The circumference of a circle is 2(3.14)r, and if 8.5 * 2 is 17, the answer will be 17*3.14.

An estimate is 51, and the actual answer is 53.38.

Answer:

C = 53.38 m

Step-by-step explanation:

The formula for circumference is

C = 2 * pi *r

we know the radius is 8.5 and we can approximate pi by 3.14

C = 2 * (3.14) * 8.5

C = 53.38 m

8x-8+3ax=5ax-2a<br>solve for a

Kisachek [45]

Answer:

a=4

Step-by-step explanation:

8x-8+3ax=5ax-2a

Get all the terms with a on the right side

Subtract 3ax from each side

8x-8+3ax-3ax=5ax-3ax-2a

8x-8 = 2ax -2a

Factor out an 8 on the left and 2a on the right

8(x-1) = 2a*(x-1)

Divide by (x-1) on both sides

8(x-1)/(x-1) = 2a*(x-1)/(x-1)

8 = 2a

Divide by 2

8/2 =2a/2

4 =a

Which best describes the error in finding the missing length of the triangle?

Paul [167]

Answer:

24 ft

Step-by-step explanation:

a^2 + b^2 = c^2

7^2 + b^2 = 25^2

7^2 - 25^2 = -b^2

49 - 625 = -b^2

-576 = -b^2

24 = b

Encik Zulhazim deposited RM8000 in a fixed deposit account at Bank T for 2 years with interest rate of 5% per annum. What is the

creativ13 [48]

Answer: $34.08

<u>Step-by-step explanation:</u>

$\text{Compound Interest}:A=P\bigg(1+\dfrac{r}{n}\bigg)^{nt}\\\\\bullet A=\text{accrued amount (final balance)}\\\bullet P=\text{principal (amount invested)}\\\bullet r=\text{interest rate (convert percentage to a decimal)}\\\bullet n=\text{number of times compounded (in one year)}\\\bullet t=\text{time (number of years)}\\\\\\\underline{\text{Given:}}\\\bullet P=8000\\\bullet r=5\% (0.05)\\\bullet n=3\ \text{(every 4 months is 3 times per year)}\\\bullet t=2$

$A=8000\bigg(1+\dfrac{0.05}{3}\bigg)^{3(2)}\\\\\\A = \large\boxed{8834.08}$

$\text{Simple Interest}:A=P(1+rt)\\\\A=8000+8000[1+0.05(2)]\\\\A=\large\boxed{8800.00}$

Difference = Compound Interest - Simple Interest

= 8834.08 - 8800.00

= 34.08
