Answer:

8\:\mathrm{cm}

Step-by-step explanation:

By definition, the length arc is a portion of a circle's circumference. The exact amount is directly proportional to the measure of the arc. Therefore, the formula for the length of an arc with measure (in degrees) \theta is 2\pi r\cdot \frac{\theta}{360}, where 2\pi r is the circumference of the circle.

Substituting 2\pi r=18 and \theta=160^{\circ}:

L_{arc}=18\cdot \frac{160}{360}=\boxed{8\:\mathrm{cm}}

During gym class, Lenny, Lonnie, and Lainey measure the length of their long jumps. Lenny’s jump is ⅔ times the length of Lainey
Svetllana [295]

Answer: Lonnie’s Jump

Step-by-step explanation:

         (They just <em>had</em> to give three names that all started with L.)

         Since Lenny's jump is ⅔ times the length of Lainey’s, we can tell that Lenny's jump won't be the longest because it is already smaller than Lainey's.

         Since Lenny is now out of the picture, let us look at Lonnie and Lainey. Lonnie’s jump is 1 ⅓ times the length of Lainey’s. Since Lonnie's jump is longer than Laniey's, Lonnie's jump is the longest jump.

Answer:

12.

Step-by-step explanation:

This is how to round 12.36 to the nearest whole number. In other words, this is how to round 12.36 to the nearest integer.

12.36 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:

Integer Part: 12

Fractional Part: 36

Our goal is to round it so we only have an integer part using the following rules:

If the first digit in the fractional part of 12.36 is less than 5 then we simply remove the fractional part to get the answer.

If the first digit in the fractional part of 12.36 is 5 or above, then we add 1 to the integer part and remove the fractional part to get the answer.

The first digit in the fractional part is 3 and 3 is less than 5. Therefore, we simply remove the fractional part to get 12.36 rounded to the nearest whole number as:

12

babymother [125]

Answer:

The Equation is

4x+2y= 200

Then total number of candy bars is

X+Y

Step-by-step explanation:

Shelby made $200 from selling x at $4 each and y at $2 each.

Let's have in mind that x is the number of large candy bars

And y is the number of small candy bars

The equation is simple

The amount it was sold is going to be the coefficient of the numbers we don't Know...

So

Equation is

4x+2y= 200

Then total number of candy bars is

X+Y
