Answer:
the length of the side XY is 4 units
Step-by-step explanation:
To find the length of side XY, what we do is to find the distance between the points X and Y
To find this distance, we employ the use of the formula for finding the distance between two points on a Cartesian plane.
Mathematically, the distance d which represents the length XY is given by;
d = √{(x2-x1)^2 + (y2-y1)^2}
Where point X represents the coordinates (x1,y1) = (10,1) while point Y represents the coordinates (x2,y2) = (10,-3)
Plugging these values into the formula, we have;
d = √{(10-10)^2 + (-3-1)^2}
d = √{(0)^2 + (-4)^2}
d = √(0 + 16)
d = √(16)
d = ± 4
but since distance cannot be negative, we ignore the -4 and thus we choose 4 units as the length between the points XY
Answer:
4 units

Its because we need to find the number that it has grown.
so we add the number that it grew to the size it was before.
Answer: 1.85 + x = 5.30
Step-by-step explanation: If we know that Ethan planted a tree that was 1.85 meters tall from the start and several years later it's 5.30 meters tall, we know that something must have been added to the 1.85 in order to get 5.30 meters tall. Since we don't know what that value is, we can use x.
X is an example of a variable. A variable is just a letter that represents any number so in this case, it represents how much the tree has grown over a time period of several years.
So we can write this as 1.85 + x = 1.30.

How do we find the area of this shape?
What you have to do is find the area of the whole rectangle, then subtract of the empty parts:
50*48-0.5(50-41)(48)-6.5(pi(5/2)^2)-1.5pi(4^2)-pi(5^2)-pi=1899.293mm^2
Explanation:
The first subtraction is the area of the triangle. The rest are the combined areas of the circles and semicircles (semicircles are just half the area of a circle)
Answer:
1899.293mm^2
Kim's furniture store is offering a 40% discount on all its armchairs. Using a proportion, find the discount of the price of an armchair that originally cost $489.00. A. $489.40 B. $190.71 C. $195.60 D. $293.40
Answer:
Your answer is C.
Step-by-step explanation:
[tex]\frac{40}{100} = .4[/tex]
To find the the discount, you need to multiply the original price by the percentage.
[tex]489 *.4 = 195.6[/tex]
The discount of the chair would be [tex]195.6[/tex]

What is the solution to the inequality |X-4 <3?
0 -7
O 1
X<-7 or x<-1
O x> 1 or x<7
Answer:
|X - 4| < 3 is equivalent to 1 < X < 7.
Step-by-step explanation:
Given
|X - 4| < 3
Required
Solution of the inequality
The options are not properly presented. However, I'll solve the question without considering the options.
To simplify the given inequality, it's worth knowing that the absolute function of any inequality returns the positive form of any value it takes (whether negative or positive).
Since, we've understood that the absolute can take negative of positive, the above inequality can take the following form
-3 < X - 4 < 3
Add 4 through
4 - 3 < X - 4 + 4 < 3 + 4
1 < X < 7.
Hence, |X - 4| < 3 is equivalent to 1 < X < 7.
On a coordinate plane, a red line, labeled g of x, begins on a negative slope, crosses the x-axis at (negative 2, 0), the y-axis at (0, negative 2), and crosses the x-axis on a positive slope at (2, 0). A straight blue line with a negative slope, labeled f of x, crosses the y-axis at (0, 2) and the x-axis at (2, 0). Which statement is true regarding the functions on the graph? f(2) = g(2) f(0) = g(0) f(2) = g(0) f(0) = g(2)
Answer:
a
Step-by-step explanation:
because the lines crossover at to and in the parentheses so the x is it which makes a right.
The statement that is true regarding the functions on the graph is that f(2) = g(2).
What is a graph functions?Graphing functions is known to be the drawing of any curve that shows the function that can be seen on the coordinate plane.
Note that If a curve (graph) stands for a function, then all the point on the curve is one that satisfies the equation of the function.
Note that the linear function Since the x - axis starts with 2 it is also true to say that the y axis will also have a positive value and as such, The statement that is true regarding the functions on the graph is that f(2) = g(2).

hello :
f(1)=-3
f(n)=2f(n-1)+1
n=2 : f(2) = 2f(2-1)+1 = 2f(1)+1 but f(1) = -3
so : f(2)=2(-3)+1 =-6+1=-5

Jessie lives in a farm and only has 2 animals, chickens and rabbits. One day he decided to count the total number of heads and legs of his animals. He told his friends that there were 30 heads and 76 legs in all.
How many chickens does Jessie have on his farm?
How many rabbits does Jessie have on his farm?
Let x represent number of rabbits and y represent number of chickens.
We have been given that Jessie told her friends that there were total 30 heads for both animals. This means that there are total 30 animals.
[tex]x+y=30...(1)[/tex]
[tex]y=30-x...(1)[/tex]
We have been given that Jessie only had chicken and rabbits. We know that a rabbit has 4 legs, so total number of legs for x rabbits would be [tex]4x[/tex].
We know that a chicken has 2 legs, so total legs of y chickens would be [tex]2y[/tex].
Since all animals has 76 legs in all, so we can represent this information in an equation as:
[tex]4x+2y=76...(2)[/tex]
Upon substituting equation (1) in equation(2), we will get:
[tex]4x+60-2x=76[/tex]
[tex]2x+60=76[/tex]
[tex]2x+60-60=76-60[/tex]
[tex]2x=16[/tex]
[tex]\frac{2x}{2}=\frac{16}{2}[/tex]
[tex]x=8[/tex]
Therefore, Jessie have 8 rabbits on his farm.
Number of chickens would be [tex]y=30-x\Rightarrow 30-8=22[/tex].
Therefore, Jessie have 22 chickens on his farm.

Dustin works in a department store. He earned $89.00 for working 10 hours last week. At this rate, how much would Dustin earn for working 38 hours?
Answer:
$338.20
Step-by-step explanation:
Find out how much Dustin gets for one hour of work, since you are given how much Dustin earns in 10 hours, you divide it by 10 (the number of hours) to find one hour,
89/10=8.9
$8.9 per hour
So 38 hours would be
8.9 x 38= $338.20

x = 12.6
Step-by-step explanation:
When you have one fraction equated to another one, the means-extremes property allows you to cross multiply, as follows:
[tex]\frac{a}{b} = \frac{c}{d} [/tex]
can be rewritten as:
a*d = c*b

KL and HJ are perpendicular so the form right angles. (a) What is the
measure of angle MPJ?
Answer:
124

<KPJ is 90 degrees and <MPH= 56 degrees.
<HPM + <MPK + <KPJ =180 (Supplementry angles)
56+ <MPK +90=180
<MPK = 34
