Answer:
2 miles
Step-by-step explanation:
We can use ratios to solve this problem
3/4 miles x miles
--------------- = ---------------
3/8 hours 1 hours
Using cross products
3/4 * 1 = 3/8 * x
Multiply by 8/3 to isolate x
3/4 * 8/3 = 3/8*8/3 *x
8/4 = x
2 =x
Answer:
One
Step-by-step explanation:
It is one because each spoke has one space in the middle. However some people think it's 64 because they read the question wrong.
Answer:
Translation and dilation.
Step-by-step explanation:
<em>Figure 1</em> shows Circles A (red) and B (blue) before any transformations.
<em>Step 1</em>. Translate the centre of circle A from (4,5) to (1,7).
The circles are now concentric <em>(Fig. 2)</em>.
Step 2. Dilate the radius of Circle A by a factor of 9/3.
r₁×9/3 ⟶ r₂, so every point of the dilated circle coincides with an identical point on Circle B <em>(Fig. 3).
</em>
The translation, followed by a dilation with scale factor r₂/r₁, mapped Circle A onto Circle B, so <em>the two circles are similar</em>.
