Answer:
x ≤ 
Step-by-step explanation:
multipy both sides by twelve
move the variable to the left side and change the sign
collect like terms
divide both sides by -17 and flip the inequality sign
Answer:
Volume of cylinder = 360.010cubic inches
Step-by-step explanation:
Volume of a cone
V = πr^2h/3
V - volume
π - pie
r - radius
h - height
Given
V = 120 inches cubic
π - 3.142
120 = 3.142 * r^2 * h/3
120 = 3.142r^2h/3
120 = 3.142/3 * r^2h
120 = 1.0473r^2h
r^2h = 120 / 1.0473
= 114.580
Make h the subject of the formula
h = 114.580 / r^2
Gotten the value for h, substitute h into the formula for volume of a cylinder
Since the cone and the cylinder has the same base and height
V = πr^2h
h = 114.580/r^2
π - 3.142
V = 3.142 * r^2 * (114.580/r^2)
V = 3.142 * r^2 * 114.580/r^2
r^2 divides r^2
V = 3.142 * 114.580
V = 360.010 cubic inches
Answer:
A. P = 72 feet, A = 300 square feet
Step-by-step explanation:
✔️Perimeter = sum of all sides of the polygon = 15 + 16 + 17 + 8 + 16 = 72 ft
✔️Area of the polygon = area of a trapezoid = ½(a + b)h
Where,
a = 16 ft
b = 16 + 8 = 24 ft
h = 15 ft
Substitute
Area = ½(16 + 24)15
Area = ½(40)15
Area = 300 ft²
Answer:
Yes, they are. Because the variable and exponents of both terms are the same.
Answer:
I'm not to sure but I think it's 39 11/20
Step-by-step explanation:
1/5 + 1/4 you have to get a common denominator which would be 20 and then you add the numerators to get 9. Then you would subtract 40 from 9/20 and have to get the common denominator again which would be 800/20 - 9/20 which is 751/20 simplified to 39 55/100 simplified even more to 39 11/20. I haven't done fractions for a while so it might be wrong. I hope I helped!
