The surface formed by the equation 25x²+4y²+z²=100 is an ellipse.

In mathematics, an ellipse is a planar curve with two focus points, where the total of the two distances from any point on the curve to the focal points is a constant. It generalises the shape of a circle, a unique variety of ellipse in which the two focus points coincide. The eccentricity of an ellipse is used to calculate its length.

We may set one of the variables at a constant value and then plot the resulting 2D curve in the plane created by the other two variables in order to sketch the surface. This procedure can be repeated for various constant values to get a rough surface drawing.

What is verbal sentence ?

Verbal sentences consist of a verb + subject + object or adverbial phrase. The subject and object can be either nouns or pronouns.

After solving the equation we get square of n which is equal to three times of eight

If the subject is a pronoun, it is always a suffix; and if the object is pronoun, it is always a dependent pronoun. When the subject is a pronoun, the word order is normal, meaning that the subject follows the verb and precedes the object.

If the subject is a noun and the object is a dependent pronoun, the pronoun object is before the noun subject.

The dative has a special place in the word-order of verbal sentences. It is expressed by the preposition n in addition to a noun or pronoun referring to a person, if the subject is a pronoun. It assumes a third place following the verb and its subject. However, if the subject is a noun, the dative is allocated a forward position and occurs before the subject.

If the subject is a noun and the object is a pronoun and the sentence consists of a dative, the word order is thus:

Verb + dative + dependent pronoun (object) + subject

Answer:

Step-by-step explanation:

Josslyn burns 7 calories per minute while swimming and 5 calories per minute while practicing yoga. Let x be the number of minutes she spends swimming and y be the number of minutes she spends practicing yoga.

The total number of calories burned, C, is given by:

C = 7x + 5y

To burn at least 500 calories each day, we can write the inequality:

7x + 5y ≥ 500

This inequality states that the total number of calories burned from swimming and practicing yoga, 7x + 5y, must be greater than or equal to 500. Josslyn can achieve this goal by spending a combination of x minutes swimming and y minutes practicing yoga.

Answer:

25 horse shoe magnets

Step-by-step explanation:

A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare numbers, and you can compare them using division.

If the ratio is 2: 5 (bar magnet: horse shoe magnet) then we can use this ratio to solve for how many horse shoe magnets there are if there are 10 bar magnets.

To solve for '?', we can use this expression:

We multiply by 5 because in order to go from 2 to 10 (2: 5, 10: ?), we multiply the 2 by 5.

Therefore, for every 10 bar magnets, there are 25 horse shoe magnets.

For the polynomial 9x² - 49, the values of a and b include the following:

a = 3x

b = 7

In Mathematics, the standard form for a difference of two (2) squares is modeled or represented by this mathematical expression:

a² - b² = (a + b)(a - b).

Where:

a and b are numerical values (numbers or numerals).

Based on the information provided, we have the following polynomial function:

9x² - 49

By using the sum-product pattern, we have the following:

9x² + 21x - 21x - 49

By writing the common factor from the two pairs, we have the following:

(9x² + 21x) + (-21x - 49)

3x(3x + 7) - 7(3x + 7)

By rewriting in factored form, we have the following:

9x² - 49 = (3x - 7)(3x + 7)

You have $28.75 left to spend on diapers for Jake.

What is the percentage?

Percentage refers to a way of expressing a number as a fraction of 100. It is often denoted by the symbol "%". For example, if 30 out of 100 students in a class are girls, the percentage of girls in the class is 30%. Percentages are commonly used in many fields, such as finance, statistics, and science, to express proportions, rates, and changes over time.

The total percentage of money spent on the blanket, toys, and clothes is 15% + 25% + 40% = 80%.

Therefore, the amount of money spent on Jake's supplies is $115, which is 80% of the total budget. We can set up the equation:

0.8x = 115

Solving for x, we get:

x = 115 ÷ 0.8 = $143.75

So, the total budget for Jake's supplies is $143.75.

To find out how much money is left for diapers, we need to subtract the amount spent on blanket, toys, and clothes from the total budget:

$143.75 - 15% of $143.75 - 25% of $143.75 - 40% of $143.75

= $143.75 - $21.56 - $35.94 - $57.50

Step-by-step explanation:

I = prt

I = interest earned

p = principal = amount invested

r = interest rate; 5.25% = 5.25/100 = 0.0525

t = time in years; 6 months = 0.5 years

$4,000.00 at 5.25% interest

I = 4000 × 0.0525 × 0.5 = 105

$105 interest in 6 months

A permutation is an orderly arrangement of things or numbers. Combinations are a means to choose items or numbers from a collection or set of items without worrying about the items' chronological order.

Given:

Two events take place.

Let event A be flipping a coin

Let event B be rolling a 6-sided die.

Now, a coin has two faces; one is the head and the other is the tail.

So, the possible outcomes of event A are: {H, T}

H → Head, T → Tail.

Now, a six-sided die has six faces each marked with a number. The numbers marked ranges from 1 to 6.

So, the possible outcomes of event B are {1, 2, 3, 4, 5, 6}

Now, each element of set A should match all the elements of set B.

Now, the tabular form should have a row of outcomes of B and a column of outcomes of event A. Thus,

The probability and the likelihood, that the marble drawn is not red is high which is 4/5.

To determine how likely something is gonna occur, use probability. Several things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is. In the probability scale, 0 indicates an impossibility and 1 indicates a certainty.

It is stated that there is a 2/10 chance of drawing a red marble at random.

We can deduct the likelihood of drawing a red marble from one to determine the likelihood that the drawn marble is not red (since the probability of an event and its complement add up to 1).

So, the probability of drawing a marble that is not red is -

1 - 2/10 = 8/10 = 4/5

Therefore, the probability that the marble drawn is not red is 4/5.

The likelihood of an event is a measure of how plausible it is, given some evidence or knowledge.

In this case, we can say that the likelihood of drawing a marble that is not red is high, since there are more marbles in the jar that are not red than those that are red.

Therefore, the likelihood of drawing a marble that is not red is high.

Identifying the slope and y-intercept is necessary before putting the equation in y-intercept (y=mx+b) form and figuring out the equation of a graphed line. The slope is the y-to-x change ratio.

Plotting points on the coordinate plane with values for b and calculating the appropriate values for c is necessary to graph the equation c = 2b + 6.

Let's pick some b values and determine the matching c values:

c = 2(0) + 6 = 6 when b = 0.

If b = 1, then c = 2(1) + 6 = 8.

The solution to the system 2xy+3=4y 3xy+2=5y is  (x, y) = (22/5, -30/29).

Starting with the first equation:

2xy + 3 = 4y

We can rearrange it to solve for one of the variables in terms of the other:

2xy - 4y = -3

2y(x - 2) = -3

y = -3/(2(x - 2))

Now we can substitute this expression for y into the second equation:

3x(-3/(2(x - 2))) + 2 = 5(-3/(2(x - 2)))

Multiplying both sides by 2(x - 2) to clear the fraction:

-9x + 4(x - 2) = -30

-9x + 4x - 8 = -30

-5x = -22

x = 22/5

Now we can use this value of x to solve for y:

Adding k to both sides gives the "y =" form ...

Anything times 0 is 0. So, the product 0(x +2) is 0.

Anything added to 0 is unchanged. So, the sum y = 0 -3 is y = -3.

When the slope is zero we get y= -3.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
