Answer:
Lisa bought 9 gallons of ice cream
Step-by-step explanation:
lets take "x" as the gallons of lemonade
if Lisa made purchases worth $34 that is what our equation will e equal to
ice cream:7.5 per gallon
milk: 2.5 per gallon
lemonade: 3 per gallon
since Lisa purchases 4 gallons of milk and 2 gallons of ice cream we will multiply that by the unit money for each food respectively:
7.5(2)+2.5(4)+X=34
SIMPLIFY:
15+10+x=34
15+10=25
25+x=34
25-25+x=34-25
x=9
Lisa bought 9 gallons of ice cream
hope this helps!
OK. I did it. Now let's see if I can go through it without
getting too complicated.
I think the key to the whole thing is this fact:
A radius drawn perpendicular to a chord bisects the chord.
That tells us several things:
-- OM bisects AB.
'M' is the midpoint of AB.
AM is half of AB.
-- ON bisects AC.
'N' is the midpoint of AC.
AN is half of AC.
-- Since AC is half of AB,
AN is half of AM.
a = b/2
Now look at the right triangle inside the rectangle.
'r' is the hypotenuse, so
a² + b² = r²
But a = b/2, so (b/2)² + b² = r²
(b/2)² = b²/4 b²/4 + b² = r²
Multiply each side by 4: b² + 4b² = 4r²
- - - - - - - - - - -
0 + 5b² = 4r²
Repeat the
original equation: a² + b² = r²
Subtract the last
two equations: -a² + 4b² = 3r²
Add a² to each side: 4b² = a² + 3r² . <=== ! ! !
Answer:
47.3 m³
Step-by-step explanation:
The garden shed is made up of a rectangular prism and a pyramid.
<h3><u>Volume of a rectangular prism</u></h3>
<h3><u>Volume of a pyramid</u></h3>
<u />
From inspection of the given diagram, the slant height of the pyramid is 3.5 m.
Calculate the perpendicular height of the pyramid using Pythagoras Theorem:
Therefore:
<h3><u>Volume of the garden shed</u></h3>
