Answer:
the ratio of this one is 0.2\1
Answer:
To calculate the ratio, we should have both quantities in same units, so we can convert the kilometer into meters, knowing that 1 kilometerr are 1000m.
1 * 1000 = 1000m
We know we need to calculate the ratio 200:1000.
We can know divide both quantities by 200 and get...
200/200:1000/200 = 1:5
And now,, we know this ratio is 1:5..

Answer:
These triangles cannot be proven congruent
Step-by-step explanation:
The 3 angles in ∆FGH are congruent to the 3 corresponding angles on ∆ABC.
These mean that the two triangles have the same shape and we can conclude that they are similar to each other.
However, knowing just the 3 angles is not enough to prove that both triangles are congruent to each other. This is because, for two triangles to be congruent to each other, all 3 angles and 3 sides of one triangle must be congruent to the corresponding 3 angles and 3 sides of the other. That is, they have the same shape and size.
Therefore, the triangles given above cannot be proven congruent.

If a right triangle has sides of length 3 and 6, what is the length of the hypotenuse?
Answer:
Length of the hypotenuse = 3√5 units
Step-by-step explanation:
Given:
Right triangle sides
a = 3
b = 6
Find:
Length of the hypotenuse
Computation:
Length of the hypotenuse = √a² + b²
Length of the hypotenuse = √3² + 6²
Length of the hypotenuse = √9 + 36
Length of the hypotenuse = √45
Length of the hypotenuse = 3√5 units
An 18 foot ladder rests against a wall. The base of the ladder is 8 feet from the wall. What angle does the
ladder make with the ground?
Answer:
The angle would be acute
Step-by-step explanation:
The angle that this ladder would make with the ground is equal to 63.64°.
How to determine the angle that the ladder make?In order to determine the angle that this ladder would make with the ground, we would apply Cosine trigonometric. Mathematically, this is given by this expression:
Cosθ = Adj/Hyp
Substituting the given parameters into the formula, we have;
Cosθ = 8/18
Cosθ = 0.4444
θ = cos⁻¹ (0.4444)
θ = 63.64°

Answer:
(a) Function f is a proportion, so its slope is y/x = 3. The slope of function g is the x-coefficient, 7. The slope of function g is greater. (b) A proportion has a y-intercept of 0; function g has a y-intercept of 2. The y-intercept of function g is greater.(a) The y-intercept is 665, the initial distance to destination. (b) The train's distance to destination is decreasing at 95 miles per hour. (c) The useful domain of the relation is 0 ≤ x ≤ 7.(a) Standard form equation: 5x -y = -4. (We expect that "slope-intercept" form is desired: y=5x+4.) (b) f(x) = 5x +4. (c) The line can be graphed by starting at the y-intercept (0, 4) and drawing a line with slope 5. Axes will be labeled "Rental Time (hours)" (horizontal) and "Rental Cost (dollars)" (vertical). Axes can be numbered in units appropriate to the size of the graph.Step-by-step explanation:
1. (a) The table contains the point (0, 0), and is said to represent a linear function. Consequently, we know that function f is a proportion. Its slope is ...
y/x = 3/1 = 3.
The slope of function g is the x-coefficient, 7. Since 7 > 3, the slope of function g is greater.
(b) As we said, function f has a y-intercept of 0. The y-intercept of function g is the constant in its equation, 2. Since 2 > 0, the y-intercept of function g is greater.
__
2. (a) The y-intercept is the value when x=0, which is 665. That is the train's initial distance to destination.
(b) The average rate of change from x = 1 to x = 4 is ...
m = (285 -570)/(4 -1) = -285/3 = -95 . . . . miles per hour
The train's distance to destination is decreasing at 95 miles per hour.
(c) From part B, we know the train covers 285 miles in 3 hours, so the time to destination will be 3 hours more than 4 hours. (Distance is 285 miles at 4 hours.) The useful domain of the relation is 0 ≤ x ≤ 7.
__
3. We can write the standard form equation using the relation ...
(y2 -y1)(x -x1) -(x2 -x1)(y -y1) = 0
(29 -14)(x -2) -(5 -2)(y -14) = 0 . . . . . fill in the given points: (2, 14), (5, 29)
15x -30 -3y +42 = 0 . . . . simpify
5x -y = -4 . . . . . divide by 3 and subtract 4
(We wonder if "slope-intercept" form is desired: y=5x+4.)
(b) The above equation can be solved for y (by adding y+4), and "y" replaced by "f(x)". The result is the "functional form" ...
f(x) = 5x +4
(c) The line can be graphed by starting at the y-intercept (0, 4) and drawing a line with slope 5.
Axes will be labeled "Rental Time (hours)" (horizontal) and "Rental Cost (dollars)" (vertical).
Axes can be numbered in units appropriate to the size of the graph. (That will depend on the graph paper or tool used to create the graph.) An example of a graph is attached.

If 4 quarts of organic grapes cost $20 how many quarts can you purchase for one dollar
Answer:
4/5 of a quart
Step-by-step explanation:
Set this up as a proportion. First of all we know that 4 quarts of organic grapes cost $20, so 4x = 20. Divide and you get that x = 5 meaning 1 quart equals 5 dollars. Now if we scale this down a bit and divide by 5, we end up with 4/5 of a quart = 1$.

-2x + 17 = 11
What is x
Answer:
x=3
Step-by-step explanation:
Final Answer:
x = 3
Solution:
equation: -2x + 17 = 11
Step 1: subtract 17 in both sides
-2x + 17 = 11
-2x + 17 - 17 = 11 - 17
-2x = 11 - 7 (solve for -2x: 11 - 7)
-2x = -6
Step 2: divide -2 in both sides then solve for x.
-2x = -6
-2x -6

Figure ABCD is a kite. Find the
value of x.
Answer:
x=5
Step-by-step explanation:
in order for this figure to truly be a kite, AD and AB have to be equal.
So:
4x=x+15
now we must solve the equation:
3x=15
x=5
The value of x for the expression of the sides will be x=5.
What is geometry?Geometry is one of the oldest branches of mathematics, along with arithmetic. It is concerned with spatial properties such as figure distance, shape, size, and relative position.
Given that the sides of the given shape of the kites are AB = 4x and AD = x +15. Since the sides are equal the value of x will be calculated as,
In order for this figure to truly be a kite, AD and AB have to be equal.
4x=x+15
Now we must solve the equation:
3x=15
x=5
Hence, the value of x will be 5.

A $270 suit is marked down by 20%. Find the sale price
Answer:
Marked down means the price has decreased by 20% so 100%-20%=80%
The suit is now 80% of its original price of 270.
So 270×(80/100)= 216
The selling price of the suit will be equal to $216.
The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
