A timer rings every half hour for 3 1/2 hours.
Use your model to determine the number of rings.
dont make me feel like that was a waste

Answers

Answer 1

Answer:

7 times

Step-by-step explanation:

So since it rings every half hour, there should be 2 rings every hour, if not you are not on our planet. (60 mins in an hour, 30 mins = 1, so 60 mins =2)

So since it rings for 3 full hours, we get an initial step of 3 * 2 = 6 rings

Then there is another 1/2 ring because 3 and a 1/2 hours. So 6+1=7

hope i helped :) im not sure what you mean by model :(

Step-by-step explanation:

What this question is asking us to do is to find the area of the square and the rectangle individually and then add them together to find the total area of the whole rectangle.

Firstly, let us find the area of each of the rectangles.

Let us start with the light-blue square. It has side lengths x and x

This means that the area of this square is [tex]x*x=x^2[/tex]

Now the dark blue rectangle. It has sides with lengths x and 1.

This means that the area of this rectangle is [tex]x*1=x[/tex]

Now that we have the area of each of the rectangles, we can add them together to get the area of the whole rectangle

Answers

Answer:

7 weeks

Step-by-step explanation:

Leanne is trying to convert x^2+4x-6=0 the standard form to vertex form by completing the square which equation shows the correct form

Answers

Answer:

In vertex form we have y =      (x + 2)^2 - 10

Step-by-step explanation:

x^2+4x-6=0 is in standard form; we want it in the form y - k = a(x - h)^2.

Complete the square within  x^2+4x-6=0

We get  x^2 + 4x - 6 = 0  =>  x^2 + 4x + 4 - 4 - 6, or

                                          y =      (x + 2)^2 - 10

Comparing this to              y = (x - h)^2 - 10, we see that the vertex is at

                                            (h, k) :  (-2, -10)

Answer: [tex](x+2)^2-10=0[/tex]

Step-by-step explanation:

[tex]x^2+4x-6=0[/tex]

Let 0 = y to not mix up the numbers.

[tex]x^2+4x-6=y[/tex]

we are trying to get to this form: [tex]y=a(x-h)^2+k[/tex]

Let's group the variables to make it easier for us to complete the square.

[tex](x^2+4x)-6=y[/tex]

Complete the square by taking the number next to the x variable (4) divide it by 2 (4/2=2) and square it ([tex]2^2=4[/tex])

Add this.

[tex](x^2+4x+4)-6=y[/tex]

You also have to add it to the right side, but since we're looking to isolate y again, we're going to have to move it to the left side eventually; therefore, we can simply change the sign and add it to the left side.

In other words, instead of doing this:

[tex]-6=y+4\\-6-4=y[/tex]

I'm going to directly say the opposite of +4 is -4

[tex](x^2+4x+4)-6-4=y[/tex]

Now factor the parentheses and combine like terms;

[tex](x+2)^2-10=y[/tex]

And like we said y = 0, so change that...

[tex](x+2)^2-10=0[/tex]

What is the volume of this rectangular prism?
-
4.8 cm
4.1 cm
15 cm

Answers

Answer:

295.2 cm^3

Step-by-step explanation:

Volume of a prism = length * width * height.

Here the volume = 4.8 * 4.1 * 15

= 295.2 cm^3.

The volume of rectangular prism is 295.2[tex]cm^{3}[/tex]

What is rectangular prism?

A rectangular prism is a polyhedron with two congruent and parallel bases. It is also called a cuboid. A rectangular prism has six faces, and all the faces are in a rectangle shape and have twelve edges. Because of its cross-section along the length, it is said to be a prism.

What is the volume of rectangular prism?

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

According to question

Length of rectangular prism = 4.8cm

Breath of rectangular prism = 4.1cm

Height of rectangular prism = 15cm

Volume of rectangular prism = Length * Breath * height

= 4.8*4.1*15

= 295.2[tex]cm^{3}[/tex]

Hence, Volume of rectangular prism is 295.2[tex]cm^{3}[/tex]

Solve the equation below.
3(17x – 6.5) = 108

Answers

Answer:

x=2.5

Step-by-step explanation:

3(17x – 6.5) = 108

Divide each side by 3

3/3(17x – 6.5) = 108/3

17x - 6.5 =36

Add 6.5 to each side

17x -6.5+6.5=36+6.5

17x = 42.5

Divide each side by 17

17x/17 = 42.5/17

x = 2.5

2) The Club Auto Parts Company has just recently been organized. It is expected to experience no growth for the next 2 years as it identifies its market and acquires its inventory. However, Club will grow at an annual rate of 5% in the third and fourth years and, beginning with the fifth year, should attain a 10% growth rate which it will sustain thereafter. The last dividend paid was $0.50 per share. Club has a cost of capital of 12%. What should be the present price per share of Club common stock?

Answers

Answer:

$20.84

Step-by-step explanation:

div 1 = $0.50

div 2 = $0.50

div 3 = $0.50 x 1.05 = $0.525

div 4 = $0.525 x 1.05 = $0.55125

years 5 and beyond we need to use the growing perpetuity formula:

stock price = [div 4 x (1 + g)] / (r - g) = ($0.55125 x 1.1) / (12% - 10%) = $30.32

now to determine the current value of the stocks we must calculate the present value of the future dividends and stock price:

stock price = $0.50/1.12 + $0.50/1.12² + $0.525/1.12³ + $0.55125/1.12⁴ + $30.32/1.12⁴ = $0.45 + $0.40 + $0.37 + $0.35 + $19.27 = $20.84

The science club sponsors is ordering caps and shirts for the boys and girls in the science club. There are 45 science club members. If the caps in some packages of 3 and the shirts come in packages of 5 what is the least number of packages of caps and church that will need to be ordered

Answers

Answer:

The least number of package of cap required is 15, while that of shirt is 9

Step-by-step explanation:

Total number of members = 45

The cap comes in package of 3

The shirt comes in package of 5

The least number of the package of caps they need to order is =?

Since they're 45 in numbers, we can divide 45 by 3 to know the total number of package required to go round.

Number of package of caps = 45 / 3

Number of package of caps = 15

We can also go ahead and find the number of package for shirt required by using the same method, only this time we'll divide it by 5 instead of 3

Number of package for shirt = 45 / 5

Number of package for shirt = 9

Therefore, the least number of package of caps required is 15 while that of shirt is 9

A square has an area of 9 cm^2. What is the length of each side?

Answers

Answer:

The side length is 3 cm

Step-by-step explanation:

The area of a square is given by

A = s^2  where s is the side length

9 = s^2

Take the square root of each side

sqrt(9) = sqrt(s^2)

3 =s

The side length is 3 cm

Answer:

3cm

Step-by-step explanation:

As we know it's a square, we can just square the area to get:

[tex]\sqrt{9}[/tex] = 3

We know we can do this as to find the area of a square or rectangle you just need to multiply the sides together. As it's a square, all the sides are the same so they have the formula:

Step-by-step explanation:

Un parallelepipedo rettangolo ha una dimensione di base di 15 cm e l'altra è i 35 della prima. L'area totale misura 750 cm2. Di L'area laterale; L'altezza del parallelepipedo; Il volume. calcola

Answers

Answer:

1. Suprafața laterală este de 480 cm²

2. Înălțimea paralelipipedului este de 4,8 cm

3. Volumul paralelepipedului este de 648 cm³

Step-by-step explanation:

Un paralelipiped dreptunghiular are dimensiunea bazei de 15 cm, iar celălalt este 35 din primul. Suprafața totală măsoară 750 cm2. Din zona laterală; Înălțimea paralelipipedului; Volumul. Calcol

Aici avem

Dimensiunile bazei sunt;

a = 15 cm

b = 3/5 × 15 = 9 cm

c = Obligatoriu

De asemenea suprafața totală = 750 cm²

∴ deoarece suprafața totală = 2 · a · b + 2 · b · c + 2 · a · c

2 × 15 × 9 + 2 × 35 × c + 2 × 15 × c = 750

270 + 70 · c + 30 · c = 750

100 · c = 480

c = 4,8 cm

Suprafața laterală reprezintă suprafața totală mai puțin zona de sus și de jos

Prin urmare;

1. Suprafața laterală = 750 - 2 × 15 × 9 = 480 cm²

2. Înălțimea paralelipipedului = c = 4,8 cm

3. Volumul paralelipipedului = aria bazei × înălțimea

∴ Volumul paralelipipedului = 15 × 9 × 4,8 = 648 cm³.

5 rides, cost of $15

Step-by-step explanation:

With the information given we have two expressions:

10 + 1x and 5 + 2x

Using these expressions we can create this equation:

10 + 1x = 5 + 2x

Knowing some information we can can simply analyze some information:

The closest number each of these equations could equal is 15,

1(5) is 5 + 10 = 15, and 2(5) is 10 + 5 = 15

15 = 15 this is a true statement, so we know this is answer
