Answer:

25h = x

Step-by-step explanation:

If x is the variable for how many pages she reads in total, 25 multiplied by h (the number of hours) will give you the total pages read!

Step-by-step explanation:

v = 1/3bh

3v/b = h

Answer:

t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t = -q_1/h - sqrt((2 z)/h + ((q_1)^2)/(h^2))

Step-by-step explanation:

Solve for t:

z = (h t^2)/2 + t q_1

z = (h t^2)/2 + t q_1 is equivalent to (h t^2)/2 + t q_1 = z:

(h t^2)/2 + t q_1 = z

Divide both sides by h/2:

t^2 + (2 t q_1)/h = (2 z)/h

Add q_1^2/h^2 to both sides:

t^2 + (2 t q_1)/h + q_1^2/h^2 = (2 z)/h + q_1^2/h^2

Write the left hand side as a square:

(t + q_1/h)^2 = (2 z)/h + q_1^2/h^2

Take the square root of both sides:

t + q_1/h = sqrt((2 z)/h + q_1^2/h^2) or t + q_1/h = -sqrt((2 z)/h + q_1^2/h^2)

Subtract q_1/h from both sides:

t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t + q_1/h = -sqrt((2 z)/h + q_1^2/h^2)

Subtract q_1/h from both sides:

Answer: t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t = -q_1/h - sqrt((2 z)/h + ((q_1)^2)/(h^2))

Answer: The equation for the perpendicular bisector of line segment xy is .

Explanation:

It is given that the line segment xy has endpoints x(5,7) and y(-3,3).

The bisector divides the line segment xy in two equal parts, so the bisector must be passing through the midpoint of xy.

Midpoint of two points (x_1,y_1) and (x_2,y_2) is calculated as,

Midpoint of xy is,

So, the perpendicular bisector must be passing through the point (1,5).

The slope of line passing through the point (x_1,y_1) and (x_2,y_2) is calculated as,

Slope of line segment is . Therefore the slope of perpendicular bisector is -2 because the the product of slopes of two perpendicular lines is always -1.

The line passing through the point (x_1,y_1) with slope m is defined as,

Bisector passing through the point (1,5) with slope 2.

Therefore, the equation for the perpendicular bisector of line segment xy is .

:D have a nice day

it is less than square root 30

Answer:

Step-by-step explanation:

Since the perimeter is 46, and opposite sides of a rectangle are equal, we know that

(x+2)+(x+2)+(2x+3)+(2x+3)=46

Combine like terms to get: 6x+10=46

Subtract 10 from both sides to get: 6x=36

Divide both sides by 6 to get: x=6.

Answer:

Lets start off by clearing up the question,

I'm assuming it's asking m(x) * n(x). Doing so will make you foil it, giving you a quadratic/ polynomial.

Because it is a polynomial, we can assume all real numbers are defined. So really any poly works.

Edit: To clarify, you can make any quadratic equation and it will have the same domain as any polynomial is defined. So for example: x^2 + 2x + 5 works.

Step-by-step explanation:

Using the Pythagorean's theorem,

DO²=DG²+GO²=3²+3²=2*3²

DO=3√2

JO=DO-DJ=3√2-3=3(√2-1)

[tex]120=2^3 \times 3 \times 5[/tex]

Answer:

2³ × 3 × 5

Step-by-step explanation:

To find the prime factors, first divide 120 by 2 until finished , then 3 and so on

120 ÷ 2 = 60

60 ÷ 2 = 30

30 ÷ 2 = 15

15 ÷ 3 = 5

5 ÷ 5 = 1 ← finish when 1 is obtained

Then

120 = 2× 2 × 2 × 3 × 5 = 2³ × 3 × 5

Step-by-step explanation:

the sum of all angles in a triangle is 180 degrees.

so,

x + (x - 6) + (2x + 34) = 180

x + x - 6 + 2x + 34 = 180

4x + 28 = 180

4x = 152

x = 38 degrees

x - 6 = 32 degrees

2x + 34 = 110 degrees

Math books= 2/15

Answer:

x = 2

Step-by-step explanation:

The volume (V) of a cuboid is calculated as

V = lbh ( l is length, b is breadth, h is height )

Here l = 10x , b = [tex]\frac{7}{4}[/tex] , h = 2 , then

V = 10x × [tex]\frac{7}{4}[/tex] × 2 = 70 , that is

20x × [tex]\frac{7}{4}[/tex] = 70

5x × 7 = 70

35x = 70 ( divide both sides by 35 )

x = 2

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

Since L × W × H = V, we get

[tex]10x*\frac{7}{4}*2=70\\10x*\frac{7}{4}=35\\10x=20\\x=2[/tex]
