Answer 2

Answer:

Solution:

The greatest of Winnie's even numbers is $2\times 30 = 60,$ so her sum is

\[2+4+6+\cdots + 58 + 60.\]For Grogg's sum, there are five odd numbers between $0$ and $-10$, five between $-10$ and $-20$, and so on, so Grogg's sum is

\[(-1)+(-3)+(-5)+\cdots+(-57)+(-59).\]

We could compute these sums separately and find their difference, but instead, we'll look for a clever way to regroup to compute the difference

\[(2+4+6+\cdots +58+60)-((-1)+(-3)+(-5)+\cdots +(-57)+(-59)).\]Noting that Winnie's list steps up by 2 at each term while Grogg's steps down by 2 at each step, we write Winnie's list backwards, so that each list goes down by 2 at each step:

\[(60+58+56+\cdots + 4+2) - ((-1)+(-3)+(-5)+\cdots +(-57)+(-59)).\]Now, we see that the difference between a term in Winnie's backwards list and the corresponding term in Grogg's list is always the same:

\begin{align*}

60-(-1) &= 61,\\

58-(-3) &= 61,\\

56-(-5) &=61,\\

\vdots&\\

2-(-59) &= 61.

\end{align*}There are 30 such differences, so Winnie's sum is $30\times 61 = \boxed{1{,}830}$ greater than Grogg's sum.

I wil brainly anyone who answers this right with explination

Answers

Answer:

False

Step-by-step explanation:

I will use an example here:

Original price of a pc is $799

you use your 20% off coupon which will bring it down:

799 decrease 20% =

799 × (1 - 20%) = 799 × (1 - 0.2) = 639.2

then you use your 10% off coupon:

639.2 decrease 10% =

639.2 × (1 - 10%) = 639.2 × (1 - 0.1) = 575.28

our final price doing them separately is $575.28

while doing it in one step by subtracting 30%:

799 decrease 30% =

799 × (1 - 30%) = 799 × (1 - 0.3) = 559.3

our price by doing it with a 30% discount is $559.30

Noah wrote that 6+6 =12. Then he wrote that

6+6 -n =12 - n. Are his equations balanced? Explain.

Answers

Answer:

Hs equations are balanced

Step-by-step explanation:

To check whether both equations are balanced, we will simplify

6+6 -n =12 - n

Add n to both sides of the equation using additive property

6+6-n+n = 12-n+n

6+6 +0 = 12+0

6+6 = 12 (This gives the other equation)

Since they are both equal, this shows that the equations are balanced

Factorize the numerator

[tex]Scale = \frac{1.5 * (3,2)}{(3,2)}[/tex]

What is 16.281 rounded to the nearest whole number?

Answers

Answer:

16

Step-by-step explanation:

The round-off to the number 16.281 will be 16.

What is rounding off the number?

When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.

A number can be rounded off to its lower value if the number after the decimal is between 0 and 4. The number will be rounded off to its higher value if the number after it is between 5 and 9.

The given number is 16.281. The round-off to the number will be 16 because the decimal value is less than 5.
