Name non equivalent fractions

1 answer:

7 0

Nonequivalent fractions are not equal to each other. To determine if two fractions are nonequivalent, you must also cross multiply. For example, to determine if 1/3 and 2/5 are equivalent, you must multiply 1 times 5, which equals 5, and 3 times 2, which equals 6.

You have a total of $3.25 in change made up of 25 pennies, 6 nickels, 2 dimes, and x quarters. How many quarters do you have?

coldgirl [10]

Answer:

10 quarters

x=10

Step-by-step explanation:

25 pennies equals to .25 ⊄

6 nickels equals to .30⊄

2 dimes equals to .20⊄

Add it up: 25+30+20=75⊄

You will then subtract .75 from our total:

3.25-.75=2.50

You need 2.50 in quarters; remember .50 for two quarters and 1.00 for four.

Eight quarters will equal 2.00

and two quarters equals 50.

Add it up, 10 for 2.50.

You will have 10 quarters.

X=10

Compute i^1+i^2+i^3....i^99+i^100

fgiga [73]

Good morning ☕️

Answer:

Step-by-step explanation:

Consider the sum S = i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰

S = i¹ + i² + i³ + . . . + i⁹⁹ + i¹⁰⁰

S = a₁ + a₂ + a₃ +. . . + a₉₉ + a₁₀₀

then, S is the sum of 100 consecutive terms of a geometric sequence (an)

where the first term a1 = i¹ = i and the common ratio = i

FORMULA:______________________

$S=(term1)*\frac{1-(common.ratio)^{number.of.terms}}{1-(common.ratio)}$

_______________________________

then

$S=i*\frac{1-i^{100} }{1-i}$

or i¹⁰⁰ = (i⁴)²⁵ = 1²⁵ = 1 (we know that i⁴ = 1)

Hence

S = 0
