Which expression is equivalent to 3/8 + 4/8

Answer:

It will take 8 hours to go 64 miles.

Step-by-step explanation:

x / y = z

x = 64 (Miles you need to go.)

y = 8 ( Miles per hour.)

z = How long it will take.

64/8 = z

64/8 = 8

It will take 8 hours to go 64 miles.

Answer:

The product of two rational numbers is rational, and the sum of two rational numbers is irrational.

Step-by-step explanation:

Let be [tex]a[/tex] and [tex]b[/tex] rational numbers whose forms are, respectively:

[tex]a = \frac{m}{n}[/tex] and [tex]b = \frac{q}{r}[/tex], [tex]m[/tex], [tex]n[/tex], [tex]q[/tex], [tex]r[/tex] [tex]\in \mathbb{Z}[/tex]

We proceed to demonstrate if the Pythagorean sum of two rational numbers leads to a rational number.

1) [tex]a = \frac{m}{n}[/tex],  [tex]b = \frac{q}{r}[/tex], [tex]m[/tex], [tex]n[/tex], [tex]q[/tex], [tex]r[/tex] [tex]\in \mathbb{Z}[/tex] Given.

2) [tex]c^{2} = a^{2}+b^{2}[/tex] Given.

3) [tex]c^{2} = \left(\frac{m}{n} \right)^{2}+\left(\frac{q}{r} \right)^{2}[/tex] 1) in 2)

4) [tex]c^{2} = (m\cdot n^{-1})^{2}+(q\cdot r^{-1})^{2}[/tex] Definition of division.

5) [tex]c^{2} = [m^{2}\cdot (n^{-1})^{2}]+[q^{2}\cdot (r^{-1})^{2}][/tex]    [tex](a\cdot b)^{c} = a^{c}\cdot b^{c}[/tex]

6) [tex]c^{2} = m^{2}\cdot n^{-2}+q^{2}\cdot r^{-2}[/tex]   [tex](a^{b})^{c} = a^{b\cdot c}[/tex]

7) [tex]c^{2} = [m^{2}\cdot (n^{2})^{-1}]+[q^{2}\cdot (r^{2})^{-1}][/tex]  [tex](a^{b})^{c} = a^{b\cdot c}[/tex]

8) [tex]c^{2} = \frac{m^{2}}{n^{2}}+\frac{q^{2}}{r^{2}}[/tex] Definition of division.

9) [tex]c^{2} = \frac{m^{2}\cdot r^{2}+q^{2}\cdot n^{2}}{n^{2}\cdot r^{2}}[/tex]  [tex]\frac{x}{y} +\frac{w}{z} = \frac{x\cdot z+w\cdot y}{y\cdot z}[/tex]

10) [tex]c^{2} = \frac{(m\cdot r)^{2}+(q\cdot n)^{2}}{(n\cdot r)^{n}}[/tex]    [tex](a\cdot b)^{c} = a^{c}\cdot b^{c}[/tex]/Result.

If [tex]c[/tex] is a rational number, then [tex](m\cdot r)^{2}+(q\cdot n)^{2} = a^{2}[/tex], so that [tex]a \in \mathbb{Z}[/tex]. Which means that [tex]c[/tex] will be rational number if and only if the square root of [tex](m\cdot r)^{2}+(q\cdot n)^{2}[/tex] is an entire number.

Which means that correct answer is B.

3. -3= (5/2)(2) + b

4. -8

5. y= (5/2)x - 8

Step-by-step explanation:

The slope of the graphed line is 5/2

The slope of the parallel line is 5/2

An equation that can be used to find the y-intercept of the parallel line is -3=(5/2)(2) + b

The y-intercept of the parallel line is -8

The equation of the parallel line is y= (5/2)x - 8

Answer:

The width of the spotlight is  20 inches

Step-by-step explanation:

The location of the bulb = 2.5 inches above the vertex

The height of the spotlight = 10 inches

The width of the spotlight =

The

The height of

The equation of a parabola is given as follows;

(x - h)² = 4p(y - k)

Focus, (h, k + p) = (0, 2.5)

y = k - p

k  + p = 2.5

Vertex = (h, k) = (0, 0), therefore, k = 0

p = 2.5

We have;

(x - 0)² = 4p(y - 0)

x² = 4×2.5 × y = 10·y

Therefore, given that y = 10, we have;

x² = 10 × 10 = 100

x = √100 = ±10

The coordinates of the two end points are;

(-10, 10), and (10, 10)

Therefore, the width of the spotlight = the distance between the end points  

Given that the y-values are the same, we have

Distance = 10 - (-10) = 10 + 10 = 20 inches

∴ The width of the spotlight =  20 inches.

Answer:

140%

Step-by-step explanation:

Percentage change in any variable is given by

percentage change = (new value - old value)/ old value * 100

_________________________________________________

Given

Earlier amount of drinking water = 20 fl oz

New amount of drinking water = 48 fl oz

Percentage increase in drinking of water = (48-20)/20 * 100 = 28/20 * 100

Percentage increase in drinking of water =  28*5 = 140 %

Thus, there is 140% percentage increase in water by John.

Answer:

x = 1

Step-by-step explanation:

–4(2x−2)= –(4x−4)

-8x-(-8) = -4x-(-4)

-8x+8 = -4x+4

-8x+8-8 = -4x+4-8

-8x = -4x+(-4)

-8x+4x = -4x+4x+(-4)

-4x = -4

-4x/-4 = -4/-4

x = 1

Answer: True.

Step-by-step explanation:

The statement is:

"A linear equation has ONE solution when the variable equals zero."

First, a generic linear equation can be written as:

y = a*x + b

Where a and b are known values.

If the variable equals zero, we have:

y = a*0 + b = b

y = b.

Then it has only one solution if x = 0.

So the statement is true, but it is also true for any value in the variable.

So if we rewrite it as (for example):

"A linear equation has one solution when the variable equals 4"

y = a*4 + b.

Because a and b are known, this equation also does have only one solution.

Answer:

148

Step-by-step explanation:

angle 1=3

angle3=7=32 degrees

angle6+angle7= 180

angle 6=180-32

angle 6= 148 degrees

The measure of m<6 is 148.

Properties of Parallel Lines

Parallel lines are the set of lines that lie on the same plane but never intersect each other, even if you extend them infinitely.

Given:

m∠1=32°

Now, using vertical opposite angle

m<1 = m<3 = 32

Now, using same- side interior transversal

m<3 + m<6 = 180

32 + m<6 = 180

m<6 = 180-32

m<6 = 148

Hence, the measure of angle 6 is 148.
