M = Tim's dollar amount
R = Rebecca's dollar amount
MR = Tim and Rebecca's dollars together

R = (M x 1/10) - 6

MR = M + ((M x 1/10) - 6)

MR = 70 + ((70 x 1/10) - 6)

MR = 70 + (7 - 6)

MR = 70 + 1

MR = 71

Answer:

Total amount both have together = $71

Step-by-step explanation:

Tim has the dollars = M

Rebecca is having = \frac{M}{10}-6 dollars

Total amount of money Tim and Rebecca are having = M + M/10 - 6

= (11M/10) - 6 dollars

Therefore the expression representing total amount of money = [(11x/10) - 6]

If Tim is having $70 then total amount both have together = [(11×70/10) - 6]

= (77 - 6) = $71

Therefore the expression for total amount is = [(11M/10)-6] dollars and

Total amount both are having together = $71

Answer:

Part 1) r=3.5\%  

Part 2) t=6\ years

Part 3) 21.9\ ft

Step-by-step explanation:

Part 1) we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

Let

x -----> amount of money to be invested

2x ---> Final Investment Value

we have  

t=20\ years\\ P=\$x\\A=\$2x\\r=?  

substitute in the formula above  

2x=x(e)^{20r}  

2=(e)^{20r}  

Apply ln both sides

ln(2)=ln[(e)^{20r}]  

ln(2)=(20r)ln(e)  

ln(2)=(20r)  

0.693=(20r)  

r=0.693/20  

r=0.035  

r=3.5\%  

Part 2) we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

Let

x -----> amount of money to be invested

2x ---> Final Investment Value

we have  

t=?\ years\\ P=\$x\\A=\$2x\\r=0.126  

substitute in the formula above  

2x=x(e)^{0.126t}  

2=(e)^{0.126t}  

Apply ln both sides

ln(2)=ln[(e)^{0.126t}]  

ln(2)=(0.126t)ln(e)  

ln(2)=(0.126t)  

0.693=(0.126t)  

t=0.693/0.126  

t=5.5=6\ years

Part 3) we have

f(x)=18.4+2.5ln(x+1)

where

f(x) -----> is the long jump record in feet

x -----> the number of years since the school was opened

so

For x=3 years

substitute

f(3)=18.4+2.5ln(3+1)

f(3)=18.4+2.5ln(4)

f(3)=18.4+2.5(1.386)

f(3)=21.9\ ft

A peach pie is made with 13 peaches, which are evenly distributed throughout the pie. If Joe ate one slice of pie that contained
pentagon [3]

Answer:

138.5°

Step-by-step explanation:

A peach pie is in the form of a circle. The sum of angles in a pie is equal to 360°.

Since there are 13 peaches evenly distributed, therefore each peach occupies 360/13 degrees.

Joe ate one slice of pie that contained exactly 5 peaches, hence:

Angle measure of slice = (number of peaches in the slice / total number of peaches) * 360°

Angle measure of slice = (5 / 13) * 360°

Angle measure of slice = 138.5°

Pavel [41]

Answer:

Polly can choose 33264 schedules.

Step-by-step explanation:

None of these sections interfere with each other, so:

For each statistics choice, there are 12 composition choices.

For each composition choice, there are 11 section of Ethics choices.

For each section of Ethics choice, there are 18 Physics choises.

There are 14 statistics choices.

From how many possible schedules can Polly choose?

14*12*11*18 = 33264

Polly can choose 33264 schedules.
