Chloe and Allison were comparing text messages during lunch. Allison sent 18 text messages today. Allison sent one-third of the amount of text messages sent by Chloe.
Write an equation to determine how many text messages Chloe sent.
t + 3 = 18
t divided by 3 equals 18
t − 3 = 18
3t = 18
Answers
Answer: Assuming t = the amount of text messages Chloe sent, then the answer would be the second one, t ÷ 3 = 18

1.Let k be a positive real number. The line x + y = k and the circle x^2 + y^2 = k are drawn. Find k so that the line is tangent to the circle.
2.Let A = (6,2), and let B be the reflection of A over the line y = 1/2x + 5. Find the coordinates of B
Answers
2. The line y = 1/2x + 5 has slope 1/2, so the line perpendicular to it that passes through A = (6, 2) has slope -2. The equation of this line is y - 2 = -2(x - 6), which simplifies to y = -2x + 14. To find the reflection B of A over the line y = 1/2x + 5, we need to find the intersection of the line y = -2x + 14 and the perpendicular bisector of the segment AB. The midpoint of AB is ((6 + x)/2, (2 + y)/2), and the slope of AB is (y - 2)/(x - 6). Therefore, the slope of the perpendicular bisector of AB is -1/(y - 2)/(x - 6), which simplifies to (6 - x)/(y - 2). The equation of the perpendicular bisector of AB is y - (2 + y)/2 = (6 - x)/(y - 2)(x - 6)(x - (6 + x)/2) + (2 + y)/2. Solving the system of equations y = -2x + 14 and y - (2 + y)/2 = (6 - x)/(y - 2)(x - 6)(x - (6 + x)/2) + (2 + y)/2, we get B = (5, 8). Therefore, the coordinates of B are (5, 8).

Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.
Answers
Answer:
The total area of the back classroom wall is (20ft x 12ft) = 240ft²
The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².
Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.
Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
6
Step-by-step explanation:
18-2.5+7 there s your helllppppppppppp
New base = 18 x 2/5 = 7.2 feet
New height = 7 x 2/5 = 2.8 feet
Therefore, the dimensions of the new deck are 7.2 feet for the base and 2.8 feet for the height.
Part B: To find the area of the original deck, we can use the formula for the area of a triangle, which is:
Area = (1/2) x base x height
Area = (1/2) x 18 x 7 = 63 square feet
To find the area of the new deck, we can use the same formula and plug in the new dimensions:
Area = (1/2) x 7.2 x 2.8 = 11.88 square feet
Therefore, the area of the original deck is 63 square feet and the area of the new deck is 11.88 square feet.
Part C: The ratio of the areas is:
63/11.88 = 5.303
The scale factor is:
2/5 = 0.4
To compare the ratio of the areas to the scale factor, we can divide the ratio of the areas by the scale factor:
5.303/0.4 = 13.2575
Therefore, the ratio of the areas is 13.2575 times the scale factor.

Simplify ) 3/4 of 8/6
Answers
Answer:
First of all, to calculate what a fraction of a fraction is, we multiply them:
\(\frac{3}{4}*\frac{8}{6}\) = \(\frac{3*8}{4*6}\) = \(\frac{24}{24}\) = 1
So now we know that three quarters of 8/6 is equal to 1.
We could also simplify 8/6 dividing both numerator and denominator by the same number:
\(\frac{8}{6}=\frac{\frac{8}{2}}{\frac{6}{2}}=\frac{4}{3}\)
And see that 3/4 of 4/3 is also equal to 1:
\(\frac{3}{4}*\frac{4}{3}=\frac{3*4}{4*3}=\frac{12}{12}\) = 1
Answer: 1

Answers
Answer: 36 inches (in.)
Step-by-step explanation:
The first thing you need to do is form a right triangle from the starting point to the hole to the corner where the ball is at. Right triangles have a hypotenuse (the longest side), and two legs (the shorter sides).
We are told next to the drawing that it’s 39 feet from the staring point to the hole (given a straight line). This is the length of our hypotenuse. We are also given the length of one of the legs, with it being 36 feet.
We need to find the length of the last leg, the length from the ball to the hole. To do this, we can use the Pythagorean Theorem. The Pythagorean Theorem states that the square of each of the legs equals the square of the hypotenuse. The formula for the Pythagorean Theorem is \(a^{2} +b^{2} =c^{2}\), with \(a\) and \(b\) being the legs, and \(c\) representing the hypotenuse.
Input the given values into the formula and you get the following:
\(a^{2} +b^{2} =c^{2}\)
\(36^{2} + x^{2} =39^{2}\)
\(\sqrt{36^{2} } +\sqrt{x^2} =\sqrt{39^2}\)
\(36 +x =39\)
\(x=3\)
Therefore, the length from the ball to the hole is 3 feet (ft.).
BUT WAIT
The question asks us to provide our answer in inches (in.), and 1 foot equals 12 inches.
Therefore, the distance from the ball to the hole is 36 inches (in.).

Oy + z = x
O x + y + z = 180 degrees

Answer:
Ox+y+z=180
Step-by-step explanation:
The relationship which is always rue for the three angles x, y and z of triangle ABC is x + y + z = 180°.
What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
We know that a triangle has three angles.
Let x, y and z be the three angles of the given triangle.
We know that, the interior angles of a triangle sum up to 180°.
The given three angles are x, y and z.
So, x + y + z = 180°
Hence the correct relationship that describes all the three angles of the triangle is that x + y + z = 180°.

Answer:
It is point c
Step-by-step explanation:
ok so the coordinates are always (x,y) so therefore if X is 0 then it stays in the middle of the graph and doesn't go anywhere. since Y is -3, y always goes down or up. so if it goes down then it is negative. up is always positive. same with x. X is always horizontal so if it moves right, it is positive and left (backwards) is negative. hope this helps and isn't confusing. *Also, since it's -3, then it goes down negative 3 units. *
Answer:
C
Step-by-step explanation:
In the coordinate (x,y), x refers to the place of point above the horizontal line while y represents the place of point in the side to its vertical lines.
Here, x is 0, that means it is lying on y line and y is -3, that means it's lying in 3rd quadrant. So, point C matches them completely. That's why the correct answer is C.
