1 1/12
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(1/3, 3/4) = 12
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(13×44)+(34×33)=?
Complete the multiplication and the equation becomes
4/12+9/12=?
The two fractions now have like denominators so you can add the numerators.
Then:
4+9/12=13/12
This fraction cannot be reduced.
The fraction
13/12
is the same as
13÷12
Convert to a mixed number using
long division for 13 ÷ 12 = 1R1, so
1312=1 1/12
Therefore:
13+34=1 11/2
Answer:
W = 69.5 L = 109.5
Step-by-step explanation:
L = 3W-99
Perimeter = 2L + 2W
358 = 2(3W-99) + 2W
358 = 6W-198 + 2W
358 = 8W-198
556 = 8W
69.5 = W
- 358 = 2L+2W
- 358 = 2L + 2(69.5)
- 358 = 2L + 139
- 219 = 2L
- L = 109.5
Find volume
volumecone=(1/3)(h)(pi)(r^2)
hemisphere is just a half sphere aka, 1/2 times volume of sphere so
hemisphere=(1/2)(4/3)(pi)(r^3)
fnd their volumes don't evaluate the true value till end, leav pi as pi
(or use pi key for graphing or scientific calculators)
cone
d/2=r
10/2=r=5
h=15
V=(1/3)(15)(pi)(5^2)
V=(5)(pi)(25)
V=125pi
hemisphere
V=(1/2)(4/3)(pi)(5.5^3)
V=(4/6)(pi)(166.375)
V=110.91666666666666666pi
which is bigger
125pi or 110.916666666666666666pi
125 pi
by how much?
125pi-110.91666666666666pi=14.08333333333pi
aprox pi=3.14
14.08333333*3.14=44.2217

answer is CONICAL will hold 44 cubic feet more
X = 5
Step-by-step explanation:
78 = 12x+18
-18 -18
60 = 12x
5 = x
