Using the metric system, a Deka is 10 of a unit. In the metric system, the prefix "deka" (also written as "deca") represents 10 of a unit. So, the correct option is C.

The metric system is an internationally recognized system of measurement that is used in many countries around the world. It is also known as the International System of Units (SI), and it is based on a decimal system, meaning that units are related to each other by powers of 10.

The metric system has a set of base units that are used to measure different types of quantities. The base units are:

Meter (m): used to measure length or distance

Kilogram (kg): used to measure mass or weight

Second (s): used to measure time

Each base unit has a set of prefixes that can be used to create larger or smaller units. These prefixes are based on powers of 10, and they are added to the base unit to indicate the size of the unit. Here are the most common prefixes and their meanings:

Kilo- (k): 1000 times the base unit (e.g., 1 kilogram = 1000 grams)

Hecto- (h): 100 times the base unit (e.g., 1 hectometer = 100 meters)

Deka- (da): 10 times the base unit (e.g., 1 dekagram = 10 grams)

Using these prefixes, you can create units that are appropriate for the quantity you are measuring.

Step-by-step explanation:

The equation of the ellipsoid is[tex]\frac{x^{2} }{a^{2} } + \frac{y^{2} }{b^{2} } +\frac{z^{2} }{c^{2} } =1[/tex]

The equation of an ellipsoid is represented as:

[tex]\frac{x^{2} }{a^{2} } +\frac{y^{2} }{b^{2} } +\frac{z^{2} }{c^{2} } =1[/tex]

Given that the ellipsoid passes through the points (±6,0,0),(0,±7,0) and (0,0,±5)

It means that:

(±a,0,0)  = (±6,0,0)

(0,±b,0) = (0,±7,0)

(0,0,±c) = (0,0,±5)

By comparison, we have:

±a=±5

±b=±6

±c=±7

So, the equation of the ellipsoid becomes:

[tex]\frac{x^{2} }{a^{2} } +\frac{y^{2} }{b^{2} } +\frac{z^{2} }{c^{2} } =1[/tex]

By substituting the values, the equation of the ellipsoid becomes is

[tex]\frac{x^{2} }{36}+\frac{y^{2} }{49} +\frac{z^{2} }{25} =1[/tex]

.An ellipse is the set of all points on a plane whose distance from two fixed points F and G add up to a constant. In an ellipse, there are two radius measures, one horizontally along the x-axis, the other vertically along the y-axis.For  a circle both these have the same value.

Answer: Let's call the number of bananas your character slipped on as "x". Then, the total points from slipping on bananas would be -3x. And since the total points from slipping on bananas during one race were at most -27, we can write an inequality to represent this:

-3x ≤ -27

Now we'll solve for x:

Divide both sides by -3:

x ≥ 9

So, the least number of bananas your character slipped on is 9.

To find the least number of seconds of race time, we need to multiply the number of bananas by 2 seconds per banana:

9 bananas * 2 seconds/banana = 18 seconds

So, the least amount of race time your character took to slip on bananas is 18 seconds.

Based on the provided information, a. Ramon reads faster and b.it will take Ramon approximately 16.77 hours to read the entire novel if he continues to read at his current rate.

To answer this question, we need to calculate the reading rate of both Skyler and Ramon, and then compare them to see who reads faster. We also need to use Ramon's reading rate to calculate how long it will take him to read the entire novel.

a. To calculate Skyler's reading rate, we can divide the number of pages she has read by the number of hours she has spent reading:

Skyler's reading rate = 145 pages / 5 hours = 29 pages/hour

Similarly, we can calculate Ramon's reading rate:

Ramon's reading rate = 124 pages / 4 hours = 31 pages/hour

Since Ramon's reading rate is higher than Skyler's, Ramon reads faster.

b. To calculate how long it will take Ramon to read the entire novel, we can use his reading rate and the total number of pages in the novel:

Time = Total number of pages / Reading rate

Time = 520 pages / 31 pages/hour = 16.77 hours

So, it will take Ramon approximately 16.77 hours to read the entire novel if he continues to read at his current rate.

In conclusion, Ramon reads faster than Skyler, and it will take him approximately 16.77 hours to read the entire Vigo the Vampire Hunter novel at his current reading rate.

Note: The question is incomplete. The complete question probably is: The new Vigo the Vampire Hunter novel is 520 pages. Skyler has read 145 pages in 5 hours. Ramon has read 124 pages in 4 hours. a.

-10x + 15y = 25

6y = 71

y = 71/6

Now put 71/6 back in for y and solve for x

10x -9(71/6) = 46

10x -106.5 = 46

10x = 152.5

x = 15.25

The required slope of the linear function is $30, and the y-intercept is $75.

When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilize the slope intercept formula, y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula.

To find the slope of the linear function, we need to calculate the change in cost divided by the change in time.

Change in cost = $285 - $105 = $180

Change in time = 7 - 1 = 6

Slope = Change in cost / Change in time = $180 / 6 = $30

To find the y-intercept, we can use the point-slope form of a linear equation, y = mx + b, where y is the cost, x is the time, m is the slope, and b is the y-intercept.

Using the point (1, $105), we can substitute x = 1 and y = $105 into the equation and solve for b:

$105 = $30(1) + b

b = $105 - $30 = $75

Therefore, the slope of the linear function is $30, and the y-intercept is $75.

The linear function can be written as: y = $30x + $75, where x is the number of months of membership and y is the cost of the membership.
