IMPORTANT!! in a unit circle, what is the relationship between arc length and central angle?

1 answer:

Answer:

The measure of an arc refers to the arc length divided by the radius of the circle. The arc measure equals the corresponding central angle measure, in radians. That's why radians are natural: a central angle of one radian will span an arc exactly one radius long.

Rasheed bought two kinds of candy bars, chocolate and toffee, that came in packages of 2 bars each. He handed out 2/3 of the cho

mylen [45]

Answer:

Rasheed bought 9 packages of chocolates bar.

Step-by-step explanation:

Let C be the number of packages of chocolate bars.

Let T be the number of packages of toffee bars.

Rasheed handed out 2/3 of 2C of the chocolate bars and 3/5 of 2T of the toffee bars.

(1) Rasheed bought 1 fewer package of chocolate bars than toffee bars.

Equation becomes:

$C=T-1$ .....(1)

(2) Rasheed handed out the same number of each kind of candy bar .

Equation becomes:

$\frac{2}{3}\times 2C =\frac{3}{5}\times 2T$

=> $\frac{4C}{3} =\frac{6T}{5}$

=> $20C=18T$

=> $20C-18T=0$

Taking out 2 common, we get

$10C-9T=0$ ......(2)

Substituting $C=T-1$ in (2)

$10(T-1)-9T=0$

=> $10T-10-9T=0$

=> $T-10=0$

T = 10

As $C=T-1$

$C=10-1$

C = 9

Therefore, Rasheed bought 9 packages of chocolates bar.

Let x = # of weeks passed

Algebraic Expression: 141 - 14x =

Week 1: 141 - 14 = 127

Week 2: 141 - 14(2) = 113

Week 3: 141 - 14(3) = 99

A rectangular garden has an area of 154 square feet. If its width is 11 feet, what is its length?

kakasveta [241]

Answer:

$Width = 14feet$

Step-by-step explanation:

Given

$Area = 154$

$Width = 11$

Required

The length

Area is calculated as:

$Area = Length * Width$

Make Width, the subject

$Width = \frac{Area}{Length}$

So, we have:

$Width = \frac{154}{11}$

$Width = 14feet$
