The size of a school increased so that it had 750 pupils instead of 680 and
38 teachers instead of 37. Find the percentage increases in the number of teachers
and pupils. Comment on your answers.
Step-by-step explanation:
% increase in the no of pupils = {(750-680)/680} × 100 = 10.3%
% increase in the no of teachers = {(38-37)/37} × 100 = 2.7%

The dimentionsof the rectangular prisim shown are given im centameters what is the volume of the prism
Complete question :
The dimensions of a right rectangular prism are 1.5 cm, 0.5 cm and 2. 25 cm.
What is the volume of the prism?
A. 0.75 cm
B. 1.6875 cm
C. 3.375 cm
D. 4.25 cm
Answer:
1.6875 cm³
Step-by-step explanation:
Given the dimension :
1.5 cm by 0.5 cm by 2.25 cm
The volume of a rectangular prism is given by :
Volume = Length * width * height
Volume, V = 1.5cm * 0.5cm * 2.25cm
Volume of prism = 1.6875 cm³
Hence, the volume of the rectangular prism is 1.6875 cm³

Thomas paid $4.25 for three apples and four oranges. Five apples and two oranges cost Casey $4.75. Let x represent the number of apples and y represent the number of oranges. Which system of equations represents this situation? A $~3x+4y=4.75~$ $~5x+2y=4.25~$ B 3x+4y=4.25 5x+2y=4.75 C 4x+3y=4.75 2x+5y=4.25 D 4x+3y=4.25 2x+5y=4.75
Answer:
B
Step-by-step explanation:
For the given situation, system of equations is represented by
3x + 4y = 4.25
5x + 2y = 4.75
What is system of equations?"A system of equations is a finite set of equations for which we find the common solution."
According to question,
x represents number of apples
y represents number of oranges.
Two situations are given for which we need to find out which system of equations it represents.
Situation 1 : Thomas paid $4.25 for the three apples and four oranges , which can be represented by equation:
3x + 4y = 4.25
Situation 2: Casey paid $4.75 for five apples and two oranges, which can be represented by equation:
5x + 2y = 4.75
Hence we can conclude that Option B is correct.

What is the surface area of a sphere that has a radius of 5 units? Use 3.14 for π.
The surface area of a sphere is 314.16 square units.
What is a sphere?A sphere is a 3 dimensional figure, which is made up of all points in the space, which lie at a constant distance called the radius, from a fixed point called the center of the sphere.
For the given situation,
The radius of the sphere,r = 5 units
The formula of the surface area of a sphere is
[tex]A=4\pi r^{2}[/tex]
On substituting the above values,
⇒ [tex]A=4(3.14)(5)^{2}[/tex] [∵ π = 3.14]

A FedEx truck has three cargo trailers attached to the back of the cab. If each trailer is 20 feet by 7 feet by 8 feet, how much capacity does the triple trailer have?
Answer:
3360ft^3
Step-by-step explanation:
Volume of each trailer = 20ft * 7ft *8ft
Volume of each trailer = 140*8
Volume of each trailer = 1120ft^3
Since there are 3 of such cargo;
Capacity of the trailer =3(1120)
Capacity of the trailer = 3360ft^3
Hence the capacity of the trailer is 3360ft^3

You need to hire a company to clean your house. Klean company has a fixed cost of $20 and charges $25/hour.
Dustbuster cleaning services, charges $35 per
hour.
a) Write the equations for both companies to calculate the cost of cleaning your house. Include "let" statements.
Answer:
Klean company = 20 + 25h
Dustbuster cleaning services = 35h
Step-by-step explanation:
Let
Number of hours = h
Equation to calculate the cost of cleaning your house
Klean company = 20 + 25h
Dustbuster cleaning services = 35h
Find the number of hours when the cost of cleaning house by both companies will be equal
Klean company = Dustbuster cleaning services
20 + 25h = 35h
20 = 35h - 25h
20 = 10h
h = 20/10
h = 2 hours
Number of hours = h = 2 hours

the layout of a
regular triangular
pyramid. Calculate
how many square
centimeters of paper
are needed to make
this pyramid. Provide
the answer to the
nearest square
centimeter.
Answers:
a) 693 sq cm (approximate)b) 48 sq cm (exact)============================================================
Explanation:
Part (a)
A regular triangular pyramid, aka regular tetrahedron, has all four triangles that are identical copies of one another. They are congruent triangles. This will apply to part (b) as well.
To find the area of one of the triangles, we'll use the formula
A = 0.25*sqrt(3)*x^2
where x is the side length. This formula applies to equilateral triangles only.
In this case, x = 20, so
A = 0.25*sqrt(3)*x^2
A = 0.25*sqrt(3)*20^2
A = 173.20508 approximately
That's the area of one triangle, but there are four total, so the entire area is about 4*173.20508 = 692.82032 which rounds to 693 sq cm.
The units "sq cm" can be written as "cm^2".
----------------------------
Part (b)
We'll use the same idea as part (a). But the formula to find the area of one triangle is much simpler.
The area of one of the triangles is A = 0.5*base*height = 0.5*6*4 = 12 sq cm.
So the area of all four triangles combined is 4*12 = 48 sq cm
This area is exact.
The area of each 2D flat net corresponds exactly to the surface area of each 3D pyramid. This is because we can cut the figure out and fold along the lines to form the 3D shapes.

49. When a store releases a new cell phone to customers, it expects its sales to decrease by 5% each month after the initial month. If the store sells 682 of a particular phone the first month, which exponential function models this situation x months after the initial month?
A f(x) = 682 • 1.05^x
B f(x) = 682 • 0.05^x
C f(x) = 682 • 0.95^x
D f(x) = 682 • 1.95^x
Answer:
C) f(x)= 682 • 0.95^x
Step-by-step explanation:
The formula for Exponential Decrease is given as:
y = a(1 - r)^x
Where
y = f(x)
a = Initial size of the population = 682
r = Growth rate = 5% = 0.05
x = Time is years
Therefore, our equation can be written as:
f(x) = 682 × (1 - 0.05)^x
f(x) = 682 × (0.95)^x
Therefore, the exponential function that models this situation x months after the initial month is
option C)
f(x) = 682 • 0.95^x

What is the area of a circle that has a circumference of 125 feet?
Answer:
A≈1243.4ft²
Step-by-step explanation:
A=πr2
C=2πr
Solving forA
A=C2
4π=1252
4·π≈1243.39799ft²
Answer:
1243.4
Step-by-step explanation:
You can find the area of a circle from circumference with a few different formulae.
c = 2πr, or 19.89 * π = 125
Then, now that you know the radius, you can use the formula A = πr².
1243.4 = 395.79
