A kilobyte is 2^10 bytes and a megabyte is 2^20 bytes. How many kilobytes are in a megabyte?
yawa3891 [41]

Megabyte is equal to 1 million bytes, while kilobyte is equal to 1000 bytes.

Divide 1,000,000 with 1,000

1000000/1000 = 1000

There are 1000 kilobytes in 1 megabyte.

MAXImum [283]

\underline{\ \ \ \ \ \ 123}\\1\ \ \ |15129\\\underline{\ \ \ \ \|1}\\22\ |\ 51\\\underline{\ \ \ \ |\ 44}\\243|\ \ 729\\\underline{\ \ \ \ \ |\ 729}\\.\qquad\ \ \ 0

\sqrt{15129}=123

The answer has to be a geometric proof. Thank you!
Mariulka [41]

Given data:

The given triangle in which AD is on perpendicular bisector on BC.

In triangle ABD and ACD.

\begin{gathered} \angle ADB=\angle\text{ADC}=90^{\circ} \\ BD=CD(\text{given)} \\ AD=AD\text{ (common)} \\ \Delta ABD\cong\Delta ACD(\text{SAS)} \end{gathered}

Simmilary triangle BED and triangle CED.

\begin{gathered} \angle BDE=\angle CDE \\ BD=CD \\ ED=ED \\ \Delta BED\cong\Delta CED(SAS) \end{gathered}

The fisr expression can be written as,

\begin{gathered} \Delta ABD\cong\Delta ACD \\ \Delta\text{ABE}+\Delta BED\cong\Delta ACE+\Delta\text{CED} \end{gathered}

Substitute CED in place of BED.

\begin{gathered} \Delta ABE+\Delta CED\cong\Delta ACE+\Delta CED \\ \Delta ABE\cong\Delta ACE \end{gathered}

Thus, the triangle ABE is congruent to trriangle ACE.

What percent of 20 is 36
jok3333 [9.3K]
36 is more than 20 so the percentage is more than a hundred and less than 200% since 36 is less than 40. So if u subtract 20 from 36 and find that 16 is 80% of 20 and so when you add 100% to it, its 180%

PLEASE HELP ASAP!!! Fill in a two-column proof for the following conjecture. Use the reasons in the bank below, you will not use
notsponge [240]

Answer:

2. Given

3. Definition of supplementary angles

4. Substitution Property

5 Subtraction Property

Step-by-step explanation:

2. Given

We are given in the statement that m<1 = 112°

3. Definition of supplementary angles

Supplementary angles definition: Two angles are supplementary if there sum is equal to 180°. That statement states:

m<1 + m<2 = 180°

4. Substitution Property

We put the value of m<1 = 112° in the equation. This is substitution property.

5. Subtraction Property

To find the value of m<2 we subtract 112 from both sides of the equation.

This is subtraction property.
