Van found the change in a scale factor. His work is shown below. What error did Ivan make?

8090 [49]

Answer:

Ivan wrote the ratio incorrectly. The ratio should be written as the old length to the new length, so it should be 35

, which reduces to 7

. When going from larger to smaller dimensions, the change in the scale factor is a ratio that looks like an improper fraction, with a larger number in the numerator and a smaller number in the denominator.

On a math quiz, you earn 10 points for each question answered correctly. In the equation below, x represents the number of quest

nadya68 [22]

Answer:

The input value or independent variable is number of questions that you answer correctly on this quiz (variable x)

Step-by-step explanation:

Let

x ----> the number of questions that you answer correctly on this quiz

y ----> the total number of points you score on this quiz

In this problem

The output value or dependent variable is the total number of points you score on this quiz (variable y)

The input value or independent variable is number of questions that you answer correctly on this quiz (variable x)

we have

$y=10x$

This linear equation represent a proportional relationship between the variables x and y

where

k=10

K is the constant of proportionality or slope of the linear equation

What are the missing parts that correctly complete the proof

bonufazy [111]

Answer:

2. $\overline{AX}\cong \overline{BX}$

3. $PX \perp AB$ - definition of perpendicular

4. $\angle PXA \cong \angle PXB$ - all right angles are congruent

6. $\triangle AXP\cong \triangle BXP$

7. $\overline{PA} \cong \overline{PB}$

Step-by-step explanation:

Given: Point P is the perpendicular bisector of AB

Prove: P is equidistant from the endpoints AB

Proof.

1. Point P is on the perpendicular bisector of AB - given

2. $\overline{AX}\cong \overline{BX}$ - definition of bisector

3. $PX \perp AB$ - definition of perpendicular

4. $\angle PXA \cong \angle PXB$ - all right angles are congruent

5. $\overline{PX} \cong \overline{PX}$ - reflexive property of congruence

6. $\triangle AXP\cong \triangle BXP$ - SAS congruency postulate

7. $\overline{PA} \cong \overline{PB}$ - corresponding parts of congruent triangles are congruent

8. Point P is equidistant from the endpoints of AB - definition of equidistant

Arrange these units from smallest to largest: cm,um,km,mm,m,nm,dm,pm.

MrMuchimi

Arranging units from smallest to largest:
pm, nm, um, mm, cm, dm, m, km.

Individual measurements in terms of 1 meter.
1 x 10^12 pm = 1 m
1 x 10^9 nm = 1m
1 x 10^6 um = 1m
1 x 10^3 mm = 1m
1 x 10^2 cm = 1m
1 x 10^1 dm = 1m
1m = 1m
1 x 10^-3 km = 1m
