Angle 1 = 4x - 16
angle 2 = 2x + 10

4x - 16 + 2x + 10 = 90
combine like terms

6x - 6 = 90
add 6 to both sides

6x = 96
divide both sides by 6

x = 16

angle 1 = 4x - 16 = 4(16) - 16 = 48

angle 2 = 2x + 10 = 2(16) + 10 = 42

Solve the equation for P: 3k=7Q+6p
iren [92.7K]

3k=7Q+6p

Solve for P which means we have to make 'p' alone

3k=7Q+6p\\\\ Add  7Q on both sides \\\\ 3k - 7Q = 7Q - 7Q + 6p\\\\ \left ( 3k - 7Q \right ) = 6p\\\\ Divide both side by 6 to make p alone \\\\ \frac{\left ( 3k - 7Q  \right )}{6} = \frac{6p}{6}\\\\ p = \frac{\left ( 3k - 7Q  \right )}{6}

The area of a cross section through the center of a sphere is 46 square inches. Find the surface area of the sphere.
gavmur [86]

Answer:

184 in.^2

Step-by-step explanation:

The cross section through the center of a sphere is a circle whose radius is equal to the radius of the sphere.

area of circle

A_{circle} = \pi r^2

\pi r^2 = 46

r^2 = \dfrac{46}{\pi}

r = \sqrt{\dfrac{46}{\pi}}

r = 3.83 ~in.

surface area of sphere

SA = 4 \pi r^2

SA = 4 \times \pi \times (3.83)^2

SA = 184~in.^2
