Please help me with this question!!
Find angle x and y.

Answer:

Should be 4/10

Step-by-step explanation:

If you add all the marbles up you get the total/denominator of 10. Then you find the fraction for orange marbles which is 2/10. Then the green, 2/10. Add the numerators and keep the denominator the same.

Answer:

[tex]a) - 6a + 70 - 11b[/tex]

[tex] b) - 17a - b[/tex]

Step-by-step explanation:

[tex]7a + 70 - 13a - 11b \\ 7a - 13a + 70 - 11b \\ = - 6a + 70 - 11b[/tex]

Answer:

Step-by-step explanation:

The solution of this systems of equations is the intersection of both graphs

Let's kick start with a:

a)

[tex]y+12 = x^2+x \\ \\ x+3 = y[/tex]

From the first attached diagram by using graph:

the solution is the set {(-5, 8), (3, 0)}

b)

[tex]y-15=x^3+4x \\ \\ x-y =1[/tex]

Using the graph tool from the last diagram below;

the solution is the set⇒( there is no solution)

c)

[tex]y+5 =x^2-3x \\ \\ 2x+y =1[/tex]

From the second attached diagram by using graph:

the solution is the set {(-2, 5), (3, -5)}

d)

[tex]y-6=x^2-3x \\ \\ x+2y =2[/tex]

the solution is the set ⇒ there is no solution (shown in the last diagram  below)

e)

[tex]y-17=x^2-9x \\ \\ -x+y =1[/tex]

the solution is the set {(2, 3), (8, 9)} as shown in the third diagram

f) Lastly:

[tex]y-15=-x^2+4x \\ \\ x+y =1[/tex]

Using the graph tool from the fourth diagram below;

the solution is the set  {(-2, 3), (7, -6)}

The solution to the system of equations are the truth values of the system of equations

[tex]\mathbf{(a)\ y + 12 = x^2 + x,\ x + 3 = y}[/tex]

The graphs of the equations intersect at (-5,8) and (3,0).

So, the solution set is {(-5,8), (3,0)}

[tex]\mathbf{(b)\ y - 15 = x^3 + 4x,\ x - y = 1}[/tex]

The graphs of the equations do not intersect

So, the system has no solution

[tex]\mathbf{(c)\ y + 5 = x^2 - 3x,\ 2x + y = 1}[/tex]

The graphs of the equations intersect at (-2,5) and (3, -5).

So, the solution set is {(-2, 5), (3, -5)}

[tex]\mathbf{(d)\ y - 6 = x^2 - 3x,\ x + 2y = 2}[/tex]

The graphs of the equations do not intersect

So, the system has no solution

[tex]\mathbf{(e)\ y - 17 = x^2 - 9x,\ -x + y = 1}[/tex]

The graphs of the equations intersect at (2,3) and (8,9).

So, the solution set is {(2, 3), (8, 9)}

[tex]\mathbf{(f)\ y - 15 = -x^2 + 4x,\ x + y = 1}[/tex]

The graphs of the equations intersect at (-2,3) and (7,-6).

So, the solution set is {(-2, 3), (7, -6)}

Answer:

x = 2.5

y = 6.5

Step-by-step explanation:

You can solve this by setting the two equations equal to each other, like so:

x + 4 = 3x - 1

Subtract x from both sides:

x + 4 = 3x - 1

-x         - x

__________

4 = 2x - 1

Add 1 to both sides:

4 = 2x - 1

+1        + 1

_________

5 = 2x

Divide by 2:

2.5 = x

Plug in 2.5 for x into the equation:

y = x + 4

y = 2.5 + 4

y = 6.5

Answer:

The point M(Mx, My) is mid-point of AB with A(Ax, Ay) and B(Bx, By).

=> 2*Mx = Ax + Bx => 2*2 = 0 + Bx => Bx = 4

=> 2*My = Ay + By => 2*(5) = -1 + By => By = 11

=> B(4, 11)

=> Option A is correct

Answer:

40 percent

Step-by-step explanation:

covert fraction 4 out of ten is 40 %

Answer:

40%

Step-by-step explanation:

A percentage is basically x/100.

Therefore, if we convert Siobhan's mark into a fraction, we get 4/10. Then, by converting the fraction to fit x/100, we get 40/100 (remember, we must do the same to both the numerator and the denominator, so in this case it's multiply them by 10). Now that we have x, we can fit that into the answer to get 40%.

We can't get a cross section in the form of a circle.

Option B. Cube

We can't get a cross section in the form of a cube.

Option C. Rectangle

When we slice a rectangular pyramid parallel to the base but not through the vertex, we get a Rectangle.

Option D. Square

We can not get a square by slicing a rectangular pyramid.

Option E. Triangle

By slicing a rectangular pyramid perpendicular to the base and passing through the vertex we can get the cross section in the form of  triangle.

Options C and E will be the answer.

Answer:

Height is 21cm

Step-by-step explanation:

Volume of the cylinder = 1029pi

Base area = 7x7xpi = 49pi

Therefor the height = 1029pi/49pi=1029/49 = 21cm

Answer:

21 cm.

Step-by-step explanation:

V = π r^2 h

1029π = π * 7^2 * h   The π is common so:

1029 = 7^2 h

h = 1029 / 49

= 21 cm.

Answer:

The number of boys: a

The number of girls: b

=> a/b = 5

   a - b = 60

=> (b + 60)/b = 5

=> b + 60 = 5b

=> 4b = 60 => b = 15 => a = 5 x 15 = 75

=> Total people:

T = a + b = 15 + 75 = 90

Answer:

Option A

Step-by-step explanation:

A domain of a function are all the inputs of the function. (or x-values)

The picture is a function mapping.

The left 'oval' contains the domain, as the right 'oval' contains the range.

The numbers in the left oval are [-1,3,5]. Therefore, they are the domain of the function.

Option A should be your correct answer.

Answer:

That is a quadratic equation in which

a = 1

b = 6

c = 3

The quadratic formula is:

x = [-b +- sqr root (b^2 -4*a*c)] / 2*a

x = [-6 +- sqr root (36 -4 * 1 * 3)] / 2

x1 = [-6 + sqr root (24)] / 2

x2 = [-6 - sqr root (24)] / 2

Step-by-step explanation:

a=-30 because -30-(8 x -30)=210.

Answer:

Step-by-step explanation:

The northbound car has traveled a distance of 6.2 miles.

Step-by-step explanation:

Step 1:

The eastbound car has traveled a distance of 5 miles and if a straight line is drawn between the two car's positions it would measure 8 miles.

This forms a triangle which has a hypotenuse measuring 8 miles while one of the other sides measures 5 miles.

Assume the distance traveled by the northbound car is x miles.

Step 2:

So the northbound car has traveled a distance of 6.244 miles. Rounding this off, we get 6.2 miles.
