36 + x = 144
144-36= 108
square root of 108 is, around 10.4
22% since 100-78 is 22 so that is the percentage of numbers between 78 and 100
Answer:
-24
Step-by-step explanation:
g(-2) = 2(-2)
g(-2) = -4
h(4) = 4² + 4
h(4) = 16 + 4
h(4) = 20
g(-2) - h(4)
-4 - 20
= -24
X=-10
by simplifying both sides of the equation then isolating the variable
Answer:
<em>213,645.6cm³ </em>
Step-by-step explanation:
Area of a cylinder is expressed as;
V = πr²h
r is the radius = 2cm
h is the height = 70cm
Get the volume of one rod;
V = πr²h
V = (3.14)(2)²(70)
V = (3.14)(4)(70)
V = 879.2cm³
one steel = 879.2cm³
243 rods = x
Cross multiply;
x = 879.2 * 243
<em>x = 213,645.6</em>
<em>The company will need 213,645.6cm³ volume of steel to make 243 rods</em>
