10. Write an expression in simplified form to
represent the area of the trapezoid.
Answer:
48[tex]x^{7}[/tex]y
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases , then
A = [tex]\frac{1}{2}[/tex] × 4[tex]x^{5}[/tex] × (9x²y + 15x²y )
= 2[tex]x^{5}[/tex] × 24x²y
= 48[tex]x^{7}[/tex]y
The simplified expression for the area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].
What is trapezium?A trapezium is a quadrilateral with four sides where two sides are parallel to each other.
We have,
Trapezium.
Height = 4[tex]x^5[/tex]
Parallel sides are 15x²y and 9x²y.
The area of the trapezium.
= 1/2 x h x ( sum of the parallel sides )
Now,
Area of the trapezium.
= 1/2 x 4[tex]x^5[/tex] x (15x²y + 9x²y)
= 2[tex]x^5[/tex] x (15x²y + 9x²y)
= 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex]
Thus,
The area of the trapezium is 30[tex]x^7y[/tex] + 18[tex]x^7[/tex][tex]y[/tex].

N a certain year, the amount A of garbage in pounds produced after t days by an average household is given by Aequals 7.5t.
Answer:
The answer is below
Step-by-step explanation:
In a certain year, the amount A of garbage in pounds produced after t days by an average household is given by A = 7.5t.
Plot a graph for t > 0
how many days it will take to get 200 pounds of garbage.
Solution:
a) Let the time in days (t) be on the x axis and the amount of garbage (A) in pounds be on the y axis. Therefore:
At t = 0; A = 7.5(0) = 0
At t = 10; A = 7.5(10) = 75
The graph was plotted using the geogebra online graphing tool.
b) number of days require to get 200 pounds of garbage can be gotten by finding the value t for which A = 200. Therefore:
A = 7.5t
t = A / 7.5 = 200 / 7.5
t = 26.67 days
what is the range of the function f(x) =4^x+1 when the domain is {-1,0,3}
Answer:
(1,∞){y|y>1}
Step-by-step explanation:
i hope that this is what you are looking for^_^
This is just a fancy way your teacher saying that when you have an equation y=[tex]4^{x}[/tex]+1, what is y when x=-1,0,3.
We just need to solve by substituting the x in respectively.
x=-1, y=[tex]\frac{5}{4}[/tex]
x=0, y=1
x=3, y=65

Scale on a map of Ireland is 1.2 000000 how many square centimetres are represented on the map by the province of Munster.
Question is incomplete, we will however explain how the scale works using examples
Answer and explanation:
Given the map scale 1:2000000, the fraction from this 1/2000000 is the representative fraction. The representative fraction is the ratio of distance on the map to the real distance on ground.
With the representative fraction 1/2000000, we can find how many meters on the ground is represented by a unit of measurement in centimeters on the map thus:
Given 1m= 100cm
Representative fraction broken down = 1/2×10000×100
Therefore 1cm on the map = 20000m on ground

Answer:y=415 x = 21.5
Step-by-step explanation:
We can see 4x-37 = 49
4x = 86
x = 21.5
4(21.5) -3 = 83
Then we can see what the other side is because they are equal
y/5 = 83
83 x 5 = 415
y=415
24% students in a clan were absent in a day .If 38 students were present ,what is the total strength in the clan
Answer:
50 students
Step-by-step explanation:
24% students in a clan were absent in a day .
Hence, the Percentage of students present is calculated as:.
= 100 % - 24 %
= 76%
From the question, we know that:
If 38 students were present ,what is the total strength in the clan
The total strength of the clan = Total number of students. This is calculated as:
76% × x = 38 students.
76/100 × x = 38
76x /100 = 38
Cross Multiply
76x = 38 × 100
x = 3800/76
x = 50 students

An inverse variation includes the points (15,1) and (n,5). Find n
The value of n is, 75.
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
An inverse variation includes the points (15, 1) and (n, 5).
Now, We know that;
The inverse variation is defined as,
⇒ y = k x
Here, An inverse variation includes the points (15, 1) and (n, 5).
Hence, Substitute x = 15, and y = 1;
⇒ 1 = k × 15
⇒ k = 1/15
And, Substitute x = n and y = 5;
⇒ y = k x
⇒ 5 = 1/15 × n
⇒ 5 × 15 = n
⇒ n = 75

Answer:
x = [tex]11\sqrt{2}[/tex]
y = [tex]11\sqrt{2}[/tex]
Step-by-step explanation:
the ratio of the sides of a 45 - 45 - 90 triangle is shown at the bottom of this answer.
as you can see, it is x:x:[tex]x\sqrt{2}[/tex]
The side given is x[tex]\sqrt{2}[/tex], so you have:
[tex]x\sqrt{2}=22[/tex]
divide both sides by [tex]\sqrt{2}[/tex]
x = [tex]22/\sqrt{2}[/tex]
multiply this by [tex]\sqrt{2} /\sqrt{2}[/tex]
[tex]x = 22\sqrt{2}/2[/tex]
[tex]x=11\sqrt{2}[/tex]
y is also equal so y = [tex]11\sqrt{2}[/tex]

Answer:
14/s
Step-by-step explanation:
Bonnie bought 14 sponges. There were s sponges in each package. Choose the expression that shows how many packages Bonnie bought.
Number of sponges = Number of packages
Hence:
s sponges = 1 Package
14 sponges = x
Cross Multiply
s × x = 14 × 1
x = 14/s
Therefore, the expression that shows how many packages Bonnie bought.is given as
14/s
John is painting a box that is shaped like a cube. 1/10 of a bottle of paint covers 2/5 of the box. How many cubes can he paint with 2 bottles of paint?
Answer:
8
Step-by-step explanation:
1/10 bottle of paint covers 2/5 of box
2 bottles of paint will cover x of box
Using cross multiplication :
1/10 = 2 / 5
2 = x
(1 / 10)x = 2/5 * 2
x / 10 = 4 / 5
Cross multiply :
5x = 40
Divide both sides by 5
x = 40/5
x = 8
Hence, 2 bottles of paint will be used to paint 8 boxes
Find a solution to the linear equation −8x−y=24 by filling in the boxes with a valid value of x and y
Answer:
X= 24+7/8 | Y= 24-8x
Steps for answers:
For X:
1. Add y to both sides.
-8x=24+y
2. Divide both sides by -8.
x=-24+y/8
-----------------
For Y:
1. Add 8x to both sides.
-y=24+8x
2. Multiply both sides by -1.
y=-24-8x

Does the point (1, –9) satisfy the equation y = 3x − 6?
Answer:
No.
Step-by-step explanation:
Well, is the points (1, -9) does satisfy the equation y = 3x - 6. Then, substituting the values of x, and, y, into the equation y = 3x - 6, we should get a true equation.
y = 3x - 6
-9 = 3 * 1 - 6
-9 = 3 - 6
-9 = -3.
So, the points (1, -9) does not satisfy the equation y = 3x - 6.
