2x= 138⁰

x= 138⁰/2

x= 69⁰

Answer:

25

Step-by-step explanation:

To solve this problem, you can use the pythagorean theorem, which is a^2 + b^2 = c^2 where a and b are legs and c is the hypotenuse. We can plug in the values of 15 and 20, and solve for c:

15^2 + 20^2 = c^2

225 + 400 = c^2

625 = c^2

c = 25

This means the hypotenuse is 25.

"Two-Fifths of a number is 48."

(2/5)n = 48

((2/5n)(5/2) = 48 *(5/2)

n = 120

------------------------------------

120 * (3/4) = 90

Hope this helps you.

Answer:

83 times.

Step-by-step explanation:

n + 3n + 8n = 240

12n = 240

n = 20.

So we have 20 reds in 240 spins

So by proportion the number expected in 1000 spins

= 20 * 1000/240

= 1000/12

= 83 1/3

So its 83 reds.

The graph of the system of equations:

Is the one in the bottom right.

Here we want to see which graph represents the system of equations:

So we have a linear equation that crosses the y-axis at y = 1, and a parabola that crosses the y-axis also at y = 1 (you can verify that by evaluating both equations in x = 0).

Only with that, we can conclude that the correct graph for the system of equations is the last one (bottom right graph)

From A draw AG // BC cuts CD at WO

We have: Trapezoid ABCD (assumption)

⇒ AB // CD

⇒ AB // GC (because G ∈ CD)

Considering quadrilateral ABCG, there are:

AB // GC (proven above)

AG // BC (assumption)

⇒ Quadrilateral ABCG is a parallelogram

⇒ AB = GC = 40 cm

AG = BC = 50 cm

We have: DG = CD - GC (because G ∈ CD)

DG = 80 - 40

⇒  DG = 40(cm)

Considering ΔAGD, there are:

Answer:

y=-5cos(pi/8(x+2))-21

Step-by-step explanation:

y=acos(b(x-c))+d

Let's find the max and then the min first. We are aiming to find the amplitude, a, which is the half the distance from the max to the min.

Max is y=-16

Min is y=-26

a=(-16--26)/2=-8--13=5

a could also tell us if y=cos(x) has been reflected about the x-axis if it is -5, which it looks like it has considering cos(0)=1 not -1.

I'm looking at the point (-2,-26) which is the lowest point of our curve and comparing it to our high point of (0,1) on y=cos(x).

So far we have, y=-5cos(b(x-c))+d.

Let's look at d, vertical shift. The average of our max and min is (-26+-16)/2=-13-8=-21.

So our vertical shift is d=-21.

So now equation is y=-5cos(b(x-c))+-21.

Now since we are using (-2,-26) as our (0,1) point on y=cos(x) then c=-2.

So now equation is y=-5cos(b(x--2))+-21

Now we are going to plug in a point haven't mentioned to find b. So looking at graph I will use (6,-16).

-16=-5cos(b(6--2))+-21

Add 21 on both sides:

5=-5cos(b(6--2))

Divide both sides by -5:

-1=cos(b(6--2))

Simplify inside:

-1=cos(b8)

Multiplication is commutative:

-1=cos(8b)

8b=pi * cos(pi)=-1

b=pi/8

The equation is

y=-5cos(pi/8(x--2))+-21

Simplify:

y=-5cos(pi/8(x+2))-21

They are similar

Answer:

a)2x-3y

b)4(9a-4)

Step-by-step explanation:

we want to expand the following expression:

[tex] \displaystyle - \frac{1}{4} ( - 8x + 12y)[/tex]

well to do so we consider distributive property thus distribute:

[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y)[/tex]

reduce fraction which yields:

[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y) \\ \\ \displaystyle 2x + ( - 3y)[/tex]

simplify Parentheses:

[tex] \displaystyle \boxed{ 2x - 3y}[/tex]

in the expression there's a common factor of 4 therefore factor it out:

[tex] \displaystyle 9.4a - 4.4 \\ \\ \displaystyle \boxed{4(9a - 4)}[/tex]

Answer:

Step-by-step explanation:

im not sure about 3 and 4 so yeh and sorry for responding late

Given:

If you divide any natural number n by 4, you get a remainder r.

To find:

The values of r if [tex]n=13;34;43;100[/tex]. Also find the domain and range.

Solution:

It is given that any natural number n by 4, you get a remainder r.

[tex]\dfrac{n}{4}=q+\dfrac{r}{4}[/tex]

Where, n is a natural number, q is quotient, r is the remainder.

For [tex]n=13[/tex],

[tex]\dfrac{13}{4}=3+\dfrac{1}{4}[/tex]

So, [tex]r=1[/tex].

For [tex]n=34[/tex],

[tex]\dfrac{34}{4}=8+\dfrac{2}{4}[/tex]

So, [tex]r=2[/tex].

For [tex]n=43[/tex],

[tex]\dfrac{43}{4}=10+\dfrac{3}{4}[/tex]

So, [tex]r=3[/tex].

For [tex]n=100[/tex],

[tex]\dfrac{100}{4}=25+\dfrac{0}{4}[/tex]

So, [tex]r=0[/tex].

Therefore, the required value are [tex]r=1,2,3,0[/tex] if [tex]n=13;34;43;100[/tex] respectively.

The domain of the function is [tex]\{13,34,43,100\}[/tex] and the range of the function is [tex]\{1,2,3,0\}[/tex].

Answer:

x=36

2x=72

4x=144

Step-by-step explanation:

Remember that the sum of all the inside angles of a triangle = 180

so angle E is 180-2x

and angle F is 180-4x

If you add angles E, F, and G, they need to add to 180.

substituting, we get 180-2x + 180-4x + x = 180.

Simplifying this, we get 180-5x = 0

and x=180/5 = 36

so if x=36, then 2x=72 and 4x=144

Answer:

36

Step-by-step explanation:

The angles of the triangle are going to be, (x), (180-2x), (180-4x)

and since the sum of the angles of a triangle is 180, then:

x + (180-2x) + (180-4x) = 180

-5x + 360 = 180

-5x = 180 - 360

-5x = -180 (Multiply both sides by -1)

5x = 180

x = 36

So, the three angles will be: 36, 144 and 72
