Answer:

For only the rectangle (that I've coloured in with red) I assume it would be 9 inches squared. However, when adding on the triangles on the side, it would be 9+3+3 = 15

Amy had 23 blocks she gave 7 blocks to isabela and 5 blocks to alexa here are the choices A. (23-7)+5 and B.23-(7+5) and C. 23-7
Semmy [17]

Answer:

C seems right

Step-by-step

seems more work then needs be but 7+5= 12 and she originally had 23. so the equation of adding the 7+5 would just be adding up the ones removed together then adding the -23 to the equation is how many Amy had to begin with. so it would be <u><em>23-7+5 </em></u>= 12. others dont seem right since when you add () to an equation that means your multiplying and you wouldn't be multiplying here and for D to be right it needs to be switched around or you'd end up with a - number and she wouldn't have a - number of blocks. just divide up a problem if need be and break it down to smaller parts to make it easier to deal with.

How long will it take for $2500 to double if it is invested at 6% annual interest compounded 6 times a year? Enter exact calcula
12345 [234]

Answer:

Part 1) t=11.610\ years

Part 2) t=11.552\ years

Step-by-step explanation:

Part 1) we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

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  

n is the number of times interest is compounded per year

in this problem we have  

A=\$5,000\\P=\$2,500\\ r=6\%=6/100=0.06\\n=6  

substitute in the formula above

5,000=2,500(1+\frac{0.06}{6})^{6t}  

2=(1.01)^{6t}  

Apply log both sides

log(2)=log[(1.01)^{6t}]

log(2)=(6t)log(1.01)  

solve for t

t=log(2)/[6log(1.01)]  

t=11.610\ years

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

we have  

A=\$5,000\\P=\$2,500\\ r=6\%=6/100=0.06  

substitute in the formula above

5,000=2,500(e)^{0.06t}

2=(e)^{0.06t}  

Apply ln both sides

ln(2)=ln[(e)^{0.06t}]

ln(2)=(0.06t)ln(e)

ln(2)=(0.06t)

t=ln(2)/(0.06)

t=11.552\ years
