Answer:
The length of other wall is 3 meters.
Step-by-step explanation:
Given that:
Length of one wall = 4 meters
Length of diagonal from one corner to opposite corner = 5 meters
As the room is rectangular, the diagonal will form a right angled triangle.
The diagonal will be the hypotenuse.
Using pythagorean theorem;
[tex]a^2+b^2=c^2[/tex]
Here,
a = 4 and c = 5
[tex](4)^2+b^2=(5)^2\\16+b^2=25\\b^2=25-16\\b^2=9[/tex]
Taking square root on both sides
[tex]\sqrt{b^2}=\sqrt{9}[/tex]
b = 3 meters
Hence,
The length of other wall is 3 meters.

For integers a, b and k, we know that a >12, b > 20 and a < b. If b=7k, what is the value of k ?
This question is incomplete, the complete question is;
For integers a, b and k, we know that a > 12, b < 20 and a < b. If b=7k, what is the value of k ?
Answer: the value of k = 2
Step-by-step explanation:
Given that;
a > 12
b < 20
a < b
If b = 7k
Now if k = 1 {b = 7k = 7}
b would be equal to 7 but b has to be greater than 20
IT CANT BE
if k = 2 { b = 7k = 14}
b would be equal to 14, a is greater than 12, b has to be less than b; 14 < 20,
a has to be less than than b ( 12 < 14 )
IT IS
if k = 3 {b = 7k = 21}
b would be equal to 21, so b is greater than 20 and a is less than 21
IT CANT BE
Therefore the value of k = 2

Represent the following sentence as an algebraic expression, where "a
number" is the letter x. You do not need to simplify.
Twice the difference of a number and 3.
Answer:
x-3*2
Step-by-step explanation:
Assuming the lines are evenly spaced between the integers, what number, in decimal notation, is represented by the plotted point?
Answer:
-1.4
Step-by-step explanation:
There are five increments between -2 and -1, so we find the difference between -2 and -1, which is 1. Divide 1 by five (increments)=.2
This means that every increment is worth 0.2.
If we see it from the left to right, from -2, there are 3 increments to the right, so multiply three by 0.2 which is 0.6, add 0.6 to -2, which is -1.4.
Hope this helps!
Geometry Special Quadrilaterals show work please
Answer:
a = 16
w = 125
x = 120
y = 55
Step-by-step explanation:
FINDING 'a'
31 = a + 46 / 2
62 = a + 46
16 = a
FINDING 'w'
* This section looks Non-Isosceles trapezoid so I will be following the rule according it
w + 55 = 180
w = 125
FINDING 'y'
y = 55
- Because of corresponding angles
FINDING 'x'
* In this case it looks like we are still dealing w/ an non-isosceles trapezoid.
x + 60 = 180
x = 120
Hope this helped ^^

So, by converse of Pythagoras theorem given side lengths form a right triangle
Answer:
Right
Step-by-step explanation:
The side lengths are 5, 5√3, and 10. This tells me this is a 30° 60° 90° triangle. In a 30° 60° 90° triangle, the relationship between the side lengths are a, a√3, and 2a. a represents the side length of the first leg of the triangle. a√3 represents the second side length, which is the first leg's side length multiplied by √3. Finally, 2a represents the hypotenuse which is two times bigger than the first leg's side length.

Daisy is given a scale drawing with the route to her campsite.
The route to the campsite is 28 cm on the drawing.
The scale on the drawing is 1:300
What is the actual length of the route?
metres
Given that :
The route to the campsite is 28 cm on the drawing.
The scale on the drawing is 1:300
To find,
The actual length of the route.
Solution,
Let the actual length of the route be x.
Here, map distance : actual distance = 1: 300
[tex]\dfrac{1}{300}=\dfrac{28}{x}\\\\x=28\times 300\\\\x=8400\ cm[/tex]
So, the actual length of the route is 8400 cm.

Help me. I'm really confused!
Answer:
Step-by-step explanation:
Remember, the first point in a bracket like this (6, 1) is the x coordinate. Here, 6 is your x coordinate. So, if we actually had the line (which we don't have right now, it would be lined up with the number 6 on the x axis. And the second point, 1 here, is the y coordinate. Which tells you where this point falls on the y axis. it would be lined up with the number 1 on the y axis. First, let's work on the parts where you are listing the points. it seems to give you the x coordinate 2 on the first one. So on the x axis which is the horizontal line that says Number of Books Sold, go to the number 2. Then y upward with your mouse and the first point that appears with the x coordinate of 2 (it's the 2nd point if you start from the bottom of the line and go up) has the y coordinate of 20 because if you use your mouse to go left on the same gray line that point is on, you will hit 20 on the line that says Total Amount Payed (this is your y axis). Now, on the next point it just gives you the y coordinate, 40. Which means that it should be on the grey line that hits the number 40 on the Total Amount Payed line (your y axis). So if you find that point and go down with your mouse on the gray line right under it, you should hit 4. So that point is (4, 40). 6 is not labeled but it is the gray line after the 5 on the x axis. If you go up 6, you hit the to right corner of the graph and if you trace it to the y-axis, it's not labeled but it should be 60 because if you pay attention, the numbers on the y-axis are going up by 10s. The x coordinate represents The Number of Books Sold because it says that under the x axis. The y coordinate represents the Total Amount Payed (dollars). ordered pairs are like ratios because they are both pairs. Ordered pairs tell you how much to go up, down, forwards, and backwards on a coordinate plane while ratios tell you a proportion. I am including a picture to help you out. I hope this made sense and was helpful!
