Answer 1

Answer: first we find width or legnth,
then we determine which wire is shortest
a wire=264

legnth used for rectangle=x

legnth used for square=264-x=y

reactangle=2legnh+2width=2(l+w)
l=2w-4
subsitute
2(2w-4+w)=recangle perimiter=4w-8+2w=6w-8

square=y
legnth=width
legnth=rectangleleghtn+width (rectangle l+w=3w-4)
4legnth=perimiter=12w-16

recangle perimiter=6w-8
square perimiter=12w-16
x+y=264
(6w-8)+(12w-16)=legnth of wire toatl
18w-24=total widght=264
18w-24=264
add 24 to both sides
18w=288
divide both sides by 18
w=16
perimter of square=4(l+w)
l=2w-4
l=2(16)-4
l=28
perimiter of square 4(28+16)=4(44)=176
176=y
x+y=264
x+176=264
subtract 176 from both sides
x=88
rectangle=88
88<176

rectangle is shorter wire which is 88 cm in total legnth

88cm is answer

29 - 7g = 3g + 9 =

PLEASE HELP!

Answers

Answer:

g=2

Step-by-step explanation:

29 - 7g = 3g + 9

move all the terms to the left, that means subtract it and set it equal to zero

29-7g-(3g+9)=0

Get rid of the parenthesis by grouping like terms together.

-7g-3g-9+29=0

Add all the numbers and variables.

-10g=-20

Divide by -10 on both sides

-10g/-10=-20/-10

Which gives you g=2

The height of a penny dropped from a 64-foot-tall bridge is modeled by the function h=-16t^2+64, where t is the time in seconds and h is the highest of the penny above the lake.Part AComplete the table of values below.

Height (ft), h | 64 | | | | |
Please tell me how you do the whole things thank yoy

For a sec, I thought this was AB Calculus with derivatives and second derivatives but it isn't! That's a good thing!

Anyhow, all the problem is asking is to plug in the values of time to find the height.

We see when time is zero, the height is 64 feet. Plug in zero for the "t" variable and you'll get 64 feet.

When the penny has dropped for half a second or 0.5 seconds, we know the "t" variable and plug in that value.

h = -16(.5)^2 + 64.
h = -16(.25) + 64.
h = -4 + 64.
h = 64 feet when the penny has dropped for half a second.

I encouraged student progression when given the knowledge to complete a problem. We know how to complete the rest of the table. Good luck!

A cell doubles every 15 minutes. If there is 1 cell at noon, how many cells will there be at 3 p.m.? Show work.

Answers

12:15 - 1+1 = 2
12:30 - 2 + 2 = 4
12:45 - 4 + 4 = 8
1 - 8 +8 = 16
1:15.......
.......
3 - 4096

okay so there is 1 cell and it starts doubling at 12:00 every 15 minutes that is 4 times every hour and there is three hours so 4 x 3 = 12 so it doubles 12 times then 12 x 2 = 24 so at 3pm that cell would have multiplied it self into 24 other cells
