Answer:$2.25x
Step-by-step explanation:
Lets use X to denote the amount of stickers How and his friends bought. so he buys them at 1.25x. An easy trick when doing percentages of a number is thinking of the percent as a fraction. So instead of 180, think of 180/100. Think of 1.25 as 125/100
multiply 180/100 by 125/100
you get 22500/10000 which equals 2.25
or 2.25x
In what ways were the causes and the effects of revolutions between 1750 and 1900 similar and different?.
From 1750 to 1900, Europe's strength and dominance over the world grew dramatically.
New western political concepts developed strong, centralized states that directed empires all around the world, while industrialization created unprecedented wealth.
The following are the reasons and impacts of the various revolutions that occurred between 1750 and 1900:
The globe became really autonomous as a result of industrialization.
Such countries, in quest of raw supplies and markets, encroached on other countries' economic interests.Many people migrated to big cities as a result of population expansion.Slaves and serfs were liberated because free-wage work was favored over forced labor.In comparison to men, women were paid significantly less.This drove women to struggle for their own political rights.People from the working class arrived as a force for change.They were able to push for changes to their terrible working conditions through the formation of unions.

The equation of the line would be y = (-3/4)x + 5.
What is the slope-point form of the line?
For the line having slope "m" and the point (x1, y1) the equation of the line passing through the point (x1, y1) having slope 'm' would be
y - y1 = m(x - x1)
The given equation is [tex]y=-\frac{3}{4}x-17[/tex]
The required line is parallel to the given line.
and we know that the slopes of the parallel lines are equal so the slope of the required line would be m = -3/4
And the required line passes through (8, -1)
so by using slope - point form of the line,
y - (-1) = (-3/4)(x - 8)
y + 1 = (-3/4)x - (-3/4)8
y + 1 = (-3/4)x + 24/4
y = (-3/4)x + (12/2 - 1)
y = (-3/4)x + 5
Hence, the equation of the line would be y = (-3/4)x + 5.

Step-by-step explanation:
since f(x) = 2×x + 1
therefore f(2.99) = 2×2.99 + 1 = 6.98 ≈ 7
therefore f(2.999) = 2×2.999 + 1 = 6.998 ≈ 7
therefore f(3.01) = 2×3.01 + 1 = 7.02 ≈ 7
therefore f(3.001) = 2×3.001 + 1 = 7.002 ≈ 7
now for the what conclusion can you draw from these results i dont 100% know but i think he wants that

The volume of a large can of tuna fish can be calculated using the formula V = πr²h. Write an equation to find the radius, r, in terms of V and H.
Answer:
[tex] r = \sqrt{\dfrac{V}{\pi h}} [/tex]
Step-by-step explanation:
V = πr²h
Switch sides.
πr²h = V
Divide both sides by πh.
r² = V/(πh)
Take the square root of both sides.
r = √[V/(πh)]

-x-7y-14
-4x-14y=28 solve by elimination
Answer:
x= -28
y= 6
Step-by-step explanation:
-x-7y = -14
-4x-14y=28
Let's find x first! First, we time the first equation by -2
2x + 14y = 28
-4x -14y = 28
Add them; you will get
-2x = 56
x = -28
Then put -28 back in the x, and you will get

Choose the equation of a line parallel to the given equation and passing through a point P. x + 2 y =5 ; ( 2,-5)
A.) Y = 2 x -4
B.) Y = -1/2x -1
C.) Y = -1/2x -4
D.) Y = -2 x -1
Answer:
The correct answer is C: Y = -1/2x - 4.The slope of the given line is -1/2, so any line that is parallel to it will have the same slope. In order to find the equation of a line with the same slope that passes through the point (2, -5), we can use the point-slope form of the equation of a line.The point-slope form of the equation of a line is:y - y1 = m(x - x1)where m is the slope of the line, and (x1, y1) is a point on the line.In this case, we can plug in the values m = -1/2, x1 = 2, and y1 = -5 to get:y + 5 = -1/2(x - 2)Solving for y, we get:y = -1/2x - 4Therefore, the equation of the line that is parallel to the given line and passes through the point (2, -5) is Y = -1/2x - 4.

What is Osteogenesis Imperfecta (OI)?Osteogenesis imperfecta (OI) is an inherited or genetic bone disorder which is present at birth. It is also known as brittle bone disease. A child born with OI may have soft bones which fracture easily, bones which are not formed normally, and other problems. Signs and symptoms may range from mild to severe.
Life expectancy for OI babies vary greatly depending on OI type. Babies with Type II generally die soon after birth. Children with Type III may live longer, but mostly only until around age 10.
About 90% of OI cases are caused by autosomal dominant mutations in the type I collagen genes. Mutations in one or the other of these genes cause the body to make either abnormally formed collagen or too little collagen. Mutations in these genes cause OI Types I through IV.

There are 324 miles can Mario drive with 9 gallons of gas.
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;
He can drive 18 miles on ½ a gallon of gas.
Now,
Since, He can drive 18 miles on ½ a gallon of gas.
Let the number of miles cover with 9 gallons of gas = x
So, By definition of proportion, we get;
⇒ 18 / (1/2) = x / 9
⇒ 18 × 2 = x / 9
⇒ 36 × 9 = x
⇒ x = 324 miles
Thus, The number of miles cover with 9 gallons of gas = 324 miles

The position of mailbox after 10s is equal to sum displacements is 14m.
The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).
Given velocity time graph understand in three parts.
1. first 6s mailbox have constant velocity 3m/s
the displacement covered by it = area under v-t graph(square shape)
s1=3 x 6 =18m
2. the mailbox at rest at 6-8 s.
the displacement covered by it s2=0
3. the mail returned with constant velocity 2m/s
Displacement is defined to be the change in position of an object. It can be defined mathematically with the following equation:
Displacement=Δx=[tex]x_{f} - x_{0}[/tex]
[tex]x_{f}[/tex]=refers to the value of the final position.
[tex]x_{0}[/tex]= refers to the value of the initial position.

Applying the definition of the median of a triangle, the length of AO is calculated as: 14 units.
What is the Median of a Triangle?The median of a triangle is a line segment that joins the midpoint of a side of a triangle and the opposite vertex to the side.
There are three medians in a triangle, and the three of them intersect at a point inside the triangle. This point of intersection is known as the centroid.
According to the centroid theorem of a triangle, the length from the vertex to the centroid is two-third of the length of a median.
Thus, the figure shows that triangle ABC has three medians, BL, AM, and CK, which intersect at point O. This means the centroid of the triangle is point O.
By implication, it means that:
Length of AO = 2/3 * (length of AM)
Plug in the value of AM:
Length of AO = 2/3 * (21) [centroid theorem]
