The teacher and her students are playing a game. The students take turn to say from 1 to 100 (1 student says 1 number in each tu

rn). However, in the turn that students need to say the number which has the digit 7, they need to say "Buzz" instead. For example, if Hoa has number 17 in her turn, Hoa will say "Buzz" instead of "seventeen". How many times will the students say "Buzz" in total?

A pyramid-shaped hip roof is a good choice for a house in an area with many hurricanes. What is the volume of the roof to the ne
Lubov Fominskaja [6]

The volume of the roof is 10667 cube feet and the volume of the entire house, including the roof, is 58667 cube feet.

<h3>How to find the volume of the composite figures?</h3>

To find the volume of the composite figures, follow the steps listed below:,

  • Separate the figure.
  • Calculate the volume of each figure by which the composite figure is made of.
  • Add the volume of all the individual figures to get the total volume of composite figures.

A pyramid-shaped hip roof is a good choice for a house in an area with many hurricanes. The volume of the roof is:

V=\dfrac{1}{3}(\text{length x width x height})\\V=\dfrac{1}{3}40\times40\times20\\V\approx10667\rm\; ft^3

The volume of the room is:

V=length x width x height

V=40 x 40 x 30

V=48000 ft³

The volume of the entire house, including the roof, is,

V=10667+48000

V=58667 ft³

Thus, the volume of the roof is 10667 cube feet and the volume of the entire house, including the roof, is 58667 cube feet.

Find the complement of the set given that
natima [27]

The complement of the set is {8, 9, 10, 11}

<h3>How to find the complement of the set?</h3>

The universal set is given as:

U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}.

The other set is given as:

{x | x is in N and x < 8}

The complement of the set is the set elements that are in the universal set, but not in the given set

The set {x | x is in N and x < 8} can be rewritten as

X = {0, 1, 2, 3, 4, 5, 6, 7}

So, the complement is

X' = {8, 9, 10, 11}

I need to find the answer someone please help
Ludmilka [50]

Answer:

About 1,237 cubic feet.

Step-by-step explanation:

The first step is to know the formula for the volume of a cylinder.

V = pi * r^2*h

You have all the numbers needed because 7ft is the height and the half the diameter (or half of 15) is 7.5. so:

V = pi * 7.5^2 * 7

Which of the following is the complete list of roots for the polynomial function f(x)=(x2+6x+8)(x2+6x*13)
anygoal [31]
Factorise x^2+6x+8=0 to get (x+4)(x+2)=0
Solve to get x=-4, x=-2
Factorise x^2+6x+13=0 (I assumed you mistyped and wrote * instead of +)
Use the quadratic formula and you find that there are no real roots so the answer for this is just x=-4, x=-2
