Answer:

Segment DE is half the length of segment AC. -- Substitution property of equality

Step-by-step explanation:

Here is given a proof for proving line joining mid segment is parallel and half the length of third side.

Stepwise proof is given in two columns

We find that for every line there is a justification as

STatement Justification

D and E coordinates found out MId point formula

DE and BC are measured Distance formula

DE=1/2 BC Substitution property of equality

This justification was missing in the given proof and with this included proof would be complete

What precent of 95 is 60.8

dezoksy [38]

60.8 is 64% of 95.

Step-by-step explanation:

Given number is;

We have to find at what percent, the value is 60.8

Let x be the percent.

Therefore;

x% of 95 = 60.8

$\frac{95x}{100}=60.8 \\0.95x=60.8$

Dividing both sides by 0.95

$\frac{0.95x}{0.95}=\frac{60.8}{0.95}\\x=64$

60.8 is 64% of 95.

Here is an expression: 2 + 3ⁱ ( Remember what you do when you replace i with a number) Evaluate the expression when i is 1.

Kamila [148]

Answer:

The value of the expression when i is 1 is equals to 5.

Step-by-step explanation:

We are given the following expression:

$2 + 3^{i}$

Evaluate the expression when i is 1.

We replace i by 1. When we elevate a number to the 1, the result is the number we elevate. So

$2 + 3^{i} = 2 + 3^{1} = 2 + 3 = 5$

The value of the expression when i is 1 is equals to 5.
