In order to determine the actual distance between the two towns, multiply the distance between the two towns in the map, 5.5 in by the scale on the map. It is noted in the map that per inch distance corresponds to 0.5 mi. The product of 5.5 in and 0.5 mi/in is 2.75 miles. Thus, the actual distance between the towns is 2. 75 miles.
Answer: 8-x•x=20
Step-by-step explanation: i’m not sure if this is the answer sorry if it’s wrong!
Answer:
The formula T= 10d +20
A) what does each term on the right side of the equation represent?
- 10d⇒ 10 degrees increase per 1 km and 20 deg surface temperature
B) Estimate the depth where the temperature is 60 degrees C.
C) What is the approximate temperature at a depth of 4km?
The coordinates of B are (3, -8). Where the line-segment AB has the midpoint at M with coordinates (2, -1).
<h3>How to calculate the midpoint?</h3>
The midpoint on a line segment with two endpoints (x1, y1) and (x2, y2) is
Midpoint (x, y) = (
,
)
<h3>Calculation:</h3>
The given line segment is AB with coordinates A(1, 6) and B(x2, y2).
M is the midpoint of line segment AB. Its coordinates are M(2, -1)
Then, the coordinates of B are calculated by
M(x, y) = (
,
)
(2, -1) = (
,
)
In comparing both sides,
2 = (1 + x2)/2 and -1 = (6 + y2)/2
On simplifying,
2 = (1 + x2)/2
⇒ 4 = (1 + x2)
⇒ 1 + x2 = 4
⇒ x2 = 4 - 1
∴ x2 = 3
-1 = (6 + y2)/2
⇒ 6 + y2 = -2
⇒ y2 = -2 - 6
∴ y2 = -8
Thus, the coordinates of the required point are B(3, -8).
