, and comparing them to see that their HCF is
6
. Or, it can be done by dividing both numbers,

42
, simplifying the fraction
=
12
7
, then dividing the starting number with the new simplifiied number, remembering always to divide numerator with numerator and denominator with denominator.
72
12
=
6
or
42
7
=
6
This process works with any two numbers which you want to find the HCF of, and can be simplified into this rule:
If
a
=
any number,
b
=
any number and
c
d
is the simplified fraction of
a
b
,
The HCF
=
a
c
or
=

The diameter of the circle below measures 7 cm,
What is the approximate area of the circle?
A. 14 cm2
B. 22 cm2
C. 38 cm2
D. 154 cm2
Answer: D
Step-by-step explanation:
Remember the formula -
[tex]A = \pi[/tex] × [tex]r^{2}[/tex]
π = 3.14
[tex]r^{2}[/tex] = 7
7² = 49
3.14 x 49 = 153.94
A = π · r² = π · 72 ≈ 153.93804
153.93804 ⇒ 154 (rounded)

Write an equation for the parabola that passes through (1,12) and has vertex (10,-4)
Answer:
y + 4 = (16/81)(x - 10)
Step-by-step explanation:
The general formula for a parabola passing through (x, y) and with vertex (h, k) is y - k = a(x - h)^2.
Here we are told that x = 1, y = 12, h = 10 and k = -4, which gives us:
12 + 4 = a(1 - 10)^2, or
16 = 81a
Then a = 16/81, and the desired parabola is
y + 4 = (16/81)(x - 10)

Answer:
[tex]3^{-3}\cdot \:\:8^{-3}=\frac{1}{24^3}[/tex]
Thus, the equivalent expression is: [tex]\frac{1}{24^3}[/tex]
Step-by-step explanation:
Given the expression
[tex]3^{-3}\cdot 8^{-3}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=8^{-3}\cdot \frac{1}{3^3}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=\frac{1}{3^3}\cdot \frac{1}{8^3}[/tex]
[tex]\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}[/tex]
[tex]=\frac{1\cdot \:1}{3^3\cdot \:8^3}[/tex]
[tex]=\frac{1}{24^3}[/tex]
Thus,
[tex]3^{-3}\cdot \:\:8^{-3}=\frac{1}{24^3}[/tex]
Thus, the equivalent expression is: [tex]\frac{1}{24^3}[/tex]

What is the correct equation to solve for x? Help
Answer:
tan (46°) = 17/x
Step-by-step explanation:
tan (46°) = 17/x
Answer:
tan(46) = 17/x
Step-by-step explanation:
The tangent of an angle is opposite over adjacent, so the tangent of 46 is 17/x, not x/17. Also, sin(46) = opposite/hypotenuse and cos(46) = adjacent/hypotenuse, but we aren’t given the hypotenuse. Therefore, the answer has to be tan(46) = 17/x.

Answer:
Cancerous growth
Step-by-step explanation:
For example, a tumor would be found in MRIs and will have a significant impact on the results and interpretation of a functional MRI. A tumor that is cancerously growing is very crucial to the function of an MRI

The functional MRI also known as fMRI monitors brain anatomy activity
The factor that is least likely to affect the results and interpretation of a
functional MRI is; C. A sinus infection.
Reasons:
MRI stands for magnetic resonance imaging, and it is used to generate
images of the interior of items, such as the human body, without opening
the body, by producing strong magnetic fields, from the built in powerful
magnets.
The parts of the body that are examined by an MRI scan includes, the
internal organs, blood vessels, brain, and spinal cord.
The MRI scan works by tracking radio signals sent by protons in the body
which vary based on the type of tissue.
Due to the requirement for the patient to remain stationary during the
scan, medication may be given. It is also important to not take caffeinated
drinks prior to the examination.
A functional MRI is used to monitor the functioning of the brain's anatomy,
by blood flow change detection.
Therefore, the factor that is least likely to affect the result and
interpretation of a functional MRI is a sinus infection which is the
inflammation of the sinus lining and mucus presence, that rarely cause
neurologic complications.

Lots a Loot Bank charges a monthly service fee and a fee per check, and the chart below shows your total monthly fees in relation to the number of checks issued per month.
Answer:
Monthly service fee is like the fixed cost which is basically the y-value where graph crosses the y-axis.
From graph we see that graph crosses at 1 on y-axis so monthly service fee according to sample graph = $1
Now the per check fee works like slope of the line.
To find the slope we need two points so find any two points on the graph of line. I'm using points (1,0) and (4,3)
now slope can be found using formula
Hence per check fee will be $0.5 as per attached sample graph.
You can use same technique for the original graph given with this question.

A monthly service fee of 0.50 and a per-check fee of 0.50

How far above ground is the flag pole in inches? Round to nearest inch if needed
Answer:
Step-by-step explanation:
You'll use similar triangles to solve this. Set up 2 ratios as a proportion. First, however, you have to convert the 15 inches to feet. If everything else is in feet, then EVERYTHING has to be in feet. 15 inches is equal to 1.25 feet. Now for the equation:
[tex]\frac{3}{x} =\frac{1.25}{6}[/tex]
The first fraction is made up of the heights, 3 being the height of the plumb bob and x being our unknown height of the flagpole; the second fraction is made up of the distances on the ground. Cross multiply to solve:
1.25x = 18 so
x = 14.4 feet, or 14 feet, 4.8 inches

When a regression line was used to model exponential data, the -value was
0.668. If the data are linearized using logarithms and then modeled again
with a regression line, the value will be greater than 0.668.
OA. True
OB. False
The statement about the correlation coefficient of the exponential and logarithmic model is true
How to determine the true value of the statement?The correlation coefficient, r² is given as:
r² = 0.668
An exponential model and a logarithm model are inverse functions.
This means that, their correlation coefficients are also inverse
Given that the correlation coefficient, r² of the exponential data is 0.668.
And the highest value of the correlation coefficient is 1.
This means that the correlation coefficient, r² of the logarithmic data would be less than 0.668
Hence, the given statement is true.
