6= -s + 77<br> Given the above equation, what is the value of <br> 1 + 5(77 - s)?
sveta [45]

Answer:

1 + 5(77 - s) = 31

Step-by-step explanation:

Solve for s:

-s+77=6\qquad\text{subtract 77 from both sides}\\\\-s=-71\qquad\text{change the signs}\\\\s=71

Put the value of <em>s</em> to the expression 1 + 5(77 -s):

1+5(77-71)

Use PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

=1+5(6)=1+30=31

A cone has a volume of 301.44 cubic yards and a radius of 6 yards. What is its height?
alexira [117]

Answer:

h≅ 8 yards

Step-by-step explanation:

Given data

Volume of cone= 301.44 cubic yards

Radius of cone= 6 yards

Required

The Height of the cone

The expression for the volume of a cone is given as

V= 1/3πr^2h

Substitute

301.44= 1/3* 3.142*6^2*h

301.44= 37.704*h

Divide both sides by 37.704

h= 301.44/37.704

h= 7.99

h≅ 8 yards
