What is the measure of the missing angle in the triangle I ready

Westkost [7]

I don't know how to answer this because i don't know the other numbers. But I can tell you to find a missing angle all the angles must add up to 180. So just add the other numbers and subtract the answer from 180 then you should get an answer.

Evaluate 105*95 using identities

Nikolay [14]

Answer:

9975

Step-by-step explanation:

See attachment.

( 105 ) * ( 95 )

(100+5) * (100-5)

100*100 * (1 + 5/100) * ( 1 - 5/100)

10000 * ( 1 - 5/100 + 5/100 - {25/10000} )

- 5/100 + 5/100, they cancel each other out to 0

10000 * ( 1 + 0 - {25/10000} )

10000 * ( 1 - {25/10000} )

10000 - {25*10000/10000}

10000 - {25}

pochemuha

Answer:

2 Hours

Step-by-step explanation:

Required man hours to complete the full job = 12 *15

=180 Man hours

Required man hours to complete the 2/5 of the job = 180/5

= 36 Man hours

if 18 peoples are working,

required hours to complete the 2/5 of the job = 36 /18

= 2 hours

The surface area of a sphere is 113.04 mm2. What is the volume of the sphere? Use 3.14 for π and round to the nearest hundredth.

Phoenix [80]

By definition, the surface area of the sphere is given by:
$A = (4) * ( \pi ) * (r ^ 2)
$
Where,
r: sphere radio
Clearing r we have:
$r = \sqrt{A / (4 * \pi )} 

$
Substituting values:
$r = \sqrt{113.04 / (4 * 3.14 )}$
$r = 3 mm
$
Then, the volume of the sphere is given by:
$V = (4/3) * (\pi) * (r ^ 3)
$
Substituting values we have:
$V = (4/3) * (3.14) * (3 ^ 3)

 V = 113.04 mm ^ 3$
Answer:
the volume of the sphere is:
$V = 113.04 mm ^ 3$
