4 students
Step-by-step explanation:
The average = sum of all observations divided by a number of observations. Sum of heights of 4 students = 1.44 ×4 = 5.76. Clearly, height of student who left = Sum of all heights - Sum of heights of 4 students.
Where are earthquakes generally more violent violent
(a) along a plate boundary where tension is released frequently or
(b)along a boundary where tension builds up over a greater period of time
Answer:
B
Step-by-step explanation:
Earthquakes are formed when a plate is stuck and it later releases (which creates the shaking). The more tension, the greater an earthquake is.

Step-by-step explanation:
again, 2 unknowns.
x = number of 2- points baskets
y = number of 3- points baskets
we know they hit the basket 37 times in a so far unknown mixture of 2-point and 3- point throws.
x + y = 37
which gives us e.g.
x = 37 - y
and we know that with this unknown mixture they scored 80 points.
so,
2x + 3y = 80
as every successful 2-points throw scores 2 points, and every successful 3-points throw scores 3 points.
so, again our 2 equations :
x = 37 - y
2x + 3y = 80
remember, we prepared the first equation so that it gives us already an identity expressing one variable by the other. and that we use in the second equation :
2×(37 - y) + 3y = 80
74 - 2y + 3y = 80
74 + y = 80
y = 6
and from
x = 37 - y
we get
x = 37 - 6 = 31
so, they had 31 2-points throws and 6 3-points throws.
If mZT = (2x + 85), m ZV = (5x + 29)", and
the sum of the measures of the angles is
930, find the measure of each angle.
Answer:
Solving for x;
2x + 85 + 5x + 29 = 930
combine like terms:
7x + 114 = 930
-114 -114
7x = 816
/7 /7
x = 116.57, now we replace the x with it's actual value:
∠ZT = 2(116.57) + 85 = 318.14°
∠ZV = 5(116.57) + 29 = 611.85°, lets double check if they both equal 930;
318.14 + 611.85 = 929.99, which is close to 930 so we are correct.

A new car is purchased for 22300 dollars. The value of the car depreciates at 7.5% per year. To the nearest year, how long will it be until the value of the car is 7700 dollars?
Answer:
13 years the value of the car is 7700 dollars.
Step-by-step explanation:
Your search - { Present Volue = initial value (1-7.5%) t t is the years
∴7700 = 22300 (1-7,5%)^t
= $10.925 ) t = [tex]\frac{7700}{23300}[/tex] = 0.345 t=13
Supplement:
I year.
P value = 22300- 22300.7.5%
2 years
p value = (122300 - 22300. 7.5% ) - (22300-223107.5%)
= (22300 - 12300.7.5% ) (1-7.5%)
= 22300 (1-7.5%)(1-7.5%).
so t years :
p value = 22300 (1-7.5%)^t
which is the largest of 4.187 or 4.2 or 4.099
4.2 is biggest 4.2 is bigger than 4.18

The sum of all the angles of a triangle is equal to 180°. The value of x is 12.
What is the sum of all the angles of a triangle?The sum of all the angles of a triangle is equal to 180°.
What is the exterior angle?The Exterior Angle is the angle formed by either of a shape's sides and a line drawn from the opposite side.
We know that in a triangle the sum of the exterior angle and the interior angle is 180°. Therefore, the following angles of the triangle can be written as,
[tex]\angle H=180-(9x+6)[/tex]
[tex]\angle G=180-(10x-1)[/tex]
[tex]\angle J=180-(10x+7)[/tex]
Now, the sum of all the angles of the triangle is 180°, therefore, the sum can be written as,
[tex]\angle H+\angle G+\angle J=180^o\\\\180-(9x+6) + 180-(10x-1) + 180-(10x+7) = 180\\\\540-(9x+6)-(10x-1)-(10x+7)=180\\\\540-180 = (9x+6)+(10x-1)+(10x+7)\\\\360=9x+6+10x-1+10x+7\\\\360=29x+12\\\\360-12=27x\\\\x = 12[/tex]

Given the similar pyramids pictured below.
The volume of pyramid 1 is 675 cm3 and its surface area is 504 cm2 If the volume of pyramid 2 is 3125 cm3 , what is its
surface area?
Answer:
1400 cm²
Step-by-step explanation:
The ratio of volumes of similar figures is the cube of the scale factor. Here, that is 3125/675 = sf³. That means the scale factor is ∛(3125/675) = 5/3.
The ratio of areas of similar figures is the square of the scale factor. Here, that is (5/3)² = 25/9.
The area of the larger pyramid is 25/9 times the area of the smaller one:
A = (25/9) × 504 cm² = 1400 cm²
The surface area of pyramid 2 is 1400 cm².

Additional comment
You don't need to find the scale factor. You can jump directly to the fact that the surface area multiplier is the 2/3 power of the volume ratio.

Convert the mixed number 5 4/9 to an improper fraction.
Answer:
[tex]=\frac{49}{9}[/tex]
Step-by-step explanation:
Given the following question:
[tex]5\frac{4}{9}[/tex]
In order to convert a mixed number into an improper fraction, you have to multiply the denominator by the whole number (in this case; 9 and 5) and then add the numerator (in this case; 4) to receive your answer. Of course, keeping the denominator the same.
[tex]5\frac{4}{9}[/tex]
[tex]5\frac{4}{9}=9\times5=45+4=49=\frac{49}{9}[/tex]
[tex]=\frac{49}{9}[/tex]
Hope this helps.
The improper fraction for the given mixed fraction is 49/9.
The given fraction is [tex]5\frac{4}{9}[/tex].
These are just improper fractions written as a sum of whole number and a proper fraction. (improper fraction has the upper value(also called numerator) bigger or equal to denominator(the bottom value) and proper fraction has numerator value is less than that of the denominator)
They are written and can be converted to fraction as [tex]a\frac{b}{c}=\frac{(a\times c)+b}{c}[/tex]
Now, [tex]5\frac{4}{9}=\frac{(5\times9)+4}{9}[/tex]
= (45+4)/9
= 49/9
Therefore, the improper fraction for the given mixed fraction is 49/9.

The length of a rectangular storage room is 2 feet longer than its width if the area of the room is 195 square feet, find its dimensions
The dimensions of the rectangular storage room are length = 15 ft and width = 13 ft
Let the
L = length of the rectangular storage room and W = width of rectangular storage room.Givent hat its length is 2 feet longer than its width, we have that
L = W + 2
Area of a rectangleThe area of the room is a rectangle A = LW where
L = length of room and W = width of roomSince the area of the room A= 195 ft², we have that
A = LW
LW = 195
The width of the rectangular storage roomSubstituting the value of L into the equation, we have
LW = 195
(W + 2)W = 195
W² + 2W = 195
W² + 2W - 195 = 0
W² + 15W - 13W - 195 = 0
W(W + 15) - 13(W + 15) = 0
(W + 15)(W - 13) = 0
W + 15 = 0 or W - 13 = 0
W = -15 or W = 13.
Since W cannot be negative, W = 13 ft
The length of the rectangular storage room
Since L = W + 2
Substituting W into the equation, we have
L = 13 + 2
L = 15 ft
So, the dimensions of the rectangular storage room are length = 15 ft and width = 13 ft
