Answer:

  40

Step-by-step explanation:

Angles ABO, BAO, and AOB are the angles of isosceles triangle AOB. The angles at A and B are equal, so we have ...

  AOB +2ABO = 180° . . . . . sum of angles in the triangle

  100° +2ABO = 180° . . . . . . use the given value

  50° +ABO = 90°  . . . . . . . . divide by 2; next, subtract 50°

  ∠ABO = 40°

A computer is programmed to scan the digits of the counting numbers. For example, if it scans 1 2 3 4 5 6 7 8 9 10 11 12 13 then
Charra [1.4K]

I believed it is "401"

1-9 = 9 digits

10-99 = 90 which is 180

100-200 = 100 which is 300 digits

9+180= 189

1392-189= 1203

1200÷300=400 which 1200 digits

401 is the 1392 number scanned

600 feet of fence surround a rectangular playground that is 100 feet wide. How long is the playground? A.400 b.500 c.300 d.200
Paladinen [302]

Answer:

A.400

Step-by-step explanation:

Well perimeter for a rectangle is l+l+w+w

100+100+l+l=600

200+2l=600

<em>Subtract 200 from both sides</em>

2l=400

<em>Divide both sides by 2</em>

l = 400 feet

The length of the rectangle is 400 feet long.

A lighting designer is finalizing the lighting plan
kykrilka [37]

Answer:

No

Step-by-step explanation:

It depends on the shape of the stage, generally, the stage is cuboidal or cubical in shape, so assuming the stage is cuboidal.

Here, the spotlight has top cover the minimum angle of 90° (for a corner position of the spotlight.

Now, compute how much angles the spotlight can cover.

From its central position, the spotlight can rotate 25° to the left or right, so, angle covered due to rotation is 25°+25°=50°.

As the beam of light from the spotlight can spread 22°.

So, the total angle covered by spotlight= 50° + 22°=72°, which is less than the minimum angle required to cover the entire stage.

Hence, the designer can't use the spotlight to light each of the objects on the stage.
