Answer:
x = 7/3
y = 1/3
Step-by-step explanation:
y = x - 2.... (1)
2x + y = 5.... (2)
Rearranging equation (2), we have
y = -2x +5 .... (3)
Let's multiply equation (1) by 2 so that we can easily simplify by substitution.
Therefore, it becomes 2y = 2x - 4 ... (4)
We add equation (3) and (4)
3y = 1
y= 1/3
Now, substitute (y= 1/3) in equation 1
It becomes:
1/3 = x - 2
x = 1/3 + 2
Simplifying with a LCM of 3
x = (1 plus 6, all over 3)
= 1+6/ 3
= 7/3
Answer:
(At least) 10 centimeters.
Step-by-step explanation:
The radius of the ice cream scoop is 2.5 cm and the radius of the cone is also 2.5 cm.
We want to determine the height of the cone such that it will fit all of the ice cream when it melts without any spilling.
First, we will find the volume of the ice cream scoop. The volume for a sphere is given by:
Since the radius is 2.5 cm, the volume of the full ice cream scoop is:
The volume of a cone is given by:
The radius of the cone is 2.5 cm. Therefore:
The volume of the cone should be equal to the volume of the scoop. So.
The height of the cone should be (at least) 10 cm.

Answer:
54.72
Step-by-step explanation:
- multiply 19% by 0.01
- multiply 0.19 by 288
19·0.01=0.19
0.19·288=54.72
Therefore, 19% of 288 will be 54.72.
