(3x-4)(x+5)= I need help with this fast

Answer:

Step-by-step explanation:

Expresar lo siguiente como fracciones.

a) Los 4 meses del año

Hay 12 meses en un año. Entonces, la fracción de 4 meses de 12 meses en un año es:

= 4/12

= 1/3

b) Un día de la semana

Hay 7 días en una semana.

Así, la fracción de 1 día en una semana será:

= 1/7

c) Las tres provincias de la región Costa ecuatoriana

En la región de la Costa Ecuatoriana, hay cinco provincias presentes.

Ahora, la fracción de tres provincias del total de cinco provincias de la región de la Costa Ecuatoriana será:

= 3/5

Answer:

Given statement is false

Step-by-step explanation:

Given:

sin 53° = cos 8°

True/False

Computation:

sin 53° = cos 8°

sin (90-37)° = cos 8°

cos 47° ≠ cos 8°

So,

Given statement is false

Answer:

15) m∠A = 21°, m∠B = 125°, m∠C = 34°

16) m∠J = 48°, m∠K = 57°, m∠L = 75°

Explanation:

15) m∠A is thirteen less than m∠C, so if you were to translate that into numerical terms, it would be (x-13). m∠B is eleven less than four times m∠C, so that would be (4x-11). Because the angles of a triangle sum up to 180°, the equation for this scenario would be (x-13)+(4x-11)+x=180. (X is a variable for m∠C. Add all the like terms to get 6x-24=180. Add 24 to both sides to get 6x=204. Divide 6 on both sides to get x=34. Now that we know m∠C, we can substitute 34 into x to get m∠A as 21° and m∠B as 125°.

16) m∠K is 9 more than m∠J, which is (x+9). m∠L is 21 less than twice m∠J, which is (2x-21). Again, a triangle's angles sum up to 180°, so the equation would be (x+9)+(2x-21)+x=180. Add the like terms to get 4x+(-12)=180. Add 12 to both sides to get 4x=192. Divide 4 on both sides to get x=48. Substitute 48 for x to get m∠K = 57° and m∠L=75°.

Answer:

720 grams of flour.

10.8 grams of salt.

14.4 grams of yeast

36 ml of oil.

Step-by-step explanation:

The recipe is:

600g flour

9g salt

12g yeast

30ml oil

500ml water

Now we use 600ml of water.

We can take the quotient between the amount of water we use and the amount of water in the recipe, this is:

600ml/500ml = 1.2

Then the ratio between the quantities we need to use and the quantities un the recipe should be always 1.2

Or the quantities that Eli needs to use will be 1.2 times the ones shown in the recipe.

Then she needs to use:

1.2*600g flour = 720 grams of flour.

1.2*9g salt = 10.8 grams of salt.

1.2*12g yeast = 14.4 grams of yeast

1.2*30ml oil = 36 ml of oil.

Answer:

70 cents

Step-by-step explanation:

lol mark as brainliest ig

Answer:

See explanation

Step-by-step explanation:

First, determine how many cents are in a dollar.

Now, it says you spent 30 cents, meaning you do not have that money anymore.

This means you must take "cents in a dollar - 30"

The answer you get is how much you have left! Feel free to check with me once you have calculated your answer!

Step-by-step explanation:

Answer:

y = 1/4 x - 1/2

Step-by-step explanation:

Remark

The general equation for a line is y = mx + b

You know that m = 1/4. The problem is what do you do about (2,0)?

Solution

y = 1/4 x + b                  Let x = 2 when y = 0

0 = 1/4 * 2 + b               multiply 2 * 1/4

0 = 1/2 + b                     Subtract 1/2 from both sides

b = - 1/2

equation y = 1/4 x - 1/2

Answer:

Triangle WRD's angles are all 60 degrees, angle W and angle R and angle D.

Triangle WRD is an equiangular, equilateral triangle. It is also an acute triangle, as all angles are less than 90 degrees.

Step-by-step explanation:

You are told that WRD has all equal sides, each 3 inches long.

In a triangle, if sides are equal, then the opposite angles are also equal. So if ALL the sides are equal, then ALL the angles are equal.

The sum of the interior angles in a triangle is always 180 degrees. Since the trhee angles are all equal and they must add up to 180 degrees, 180/3 =60, so the angles must all be 60 degrees.

Triangle are classified by sides as

*** scalene = no equal sides

*** isosceles = two equal sides

*** equilateral = all equal sides

Triangles are classified by angles as

*** right triangle = one 90 degree angle

*** obtuse triangle = one angle larger than 90 degrees

*** acute triangle  = all angles less than 90 degrees

*** equiangular = all angles equal

There can be overlap in the categories, like an acute triangle also being equiangular.

Answer:

.9

Step-by-step explanation:

-1(t+8) = -7.1

PEMDAS

So times the parenthesis by -1

-t - 8 = -7.1

Add the 8 to itself to get rid of it

Then since you added it on the left, add it to the right

-t = .9

t = .9

Answer:

y = -x -1

Step-by-step explanation:

x1= 0, y1= -1

[tex]slope = \frac{x - x1}{y - y1} = \frac{x - 0}{y - ( - 1)} = \frac{x}{y + 1} [/tex]

-1 = x/(y+1)

-1 (y+1) = x

y+1 = -x

y= -x -1

Answer:

y=2/3x +5

Step-by-step explanation:

to find the gradient

9--1/6--9

10/15

2/3

y-y1=m(x-x1)

y-9=2/3(x-6)

y-9=2/3x-4

y=2/3x+9-4

y=2/3x+5
