A 4 cylinder engine with 543 cubic centimeters has what approximate displacement.
543 cubic centimeters has 0.543 L approximate displacement
Engine displacement means the displacement of the piston inside cylinder from Bottom Dead Center into Top Dead Center in one cycle.
Basic formula to calculate engine displacement is
V = π/4 x [tex]D^{2}[/tex] x H x N
Where :
D = Bore Diameter
H = Length of Stroke
N = Number of Cylinder
Since the question has already stated cubic centimeter, it has already show the displacement. So, we can ignore above formula and the 4 cylinder engine information.
First, we state what is known. It is the displacement at cubic centimeter
Cubic centimeter = 543 cc
Next, we change the unit of cubic centimeter ( cc ) into liter ( L )
Displacement = cc / 1000 L
= 543 / 1000 L = 0.543 L

Trisha and Byron are washing and vacuuming cars to raise money for a class trip. Trisha raised $38 by washing
5 cars and vacuuming 4 cars. Byron raised $28 by washing 4 cars and vacuuming 2 cars. Find the amount they
charged to wash a car and vacuum a car.
Answer:
Step-by-step explanation:
Let x = amount charged for washing a car
y = amount charged for vacuuming a car
Solution :38 = 5x + 4y (1)
28 = 4x + 2y (2)
Can be solved by substitution or simply subtracting the (1) and (2) equation.
By Substitution:
38 = 5x + 4y ---> solve for x
38 - 4y = 5x (transposed 4y to the other side of the equation and it's sign changes from (+) to (-).
[tex]\frac{38-4y}{5} =x[/tex]
substitute the value of x to the (2) equation.
28 = 4x + 2 y
[tex]28=4(\frac{38-4y}{5})+2y[/tex]
[tex]28=\frac{152-16y}{5} +2y[/tex] , then multiply both side by 5 to eliminate the denominator 5.
140 = 152 - 16y + 10y (transposed 152 to the other side, change sign from (+) to (-)).
140 - 152 = -16y + 10 y
-12 = -6y (divide both side by (-6)
y = 2 or $2 (amount charged for vacuuming)
Using any of the 2 equation, we can solve for the value of x.
38 = 5x + 4 (2) (we substitute, the value of y)
38 - 8 = 5x
30/5 = x
x= 6 or $6 (amount charged for washing)

Circle constructions are used in many fields such as geometry, engineering, and architecture to create precise circles. It's a fundamental concept in mathematics, and it's important to understand how to construct circles to apply these concepts in different fields.
His next step would be to draw a circle with a center F and a radius equal to BG.
By creating a circle with a center F and a radius equal to BG, He is creating a congruent circle to the original circle A with the center A, and radius AB.
The point of intersection between circle D and ray DE would also be an important step as it would give the location of the new angle. The point of intersection between circle D and circle A would also be an important step as it would confirm that the two circles are congruent.
Drawing ray DE away from angle BAC is also an important step, as it would create a new angle with the same properties as angle BAC.

How do you dilate a triangle with a scale factor of 2 3?
The basic formula to find the scale factor of a dilated figure is: Scale factor = Dimension of the new shape ÷ Dimension of the original shape.The dilation o a triangle with a scale factor of 2 3 represents a contraction.
How to Dilate a triangle with a scale factor ?
The scale factor is defined as the proportion of the new image's size to that of the previous image. A fixed location in the plane serves as the centre of dilatation. The scale factor and the centre of dilation are used to determine the dilation transformation.
The image stretches if the scaling factor is greater than 1.The image contracts if the scale factor is between 0 and 1.The original image and the resulting image are consistent if the scale factor is 1.Finding the dilation's centre point is the first step in determining the scale factor. Next, we measure the distances between the centre point and various points on the preimage and the image. According to Math Bits Notebook, the scale factor is equal to the ratio of these distances.
Since each angle is congruent, every segment is proportional, the slope of every segment is preserved, and the perimeter of the preimage and image have the same scale factor, we may use dilation scale factors to compress or enlarge a figure to the size we desire.

The ratio of the measures of the three angles in a triangle is 14:5:11. Find the measures of the angles.
The smallest angle =
The medium angle =
The largest angle =
Answer:
See below
Step-by-step explanation:
All of the interior angles of a triangle sum to 180 °
Smallest is 5 out of (14 + 5 + 11) = 5/30 ths of 180° = 30°
Middle is 11/30 ths = 66°
Largest is 14/30 ths = 84°
Answer:
30° , 66° , 84°
Step-by-step explanation:
sum the parts of the ratio, 14 + 5 + 11 = 30 parts
divide the sum of the angles in a triangle 180° by 30 to find the value of one part of the ratio.
180° ÷ 30 = 6° ← value of 1 part of the ratio , then
smallest angle = 5 × 6° = 30°
medium angle = 11 × 6° = 66°
largest angle = 14 × 6° = 84°
