Cole said that 555 rounded to the nearest ten is 600. What's coles error?

ki77a [65]

Cole's mistake was that he rounded 555 to the nearest hundred instead of the nearest ten. He should've rounded it to 560 because the tens place is the second number, not the first one.

The width of a rectangle is 14 cm less than

ratelena [41]

Answer:

the length should be 28.5 cm.

Step-by-step explanation:

i used the equation 2L+2W=P (or L+L+W+W=P)

(length + length +width + width = perimeter)

I plugged the given information into this equation so i had:

2L+(2L-14)=86

then i solved for L

(this is what that work would look like if you need it):

2L + 2(L - 14) = 86

1. distribute the 2 in 2(L-14):

2L + 2L - 28 = 86

2. combine like terms:

4L - 28 = 86

3. add 28 to both sides:

4L = 114

4. divide both sides by 4

L = 28.5

hope this helped :)

In what time will a sum of money double itself at 5 parcent compound interest payable half yearly

ella [17]

Answer:

The Time in which sum of money double itself is 14 years .

Step-by-step explanation:

Given as :

The principal money = P

The rate of interest = R = 5 % payable half yearly

The Amount = Double of principal

Let The time in which sum become double = t years

I.e A = 2 P

From Compounded method

Amount = principal × $(1+\dfrac{\textrm rate}{2\times 100})^{2\times \textrm time}$

or, 2 P = P × $(1+\dfrac{\textrm 5}{2\times 100})^{2\times \textrm t}$

Or, 2 = $(1.025)^{2 t}$

Or, Taking log with base 10 both side

So, $Log_{10}$ 2 = $Log_{10}$ $(1.025)^{2 t}$

or, 0.3010 = 2 t × $Log_{10}$ 1.025

Or, 0.3010 = 2 t × 0.010723

Or, 0.3010 = 0.021446 t

∴ t = $\frac{0.3010}{0.021446}$

I.e t = 14.03 years ≈ 14 years

So, The time period = T = 14 years

Hence The Time in which sum of money double itself is 14 years . Answer
