Answer 1

Answer:
Each paper cup is a cone.
The volume if a cone is (1/3) (pi) (radius)² (height)

Notice, in the picture they labeled the diameter of the cup = 8 cm.
But we need the radius. that's 1/2 of the diameter = 4 cm.

So, the volume of these paper cups is

   (1/3) (pi) (4cm)² (11 cm) = about 184 cm³
=====================

It says that tons of lemons have been sacrificed, and you have
about 37,850 cm³ of lemonade.

How many cups will that fill ?

   37,850 cm³ / 184 cm³ = about 205 cups.
========================

How many packs of cups do you need to buy ?
Unfortunately, they only come in packs of 50.

1 pack = 50 cups . . . . . not enough
2 packs = 100 cups . . . not enough
3 packs = 150 cups . . . not enough
4 packs = 200 cups . . . oh so close but still not enough

You need to buy 5 packs = 250 cups.
=================================

It started raining, so you only sold 80% of the lemonade that you had.

80% means 0.80
"of" means "times"

You started out with 37,850 cm³ .

You sold (0.8) x (37,850 cm³) = about 30,280 cm³ of it.

How many cups did you fill with that much lemonade ?
(Remember, each cup holds about 184 cm³.)

   30,280 cm³ / 184 cm³ = about 164 cups sold.

You bought 250 cups to start out.
You sold 164 cups of lemonade.

You had (250 bought - 164 used) =

   86 clean, unused paper cups, still in the wrappers, left over.

Answers

I don't think so, because "acute angle" means "an angle less than 90 degrees". A right angle is exactly 90 degrees.

A regular hexagon (6-sided figure) has sides that are all the same length.

What are the side lengths of a rectangle if the area = 40 in and the perimeter = 48 in

Answers

4, 10, 4, 10. 10*4 gives area of 40. 10+10+4+4 gives 48 as shown in question

$a,b-the\ side\ lengths\ of\ a\ rectangle\n \na\cdot b=40\ [in^2]\ \ \wedge\ \ \ 2\cdot(a+b)=48\ [in]\n \n a+b=24\ \ \ \Rightarrow\ \ \ a=24-b\ \ \ \Rightarrow\ \ \ ab=(24-b)b=24b-b^2\n \nab=40\ \ \ \Rightarrow\ \ \ 24b-b^2=40\ \ \ \Rightarrow\ \ \ -b^2+24b-40=0\ /\cdot(-1)\n \nb^2-24b+40=0\ \ \Rightarrow\ \Delta=(-24)^2-4\cdot40=576-160=416=16\cdot 26\n \n$

$√(\Delta) =4 √(26) \ \ \ \Rightarrow\ \ \ b_1= (24-4 √(26) )/(2)=12-2 √(26)\ \Rightarrow\ a_1=12+2 √(26) \n \n.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ b_2= (24+4 √(26) )/(2)=12+2 √(26)\ \Rightarrow\ a_2=12-2 √(26)$

5t 8=43 whats t.I WILL GIVE 50 POINTS AND IF YOU DONT RECEIVE THE POINTS TELL ME AND I WILL GIVE THEM.PLZ HELP MEEEEEEEEEEEEEEEEEEEEEEE

Answers

==> I can't be sure of the equation. There's a blank space
      between '5t' and '8', where an operation must be.
   I think the operation is more likely ' + ' (addition). Brainly usually
   does show the ' - ' if it's subtraction, but goes blank if it's addition.
   Tell you what I'll do: Since you sound so desperate, and you're being
   so generous with your points, I'll show you how to figure it out both ways.

----------------------------------------

If it's subtraction:    5t - 8 = 43

Add 8 to each side: 5t = 51

Divide each side by 5 : t = 51/5

   t    = 10 and 1/5

--------------------------------------------

If it's addition: 5t + 8 = 43

Subtract 8 from each side:   5t = 35

Divide each side by 5 : t    = 7

t = 10 and 1/5 i think
