Answer:
Step-by-step explanation:
The triangles are similar.
(x-6)/3 = x/6
x = 15
Answer:
8.57 miles
Step-by-step explanation:
It is provided in the question that,
<em>Janice drove 360 miles in 6 hours.</em>
<em>Formula to calculate speed = distance / time</em>
Speed at which Janice drove = 360 / 6
= 60 miles/hours
<em>To find, </em>
<em>distance Janice will cover in 7 hours </em>
Distance = speed * time
Distance = 60miles/hour * 7 hours
Distance = 8.57 miles
So the distance Janice travel i 7 hours at 60miles/hr is 8.75miles
Ni : Zn: Cu = 7:2:9 =7x : 2x : 9x
7x+2x+9x = 3.8
18x=3.8
x=3.8/18=1.9/9≈0.21
Ni: 7x=7*0.21=1.47 ≈1.5 kg
Zn: 2x=2*0.21=0.42≈0.4 kg
Cu: 9x=9*0.21=1.89 ≈1.9 kg
Check 1.5+0.4+1.9 =3.8 True
There are many ways to answer this. Here is one answer shown below
AB/WX = BC/XY
On the left side is the ratio of AB over WX. These two sides are the bottom horizontal portions of the triangles. This is a visual indication that they correspond to one another. More concrete proof of this is that AB and WX are the first two letters of the sequences ABC and WXY respectively. The order is very important to help establish pairs like this.
On the right side of that equation above, we have BC and XY as the diagonal sides on the right part of each triangle. They are the last two letters of ABC and WXY respectively, which is a non-visual way to prove these two sides correspond.
It might help to line up ABC over top WXY so you can pick out the corresponding sides. I show this in the attached image below.
