Daryl's weekly allowance, given the amount he ended with and the amount spent on clothes, is  $ 30

To find the weekly allowance, first find the amount that Daryl had after he had spend half his allowance on clothes. This amount can be found by the formula:

= Amount Daryl ended with - Amount gotten from cleaning oven

= 25 - 10

= $ 15

The amount of $ 15 is the amount out of Daryl's weekly allowance that he had after he had spent on clothes. The $15 is therefore half of the weekly allowance which means that the weekly allowance is:

There are three main steps for solving an absolute value equation isolate the absolute value expression, split the equation into two cases and solve the case.

Isolate the absolute value expression: Start by isolating the absolute value expression on one side of the equation. This can be done by adding or subtracting a constant from both sides of the equation, or by dividing or multiplying both sides of the equation by a constant.

Split the equation into two cases: Once the absolute value expression is isolated, you need to split the equation into two cases: one for when the absolute value is equal to the positive value of the expression inside it, and one for when it is equal to the negative value.

Solve each case: For each case, you will have an equation. Solve it like any other equation and find the solutions.

A chord is a combination of three or more tones (notes) played together.

To determine the notes in a chord, we need to calculate the intervals between the notes. An interval is the distance between two notes. Intervals are measured in half steps (or semitones). A half step corresponds to the interval between two adjacent keys of a piano.

In a major chord, the formula for determining the intervals is 1-3-5. This means the root note (1st note) is a major third (4 half steps) away from the 3rd note and a perfect fifth (7 half steps) away from the 5th note.

For example, if the root note is C, the 3rd note is E and the 5th note is G. The intervals in this chord are C to E (4 half steps) and C to G (7 half steps). Therefore, the chord is a C major chord.

In a minor chord, the formula for determining the intervals is 1-b3-5. This means the root note is a minor third (3 half steps) away from the 3rd note and a perfect fifth (7 half steps) away from the 5th note.

For example, if the root note is F, the 3rd note is Ab and the 5th note is C. The intervals in this chord are F to Ab (3 half steps) and F to C (7 half steps). Therefore, the chord is a F minor chord.

The total number of children Mr. and Mrs. Jones are having is 13 children.

A set comprises elements or members that can be mathematical objects of any sort, including numbers, symbols, points in space, lines, other geometric forms, variables, or even other sets. A set is the mathematical model for a collection of various things.

In set theory, the set containing every element in a collection is the union of all its sets. It is one of the fundamental operations that allows sets to be joined together and connected to one another. A union of zero sets is referred to as a nullary union, because it is by definition equivalent to the empty set.

The symbol "∩" can be used to represent the intersection of sets. According to the definition given above, the intersection of two sets A and B is the collection of all the items that are shared by both sets.

8 refused to go to the family cottage = set A

7 refused a resort spot on the ocean. = Set B

9 refused a camping trip. = Set C

3 will go neither to the family cottage nor the resort = A∩B

4 will go neither to the resort nor on a camping trip = B∩C

6 will go neither to the family cottage nor on a camping trip = A∩C

2 will not go to the family cottage, the resort spot on the ocean or the camping trip = A∩B∩C

Step-by-step explanation:

The answer is [−3,3]. The average rate of change of f(x)=x^2+10 over an interval [a,b] is given by (f(b)-f(a))/(b-a). Since f(x)=x^2+10 is a polynomial of degree two, it is always increasing, and so its average rate of change is always positive. Thus, the average rate of change of f(x) over any interval [a,b] where a<b is positive, so the answer is [−3,3].

On a graph, the absolute value of a number is always non-negative.

The absolute value of a number is defined as the distance of that number from zero on the number line. Since the distance can never be negative, the absolute value of a number is always non-negative.

This is reflected in the graph of an absolute value function. The graph of an absolute value function, |x| is a V-shape that opens upward, with the vertex of the V being the point where the absolute value function equals zero. The two arms of the V extend out from this point, going in opposite directions along the number line. The coordinates of the vertex (0,0) and the graph is always non-negative.

It's important to note that although the absolute value is always non-negative on a graph, the input value (x) can be both positive and negative. The output of the absolute value function (|x|) will always be positive.

Answer:

Bonjour, qui pourrait me donner la réponse de cette exercice s’il vous plaît c’est pour mon DM de maths.

Step-by-step explanation:

=========================================================

Explanation:

Break the 3D figure into two pieces:

The relevant formulas we need are:

where r and h are the radius and height respectively.

The cylinder has radius r = 5 and height h = 17.8

V = pi*r^2*h

V = pi*5^2*17.8

V = 445pi

The cone has the same radius, but the height is h = 24-17.8 = 6.2

V = (1/3)*pi*r^2*h

V = (1/3)*pi*5^2*6.2

V = (155/3)pi

The total volume is then,

445pi+(155/3)pi

(1335/3)pi + (155/3)pi

(1335/3 + 155/3)pi

(1490/3)pi

That's the exact volume of this pencil-shaped figure. This exact volume is in terms of pi.

----------

Now to compute the approximate volume.

If you were to use pi = 3.14, then the approximate volume is

(1490/3)pi = (1490/3)*3.14 = 1559.5333 cubic cm

Here's what my calculator shows when computing the expression.

Answer: The overall average of the weights is 24 pounds.

Step-by-step explanation:

To find the overall average of the weights, we need to calculate the weighted mean. A weighted mean is a type of average that takes into account the number of items or observations in each group.

In this case, we know that the average of the first 3 weights is 20 pounds and the average of the next 12 weights is 25 pounds.

To find the overall average, we will use the following formula:

( (number of items in first group * average of first group) + (number of items in second group * average of second group) ) / (number of items in first group + number of items in second group)

The formula can be applied as:

The center and vertices of the ellipse x² + 9y² + 16x - 54y + 136 = 0 is

Generally, The standard form of the equation of an ellipse is (x-h)^2/a^2 + (y-k)^2/b^2 = 1, where (h,k) is the center of the ellipse and a and b are the semi-major and semi-minor axes respectively.

To convert the given equation to standard form, complete the square by adding and subtracting constants to both sides: x² + 16x + 81 + 9y² - 54y + 324 = 410

This results in: (x + 8)²/16 + (y - 3)²/9 = 1

Therefore, the center of the ellipse is (h,k) = (-8,3) and the semi-major and semi-minor axes are a = 4 and b = 3.

To find the vertices of the ellipse, substitute the center coordinates into the equation of the ellipse and solve for x and y. Since the semi-major and semi-minor axes are 4 and 3, respectively, the vertices are located at: (h ± a, k) = (-8 ± 4, 3) and (h, k ± b) = (-8, 3 ± 3)

Therefore, the vertices of the ellipse are (-12,3) and (-4,3), (-8,6) and (-8,0).

Since the line segment RST is perpendicular to OM, the length of RT can be determined by using the Pythagorean Theorem.

Let RT = x

We know that:

x^2 = OS^2 + RT^2

x^2 = (7 cm)^2 + x^2

2x^2 = 49 cm^2

x^2 = 24.5 cm^2

x = √24.5 cm = 4.94 cm

Therefore, the length of RT = 4.94 cm
