Answer:
y = -1/2x + 2.5
Step-by-step explanation:
- slope of a perpendicular line is the negative reciprocal of the original slope (2 in this case) so y = -1/2 x + c
- to find c we substitute the values from the given point into the equation
(0) = -1/2*(5) + c
- rearrange and calculate and you'll get c = 5/2 or 2.5
- replace the value of c and now you've got y = -1/2x + 2.5

√194 i think
Step-by-step explanation:
Answer:
[tex]\boxed {d = \sqrt{194}}[/tex]
Step-by-step explanation:
Use the Distance Formula to help you find the distance between the two given points:
[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
First point: [tex](x_{1}, y_{1})[/tex]
Second point: [tex](x_{2}, y_{2})[/tex]
-Substitute the two given points onto the formula:
First point: [tex](3, 9)[/tex]
Second point: [tex](-10, 4)[/tex]
[tex]d = \sqrt{(-10 - 3)^{2} + (4 - 9)^{2}}[/tex]
-Then, you solve for the distance:
[tex]d = \sqrt{(-10 - 3)^{2} + (4 - 9)^{2}}[/tex]
[tex]d = \sqrt{(-13)^{2} + (-5)^{2}}[/tex]
[tex]d = \sqrt{169 + 25}[/tex]
[tex]\boxed {d = \sqrt{194}}[/tex] (since the number cannot be square rooted, the number will stay the same)
Therefore, the distance is [tex]\sqrt{194}[/tex].

Answer:
R=50 degrees
Step-by-step explanation:
All of the angle measures together are 180 degrees. You need to make an equation in order to solve this problem:
180= (3x+5) + (11x-1) + (5x+5)
You then combine like terms:
180= (3x+11x+5x) + (5-1+5)
180= 19x+9
Then, subtract 9 from 180:
171= 19x
Then, divide 171 by 19:
9= x
Finally, you plug the value of x into the equation representing angle R:
5 x 9 + 5
45 + 5

Answer:
x = 45
Step-by-step explanation:
The 2 interior angles of the triangle adjacent to both 3x's is
180 - 3x
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2x is an exterior angle of the triangle, thus
180 - 3x + 180 - 3x = 2x , that is
360 - 6x = 2x ( add 6x to both sides )
360 = 8x ( divide both sides by 8 )
45 = x

38h-24 is the expression represents the perimeter, in centimeters, of the rectangle
What is Area of Rectangle?The area of Rectangle is length times of width.
The width of a rectangle measures (10h-4) centimeters
Length measures (9h-8) centimeters
The perimeter of rectangle=2(Length+Breadth)
=2(10h-4+9h-8)
Add the like terms in parenthesis

For each problem, explain or show your reasoning, a. 160 is what percentage of 40? b. 40 is 160% of what number? c. What number is 40% of 1602
Answers
Answer:
A. 160 Out of 40 is 400%./// B. The answer is 25/// C. The answer is 3905%
Step-by-step explanation:
( A ) One step solution:
You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.
So, 160 is 40% of = 160 X 100 = 400
40
( B ) The same thing as A but the numbers are switched
One step solution:
You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.
So, 40 is 160% of = 40 × 100 = 25
160
( C ) Working out a percentage increase or decrease between two numbers is pretty simple. The resulting number (the second input) is 1602 and what we need to do first is subtract the old number, 40, from it:
1602 - 40 = 1562
Once we've done that we need to divide the result, 1562, by the original number, 40. We do this because we need to compare the difference between the new number and the original:
1562 = 39.05
40
We now have our answer in decimal format. How do we get this into percentage format? Multiply 39.05 by 100?
39.05 x 100 = 3905%
160 is percentage of 40, 40 is 160% , number is 40% of 1602 are 64 , 64 and 640.8 respectively.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Problem A,
40% of 160 = 160 x 40 / 100
= 64
Problem B,
160% of 40 = 160 x 40 / 100
= 64
Problem C,
40% of 1602 = 1602 x 40 / 100
= 640.8
Therefore, 160 is percentage of 40, 40 is 160% , number is 40% of 1602 are 64 , 64 and 640.8 respectively.

Bradley estimated the height of a tree at 2.5 meters. Carla estimated that tree's height at 8 feet.
How could a conversion ratio be used to compare Bradley's and Carla's estimates of the tree's height when measured in feet? (1 foot = 0.305 meters)
Answers
Answer: 4.1 feet : 4 feet
Step-by-step explanation:
From the question, we are informed that Bradley estimated the height of a tree at 2.5 meters. Carla estimated that tree's height at 8 feet.
The conversion ratio be used to compare Bradley's and Carla's estimates of the tree's height when measured in feet goes thus:
Since 1 feet = 0.305 meters
2.5 meters will be = 2.5/0.305 = 8.2 feet
Therefore the conversion ratio will be:.
= 8.2 : 8
Reducing to lowest term will be
= 4.1 feet : 4 feet.
= 4.1 : 4

Answer:
1- A. 3(10÷2) +2·7
2- A. 0.4
3- B. -2.8
4- C. n·6 - 12 = 60
Step-by-step explanation:
Heres the work in case teachers ask:
1. The given expression evaluates to ...
30÷2 + 2·7 = 15 + 14 = 29
A: 3(10÷2) + 2·7 = 3·5 + 2·7 = 15 + 14 = 29 . . . . . this will make it true
B: 30÷(6+2)·7 = (30/8)·7 = 210/8 = 26 1/4 . . . . . . ≠ 29
C: 3(10)÷(2+2)·7 = 30/4·7 = 210/4 = 52 1/2 . . . . . ≠ 29
D: (5+2)·7 = 7·7 = 49 . . . . . . . . . . . . . . . . . . . . . . . ≠ 29
2. You can divide the equation by 10 to find the appropriate value of x.
4/10 = 10x/10 = x . . . . . 4/10 matches choice A
3. The expression simplifies to ...
7.5 -10.3 = -2.8 . . . . . . matches choice B
