evaluate 6a+4 when a=12

Answer:

x= 27/5

Step-by-step explanation:

Answer:

y= 125

Step-by-step explanation:

You can find all the other angles knowing a straight line is equal to 180 degrees. The middle pentagon all adds up to 540 degrees. Once you've found the other sides add them all up and subtract 540 from it and you get 55. Now you do 180-55 one last time to give you y and Y = 125

Answer: y = 125°

Step-by-step explanation:

1) As shown in the picture, I drew a circle for every intersecting point that indicated it would sum up to 360 degrees, so I could find the degrees inside the pentagon.

2) When I had all of the degrees inside the pentagon (except for the corner in the far right), I added all of them together to the sum of 485 degrees.

3) Since all of a pentagon's angles need to add up to 540°, I was left with this equation: 485° + __ = 540°

4) To find the last degree of the pentagon or fill in the blank, I subtracted 540° and 485° to get 55°. The degree in the far right of the pentagon was 55° degrees.

5) I had 55° and 180° to answer what y was. Then again, the circle of intersected lines should all add up to 360°. To get y, I added 55° and 180° to get 235° -- and subtracted 360° and 235° to get 125°.

6) Then, my final answer: y is 125°.

I finally got to answer after my hard work !!  

Answer:B. Yes; the triangles are congruent by ASA.

Step-by-step explanation:

In triangle ACD and CAB, AB || CD and AC ≅ BD, B. Yes; the triangles are congruent by ASA.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.

Given,

In triangle ACD and CAB, AB || CD and AC ≅ BD.

Therefore, The triangles ACD and CAB are congruent by ASA as ∠A is congruent to ∠C, Side AB is congruent to side CD and ∠B is congruent to ∠B.

Answer:

all of them....take -5, -5*5+8=-25+8,definitely negative....and if -5 is negative, other more extreme options are even more negative

Step-by-step explanation:

Y= -1/3x +5

5 is the y-intercept (where the line touches the y-axis) and -1/3 is the slope (rise over run, but since its negative, you go down 1, over 3 to the right) Hope this helps!!!

x+y=21 --> y=-x+21

20x+100y=1460

20x+100(-x+21)=1460

Complete question :

Jordan is mixing water and flour to make tortillas. The number of cups of water, w, needed for f cups of flour is described by the equation w = 0.75f

How many cups of water are needed to mix with 4 cups of flour?

Answer:

3

Step-by-step explanation:

Given the relation :

w = 0.75f

Where w = number of cups of water ; f = cups of flour

Cups of water needed to mix 4 cups of flour :

f = 4

w = 0.75(4)

w = 3

Hence, 3 cups of water is required to mix 4 cups of flour.

Answer:

x = 7

Step-by-step explanation:

y = 4 is a horizontal line that passes through the point (0, 4).

A line perpendicular to y = 4 is a vertical line.

In a vertical line, all points have the same x-coordinate.

Since the point (7, 2) is on the vertical line we want, and its x-coordinate is 7, then x-coordinate of all the points on the line we want is 7.

Answer: x = 7

Answer:

A₁ = x²* ( 1 -  π /2)  square units

Step-by-step explanation:

Let´s call the area of the region that is inside the square but not inside the circle A₁

And the area of the square A(s)

And the area of the circle A(c)

Then  the area we are looking for is:

A₁  =  A(s) - A(c)

If the circle has a radius   r then

A(c) = π*r²

A(s) = x²

In the square diagonal of the square is d = √ x² + x²  ;  d = √2 * x

Half of this distance is  d/2 = (√2 /2)*x

There is a right triangle with points:

o The center of the square (which is the center of the circle)

a  Any of the corners of the square

b  Middle point of a side of the square

According to that

r the radius of the circle is:

r² + (x/2)²  = (d/2)²

r² + (x/2)²  = [ (√2 /2)*x]²

r²   =  (2/4)*x² - x²/4

r²   = (x²/2) - x² / 4

r²   = (1/2)*x²

r  =  x/√2

Then the area of the circle is

A(c) = π * r²

A(c) =  π * x²/2

And  A₁  = x² -  π * x²/2

A₁ = x²* ( 1 -  π /2)  square units  or   A₁ =[ ( 2 -  π)/2 ]*x²

Step-by-step explanation: It's important to understand that the sum of the measures of the interior angles of a triangle is always 180 degrees.

So let's first add up the measures of the two angles we know.

So we have 30 + 4 which is 75 degrees.

The missing angle will be equal to 180 minus 75.

So the missing angle measure is 105 degrees.
