If the whole angle (ABC) is equal to 133, we can add angles ABD and DBC to find x.

10x+13=133
Subtract 13 from both sides to get
10x=120
Divide both sides by 10 to get that x=12

We can now plug the value of x into ABD to find its measure.
7(12)+4
Simplifies to 84+4, which is 88

So angle ABD is equal to 88 degrees.

The population of a county is growing at a rate of 9% per year, compounded continuously. How many years will it take for the pop
torisob [31]

Answer:

t=15.4\ years

Step-by-step explanation:

The  exponential growth function compounded continuously is equal to

A=P(e)^{rt}  

where  

A is the final population  

P is the initial population  

r is the rate of growth in decimal  

t is Number of years

e is the mathematical constant number

we have  

A=4x\\P=x\\ r=9\%=9/100=0.09  

substitute in the function above

4x=x(e)^{0.09t}    

simplify

4=(e)^{0.09t}

Take natural log of both sides

ln(4)=ln[(e)^{0.09t}]

ln(4)=0.09t(ln(e))

ln(e)=1

ln(4)=0.09t

t=ln(4)/0.09

t=15.4\ years

Find the area of the regular hexagon PQRSTU of sides 8 cm as shown in the figure
Lemur [1.5K]

Answer:

Area = 245m^2

Step-by-step explanation:

We can split this figure into 2 parts, a rectangle and a trapezoid.

Rectangle Sides = 10m and 20m

Area = 10m x 20m = 200m

Trapezoid formula = a+b/2(h)

a and b are the 2 bases and h is the height

Using a little deductive reasoning we get the following, 5+10/2(6)

This simplifies to 15/2(6) -->

7.5(6) = 45

Thus, our area is 200 + 45, or 245m^2
