The amount of building material needed to cover the pyramid which Tony's architecture firm is constructing is 144 square feet.
What is area of triangle?The area of the triangle is half of the product of base and height of the triangle. It can be calculated as,
[tex]A=\dfrac{1}{2}b\times h[/tex]
Here, b is the length of base, and h is the height.
Tony's architecture firm is constructing a square pyramid play structure for a school.
The length of one side of the base will be 9 feet, Each face is a triangle with a height of 8 feet. The pyramid will be open at the bottom and not covered.As the height of the triangle is 8 and base is 9 feet of triangle. Thus, the area of one triangular face is,
[tex]A=\dfrac{1}{2}\times9\times8\\A=36\rm\; ft^2[/tex]
Area of 4 triangle side is,
[tex]A=36\times4\\A=144\rm\; ft^2[/tex]
Thus, the amount of building material needed to cover the pyramid which Tony's architecture firm is constructing is 144 square feet.

The ages of 10 boys are listed below.
7, 6, 8, 6, 8, 7, 8, 7, 8, 6
Which of the following best describes the data?
A. The data have range 2, and are otherwise unrelated.
B.The data are evenly distributed, with mean 7.1.
C.The data contain outliers, so the mean is not the best measure.
D.The data have no mode.
Answer:
A. The data has a range of 2.
Step-by-step explanation:
When you subtract 6 from 8 it's 2. Which is the range. Range is the smallest number subtracted from the biggest number.
The data does have a mode. The mode is the number or numbers that repeat more than once. Actually you have more than one mode so. D isn't right.
The data doesn't contain outliers. Outliers are numbers that don't range in with the rest. Meaning if you had the group of nunbers like 10, 10, 13, 54, 14, 12. 54 would be the outlier it isnt in range with the rest of the numbers.
Hope this helped!
The best description of the data set is "the data have range 2, and are otherwise unrelated", which is option A.
The given data set is as follows:
{7, 6, 8, 6, 8, 7, 8, 7, 8, 6}
The mean of the data set is :
(7+6+8+6+8+7+8+7+8+6)/10 = 7.2.
This means that on average, the boys are 7.2 years old.
The range of the data set is 8 - 6 = 2, which is relatively small.
This suggests that there are no extreme values in the data set.
Here, the value 8 occurs most frequently, so the mode is 8.
This means that 8 is the most common age among the boys.
Therefore, the best description of the data is option A.

Water is a very cohesive substance. This means that water particles
A.
are repelled by other types of particles.
B.
are repelled by other water particles.
C.
are attracted to other water particles.
D.
are attracted to other types of particles.
Answer:
C. The charges of the atoms that make up a water molecule makes them attracted to other water particles
The correct option is water particles are attracted to other water particles.
What is cohesive force?The term "cohesive forces" is a generic term for the collective intermolecular forces responsible for the bulk property of liquids resisting separation.
Specifically, these attractive forces exist between molecules of the same substance.
Given that, the water is a very cohesive substance.
We know that, the cohesive substance attracts the molecules of same kinds,
Cohesion means the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces because of their ability to form hydrogen bonds with one another.
Therefore,
The charges of the atoms that make up a water molecule makes them attracted to other water particles.
Hence, the correct option is water particles are attracted to other water particles.

Rectangle Q has an area of 2 square units. Thea drew a scaled version of Rectangle Q and labelled it Rectangle R.
What scale factor did Thea use to go from Rectangle Q to Rectangle R?
Rectangle R is 8 by 9
Answer:
Step-by-step explanation:
It is given that Rectangle Q has an area of 2 square units.
Thea Drew a scaled version of Rectangle Q and marked it as R.
As you must keep in mind If we draw scaled copy of pre-image, then the two images i.e Pre-image and Image are similar.
As you have not written what is the scale factor of transformation
Suppose , Let the Scale factor of transformation= k
Rectangle Q = Pre -image, Rectangle R= Image
If, Pre-Image < Image , then scale factor is k >1.
But If, Pre-Image > Image , then Scale factor will be i.e lies between, 0<k<1.

Q5. A builder rents a digger. He pays a fixed charge of $30 plus $10 per hour to rent the digger. Work out how much he pays to rent the digger for: a) 1 hour b) n hours (1.5 x 2 = 3)
Q6) The width of a rectangle is x centimetres and its length is (x+ 2) cm. Write down an expression for the perimeter of the rectangle, giving your answer in its simplest form. (2+1=3 marks)
Answer:How many hours does he rent it?
Either way, the equation would be 30 + 10x
x is the number of hours he rents the digger.
So for example, if he rented it for say 8 hours
30 + 10(8)
30 + 80
