Step-by-step explanation:
when two lines are perpendicular to each other( the product of their slope; m1m2 = -1)
m1 = -1/m2
m1 = -1/-6= 1/6
using the formula m= y-y1 / x - x1
1/6 = y -7 /x - 3
6(y -7) = x -3
6y -42 = x - 3
6y - x -39 =0
Divide both sides by 6
y - 1/6 x - 13/2= 0
y = 1/6 x + 13/2

Answer:
2/9
Step-by-step explanation:
Answer: 2/9
Step-by-step explanation:
First write as an improper fraction.
2 5/8 is equal to 21/8
Then re-write
7/12 divided by 21/8
Then multiply 7/12 by the reciprocal of 21/8 which is 8/21
The answer is 56/252
Simplify
The answer is 2/9
∠A and \angle B∠B are vertical angles. If m\angle A=(7x-27)^{\circ}∠A=(7x−27) ∘ and m\angle B=(3x+29)^{\circ}∠B=(3x+29) ∘ , then find the value of x.
Answer:
x = 14
Step-by-step explanation:
Vertical angles are congruent , then
7x - 27 = 3x + 29 ( subtract 3x from both sides )
4x - 27 = 29 ( add 27 to both sides )
4x = 56 ( divide both sides by 4 )
x = 14

if manny the martian's shadow is 17.5 ft. in length and the shadow of a yard stick sitting perpendicular to the ground is 7.5 ft., what is manny's height
Answer:
Here the ratio of length of the shadow to the height of the object (in this case a yardstick) is 15:36. The ratio of shadow to the height of tree will also be the same. the shadow of tree is 25 feet long. So the height of tree will be (25*36)/15, that is 60 feet.

Answer:
Adam's total cost: $9.20
Cindy's total cost: $9.20
Step-by-step explanation:
Since Adam and Cyndi's total bill costs $16, evenly splitting the cost means that each of them has to pay $8, not including the tip.
To find out the dollar value of their 15% tip, multiply $8 by 0.15:
$8 × 0.15 = $1.20.
Adam and Cindy will have to pay $8 (lunch cost) + $1.20 (tip) = $9.20 separately.
The area of the parallelogram is 24 square miles find its base and height?
Answer:
Base-3 mi
Height-8 mi
Step-by-step explanation:
The area of a parallelogram is base*height.
Base*height=24
Now we just need to number that multiply to get 24. Those numbers can be 3 and 8 because 3*8=24.
The dimension of the parallelogram are 1 x 24, 2 x 12, 4 x 6, 8 x 3, and 24 x 1.
What is the area of the parallelogram?The opposite sides of the parallelogram are parallel and congruent. Let H be the height and W be the width of the parallelogram.
Then the area of the parallelogram will be
Area of the parallelogram = H × W square units
The area of the parallelogram is 24 square miles.
Then the dimension of the parallelogram is given as,
Area = 24
Area = 2 x 2 x 2 x 3
Area = 1 x 24, 2 x 12, 4 x 6, 8 x 3, 24, 1
The dimension of the parallelogram are 1 x 24, 2 x 12, 4 x 6, 8 x 3, and 24 x 1.

How do distribute equally a given value?We divide the given value by the total number of items we want to distribute.
Example:
In 35 minutes how many 5 minutes?
= 35/5
= 7
We have,
Trail distance = 13 1/2 miles = 27/2 miles
Distance travelled before every each = 2 1/4 miles = 9/4 miles
The number of 4/9 miles in 27/2 miles.
= 27/2 / 9/4
= 27/2 x 4/9
= 27x4 / 2 x 9
= 3 x 2
= 6 times.
This means on the 6th time you have already finished the trail so,
You have rested 5 times before finishing the trail.
Thus the number of rest stops before finishing the trail is 5 rest stops.

Which equations are parallel to the line -3x-6y=30? Select all that apply.
A. 2x-y=15
B. 4y=20-2x
C. x=18-2y
D. y=-3x+1
E. 5x+10y=10
F. 6-2y=4x
Answer:
B and E
Step-by-step explanation:
The slope has to be 1/2 because the equation in the question is equal to 1/2 so only B and E are parallel
The equations of the line parallel to -3x-6y=30 are 4y=20-2x and 5x+10y=10. The correct options are B and E.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line is y = mx + c. Given that the equations are parallel to the line -3x-6y=30.
To check the line parallel to -3x-6y=30 find the slope of each line and if the slope is equal to the given equation of the line then both the lines will be parallel to each other.
The slope of the given equation of the line:-
-3x-6y=30
y = ( -1 / 2 )x + 5
Slope = -1 / 2
Check all the equations:-
A. 2x-y=15 or y = -2x + 15
B. 4y=20-2x or y = ( -1 / 2 )x + 5
E. 5x+10y=10 or y = ( -1 / 2)x + 1
Therefore, equations 4y=20-2x and 5x+10y=10 are parallel to the line -3x-6y=30.
