Answers

Answer:

4090 ml - 4.9L

1.4km - 4901m

Step-by-step explanation:

A liter is made up of 1000 ml so 4.9 l is equvilant to 4,900 ml.

A kilometre same as litre is made up of a 1000 m. So 1.4 km is 1400m

However, ml and l is a measurement of volume while m and km is a measurement of distance.

Please hep me i will mark as the best please....

Answers

Answer:

A) $2,344.53

B) $2,340.36

C) Based on my answer in A and B, the Option i would choose is Option A. This is because the amount i would receive after 2 years in Option A is higher than that of Option B

Step-by-step explanation:

We solve for A and B using Compound Interest formula

A). You plan to invest $1978 in an account with two different options. Option 1 earns 8.5% annually, with interest to be compounded continuously. How much money would you have in the account after 2 years?

First, convert R as a percent to r as a decimal

r = R/100

r = 8.5/100

r = 0.085 rate per year,

Then solve the equation for A

The formula is given as

A = Pe^rt

A = 1,978.00(2.71828)(0.085)(2)

A = $2,344.53

B). You plan to invest $1978 in an account with two different options. Option 2 earns 8.5% annually, with interest to be compounded quarterly. How much money would you have in the account after 2 years?

First, convert R as a percent to r as a decimal

r = R/100

r = 8.5/100

r = 0.085 rate per year,

Then solve the equation for A

The formula is given as

A = P(1 + r/n)^nt

P = Principal = $1978

r = 0.085

n = compounded quarterly = 4

A = 1,978.00(1 + 0.085/4)(4)(2)

A = 1,978.00(1 + 0.02125)(8)

A = $2,340.36

C). You plan to invest $1978 in an account with two different options. Based on your two previous answers, which option would you choose and why?

Based on my answer in A and B, the Option i would choose is Option A. This is because the amount i would receive after 2 years in Option A is higher than that of Option B

You start at (2, 3). You move up 6 units. Where do you end?

Answers

Answer:

(2,9)

Step-by-step explanation:

we start at the point (2,3) and moving up 6 units

when we move up or down, we are changing the value of the y-coordinate. Since we are moving up, the value of the y-coordinate increases (makes sense, if you are thinking about a graph. The further you go up, the larger the y value becomes).  

However, the x-coordinate will stay the same (no instructions on moving left or right {that changes the x value}). That means the y value will increase by 6 while the x value will stay the same.

so add 6 to 3 and get 9, and add nothing to 2

therefore, the point we end on will be (2,9)

$4 for 1/4 of a pie, means that it isn't an entire pie. Luckily for us, this is simple multiplication. You would multiply like so:

4 x 4 = 16

And you'd get your answer, since 4/4 equals 1 whole.

At Lincoln Middle School, 1/3 of the students play a musical instrument. Of the students who play instruments, 3/4 tried out for the class play. What is the probability that a student
selected at random plays a musical instrument and tried out for the class play?
25%
33%
66%
75%

Answers

it is 25% ...................

The probability that a student selected at random plays a musical instrument and tried out for the class play is 25%.

To find the probability that a student selected at random plays a musical instrument and tried out for the class play, we need to multiply the probabilities of each event happening.

Given:

Probability of a student playing a musical instrument = 1/3

Probability of a student who plays an instrument trying out for the class play = 3/4

To find the combined probability, we multiply these probabilities:

Probability = (1/3) * (3/4)

Simplifying the multiplication:

Probability = 1/4

Converting the fraction to a percentage:

Probability = 1/4 * 100% = 25%

Therefore, the probability that a student selected at random plays a musical instrument and tried out for the class play is 25%.
