Answer:
80
Step-by-step explanation:
17+13=30
22+23+5=50
30+50=80
Answer:
Combined means to add so you are going to add anything over 1 because it says longer than 1
1 1/4 has 2 marks so you add 1 1/4 + 1 1/4 =
they have like denominators so you can add them together
1 + 1 = 2 and 1/4 + 1/4 = 2/4 which can be reduced to 1/2
so your answer is 2 1/2
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Change the mixed numbers to improper fractions
7 =
6 =
The subtraction is then
-
Both fractions have a common denominator so subtract the numerators leaving the denominator
= = → A
Answer:
6 7/15 cups
Step-by-step explanation:
Add the two measures:
3 4/5 + 2 2/3 = 3 12/15 + 2 10/15 = (3+2) +(12/15 +10/15) = 5 +22/15
= 6 7/15
Leibniz used 6 7/15 cups of flour.
1)
V=hpr^2
r=√(V/(hp)), using 216p for V and 3 ft for h you get:
r=√(216p/(3p))
r=√72
r≈8.5 ft (to nearest tenth of a foot)
2)
The volume of these ice cream cones is half the volume of a sphere plus the volume of a cone...
V=((4pr^3)/3)/2+(hpr^2)/3
V=(4pr^3)/6+(hpr^2)/3
V=(p/3)(2r^3+hr^2)
And the difference between them is:
V=(p/3)(2R^3+HR^2-2r^3-hr^2), given R,H,r,h=3,12,2,8:
V=(p/3)(2*27+12*9-2*8-8*4)
V=(p/3)(114)
V=38p cm^3
V≈119.38 cm^3 (to nearest one-hundredth of a cm^3)
3)
V=[(4pr^3)/3]/2
V=(2pr^3)/3 and when r=15yd
V=2250p yd^3
V≈7068.58 yd^3 (to nearest hundredth of a yd^3)
