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.
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

lol
Answer:
x=-5 Hope this helped! Goodnight!
Step-by-step explanation:
Let's solve your equation step-by-step.
−3(2x+6)=12
Step 1: Simplify both sides of the equation.
−3(2x+6)=12
(−3)(2x)+(−3)(6)=12(Distribute)
−6x+−18=12
−6x−18=12
Step 2: Add 18 to both sides.
−6x−18+18=12+18
−6x=30
Step 3: Divide both sides by -6.
−6x /−6 = 30 /−6
x=-5
Answer:
x= -5

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.

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.

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
angle3=7=32 degrees
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.

Choose 1 answer: Choose 1 answer: (Choice A) A Ioana used an invalid reason to justify the congruence of a pair of sides or angles. (Choice B) B Ioana only established some of the necessary conditions for a congruence criterion. (Choice C) C Ioana established all necessary conditions, but then used an inappropriate congruence criterion. (Choice D) D Ioana used a criterion that does not guarantee congruence.
Answer:
The answer is Choice C
Step-by-step explanation:
I got it right, look at the screenshot for proof
Answer:
Choice C
Step-by-step explanation:
Writing a proof
A proof is a formal description of how we can know that something is true based on the information from a mathematical scenario.
Each step of the proof is a transformation, a construction, or a statement about what we can conclude from earlier steps.
For a two-column proof we give a reason to justify each statement. Common reasons include geometric theorems, algebraic properties, and information given in diagrams.
Let's check the reason for each step and whether Ioana established the conditions for it.
Hint #22 / 4
Step 1
The diagram does support the claim that PQ=RQ=9PQ=RQ=9P, Q, equals, R, Q, equals, 9.
Step 1 is correct.
Step 2
The diagram does support the claim that m\angle O=m\angle S=90\degreem∠O=m∠S=90°m, angle, O, equals, m, angle, S, equals, 90, degree.
Step 2 is correct.
Step 3
The diagram does support the claim that m\angle PQO=m\angle RQS=63\degreem∠PQO=m∠RQS=63°m, angle, P, Q, O, equals, m, angle, R, Q, S, equals, 63, degree.
Step 3 is correct.
Hint #33 / 4
Step 4
In this step, Ioana claims that \triangle OPQ\cong \triangle SRQ△OPQ≅△SRQtriangle, O, P, Q, \cong, triangle, S, R, Q using the angle-side-angle criterion. But the corresponding pair of congruent sides, \overline{PQ}
PQ
start overline, P, Q, end overline and \overline{RQ}
RQ
start overline, R, Q, end overline, aren't the sides that are included between the two pairs of congruent corresponding angles.
Ioana should have used the angle-angle-side criterion.
Hint #44 / 4
Ioana established all necessary conditions, but then used an inappropriate congruence criterion.

Statistic because the value is a numerical measurement describing a characteristic of a population. D. Parameter because the value is a numerical measurement describing a characteristic of a population.
Answer: A. Statistic because the value is a numerical measurement describing a characteristic of a sample.
Step-by-step explanation: Statistic are used to describe values obtained from a data sample which are regarded as a subset of the data belonging to an entire population. Therefore, in statistical parlance, numerical measurement obtained from such dataset are called statistic. On the other hand, if data from which a numerical derivation was made is a population which consists of the entire set of observations belonging to a particular group of interest, then the numerical values obtained are referred to as a parameter.
Given: The value [tex]65[/tex]% is a statistic.
