Answer:

0.6

Step-by-step explanation:

To write 12/20 as a decimal you have to divide numerator by the denominator of the fraction. We divide now 12 by 20 what we write down as 12/20 and we get 0.6. And finally we have: 12/20 as a decimal equals 0.6.

A circle circumference is 600 M. what is the good approximation of the circle area

wlad13 [49]

Answer:

The area of the circle is 28662 M².

Step-by-step explanation:

Given:

Circumference of circle = 600 M.

Now, to find the area of the circle.

So, <em>to get the area we need to find the radius.</em>

By putting the formula of circumference we get the radius:

Let the radius be r.

Circumference = 2πr

$600 = 2\times 3.14\times r$ (taking the value of π = 3.14.)

$600=6.28r$

Dividing both sides by 6.28 we get:

$95.54=r$

Now, <em>for getting the area we put the formula:</em>

Area = πr²

$Area = 3.14\times 95.54^{2}$

$Area = 3.14\times 9127.89$

$Area = 28661.57$

So, <u><em>approximately the area of the circle = 28662 M²</em></u>.

Therefore, the area of the circle is 28662 M².

Someone please help, it was due yesterday UwU

irakobra [83]

Answer:

Step-by-step explanation:

Part A - Where did Phillip make a mistake? Justify your answer using complete sentences.

Use order of operation (PEMDAS)

He should multiply 8 x 4 first

Part B - Solve the expression correctly in the space below.

(5 x 9) - 8 x 4

= 45 - 32

= 13

Part C - Use the same rules of order of operations to solve the expression (8-4) +9 x 3. Explain your steps as you solve it.

(8-4) + 9 x 3

Step 1: 4 + 9 x 3 (Subtract in the parenthesis first)

Step 2: 4 + 27 (Multiply 9 x 3)

Step 3: 31 (Add)

Joe tracked the height of his Dalmatian puppy from age 13 weeks to 25 weeks. He graphed the data and determined the line of best

nadya68 [22]

Answer:

22.5 weeks

Step-by-step explanation:

y = 1.12x + 28.78 represents the height of the puppy. Here that height is 54 cm:

Then 54 = y = 1.12x + 28.78

Combining the constants, we get 1.12x = 25.22. Dividing both sides by 1.12, x turns out to be 22.5 weeks.

Which recursive sequence would produce the sequence 8,-35,137,…?

vagabundo [1.1K]

The recursive sequence that would produce the sequence 8,-35,137,… is T(n + 1) = -3 - 4T(n) where T(1) = 8

<h3>How to determine the recursive sequence that would produce the sequence?</h3>

The sequence is given as:

8,-35,137,…

From the above sequence, we can see that:

The next term is the product of the current term and -4 added to -3

i.e.

Next term = -3 + Current term * -4

So, we have:

T(n + 1) = -3 + T(n) * -4

Rewrite as:

T(n + 1) = -3 - 4T(n)

Hence, the recursive sequence that would produce the sequence 8,-35,137,… is T(n + 1) = -3 - 4T(n) where T(1) = 8

Emma puts $1000 in a savings account that pays 4% interest, compounded monthly. How much money will be in the account 3 years la

lorasvet [3.4K]

Answer:

Option A. $\$1,127.27$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=3\ years\\ P=\$1,000\\ r=0.04\\n=12$

substitute in the formula above

$A=\$1,000(1+\frac{0.04}{12})^{12*3}=\$1,127.27$
