Answer:

false

Step-by-step explanation:

5(3−x)+1 = 3(x+4)

15-5x+1=3x+12

16-5x=3x+12

+5x +5x

16=8x+12

-12 -12

4=8x

/8 /8

1/2=x

How much is 110 hours in days and hours

eimsori [14]

4 days and 14 hours.

Method I used:

1. Do 110÷24 and you should get <span>4.58333333333. Ignore the numbers after the decimal point, and write down 4 as your number of days.
2. Do 4</span>×24 (you should get 96) and subtract that from 110 (you'll get 14). The difference will be the number of hours.

Hope I helped! <3

Plsssssss belpppppppppp

Since that is a triangle the expression would be b x h / 2. So 12*12 = 144 / 2 = 72. The answer is 72.

A conical vessels with base radius 5 cm and height 24cm is full of water this water is emptied into a cylindrical vessel of base

Aliun [14]

Answer:

$2\ cm$

Step-by-step explanation:

$We\ are\ given\ that,\\Radius\ of\ the\ conical\ vessel=5\ cm\\Height\ of\ the\ conical\ vessel=24\ cm\\Hence,\\As\ we\ know\ that,\\Volume\ of\ a\ cone=\frac{1}{3}\pi r^2h\\Hence,\\The\ volume\ of\ the\ conical\ vessel=\frac{1}{3}\pi (5)^224= \frac{1}{3}\pi 25*24=200\pi \\Hence,\\The\ volume\ of\ the\ conical\ vessel=The\ amount\ of\ water\ filled\ in\ it\\Hence,\\The\ amount\ of\ water\ filled\ in\ the\ conical\ vessel=200\pi\\Lets\ consider\ the\ cylindrical\ vessel:\\Volume\ of\ a\ cylinder=\pi r^2h$

$As\ we\ are\ not\ said\ that\ the\ cylindrical\ vessel\ was\ empty,\ let\ its\ initial\\ height\ be\ h_1\\Radius\ of\ the\ Cylindrical\ vessel=10\ cm\\Initial\ height\ of\ the\ cylindrical\ vessel=h_1\\Initial\ volume\ of\ the\ cylindrical\ vessel=\pi *10^2*h_1=100h_1\pi \\Initial\ amount\ of\ water\ in\ the\ cylindrical\ vessel=100h_1\pi \\Hence,\\Final\ amount\ of\ water\ in\ the\ cylindrical\ vessel=Final\ amount\ of\ water\\ in\ the\ cylindrical\ vessel +Amount\ of\ water\ in\ conical\ vessel$

$Hence,\\Final\ amount\ of\ water\ in\ the\ cylindrical\ vessel=100h_1\pi +200\pi \\Now,\\Let\ the\ final\ height\ be\ h_2\\Hence,\\Final\ amount\ of\ water\ in\ the\ cylindrical\ vessel=\pi *10^2*h_2=100h_2\pi \\Hence,\\100h_2\pi =100h_1\pi +200\pi \\Hence,\\100h_2=100h_1+200\\100h_2-100h_1=200\\100(h_2-h_1)=200\\h_2-h_1=2\\Hence,\\As\ the\ rise\ in\ level\ is\ the\ difference\ between\ the\ initial\ and\ final\\ heights:\\The\ rise\ in\ level\ of\ water=2\ cm$

Compact discs (CDs) cost $12 each at the Music Emporium. The company charges $4.50 for shipping and handling, regardless of how

Lena [83]

Answer:

1 $16.50

2 $28.50

3 $40.50

$4.50 + $12c

$100.50

Step-by-step explanation:

Please find attached the complete question

Total cost in dollars = fixed cost + (variable cost x number of CDs bought)

fixed cost = $4.50

variable cost = $12

number of cds bought = c

total cost in dollars = $4.50 + $12c

total cost in dollars when 1 cd is bought = $4.50 + $12(1) = $16.50

total cost in dollars when 2 cds are bought = $4.50 + $12(2) = $28.50

total cost in dollars when 3 cds are bought = $4.50 + $12(3) = $40.50

total cost in dollars when 8 cds are bought = $4.50 + $12(8) = $100.50
