Answer:
b i think
Step-by-step explanation:
Recall that distance = speed times time. Thus, time = distance / speed.
Here:
time = distance / speed = 0.8 km / 12 km/hr = 1/15 hr.
Note that 1/15 hr = 1/15 (60 min) = 4 minutes
You just need to plot them on a graph and see how many spaces are in between each. So if you plot (1,9) remember it's X, Y axis. Start from zero on the graph. Since it's positive go over 1 to the right and up 9. Then do the same for the rest. Then count how many units are between each point on the graph and find the one that is 5 units apart.
The total number of common tangents that can be drawn to the circles is 2.
<h3>What is a tangent?</h3>
A tangent serves as line that touches the circle at a single point whereby the point where tangent meets the circle is the tangency.
A tangent to a circle can be described as the straight line that touches the circle at only one point.
Therefore, from the definition, The total number of common tangents that can be drawn to the circles is 2.

Answer:
The number is infinity
Step-by-step explanation:
Let the unknown number be x
if the number increased by three, then we have;
x + 3
Also quadrupling that number increased by five all divided by four is expressed as;
(4x+5)/4
Equating bith expressions and calculating x;
x+3 = (4x+5)/4
cross multiply;
4(x+3) = 4x + 5
4x+12 = 4x + 5
4x-4x = 5 - 12
0x = -7
x = -7/0
x = ∞
Hence the number is infinity
