Answer:
40 units
Step-by-step explanation:
This question is essentially asking the perimeter of the traingle
We can easily find the sides AC and BA and while you can use the distance formula to find the last side this is a right triange so we will take an easier approach
So because AC has the same y we can very easily figure out how far apart they are by subtracting (or counting) the x values
For me I got AC= 15
AB is kind of the same deal but instead subtract the y value
I got BA= 8
We can now use the a^2+b^2=c^2 formula to get the length of the last side
8^2+15^2=c^2
This means that 289=c^2
take the square root of both sides to get
c=17
The final step is to get the perimeter which is 17+8+15 or 40

Answer:
the trip would be 800 miles all together
Step-by-step explanation:
if you divide 240/3 it is 80 which means that 80 miles is 10% of the trip so you can multiply 80 by 10 to see that 800 miles is 100% of the trip.
at a sale, dresses sold for 22.00 each. This price was 55% of a dress's original price.
Answer:
22.00x55%=12.10. 22-12.10=9.90
Answer:
$40
Step-by-step explanation:
22/55 = dollar per percent
dollar per percent = 0.4
0.4 x 100 will equal to 100% of the original price
0.4 x 100 = 40
to check, 40 x 55% = 22

Which equation has a graph parallel to the graph of 9x + 3y =22?
Answer:
y = -3x + 8.3
Step-by-step explanation:
You need to rearrange 9x + 3y = 22 in the form y = mx +c.
9x+3y = 22
3y = -9x +22
y = -3x + 7.3
As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.

Solve the system by substitution.
y = 3x
y = -4x – 49
Answer:
Step-by-step explanation:
Substitute 3x into y=-4x-49
y=−4x−49
3x=−4x−49
3x+4x=−4x−49+4x(Add 4x to both sides)
7x/7=−49/7
(Divide both sides by 7)
x=−7
Step: Substitute−7forxiny=3x:
y=3x
y=(3)(−7)
y=−21(Simplify both sides of the equation)
Answer:
x=−7 and y=−21
The solution set to the given system of equation is (- 7, - 21).
Differentiate between a mathematical function, equation and expression? Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionExpression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operatorsEquation : A mathematical equation is used to equate two expressions.Given are the system of equations as follows -
y = 3x
y = - 4x - 49
We have the equations as -
y = 3x .... Eq [1]
y = - 4x - 49 .... Eq [2]
Now, we can write the equation [2] as -
3x = - 4x - 49
7x = -49
x = - 7
So, we can find the value of [y] as -
y = 3x
y = 3 x - 7
y = - 21
Therefore, the solution set to the given system of equation is (- 7, - 21).

Solve x-34=78 find the value of x
Answer:
112 is the answer
Step-by-step explanation:
to find the value of x, you need to add both the numbers 34 and 78 to find x.
Answer:
x=112
Step-by-step explanation:
x=78+34
(here the 34 passes to the other side, and because it is substracing, you pass it adding)

What is the distance between the points (25 , 12) and (9 , 12) in the coordinate plane? A. 8 units B. 34 units C. 16 units D. 13 units
Answer:
The answer to the question provided is 16 units.
.
Step-by-step explanation:
☆Well, we simply use the distance formula, which is:
[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }[/tex]
...
☆All we need to do is plug in!
[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} } \\ \\ d = \sqrt{(9 - 25) {}^{2} + (12 - 12)^{2} } \\ d = \sqrt{( - 16)^{2} + (0) ^{2} } \\ d = \sqrt{256 + 0} \\ d = \sqrt{ 256 } \\ d = 16[/tex]

The data shows 68% percent of the area under the normal
distribution. This is equivalent to:
Answer: Plus or minus 1 standard deviation from the mean.
Step-by-step explanation:
According to the Empirical rule,
If the population is normally distributed then, about 68% of the population lies within 1 standard deviation from the mean value.
Here, the data shows 68% percent of the area under the normal distribution.
This is equivalent to "plus or minus 1 standard deviation from the mean."
Hence, the correct option is : plus or minus 1 standard deviation from the mean.

In the diagram, triangle QRS is congruent to triangle XYZ. Find the measure of angle R.
Answer:
the correct answer is C. 75°
The value of ∠R = 75⁰
What are congruent triangles?The measurements of the sides and angles of two or more triangles determine whether they are congruent. A triangle's size is determined by its three sides, and its shape is determined by its three angles. If the pairs of their corresponding sides and angles are equal, two triangles are said to be congruent.
Given ΔQRS ≅ ΔXYZ
for congruency the sides and angle of both the triangles should be equal so for ΔQRS and ΔXYZ ; QR = XY, QS = XZ, and RS = YZ and
∠Q = ∠X, ∠S = ∠Z and ∠R = ∠Y
from figure ∠Q = ∠X = 55⁰, ∠S = ∠Z = 50⁰
sum of angle of triangle is 180⁰,
∠Q + ∠S + ∠R = 180⁰
∠R = 180 - 55 - 50
∠R = 75⁰
Hence ∠R = 75⁰

Given the Vertex (1,0) and the Directrix y = -¼, find the equation of the quadratic
(x - 1)2
(x + 5)2
2(x - 1)2
-x2 - 1
Answer:
y = (x - 1)²
Step-by-step explanation:
A parabola is the locus of a point such that its distance from a fixed point (known as the focus) and a fixed line (known as the directrix) is always constant. The equation of a parabola is a quadratic equation.
The equation of a parabola with a horizontal directrix is given by:
(x - h)² = 4p(y - k).
Where the directrix (y) = k - p, vertex = (h, k)
Given that: Vertex (1,0) and the Directrix y = -¼, Therefore:
vertex = (h, k) = (1, 0). h = 1 and k = 0.
y = k - p
but y = -1/4. Hence:
-1/4 = k - p
p = k + 1/4
p = 0 + 1/4
p = 1/4
Since the equation of the parabola is:
(x - h)² = 4p(y - k).
Substituting:
(x - 1)² = 4(1/4)(y - 0)
(x - 1)² = y
y = (x - 1)²
y = x² - 2x + 1
