Answer:A decrease of 28%
Step-by-step explanation: the question says decreased so you can mark out A and B then 250-180 is 70, 70% of 250 is 28%
The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%.
What is the percentage?
The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
As per the given question,
Initial price of Airfare = $250
Final price of Airfare = $180
The percentage = change/initial × 100
Percentage decrease = (250 - 180)/250 × 100
⇒ 0.28 × 100 = 28%
Hence "The percentage is the indicating hundredth thus the percentage change from $250 to $180 is 28%".

4x-7y>10 Determine which point is a solution of the linear inequality.
Answer:
b hnhun
Step-by-step explanation:
b b jnh
Answer:
Step-by-step explanation:
Im guessing its telling you to solve using substitution ?
Well your lucky, most of the work is already done :D
you know y=x-7 , so just replace y with (x - 7) in the other equation
4x - 7(x-7) = 10
4x - 7x + 49 = 10
-3x = -39
x = 13
Now just plug X in the original equation to fine Y
y = x - 7
y = 13 - 7
y = 6
so the solution would be
(13,6)

99+72=9(11+□ )
pleas help
Answer:
9(11+8)=171 8 is your answer
Step-by-step explanation:
99+72=171
For the expression 99 + 72 = 9 (11 + x) the value of x is 8.
What are mathematical operations?Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
The given expression is,
99 + 72 = 9 (11 + x)
To find the value of x, simplify the expression by using mathematical operations,
171 = 9 (11 + x)
171 / 9 = 11 + x
19 = 11 + x
19 - 11 = x
8 = x
x = 8
The required value of x is 8.

Find the area of the triangle
Answer:
C) 17.1 square units
Step-by-step explanation:
Use Heron's formula to calculate the area of the triangle:
[tex]Area = \sqrt{s(s-a)(s-b)(s-c)}[/tex] where [tex]s=\frac{a+b+c}{2}[/tex] which represents the semi-perimeter of the triangle:
[tex]s=\frac{9.9+6.1+6}{2}=11[/tex]
Therefore:
[tex]Area = \sqrt{11(11-9.9)(11-6.1)(11-6)}\\[/tex]
[tex]Area = \sqrt{11(1.1)(4.9)(5)}\\[/tex]
[tex]Area = \sqrt{296.45}\\[/tex]
[tex]Area = 17.2[/tex]
Therefore, the closest answer choice is C) 17.1 square units
Please help meee! (Solve area)
Answer:
First we can do (12*4)- thats the top rectangle. Remember area is base times height.
48
Next lets do (8*12)-thats the middle rectangle
48+ 96
Now the triangles.
you can just do 2*8/2 because a triangle is half of a rectangle.
48+ 96+ 8
add 8 again because theres 2 triangles-
48+96 + 8 +8
Your answer is 160
I hope this helps you!

A number x added to a number y is equal to 100. The number y is also equal to 10 more than the number x doubled. Write and solve a linear system to find the value of x and y.
Answer: x + y=100---equation 1
y =10+ 2x-----equation 2
x=30, y=70
Step-by-step explanation:
Given that
x added to a number y is equal to 100 which means that
x + y=100
and also that
y is also equal to 10 more than the number x doubled which is
y =10+ 2x
we have the linear systems to solve the equations as
x + y=100---1
y =10+ 2x-----2
Solving
Putting the value of y =10+ 2x in equation 1
x +10+ 2x =100
10+3x=100
3x=100-10
x=90/3=30
x=30
y=10 +2x = 10+2x30 =70

Orginally each face of the pyramid shown to the. Right was a triangke withg the dimensions 109m and 190m . How far was a corner of the base from the pyramis top
Answer:
219.05 m²
Step-by-step explanation:
Dimension of right angle triangle : 109 m and 190 m
The right angle triangle has a height of 190 m and base length of 109 m
A corner of the base from the pyramid's top is equivalent to the hypotenus of the right angle triangle :
Let :
hypotenus = c ; base = b ; height = a
Hypotenus² = opposite² + adjacent²
c² = a² + b²
c² = 190² + 109²
c² = 36100 + 11881
c² = 47981
c = sqrt(47981)
c = 219.04565
A corner of the base from the pyramid's top is 219.05 m²

Ellen is drawing two polygons. One of the polygons has 3 more angels then the other. What shapes could she be drawing?
Answer:
Step-by-step explanation:
This is quite and easy one, but also vague at the same time.
A polygon is a shape with 5 or more sides, so, if she were drawing a pentagon, then the second polygon has to be an octagon. A pentagon has 5 sides, and an octagon has 5 + 3 sides
In the same vein, if she were drawing a hexagon, with 6 sides, the other polygon has to be monsoon, with 6 + 3 sides.
A heptagon also gives us a 7 + 3 polygon, in decagon.
All in all, it depends on the first polygon she's drawing as the question is vague in that aspect.

We get both figures to be a rectangular prism.
The Volume of a rectangular prism is length times width times height.
V (of top Rectangular Prism) = 2 × 2 × 4 = 16
V (of bottom Rectangular Prism) = 6 × 4 × 2 = 48
Now, we add those two volumes together to get the volume of the irregular figure.
16 + 48 = 64.

What’s the value of x?
Explain
Answer:
x= -7
Step-by-step explanation:
You need to first add 5 to the -5. Even though the - is a subtraction sign, you can still count it as a subtraction sign. In order to balance it out again, so you add the 5 to the 16. 16+5=21, so the equation would be -3x=21. To get x by itself, you divide by -3. So, -3x/-3 and 21/-3. That gets rid of the -3, and you get a -7 as an answer.

2 + 3 = 5 for every time he makes the recipe
40 / 5 = 8
To double check:
2 x 8 = 16
3 x 8 = 24

The perimeter of a backyard basketball court with four sides is 90 feet. Two sides of the court are each 20 feet long. One side of the court is 25 feet long. What is the missing side length? 20 feet 25 feet 30 feet 50 feet
Given:
The perimeter of a backyard basketball court with four sides is 90 feet.
Two sides of the court are each 20 feet long.
One side of the court is 25 feet long.
To find:
The missing side length of the basketball court.
Solution:
Let x be the missing side length.
The three given sides of the basketball court are 20 feet, 20 feet, 25 feet.
We know that the perimeter is the sum of all sides.
[tex]Perimeter=x+20+20+25[/tex]
[tex]Perimeter=x+65[/tex]
The perimeter of a backyard basketball court with four sides is 90 feet.
[tex]x+65=90[/tex]
[tex]x=90-65[/tex]
[tex]x=25[/tex]
Therefore, the missing side length is 25 feet and the correct option is B.

3.25 times 4 equals 13. So, the plant cost needs to add up to 37. 37 divided by 2.5 is 14.8, or rounded, 15. So she can buy around 15 plants.
50 - 13/2.5 would be the inequality i think.
Please tell me if I did this the wrong way or not.
