Answer:
Apothem: 6m
hypotenuse : slant height : 6√2 m
height :6m
volume: 288m2
Step-by-step explanation:
Hi, the correct values are: (image attached down below)
Base length= 12m
Slant height is actually = 6√2
So, to calculate the apothem (AC)we apply the Pythagorean theorem:
AB^2 = AC^2 + BC^2
√AB^2 -BC^2 = AC
AC = √(6√2)^2 - 6^2
AC =6 meters
Hypotenuse of ABC = AB =6√2 meters
Height = AC = 6 meters
Volume:
Volume of a pyramid = 1/3 x base area x height
area of a square = side length ^2 = 12^2
V= 1/3 x 12^2 x 6 =288 m2
Answer:
Round up all costs
Least expensive: $6
Most expensive: $13
Half (half of 12 people is 6) ordered $10 calculators so 6x10=$60
Other half
(6+13)/2= $9.5 round up to $10 so 6x10=$60
$60 + 60=$120 best estimate $125
Step-by-step explanation:
Basically you need to find what 15% of 136.45 is. You do this by changing the percent to a decimal, so 15% would be .15. Following this, you would multiply 136.45*.15. This will give your answer.
We subtract the area of the fountain (a(f)) from the total area of the fountain + walk (a(t)), to find the area of the walk (a(w))
diameter of fountain = 10 so r = 5
a(f) = pi*r^2 = pi*25 = 78.5
r of fountain + walk = 5 + 3 = 8
a(t) = pi*r^2 = pi*64 = 200.96
a(w) = a(t) - a(f) = 200.96 - 78.5 = 122.46 square feet
Answer:
Step-by-step explanation:
We have given two function f(x) and g(x)
We need to operate 
Substituting the values in the above format we will get
after opening the parenthesis we will get
We will get after simplification the above expression
Addition of these two functions give us a quadratic expression means an expression with degree or highest exponent two.
