The area of the parallelogram is 391 cm².
The area of a parallelogram is calculated by multiplying the base by the height.
A=b×h
A=23 cm×17 cm
A=391 cm²
Rational numbers can be defined as numbers that can be written in fractional notation. Let's consider an arbitrary number
, where a and b do not have common factors. This is an example of a rational number, as it can be described using a fraction. Real numbers and fractional numbers are among this branch of numbers.
Irrational numbers, on the other hand, are simply those numbers which cannot be written as an exact fraction, only approximated fractions. Famous cases of irrational numbers are those of π (pi), e (Euler's number/ Napier's constant), and many square root numbers.
Given:
1st map = 8 cm
2nd map = 6 cm
1 cm in the map is equal to 2 km on the actual trail.
8 cm * 2km/1cm = 16 km is the actual length of the trail in the first map
6 cm * 2km/1cm = 12 km is the actual length of the trail in the second map.
I'm not sure on how to get the scale factor from the map to the actual trail. I'm confused if I had to consider cm and km because 1km is equal to 100,000 cm.
Proportion of the second map to the first map is 6/8
6/8 = x/3 → 6*3 = 8x → 18/8 = x → 2.25
6/8 = x/4 → 6*4 = 8x → 24/8 = x → 3
6/8 = x/5 → 6*5 = 8x → 30/8 = x →3.75
The side measure of the triangle in the second map is only 75% of the side measure of the triangle in the first map.
Answer:
<u>Final equation: y = -7x -19 </u>
Step-by-step explanation:
You are looking for slope intercept correct?
Formula: y = mx + B
Y = y-value of point ( coordinates )
M = slope
X = x - value of point ( coordinates )
B = Y - intercept
Equation:
2 = -7(-3) + B
2 = 21 + B
-21 = -21 = B
------------------
-19 = B
Final equation: y = -7x -19
Unless if it asks you to plug back the numbers for anything else then you do that but this is how you get slope intercept.
2(a - 3) + 2(4a - 10) =
= 2a - 6 + 8a - 20 =
= 2a + 8a - 6 - 20 = <u>1</u><u>0</u><u>a</u><u> </u><u>-</u><u> </u><u>2</u><u>6</u> ← the end
