Answer:
Thermal/Heat energy, kinetic energy, light energy, & Electromagnetic energy
I didn't have a dollar bill handy. So I conducted an extensive, exhaustive, in-depth, 2-minute internet search to determine the length of one. (I lived in Boston for 6 years and it had a profound effect on me. All during the 2 minutes of my research, I kept mumbling "dorla bill" to myself.) Anyway, the length of a US dorla bill is 6.14 inches.
We want to find out HOW MANY dorla bills it would take. We don't know that number yet, but we need to use it in our math, so we have to use something to put in its place until we find out the actual number. Most people would use 'x'. I'm going to use ' M '.
Length of 1 bill . . . . . 6.14 inches
Length of ' M ' bills . . . . . (6.14 M) inches
Circumference of the Earth at the equator . . . . . 40,075 km
inches in 1 foot . . . . . 12
feet in 1 meter . . . . . 3.28084
meters in 1 km . . . . . 1,000
This is all the outside information we need. The rest is all arithmetic.
==========================================
length of 1 bill, in inches . . . . . 6.14 inches
length of ' M ' bills, in inches . . . . . (6.14 M inches)
length of ' M ' bills, in feet . . . . .(6.14 M inches) x (1 foot/12 inches)
length of ' M ' bills, in meters . . . . .
(6.14 M inches) x (1 foot/12 inches) x (1 meter/3.28084 foots)
length of ' M ' bills, in km . . . . . (6.14 M inches) x(1 foot/12 inches) x(1 meter/3.28084 foots) x(1 km/1,000 m)
. . . . . . . . . . ^ these numbers are equal \/ . . . . . . . . . .
Circumference of the equator . . . . . 40,075 km
==============================================
Gather all the numbers together, and all the units together:
(6.14M x 1 x 1 x 1)/(12 x 3.28084 x 1,000) x (inch-foot-meter-km/inch-foot-meter) = 40,075 km
Do the arithmetic, and cancel out units that appear on both top and bottom:
(0.000155956 M) x (km) = 40,075 km
Divide each side by 0.000155956 km, and you'll have:
M = (40,075 / 0.000155956)
M = 256.96 million bills
============================================
Quick check, just to see if it makes sense:
Round each dorla bill to 6 inches even:
(256.96 million x 6 inches) x (1 ft/12 inch) x (1 mile/5280 ft) = 24,333 miles
Well, the same internet says the equator's circumference is 24,901 miles. YAY ! ! ! As an engineer, I'd say the two numbers match perfectly. So the answer to the question is confirmed to be
256.96 million bills
(2.57 x 10⁸ bills)
Answer:
The one in the middle
Explanation: i listened to the other person and i got it wrong, this is the answer for edge2020 sience review on energy!!!!
trust me its the middle one!!!!!
And everyone if ur not sure, like 100% sure about an answer dont answer at all cuz for 1: ur taking up a spot for others to answer. for 2: you could make people wrong. And for 3: its annoying. And 4: it makes stuff like this happen!
<u>NOT ARGUEING IM JUST PUTTING MY THOUGHTS AND OPINIONS OUT THERE ;)</u><em> many thanks.</em>
Answer:
groups
Explanation:
vertical sections are called groups
Answer:
b. (4677)
Explanation:
You can apply the same equation we use to calculate the compound interest but with phones.
Look:
M = C.(1+i)^n
M = the total amount after 5 years
C = the firts amout of phones (285)
i = how much this number gets bigger (75%)
n = the number of periods (5 years)
So...
M = 285 . (1 + 0,75)^5
M = 285 . 1,75^5
M = 285 . 16.4
M = 4677
