Answer:

x=68 and y = 112

Step-by-step explanation:

angles of a triangle must equal 180, so

52°+60°+x°=180

112+x=180 <-- subtract 112 to get x on one side.

x=68

To solve for y, a straight line = 180 so

68+y=180 --> just subtract 180-68

y=112

A sum of money is invested at 12% compounded quarterly. About how long will it take for the amount of money to double?

kompoz [17]

Answer:

5.9 years

Step-by-step explanation:

We believe a better representation of the compound interest formula is ...

$V(t)=P(1+\dfrac{r}{n})^{nt}$

We want to find the value of t for P=1 and V(t)=2. We are told n=4, so the formula becomes ...

$2=(1+\dfrac{.12}{4})^{4t}\\\\\log{(2)}=4t\log{(1.03)}\quad\text{take logs}\\\\t=\dfrac{\log{2}}{4\log{1.03}}\approx\boxed{5.9\quad\text{years}}$

What is the product of 2.52 and 3.4

ElenaW [278]

2.52 x 3.4

= (2.50 + 0.02)(3.00 + 0.40)

= 2.50 x 3.00 + 2.50 x 0.40 + 0.02 x 3.00 + 0.02 x 0.40

= 7.500 + 1.000 + 0.060 + 0.008

= 8.500 + 0.060 + 0.008

= 8.560 + 0.008

= 8.568
