give an example of an addition problem in which you would and would not group the addends differently to add

Answers

Answer 1
If you're adding positive numbers together, then the order in which you write or group the addends doesn't matter.

If you're "adding" a negative number to a positive number, it's a little easier to visualize this problem if you write the positive number first, followed by the negative number.

But if you're "adding" -15 to 8, it'd make sense to write the -15 first (because its magnitude is greater) and then the 8:  -15 + 8 = -7

A shop advertised a 23% off sale. If a coat originally sold for $258, find the decrease in price and sale price

Answers

The decrease in price would be $59.34. The sale price would be $198.66. I got the answer by multiplying $258• .23= $59.34. The decrease in price is $59.34. Then you subtract the $59.34 from the original price $258 and you will get $198.66 for the sale price. Hope that helps.
25% is .25
If you are taking 25% off a $1.00 item you would be taking off 25¢. You get that by multiplying 100¢ by .25. That is the decrese.
The sale price is $1.00 - 25¢

Danika is making necklaces.she has 512 silver beads and 278 blue.About how many more silver than beads does Danika have?

Answers

Daniela has 234 more silver beads than blue beads

Answer:

234 more silver beads.

Step-by-step explanation:

We have been given that Danika is making necklaces. She has 512 silver beads and 278 blue.

To find the number of silver beads is how much more than blue beads, we will subtract number of blue beads from silver beads.

[tex]\text{Number of more silver beads}=512-278[/tex]

[tex]\text{Number of more silver beads}=234[/tex]

Therefore, Danika has 234 more silver beads than blue beds.

The arcade has 3 pinball machines and 5 video games. If a person wants to play one pinball machine and one video game, how many different combinations of games could that person play?

Answers

Final answer:

The number of possible combinations of playing one pinball game and one video game, given there are 3 pinball machines and 5 video games available, is 15.

Explanation:

The subject of this question is combinatorics, a part of Mathematics that deals with combination and arrangement of objects. The question in essence is asking about the number of combinations one can play on a pinball machine and a video game in an arcade.

In the given context, there are 3 pinball machines and 5 video games. If a person wants to play one of each (one pinball game and one video game), we can calculate the number of combinations by simply multiplying the number of options for each game. That is, 3 pinball machines multiplied by 5 video games equals 15 different combinations.

So, there are 15 different combinations of games a person can play when selecting one pinball and one video game from the given sets.

two trains leave the station at the same time one heading west and the other East the westbound train travels at 55 miles per hour East bound train travels at 75 miles an hour how long will it take for the two trains to be 338 miles apart

Answers

recall your d = rt, distance = rate * time

so... one train goes west and the goes the opposite way... alrite... so... notice, by the time 338 miles have been covered by both, it will have been "t" hours, and whatever "t" is, is the same amount of time the westbound train has been running as well as the eastbound train has been running.

now, let's say, since by "t" hours they've covered 338 altogether, so, if the westbound train has covered say "d" miles, then the eastbound train would have covered the slack from 338 and d, that is, "338 - d".

[tex]\bf \begin{array}{lccclll} &\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\ &------&------&------\\ Westbound&d&55&t\\ Eastbound&338-d&75&t \end{array} \\\\\\ \begin{cases} \boxed{d}=55t\\ 338-d=75t\\ ----------\\ 338-\boxed{55t}=75t \end{cases} \\\\\\ 338=75t+55t\implies 338=130t\implies \cfrac{338}{130}=t\implies \stackrel{hours}{2.6}=t[/tex]

so, 2hours and 36 minutes.

Stan’s savings account has a balance of $1986. After 23 years, what will the amount of interest be at 4% compounded annually?
a.
$2908.93
c.
$2913.93
b.
$2899.93
d.
$794.40

Answers

1986*1.04^(23) = 4894.93


4894.93-1986 = 2908.93


Answer is A


Answer:

a.  $2908.93

Step-by-step explanation:

We have been given that Stan’s savings account has a balance of $1986. The amount of interest be at 4% compounded annually.

To find the final amount after 23 years we will use compound interest formula.

[tex]A=P(1+\frac{r}{n})^{nT}[/tex], where,

A = Final amount,

P= Principal amount,

r = Annual interest rate in decimal form,

n = Number of times interest in compounded per year,

t = Time in years.

Let us convert our given rate in decimal form.

[tex]4\%=\frac{4}{100}=0.04[/tex]

Upon substituting our given values in above formula we will get,

[tex]A=\$1986(1+\frac{0.04}{1})^{1*23}[/tex]

[tex]A=\$1986(1+0.04)^{23}[/tex]

[tex]A=\$1986(1.04)^{23}[/tex]

[tex]A=\$1986*2.4647155431651442[/tex]

[tex]A=\$4894.9250687259763812[/tex]

To find the amount of interest we will subtract principal amount from final amount.

[tex]\text{Amount of interest}=\$4894.9250687259763812-\$1986[/tex]

[tex]\text{Amount of interest}=\$2908.925068725976\approx 2908.93[/tex]

Therefore, the amount of interest after 23 years will be $2908.93 and option a is the correct choice.

What kind of transformation is illustrated in this figure?



dilation

rotation

reflection
Triangle D E F and another triangle D-prime E-prime F-prime is of the same size, shape but turned a different angle

Answers

the answer is rotation
Without the drawing, it's impossible to say for sure. However, it is definitely not a dilation because of the "same size" fact stated. If a dilation did occur, it would be smaller or larger than the original. This is also known as scaling.

So its either a translation, rotation or reflection. I don't think it's a translation because you mention how its "turned a different angle" so that suggests a rotation perhaps. Though that doesn't fully rule out a reflection. If you can please post the diagram so I can have a look.

Find the standard deviation for each data set. Which set is more variable?

Answers

Eastern States Standard deviation = 6440.2
Western States Standard deviation = 16178

The Western States is more variable because it has a higher deviation. Also you can tell that the Western States is more variable because the the data/numbers change more than the Eastern States.

Answer:

Second set.

Step-by-step explanation:

I put the formula of standart deviation in the image below.

x is each data of the list

μ is the data average

N is the amount of elements.

So, for the first list we have:

μ= [tex]\frac{28995+37534+31361+27087+20966+37741}{6}= \frac{183684}{6}=30614[/tex]

DE= [tex]\sqrt{\frac{|28995-30614|^{2}+|37534-30614|^{2}+|31361-30614|^{2}+|27087-30614|^{2}+|20966-30614|^{2}+|37741-30614|^{2}}{6} }[/tex]

= [tex]\sqrt{\frac{2621161+47886400+558009+12439729+93083904+50794129}{6} }[/tex]

= [tex]\sqrt{\frac{207383332}{6} }[/tex]

=  [tex]\sqrt{ 34563888.6667 }[/tex]

= 5879.1061.

For the other list of elements:

μ= [tex]\frac{72964+70763+101510+62161+66625+54339}{6}= \frac{428362}{6}=71393.66[/tex]

DE=[tex]\sqrt{\frac{|72964-71393.66|^{2}+|70763-71393.66|^{2}+|101510-71393.66|^{2}+|62161-71393.66|^{2}+|66625-71393.66|^{2}+|54339-71393.66|^{2}}{6} }[/tex]

= [tex]\sqrt{\frac{2465967.71+397732.03+906993934.99+85242010.67+22740118.19+290861427.71}{6} }[/tex]

= [tex]\sqrt{\frac{1308701191.3}{6} }[/tex]

=  [tex]\sqrt{218116865.21 }[/tex]

= 6029.32

Then, the second set is more variable.

so 1/5 of 1/7 goes to the American Cancer Society...." of " means multiply
1/5 * 1/7 = 1/35 <== 1/35 goes to the AMC

Final answer:

The American Cancer Society receives 1/35 of the total estate after it has been divided among relatives and other beneficiaries. This is determined by multiplying the fraction of the estate remaining (1/7) by the fraction of that remaining estate going to the Cancer Society (1/5).

Explanation:

The question states that six-sevenths, or 6/7, of the estate has been divided among relatives, which leaves one-seventh, or 1/7, of the estate remaining. It is this remaining fraction that is further divided, with one fifth, or 1/5, going to the American Cancer Society. To determine the fraction of the total estate that this represents, we multiply these two fractions together: [tex]1/7 * 1/5 = 1/35.[/tex] Therefore, the American Cancer Society receives one-thirty-fifth of the total estate.
