Answer:

  C)  31.2

Step-by-step explanation:

The length of AB can be found from the Pythagorean theorem:

  AB² = AD² +BD²

  AB = √(25 +144) = 13

All of the right triangles are similar, so ...

  BC/BD = AB/AD

  BC = BD(AB/AD) = 12(13/5)

Answer:

There will be 24 boys, 32 -8 = 24

Step-by-step explanation:

In the class there is 20 boys.

All these are alzebraic expressions. A monomial consists of only one term, binomial contains two terms and a polynomial is when the number of terms is two or more than two.

In the given question

There are 8 more boys than girls in a class of total 32 students

let the number of girls be x according to the given data boys will be (x + 8)

∴ {x + (x+8)} = 32

 2x + 8 = 32

 2x = 24

   x = 12

∴ the no. of girls = 12 and no. of boys = 12+8 = 20.

Answer:  (10,5)

Step-by-step explanation:

You have to graph it but the equations are

x+y=15 (total number of games and rides)

2x+4y+40 (total money spent)

first equation is also y= -x+15

second is 4y= -2x+40

                 y= -.5x+10

So graph y= -x+15 and y= -1/2x+10 and where the lines cross is your answer

also -x+15= -.5x+10

           15=.5x+10

           5=.5x

           10=x

10+y=15

y=5

Answer:

Since the length of the drawing is 200 ft. and equivalent to 13.33 in. with a scale of 15 ft to 1 in. and the length of the paper is 11 in., Adoncia's drawing will not fit on the sheet of paper

Step-by-step explanation:

The given parameters are;

The scale of the drawing is 15 ft = 1 in.

The actual dimensions of the monument;

Height = 80 ft.

Length = 200 ft.

Therefore, we have;

The required dimension of the paper height = 80/15 = 16/3 = 5.33 in.

The required dimension of the paper length = 200/15 = 40/3 = 13.33 in.

The given paper dimension by 11 in. which is of a dimension of that of a standard  letter paper size of 8.5 in. by 11 in.

Drawing length, 13.33 in. > Paper length > 11 in.

Adoncia's drawing will not fit on the sheet of paper.

Answer:

D (4)

Step-by-step explanation:

So we have the function:

[tex]f(t)=3t^2+5t+6[/tex]

And we want to find f(-3).

To do so, substitute -3 for x. Thus:

[tex]f(-3)=3(-3)^2+5(-3)+6[/tex]

Square:

[tex]f(-3)=3(9)+5(-3)+6[/tex]

Multiply:

[tex]f(-3)=27-15+6[/tex]

Add:

[tex]f(-3)=18[/tex]

So, our answer is D (4)

Answer:

Step-by-step explanation:

In this problem we are required to find the percentage decrease in the value of a car that originally cost $25,000

if the present value is now $14,000

we can solve for the percentage decrease by presentment the original cost of the car by the original cost and multiplying by 100

i.e = (14,000/25,000)*100

= (14/25)*100

= 0.56*100

= 56%

Hence the value of the car has decreased by 56%

Answer:

15th term = 116

Step-by-step explanation:

a= 4

Sum of an A.P = n/2 {2a + (n-1)d}

sum of first five term is equal to one-fourth of the sum of the next five term

5/2{ 2*4 + (5-1)d} = 1/4 × 10/2{2*4 + (10-1)d

5/2 {8 + 4d} = 1/4 × 5{ 8 + 9d}

40/2 + 20/2d = 1/4{ 40 + 45d)

20 + 10d= 40/4 + 45/4d

20 + 10d = 10 + 45/4d

20 - 10 = 45/4d - 10d

10 =45d - 40d /4

10 = 5/4d

Divide both sides by 5/4

10 ÷5/4 = d

10×4/5 = d

40/5 = d

8 = d

d= 8

Find the 15th term

15th term = a + (n-1)d

= 4 + (15-1)8

= 4 + (14)8

= 4 + 112

= 116

The 15th term is 116

Answer:

- x + 2y = 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (3, 2)

m = [tex]\frac{2-0}{3+1}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex], thus

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 2) , then

2 = [tex]\frac{3}{2}[/tex] + c ⇒ c = 2 - [tex]\frac{3}{2}[/tex] = [tex]\frac{1}{2}[/tex]

y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{1}{2}[/tex] ← in slope- intercept form

Multiply through by 2

2y = x + 1 ( subtract x from both sides )

- x + 2y = 1 ← in standard form

Calculus is the mathematical study of continuous change. Calculus is usually developed by working with very small quantities. Calculus has two major branches, which are,  differential calculus and integral calculus. Differential calculus involves instantaneous rates of change, and the slopes of curves, while integral calculus deals with the accumulation of quantities, and areas under or between curves.

Answer:

[tex]2x^{2}[/tex]+5x+9

Step-by-step explanation:

The difference of the given expression is 8x²-5x-9.

The given expressions are -3x²+5x-9 and 2x²+3(x²-6).

To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.

Now, subtract -3x²+5x-9 from 2x²+3(x²-6)

2x²+3(x²-6)-(-3x²+5x-9)

= 2x²+3x²-18+3x²-5x+9

= 8x²-5x-9

Hence, the difference of the given expression is 8x²-5x-9.

Greetings from Brasil...

According to the statement of the question, we can assemble the following equation:

9 + 6X = 3

6X = - 6

Answer:

AB=14

Step-by-step explanation:

First you write the equation 2(2x-4)=28 because if b is the midpoint then AB is half of the line so you multiply that half by two the make it equal to the whole line.

Then you distribute the two and get 4x-8=28.

Then you add 8 to 28 and get 36.

Then you divide 36 by 4 because the 4 and x are being multiplied together so you have to divide to get them apart.

So then you get x=9 and you aren't done yet because you have to plug x into 2x-4.

So it is 2(9)-4 which is 18-4 which equals 14.

There is no solution for system of equations:  [tex]a_1x+b_1y=c_1\\a_2y+b_2y=c_2[/tex]

if:     [tex]a_1=a_2\quad and\quad b_1=b_2\quad and\quad \bold{c_1\ne c_2}[/tex]

so first, we we need to transform the equations to the form where the coefficients at y will be the same:
