What is AC? Brainiest for answer

Answer:

120 degrees

Step-by-step explanation:

Answer:

6 students.

Step-by-step explanation:

3v +  c = 22  ---> c = 22 - 3v

2v + 4c = 28 ---> 2v + 4(22 - 3v) = 28

                         2v + 88 - 12v = 28

                       -10v + 88 = 28

                               - 88  - 88

                        - 10v = - 60

                              v = 6 students

Answer:

-1/36

Step-by-step explanation:

18=-1/(2k)

2k=-1/18

k=(-1/18)/2

k=(-1/18)(1/2)

k=-1/36

Answer:

5.5

Step-by-step explanation:

2x -3 = 8

then

2x = 8 + 3 = 11

means

2x = 11

then

x = 11 ÷ 2

x = 5.5

___________________

we change the sign (- or +)

then take the number to the other side of the equal (with the changed sign)

leaving the x alone so that we can answer the equation..

to make sure

2×5.5 -3 = .....

it will be 8

Answer:

In this case, the side lenghths don't even form a triangle. Since that is not an option, the triangle would be acute.

Step-by-step explanation:  

if c^(2 )> a^(2)+b^(2) then the triangle is obtuse.

if c^(2 )< a^(2)+b^(2) then the triangle is acute.

if c^(2 )= a^(2)+b^(2) then the triangle is right

Hope this helps :)

Answer:

204

Step-by-step explanation:

The area of the top triangle = 5*12/2 =                        30

The area of the bottom triangle =                                30

The hypotenuse of the top triangle is

5^2 + 12^2 = hypotenuse^2

25 + 144 = hypotenuse^2

169 = hypotenuse squared.

hypotenuse = sqrt(169)

hypotenuse = 13

Now the back face = 13 * 8 =                                       104

The area of the left side rectangular  face = 5*8 =     40

The total area = 30 + 30 + 104 + 40 =                        204

Step-by-step explanation:

f(x) = —x^2 – 3x

f(10)={-10}²-3×10=100-30=70

Answer:

f(10) = 70

Step-by-step explanation:

In this question, plug in "10" to "x" and solve.

Solve:

f(10) = -(10)^2 - 3(10)

f(10) = 100 - 3(10)

f(10) = 100 - 30

f(10) = 70

Your final answer would be f(10) = 70

Option 2  [tex]\frac{4\sqrt{6} }{3}[/tex]

Step-by-step explanation:

[tex]\frac{4\sqrt{2} }{\sqrt{3} } = \frac{4\sqrt{2} \sqrt{3} }{\sqrt{3}\sqrt{3} } = \frac{4\sqrt{6} }{3}[/tex]

Answer: I am pretty sure it is 2/1

Step-by-step explanation: rise/run

Answer: A is right. B is acute, C is obtuse, and D is right.

Step-by-step explanation:

The right triangles have the square in the corner.

Triangle C is a little bit bigger than a right triangle.

Triangle B is acute because its smaller than a right triangle.

Answer:

[tex]2.5h = 3g[/tex]

Step-by-step explanation:

Given

[tex]Sugar = 2\frac{1}{2}\ cups[/tex]

[tex]Bars = 3\ pans[/tex]

Required

Determine the equation for h pans and g cups

We have that:

[tex]Sugar = g[/tex]

[tex]Bars = h[/tex]

To do this, we make use of the following equivalent ratios.

[tex]Bars : Sugar = Bars : Sugar[/tex]

So, we have:

[tex]3 : 2\frac{1}{2} = h : g[/tex]

Express fraction as decimal

[tex]3 : 2.5 = h : g[/tex]

Express as fraction

[tex]\frac{3}{2.5} = \frac{h}{g}[/tex]

Cross multiply

[tex]2.5h = 3g[/tex]

No options were given. So, I will stop here

Image of triangle is missing, so i have attached it.

Answer:

x = 18

Step-by-step explanation:

From the diagram attached, we can see that the 3 given sides have dimensions of x, 16 and 30.

Also, we see the angle opposite the dimension of x is 30°

Thus,we can use law of cosine to fjnd the value of x. Thus:

x² = 16² + 30² - 2(16 × 30)cos 30

x² = 256 + 900 - (960 × 0.866)

x² = 324.64

x = √324.64

x = 18.02

Approximating to the nearest tenth gives; x = 18

Answer:

Sorry dude I don't know the answer.

Answer:

Alternate Interior ∠s: 3 & 5, 4 & 6.

Corresponding ∠s: 1 & 5, 2 & 6, 3 & 8, 4 & 7.

Alternate Exterior ∠s: 1 & 8, 2 & 7.

Consecutive ∠s: 3 & 6, 4 & 5.

Step-by-step explanation:

Alternate interior angles must both be in between the parallel lines, it is almost like you are flipping the angle over the line, then moving it down, if that makes any sense.

Corresponding angles correspond, which means that they are the same (of course), but it is like you go directly down to the similar angle. You can visually see that angles are the same, an example is 1 & 5.

Alternate exterior angles are similar to alternate exterior angles, but they must be on the exterior of the parallel lines. Once again, it is like you are flipping the angle of the line, then turning it downwards, if it makes any sense that way to you.

Consecutive angles are always in between the two parallel lines on the same side. They add up to 180. So 4 & 5 is a good example.

Good luck.

Answer:

[tex]\vec v = 2\cdot \vec a = \langle -4,6 \rangle[/tex]

Step-by-step explanation:

Let [tex]\vec a = \langle -2, 3 \rangle[/tex], we need to determine [tex]\vec v = 2\cdot \vec a[/tex], which can be found by applying the following property:

[tex]\alpha \cdot \langle x,y \rangle = \langle \alpha \cdot x, \alpha \cdot y\rangle[/tex], [tex]\forall \,\alpha,x,y\in \mathbb{R}[/tex] (1)

Then,

[tex]\vec v = 2\cdot \langle -2,3 \rangle[/tex]

[tex]\vec v = \langle -4,6 \rangle[/tex]
