Answer:

2886.34 mm

Step-by-step explanation:

The radius of the disc is given to be 35 millimeters. This means that the distance from the edge of the large circle to the center is 35 millimeters.

We need to find the large circle area and subtract the small circle area from it.

Large circle area:

Area = πr^{2}

        = π(35 mm)^{2}

        = 1225π

The radius of the small circle is half the radius of the large circle. 35/2 = 17.5

Small circle area:

Area = πr^{2}

        = π(17.5 mm)^{2}

        = 306.25π

Large circle - small circle =

1225π - 306.25π = 918.75π

                            = 2886.3<u>4</u> mm

Answer:

3848.45mm

Step-by-step explanation:

Area = \pi r^{2}

35^{2} = 1225

1225 * \pi = 3848.45

Answer:

y-k

x-h

Step-by-step explanation:

Given E &D, F would be at (x, k).

That means E to F would be y-k.

And F to D would be x-h.

I assume you don’t need to find E to D, since that’s just r. (You could use the Distance Formula or Pythagoreans theorem to come up with and equation, but it wouldn‘t be one of those listed.)

The first two numbers in a sequence h are h(1) = 2 and h(2) = 6.
Ghella [55]

Answer:

Step-by-step explanation:

Given the first two numbers of a sequence as 2, 6...

If it is an arithmetic difference, the common difference will be d = 6-2 = 4

Formula for calculating nth term of an ARITHMETIC sequence Tn = a+(n-1)d

a is the first term = 2

d is the common difference = 4

n is the number if terms

Substituting the given values in the formula.

Nth term Tn = 2+(n-1)4

Tn = 2+4n-4

Tn = 4n-4+2

Tn = 4n-2

2) If the sequence us a geometric sequence

Nth term of the sequence Tn = ar^(n-1)

r is the common ratio

r is gotten by the ratio of the terms I.e

r = T2/T1

r = 6/2

r = 3

Since a = 2

Tn = 2(3)^(n-1)

Hence the nth term of the geometric sequence is Tn = 2(3)^(n-1)

A company sells two versions of an antivirus software. The home edition costs $23.50, and the business edition costs $58.75. Las
Kamila [148]

Answer:

x + y = 745

23.50x + 58.75y = 29,668.75

Step-by-step explanation:

Since 745 copies were sold and  x represents the number of copies of the home edition sold and y represents the number of copies of the business edition sold:

x + y = 745

Since the home edition costs $23.50, and the business edition costs $58.75:

The money earned from home edition is = 23.50x

The money earned from business edition is = 58.75y

Since the company earned $29,668.75:

23.50x + 58.75y = 29,668.75

John needs to cut three strips of wood, 25.5 cm, 15.3 cm, and 9.25 cm long. He has a strip that is 72 cm long. How long will the
NeX [460]

Add the three strips of cut wood together:

25.5 + 15.3 = 40.8

40.8 + 9.25 = 49 + 1.05 = 50.05

John will need to cut a total of 50.05cm of wood.

Subtract this total from the strip John has:

72 - 50.05 = 22 - .05 = \boxed{21.95}

The leftover piece will be 21.95cm long.
