1 ¹¹/₂₀ liters of water.

<h3>Further explanation</h3>

<u>Given:</u>

  • Patrick drank ³/₄ liters of water on Wednesday before going jogging, and
  • ⁴/₅ liter of water after his jog.

<u>Question:</u>

How much water did Patrick drink altogether? Write your answer as a mixed number.

<u>The Process:</u>

We must add up the two fractions to find out how much water did Patrick drink altogether.

Previously, we must equate the denominator. We know that the least common multiple (LCM) of 4 and 5 is 20.

\boxed{ \ \frac{3}{4} + \frac{4}{5} = \ ? \ }

\boxed{ \ = \frac{3 \times 5}{4 \times 5} + \frac{4 \times 4}{5 \times 4} = \ }

\boxed{ \ = \frac{15}{20} + \frac{16}{20} \ }

\boxed{ \ = \frac{15 + 16}{20} \ }

\boxed{\boxed{ \ \frac{31}{20} \ }}

Let us change it into a mixed fraction.

\boxed{\boxed{ \ \frac{31}{20} = \frac{20}{20} + \frac{11}{30} \ }}

\boxed{\boxed{ \ \frac{31}{20} = 1 + \frac{11}{30} \ }}

Recall \boxed{\boxed{ \ a + \frac{b}{c} = a \ \frac{b}{c} \ }}

\boxed{\boxed{ \ 1 \ \frac{11}{20} \ }}

Thus, the amount of water that Patrick drank altogether is 1 \ \frac{11}{20} liters of water.

To find the total of 3/4 and 4/5 is to add them together. However, in order to add them together you need to find the least common denominator (LCD). And the LCD of both denominators would be 20, because that is the smallest number both 4 and 5 can divide into. And here is the tricky part, now you have to change the numerators. So since 3/4th's now has a denominator of 20 you have to make the 3 match the 20. So 4 times what it 20? It is 5. So now multiply 5 by three and that will give you 15/20, which can reduce to 3/4 which means that you did this correctly! Now repeat the same steps with 4/5:

4/5=4/20
20÷5=4
4•4=16
16/20    (16/20 can reduce to 4/5 which means you did this correctly.

Now to add them keep the denominators the same and only add the numerators:

15/20 + 16/20 = 31/20

Now this as a mixed number would be 1 11/20. I hope this was helpful!

(3x-9) +(x+19)+x=180
5x+10=180
-10=-10
5x=170
5 = 5
x=34

2x+(2x+10)+x=180
5x+10=180
-10=-10
5x=170
5 = 5
x=34

yes they are similar

When is 20% off better than 20$ off
Crazy boy [7]

Answer:

Price > 100$

Price > 150$

Step-by-step explanation:

Let us assume that x% off of price y$  is better than x$ off.

Hence, \frac{xy}{1000} > x  

Hence, y > 100

Therefore, when the price is more than 100$, then only x% off on the price is better than x$. (Answer)

Again, assume that 20% off on price y$ is better than 30$ off.

Hence, \frac{20y}{100} > 30

⇒ y > 150$

Therefore, when the price is more than 150$, then only 20% of on the price is better than 30$ off. (Answer)

I'll give more points here is what I need.
Serga [27]

Answer:

The answer to your question is x = 3; y = 3

Step-by-step explanation:

Data

angle = 45°

Opposite side = x

Adjacent side = y

hypotenuse = 3√2

To solve this problem, use trigonometric functions.

1) To find x, use the trigonometric function sine.

              sin Ф = Opposite side / hypotenuse

-Solve for Opposite side (x)

              Opposite side = hypotenuse x sin Ф

-Substitution

              Opposite side = 3√2 sin 45

-Simplification

               Opposite side = 3√2 (1 / √2)

               Opposite side = 3(1)

-Result  

               x = 3

2) To find y use the trigonometric function cosine

               cos Ф = Adjacent side / hypotenuse

-Solve for Adjacent side

                Adjacent side = hypotenuse x cos Ф

-Substitution

                Adjacent side = 3√2 x cos 45

-Simplification

                Adjacent side = 3√2 x (1/√2)

                Adjacent side = 3(1)

-Result

                y = 3
