Answer:

  • 6 and 4

Step-by-step explanation:

Let the numbers are x and y.

<u>Then the equations are:</u>

  • x + y = 10 (blue line)
  • x - y = 2 (red line)

<u>The graph are attached with the intersection marked: </u>

A farmer sold 35 bags of rice at 25 % profit. If he sold each bag for ?7500:00. How much was his profit on 25 of the lot.
Doss [256]
Suppose that the farmer had bought the rice at x dollars per bag and had sold them at a 25% markup.  How much did the bags cost him before he added the markup?  1.25x =$75 results in $75/1.25, or $60 per bag.

If he sold 25 bags, his profit would be 1.25($60/bag)(25 bags) = $1875.

I very seriously doubt that the rice was $7500 per bag.  Perhaps you meant $75/bag...?

1. What is the solution of n^2-49=0?
Effectus [21]

<u>Answer:</u>

<h2>1. a</h2><h2>2. b</h2><h2>3. b</h2><h2>4. b</h2><h2>5. 22</h2>

<u>Explanation:</u>

1.

n²-49=0

n=√49

n=7

2.

x²+64=0

x=√64

x=8

3.

if A=144x²

l = √A

l = √(144x²)

l = 12x

4.

b = (24×2)/3b

b = 48/3b

b = 16/b

b² = 16

b = √16

b = 4 in <em>(-4 is correct in algebra but there's no negative lengths in geometric shapes)</em>

5.

x²+z = 103

x² = 103-z

x = √(103-z)

for x = -9 and 9    (103-z) must equal 81

z = 103 - 81 = 22

x = √(103-22)

x = √81

x = -9 , 9

use the picture to write each ratio as a simplified fraction (how are you going to find the length of the third side?) show your
Butoxors [25]

Answer:

<h3>See below</h3>

Step-by-step explanation:

to figure out the ratios we must figure out the length of <u>hypotenuse</u> first to do so we can consider <u>Pythagoras</u><u> theorem</u> given by

\displaystyle  {a}^{2}  +   {b}^{2}  =  {c}^{2}

\displaystyle \implies c =  \sqrt{ {a}^{2} +  {b}^{2}  }

substitute:

\displaystyle c =  \sqrt{ {12}^{2} +  {9}^{2}  }

simplify squares:

\displaystyle c =  \sqrt{ 225 }

simplify square root:

\displaystyle c = 15

now recall that,

  • \displaystyle  \sin( \theta)  =  \frac{opp}{hypo}
  • \displaystyle\cos( \theta)  =  \frac{adj}{hypo}
  • \displaystyle   \tan( \theta)  =  \frac{opp}{adj}

the ratios with respect to angle w given by

  • \displaystyle  \sin( W)  =  \frac{12}{15}  =  \frac{4}{5}
  • \displaystyle  \cos(W)  =  \frac{9}{15}  =  \frac{3}{5}
  • \displaystyle  \tan( W)  =  \frac{12}{9}  =  \frac{4}{3}

the following ratio with respect to angle X

  • \displaystyle  \sin(X)  =  \frac{9}{15}  =  \frac{3}{5}
  • \displaystyle  \cos(X)  =  \frac{12}{15}  =  \frac{4}{5}
  • \displaystyle  \tan( X)  =  \frac{9}{12}  =  \frac{3}{4}
