Answer:

3 x 4 = 12 erasers   12 x $0.72 = $8.64

Step-by-step explanation:

Answer: Skye will need $8.64

Step-by-step explanation:

We can start by seeing how many erasers she needs in total. We can multiply the 3 erasers for all 4 of her friends.

3 x 4 = 12 Erasers

Now we multiply the cost of one eraser by the total amount she needs, 12.

0.72 x 12 = 8.64

So the amount of money Skye needs for all her friends to have 3 erasers is $8.64

Answer:

The perimeter of a rectangle is the sum of all of it’s sides. Since a rectangle has 2 lengths of the same size and two widths of the same size, the perimeter is length + length + width + width, or 2(length) + 2(width), or, to make it shorter, 2l + 2w.

Since the length of the rectangle (l) in this scenario is really 4w, we can replace those, and get 2(4w) + 2w, and since we know the total is 50, we can say 2(4w) + 2w = 50.

Using the distributive property, we get 8w + 2w = 50, and 10w = 50, or w = 5. Since the length is 4w, the length is 4*5 = 20.

To find the area, you multiply length and width to get 5 * 20 = 100 sq meters.

Using the Newton method, the next estimate of the height after one iteration is: h = 0.1474m.

-----------------------------------

The Newton's method to find a solution [tex]x[/tex] of a function [tex]f(x)[/tex] is given by:

[tex]x_{n+1} = x_n - \frac{f(x_n)}{f^{\prime}(x_n)}[/tex]

In which n+1 is the next iteration.

-----------------------------------

In the context of this problem, the height is:

[tex]h_{n+1} = h_n - \frac{V(h_n)}{V^{\prime}(h_n)}[/tex]

Thus, for the first iteration:

[tex]h_1 = h_0 - \frac{V(h_0)}{V^{\prime}(h_0)}[/tex]

-----------------------------------

The function, and its derivative, are:

[tex]V(h) = \frac{3r \pi h^2 - \pi h^3}{3}[/tex]

The radius is [tex]r = 3[/tex], thus:

[tex]V(h) = \frac{9\pi h^2 - \pi h^3}{3}[/tex]

[tex]V^{\prime}(h) = \frac{18\pi h - 3\pi h^2}{3}[/tex]

Simplifying by 3:

[tex]V^{\prime}(h) = \pi(6h - h^2)[/tex]

-----------------------------------

The initial estimate is [tex]h_0 = 0.3[/tex], thus:

[tex]V(0.3) = \frac{9\pi (0.3)^2 - \pi (0.3)^3}{3} = 0.82[/tex]

[tex]V^{\prime}(0.3) = \pi[6(0.3) - (0.3)^2] = 5.3721[/tex]

-----------------------------------

The estimate, after 1 iteration, is:

[tex]h_1 = h_0 - \frac{V(h_0)}{V^{\prime}(h_0)}[/tex]

[tex]h_1 = 0.3 - \frac{0.82}{5.3721}[/tex]

[tex]h_1 = 0.1474[/tex]

The estimate of the height after one iteration is of h = 0.1474m.

Answer:

-16/10

Step-by-step explanation:

It's already an improper fraction.

Answer:

-8/5

Step-by-step explanation:

To simplify, you have to divide the numerator and denominator by  the same number. In this case, it's 2.

I hope I helped!

We can't simplify anymore, because -8 is composite and 5 is prime :-)

Answer:

990 cookies in one crate and 2880 cookies in all three crates combined.

Step-by-step explanation:

In each of the three crates are 24 boxes. First, let's find the number of boxes by multiplying:

3 crates x 24 boxes

3 x 24

72

So we have 72 boxes of cookies. Now we must complete the final step in order to calculate the number of cookies. We will do so by once again multiplying.

72 boxes x 40 cookies

72 x 40

2880

In total, that is, including all the cookies from all the boxes in all three crates, we have 2880 cookies.

The questions seems to ask how many cookies are in one crate, however. In order to find that, we must simply divide the number of cookies, 2880, by the number of crates, 3.

2880 cookies ÷ 3 crates

2880 ÷ 3

960

Therefore, there are 990 cookies in one crate and 2880 cookies in all three crates combined.

Answer: To rationalize the denominator, you must remove any radical expressions in it, such as square roots and cube roots. The key concept is to multiply the original fraction by an appropriate number so that the denominator no longer contains radicals after simplification.

-13  ≤ x  ≤ 11

Step-by-step explanation:

|x+1| ≤12

There are two solutions, one positive and one negative, remembering to flip the inequality for the negative

x+1 ≤12     x+1 ≥-12

Subtract 1 from each side

x+1-1 ≤12-1   and   x+1-1 ≥-12-1

x ≤11   and     x ≥-13

-13  ≤ x  ≤ 11

Answer:

36 is the final value for the equation you posted

Step-by-step explanation:

We are told that = 3 and = −2.

Let's plug these values into the equation.

= (5 ( − 2) + (2 − )^2)

= (5 (3 − 2(−2)) + (2 − 3)^2)

= (5 (3 + 4) + (−1)^2)

= (5 (7) + 1)

= 35 + 1

= 36

Step-by-step explanation:

C is at x=1 at circle side is at 8

8-1= 7

so, r=7

Answer:

The radius of the circle is 7 units.

Step-by-step explanation:

Radius is the measure from the center point of a circle to a point on the outside edge. Since you have coordinates, you can find the radius using distance formula.

You could also just count how many units are between the center and the edge to get 7 units because 8 - 1 = 7

SORRY IF I AM WRONG

Answer:

23.8 years

Step-by-step explanation:

Assuming this is compound interest, we'll use the compound interest formula

A = P(1 + r)ⁿ

A = Final amount (2000)

P = Initial amount (500)

r = Annual interest rate (.06)

n = ?

Our equation will look like this

2000 = 500(1.06)ⁿ

First, divide both sides by 500

2000/500 = (500(1.06)ⁿ)/500

(1.06)ⁿ = 4

Then we have to take the log₁.₀₆ out of both sides

n = log₁.₀₆(4)

n = 23.79132
