Which is bigger 49/54 or 8/9

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

Hope this helps!

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)}

To find the value c=(b/2^2,divide the coefficient of X by 2 and square the result.

Divide 12 by 2

(-6)^2

Raise -6 to the power of 2

Answer: 55.5 (A.)

Step-by-step explanation:

Since angle A = 29 and angle B = 41, angle C must be equal to 110

180 = m<A + m<B + m<C

180 = 29 +41 + m<C

180 = 70 + m<C

110 = m<C

Therefore, side c must be the longest, side b must be the second longest, and side a must be the shortest.

Since side length a, angle A, and angle B are known, one can use the law of sines to solve for side b.

Law of Sines: sinA/a = sinB/b = sinC/c

sinA/a = sinB/b

sin29/41 = sin41/b

b(sin29/41) = sin41

b = 41(sin41)/(sin29)

b = 55.48

b = 55.5

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%.

Answer:

24

Step-by-step explanation:

I will assume this is a right triangle with the information given

a^2+b^2 = c^2 is the Pythagorean theorem

18^2 + b^2 = 30^2

Subtract 18^2 from each side

18^2  - 18^2+ b^2 = 30^2 -18^2

b^2 =900 -324

b^2 =576

Take the square root of each side

sqrt(b^2) = sqrt(576)

b =24

Volume = 2448 cm3

Step-by-step explanation:

Volume = volume of cube + volume of pyramid

             = 12*12*12 + 12*12*15/3

             = 1728 + 720 =2448

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

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:

Yes, it's a right triangle.

Step-by-step explanation:

Use a^2 + b^2 = c^2

10^2 + 12.49 ^2 (its 2 39 square root) = 16^2

100 + 156 = 256

256 = 256

It ended up being equal to one another so yes, it is a right triangle.

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
