Answer:

$588.

Step-by-step explanation:

You take $28,000 divide it by 100. Because you put your 2.1% above the 100 and x above the 28,000, you then cross multiply. Usually the teacher always called it butterfly method.

Hope this helps

If a photocopier makes copies in 1/3 s, then at the same rate, how many copies does it make in 4 minutes?
irina1246 [14]

Answer:

80 copies

Step-by-step explanation:

4 minutes= 240 seconds. So I did 240 seconds divided by 3 seconds (one copy is made in that time) then you get 80. I don't know if that explanation make sense but the math checks out.

Answer:

Account B

Value=$21,589.66

Step-by-step explanation:

#We determine the compounded amount after 10 years for each account using the formula:

A=P(1+i_m)^n, i_m=(1+i/m)^m-1, m-compoundings \ per \ year

#For account A:

Given principal is $16,000, i=3% and n=10, m=4:

(1+i_m)=(1+i/m)^m\\\\=(1+0.03/4)^4=1.03034\\\\\therefore A=16000(1.03034)^{10}\\\\=21573.75

#For account B:

Given principal is $16,000, i=3% and n=10, m=12:

(1+i_m)=(1+i/m)^m\\\\=(1+0.03/12)^{12}=1.03042\\\\\therefore A=16000(1.03042)^{10}\\\\\\\\=21589.66

We compare the amounts after 10 years and get the difference:

B>A\\\\B-A=21589.66-21573\\\\=\$15.91

Hence, account B has the most value after 10 years and has a value of $21,589.66

Building A is 255 meters taller than building B. If the height of building A is subtracted from twice the height of building B,
garri49 [273]

Answer:

A = 744 meters    B = 489 meters

Step-by-step explanation:

A = B + 255

2B - A = 234

-2B          -2B         Subract the -2B from both sides

-A = -2B + 234

A = 2B - 234          Divide by -1 to get A alone

B + 255 =  2B - 234   Set both equations equal to each other

- B              -B

255 = B - 234

+234      +234

489 = B

Plug 234 in for B in the original equations

A = 489 + 255

A = 744
