Marcos debe pintar 5/9 de la cubierta de un velero. Al acabar el día ha pintado 21/36 . ¿Ha conseguido cumplir su objetivo? ¿Ha pintado más? ¿Ha pintado menos?

Answers

Answer:

a) Have you managed to meet your goal?

Yes

b) Have you painted more? Have you painted less?

You have painted more.

Step-by-step explanation:

Marcos should paint 5/9 of the deck of a sailboat.

At the end of the day he painted 21/36.

Reducing this to the simplest form = 21/36

Dividing Numerator and Denominator by 3

= 7/12

Finding the difference between both fractions

= 7/12 - 5/9

The Lowest Common Denominator = 36

= 21 - 20/36

= 1/36

Therefore:

a) Have you managed to meet your goal?

Yes

b) Have you painted more? Have you painted less?

You have painted more.

Terms/Coefficients

Step-by-step explanation:

Step 1: Define

-29 = 9 - 6k - 2k - 1

Step 2: Solve for k

Combine like terms:                                                                                       -29 = 8 - 8k[Subtraction Property of Equality] Subtract 8 on both sides:                      -37 = -8k[Division Property of Equality] Divide -8 on both sides:                              37/8 = kRewrite/Rearrange:                                                                                        k = 37/8

Step 3: Check

Plug in k into the original equation to verify it's a solution.

Substitute in k:                                                                                                -29 = 9 - 6(37/8) - 2(37/8) - 1Multiply:                                                                                                           -29 = 9 - 111/4 - 37/4 - 1Subtract:                                                                                                          -29 = -75/4 - 37/4 - 1Subtract:                                                                                                          -29 = -28 - 1Subtract:                                                                                                          -29 = -29

Here we see that -29 does indeed equal -29.

∴ k = 37/8 is the solution to the equation.

What is the area of triangle ABC? a \large 6\sqrt{3} square units b \large 18\sqrt{3} square units c \large 36\sqrt{3} square units d \large 72\sqrt{3} square units

Answers

question isn't clear but I believe you are asking for the area of triangle ABC given sides a, b, c

We use the example question:

Find the area (in square units) of the triangle described.

a = 49mm, b = 33mm, c = 18mm

Answer and explanation:

We apply Heron's formula to solve the area of a triangle given the sides of the triangle a, b, c

A= √s(s-a)(s-b)(s-c)

Where A = area of triangle in square units

s= semiperimeter(a+b+c/2) of a triangle

a, b, c= lengths of the sides of the triangle

Therefore area of triangle =√50(50-49)(50-33)(50-18)

= √27200

=164.92mm²

Andre is making paper cranes to decorate for a party. He plans to make one large paper crane for a centerpiece and several smaller paper cranes to put around the table. It takes Andre 10 minutes to make the centerpiece and 3 minutes to make each small crane. He will only have 30 minutes to make the paper cranes once he gets home.
​Andre wrote the inequality 3x + 10 ≤ 30 to plan his time. Describe what x, 3x, 10, and 30 represent in this inequality.
Solve Andre’s inequality and explain what the solution means.

Answers

Answer:

6 small cranes

Step-by-step explanation:

3x + 10 is less than or equal to 30

3 is the minutes for the small cranes

X is the amount of small cranes

10 is the minutes for the large crane

30 is the total time limit

first, subtract 10 from 30, which gives you 20 so

3x is less than or equal to 20.

to figure this out, divide 20 by 3, which gives you 6 with a remainder of two minutes.

Andre can make 6 small cranes.

When salt and water are combined, they form a salt or saline solution. How much ml of water must be added to 150 mL of an 80% saline solution to produce a 30% saline solution?

Answers

Answer:

We must add 400 ml of water.

Step-by-step explanation:

We can use the following equation:

[tex]C_{i}V_{i}=C_{f}V_{f}[/tex]

Where:

C(i) is the initial concentration of the solution (80%)C(f) is the final concentration of the solution (30%)V(i) is the initial volume (150 ml)V(f) is the final volume

Now, we just need to solve the equation for V(f).

[tex]V_{f}=\frac{C_{i}V_{i}}{C_{f}}[/tex]

[tex]V_{f}=\frac{80*150}{30}[/tex]

[tex]V_{f}=400\: ml[/tex]

Therefore, we must add 400 ml of water.

Answer:

x = 7 √3 km

Step-by-step explanation:

Here, we want to get the value of x

As we can see, we have a right angled triangle with hypotenuse 14 km

we can use the Pythagoras’ theorem to get the value of x

Mathematically, the square of the hypotenuse equals the sum of the squares of the two other sides

Thus,

14^2 = x^2 + 7^2

x^2 = 196-49

x^2 = 147

x = 7 √3 km

10x -20 plus 7x plus 4 equals 180 what is x

Answers

Answer:

x is approximately 11.5

Explanation:

10x - 20 + 7x + 4 = 180

17x - 16 = 180

17x = 196

x is approximately 11.5

Step-by-step explanation:

The division of fraction 9/14 by 15/2 in simplest form is 3/70 by dividing both the numerator and the denominator by the GCD

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction. In this case, the reciprocal of 15/2 is 2/15. Therefore, we can rewrite the division as multiplication:

(9/14) * (2/15)

Next, we can multiply the numerators together and the denominators together:

(9 * 2) / (14 * 15)

Simplifying further, we get:

18 / 210

To simplify the fraction, we can find the greatest common divisor (GCD) of the numerator and the denominator, which is 6 in this case. Dividing both the numerator and the denominator by the GCD, we get:

18 ÷ 6 / 210 ÷ 6

This simplifies to:

3 / 35

Therefore, the division of 9/14 by 15/2 in simplest form is 3/70.

In summary, to divide fractions, we multiply the first fraction by the reciprocal of the second fraction. Then, we simplify the resulting fraction by finding the GCD of the numerator and the denominator and dividing both by the GCD. Applying these steps to the given fractions, we obtain the simplified form of 3/70.

Consider the relationship in special right triangles to determine the tangent ratio for a 45 degree angle. Give your answer, as necessary, to the nearest thousandth place (three decimal place values).

Answers

Answer:

1

Step-by-step explanation:

The tangent of a angle is opposite side/ adjacent side

In a rights triangle with a 45° angle we have a special 45-45-90 triangle.

The legs of the triangle are congruent and are the opposite and adjacent sides of the 45° angle.  Therefore, the ratio of those two sides is 1.

Therefore, the tangent of 45° = 1
