Answer:
C= 30
Step-by-step explanation:
Answer:
1. 1/3 * 7 = 7/3 = 2 1/3 or two and one-third
2. 7/9 * 3/5 = (3*7)/(9*5) = 21/45
dividing numerator and denominator by 3
21/45 = 7/15 or start fraction seven over fifteen end fraction
3. 2 2/3 is equivalent to 8/3, then:
8/3 * 9 = 8 * 9/3 = 8 * 3 = 24
4. -4 1/2 is equivalent to -9/2
-2 1/3 = -7/3
Then:
-4 1/2 * (-2 1/3) = -9/2 * (-7/3) = -3/2 * (-7) = 21/2 = 10 1/2 or 10 one-half
5. (1/3) / (5/6) = 1/3 * 6/5 = 2/5 or two-fifths
6. 3 1/5 is equal to 16/5
16/5 ÷ 8 = 16/5 * 1/8 = 16/8 * 1/5 = 2 * 1/5 = 2/5 or The fraction is 2 over 5.
7. (-3/5) / (-3/4) = -3/5 * (-4/3) = 12/15
dividing each term by 3:
4/5 or The fraction is 4 over 5.
8. -3 1/5 si equivalent to -16/5
-3 1/5 ÷ 2/15 = -16/5 * 15/2 = -16/2 * 15/5 = -8 * 3 = -24
Answer:
no solution
Step-by-step explanation:
Answer: 2.25 grams
Explanation:
To find the remaining mass of an element, apply the following:
m0 = m/(2^n), where m0 is the remaining mass, m as the original mass and n as the number of half lives that have passed.
we have m, we just have to find n. To find n,
24/6 = 4 half lives have passed.
Applying the first formula,
m0 = (36)/(2^4) = 36/8 = 2.25 grams
Hope this helps, brainliest would be appreciated :)
Answer:
NO IF 14 POUND BURGERS
NO IF 1/4 POUND BURGERS
Step-by-step explanation:
2 3/8 POUNDS < 10
10- 2 3/8 = 7 5/8 REQUIRED TO MAKE 10 1 POUND BURGERS
If 1/4 pound burgers then you can just divide 1/4 into 2 3/8
= 2 3/8 / 1/4 = 9.5 BURGERS = No
Because 10-9.5 = 0.5 burger required
1/2 burger is not equivalent to 1 whole burger.
