Answer:
So, after 6 months, they both have the same number of coins.
Step-by-step explanation:
Jack has 56 coins
Jill has 80 coins
Jack collect 12 coins per month
Jill collect 8 coins per month
Let after m months, they both have the same coin.
56 + 12 m = 80 + 8 m
12 m - 8 m = 80 - 56
4 m = 24
m = 6
So, after 6 months, they both have the same number of coins.
Answer: 1,200 ml
Step-by-step explanation:
The ratio is 1 : 5.
If 200 ml of concentrate is used, the water used will be:
1 : 5
200 : x
x = 1,000 ml of water
The amount of juice would be:
= water + concentrate
= 1,000 + 200
= 1,200 ml
Answer:
C. 21.98
Step-by-step explanation:
In this case, you would have to multiply 3.14 times 7. If you didn't have the diameter, and all you had was the radius, you had find half of seven, which is 3.5, multiply that by 2, and finally multiply that answer by 3.14. Hope this helps! Have a nice day :D
Answer:
94 m
Step-by-step explanation:
Write a proportion:
3.1 / 1.18 = x / 35.75
Cross multiply and solve:
1.18x = 3.1 × 35.75
1.18x = 110.825
x ≈ 94
Rounded to the nearest meter, the height of the tower is approximately 94 meters.
Answer:
D
Step-by-step explanation:
A negative discriminant indicates that the quadratic equation has no real roots.
Thus the graph does not touch or intersect the x- axis
The only graph that does not touch or intersect the x- axis is the fourth one
