HELP QUICK PLS, For each of the figures, write Absolute Value equation in the form
x−c=d, where c and d are some numbers, to satisfy the given solution set.
x= -8, and x= -4
a) The absolute value equation is |x - 11| = 6.
b) The absolute value equation is |x - 0| = 1/2, which simplifies to |x| = 1/2.
To write the absolute value equation in the form |x - c| = d for the given solution sets, we need to find the midpoint (c) between the two values and the distance (d) from the midpoint to either of the values.
b) For the solution set x = 5, x = 17:
Midpoint (c) = (5 + 17) / 2 = 22 / 2 = 11
Distance (d) from the midpoint to either value (e.g., 5) = |5 - 11| = 6
So, the absolute value equation is |x - 11| = 6.
d) For the solution set x = -1/2, x = 1/2:
Midpoint (c) = (-1/2 + 1/2) / 2 = 0 / 2 = 0
Distance (d) from the midpoint to either value (e.g., 1/2) = |-1/2 - 0| = 1/2
So, the absolute value equation is |x - 0| = 1/2, which simplifies to |x| = 1/2.

Find the volume of the figure.
A brick patio measures 10ft by 12ft by 4in. Find the volume of the bricks. If the density of brick is 130 pounds per cubic foot, what is the weight of the patio in pounds?
Final answer:
The volume of the brick patio is 40 cubic feet, and by using the density of brick (130 pounds per cubic foot), the weight is found to be 5200 pounds.
Explanation:
To find the volume of the brick patio, we multiply its length, width, and height, keeping in mind to convert all dimensions to the same unit. The brick patio measures 10ft by 12ft by 4in. Since 1 foot is equal to 12 inches, the height in feet is 4in * (1ft / 12in) = 1/3 ft. Now, the volume can be calculated as follows:
Volume = Length × Width × Height
Volume = 10ft × 12ft × (1/3)ft
Volume = 120ft × (1/3)ft
Volume = 40 cubic feet.
To find the weight of the patio, we use the given density of brick, which is 130 pounds per cubic foot, and the volume that we have just calculated:
Weight = Density × Volume
Weight = 130 lbs/ft³ × 40 ft³
Weight = 5200 pounds.
The weight of the brick patio is therefore 5200 pounds.

Vanessa draws one side of an equilateral triangle ABC on the coordinate plane at points A(-2, 1) and B (4, 1). What are the two possible coordinates of vertex C? Round to the nearest tenth.
Answer:
two vertex are: (1 , 6.2) , (1 , - 4.2)
Step-by-step explanation:
A(-2, 1) and B (4, 1) AB is a parallel segment with x axis
The 3rd vertex P (x , y) will locate at the mid point of AB
x = (-2) + (4 - (-2)) /2 = 1 P (1 , y)
length AB = 4 - (-2) = 6
AP = AB (equilateral)
BP² = (4 - 1)² + (1 - y)² = 6²
1 - 2y + y² = 36 - 9 = 27
y² - 2y -26 = 0
y = ((-(-2)) ± √(-2)² - 4 x (-26)) / 2 = (2 ± √108) / 2 = 1 ± 5.2
y = 6.2 or y = -4.2
P (1 , 6.2) or P ( 1 , -4.2)
To find the possible coordinates of vertex C of an equilateral triangle with side AB on the coordinate plane, we calculate the midpoint of AB and use the length of the altitude to find two possible positions for C, approximated as (1, 6.2) and (1, -4.2).
Vanessa draws one side of an equilateral triangle on the coordinate plane at points A(-2, 1) and B (4, 1). To find the possible coordinates of vertex C, we first recognize that in an equilateral triangle, all sides are of equal length, and the altitude forms a 60-degree angle with the base.
Given points A(-2, 1) and B(4, 1), the distance AB is 6 units. Using the Pythagorean theorem in a 30-60-90 right triangle, the length of the altitude (half of the triangle height) from the midpoint of AB to C is 3√3. To find coordinate C, we add and subtract this distance from the midpoint of AB, which we calculate as ((-2 + 4)/2, (1 + 1)/2) = (1, 1).
Thus, the two possible coordinates for C are (1, 1 + 3√3) and (1, 1 - 3√3), which approximately are (1, 6.2) and (1, -4.2), rounding to the nearest tenth.

Given:
Triangles FRI and DAY are similar.
To find:
Similarity ratio
Solution:
If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.
Here, FR and DA are corresponding sides.
[tex]$\Rightarrow \frac{FR}{DA} =\frac{4}{6}[/tex]
Cancel the common factors of 4 and 6, we get
[tex]$\Rightarrow \frac{FR}{DA} =\frac{2}{3}[/tex]
⇒ FR : DA = 2 : 3
⇒ ΔFRI : ΔDAY = 2 : 3
Similarity ratio of the first triangle to the second triangle is 2 : 3.
The similarity ratio should be 2:3
Calculation of the similarity ratio;In the case when two triangles are same so the corresponding angles are congruent and the corresponding sides should be in proportion.
So,
[tex]FR \div DA = 4\div 6[/tex]
FR:DA = 2:3
Based on the above calculations, we can say that the ratio of first triangle to the second triangle should be 2:3

Last quarter, 84 seventh grade students
made honor roll. If there are 400 students in
the seventh grade, what percent made
honor roll?
Answer:
21%
Step-by-step explanation:
okay so 400 is your denominator, and 84 is your numerator, so divide 400 by 4 so you get 100, because your percentage should be out of 100. because you divided 400 by 4, you also have to do that for 84, giving you 21 out of 100. converted to a decimal its .21, or 21%
Final answer:
To find the percentage of seventh grade students who made honor roll, a proportion is used, yielding a result of 21 percent.
Explanation:
To calculate the percentage of seventh grade students who made honor roll, we can set up a proportion where 84 students is to 400 students as x percent is to 100 percent. The proportion can be written as 84/400 = x/100. To find x, we cross-multiply and solve for x.
First, cross-multiply: 84 * 100 = 400x. This gives us 8400 = 400x. Next, divide both sides of the equation by 400 to solve for x: 8400 / 400 = x. This results in x being equal to 21. Therefore, 21 percent of the seventh grade students made honor roll.

Point S is on line segment RT. Given ST = 17 and RS = 2, determine the length
RT.
Answer:
19
Step-by-step explanation:
The length of line segment RT is found by adding the lengths of the segments RS and ST. Given RS=2 and ST=17, we find that RT=2+17=19.
Explanation:In this problem, we are dealing with segments on a line. There is a concept in mathematics that's relevant here: the Whole is the sum of its parts. When you have a line divided into segments (parts), the length of the whole line is the sum of the lengths of these parts. Here, line segment RT is divided into two parts - RS and ST.
We know that RS = 2 (given) and ST = 17 (also given). Therefore, the length of line segment RT is the sum of RS and ST. RT = RS + ST = 2 + 17 = 19. So, the length of RT is 19 units.
