Answer:
60 gallons of 70% antifreeze
Step-by-step explanation:
Let n be the amount of 70% antifreeze. And the second brand was 45% pure anti freeze Then:
According to the question
0.7 n+.45(150-n)=0.55(150)
0.7 n+67.5-0.45 n=82.5
0.25×n=15
n=15/.25 = 60
You need 60 gallons of 70% antifreeze, and 90 gallons of 45% antifreeze for this mixture
The pool can contain 10492 gallons of water
What is volume of cylinder?
The capacity of a cylinder, which determines how much material it can carry, is determined by the cylinder's volume. There is a formula for the volume of a cylinder that is used in geometry to determine how much of any quantity, whether liquid or solid, may be immersed in it uniformly. A cylinder is a three-dimensional structure having two parallel, identical bases that are congruent.
Right circular cylinder: A cylinder with circular bases and a lateral curved surface with each line segment perpendicular to the bases.
Oblique Cylinder: A cylinder with sides that are inclined over the base at a different angle than a right angle.
An elliptic cylinder is a cylinder with ellipses at its bases.
Two right circular cylinders tied together inside of one another form a right circular hollow cylinder.
volume of cylinder= (π)
diameter= 18feet
radius = 9 feet
height = 5.5 feet
volume= 3.14*()*5.5
= 1398.87
volume in gallons = 1398.87 * 7.5
= 10492 gallons

If you calculate 640/35=18.3 and then multiply 14 with 18.3 your answer will be the amount of people so ~256
She would have to take 5.29 miles to save round-trip if she had taken the direct route.
<h3>What is the
Pythagoras theorem?</h3>
The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
The direct route from Marta's apartment to work is a road that is a straight line. The road is closed for repairs.
Marta had to drive 8 miles west and then 6 miles south to get to work. She returned home by the same route.
Let's consider x to be the direct route.
By Pythagoras theorem, we can find the direct route
Thus, She would have to take 5.29 miles to save round-trip if she had taken the direct route.
