In which number does the digit 3 have a value that is 10 times as great as the value of the digit 3 in 143,728?

Answers

Complete question :

In which number does the digit 3 have a value that is 10 times as great as the value of the digit 3 in 143,728? 137,982 142,398 292,389 392,097

Answer:

137,982

Step-by-step explanation:

The value of digit 3 in 143, 728

3 in 143,728 is in the 1000 thousand place, hence, digit 3 has a value of :

3 * 1000 = 3000

Therefore, 10 times the value of digit 3 will be :

3000 * 10 = 30000

Feom the options given, we obtain the option where 3 has a value of 30000 if the number is expressed in expanded form:

The answer is 137,982

3 here is in the 10 thousand place = 3 * 10,000 =. 30,000

y= 2/3x what is the slope

Answers

Answer:

the slope is −3 .

Answer:

2/3 (fact checking...)

Step-by-step explanation:

this is a problem constructed in Slope-Intercept form, the slope is the angle that the line plotted is at.

The intercept, aka the y-intercept is where the line crosses on the y axis, in this case since y is just y and not changed, the line crosses at 0 on the y coordinate.

The slope is 2/3 because when plotted, the line will cross the point on graph at the location (x,y) 2,3 as its nearest whole set of numbered coordinates to 0,0 along said line

Find the missing value so that the two points (-1, -1) and (x, 1) have a slope of 217.

for each sequence find the first 4 terms and the tenth term
a) n squared +3
b) 2n squared

Answers

Answer:

Step-by-step explanation:

Given that:

a) n³

The first 4 terms are;

let assume n = 1

1³ = 1

if n = 2

2³ = 8

if n= 3

3³ = 27

if n = 4

4³ = 64

So, the sequence is 1, 8, 27, 64

The tenth term of this sequence is: 10³ = 1000

b)

2n²

if the first term is 1

then 2(1)² = 2

if n = 2

2(2)² = 8

if n = 3

2(3)² = 18

if n = 4

2(4)² = 32

So, the sequence is 1, 8, 18, 32

The tenth term will be 2(10)² = 200

For questions 1-4, find the distance between points A and B. Round your solutions to the nearest tenth when necessary.

Answers

Answer:

1. AB= 8.94,

2. AB= 7.28

3. AB= 16.4

4. AB= 19.21

Step-by-step explanation:

This is fun! Well you have to find the (1,4) (or point e) point and count the distance to the other points point a and point b.

4 units from a to e and 8 b to e

a² + b² = c²

8² + 4² = c²

64 +16 = c

√80 = √c²

8.94 = c

It dose not matter which units you plug in for a and b but c has to be the long side of the triangle/ hypotonuse.

Follow the same steps for the rest of the problems.

On proplems 3 and 4 plot points first you can subtract the x-x and y-y as a short cut to find the units.
