The variable “x” is 129 degrees.

Olin [163]3 years ago

6 0

Answer:

129

Step-by-step explanation:

All the angles have to add up to 360.

1 line equals 180

180-51= 129

-- the angle opposite 51 also equals 51

-- x = 129

- so the angle opposite the x (129) equals 129 as well

Find the approximate surface-area-to-volume ratio of a bowling ball with a radius of 5 inches.

Nataly_w [17]

Surface area of a ball:
S=4πr^2=4*π*5^2=100π

Volume of a circle:
V=4/3*π*r^3=4/3*π*125=(500/3)*π=165π

The approximate surface-area-to-volume ratio would be 1:1,5

The edge length of cube A is two times the edge length of cube B. How many times greater isthe volume of the cube A than the vol

allsm [11]

Answer:

<h2>8 times greater</h2>

Step-by-step explanation:

The formula of a volume of a cube:

$V=a^3$

a - edge length

-----------------------------------

The edge length of cube B is a.

The edge length of cube A is 2a.

Calculate the volumes:

$V_A=(2a)^3=2^3a^3=8a^3\\\\V_B=a^3$

How many times greater is the volume of the cube A than the volume of cube B?

Make the quotient:

$\dfrac{V_A}{V_B}=\dfrac{8a^3}{a^3}=8$

What is the distance from the point (−3, −b, c) to the origin?

lord [1]

Answer:

$\sqrt{9+b^2+c^2}\,\text{units}$

Step-by-step explanation:

The distance formula tells you the distance d between the points (0, 0, 0) and (-3, -b, c) is ...

d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²) = √((-3-0)² +(-b-0)² +(c-0)²)

= √(9 +b² +c²)
