Sophie and Isadora ride around a circular track that has an inner radius of 30 m. The track is 2 m wide and Isadora rides along
Naddika [18.5K]
It’s just the difference in circumferences, so it’d be
S = 2 Pi r
S = 2 * 3.14 * 30
S = 188.4m

I = 2 Pi r
I = 2 * 3.14 * (30 + 2)
I = 200.96m

I - S = 200.96 - 188.4
= 12.56m

Therefore, Isadora had to ride 12.56m more than Sophie

Complete the description of what happens to a figure when the given sequence of transformations is applied to it: (x, y) + (-x,y
Len [333]

Answer:

  • reflection over the y-axis;
  • dilation with a scale factor of 0.4;
  • translation 8 units left and 8 units up

Step-by-step explanation:

<h3>Reflection</h3>

The first transformation changes the sign of the x-coordinate. That means a point that was some number of units (3, for example) <em>right</em> of the y-axis will be transformed to a point 3 untis <em>left</em> of the y-axis. It is reflected across the y-axis.

__

<h3>Dilation</h3>

The second transformation multiplies each coordinate value by 0.4. A point that was some number of units (3, for example) away from the origin, will be transformed to a point 3×0.4 = 1.2 units from the origin. It is dilated by a factor of 0.4.

__

<h3>Translation</h3>

The third transformation subtracts 8 from the x-coordinate and adds 8 to the y-coordinate. The x-coordinate is a measure of the distance to the right of the y-axis, so subtracting 8 from the x-coordinate means the point is 8 fewer units to the right of the y-axis. It is translated left 8 units.

Similarly, the y-coordinate is a measure of the distance up from the x-axis. Adding 8 to the y-coordinate will move the point 8 more units up from the x-axis. It is translated up 8 units.

Anyone good with fractions?? All I need is someone to explain how to get the answer to this problem. I can't figure it out.
AURORKA [14]
Don’t worry! Fractions aren’t my thing either but here’s how to solve it:

First do 54 1/3 - 15 2/3 = 38 2/3. Then do 38 2/3 divided by 3 1/3 = 11 3/5. Rounded, Olivia will spend 11 day. Hope this helps!!

The perimeter of an equilateral triangle is 18p - 24. Write an expression to represent the length of each side.
grandymaker [24]

Answer:

  6p -8

Step-by-step explanation:

The three sides of an equilateral triangle are all the same length. (This is the literal meaning of "equilateral.") So, the length of one side is 1/3 the total length.

each side = \dfrac{18p-24}{3}=\dfrac{18p}{3}-\dfrac{24}{3}=6p-8
