Find the sum of two consecutive odd numbers is 56 find the numbers

ehidna [41]

Answer:

$\boxed{\sf 27 \ and \ 29}$

Step-by-step explanation:

Let the first consecutive odd integer be $\sf x$ .

Let the second consecutive odd integer be $\sf x+2$ .

The sum of the two numbers is 56.

$\sf x+x+2=56$

$\sf 2x+2=56$

$\sf 2x=54$

$\sf x=27$

Put x as 27 for the second consecutive odd integer.

$\sf 27+2=29$

The two numbers are 27 and 29.

John withdraws $40.00 from her savings account each month. What integer represents the net effect on her balance after 5 months?

lina2011 [118]

Answer:

The net effect of amount in John account after 5 months is $A - $200

Step-by-step explanation:

Given as :

The amount of money withdraws by John each month from his account = $40

Let The total amount of money did John had in his account = $A

Let the amount left in John account after 5 months of withdraw = $x

<u>So, According to question</u>

∵ Each month the money withdraw from account = $40

∴ In 5 months , the money withdraw = $40 × 5

I.e In 5 months , the money withdraw = $200

So, The left money in account after withdraw in 5 months = $A - The amount withdraw in 5 months

I.e x = $A - $200

So, The balance in account after 5 months = x = $A - $200

Hence, The net effect of amount in John account after 5 months is $A - $200 Answer

$\bf \textit{circumference of a circle}\\\\
C=2\pi r\qquad 
\begin{cases}
r=radius\\
-----\\
r=5x^2
\end{cases}\implies C=2\pi 5x^2\implies C=10\pi x^2
\\\\\\
\textit{area of a circle}\\\\
A=\pi r^2\qquad 
\begin{cases}
r=radius\\
-----\\
r=5x^2
\end{cases}\implies A=\pi (5x^2)^2\implies A=\pi (5^2x^{2\cdot 2})
\\\\\\
A=\pi (25x^4)\implies A=25\pi x^4$

Please I need help on this question.

Juli2301 [7.4K]

Answer:

126mm

Step-by-step explanation:

To find the diameter of the circle = circumference divided by pi = 56.52/3.14=18mm.

There are 4 circles = 18mmx4=72mm

Add on the 3x strips = 72+(18x3) = 126mm.

Hope this helps
