Yes 2,920 is the correct answer because if you divide 2,920 divided by 8 then you will get 365 days.

Yep.  If he says that by the end of a 365 day period he will have drank 2,920 glasses of water, then, if you divide 2,920 by 365 you will get the right answer of the average 8 glasses of water a day.

rusak2 [61]

Solution :

Given :

Principal amount, P = Rs. 1000

Time period = 12 months

The maturity value = Rs. 12,715

We know that,

$ SI = \frac{PTR}{100}$

$SI = 1000 \times \frac{n(n+1)}{2 \times 12} \times \frac{R}{100}$

$SI = 1000 \times \frac{12(12+1)}{2 \times 12} \times \frac{R}{100}$

SI = 65 R

So we know,

maturity value = principal amount + SI

12715 = 1000 + 65 R

65 R = 12715 - 1000

65 R = 11715

R = 18%        

So the rate is 18%

I answered this question and got the slope of -2/2... is that simplified to -2 or 2? Help ASAP!
zlopas [31]
I actually believe that the slope is -1/2. This is because you have to go up 1 and left 2. since going left means it is negative the answer would be -1/2.

Find the height of the cylinder whose volume is 1.54 cubic m and radius of the base is 70 cm
Vikki [24]
<h2 /><h2><u>Question</u><u>:</u></h2>

<u>find the height of the cylinder whose volume is 1.54 cubic m and radius of the base is 70 cm</u>

Required diagram :

\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{ 70 \: cm}}\put(9,17.5){\sf{h}}\end{picture}

<h3>Solution :</h3>

For a cylinder having a radius r and a height h ;

Volume Of Cylinder :

  • π r² .

Here , the radius of the cylinder is given as 70 cm and the volume is 1.54 m³ .

Converting ;

  • 1 m³ = 1 × 10⁶ cm³ .
  • > 1.54 × 10⁶ cm³ .
  • > 1540000 cm ³.
  • > π r² h = 1540000
  • > 22/7 × 70 × 70 × h = 1540000
  • > 22 × 10 × 70 h = 1540000
  • > 15400 h = 1540000
  • > h = 100 cm = 1 m.

<u>The</u><u> </u><u>height</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>cylinder</u><u> </u><u>is</u><u> </u><u>100cm</u><u>.</u><u>=</u><u>1m</u><u>.</u>

Solve using the quadratic formula.<br> – 2^2 + 3x + 7 = 0
Phantasy [73]

Answer:

x=−1

Step-by-step explanation

Step 1: Simplify both sides of the equation.

−22+3x+7=0

−4+3x+7=0

(3x)+(−4+7)=0(Combine Like Terms)

3x+3=0

3x+3=0

Step 2: Subtract 3 from both sides.

3x+3−3=0−3

3x=−3

Step 3: Divide both sides by 3.

3x

3

=

−3

3

x=−1
