Answer:
Step-by-step explanation:
Length of the bridge = 190 m = 190*100 = 19000 cm {100cm = 1m}
Length of each pace of Robert = 80 cm
Minimum number of full paces = 19000/80
= 237.5
= 238 {because full paces}

Can a parallelogram have more than 3 lines of symmetry?
Answer:
no
Step-by-step explanation:
Parallelograms have zero lines of symmetry because it is impossible to draw a line through the center of any parallelogram that divides the figure into two equal halves that are mirror images of each other.
Answer:
Technical answer no
BUT
if you are in a college/postgraduate level group theory class yes
Step-by-step explanation:
Imagine a square, and imagine 4 lines across the top, the side, and the two diagonal ones. Because the two diagonal lines of symmetry are technically the same, there are only three possible lines.
if you are in the group theory class, comment and ill give a lengthy answer on that.

Answer:
D) 9:20 am
Step-by-step explanation:
Train A's route = 20 mins
Train B's route = 80 mins
80 ÷ 20 = 4
Therefore, Train B's route is 4 times the length of Train A's route.
Therefore, the time Train A and B will leave the station at the same time will be the first time Train B leaves after 8am.
1 hour = 60 minutes
8am + 80 minutes = 8am + 1 hr + 20 minutes = 9:20 am

The image represents a rectangular patio that has a length equal to 4 feet more than the width. What is the perimeter of the patio?
Answer:
4w+8 feet
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of its sides. Since opposite sides are identical in length, it can be computed as double the sum of adjacent side lengths. Here, the lengths are in feet.
P = 2(L+W)
P = 2((w+4) +w)
P = 4w +8
The perimeter of the patio is 4w+8 feet.

A triangle has one side measuring 16 inches and two sides measuring 13 inches. Is this triangle scalene?
yes
no
No, because a scalene triangle has to have all sides that are different lengths. 2 sides being 13 inches would mean that the triangle has 2 sides that are equal, making it an isosceles triangle.
Answer:
no
Step-by-step explanation:
A triangle is scalene when its sides have three different lengths. Your triangle has two sides with the same measure, so it is isosceles, not scalene.
At a pizza place, a large pizza cost $7.50 and toppings cost $0.50 each. Write an equation the can be used to represent the cost of a pizza, y, which x toppings.
Answer:

Answer:
10
Step-by-step explanation:
You just gotta do 120/12 which is 10
Can anyone help me with this please
Answer:
A. The solution to a system of equations is when the values of x are the same for both equations and if the y-values also match. With this being said, if x and y are the same in both equations, then that is the solution of the system of equations. We can use the table to find when x and y are equal in both equations to find the solution

Factor: 12x^2 + 14x + 12 = 18
Show work
Answer:
2(3x -1)(2x +3) = 0
Step-by-step explanation:
A graphing calculator can often provide useful help in discovering the real factors of polynomials.
We presume you want to factor the standard form equation ...
12x^2 +14x -6 = 0 . . . . . subtract 18 from both sides
2(6x^2 +7x -3) = 0 . . . . factor out the common factor
2(6x^2 +9x -2x -3) = 0 . . . . split the middle term to aid factoring
2(3x(2x +3) -1(2x +3)) = 0 . . . . factor pairs of terms
2(3x -1)(2x +3) = 0 . . . . . factored standard form equation
_____
Additional comments
The calculator graph shows the zeros are rational and have values -3/2 and 1/3. A zero of x=p means (x -p) is a factor. Translated to factors without fractions, these would be ...
(x +3/2) ⇒ (2x +3) and (x -1/3) ⇒ (3x -1)
The only remaining job is to find the additional factor that makes the leading coefficient be 12 instead of (2)(3) = 6.
__
When factoring 6x^2 +7x -3, we're looking for two numbers that have a sum of +7 and a product of (6)(-3) = -18. The factors we need are 9 and -2, which are the values we use when we split the middle term: 7x ⇒ 9x -2x.
We choose to do the factoring this way because it is straightforward and relatively easy to explain. There are other methods used when the leading coefficient is not 1, but they can be more difficult to explain.
Find cos (B) in the triangle
We can identify the sides of a right triangle by describing their location in relation to a given angle.
The "hypotenuse" is the longest side of a right triangle. It is opposite the right angle.The "opposite" is the side that the angle does not touch.The "adjacent" is the side that the angle does touch, that is not the hypotenuse.There are three basic trigonometric ratios:
The sine ratio: [tex]\sin\theta=\dfrac{opposite}{hypotenuse}[/tex]The cosine ratio: [tex]\cos\theta=\dfrac{adjacent}{hypotenuse}[/tex]The tangent ratio: [tex]\tan\theta=\dfrac{opposite}{adjacent}[/tex]We use theta (θ) to represent an angle.
Solving the QuestionWe are asked to find [tex]\cos(\beta)[/tex] in the triangle.
[tex]\cos\theta=\dfrac{adjacent}{hypotenuse}[/tex]
The side adjacent to β measures 8 units.
The hypotenuse of the right triangle measures 17 units.
[tex]\cos\beta=\dfrac{8}{17}[/tex]
AnswerTherefore, [tex]\cos\beta=\dfrac{8}{17}[/tex].

If two opposite sides of a square are increased by 15 meters and the other sides are decreased by 13 meters, the area of the rectangle that is formed is 60 square meters. find the area of the original square.
Answer: Shown below
Step-by-step explanation:
Since it's a square, we will refer to its values as x. Using that, we can make an equation for the rectangle.
(x + 15) * ( x - 13) = 60
We can expand it and simplify so that we get a zero on one side and a polynomial on the other.
(x + 15)(x - 13) - 60 = 0
x² + 2x - 225 = 0
We simplify the binomial so we get two answers for x.
(x - 15)(x + 17) = 0
x = 15 and -17
Now we have two answers. So which one is right? Well, the sides cannot be negative, therefore we must use 15 and not -17.
15² = 225
Our answer is 225
