1 and 1/2
Working:
3/10 is less than 4/5, So take one part from 4 and add to 3/10
The new fraction=3 and 13/10 - 2 and 4/5
13/10 - 4/5 
LCD: 10
13/10 - 8/10
5/10= 1/2
Whole numbers 3-2 = 1

Gnom [1K]

Kriste respone is wrong

<em><u>Solution:</u></em>

Given that,

Kristen was asked to write each of the numbers in the expression 80,000 x 25 using exponents

Her response was (8 x 10 to the power of 3) x 5 to the power of 2

No, the response of Kristen is wrong

Let us first understand about exponents

An exponent refers to the number of times a number is multiplied by itself

Given expression is:

80000 \times 25

Here, 80000 has 4 zeros

Therefore, it can be raised as 10 power 4

80000 = 8 \times 10^4

<em><u>Thus the expression becomes:</u></em>

80000 \times 25 = 8 \times 10^4 \times 25

Also, 25 can be written as 5 power 2

80000 \times 25 = 8 \times 10^4 \times 5^2

Thus given expression is written as (8 x 10 to the power 4) x 5 power to the power 2

Thus Kristen respone is wrong, because he has raised 10 to power 3

Angles
coldgirl [10]
<h3>Answer: XWY and STR</h3>

I tend to think of parallel lines as train tracks (the metal rail part anyway). Inside the train tracks is the interior region, while outside the train tracks is the exterior region. Alternate exterior angles are found here. Specifically they are angles that are on opposite or alternate sides of the transversal cut.

Both pairs of alternate exterior angles are shown in the diagram below. They are color coded to help show how they pair up and which are congruent.

A thing to notice: choices B, C, and D all have point W as the vertex of the angles. This means that the angles somehow touch or are adjacent in some way due to this shared vertex point. However, alternate exterior angles never touch because parallel lines never do so either. We can rule out choices B,C,D from this reasoning alone. We cannot have both alternate exterior angles on the same exterior side of the train tracks. Both sides must be accounted for.
