The digit 3 in which number represents a value of 3 tens ?

The arc length will be option B. 13.6 cm.

[tex]2\pi^c = 360^\circ = \text{Full circumference}[/tex]

If radius of the circle is of r units, then

[tex]1^c \: \rm covers \: \dfrac{circumference}{2\pi} = \dfrac{2\pi r}{2\pi} = r\\\\or\\\\\theta^c \: covers \:\:\: r \times \theta \: \rm \text{units of arc}[/tex]

The superscript 'c' shows the angle measured in radians.

Given; A sector has a radius of 12 centimeters and an angle of 65 degrees.

So we input our values in the formula:

2π (12) x 65/360

= 24π x 65/360

= 13.6

Hence, the arc length will be option B. 13.6 cm.

Answer:

5x, 4x and x.

Step-by-step explanation:

Like Terms. "Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other. So say we have 4,5,and 3x. 4 and 5 would be like terms because they are just whole numbers. If we added another number with a coefficient of x, it would be 3x's like term. It's not as simple though, because a number having letters doesn't just make it a like term. It has to be the same letter(s). 4x and 5y are not like terms but 4x and 5x would be. 4xy and 5yz are not like terms but 5yz and 6yz would be like terms.

Hope this helps!

Answer:

x=30. y=60

Step-by-step explanation:

DG is a straight segment so it sums to 180 degrees. ECG is a right angle so 90 degrees. The rest is described as 2x and x. So 3x=90 degrees. x=30. Eh is also a straight segment. since we know x, we know that ECD is 60 degrees. So y+y=120 degrees. 2y=120. y=60.

Answer:

10 g

Step-by-step explanation:

40/2 = 20 g

20/2 = 10 g

If half-life of a radioactive kind of tellurium is 2 months. If you start with 40 grams of it, then 10 gm of it left after 4 months.

Half-life is the time required for a quantity to reduce to half of its initial value.

Given,

The half-life of a radioactive kind of tellurium is 2 months

It started with 40 grams of radioactive kind of tellurium

As given, half is for two months

In first two months it becomes 20 gm

40/2= 20gm

In second two months the 20 gm is reduced by half

20 gm/2=10gm.

Hence, 10gm of radioactive kind of tellurium is left after 4 months.

Answer:

Current deposit amount  = $324.65 (Approx.)

Step-by-step explanation:

Given:

Cost of bicycle = $400

Future amount = $400

Rate of interest = 11% = 0.11

Number of year = 2 year

Find:

Current deposit amount

Computation:

Compound interest formula

A = P[1+r]ⁿ

Future amount = Current deposit[1+Rate of interest]ⁿ

400 = Current deposit[1+0.11]²

400 = Current deposit[1.11]²

400 = Current deposit[1.2321]

Current deposit amount  = 400 /1.2321

Current deposit amount  = $324.65 (Approx.)

Answer:

  30.85 in

Step-by-step explanation:

The circumference of a circle with a 6" radius is ...

  C = 2πr

  C = 2π(6 in)

Then the curved portion of a semicircle with that radius will have the length ...

  1/2C = 1/2(2π)(6 in) = 6π in . . . . curved length

The straight portion of the boundary of this figure is simply twice the radius, so is ...

  2×6 in = 12 in . . . . straight length

__

The perimeter is the sum of the curved and straight lengths:

  P = (6π +12) in ≈ 30.8496 in ≈ 30.85 in . . . . figure perimeter
