1 answer:

7 0

The answers of this equation are 39/37 and 6/5. To get the answers, the equation of the problem becomes 9(9-8x)=2x+3 and 9(8x-9)=2x+3. Then next step is to simplify first equation 1,
81=74x+3.
After, equation 2 is simplified
70x=3+81

Una botella de agua de medio decimetro cubico se llena en 35 segundos .Con el mismo flujo de agua,¿En cuantos minutos se llenari

Amanda [17]

Answer:

5,250 minutes

Step-by-step explanation:

0.5 cubic Centimeter = 0.0005 liter

So, 4.5 liters = 4,500 cubic Centimeter

Time required for 0.5 cubic Centimeter = 35 seconds

So, we can calculate the total time required by using following formula

Total time required = (Time required for 0.5 cubic Centimeter × 2 ) × 4,500 cubic Centimeter

So, Total time required = (35 seconds ×2 ) × 4,500

= 70 × 4,500

= 315,000 seconds

= 5,250 minutes

Find the distance between the points A(13,2) and B(7,10)

Anna007 [38]

Answer:

$10 = D$

Step-by-step explanation:

Method #1

We can draw a right triangle on the graph upon where the points are located and use the Pythagorean Theorem:

${a}^{2} + {b}^{2} = {c}^{2}$

${6}^{2} + {8}^{2} = {c}^{2}$

$36 + 64 = {c}^{2}$

$100 = {c}^{2}$

$10 = c$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

_______________________________________________

Method #2

Or, we can use the Distance Formula:

$\sqrt{[-x_1 + x_2]^{2} + [-y_1 + y_2]^{2}} = D$

B[7, 10] A[13, 2]

$\sqrt{[-2 + 10]^{2} + [-13 + 7]^{2}} = D$

$\sqrt{8^{2} + [-6]^{2}} = D$

$\sqrt{64 + 36} = D$

$\sqrt{100} = D$

$10 = D$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

** You see? It does not matter which method you choose, as long as you are doing the work correctly.

I am delighted to assist you anytime.
