Answer:
B) 122.5π cm3
Step-by-step explanation:
Volume of a cylinder = 
r= radius , but we are given diameter or 7cm, radius = diameter/2 =7/2 = 3.5cm
h= height, given as 10cm
Next, plug in the numbers into the formula;
Therefore, the volume of soup in the can is 122.5
Easily, take the square root of the number in the right side to find the radius
is the answer
Answer: <em>c) 4a² - ab</em>
Step-by-step explanation:
<em>A = (2a)² - ab = 4a² - ab</em>
For
ax+by=c
slope=-a/b
perpendiculare lines have slopes that multiply to -1
so
2x+3y=9
slope=-2/3
-2/3 times what=-1
what=3/2
point slope form
the equation of a line that passes through the point (x1,y1) and the slope is m is
y-y1=m(x-x1)
slope=3/2
point i (8,5)
equation is
y-5=3/2(x-8)
converted to standard form
2y-10=3x-24
-3x+2y=-14
3x-2y=14
The bags of candy that was sold is 6
The bags of cookies that was sold is 10.
<h3>What are the linear equations that represent the question?</h3>
$8.50c + $4.50o = 79 equation 1
o - c = 6
o = 6 + c equation 2
Where:
<h3>How many bags of candy and cookies were sold?</h3>
Substitute for o in equation 1 using equation 2
$8.50c + $4.50(6 + c) = 79
$8.50c + 27 + 4.50c = 79
$8.50c + 4.50c = 79 - 27
$13c = 52
c = 52 / 13
c = 4
Substitute for c in equation 2
0 = 6 + 4 = 10
