Bert is making a bracelet with green and blue beads. He uses green beads for the first 6
centimeters. Now, he wants to add blue beads to the bracelet so the total length is 20
centimeters. If each blue bead has a width of 7 millimeters, how many blue beads will he use
to finish the bracelet?

Answer:

4

Step-by-step explanation:

The diameter of a circle is 2 times the radius. (the diameter is the length from an outer point in  the circle, to one directly across)

In this case, the radius is 2.

So, 2 x 2 = 4.

The diameter is 4.

4 in

The diameter of a circle is twice its radius. Here the given radius is 2 in.

So diameter = 2 in × 2 in = 4 in

Radius = Diameter/2

Diameter = Radius × Radius

Answer:

20.4375 miles

Step-by-step explanation:

 5 miles / 8 km    *    32.7 km   = 20.4375 miles

    ( see how the units 'km' cancel out and you are left with 'miles' as your answer?)

The equation of the graphed function is [tex]y = 3\sec(\frac{\pi}{3}x) + 2[/tex]

The graph is a secant graph, and it has the following form

[tex]y = a\sec(bx) + c[/tex]

From the graph, we have the following parameters:

The amplitude (a) is calculated using:

a = 0.5 *(Local minimum - Local maximum)

a = 0.5 *(5 + 1) = 3

The vertical shift (c) is calculated using:

a = 0.5 *(Local minimum + Local maximum)

a = 0.5 *(5 - 1) = 2

The period (b) is calculated using:

[tex]b = \frac{2\pi}{T}[/tex]

This gives

[tex]b = \frac{2\pi}{6}[/tex]

Evaluate

[tex]b = \frac{\pi}{3}[/tex]

Substitute the values of a, b and c in [tex]y = a\sec(bx) + c[/tex]

[tex]y = 3\sec(\frac{\pi}{3}x) + 2[/tex]

Hence, the equation of the graphed function is [tex]y = 3\sec(\frac{\pi}{3}x) + 2[/tex]

Answer:

The population after 10 years will be 90,000.

Explanation:

2% of 75,000 is 1,500

the population will grow by 1,500 each year.

so 1,500 times 10 is 15,000

so than we add 75,000 + 15,000

we get the answer of 90,000.

Please mark me brainliest. Thank you.

Answer:

91425 population

Answer:

A.  7x + 3

Step-by-step explanation:

The perimeter of a 2D shape is the distance all the way around the outside.

⇒ perimeter = (2x + 1) + (x + 1) + (3x - 1) + (x + 2)

                     = 2x + 1 + x + 1 + 3x - 1 + x + 2

                     = 2x + x + 3x + x + 1 + 1 - 1 + 2

                     = 7x + 3

Step-by-step explanation:

The length of the rectangular garden which Travis drew on graph is equal to the large side of the rectangle made by four points and width is equal to short side.

The measure of the boundary of the sides of a rectangles called its perimeter. The perimeter of a rectangle is twice the sum its length and width.

P=2(l+w)

Here, (l) is the length of the rectangle and (w) is the width of the rectangle.

Travis drew a graph to plan the rectangular garden he has. The points over the graph marked are the four corners of the fence around the garden.

Now let suppose the two corner marked are with total distance of x while other two with total distance of y. Then the length will be x and width will be y.

Thus, the length of the rectangular garden which Travis drew on graph is equal to the large side of the rectangle made by four points and width is equal to short side.

A number is an arithmetic value that is used to represent a quantity and calculate it. The two numbers will be 17 and 0, so the product of the two is minimal.

A number is an arithmetic value that is used to represent a quantity and calculate it. Numericals are written symbols that represent numbers, such as "3."

Given the difference between the two numbers is 17. Let the first number be zero, then the second number will be 17. Thus, the product of the two numbers will be 0, which is the minimum.

If the first number is further increased such as 1, then the other number will be 18, and the product of the two will be 18, which is greater than zero.

Hence, the two numbers will be 17 and 0, so the product of the two is minimal.

Answer:

-14/3

Step-by-step explanation:

Use derivative = 0 to find turning point(S)

D f(x) = 3x + 10 = 0

3x = - 10

X = - 10/3

When X = - 10/3

F(x) = 1.5(10/3)^2 - 10(10/3) + 12

= (3*10*10) / (2*3*3) - 100/3 +12

= 50/3 - 100/3 + 36/3

= - 14/3

The population at the end of the 10 years is 6,500.

Given that,

A town with a population of 5,000 grows 3% per year.

We need to find the population at the end of 10 years.

Based on the above information, the calculation is as follows:

= 5,000 + 1,500

= 6,500

Therefore we can conclude that the population at the end of the 10 years is 6,500.

Step-by-step explanation:

this is a combined object :

there is the basic block at the bottom (21×21×17), and there is a pyramid on top of it.

so, we need to calculate the volume of both parts and add them for the total volume.

the volume of the block is, as mentioned :

21 × 21 × 17 (length×width×height) = 7,497 ft³

the volume of a pyramid is

length×width×height/3

which is in our case

21 × 21 × 9 / 3 = 21 × 21 × 3 = 1,323 ft³

so, the total volume is

7,497 + 1,323 = 8,820 ft³
