Answer:
Given:
Two trail maps:
Trail on the first map = 8 cm
Trail on the second map = 6 cm
Scale on first map = 1 cm : 2 km
A) What is the scale factor from the map to the actual trail?
For the first map, the scale factor is 1 cm: 2km. Therefore the actual trail is 8 centimeters * 2 kilometers = 16 km.
The scale factor of the second map is 16 km / 6 cm = 2.67 km : 1 cm
B) The length of the actual trail is 16 kilometers.
Step-by-step explanation:
The answer is <span>amplitude = 2 feet; period = 24 hours; midline: y = 3
x1 - the lowest point
x2 - the highest point
x1 = 1 ft
x2 = 5 ft
t1 = 0
t2 = 24
The amplitude is: (x2 - x1)/2 = (5 - 1)/2 = 4/2 = 2 ft
The period is: t2 - t1 = 24 - 0 = 24 h
The midline is: (x1 + x2)/2 = (5 + 1)/2 = 6/2 = 3 ft</span>
Answer:
94
Step-by-step explanation:
78+90+86=246
246+94=340
340/4=85
Fourteen is 28% of B) 50
Why, you ask? Let's see -
Let the unknown number be n, for 'number'.
Let's put the unknown n next to 28%
.28n% = 14
(Think, what times .28 equals 14? Look below to find out! ↓ )
Let's now do the opposite of the actual equation - divide the two known numbers by each other -
.28 ÷ 14 = 50
When in doubt, check your answer:
To check this, we would do the opposite - Multiplication
Multiply .28 by 50 to get 14 (At least you should get 14)
.28 × 50 DOES EQUAL 14! We were right! :D
