( THE SUM OF THE MEASURES OF THE ANGLES BELOW IS 180* ) I will give brainlst for whoever gets this right and fills it out
Rufina [12.5K]

Answer:

2x-10+x+x+10=180, or 4x=180

Step-by-step explanation:

So since the total is 180, you add them all up like an equation.

So,

2x-10+x+x+10

Combine like terms

4x=180

x=45

Then plug it back in to the equations.

x=45

(2x-10)=80

(x+10)=55

Find the volume of a cone with a diameter of 7 inches and a height that is 4 times the radius. Use 3.14 for pi, and round your a
Tatiana [17]

Answer:

179.50 in^{3}

Step-by-step explanation:

The equation for volume of a cone is:

V=\pi *r^{2} *\frac{h}{3}

The radius is half of the diameter so r= 3.5 in

The height is 4 times the radius so h=14

V=3.14*3.5^{2} * \frac{14}{3}

V= 179.50 in^{3}

Help please!!!!!!!!!!!!!!
marshall27 [118]

Step-by-step explanation:

as in the other problem, the table describes mutually exclusive attributes.

so, we can simply sum the numbers up to get the total number of students :

3+9+2+16 = 30 students.

so, when picking a random student, we have 30 possibilities.

now, how many of those 30 have the desired attributes (to have a brother AND a sister) ?

I see 3 in the table.

so, the probability to pick a student that has a brother and a sister is

3/30 = 1/10 = 0.1
