Mathematics
1 answer:
MA_775_DIABLO [31]3 years ago
8 0

Step-by-step explanation:

step 1. there are 3 right triangles!

step 2. 8/6 = 6/x (definition of right triangle with an altitude)

step 3. 8x = 36 (cross multitude)

step 4. x = 9/2 (divide both sides by 8)

step 5. 6^2 + x^2 = y^2 (pythagorean theorem)

step 6. 6^2 + (9/2)^2 = y^2

step 7. 144/4 + 81/4 = y^2

step 8. 225/4 =y^2

step 9. y = 15/2 = 7.5.

Please help me<br><br> Determine the value of base b if (152)b = 0x6A. Please show all steps.
egoroff_w [7]

Answer:

The value of b is, 8

Step-by-step explanation:

To determine the value of b:

Given:

(152)_b = 0x6A               ....[1]

Since, 0x6A represents the hexadecimal form.

To convert this hexadecimal form into decimal form:

(6A)_{16}= (6 \times 16^1)+(A \times 16^0)=(6 \times 16)+(10 \times 1) =96+10 = 106

⇒0x6A=106(decimal form)

Now we have to convert this decimal form into octal

8  |  106

8   |  13   | 2

    |   1    |  5

        1

Then, the octal form we get, (152)_8

Substitute this in [1] we have;

(152)_b = (152)_8

On comparing both sides we have;

b = 8

Therefore, the value of b is, 8
