C. "They are perpendicular to each other."
Step-by-step explanation:
For a shape to be reflected, it must be reflected across a line.
The true statement about the relationship between segments M, M' and the x-axis is that (c) they are perpendicular to each other
Given that:
Shape: rectangle LMNOReflection line: x-axisWhen the shape is reflected across the x-axis, we have the following perpendicular and congruent lines
L x-axis and L' x-axis M x-axis and M' x-axis N x-axis and N' x-axis O x-axis and O' x-axisHence, the relationship between segments M, M' and the x-axis is that (c) they are perpendicular to each other

What is Eight times the sum of a number and -192 gives 96?
Answer:
Step-by-step explanation:
8x-192=96
8x-192+192=96+192
8x=288
8x/8=288/8
x=288/8
36
The unknown number is 204.
Important Information:
Eight times the sum of a number and -192 gives 96Linear equation:Let [tex]x[/tex] be the unknown number.
Sum of a number and -192 is
[tex](x+(-192))=x-192[/tex]
Eight times the sum of a number and -192 gives 96.

A veterinarian knows that the supplement glucosamine is beneficial for dogs’ joints. He wants to determine if a supplement with both glucosamine and chondroitin would be more beneficial than glucosamine alone for dogs’ joint health. The veterinarian asks the owners of dogs with known joint issues if they would be willing to have their dog participate in his study, and 32 owners agree to the study. Sixteen dogs are randomly assigned to the glucosamine group and the remaining 16 are assigned to the glucosamine with chondroitin group. After 6 months, the dogs’ joint health is measured for each treatment and compared. The results of the study were inconclusive and the veterinarian decides to do the experiment again. He gets 24 volunteers and decides that he needs to use a randomized block design.
Which variable would not be an appropriate variable for blocking?
age
size
color of coat
breed
Answer:
Colour of coat
Step-by-step explanation:
We are told that the veterinarian wants to determine if a supplement with both glucosamine and chondroitin would be more beneficial than glucosamine alone for dogs’ joint health.
In randomized block design, blocking is the arrangement of experimental units in groups known as blocks which are similar to one another.
Looking at the options given, by blocking on size, age or dog breed, the source of variability which led to the inconclusiveness initially would be controlled which then leads to a greater accuracy in result. Since there can be big, medium and small size of dog: there can be older or younger dogs: there can be different type of dog breeds as well. All these can likely affect the results of the experiment.
Whereas, blocking on colour of coat is not an appropriate variable because it has no effect on the experiment.

Answer:
2/15.99 = 0.34 euros is the right answer.
part 1: the following formula gives the area of a circle, A, dependent on its radius, r.
A = πr²
solve the equation for the variable r.
part 2: using the answer from the previous question, ^^ state the value of ‘r’ if the area of the circle were equal to 37 square feet.
(you can use 3.14 to approximate the value of π in the equation”
Answer:
3.43ft
Step-by-step explanation:
Step one:
given data
the expression for the area is
A = πr²
make r subject of the formula
divide both sides by π
A/π =r²
square root both sides
r=√A/π
step two:
given that A= 37 ft^2
r= √37/3.142
r=√11.77
r=3.43ft

pls Help. If you do I will give the first person who answers 100 points
Answer:
2%
Step-by-step explanation:
so the point [tex](\sqrt{3},\sqrt{7})[/tex] is in the circumference so the distance from (0,0) to this point will be the radius of the bullseye
[tex]x=\sqrt{(\sqrt{3}-0)^2+(\sqrt{7}-0)^2}\\\\x=\sqrt{3+7}\\\\x=\sqrt{10}[/tex]
so that's the radius
so the area will be
[tex]A=\pi x^2\\\\A=\pi (\sqrt{10})^2\\\\A=10\pi[/tex]
so the percentage is
[tex]P=\frac{A}{1600}\\\\=\frac{10\pi}{1600}\\\\=\frac{\pi}{160}\\\\P\approx 0.02[/tex]
so it's 2%
If isosceles triangle ABC has a 130° angle at vertex B, which statement must be true?
O mZA= 15° and mzC= 35
O mZA+ mZB = 155°
O mZA+ mzC = 60
OMZA= 20° and m2C=30
Answer:
Option B m<ZA+m<ZB = 155° is correct option.
Step-by-step explanation:
We know that sum of angles of triangle is equal to 180°
And Isosceles triangle, 2 angles are same
So, let Angle 1 = x
Angle 2 = x
Angle 3 = 130°
Finding values of angle x
x+x+130=180
2x=180-130
2x=50
x=25
So, Angle 1 = 25 °
Angle 2 = 25°
As, angle B is greater than 90°, the sum of angles added must be greater than 90°
So, Option A, C and D can't be correct, as their sum is less than 90°
Option B m<ZA+m<ZB = 155° is correct option.
Verify:
m<ZA = 25° (as found earlier)
m<ZB = 130° (given)
So, m<ZA+m<ZB = 155°
25°+130° = 155°
The true statement about the given angles of the triangle is m∠A + m∠B = 155⁰.
Sum of angles of Isosceles triangle
The sum of angles of Isosceles triangle must add up to 180 degrees.
Base angles of the Isosceles triangleLet the base angles = x and x
x + x + 130 = 180 (sum of angles in a triangle)
2x + 130 = 180
2x = 180 - 130
2x = 50
x = 25
Given angle B = 130°
B + A = B + C = 130 + 25 = 155°
Thus, the true statement about the given angles of the triangle is m∠A + m∠B = 155⁰.
