According to the National Oceanic and Atmospheric Administration, the blue whale is the largest animal on Earth. Blue whales weigh approximately 3×105 pounds. Narwhals, which are also a type of whale, weigh approximately 2×103 pounds. How many times heavier is the blue whale's weight than the narwhal's weight?
Answer: The blue whale's weight is 150 times heavier than the narwhal's weight.
Step-by-step explanation:
Given: Weight of Blue whale = [tex]3\times10^5\text{ pounds}[/tex]
Weight of Narwhal = [tex]2\times10^3\text{ pounds}[/tex]
Number of times blue whale's weight is heavier than the narwhal's weight = [tex]=\dfrac{\text{Weight of Blue whale}}{\text{Weight of Narwhal }}[/tex]
[tex]=\dfrac{3\times10^5}{2\times10^3}\\\\=1.5\times10^{5-3}\ \ \ [\dfrac{a^m}{a^n}=a^{m-n}]\\\\=1.5\times10^2\\\\=1.5\times100=150[/tex]
Hence, the blue whale's weight is 150 times heavier than the narwhal's weight.

A culture of bacteria triples by the end of each hour. If there were initially 40 bacteria in a culture, how many bacteria should there be after 3 hours?
Answer:
There would be 1080 bacteria in the culture.
Step-by-step explanation:
Initial number of bacteria = 40
Given that
culture of bacteria triples by the end of each hour
Number of bacteria after 1 hour = 40*3 (multiplying initial number of bacteria by 3)
Number of bacteria after 1 hour = 120
number of bacteria after 2 hours = 3*Number of bacteria after 1 hour = 3*120
number of bacteria after 2 hours =360
number of bacteria after 3 hours = 3*Number of bacteria after 2 hour = 3*360 = 1080
Thus,
there would be 1080 bacteria in the culture.
Answer:
1080 bacteria

for the first one it is the second option because of one property of logarithms:
log(a)-log(b)=log[tex]\frac{a}{b}[/tex]
for the second one using the same property we can say that we third option is correct and not the second one but we use one more property of the logarithm
loga(b)^x=xloga(b) the power of the logarithm becomes a fator and [tex]\sqrt[3]{x}[/tex] is equal to [tex]x^{\frac{1}{3}}[/tex]

Enter the range of values for x
3 < x < ?
Answer:
3 < x < 7
Step-by-step explanation:
From the diagram; |AB| = |AC|
The length AB is calculated as;
[tex]Sin\ 52^o = \frac{|BD|}{|AB|} \\\\|AB| = \frac{|BD|}{Sin\ 52^o} \\\\|AB| = \frac{12}{Sin\ 52^o} \\\\|AB| =15.228 \ m[/tex]
The length CD is calculated as;
[tex]Sin \ 31^o = \frac{|CD|}{|AC|} \\\\|CD| = |AC| \ \times \ Sin \ 31^o \\\\|CD| = 15.228 \ \times \ 0.515\\\\|CD| = 7.84[/tex]
|CD| = 2x - 6
2x - 6 = 7.84
2x = 7.84 + 6
2x = 13.84
x = 13.84 / 2
x = 6.92
x ≅ 7
Thus, 3 < x < 7

Find the diameter of a circle if its area is
a. 100cm2
Ibucm2
c. 400mcm2
d. - ncm2
4
Answer:
[tex]Diameter = 11.28[/tex]cm --- (a)
[tex]Diameter =22.58[/tex] cm --- (c)
Step-by-step explanation:
Only (a) & (c) are clear enough to be solved. Others are not properly presented.
Use the following explanations of (a) & (c) to answer others.
[tex]a.\ Area = 100cm^2[/tex]
Area is calculated as:
[tex]Area = \pi r^2[/tex]
Substitute 100 for Area
[tex]100 = \pi r^2[/tex]
Take π as 3.14. So, the expression become
[tex]100 = 3.14 r^2[/tex]
Divide both sides by 3.14
[tex]\frac{100}{3.14} = \frac{3.14 r^2}{3.14}[/tex]
[tex]\frac{100}{3.14} = r^2[/tex]
[tex]r^2 = \frac{100}{3.14}[/tex]
[tex]r^2 = 31.847133758[/tex]
Solve for r
[tex]r = \sqrt{31.847133758[/tex]
[tex]r = 5.64[/tex]
But diameter = 2 * radius
So:
[tex]Diameter = 2 * 5.64[/tex]
[tex]Diameter = 11.28[/tex]
[tex]a.\ Area = 400cm^2[/tex]
Area is calculated as:
[tex]Area = \pi r^2[/tex]
Substitute 400 for Area
[tex]400 = \pi r^2[/tex]
[tex]400 = 3.14 r^2[/tex]
Divide both sides by 3.14
[tex]\frac{400}{3.14} = \frac{3.14 r^2}{3.14}[/tex]
[tex]\frac{400}{3.14} = r^2[/tex]
[tex]r^2 = \frac{100}{3.14}[/tex]
[tex]r^2 = 127.388535032[/tex]
Solve for r
[tex]r = \sqrt{127.388535032[/tex]
[tex]r = 11.29[/tex]
But diameter = 2 * radius
So:
[tex]Diameter = 2 * 11.29[/tex]
[tex]Diameter =22,58[/tex]

Four banks have provided proposals for a savings account. Which scenario provides exponential growth that will best benefit the account holder?
A.The deposit increases by 3%, percent of its current value, compounded annually.
B.The deposit increases by 3%, percent of its current value, compounded monthly.
C. The deposit increases by 5%, percent of its initial value each year.
D. The deposit increases by 0.40% point, percent of its initial value each month.
Answer:
B. The deposit increases by 3% of its current value, compounded monthly.
Step-by-step explanation:
When compounded monthly that means the account is getting more money monthly rather than annually, or each year, so this answer choice would give the best benefit to the account holder. I did this problem on Khan Academy myself and this was the correct answer.

2. The perimeter of rectangle is 48cm. If the
files are in the ratio 3 : 5, find the length
of the sides
lets the length be 3x
width be 5x
perimeter = 48
so
3x +5x=48
8x = 48
x =48/8
x= 6
so.
3x = 3×6 = 18
5x = 5×6= 30

The tree would be 27.6
Step by Step:

the equation of the line a is given as y = -3/4 x -2. Suppose the line a is parallel to line b and lime t is perpendicular to line a. Point (0, 5) lines on both line b and line t.
Answer: The equation for line b is [tex]y = -\frac{3}{4}x + 5[/tex]
The equation for line t is [tex]y= \frac{4}{3} x+5[/tex]
The attachment shows the original line in green, the parallel line b in red, and the perpendicular line t in blue.
Step-by-step explanation: Use slope intercept form, y = mx + b
The given coordinate, (0,5) is on the y-axis, so 5 will be the y-intercept of the equation. Keep the slope of the original equation and substitute the new value for "b"
To write the equation for line t
Both lines share the y-intercept, (0,5) so the "b" term will be the same. The slope of a perpendicular line is the reciprocal of the original slope with the opposite sign.
So invert 3/4 to become 4/3 and change the negative sign to positive.
The resulting equation is y = 4x/3 + 5
