Mathematics

Flauer [41]3 years ago
6 0

Answer:

∠B = 86°

Step-by-step explanation:

Given ∠A and ∠B are supplementary angles.

That is , ∠A + ∠B = 180°

            ( 6x + 10)° + ( 4x + 30)° = 180°

             6x + 10 + 4x + 30 = 180

                 10x + 40 = 180

                 10x = 180 - 40

                     10x = 140

                      x = 14

Therefore, ∠A = (6x + 10) ° = (( 6 x 14) + 10)° = 94°

                ∠ B = ( 4x + 30)° = (( 4 x 14) + 30)° = 86°

Twelve more than seven times a number is the number plus 18. What is the number?
dangina [55]

Answer:

1

Step-by-step explanation:

Let the number be X

condition

12 more than seven times the number

it can be represented numerically by using process given belwo

seven times the number will be 7 * X = 7X

12 more than 7X will be equal to 7X + 12

______________________________

This number (7X + 12) is equal to number plus 19

number plus 18 will be X + 18

therefore according to the question

7X + 12  = X + 18

=> 7X - X = 18 - 12

=> 6X = 6

=> X = 6/6 = 1 (Answer)

The number is 1.

Agent Bourne transferred classified files from the CIA mainframe into his flash drive. The drive had 3 6 . 5 36.536, point, 5 me
BaLLatris [955]
I'm not sure what the question is.

Given:
Flash drive capacity 1,000 megabytes
Initial content before transfer of files 36.5 megabytes

After 125 seconds, there were 549 megabytes on the drive.

549 - 36.5 = 512.5 megabytes is the weight of the transferred files.

512.50 megabytes / 125 seconds =  4.1 megabytes per second

The rate of transfer is 4.10 megabytes per second.

1000 - 549 = 451 megabytes free space.

451 megabytes / 4.1 megabytes per second = 110 seconds

It would take an additional 110 seconds to completely fill up the flash drive.

Which of the following is a polynomial with roots: − square root of 5 , square root of 5 , and 3? (6 points)
Karo-lina-s [1.5K]

Let's check the first polynomial , that is

P(x)= x^3 -3x^2 -5x+15

We need to factor it first and for that we have to do grouping and factoring .

P(x) = x^2(x-3)-5(x-3) \\ P(x) = (x^2 -5)(x-3)

TO find the roots, we need to set P(x) to 0, that is

(x^2 -5)(x-3)=0 \\ x^2 - 5= 0 , x-3 =0 \\ x^2 = 5 , x=3 \\ x = \pm \sqrt{5} , x=3

SO the correct option is A .
