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

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.

A principal of $2900 is invested at 6.25% interest, compounded annually. How much will the investment be worth after 14 years?

Answers

Answer:

$6774.4

Step-by-step explanation:

Given data

P=$2900

r= 6.25%

t= 14 years

A=???

The compound interest formula is given as

A=P(1+r)^t

substiute

A= 2900(1+0.0625)^14

A= 2900(1.0625)^14

A= 2900*2.336

A= $6774.4

Hence the final amount is $6774.4

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
