There are 10 boys and 6 girls. How many ways are there to choose 8 people to get at most girls

Answer:

math = 87

physics = 168

Brainliest, please!

Step-by-step explanation:

Variables:

m = math, p = physics

Equations:

m + p = 255

m = p - 81

Substitution:

m + p = 255

(p - 81) + p = 255

2p - 81 = 255

2p = 336

p = 168

Solving for m:

m + p = 255

m + 168 = 255

m = 255 - 168

m = 87

Checking with the other equation:

m = p - 81

87 = 168 - 81

87 = 87

So, math = 87 and physics = 168

Answer:

2:3

Step-by-step explanation:

r_1^3:r_2^3=8:27

r_1:r_2=2:3

Answer:

2/3

Step-by-step explanation:

solve volume formula for r and then use v1 and v2 from the ratio to find r1 and r2

v = 4/3 Pi r**3

(3/4 v) / Pi = r**3

r = (3v/4Pi)**1/3

Then

r1 = (3*8/4pi)**3

   = (6/Pi)**1/3

   = 1.24

r2 = (3*27/4Pi)**3

   = (81/4Pi)**3

   = (6.45)**3

   = 1.8

Then

r1/r2 = 1.24/1.8 = .6666666 or 2/3

Answer:

{x | x is a real number}

Step-by-step explanation:

f(x) = 5x – 7

There are no restrictions on the value that x can take

The domain is all real numbers

Answer:

In the given expression, that is, f (x) = 5x - 7, we can say:

x satisfies all the real values starting from -∞ to ∞.

domain of 5x-7

Interval notation for f (x):

(- ∞ , ∞)

So, the domain will be all real numbers, as the function is a straight line, with no discontinuities, thus undefined at no value of x.

The equation in point slope form is y - 6 = 2(x + 3)

This is from the general point slope template of [tex]y - y_1 = m(x - x_1)[/tex]

The m is the slope, which in this case is m = 2. The [tex](x_1,y_1)[/tex] is the point the line goes through. In this case, [tex]x_1 = -3 \text{ and } y_1 = 6[/tex]

If you were to solve that equation in bold for y, then you should get y = 2x+12 which is now in y = mx+b form, aka slope intercept form.

Answer:

3 * 10 ^3

Step-by-step explanation:

Divide the numbers

3.9 / 1.3

3

Subtract the powers of 10

10^5 / 10^2 = 10 ^ (5-2) = 10^3

The result is 3 * 10 ^3

[tex] \frac{3.9 \times {10}^{5} }{1.3 \times {10}^{2} } \\ = \frac{3.9}{1.3} \times {10}^{5 - 2} \\ = 3.0 \times {10}^{3} [/tex]

Hope you could get an idea from here.

Hi

as the triangle is rectangle   isoceles, then the  three side are  :  

x , x , 6  where 6 is the  hypotenuse.  

So using pythagoras theorem we know that  :    x²+x² = 6²

                                                                                2x² = 36

                                                                                  x² = 36/2

                                                                                  x² = 18

                                                                                   x = √18

Answer:

x = (cy+b)/a

Step-by-step explanation:

ax-b=cy

Add b to each side

ax-b+b=cy+b

ax = cy +b

Divide each side by a

ax/a = (cy+b)/a

x = (cy+b)/a

Answer:

96 flowers did not bloom and 12 did.

Explanation:

Total flower = 108

Number of flower that bloomed

= ⅑ of the total flowers

= ⅑ of 108

= ⅑ × 108

= 108/9

= 12

So, number of flowers that did not bloom

= Total flowers - Number of flowers that bloomed

= 108 - 12

= 96

So, 96 flowers did not bloom and 12 flowers did.

Step-by-step explanation:

smaller triangle / bigger triangle = 20 / 28

hence,

4x = 40

x = 10

Answer:

Brauilo is wrong because he divided by (x+1) instead of (x-1)

Step-by-step explanation:

The remainder Theorem states that

if polynomial f(x) is divided by binomial x-a, the remainder will equal f(a). The factor is positive so the binomial is the same as

which is why we divide by -1, or subsitue -1 into the equation p(x).

The remainder of a polynomial division can be gotten using remainder theorem or synthetic division.

The true statement is: Brauilo did not find the value of a, because he divided by (x+1) instead of (x-1)

From the question, we have the following parameters:

[tex]\mathbf{p(x) = x^4 +5x^3 + ax^2 - 3x + 11}[/tex]

[tex]\mathbf{Divisor =x+ 1}[/tex]

[tex]\mathbf{Remainder = 17}[/tex]

First, we set the divisor to 0.

[tex]\mathbf{Divisor =x+ 1 = 0}[/tex]

So, we have:

[tex]\mathbf{x+ 1 = 0}[/tex]

Solve for x

[tex]\mathbf{x= -1}[/tex]

The above equation means that, the value of x that will be used to test the polynomial is -1

From the question,

Hence, Braulio is incorrect, because he used the wrong value of x
