Answer:
The actual distance between the two houses is:
3.2 km
Step-by-step explanation:
Proportions:
1cm ⇔ 100000 cm
3.2 cm ⇔ W cm
W = 3.2*100000/1
W = 320000 cm
1 km = 100000 cm
320000cm = 320000/100000 = 3.2km
I'll do problem 12 to get you started
----------------------------------------
Part (a)
The ratio 3:6:7 means the three sides are 3x, 6x and 7x centimeters long. The x is some positive real number.
The longest side is 7x, which is also 16.1, so 7x = 16.1
Divide both sides by 7 to isolate x
7x = 16.1
7x/7 = 16.1/7
x = 2.3
Now we can calculate the other two sides
3x = 3*2.3 = 6.9
6x = 6*2.3 = 13.8
<h3>The other two sides are 6.9 cm and 13.8 cm</h3>
----------------------------------------
Part (b)
Add up the three sides to get
6.9 + 13.8 + 16.1 = 36.8
<h3>The perimeter is 36.8 cm.</h3>
A line that has a 0 slope is a horizontal line.....it is represented by y = a number.....so a line with a zero slope WILL touch the y axis.....it will touch the y axis at y = 1
just so u know...it is a vertical line that does not touch the y axis
so ur answer is y = 1.....this line has no slope but it touches the y axis
