Vincent made a sketch that measures 10 inches by 15 inches. If he creates a new drawing where each of the dimensions is tripled, what will be the perimeter of the new drawing?
Answer:
150 inches
Step-by-step explanation:
Vincent sketch is a rectangle
10 inches by 15 inches
Length=15 inches
Width=10 inches
If each dimension is tripled
Then,
Length=15*3=45
Width=10*3=30
Perimeter of the new drawing=2(length+width)
=2(45+30)
=2(75)
=150 inches

Given the following system of equations:
3x + 5y = 30
X + 3y = 10
Which action creates an equivalent system that will eliminate one variable when they are combined?
Answer:
multiply second equation by (-3)
new system of equations:
3x + 5y = 30
-3x - 9y = -30
Step-by-step explanation:
x + 3y = 10
multiplied by (-3):
-3x - 9y = -30
combinig:
3x+5y + (-3x-9y) = 3x - 3x + 5y - 9y = -4y
10 + (-30) = -20
so: -4y = -20
Answer:
Multiply the second equation by −3 to get −3x − 9y = −30.

Instructions: Find the equation of the line through point (5, 1) and
perpendicular to 5x - y = -3. Use a forward slash (i.e. "/") for fractions
(e.g. 1/2 for).
make y the subject
y= 5x + 3
perpendicular line needs the reciprocal of the gradient
y = 1/5x + c
substitute in the point
1 = 1/5(5) + c
5/5 = 1 so the answer is y = 1/5x
hope this is helpful!
The required equation of the line is [tex]\bold{y=-\frac{1}{5}x+2}[/tex]
What is the slope-point form of equation of the line?"The equation of the line having slope m and passing through points (p, q) is (y - q) = m(x - p)"
What is the slope-intercept form of the line?"y = mx + c, where m is the slope and c is the Y-intercept of the line."
For given question,
We have been given a point (5, 1)
The required line is perpendicular to the line 5x - y = -3
⇒ 5x - y = -3
⇒ - y = -5x - 3
⇒ y = 5x + 3
Comparing above equation with slop-intercept form of the line.
m = 5
Let m1 be the slope of the required line.
We know that the product of the slopes of perpendicular lines is -1.
⇒ m1 × m = -1
⇒ m1 = [tex]\frac{-1}{5}[/tex]
Now we find the equation of the required line by using slope-point form.
Let (p, q) = (5, 1)
By using slope-point form,
⇒ (y - q) = m1(x - p)
⇒ (y - 1) = [tex]-\frac{1}{5}[/tex] (x - 5)
⇒ y - 1 = [tex]-\frac{1}{5}x[/tex] + 1
⇒ y = [tex]-\frac{1}{5}x[/tex] + 2
Therefore, the required equation of the line is [tex]\bold{y=-\frac{1}{5}x+2}[/tex]

Lucio quiere repartir su colección de estampillas entre la mayor cantidad de amigos pero de manera que todos reciban la misma cantidad tiene parar repartir 30 estampillas de animales 75 estampillas de flores y 160 de ciudades del mundo cuantos grupos iguales puede armar
Answer:
Lucio podrá armar 5 grupos iguales de estampillas.
Step-by-step explanation:
El problema plantea un caso de distribución mediante la aplicación del divisor común mayor a todos los números involucrados. Para ello, primero debemos analizar los divisores de cada uno de estos números:
-30: divisible por 2, 3, 5, 6, 10, 15 y 30.
-75: divisible por 3, 5, 15, 25 y 75.
-160: divisible por 2, 4, 5, 8, 10, 16, 20, 32, 40, 80 y 160.
Así, podemos ver que el divisor común mayor a los tres números es 5, ya que 30, 75 y 160 dan como resultado un número entero tras ser divididos por 5.
Entonces, para poder repartir equitativamente sus estampillas entre la mayor cantidad de amigos posibles, deberá repartir 6 estampillas de animales, 15 estampillas de flores y 32 estampillas de ciudades a 5 amigos. De esta manera, Lucio podrá armar 5 grupos iguales de estampillas.

They can leave tonight by bus, or they can save two hours by leaving tomorrow morning and using the express train which travels 20 km/h faster than the bus. If the distance between South Central High and Calgary is 800 km, determine how long it will take to travel by bus, rounded to the nearest hour.
Answer:
The bus will take 10 hours to travel from South Central High to Calgary.
Step-by-step explanation:
Let suppose that both bus and express train travels at constant speed, whose kinematic formula is now described:
[tex]v = \frac{\Delta s}{\Delta t}[/tex]
Where:
[tex]v[/tex] - Speed, measured in kilometers per hour.
[tex]\Delta s[/tex] - Travelled distance, measured in kilometers.
[tex]\Delta t[/tex] - Time, measured in hours.
The transportation time is cleared afterwards:
[tex]\Delta t = \frac{\Delta s}{v}[/tex]
The kinematic expressions for the bus and the express bus are, respectively: ([tex]\Delta s = 800\,km[/tex])
Bus
[tex]\Delta t = \frac{800\,km}{v}[/tex]
Express train
[tex]\Delta t - 2\,h = \frac{800\,km}{v + 20\,\frac{km}{h} }[/tex]
By eliminating [tex]\Delta t[/tex]:
[tex]\frac{800\,km}{v} -2\,h = \frac{800\,km}{v+20\,\frac{km}{h} }[/tex]
[tex]\frac{800\,km}{v} - \frac{800\,km}{v+20\,\frac{km}{h} } = 2\,h[/tex]
[tex]800\cdot (v+20)-800\cdot v = 2\cdot v\cdot (v+20)[/tex]
[tex]16000 = 2\cdot v^{2}+40\cdot v[/tex]
[tex]2\cdot v^{2}+40\cdot v -16000 = 0[/tex]
Which is a second-order polynomial and whose roots are:
[tex]v_{1} = 80\,\frac{km}{h}[/tex] and [tex]v_{2} = -100\,\frac{km}{h}[/tex]
Only first root is physically reasonable, as speed is a scalar, that is, a number that is represented only by magnitude. Then, the time taken by the bus to travel from Central High to Calgary is: ([tex]v = 80\,\frac{km}{h}[/tex])
[tex]\Delta t = \frac{800\,km}{80\,\frac{km}{h} }[/tex]
[tex]\Delta t = 10\,h[/tex]
The bus will take 10 hours to travel from South Central High to Calgary.

Answer:
Area = base x height
Step-by-step explanation:
8X11=88sq
Answer:
88 units^2
Step-by-step explanation:
The area of a parallelogram can be found using he following formula:
a=b*h
where b is the base and h is the height.
We know that 11 units is the base and 8 units is the height (forms a right angle with one of the bases).
b= 11 units
h= 8 units
Substitute these values into the formula.
a= 11 units * 8 units
Multiply
a= 88 units^2
The area of the parallelogram is 88 square units.

Triangle A"B"C" is formed using the translation (x+1, y+1) and the dilation by a scale factor of 3 from the origin. Which equation explains the relationship between BC and B"C"?
Answer:
(Option b): segment BC = segment B double prime C double prime over 3
A complete question related to this found at brainly (ID: 13432500) is stated below:
Triangle A″B″C″ is formed using the translation (x + 1, y + 1) and the dilation by a scale factor of 3 from the origin. Which equation explains the relationship between segment BC and segment B double prime C double prime? coordinate plane with triangle ABC at A negative 3 comma 3, B 1 comma negative 3, and C negative 3 comma negative 3
a) segment B double prime C double prime = segment BC over 3
b) segment BC = segment B double prime C double prime over 3
c) segment B double prime C double prime over segment BC = one third
d) segment BC over segment B double prime C double prime = 3
Step-by-step explanation:
Scale factor = 3
∆ABC = original image
∆ABC was dilated to get ∆A"B"C"
∆A"B"C" = new image
DO(x,y) →3(x,y)
To determine which equation explains the relationship between segment BC and segment B"C", first we would find the distance B and C.
Coordinates of ∆ABC
A =(-3, 3)
B= (1, -3)
C= (-3, -3)
The distance B and C = length of Segment BC
the distance between two points = √[(∆x)² + (∆y)²]
= √[(-3-(-3))² + (-3-1)²] = √[(-3+3)² + (-3-1)²]
= √(0+16) = √16 = 4
Length of Segment BC = 4 units
Length of Segment B"C" = scale factor × Length of Segment BC
B"C" = 3 × BC = 3(4) = 12
Since what we need is the equation of the relationship between the segments
B"C" = 3 × BC
BC = B"C"/3
(Option b): segment BC = segment B double prime C double prime over 3

write this set B={3,9,27,81} in set builder form
Answer: [tex]B=\{3^x:x\in N, x\leq4\}[/tex]
Step-by-step explanation:
Given set: [tex]B=\{3,9,27,81\}[/tex] which is in a rooster form.
A set-builder form is a mathematical form to representing a set by stating the properties that its elements must satisfy.
In the given set each element is a multiple of 3.
[tex]3=3^1\\9=3^2\\27=3^3\\81=3^4[/tex]
So, [tex]B=\{3^1, 3^2, 3^3, 3^4\}[/tex] ,where 1,2,3,4 are natural numbers
The set-builder notation would be :
[tex]B=\{3^x:x\in N, x\leq4\}[/tex], where N is the set of natural numbers.

Which phrase represents the algebraic expression 3p+6/7p-9
Answer:
The answer is the sum of three times a number and six, divided by the difference of seven times the number and nine
Step-by-step explanation:
3p = three x a number
7p = seven x a number
3p+6 = sum of three x a number plus six
7p-9 = difference of seven x the number minus nine
(3p+6)/(7p-9) = sum of three times x number plus six, divided by the difference of seven x the number - nine
Find the area of the shaded region. Use 3.14 for pi. Round to the nearest tenth.
r = 15
110
Answer:
110/360=11/36 (I will get back to this)
The area of the circle would be 225 pi using the formula pi r^2. So you multiply 225pi by 11/36 to find the area. This rounds to 215.98
Answer: 490.6
Step-by-step explanation:
There are 360 degrees of a triangle. As 110 degrees are not shaded, you can determine that 250/360, or 25/36 of the degrees in the triangle are shaded. Then simply find the area of the circle by doing πr^2 and getting 706.5. Then simply multiply 706.5 * 25/36 to get 490.625, or 490.6 when rounding to the nearest tenth

Answer:
EF corresponds to E'F'.
∠EDG Is-congruent-to ∠E'D'G'
∠DEF Is-congruent-to ∠D'E'F'
The transformation is a rigid transformation.
Step-by-step explanation:
Which statements are true regarding the transformation? Check all that apply.
EF corresponds to E'F'.
FG corresponds to G'D'.
∠EDG Is-congruent-to ∠E'D'G'
∠DEF Is-congruent-to ∠D'E'F'
The transformation is not isometric.
The transformation is a rigid transformation.
Answer: Transformation is the moving of the location of a point from one place to another. If an object is transformed, all the points of the object are also transformed. There are four types of transformation: reflection, dilation, rotation and translation.
Points DEFG is mapped to D’E’F’G, The corresponding lengths and angles of the parallelogram still remains the same, Therefore the following applies:
EF corresponds to E'F'.
∠EDG Is-congruent-to ∠E'D'G'
∠DEF Is-congruent-to ∠D'E'F'
FG does not corresponds to G'D' because their lengths are not corresponding but are adjacent.
The transformation is a rigid transformation. A rigid transformation (isometric) preserves the length of the object.
Answer:
EF corresponds to E'F'
<EDG=<E'D'G'
<DEF=D'E'F'
The transition is a rigid transformation
