Answer:

i think it is 20 + 5x = 50    or  f(x)=2(3^x)

Step-by-step explanation:

equation to show how many cakes sam baked this week:

20 + 5x = 50

20 = 20 dollars

5 = 5 more dollars

x = number of cakes

therefore, sam earned $50 this week.

Answer:

20+5x=50

x will represent the number of cakes she baked

she gets paid $5 for every cake she bakes, this is where the 5x comes from

she makes $20 ("in addition" that's where the "+20" comes from) a week. However, in this case we're only talking about what she made in one week, hense why there is no variable attached to the 20

she makes a total of $50

20+5=50

she baked a total of 6 cakes. How?

subtract 20 from both sides so you have:

5x=30

divide both sides by 5 to get x by itself:

x=6

Ms. LaTrace teaches her 27 students to make folded-paper princesses. Each student can make about 2 princesses in 1 minute. ABOUT
saveliy_v [14]

Answer:

About 2970 princesses

Step-by-step explanation:

This is calculated as:

For 1 student:

1 minute = 2 princesses

55 minutes = x princesses

x = 55 × 2 princesses

x = 110 princesses.

Hence: 1 student can make 110 princesses in 55 minutes.

The amount of princesses all the students make in 55 minutes is calculated as:

1 student = 110 princesses

27 students = x

x = 27 × 110 princesses

x = 2970 princesses

The amount of princesses all the students make in 55 minutes is about 2970 princesses.

4How much money will Jack have after 7 years if he invests $5,000at 3% interest compounded continuously?
erik [133]

Answer:

$6168.39

Explanation:

For a principal, P compounded continuously at a rate of r%, the amount in the account after t years is determined using the formula:

A(t)=Pe^{rt}

Given:

• The starting amount, P = $5,000

,

• Interest Rate, r = 3% = 0.03

,

• Time(t) = 7 years

Substitute these values into the formula:

\begin{gathered} A(7)=5000\times e^{0.03\times7} \\ =\$6168.39 \end{gathered}

Jack will have $6168.39 in his account after 7 years.

goldenfox [79]
This is the answer:

(3m^-2 n)^-3 / 6mn^-2
1st step: distribution of power3^-3 m^-2*-3 n^-3 / 6mn^-2
2nd step: use product and quotient rulem^6 n^2/ 3^3 *6*m*n^3
3rd and last step: simply expressionm^5/162n
The answer is m^5/162n

Hope this helps. :)
