Perpendicular lines have slopes that are opposite reciprocals.
This means we take a number, flop it over, and change its sign.
So the slope of the given line is -2
Flop it over:
-1/2
Change its sign:
1/2
Now, let's write the equation in point-slope form:
y-y1=m(x-x1)
y-(-5)=1/2(x-(-4)
y+5=1/2(x+4)
y+5=1/2x+2
y=1/2x+2-5

ratio of a rectangle's length to its width is 4:7. If the longer side is 31.5in., find the width, the perimeter, and the area of this rectangle.
Answer:
Step-by-step explanation:
Ratio of length : width = 4 : 7
Length = 4x
Width = 7x
Longer side = 31.5 in
⇒ 7x = 31.5
Divide both sides by 7
x = 31.5/7
x = 4.5
length = 4x
= 4*4.5
l = 18 in
width = 31.5
w = 31.5 in
[tex]\boxed{ \text {Perimeter of rectangle }= 2*l + 2*w}[/tex]
= 2*18 + 2*31.5
= 36 + 63
= 99 in
[tex]\boxed{ \text{Area of rectangle = l*w}}[/tex]
= 18*31.5
= 567 in²

first your gonna want to look at the numbers given and then solve.
prove that it is congruent
Answer:
The dashes on the side lengths mean that they are equal in length
⇒ PQ = RP
The triangles share one side PS
The figure also states that m∠QPS = m∠RPS
Therefore, the triangles are SAS congruent since they have two pairs of congruent sides and a congruent included angle.

Answer:
If 6/10 is multiple by a fraction less then one the product would be 1/2
Step-by-step explanation:
6/10 is also equal to 0.6
If 0.6 is multipled by something less then one the product would not be able to be greater then 6/10
Resulting in 1/2 being the product.

Answer:
7.6
Step-by-step explanation:
a^2 + b^2 = c^2
6.5^2 + x^2 = 10^2
42.25 + x^2 = 100
isolate x by subtracting 42.25 on both sides

Shahida has seen an eagle landing at the top of the tree in her backyard. She places a camera on a tripod a distance of 12 feet from the
trunk of the tree. She angles the camera to the top of the tree so she can get a picture of the eagle. The height of the tree is 31 feet. The
height of the tripod is 4 feet.
The angle of elevation from the tripod to the top of the tree is about 66 degrees
What is trigonometric ratio?Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let Ф represent the angle of elevation. Since the tripod is at a height of 4 feet, hence:
tanФ = (31 - 4) / 12
Ф = 66 degrees
The angle of elevation from the tripod to the top of the tree is about 66 degrees

A) t^2
B)2+t
C) t÷2
D)2t
Answer:
D: 2t
Step-by-step explanation:
a coefficient next to a variable is an automatic multiplication equation
The solution is Option D.
The number of cups of diced onions A to the number of cups of chopped tomatoes t is represented by the equation A = 2t
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is given by
A = total number of cups of diced onions
Let the total number of cups of chopped tomatoes be = t
Now , the recipe requires twice as many cups of chopped tomatoes as diced onions
Substituting the values in the equation , we get
A = 2t
where A = number of cups of diced onions
t = number of cups of chopped tomatoes
Therefore , the value of A is 2t
Hence ,
The equation will be A = 2t where t is the number of cups of tomatoes
