = (a₊b).
Given the function is:5 = log₂ₓ₊₁ (a₊b)
we are asked to determine the exponential form of the above function.
The exponential form is an easier way to represent repeated multiplication involving exponents and bases.
It is easy to quickly convert an exponentially written expression into a logarithm using the following formula.
here we have the form loge b =a5 = log₂ₓ₊₁(a₊b)
then, e = 2 , a = 5 and
b = (a₊b)5 = log₂ₓ₊₁(a₊b)
therefore, exponential form is:
(2x ₊ 1)⁵ = (a₊b).
hence we get the required exponential form as (2x ₊ 1)⁵ = (a₊b).

Solve a System of Linear Equations by Graphing
In this chapter we will use three methods to solve a system of linear equations. The first method we’ll use is graphing. The graph of a linear equation is a line. Each point on the line is a solution to the equation. For a system of two equations, we will graph two lines. Then we can see all the points that are solutions to each equation. And, by finding what the lines have in common, we’ll find the solution to the system.
Most linear equations in one variable have one solution, but we saw that some equations, called contradictions, have no solutions and for other equations, called identities, all numbers are solutions. Similarly, when we solve a system of two linear equations represented by a graph of two lines in the same plane, there are three possible cases, as shown in Figure 5.1.1 :
This figure shows three x y-coordinate planes. The first plane shows two lines which intersect at one point. Under the graph it says, “The lines intersect. Intersecting lines have one point in common. There is one solution to this system.” The second x y-coordinate plane shows two parallel lines. Under the graph it says, “The lines are parallel. Parallel lines have no points in common. There is no solution to this system.” The third x y-coordinate plane shows one line. Under the graph it says, “Both equations give the same line. Because we have just one line, there are infinitely many solutions.”
Figure 5.1.1
For the first example of solving a system of linear equations in this section and in the next two sections, we will solve the same system of two linear equations. But we’ll use a different method in each section. After seeing the third method, you’ll decide which method was the most convenient way to solve this system.

TO SOLVE A SYSTEM OF LINEAR EQUATIONS BY GRAPHING.
Graph the first equation.
Graph the second equation on the same rectangular coordinate system.
Determine whether the lines intersect, are parallel, or are the same line.
Identify the solution to the system.
If the lines intersect, identify the point of intersection. Check to make sure it is a solution to both equations. This is the solution to the system.
If the lines are parallel, the system has no solution.

if f(1)=8and f(N)=f(n+1)+4 then find the value of f(6)
The function definition is an arithmetic sequence and the value of the function f(6) is -12
How to determine the value of the function f(6)?The function definition is given as
f(1) = 8
f(n) = f(n + 1) + 4
Rewrite the above function as
f(n + 1) = f(n) - 4
Set n = 1
So, we have
f(1 + 1) = f(1) - 4
This gives
f(2) = f(1) - 4
So, we have
f(2) = 8 - 4
Evaluate
f(2) = 4
Set n = 2
So, we have
f(2 + 1) = f(2) - 4
This gives
f(3) = f(2) - 4
So, we have
f(3) = 4 - 4
Evaluate
f(3) = 0
Set n = 3
So, we have
f(3 + 1) = f(3) - 4
This gives
f(4) = f(3) - 4
So, we have
f(4) = 0 - 4
Evaluate
f(4) = -4
Set n = 4
So, we have
f(4 + 1) = f(4) - 4
This gives
f(5) = f(4) - 4
So, we have
f(5) = -4 - 4
Evaluate
f(5) = -8
Set n = 5
So, we have
f(5 + 1) = f(5) - 4
This gives
f(6) = f(5) - 4
So, we have
f(6) = -8 - 4
Evaluate
f(6) = -12
Hence, the value of the function f(6) is -12

How do you answer 532÷4 using long division?
If we divide five hundred and thirty two by four using long division method, we obtain one hundred and thirty three.
What is long division?The term long division implies dividing repeatedly until we are able to arrive at the final result. In this case, we are asked to carry out the division of 532÷4 using long division.
First we have to divide the digits one after the other. This process is a bit iterative and takes a little time for us to do in the process of the long division.
Now; when we divide five by 4 we obtain one remainder one we then add the one that remains to thirty two and we have one hundred and thirty two.
Then we divide one hundred and thirty two by four, we can see that there are thirty three fours in one hundred and thirty two. The final result of our long division now becomes one hundred and thirty three.
Thus, if we divide five hundred and thirty two by four using long division method, we obtain one hundred and thirty three.

Angle A and angle B are supplementary and ∠A ≅ ∠C. If m∠A = (16x − 7)° and m∠B = (21x + 2)°, what is m∠C in degrees?
m∠C =?
Two angles have sum as 180° called supplementary angle so the measure of angle C m∠C will be 68.68°.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
Given that,
Angle A and angle B are supplementary
Since the supplementary angle has a sum of 180 degrees.
So,
m∠A + m∠B = 180°
16x - 7 + 21x + 2 = 180
16x + 21x + 7 - 2 = 180
37x + 5 = 180
37x = 175
x = 4.78
So,
m∠A = 16(4.78) - 7 = 68.68°
Since m∠C = m∠A
So,
m∠C = 68.68°
Hence"The measure of angle C m∠C will be 68.68° ".
