Given:
Area of Pacific ocean = 161.8 12 x 10⁶ square kilometers
Area of Atlantic ocean = 85133000 square kilometers
Let's find how many times greater is the area of the pacific ocean than the Atlantic ocean.
To find how many times greater, divide the area of the Pacific ocean by the area of the Atlantic ocean.
Thus, we have:
[tex]\begin{gathered} \frac{161.8\times10^6}{85133000} \\ \\ =\frac{161.8\times10^6}{85.133\times10^6} \\ \\ =1.9 \end{gathered}[/tex]Therefore, the area of the Pacific ocean is 1.9 times greater than the area of the Atlantic ocean.

Determine the value of b.
b3 = 125
b = 41.7
b = ±41.7
b = 5
b = ±5
Answer:
b^3 = 5
Step-by-step explanation:
b^3 = 125
cube root of b^3 = cube root of 125
the cube root of 125 is 5
-5 is not an equivalent solution (-5)(-5)(-5) =/ (not equal to) 125
so b=5
remember ± means if -5 and 5 are equal to 125, in this case it is not...so its just 5.
I hope I explained this well!
The value of b for the expression b³ = 125 is 5.
Option C is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
b³ = 125
Cube root on both sides.
b = ∛125
b = 5
We can not use -5 because.
-5 x -5 x -5 = -125
This is not possible
Thus,
The value of b is 5.

Your friend has a fish tank that can hold 15 ft of water. Hewants to get a few more fish and now needs a bigger tank. Ifhe wants a tank that is 1.5 times bigger, how much water canwill it hold?
As given by the question
There are given that the fish tank can hold 15 ft water.
Now,
According to the question, he wants a tank that is 1.5 times bigger.
Then,
Suppose the size of the first tank is x,
That means, in the x size of the tank, there are a total of 15 ft of water
Then,
After some time, he increased the size of the tank 1.5 times bigger
That means, the size of the new tank was 1.5x
Then,
[tex]\begin{gathered} x\rightarrow15ft \\ 1.5\rightarrow15\times1.5 \\ =22.5ft \end{gathered}[/tex]Hence, a total of 22.5 ft of water can will it hold in the new tank.

Which function has the greatest y-intercept?Group of answer choicesf(x)g(x)h(x)All three functions have the same y-intercept.
Three functions are given. It is required to find the greatest y-intercept of the three functions.
To do this, find the y-intercept of each function and check which of them has the greatest value.
The given equation for f(x) is:
[tex]f(x)=-3x-5[/tex]Notice that this is a linear function in the slope-intercept form, y=mx+c.
Where m is the slope and c is the y-intercept.
Compare to the given equation; it follows that the y-intercept of f(x) is c=-5.
The y-intercept of f(x) is -5.
The graph of g(x) is given.
Recall that the y-intercept is the point where the graph of a function intersects the y axis.
Hence, the y-intercept of g(x) is -3.
The equation for h(x) is:
[tex]h(x)=2\cos\left(2x-\pi\right)+4[/tex]To find the y-intercept, substitute x=0 into the equation:
[tex]\begin{gathered} h(0)=2\cos\left(2(0)-\pi\right)+4 \\ \Rightarrow h(0)=2\cos\left(0-\pi\right)+4=2\cos(-\pi\rparen+4 \\ \Rightarrow h(0)=2(-1)+4=-2+4=2 \end{gathered}[/tex]Hence, the y-intercept of h(x) is 2.
It follows that h(x) has the greatest y-intercept.

What is inequalities ?Mathematical expressions with inequalities on both sides are known as inequalities. In an inequality, we compare two values as opposed to equations. In between, the equal sign is changed to a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The Pythagorean theorem ?A hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.

A side of the triangle below has been extended to form an exterior angle of 135°. Find the value of xx.
For the given measures of exterior angle and angles in a triangle , the unknown measure of angle x is equal to 23°.
As given in the question,
In a given triangle,
Measure of exterior angle is equal to 135°
Exterior angle +Adjacent interior angle = 180°
⇒ 135° + Adjacent interior angle = 180°
⇒ Adjacent interior angle = 180° -135°
⇒ Adjacent interior angle = 45°
In a triangle,
Sum of opposite interior angles = Measure of exterior angle
⇒ x° + 112° = 135°
⇒ x° = 135° -112°
⇒ x° = 23°
Therefore, for the given measures of exterior angle and angles in a triangle , the unknown measure of angle x is equal to 23°.

If families consumed apples and granola bars at constant rates, which food had the higher unit rate per hour? Write an equation that represents the rate apples were consumed per minute Write an equation that represents the rate granola bars were consumed per minuteEnter the equation in y=mx format
Answer:
• Apples: y=1/6x
,• Granola bars: y=1/5x
Explanation:
Apples
First, we calculate the unit rate for the consumption of apples.
Using the points (0,0) and (12,2):
[tex]\begin{gathered} \text{Unit Rate=}\frac{2-0}{12-0} \\ =\frac{2}{12} \\ =\frac{1}{6} \end{gathered}[/tex]Therefore, an equation that represents the rate apples were consumed per minute is:
[tex]y=\frac{1}{6}x[/tex]Granola Bars
We calculate the unit rate for the consumption of granola bars.
Using the points (0,0) and (60,12):
[tex]\begin{gathered} \text{Unit Rate=}\frac{12-0}{60-0} \\ =\frac{12}{60} \\ =\frac{1}{5} \end{gathered}[/tex]Therefore, an equation that represents the rate apples were consumed per minute is:
[tex]y=\frac{1}{5}x[/tex]What is the slope of this line?

The slope of the line is -3/4.

We have to find the slope of the line.
The formula for the slope is:
slope(m) = [tex](y_{2} - y_{1} ) /( x_{2} - x_{1})[/tex]
[tex](x_{1} , y_{1} )[/tex] = (0,7)
([tex]x_{2} , y_{2}[/tex]) = (4,4)
Putting the value we have,
m = (4-7)/ ( 4-0)

The constant of proportionality that Busy Bee store bottles of fresh jars of honey is 12 hours.
What is the constant of proportionality?The rate at which the fresh jars of honey is stored increases with time. This means that there is a direct proportional relationship between the jars of honey stored and time.
When there is a direct proportion, the two variables move in the same direction. As time increases, the jars of honey stored increases.
The equation that is used to represent direct proportion is:
y = bx
