Answer:

The summands are 4 and 5. The sum is 9.

Step-by-step explanation:

In the binary system, the digits, starting at the right and moving to the left are:

1's

2's

4's

8's

etc.

100 = 0 units + 0 2's + 1 four = 0 + 0 + 4 = 4

101 = 1 unit + 0 2's + 1 4's = 1 + 0 + 4 = 5

In decimal, the addition is:

4 + 5 = 9

The summands are 4 and 5. The sum is 9.

Answer:

∠1 - 40°

Step-by-step explanation:

∠1 - 40°

b/c it's a right triangle and we have two angles given, 50° and 90°. Add them and subtract by 180° and get 40°.

∠2 - 140°

b/c an exterior (outside) angle is equal to the two most isolated / farthest angles added. The two most is angles are 105° and 35°, add them and get 140°.

∠3 - 40°

b/c ∠'s 1 and 3 are vertical angles meaning they're equal so since ∠1 is 40°, so is ∠3.

∠4 -

b/c ∠' s 2 and 4 are vertical angles meaning they're equal so since ∠2 is 140°, so is ∠4.

∠5 - 35°

b/c we have two angles, 105° and 40°. Add them and subtract by 180° and get 35°.

~~

I hope that helps you out!!

A cylindrical metal pipe has a diameter of 8.4 millimeters and a height of 10 millimeters. A hole cut out of the center has a di
zhannawk [14.2K]

To solve this problem, we simply use the equation of volume for hollow cylinders:

V = π h (R^2 – r^2)

where V is volume, h is height = 10, R is outer radius = 8.4/2 = 4.2, r is inner radius = 6/2 = 3

 

V = π (10) (4.2^2 – 3^2)

Which value is a solution to the inequality 5x – 1 ≤ –11?
avanturin [10]

Answer:

x≤-2

Step-by-step explanation:

To solve the inequality, we have to add 1 on each side:

5x-1≤11

  +1   +1

And then we get:

5x≤-10.

To find x, we have to divide each side by 5:

5x/5≤-10/5

After we do that, we get:

x≤-2.
