Explain how you know that7/13 is greater than one third but is less than two thirds

1 answer:

6 0

7/12 is greater than 1/3 but less than 2/3.
in order to find if this is true, you need to find the common denominator which is 12. in order for 1/3 to have a denominator of 12, you need to multiply by 4. but we all know the rule. whatever we do to the bottom needs to be done to the top, so 1/3 is = 4/12. 7/12 is greater than 4/12. we do the same to 2/3 and multiply the denominator by 4 and the numerator by 4 as well, and the result would be 8/12. if we compare, 7/12 is less than 8/12.

What is angle 1 and 5

Answer:

Step-by-step explanation:

Remark

This may be a little late, but it is well worth finding all the answers. It is a perfect test question.

You should solve the angles in this order 2 5 1 4 3. This is not the only order you could use.

Angle 2

<180 = <2 + 148 <2 and 148 are supplementary

<180- 148 = <2

<2 = 32

Angle 5

1) All triangles have 180 degrees.

2) Diagonal bisect each other and are equal.

3) The two sides (one of which is opposite angle 5 are equal.

x + x + 148 = 180 All triangles have 180 degrees

All rectangles have diagonals that are bisected and the bisected parts are equal.

2x + 148 = 180 Subtract 148

2x = 180 - 148

2x = 32 Divide by 2

x = 32/2

x = 16

But x is really <5

<5 = 16

Angle 1

<1 = <5 by the z property of angles associated with parallel lines.

Angle 4

Angle 4 and <5 are Complementary. They make up 90 degrees.

Angle 3

<2 + the two base angles in the triangle = 180 degrees

The two base angles are equal. Call them x.

x + x + 32 = 180

2x + 32 = 180 Subtract 32 from both sides

2x = 180-32

2x = 148 Divide by 2

x = 148/2

x = 74

<3 = 72

Which of the following linear equations represents the data chart?

BlackZzzverrR [31]

Answer: y = -x + 7

Step-by-step explanation:

The slope is $\frac{5-6}{2-1}=-1$ , so we know the equation is of the form $y=-x+b$ .

Substituting in the coordinates (1,6) to find b,

$6=-1+b\\\\b=7$

Thus, the equation is y = -x + 7
