48 ounces converted into pounds would equal to 3 pounds.
Answer:
X=11+ √157/12
x= 11-√157/12
Step-by-step explanation:
2x+3=12x^2 -20x
Move all terms to one side.
2x+3−12x2+20x=02x+3−12x ^2+20x=0
Simplify
22x+3−12x^2=0
Use the Quadratic Formula.
a= -12
b= 22
c= 3
I'm assuming the equation is (2 * r) * (t - 3)... then you will just need to substitute the answers into the equation:
(2 * 2) * (6 - 3) = 4 * 3 = 12
Answer:
the area of the triangle is 17.4cm^2
Step-by-step explanation:
Finding the area of a triangle
an isosceles triangle has two sides of equal length.
therefore to get the base of the triangle :
we need to subtract the lengths from he perimeter
30-12-12
= 6
<u>the base of the triangle is 6 cm</u>
<u></u>
<h3><u>area of a triangle</u></h3>
formula :
<h3><u>getting the height of the triangle:</u></h3>
we make use of one side of the triangle , half the base. this creates a right angled triangle
we can make use of the formula
were c is the hypotenuse of 12 cm
a is the adjacent of base (6/2) = 3 cm
and b is the height
b = 11.6 cm to 3sf
<u>the height is 11.6cm.</u>
<u></u>
<em>area of the triangle is :</em>
1/2 * 3 * 11.6
<u>= 17.4 cm^2</u>
<u />
<u>the area of the triangle is 17.4cm^2</u>
Answer:
A. 2.10b + 12.99 = 21.39; 4 bottles
Step-by-step explanation:
The b represents bottles of water, at the end of the equation. If each bottle is $2.10, and there were 4 bottles brought, $2.10 * 4 = $8.40, and $8.40 + $12.99 is $21.39.
