Answer:
a) 200 mm^2
b) 500 mm^2
c) 3.75e + 8
d) 6390 cm^2
e) 650 cm^2
f) 20 m/s
Step-by-step explanation:
For a) and b): 1 cm = 10 mm, multiply 20 (and 50) by 10
For c): the formula is to multiply 1e + 8
For d): 1 Liter = 1000 Cubic Centimeters (hopefully that's what you're referring to)
For e): 10 mm = 1 cm, divide by 10
For f): divide the value by 3.6
Answer:
the answer is 11.625 so it is <u><em>12</em></u>
Step-by-step explanation:
The given quadrilateral ABCD is a parallelogram since the opposite sides are of same length AB and DC is 4 and AD and BC is 2.
<u>Step-by-step explanation</u>:
ABCD is a quadrilateral with their opposite sides are congruent (equal).
The both pairs of opposite sides are given as AB = 3 + x
, DC = 4x
, AD = y + 1
, BC = 2y.
- AB and DC are opposite sides and have same measure of length.
- AD and BC are opposite sides and have same measure of length.
<u>To find the length of AB and DC :</u>
AB = DC
3 + x = 4x
Keep x terms on one side and constant on other side.
3 = 4x - x
3 = 3x
x = 1
Substiute x=1 in AB and DC,
AB = 3+1 = 4
DC = 4(1) = 4
<u>To find the length of AD and BC :</u>
AD = BC
y + 1 = 2y
Keep y terms on one side and constant on other side.
2y-y = 1
y = 1
Substiute y=1 in AD and BC,
AD = 1+1 = 2
BC = 2(1) = 2
Therefore, the opposite sides are of same length AB and DC is 4 and AD and BC is 2. The given quadrilateral ABCD is a parallelogram.
The answer is d because 4+8=12 and they are 4 units away from eachother:)
