The distance from the ladder to the end of the side is 5 ft. The distance from the top of the ladder to the bottom is 13 ft long! HOW TALL IS IT? WILL MARK BRAINLIEST
Answer:
12 ft
Step-by-step explanation:
Note that you have a right triangle here, with hypotenuse 13 ft, and base 5 ft. Using the Pythagorean Theorem, we find the height of the upper tip of the ladder as follows:
(13 ft)^2 = y^2 + (5 ft)^2. Then y^2 = 144 ft^2, and y =height= 12 ft
Why is it important to be careful of the order of the two letters used when naming a ray?
Answer:
Because one letter represents an endpoint and the other doesn't.
Step-by-step explanation:
Ray AB starts at endpoint A and goes through point B and then on, indefinitely.
Ray BA starts at endpoint B and goes through point A and then on, indefinitely.
They 'point' in opposite directions.
James wants to buy a house.
The price of the house is a quarter of a million pounds.
James has to pay a deposit for the house.
The deposit is 15% of the price of the house.
James already has part of the deposit.
He has £32 000
(a) How much more money does James need for the deposit?
Answer:
27,200
Step-by-step explanation:
15% of 32,000 pounds is 4,800. Just subtracting them will end you with 27,200.

Choose the triangle in which angle 2 is not an exterior angle.
help me...new freinds?
Answer:
The third triangle
Step-by-step explanation:
The Exterior Angle is the angle a side of a shape and a line extended from the side next to it.
So for example, the first picture shows an exterior angle because a line was extended and it forms an angle with the triangle's side.
The second picture is still an exterior angle because the angle is formed with an extended line and the triangle's side.
The third photo shows an angle formed between a random line and the triangle's side. This is not an exterior angle because the angle is not formed with any side's extension.
The fourth photo is an exterior angle because it shows the angle being formed with an extension of a line from the triangle and a side of the triangle.
Hope this helps! Feel free to ask any questions! :)
Answer:
C the third triangle. Hope this helps

Jordan types at a constant rate of 40 words per minute. The number of words typed, is a function of the number of minutes spent typing, Which equation models this situation?
Answer:
[tex]w = 40m[/tex]
Step-by-step explanation:
Given
[tex]Rate = 40\ words\ per\ minute[/tex]
Required
Express as an equation
Represent the number of words with w and the minutes with m.
In 1 minute, Jordan types 40 words.
In m minutes, Jordan will type 40m words.
So, the function is:
[tex]w = 40m[/tex]

Classify each angle
Name Each Angle in Four Ways
Answer:
1) Obtuse angle
2) Obtuse angle
3) Acute angle
You can do 4 and 5. I will give you a hint that acute angles are less than 90 degrees and obtuse angles are more than 90 degrees. And if it is a straight line it is 180 degrees.
6) Angle KLM, MLK, Obtuse angle, and angle 5.
7) Angle DCB, BCD, Obtuse angle, and angle 5.
You can do 8. I will give you a hint that the letters will start from end-middle-end and it can be opposite. If getting confused then look what I did. On muber 6, my I typed angle KLM and angle MLK. Both of them are same but look on how I typed. Also while naming angles, they will be in capital.
Hope this helps, thank you !!
Which values from the set {0, 1/2 , 2.5, 4} make the inequality 8g < 4 true?
Answer:
only 0
Step-by-step explanation:
8g < 4 simplifies to g < 4/8, i.e., g < 1/2
only 0 is smaller than 1/2

A jeweler sells a popular line of charm bracelets. Each bracelet includes one chain and a number of charms selected by the customer. The price of the chain is 25 dollars, and each charm costs c dollars. Which expressions represent the price, in dollars, of a charm bracelet with five charms? Select ALL that apply.
Answer:
Price of bracelet = $(25 + 5c)
Step-by-step explanation:
As given,
A bracelet = 1 chain + Number of charm selected by customer
Also given,
Price of chain = $25
Price of each charm = $c
As,
we have to write equation for a bracelet with 5 charm
So,
Price of bracelet = Price of 1 chain + Price of 5 charm
As
Price of 1 charm = $c
⇒Price of 5 charm = $5×c = $5c
∴ we get
Price of bracelet = $25 + $5c = $(25 + 5c)
7e = f
What does it mean when a letter and number are together like this
Answer:
multiplication
Step-by-step explanation:
7 x e = f
Answer:
If a number and letter are together, it means it is a multiplication problem. It is the same thing as 7 x e.
Step-by-step explanation:
We don't know what e is because there isn't a number given to us to solve the problem, so we say 7 x e = 7e, but the equation tells us that 7e = f, so 7 x e is equal to f which means 7e is equal to f.
Let me just give a number to e. Let's say e is 5
7e = f
We already know 7e is the same thing as 7 x e, so let's rewrite it
7 x e = f
We will change e to 5 and multiply the numbers together
7 x 5 = f
Now multiply 7 x 5
35 = f
If 35 is equal to f, that means the value of f is 35, so f = 35 ( I don't know if this makes sense lol)
But let's now take the original equation and assume f is 42
7e = f
Remember, 7e is 7 x e, so rewrite your equation
7 x e = f
Now we will change the f to 42
7 x e = 42
To get e, we will have to think about what multiplies by 7 to get 42. We will have to change this to division. We will divide 42 by 7
42÷7 = 6
That means e is 6. Now let's write the equation with changing e to 6
7 x 6 = 42
7 times 6 is 42, so we will multiply that
42 = 42
Now we have equal answers. Of course, 42 is equal to 42
Overall I'm trying to say 7e = f
I'll solve this again, so you won't have to go back up.
7e = f
7 x e = f
f = f
I hope this makes sense lol
Which conclusion does the diagram support?
Answer:
The conclusion supported by the diagram is;
(A) [tex]\dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]
Step-by-step explanation:
The question is examines the theorem that two transversals cut by three or more parallel lines are proportionally divided by the transversals
The given parallel lines are;
Line CD, line BE, and line line AB
The given transversals are;
Line AC and line DF
Therefore, by the above three or more parallel lines cutting two transversal theorem, we have;
BC/AB = ED/FE, BC/DF = AB/FE, CA/AB = DF/FE
From BC/AB = ED/FE, we find the inverse of both sides to get;
[tex]\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{1}{\dfrac{ED}{FE} }[/tex]
[tex]\dfrac{1}{\dfrac{BC}{AB} } = \dfrac{AB}{BC} \ and \ \dfrac{1}{\dfrac{ED}{FE} } = \dfrac{FE}{ED}[/tex]
[tex]\therefore \ \dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]
The correct option is [tex]\dfrac{AB}{BC} = \dfrac{FE}{ED}[/tex]

find an expression for the area of a rectangle of sides 2x+3 and x-1 given that the perimeter is 28cm what is the value of x
Answer:
4cm
Step-by-step explanation:
Given data
L=(2x+3)
W=(x-1)
P=28cm
A= L*W
A= (2x+3)*(x-1)
open bracket
A= 2x^2-2x+3x-3
collect like terms
A= 2x^2+x-3
P= 2L+2W
P= 2*(2x+3)+2(x-1)
P= 4x+6+2x-2
collect like terms
P= 6x-4
but p= 28
28= 6x-4
28-4= 6x
24= 6x
x= 24/6
x= 4cm
Hence x= 4cm
