615 mph
Step-by-step explanation:
5 times 3 is 15
3,075 times 3 is 9,225
So 9,225 divided by 15 equals 615
John increased the amount of water he drinks everyday from 20 fl oz to 48 fl oz. By what percent did John increased the water he drinks?
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.

The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the
hypotenuse by the formula a2 + b2 = c2.
If a is a rational number and b is a rational number, why could c be an irrational number?
O The square of rational numbers is irrational, and sum of two irrational numbers is irrational.
O The product of two rational numbers is rational, and the sum of two rational numbers is irrational.
O The left side of the equation will result in a rational number, which is a perfect square.
O The left side of the equation will result in a rational number, which could be a non-perfect square.
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.
–4(2x−2)= –(4x−4) what is x?
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
Item 7 A parabolic spotlight is being designed with the lightbulb at the focus point. If the lightbulb is placed 2.5 inches above the vertex and the height of the spotlight is 10 inches, what is the width of the spotlight? Item 7 A parabolic spotlight is being designed with the lightbulb at the focus point. If the lightbulb is placed 2.5 inches above the vertex and the height of the spotlight is 10 inches, what is the width of the spotlight?
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.

How long will it take Pablo to bike 64 miles if he is biking at a speed of 8 mph?
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.

In the following figure (AB) ∥(CD). Suppose that m∠1=32°. What is m∠6? Explain your reasoning
Answer:
148
Step-by-step explanation:
angle 1=3

angle6+angle7= 180
angle 6=180-32
angle 6= 148 degrees
The measure of m<6 is 148.
What are properties of parallel lines?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.
The pairs of corresponding angles are equal.The pairs of vertically opposite angles are equal.The pairs of alternate interior angles are equal.The pairs of alternate exterior angles are equal.The pair of interior angles on the same side of the transversal is supplementary.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.

A linear equation has ONE solution when the variable equals zero. Explain if this is a true or false statement and why?
GET BRAINLYY EXPLAIN
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:true
