A windowpane is 20 centimeters tall and the diagonal distance from one corner to the other is
25 centimeters. How wide is the windowpane?
centimeters
Answer:
The windowpane is 15 centimeters wide.
Step-by-step explanation:
Use the Pythagorean theorem:
a^2 + b^2 = c^2
20^2 + b^2 = 25^2
400 + b^2 = 625
b^2 = 225
b = 15

Answer: x = 250
Step-by-step explanation:
-17 + x/5 = 33
+17 on each side to get rid of the 17
x/5 = 50
Multiply each side by 5 to cancle out the 5 and isolate the variable
x = 250
Which of the following graphs represents a function? If you don’t know then please don’t write “i don’t know” or “I can’t help with that” Just for points.
Answer:
B. x
Step-by-step explanation:
The answer would be graph x. A function must be that one x value should only have one y value. graph w doesn't work since when you plug in 0, you get two y's. same thing with z. Y doesn't work since at x value of 3, it curves back so x value 2 has 2 y's. X is the only one that each x value has only one y.
Answer:
X
Step-by-step explanation:
For a relationship to be a function, every input has exactly one output, so for every x value there is only one value.
If you look at answer's w and z for x=1 there is two y values, therefore they are not functions, letter Y is tricky. Even though every x value has only one y value, If you were to extend the graph x=0 would have more than one y values.
That leaves X. If you extend the graph of X every x value will only have one y value so it is a function
solve for -5x < 2 step by step
Answer:
x > -2/5
Step-by-step explanation:
To solve this, you need to divide -5 on both sides to isolate x.
-5x < 2
x > -2/5
Because we divided by a negative number, the sign has to change direction.
Find the y value for the point that divides the line segment XY into a ratio of 1:2. Segment XY is shown. X is at -6, -1 and Y is at 5, 1.
A. −0.3
B. 6.2
C.3
D. 2.8
I believe its -0.3, but I'm not completely sure.
Answer:
-0.3
Step-by-step explanation:
I think it is -0.3 because the other ones wouldn't make any sense if you put in on the number line but I'll come back when I finish the test to tell you if its right :)
Edit** It is correct I just took the test :)
For the point that divides the line segment XY into a ratio of 1:2,

Option A is correct
What is section formula?In coordinate geometry, Section formula is used to find the ratio in which a line segment is divided by a point internally or externally. It is used to find out the centroid, incenter and ex-centers of a triangle.
Given point
X = ([tex]x_{1},y_{1}[/tex]) = (-6,-1)
Y = ([tex]x_{2} ,y_{2}[/tex]) = (5,1)
Ratio = 1:2
For point (x1, y1) and (x2, y2) on coordinate plane if is divided in ratio of m:n.
Then section formula is given by [tex](\frac{mx_{2}+nx_{1} }{m+n},\frac{my_{2}+ny_{1} }{m+n})[/tex].
Using the section formula,
[tex](\frac{mx_{2}+nx_{1} }{m+n},\frac{my_{2}+ny_{1} }{m+n})[/tex]
= [tex](\frac{(1)(5)+2(-6)}{1+2} , \frac{1(1)+2(-1)}{1+2})[/tex]
= [tex](\frac{5-12}{3} ,\frac{1-2}{3})[/tex]
= [tex](\frac{-7}{3} ,\frac{-1}{3})[/tex]
x = -2.3 and y = -0.3
For the point that divides the line segment XY into a ratio of 1:2,
y value is -0.3.
Option A is correct

Answer:
C 296 ft
Step-by-step explanation:
hypotenuse^2 = side1^2 + side2^2
==> hypotenuse^2 = 10^2 + 14^2
==> hypotenuse^2 = 100 + 196
==> hypotenuse^2 = 296
==> hypotenuse = square root (296)
==> hypotenuse = 17.2046505
The length of the missing side = 296 in radical form
Marcos is flying a kite 35 feet above an oak tree. The angle of elevation to the top of the tree is 16 degrees and the angle of elevation to the kite is 25 degrees. What id the distance, b, to the nearest foot marcos is standing from the tree?
9514 1404 393
Answer:
195 ft
Step-by-step explanation:
The relationship between the horizontal distance, angle, and vertical height is given by ...
Tan = Opposite/Adjacent
Referring to the attached diagram, we have ...
tan(16°) = BT/MB
tan(25°) = BK/MB
Solving for BT and BK, we can describe their difference as ...
BT = MB·tan(16°)
BK = MB·tan(25°)
BK -BT = 35 = MB(tan(25°) -tan(16°))
Dividing by the coefficient of MB gives ...
MB = 35/(tan(25°) -tan(16°)) = 35/0.179562
MB = 195 . . . feet
Marcos is standing 195 feet from the base of the tree.

What number is half way between 60 and 110
Answer:
85
Step-by-step explanation:
85 is half way between 60 and 110.
Half way means the middle point from where both the point are at equal distance.
Given two numbers as follows:
Number1=60
Number2=110
To calculate a half way number between two number as follows:
=(Number1+Number2)/2
=(60+110)/2
=85
To check weater 85 is half way between 60 and 110
subtract 60 from 85 we get 25
subtract 85 from 110 we get 25
Thus both the numbers are 25 units away from 85.
So, 85 is half way between 60 and 110.

Find the next three terms of the following arithmetic sequence. -10, -3, 4, 11, (Three missing numbers)
Answer:
You can find the difference of two numbers easier if you take the absolute value of them (which is canseling out the negative or positive of them, and figuring out how far away from 0 they are) |-10| = 10, |-3| = 3, the difference between 10 and 3 is 7. The only problem that arises is now we are dealing with and negative and a positive, for this one you must see that to get from -3 to zero, you need to add 3, and to get from 0 to 4, you need to add 4, if you add 3, and then 4, you get 7
The difference between 10 and 3 is 7
The difference between -3 and 4 is 7
So naturally, the next number will be 4 + 7 = 11

Answer:
2 1/2
Step-by-step explanation:
Answer:
2 1/2
Step-by-step explanation:
Since P is at -4 and you want a number that is 6 1/2 units away from it. You are either adding 6 1/2 to it or subtracting 6 1/2 to that number.
-4 + 6 1/2 = 2 1/2
-4 - 6 1/2 = -10 1/2
Also if you count 6 and 1/2 notches in either directions from -4, you will also get both of those answers.
The multiple choice only gives you the 2 1/2 option so that is the one they are looking for.

A cylinder has a diameter of 20cm.
The height of the cylinder is 3/5 the length of the diameter.
Calculate the volume of the cylinder in terms of π
Answer:
V = 1200π
Step-by-step explanation:
Volume of a cylinder formula:
V = πr²hLet's find the height of the cylinder by multiplying 20 cm by 3/5.
20 * 3/5 = 60/5 = 12 cmThe radius is 1/2 of the diameter, so:
20 * 1/2 = 20/2 = 10 cmSubstitute 12 for h and 10 for r into the volume formula.
V = π(10)²(12)Simplify.
V = π * 100(12) V = π * 1200The volume of a cylinder, in terms of π, is V = 1200π.

on a graph there are two points (0,3) and (8,0) what is the proper equation
Answer:
The line equation of the line is:
[tex]y=-\frac{3}{8}x+3[/tex]Step-by-step explanation:
Given the two points
(0,3)(8,0)Finding the slope between (0,3) and (8,0)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(8,\:0\right)[/tex]
[tex]m=\frac{0-3}{8-0}[/tex]
[tex]m=-\frac{3}{8}[/tex]
Therefore, the slope of the line: m = -3/8
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = -3/8 and the point (0,3)
[tex]y-3=-\frac{3}{8}\left(x-0\right)[/tex]
[tex]y-3=-\frac{3}{8}x[/tex]
Add 3 to both sides
[tex]y-3+3=-\frac{3}{8}x+3[/tex]
Simplify
[tex]y=-\frac{3}{8}x+3[/tex]
Therefore, the line equation of the line is:
[tex]y=-\frac{3}{8}x+3[/tex]what would the perimeter of this shape if we enlarged it by a scale of 2.5?

Answer:
(3x+21)(x-5)
Step-by-step explanation:
To solve this let's create an equation that has intercepts at -7 and 5
To do this we get the following
(x+7)(x-5)
Now we need to make sure that the line passes through (4,-33) To do so we will plug in 4 to see how far off we are
If you plug in 4 into x you should get -11
To make y= -33 we simply need to put a three in the front and then distribute it to the first bracket
So we have
3(x+7)(x-5)
then distribute the 3 to get
(3x+21)(x-5)
