Answer:

9 necklaces with 40 extra beads

Answer:

Step-by-step explanation:

850/90= 9 r40

Answer:

When we have a function f(x), the average rate of change in the interval (a, b) is:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

In this case, we have the function:

f(x) = (x + 3)^2 - 2

(but we do not have the interval, and I couldn't find the complete question online)

So if for example, we have the interval (2, 4)

The average rate of change will be:

[tex]r = \frac{(4 + 3)^2 - 2 - (2 + 3)^2 + 2}{4 - 2} = \frac{24}{2} = 12[/tex]

If instead, we want the rate of change in a differential dx around the value x, we need to differentiate the function (this is way more complex, so I will define some rules first).

Such that the rate of change, in this case, will be:

f'(x) = df/dx

For a function like:

g(x) = x^n + c

g'(x) = n*x^(n - 1)

And for:

h(x) = k( g(x))

h'(x) = k'(g(x))*g'(x)

So here we can write our function as:

f(x) = k(g(x)) = (x + 3)^2 - 2

where:

g(x) = x + 3

k(x) = x^2 - 2

Then:

f'(x) = 2*(x + 3)*1 = 2*x + 6

That is the rate of change as a function of x (but is not an "average" rate of change)

Answer:

72

Step-by-step explanation:

When you multiply 9 and 5 you get 45. When you subtract 6 from 24 you get 18.

45 + 18 = 72

If helpful please mark me brainliest!

The correct expression for the sum of the product of 9 and 5 and the difference of 24 and 6 will be (9 × 5) + (24 -6) which will be equal to 63.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations.

A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the given statement in the question,

Product of 9 and 5 i.e., 9 × 5 and,

Difference of 24 and 6 i.e., 24 - 6

Thus sum will be,

(9 × 5) + (24 - 6)

The result of the expression is 63.

Answer:

Equation: -3x + 18

Hope this helps!

Answer:

65.45

Step-by-step explanation:

Zscore = (x - mean) / standard deviation

x = score

Percentage below C :

D = 18% ; F = 12%

Sum = 30%

Obtain the Zscore for the proportion below D

P(Z < 0.30) = -0.524

Hence, Zscore = -0.524

Put Zscore = -0.524 in the equation :

-0.524 = (x - 72) / 12.5

-0.524 * 12.5 = x - 72

-6.55 = x - 72

-6.55 + 72 = x

x = 65.45

To receive a grade of C or better, score must be atleast 65.45

Answer:

p=60 and k=120

Step-by-step explanation:

So, with supplementary angles, there is a max of 180 degrees (because it is half of a circle.) With this information, we can make an equation. Let's make it.

If the measure of k is twice of p, then k=2p

Equation= 2p+p=180

Now let's isolate p and find out what it is!

2p+p=3p so...

3p=180

Now let's divide 3 on both sides.

That would equal...

p=60

That means p=60 for sure. However, since k is twice of p, we need to double p to find out what k is.

60 x 2=120

Final answer= p=60      k=120

Hope this helped!! If you have any questions, make sure to write them in the comments!

Answer:

k = 120

p = 60

Step-by-step explanation:

k = p2

p+p2 = 180

p3 = 180

p3/3 180/3

p = 60

k = 60 × 2

k = 120

Answer:

radius is 17

Step-by-step explanation:

Use "completing the square" to rewrite the given equation in standard form for a circle centered at (h, k) with radius r:

x^2+y^2-14x+10=250 becomes:

x^2 - 14x + y^2 = 240 after grouping x terms and  y terms separately.

Completing the square, once for x and once for y, results in:

x^2 - 14x + 49 - 49 + y^2 = 240.

Rewriting x^2 - 14x + 49 as the square of the binomial x - 7 results in:

(x - 7)^2 + y^2 = 289 = 17^2

From this we recognize that the center is at (7, 0) and the radius is 17.

Answer:

b = 20 cm.

Step-by-step explanation:

Define and explain:

This is a right triangle, so the Pythagorean Theorem applies.

The Pythagorean Theorem states that the sum of the squared legs will equal the squared length of the hypotenuse.

The legs of a triangle are the sides that form the right angle.

The hypotenuse is the longest side; the hypotenuse is always diagonal from the small square indicating a right angle.

Solve:

[tex]a^2+b^2=c^2[/tex]

[tex]a,b-legs[/tex]

[tex]c-hypotenuse[/tex]

[tex]15^2+b^2=25^2[/tex]

[tex]225+b^2=625[/tex]

[tex]625-225=400[/tex]

[tex]b^2=400[/tex]

[tex]b=20[/tex]

Conclude:

Therefore, the length of the unknown side is 20 centimeters.

Answer:

a. Area = 1,017.36 cm²; Circumference = 113.04 cm

b. Area

c. Circumference

Step-by-step explanation:

Given:

Radius (r) = 18 cm

π = 3.14

a. Area of the mirror = area of circle = πr²

Plug in the values

Area = 3.14*18²

Area = 1,017.36 cm²

Circumference = 2πr

Circumference = 2*3.14*18

Circumference = 113.04 cm

b. The area of the glass would be used in finding the amount of glass needed caused it's the surface of the glass that is to be replaced.

c. The silver wire would be placed around the mirror, therefore, it is the circumference that would be needed in finding the amount of wire needed since the circumference is the perimeter round the mirror.
