What is the volume of a figure with a length of 2m, a height of approximately 1/2 the length, and a width of 6m?

Answers

12m³ is your answer

Answer:

Given:

length[l]=2m

breadth or width [b]=6m

A sector has a radius of 12 centimeters and an angle of 65 degrees. Find it's arc length.

A. 18.2 cm
B. 13.6 cm
C. 12.6 cm
D. 14.6 cm

Answers

Answer is B

Because the formula for arc length is: 2pi (r) * angle/360

So if we input our values in the formula we have:

2pi (12) * 65/360

Just input this into your calculator and you get the answer as 13.6 (1.DP)

Hope this helped

The arc length will be option B. 13.6 cm.

How to find the relation between angle subtended by the arc, the radius and the arc length?

[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.

In 2 years, Duncan wants to buy a bicycle that costs $400.00. If he opens a savings account that earns 11% interest compounded annually, how much will he have to deposit as principal to have enough money in 2 years to buy the bike?

Answers

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.)

Which of the following are "like" terms: 6b 5x 4x x 2e

Answers

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.

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
