Step-by-step explanation:
The perpendicular line *always* has a slope of the negative reciprocal. Your given line has a slope of -5, so the perpendicular slope is -1/(-5) = 1/5.
Use the point-slope form of a general line to find the equation.
(y - y_1) = m * (x - x_1)
y - 7 = (1/5) * (x - 15)
The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 30 hours and the median is 26.2 hours. Twenty-four of the families in the sample turned on the television for 15 hours or less for the week. The 11th percentile of the data is 15 hours. Step 4 of 5 : What is the value of the 50th percentile?
Answer:
26.2 hours
Step-by-step explanation:
From the given information:
The objective is to determine the value of the 50th percentile.
The median is the 50th percentile, which categorically divides the data into two equal parts. It is a number separating the higher half of a data sample from the lower half. This implies that the median stands in place for the 50th percentile of the data.
Thus, the 50th percentile value is 26.2 hours

Seth is making panels for a stained-glass window. He makes a triangular pane shaped like the triangle shown. Which of these rectangular panes has the same area as the triangular pane?
Help me please! I will mark brainliest whoever answers this with the right answer
Answer:
Options A and C
Step-by-step explanation:
Area of the triangular pane = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(14)(12)[/tex]
= 84 cm²
Area of the rectangle is given by the formula,
Area = Length × width
Option A.
Area of the rectangular pane = 12 × 7
= 84 cm²
Option B.
Area of the rectangular pane = 15 × 7
= 105 cm²
Option C.
Area of the rectangular pane = 21 × 4
= 84 cm²
Option D.
Area of the rectangular pane = 21 × 8
= 168 cm²
Option E.
Area of the rectangular pane = 28 × 6
= 168 cm²
Therefore, rectangular panes A and C have the equal area as the triangular pane has.

A rectangular farm has an area of 12 square miles. If its length is 13 miles, what is its width?
Input your answer as a fraction.
Answer:
[tex]\frac{12}{13}[/tex] miles
Step-by-step explanation:
The area of a rectangle is found by width multiplied by length. So, the width can be found by dividing the area by length.
12÷13=[tex]\frac{12}{13}[/tex]
So, your answer is [tex]\frac{12}{13}[/tex]

Sabendo que as retas r, s e t são paralelas, determine o valor de x na imagem a seguir
a)3
b)3,2
c)3,5
d)4
Answer:
x = 3.2
Step-by-step explanation:
Aquí, queremos encontrar el valor de x en la imagen de arriba.
Matemáticamente eso sería;
x / 4 = (x + 16) / (20 + 4)
x / 4 = (x + 16) / 24
Cruz multiplicar 24 * x = 4 (x + 16)
24x = 4x + 64
24x - 4x = 64
20x = 64
x = 64/20 x = 3,2
From the transversal proportionality theorem of parallel lines r,s,t. the value of x is 3.2.
It is given that r, s, t are parallel to each other. The length of the sides is given as 16, 20, 4, x. we need to find the value of x.
What is the transversal proportionality theorem?If two or more parallel lines are cut by two transversals, then they divide the transversals proportionally.
From the transversal proportionality theorem,
When r, s, t are parallel to each other then a / x = b / y
so,
[tex]\rm \frac{16}{x} = \frac{20}{4} \\\rm x = \frac{16}{5} \\\rm x = 3.2[/tex]
Therefore, from the transversal proportionality theorem of parallel lines r,s,t. the value of x is 3.2.

2.) -3(8+3h)=5h+4
3.) 2(y-6)=3(y-4)-y
4.) 8x-4=2(4x-4)
Answer:
1. [tex]x[/tex] = 9
2. [tex]h[/tex] = 2
3. Infinitely Many Solutions
4. No solution
Step-by-step explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
1.) 5(2[tex]x[/tex] + 6) = 8[tex]x[/tex] + 48
Step 1: Expand.
10[tex]x[/tex] + 30 = 8
Step 2: Subtract 30 from both sides.
10[tex]x[/tex] = 8
Step 3: Simplify 8[tex]x[/tex] + 48 − 30 to 8[tex]x[/tex] + 18.
10[tex]x[/tex] = 8
Step 4: Subtract 8[tex]x[/tex] from both sides.
10[tex]x[/tex] − 8
Step 5: Simplify 10[tex]x[/tex] − 8[tex]x[/tex] to 2[tex]x[/tex].
2[tex]x[/tex] = 18
Step 6: Simplify [tex]\frac{18}{2}[/tex] to 9.
[tex]x[/tex] = 9
2.) −3(8 + 3[tex]h[/tex]) = 5[tex]h[/tex] + 4
Step 1: Expand.
−24 − 9[tex]h[/tex] = 5
Step 2: Add 24 to both sides.
−9[tex]h[/tex] = 5
Step 3: Simplify 5[tex]h[/tex] + 4 + 24 to 5[tex]h[/tex] + 28.
−9[tex]h[/tex] = 5
Step 4: Subtract 5[tex]h[/tex] from both sides.
−9[tex]h[/tex] − 5
Step 5: Simplify −9[tex]h[/tex] − 5[tex]h[/tex] to −14[tex]h[/tex].
−14[tex]h[/tex] = 28
Step 6: Divide both sides by −14.
[tex]h[/tex] = [tex]-\frac{28}{14}[/tex]
Step 7: Simplify [tex]\frac{28}{14}[/tex] to 2.
[tex]h[/tex] = 2
3.) 2([tex]y[/tex] − 6) = 3([tex]y[/tex] − 4) − [tex]y[/tex]
Step 1: Expand.
2[tex]y[/tex] − 12 = 3
Step 2: Simplify 3[tex]y[/tex] − 12 − [tex]y[/tex] to 2[tex]y[/tex] − 12.
2[tex]y[/tex] − 12 = 2 − 12
Step 3: Since both sides equal, there are infinitely many solutions.
Infinitely Many Solutions
4.) 8[tex]x[/tex] − 4 = 2(4[tex]x[/tex] − 4)
Step 1: Expand.
8[tex]x[/tex] − 4 = 8
Step 2: Cancel 8[tex]x[/tex] on both sides.
−4 = −8
Step 3: Since −4 = −8 − 4 = −8 is false, there is no solution.
