The correct answer would be the first one
Answer:
1/2 + 2/3 + 5/4 = 29/
12
= 2 5/ 12 ≅ 2.4166667
Step-by-step explanation:
Add: 1/
2 + 2/
3 = 1 · 3/
2 · 3 + 2 · 2/
3 · 2 = 3/
6 + 4/
6 = 3 + 4/
6 = 7/
6
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(2, 3) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 3 = 6. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - one half plus two thirds = seven sixths.
Add: the result of step No. 1 + 5/
4 = 7/
6 + 5/
4 = 7 · 2/
6 · 2 + 5 · 3/
4 · 3 = 14/
12 + 15/
12 = 14 + 15/
12
= 29/

The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 4) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 4 = 24. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - seven sixths plus five quarters = twenty-nine twelfths.

Answer:
I’m not sure what the question is since you are just giving me the information, but I’m gonna tell you this:
History >> 2 hrs
Chem >> 30 mins
Alg 2 >> 1 hr 30 mins
Hope this helps!
__________________________________
Step-by-step explanation:
4 hours << total
Half her time on history>>4/2>>2 hrs on history
Leftover time>>4-2=2 hrs left
A fourth of leftover time on chem>>2hrs/4 = 30 mins on chem
What’s left? 2hrs - 30 mins= 1hr and 30 mins << leftover <<alg 2
Check the picture below.
recall that the trajectory of an object flying is, it goes up up up, reaches a maximum height and then down down down, till it hits the ground, when it happens it's not longer above ground, thus height = 0.
Let the width be x. Since the length is 30inches longer than the width, the length is 30 + x.
Area = length x width = (30 + x)(x)
i.e. (30 + x)(x) = 1800 square inches.
x + 60 = 0 or x - 30 = 0
x = -60 or x = 30
but the width cannot be a negative number, hence x = 30inches
i.e. width = 30 inches
length = 30 + 30 = 60 inches.
