Since there is a common difference of one, this is an arithmetic sequence of the form a(n)=a+d(n-1) which in this case is:
a(n)=15+1(n-1)
All arithmetic sequences have a sum which is equal to the average of the first and last terms time the number of terms, mathematically:
s(n)=(2an+dn^2-dn)/2 (that is just the result of ((a+a+d(n-1))(n/2)) )
Since a=15 and d=1 this becomes:
s(n)=(30n+n^2-n)/2
s(n)=(n^2+29n)/2 so
s(10)=(100+290)/2
s(10)=195 logs
The original price of the clubs will be $135.
If the clubs at Nine Iron are $8 less than Golf Pros, they are 112.
120 - 8 = 112
Now, we just have to find the original price. We can write and solve the equation below to find the original price.
x (0.83) = 112 Divide both sides by 0.83
x = $135
Answer:
63cm³
Step-by-step explanation:
The shape above is a rectangular prism
The formula for a rectangular prism is given as:
= Length × Width × Height
Length = 3cm
Width = 3cm
Height = 7cm
= 3cm × 3cm × 7cm
= 63 cm³
The volume of the rectangular prism = 63cm³
9. Area of a triangle is proportional to height. If the height increases by a factor of 4, then ...
The area will increase by a factor of 4. . . . . (2nd selection)
10. The base lengths and height are needed:
• 5 mm
• 8 mm
• 10 mm
