ryan has $0.75 worth of pennies and nickels. He has 3 more nickels than pinniped. Determine the number of pennies and the number of nickels that ryan has

Answers

Answer:

Ryan has 10 pennies and 13 nickels.

Step-by-step explanation:

Let the number of pennies be p and the number of nickels be n.

We have two unknowns, the number of pennies and the number of nickels, so we need two equations. One equation will deal with the value of the coins. The other equation will deal with the number of coins.

Value of coins:

1 penny is worth $0.01; p pennies are worth 0.01p.

1 nickel is worth $0.05; n nickels are worth 0.05n.

The total amount the coins are worth is

0.01p + 0.05n

The coins are worth $0.75, so we have our first equation.

0.01p + 0.05n = 0.75       Equation 1

Number of coins:

He has p pennies.

The number of nickels is 3 more than the number of pennies.

Since the number of pennies is p, then the number of nickels is p + 3.

That gives us our second equation.

n = p + 3        Equation 2

System of equations:

Now we have a system of two equations in two unknowns:

0.01p + 0.05n = 0.75

n = p + 3

Since the second equation is already solved for n, we can use the substitution method.

Replace n in the first equation with p + 3.

0.01p + 0.05n = 0.75

0.01p + 0.05(p + 3) = 0.75

Distribute the 0.05

0.01p + 0.05p + 0.15 = 0.75

Combine like terms on the left side.

0.06p + 0.15 = 0.75

Subtract 0.15 from both sides.

0.06p = 0.6

Divide both sides by 0.06.

p = 0.6/0.06

p = 10

Now we substitute 10 for p in the second equation to find the value of n.

n = p + 3

n = 10 + 3

n = 13

He has 10 pennies and 13 nickels.

Check:

A) 13 - 10 = 3 He does have 3 more nickels than pennies.

B) $0.01(10) + $0.05(13) = $0.10 + $0.65 = $0.75

The number of coins and the value of the coins both check out, so our answer is correct.

Answer: Ryan has 10 pennies and 13 nickels.

If the mFT 3x - 2 and the mFE = 5x + 1, Find x and mTE. (GT is median)
Please get back to me soon, I'll give Brainliest!​

Answers

Answer:

x = 5

TE = 13

Step-by-step explanation:

Since GT is the median, then 2*(FT) = FE.

FE = 5x + 1

FT = 3x - 2

Therefore:

2*(3x - 2) = 5x + 1 (substitution)

6x - 4 = 5x + 1

Collect like terms

6x - 5x = 4 + 1

x = 5

TE = ½*(FE)

TE = ½*(5x + 1)

Plug in the value of x

TE = ½*(5(5) + 1)

TE = ½(25 + 1) = ½(26)

TE = 13

A bacteria triples its original population in 25 hours (A=3A0). How big will its population be in 100 hours?

Answers

Answer:

81 times the original size.

Step-by-step explanation:

AA0ktA=3A0=?=?=25hours=A0ekt

Substitute the values in the formula.

3A0=A0ek⋅25

Solve for k. Divide each side by A0.

3A0A0=e25k

Take the natural log of each side.

ln3=lne25k

Use the power property.

ln3=25klne

Simplify.

ln3=25k

Divide each side by 25.

ln325=k

Approximate the answer.

k≈0.044

We use this rate of growth to predict the number of bacteria there will be in 100 hours.

AA0ktA=3A0=?=ln325=100hours=A0ekt

Substitute in the values.

A=A0eln325⋅100

Evaluate.

A=81A0

At this rate of growth, we can expect the population to be 81 times as large as the original population.

81
