Answer:
149.45 cm²
Step-by-step explanation:
Surface area of pyramid = ½Pl + BA
Perimeter of the base (P) = 7 + 7 + 7 = 21 cm
Slant height (l) = 12.2 cm
Area of base (BA) = ½*bh = ½*7*6.1 = 21.35 cm²
Plug in the values
Surface area = ½*21*12.2 + 21.35 = 149.45 cm²
1.2 Inches, It moves 0.3 inches in 1 hour so if in 1 hour it moves 0.3 and in 2 0.6 and in 3 0.9 so in 4 hours it will move 1.2 inches
I think it's
-0.00017 and -1.7 x 10-4
i hope this helps :)
The next step Juan will take is to multiply the second fraction by (x-2)/(x-2).
Given that Juan needs to rewrite this difference as one expression (3x/(x²-7x+10))-(2x/(3x-15)) and factor the denominator as (3x/(x-2)(x-5))-(2x/3(x-5)).
An algebraic expression in mathematics is an expression composed of variables and constants and algebraic operations (addition, subtraction, etc.). Expressions are made up of concepts.
The given expression is (3x/(x²-7x+10))-(2x/(3x-15))
Firstly, we will factored the denominator as
(3x/(x-2)(x-5))-(2x/3(x-5)).
Now, we will multiply and divide the second fraction by (x-2), we get
(3x/(x-2)(x-5))-((2x(x-2))/3(x-5)(x-2)).
Hence, the next step when subtracting these expressions (3x/(x-2)(x-5))-(2x/3(x-5)) is multiply the second fraction by (x-2)/(x-2).

Answer:
a. Refuel the vehicle before the Renter drives it away.
Step-by-step explanation:
The rental agency representative must check the fuel level, mark it on the check-out sheet and give a copy of the check-out sheet to the renter. He or she does not, however, need to refuel the vehicle for the renter.
