Answer:
Tina's age = 2 years
Step-by-step explanation:
Tina's age = x
Michelle's age = 3 * x = 3x
Tina is 4 years younger than Michelle.
x = 3x - 4
Add 4 to both side
x +4 = 3x
Subtract x from both sides
4 = 3x - x
4 = 2x
Divide both sides by 2
4/2 = x
2 = x
Tina's age = 2 years
Answer:
She got 7 correct in multiple choice and 24 out of T/F
Answer:
Step-by-step explanation:
The radius of a circle is independent of the location of its center, and circles are always similar. Here, therefore, the circles are similar; their shapes are exactly the same. Only the radii differ from one another. The radius of Circle A is 3 and that of Circle B is 9; thus the radii differ by a factor of 3.
Answer:
10
Step-by-step explanation:
Answer:
- A)
kilobytes - B)
megabytes - C) In order to convert the number of bytes per unit to the number of bits per unit you need to multiply the number of bytes by 8.
Step-by-step explanation:
<u>Part A: How many kilobytes are there in 1 terabyte? The final answer should be left in exponential form.</u>
1 terabyte =
bytes
1 kilobytes =
bytes
⇒ 1 terabyte =
kilobytes
<u>Part B: How many megabytes are there in 1 petabyte? The final answer should be left in exponential form.</u>
1 megabyte =
bytes
1 petabyte =
bytes
⇒ 1 petabyte =
megabytes
<u>Part C: Another unit used to measure computer memory is a bit. There are 8 bits in a byte. Explain how you can convert the number of bytes per unit to the number of bits per unit.</u>
In order to convert the number of bytes per unit to the number of bits per unit you need to multiply the number of bytes by 8.
1 byte = 8 bits
2 bytes = 2*8 bits = 16 bits
3 bytes = 3*8 bits = 24 bits
etc.
