A speed walker covered 4 1/2 mi in 3/4 hour. How far will he walk in 3/4 hours if he walks twice as fast?
PLS HELP ASAP
Answer: 9 miles
Step-by-step explanation:
The distance would be 9 because if the speed walker walked 4.5 miles in 3/4 of an hour, he would be going 6 mph (miles per hour).
If he walks twice as fast, he would be going 12 mph.
If he walks for 3/4 of an hour (45 minutes) at 12 mph, he would walk 9 miles.
9 miles he walks in 3/4 hours if he walks twice as fast.
What is speed?Speed is characterized as the pace of progress of the position of an item toward any path. Speed is estimated as the balance of length to the time in which the distance was covered. Speed is a scalar amount as it has just course and no size.
4 1/2 miles will be covered by him in 3/4 hour
if the speed walker covered 4.5 miles in just over an hour
The duration would indeed be 9 since the speed walker might be moving at a rate of six miles per hour.
He would be moving at 12 miles per hour if he walked twice as quickly.
He would cover 9 miles in 3/4 of an hour (45 minutes) of walking at a speed of 12 miles per hour.

The image point of A after a translation left 3 units and down 1 unit is the point
B(-8, -2). Determine the coordinates of the pre-image point A.
Answer:
b
Step-by-step explanation:
There is no answer or document
The coordinates of the pre-image of point A are (-5, -1).
What is the difference between upward, downward, leftwards and rightwards translation?Upward translation = [k] units
When the upward translation take's place then, each point will have its y - coordinate shifted upwards by +k units.
Downward translation = [k] units
When the downward translation will take place then, each point will have its y - coordinate shifted downwards by -k units.
Leftward Translation = [k] units
When the leftward translation will take place then, each point will have its x - coordinate shifted by -k units to the left.
Rightward Translation = [k] units
When the rightward translation will take place then, each point will have its x - coordinate shifted by +k units to the right
We have the image of point [A] after a translation left by 3 units and down by 1 unit is the point B(-8, -2).
Assume that the original coordinates are -
(x, y)
Then, we can write -
(x - 3, y - 1) = (-8, -2)
x - 3 = - 8
y - 1 = -2
x = - 5
y = - 1
Therefore, the coordinates of the pre-image of point A are (-5, -1).

find the distance between the points (-3,10) and (9,-6)
Answer:
20
Step-by-step explanation:
The distance formula is:
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
where (x₁, y₁) and (x₂, y₂) are the points. We are given the points (-3,10) and (9,-6). Therefore,
[tex]x_{1}=-3 \\y_{1}= 10\\x_{2}=9 \\y_{2}=-6[/tex]
Substitute the values into the formula.
[tex]d = \sqrt {\left( {-3 - 9} \right)^2 + \left( {10- -6} \right)^2 }[/tex]
[tex]d = \sqrt {\left( {-3 - 9} \right)^2 + \left( {10+6} \right)^2 }[/tex]
Solve inside the parentheses. Subtract 9 from 3. Add 10 and 6.
[tex]d = \sqrt {\left( {-12} \right)^2 + \left( {16} \right)^2 }[/tex]
Evaluate the exponents.
⇒ -12²= -12*-12= 144
[tex]d = \sqrt {\left144 + \left( {16} \right)^2 }[/tex]
⇒ 16²= 16*16=256
[tex]d = \sqrt {\left144 + \left256}[/tex]
Add 144 and 256.
[tex]d=\sqrt{400}[/tex]
Take the square root of 400.
[tex]d=20[/tex]

WILL NAME BRAINLIEST WHOEVER CAN HELP ME FIRST! PLEASE I NEED A REAL ANSWER!! A quadrilateral is graphed on a coordinate plane. If the vertices are A(2, 6), B(6, 0), C(2, –6) and D(–4, 0), which two points are farthest apart? A. A and B B. B and D C. A and C D. C and D
Answer:
A(2, 6) and C(2, -6)
Step-by-step explanation:
The distance between any two points is given by :
Given vertices : A(2, 6), B(6, 0), C(2, -6) and D(-4, 0)
Since, points A and C has the largest distance between them.
Therefore, the points A and C are the farthest points.

Simplify (5x−2+3x^2)+(4x+3)
Answer:
3x^2 + 9x + 1
Or
3x ( x + 3 ) + 1
Step-by-step explanation:
(5x - 2 +3x^2 ) + (4x + 3 )
To make this a little bit more easier to read, you can remove the parentheses:
5x - 2 + 3x^2 + 4x + 3
Now, write in a way so that the like terms are next to each other:
3x^2 + 5x + 4x - 2 + 3
Now simplify the 'x' terms to get:
3x^2 + 9x - 2 + 3
Now, simplify the integers (the ones with now variables with them) to get:
3x^2 + 9x + 1
If you want, you can factor out the 3x for two of the terms to get :
3x ( x + 3 ) + 1
Therefore, your simplest form can either be 3x^2 + 9x + 1 OR 3x (x + 3 ) + 1

True or false Exterior angles are the angles created when the sides of the triangle are shortened.
This statement is true.
This statement is false. Exterior angles are pairs of angles whose measures add up to 360
This statement is false. Exterior angles are the angles inside the triangle
This statement is false. Exterior angles are the angles created when the sides of the triangle are extended.
Answer:
The statement is false. Exterior angles are the angles created when the sides of the triangle are extended
Step-by-step explanation:
In order to find the exterior angle of a polygon, the side of the polygon is extended to go past the vertex of the polygon to form an angle adjacent and supplementary to the the interior angle of the polygon at the vertex of the polygon where the exterior angle is formed.
The sum of the exterior angle and the adjacent interior angle is equal to 180°
The exterior angle can also be described as being formed by one side of a polygon and an extension of the adjacent side to previous side of the same polygon and it can also be referred to as a turning or an external angle.

Work out the area of the circle.
Answer:
Side of square=Diameter of circle=16
Radius= Diameter/2=16/2=8
Area of circle=4Πr²
=4*3.14*8²
=803.84cm²
The area of the circle that is formed inside the square will be 200.96 square cm.
What is the area of the circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The length of the square is 16 cm.
From the diagram, the length of the square is equal to twice the radius of the circle. Then we have
2r = a
2r = 16
r = 8 cm
The area of the circle is given as,
A = π (8)²
A = 3.14 × 64
A = 200.96 square centimeters
The region of the circle that is framed inside the square will be 200.96 square cm.
