Answer:

102 degrees.

Step-by-step explanation:

Because the 3.3's are congruent (the same), this triangle is isosceles.

A property of isosceles means that the two angles are congruent.

39+39= 78

This means that the last angle must be 180-78.

What is the area of a circle with a diameter of 15.8 cm? Use 3.14 for pi and round your final answer to the nearest hundredth. E
wariber [46]

Answer:

A=195.97 cm^2

Step-by-step explanation:

Area of a circle is given by

A = pi r^2

We are given the diameter.  We need to find the radius

d= 2r

15.8 = 2r

Divide by 2

7.9 =r

Now we can find the area

A = pi * (7.9)^2

A = pi *62.41

Let pi = 3.14

A = (3.14) * 62.41

   = 195.9674 cm^2

We round to the nearest hundredths

A=195.97 cm^2

If a person is born every 5 seconds and a person dies every 12 seconds, then how many seconds does it take for the population to
harina [27]

Solution:

As per the problem

A person is born every 5 seconds and a person dies every 12 seconds.

Here the LCD of 5 and 12 is 60.

The number of person born in 60 seconds=\frac{60}{5}=12\\

The Number of person died in 12 seconds=\frac{60}{12}=5

Hence Population increase in 60 seconds is=12-5=7\\

Hence time required to increase the population by one =\frac{60}{7} \ \ seconds\\
