Hector solves this equation:

disa [49]

Answer:

9x+8=23 HOPE THIS HELPS

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

17+7x−9=19−2x+4

17+7x+−9=19+−2x+4

(7x)+(17+−9)=(−2x)+(19+4)(Combine Like Terms)

7x+8=−2x+23

7x+8=−2x+23

Step 2: Add 2x to both sides.

7x+8+2x=−2x+23+2x

9x+8=23

Step 3: Subtract 8 from both sides.

9x+8−8=23−8

9x=15

Step 4: Divide both sides by 9.

9x /9 = 15 /9

x= 5 /3

ahrayia [7]

Answer:

129.3 feets

Step-by-step explanation:

Using the solution diagram attached below :

The difference in height of the two buildings :

Building B - Building A = (654 - 480) = 174 feets

Using trigonometry :

Cosθ = opposite / Adjacent

Cos 42 = d / 174

d = 174 * Cos 42

d = 129.307

d = 129.3 feets

An egg of a particular bird is very nearly spherical. The radius to the inside of the shell is 4 millimeters and the radius to t

igomit [66]

Answer: The volume of shell is 12.8π mm².

Step-by-step explanation:

Since we have given that

Radius to the inside of the shell = 4 milimeters

Radius to the outside of the shell = 4.2 milimeters

Since r changes from 4 mm to 4.2 mm

so, $dr=4.2-4=0.2\ mm$

As we know that

Volume of shell is given by

$\dfrac{4}{3}\pi r^3$

$dv=\dfrac{4}{3}\pi 3r^2\ dr\\\\dv=4r^2\pi\ dr\\\\dv=4(16)\times 0.2\pi\\\\dv=12.8\pi$

So, the volume of shell is 12.8π mm².
