Answer:

125˚

Step-by-step explanation:

The angles given are supplementary. So we can set up the equation :

(3x+5)+(x+15)=180

Then we can solve for x.

Combine like terms:

4x+20=180

4x+20-20=180-20

4x=160

4x/4=160/4

x=40

Now we plug in 40 for x.

3(40)+5=<A

120+5=<A

<A=125

The population of a small town is decreasing at a rate of 7% per year. If the town's population is 13,250 now, what will be the

Diano4ka-milaya [45]

Answer:

The approximate population of the small town after 10 years is 6,413

Step-by-step explanation:

Here we note that the general growth formula is given by;

$A = P(1+r)^{t}$

For decreasing rate, we have;

$A = P(1-r)^{t}$

Where:

A = Population after growth

P = Initial population = 13250

r = The annual reduction rate in decimals = 7 % = 7/100 = 0.07

t = Number of years of decrease= 10 years

Since the population is decreasing, then by plugging in our values into the above equation for decreasing rate, we have

$A = 13250(1-0.07)^{10}$

= 6.412.766 ≈ 6,413

The approximate population of the small town after 10 years = 6,413

Answer:

Step-by-step explanation:

10+10=20

8+8 = 16

36 is perimeter of the rectangle

diameter of half circle is 8

formula for circumference of a circle is r π = 8 x 3.14

8 x 3.14 = 25.12 but your not done yet its a half circle so divide by 2

25.12/2 = 12.56

12.56 + 36 = 48.56 is final answer

0.3d-1/3 1/3=.84:7/15

telo118 [61]

Answer:

$d=\frac{147}{6.3}$

Step-by-step explanation:

The right side is a ratio $0.84:\frac{7}{15}$
a ratio can be written as a fraction $\frac{0.84}{\frac{7}{15} }$ this means $0.84$ divide by $\frac{7}{15}$ which is the same as $0.84*\frac{15}{7}=\frac{12.6}{7}$
On the left, change the mixed fraction $3\frac{1}{3}$ to the improper fraction $\frac{10}{3}$
Then divide $0.3d-1$ by $\frac{10}{3}$ which is same as $(0.3d-1)*\frac{3}{10} =\frac{3(0.3d-1)}{10}$
So the equation is now $\frac{3(0.3d-1)}{10}=\frac{12.6}{7}$
Now multiply both sides by 10 and 7:
$(10)*(7)*\frac{3(0.3d-1)}{10}=\frac{12.6}{7}*(7)*(10)\\7*3(0.3d-1)=12.6*(10)\\21*(0.3d-1)=126\\6.3d-21=126\\6.3d-21+(21)=126+(21)\\6.3d=147\\d=\frac{147}{6.3}$
