log7 1= log1/log7= 0 (log1=0)

log5 625= log625/log5= log5^4/log5= 4log5/log5= 4 (log5=0.69)

What is 18w-2=10w+14?

NeTakaya

w = 2

BECAUSE

The first step is subtract both sides by 10w. Once you do that you are left with

8w - 2 =+ 14

Then you add both sides by 2, leaving you with

8w = 16

Then you divide by 8, and you get your answer:

w = 2

100 points if you can answer this

Answer:

x = 124°

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5 , then

sum = 180° × 3 = 540°

sum the given angles and equate to 540°

90° + 122° + 105° + 99° x = 540° , that is

416° + x = 540° ( subtract 416° from both sides )

x = 124°

A soup can has a height of 4 inches and a radius of 2.5 inches. What's the volume of soup in cubic inches that would fill one so

Alenkasestr [34]

Answer:

C. 78.5 in^3

Step-by-step explanation:

A soup can is in the shape of a cylinder. The volume of a cylinder can be found using the following formula:

$v=\pi r^2h$

We know that the height is 4 inches and the radius is 2.5 inches.

r= 2.5 in

h= 4 in

$v=\pi (2.5in)^2*4in$

Evaluate the exponent.

$(2.5 in)^2=2.5 in*2.5in=6.25 in^2$

$v=\pi *6.25 in^2*4 in$

Multiply 6.25 in^2 and 4 in.

$6.25 in^2*4 in=25 in^3$

$v=\pi*25 in^3$

Multiply pi and 25 in^3.

$v=78.5398163 in^3$

Round to the nearest tenth. The 3 in the hundredth place tells us to leave the 5 in the tenth place.

$v=78.5 in^3$

78.5 cubic inches can fill one soup can.
